AB  - In the last decades, old production technology used on farms on mountain of Stara planina was the reason why milk production wasn't profitable activity and therefore livestock production had collapse. In this paper current situation is analyzed and new knowledge introduced in production of sheep and cow milk on farms located in that region. The analysis of breed structure shows that in population of Pirot Pramenka sheep and local Simmental population of cattle, effects in milk production are rather poor. Introduction of modern knowledge of milk production would considerably increase the milk yield of sheep and cows and motivate the rural population to revive dairy livestock production. Through application of new solutions regarding of breeding and farm organizations, milk yield in sheep was increased per head by 8-15%, and quantity of milk in cows was increased by 10-16%. Also the health condition of the udder was improved and somatic cell count was reduced within the limits regulated by law.
AB  - Poslednjih decenija, zastarela tehnologija proizvodnje je učinila da mleko nije isplativ posao, pa je stočarstvo u planinskim krajevima doživelo kolaps. U radu se analizira postojeće stanje i koriste nova saznanja u proizvodnji ovčijeg i kravljeg mleka na malim farmama u centralnom delu Stare planine. Analiza rasne strukture pokazuje da u populaciji ovaca pirotske pramenke dnevna mlečnost varira od 0,3-0,5kg po grlu, odnosno 60-90 kg u laktaciji. U populaciji goveda, dnevna proizvodnja mleka iznosi 10-15 kg, dok se prosečna mlečnost u laktaciji kreće od 2400-3000 kg. Primenom inoviranih rešenja, kod ovaca je povećana mlečnost po grlu između 8-10% dok kod boljih farmera, gde je uveden i dodatak koncentrata, mlečnost je popravljena za 15%. Prosečna količina mleka kod krava je povećana za 16,40%. Poboljšano je i zdravstveno stanje vimena, tako da mleko ne sadrži veći broj somatskih ćelija nego što je zakonom propisano.

AB  - Results of the investigation of the effect of the level of nondegradable protein in concentrate mixtures on digestibility of nutritive substances in fattening lambs are presented in this paper. Physiological research included 18 male lambs crosses Pirot Pramenka x Württemberg x Ile de France, average body mass of approx. 35,0 kg, divided into three groups. Lambs were fed iso-protein concentrate mixtures which differed in relation to share of protein non-degradable at the rumen level: 43% (I), 51% (II) and 58% (III). Trial results indicate that the level of protein adoption was not under the influence of investigated treatment, considering that digestibility coefficients were: 52,58% : 51,30% : 55,12%. With the increase of share of nondegradable protein in concentrate mixtures (43: 51: 58%), also tendency of increase of fat digestibility was observed: 76,13 : 77,98 : 87,17%, but decrease of degree of cellulose digestion: 67,40 : 45,87: 22,39% and NFE: 83,87 : 76,05 : 82,96%.

AB  - Research included 3.461 first calving Simmental cows in control, with lactations concluded within one year. All first calving cows were reared by private/individual farmers on the territory of the Republic of Serbia. Phenotypic correlations between following milk and fertility traits have been investigated: duration of lactation DL, milk yield MY, milk fat content MFC, milk fat yield MFY, yield of 4% FCM, age at first calving AFC and duration of service period DSP. Results of the investigation of phenotypic correlations are obtained using mixed models LSMLMW (Harvey 1990). This method enables optimal consideration of numerous effects on investigated traits (bull sires, region, calving season, and calving year). Phenotypic correlation of traits in cattle breeding relates to presence of mutual positive or negative covariance which is result of the effect of genetic and factors of the environment. Information on phenotypic correlations between milk and fertility traits can be of great importance in selection of cows, since it provides possibility to choose/select heads based on several traits at the same time.

AB  - In this paper, results of the effect of direct and indirect selection of quantitative fertility traits of cattle end heritability level are presented. Study of the quantitative genetic parameters was carried out on three large farms of Black and White, Holstein-Friesian cattle. Investigation included 3900 first calving cows, daughters of 54 bull sires. The effect of genetic group of the head of cattle (genotype) and of the herd on fertility and milk traits of heifers and first calving cows of Black and White breed was investigated. Genetic group of the head of cattle (genotype) had no significant effect in variation of the fertility traits compared to general average (P (lt) 0.01). The effect of herd caused statistically significant and highly significant deviation from the general average, P  (lt)  0.05 and P  (lt)  0.01. Established heritability coefficients for fertility traits had low values for age at insemination (0,112), duration of pregnancy (0,045) and duration of service period (0,097). Results were obtained by applying mathematicalstatistical analysis of data - using mixed model (Harvey, 1990). Mathematical-statistical analysis of data was carried out using linear methods with fixed influence through model of Least Squares (LS method). Genotype of the head of cattle caused no significant deviation of fertility traits (P>0,05).

AB  - One of the important factors of successful milk production is group of secondary traits: health, longevity, type and milking traits. These traits have become increasingly significant. In order for productive life of cows used in production of milk to be as long and as successful as possible, special attention must be directed to traits of body type and constitution. In selection of cows into the category of bull dams all heads are measured - exterior traits, and evaluated linearly for traits of type or body frame, body muscular characteristics/muscularity, form (appearance) and udder according to Regulation on method of evaluation of traits of breeding livestock (Official journal of RS, No. 21,1996). The effects of rearing region and year of measuring, i.e. evaluating were analyzed in detail using the Least Squares Method (Harvey 1987). Average values of linear evaluations of investigated heads obtained by method of Least Squares were: body frame 7,85; muscularity 7,74; form 7,66; udder 7,62. The effect of region on linear evaluation was highly significant (P (lt) 0,01). Evaluation year also influenced highly significantly (P (lt) 0,01) obtained evaluation result for form, significantly (P (lt) 0,05) obtained evaluation result for body frame and muscularity, but no effect was established on evaluation result for udder.
AB  - Da bi produktivni život krava usmerenih za proizvodnju mleka bio što duži i uspešniji posebnu pažnju treba posvetiti osobinama tipa i konstitucije. Nedostaci u osobinama tipa dovode do slabije proizvodnje, lošeg zdravstvenog stanja i preranog isključenja krava iz stada. Uključivanje linearne ocene tipa u oceni priplodne vrednosti krava doprinosi pouzdanosti ocene priplodne vrednosti što se pozitivno odražava na ukupne efekte selekcije i uspešnosti proizvodnje. Pri izboru krava u kategoriju bikovskih majki sva grla su eksterijerno izmerene i linearno ocenjene za okvir, muskuloznost, formu (izgled) i vime u skladu sa Pravilnikom o načinu ispitivanja svojstava priplodne stoke (Službeni glasnik RS br. 21 iz 1996.godine). Na ispitivane linearne ocene detaljno su ispitani uticaji odgajivačkog područja i godine merenja, korišćenjem Metoda najmanjih kvadrata (Harvey 1987 ). Prosečne vrednosti linearne ocene ispitivanih grla dobijene metodom najmanjih kvadrata su: okvir grla 7,85; muskuloznost 7,74; forma 7,66; vime 7,62. Uticaj regiona na linearne ocene bio je vrlo značajan (P (lt) 0,01).

AB  - Investigation was carried out on three groups of kids of Domestic White breed and its crosses with Saanen breed: group of light, average body mass prior to slaughtering of 12,653 kg (8,8-15,0 kg) and average age of 70 days, group of medium heavy kids, average body mass prior to slaughtering of 17,613 kg (15,1-20,0 kg) and average age of 98 days and group of heavy kids, average body mass prior to slaughtering of 22,697 kg (20,1-25,7 kg) and average age of 129 days. Objective of our investigation was to determine body mass of kids prior to slaughtering which will ensure carcasses of acceptable commercial value in regard to carcass conformation, to which extent the carcass and kidneys are covered with fat tissue, color of meat and fat. It was established that heavier kids have more favorable evaluations for all observed traits of the carcass quality. Based on results obtained by investigation of the effect of body mass of kids prior to slaughtering on carcass measures and evaluation it can be concluded that heavier kids (15,1-25,7 kg) had better index of meatiness of carcass and thigh, better carcass conformation, the carcass and kidneys are better covered with fat tissue, the color of meat and fat are more favorable and as consequence the commercial value of such carcass is higher. Lighter kids (8,8-15,0 kg) have less superficial and kidney fat, therefore their meat is more suitable for specific restrictive nutrition.
AB  - Ispitivanja su izvedena na tri grupe jaradi domaće bele koze: grupa lakih prosečne telesne mase 12,653 kg (8,8-15,0 kg), srednje teških 17,613 kg (15,1- 20,0) i teških 22,697 kg (20,1-25,7 kg) i prosečnim uzrastom od 70,97, 98,41 i 129,00 dana. Cilj ovih ispitivanja bio je da se utvrdi koja težinska grupa jaradi ima najpovoljniju ocenu trupa (konformacija, prekrivenost masnim tkivom, boja mesa i loja). Utvrđeno je da su teža jarad povoljnije ocenjena u pogledu konformacije, prekrivenosti trupa i bubrega masnim tkivom, boje mesa i loja i marmoriranosti (zastupljenost masnog tkiva u mišiću) dok je struktura mesa bila povoljnija u lakših.

AB  - In three types of domestic animals: cattle, pigs and sheep, morphology of ovary was studied. Results such as differences in shape, size within and between species, number of follicles in maturation, changes in sex cycle, connection of follicles in maturation are presented in figures. By method of aspiration, oocytes were isolated from ovaries and their cytology analyzed as the first step in methods of in vitro maturation (IVM), followed by in vitro fertilization (IVF) and embryo transfer. These methods are wide spread in modern livestock production (cattle, horses) since they have many advantages of which the most important is to obtain more offspring from high quality female heads. Method has disadvantage: potential diminishing of biodiversity, therefore special attention is necessary in order not to endanger biodiversity and still get more offspring with high production abilities and traits. IVM, IVF and embryo transfer represent new approach to selection, fast and with similar effect like in conventional artificial insemination, therefore they should be applied in practice also in our country.
AB  - Kod tri vrste domaćih životinja: goveda, svinja i ovaca, izučavana je morfologija jajnika. Rezultati: razlika u obliku, veličini inter i intraspecies, broj folikula u zrenju, promene tokom polnog ciklusa, povezanost folikula u zrenju; prikazani su na slikama. Iz jajnika su metodom aspiracije iz jajnika izolovane jajne ćelije i analizirana njihova citologija kao prvi korak u metodi in vitro sazrevanja (IVM), nakon koje slede in vitro oplodnja (IVF) i embriotransfer. Ove metode su široko rasprostranjene u modernom stočarstvu (goveda, konji) jer imaju niz prednosti od kojih je najvažnije dobijanje većeg broja potomaka od kvalitetnih ženskih grla.

AB  - Investigation was carried out on the territory of Stara Planina mountain, Pirot mnucipality, in villages: Dojkinci, Brlog, Jelovica, Visočka Ržana and Rsovci, from 700-1200 m above sea level, on farms with greater number of sheep (over 100 heads) which in regard to the breeds structure were mainly Pirot pramenka breed, and insignificant number of heads were crosses of Pirot Pramenka and Württemberg. Research included analysis of pasture from the aspect of floristic and chemical composition. In regard to botanical composition it was concluded that grasses were present with approx. 50%, leguminous plants with 15% , and herbaceous plants with 35%. Share of crude protein in investigated samples varied from 4,81 to 13,57%, and of crude fibre from 20,67 to 37,17%. Yield of forage on pastures was from 0,6 to 2,0 t/ha. Low yield as well as unsatisfactory floristic composition of pastures resulted from poor care, especially lack of fertilization and their unplanned and inefficient use which was reflected on milk yield of sheep, in lactation of 180 days it was from 69,16-70,40 kg. Improvement of botanical composition can be achieved by application of fertilizers since in this way the share of useful grasses (Poaceae) and leguminous plants (Fabaceae) is increased, and share of herbaceous plants in total mass of pasture is reduced, which represents one of our goals in research on the Pirot territory of Stara Planina mountain. In order to preserve the quality and phytodiversity of plant species we suggested as optimal way of pasture utilization, combination of pasture and cutting system. In winter nutrition period, on investigated locations, introduction of haylage in nutrition of sheep used for production of milk is recommended, because of its higher nutritive value compared to hay.
AB  - U radu je analizirano sadašnje stanje u proizvodnji ovčijeg mleka (sa aspekta proizvodnje stočne hrane i ishrane) na području pirotskog dela Stare planine. Rezultati ispitivanja su pokazali da je postojeći sistem proizvodnje ekstenzivan i nezadovoljavajući obzirom na agrarno-geografski potencijal. U cilju prevazilaženja takvog stanja, naše aktivnosti su bile usmerene na uvođenje novih tehnoloških postupaka u ishrani ovaca kao što su: promena florističkog sastava pašnjaka pod uticajem đubrenja, planska eksploatacija pašnjaka i korišćenje senaže u ishrani ovaca za proizvodnju mleka.

AB  - Goat milk is biologically highly valuable protein food intended for nutrition of offspring and as raw material for preparation of different dairy products. Therefore, in our opinion, it was justified from zoo technical, genetical and economical aspect to direct our attention towards Serbian white diary goat and study basic traits of this breed. Based on our previous investigations of traits of Domestic white goat we have established that this was a domestic population of expressed hereditary milk traits and good quality of milk. This lead to more detailed study of the quality of milk obtained from the genotype called Serbian white goat in first lactation, created based on Domestic white goat, especially since there is great interest in breeding of this specific genotype on the territory of Serbia and also abroad. Based on performed investigations and established results it can be concluded that Serbian white goat belongs to the dairy goat type and is our best goat population. Regarding the quality of analyzed milk, in general it is of medium quality, however, the percentage of fat, proteins and lactose is very high, which is very important for dairy industry and further processing of milk into high quality goat cheeses which appear on our markets in very small quantities. Processing of goat milk into high quality cheese types is now performed in small number of mini dairy plants.
AB  - Kozije mleko je biološki visoko vredna belančevinasta hrana namenjena ishrani mladunčadi, kao i sirovina za spravljanje raznih mlečnih proizvoda. Stoga smo smatrali da je opravdano sa zootehničkog, genetskog, privrednog i ekonomskog gledišta, da se obrati što veća pažnja na srpsku belu mlečnu kozu i izuče njene osnovne rasne osobine. Na osnovu naših prethodnih ispitivanja osobina domaće bele koze utvrdili smo da se radi o domaćoj populaciji izraženih naslednih osobina za mlečnost i dobar kvalitet mleka. To nas je navelo da se usmerimo na detaljnije izučavanje kvaliteta mleka novonastalog genotipa nazvanog Srpska bela koza u I laktaciji, a nastao na bazi Domaće bele koze. Ovo utoliko pre što za njeno gajenje već postoji velika zainteresovanost na području Srbije pa i šire. Na osnovu sprovedenih ispitivanja i utvrđenih rezultata može se reći da Srpska bela koza pripada mlečnom tipu koza i predstavlja našu najbolju populaciju. Što se tiče kvaliteta analiziranog mleka ukupno posmatrano je osrednje vrednosti, međutim, treba istaći izražen procenat masti, proteina i laktoze, što je veoma bitno za industriju mleka i dalju preradu u kvalitetne sireve, a na našem tržištu se pojavljuje u malim serijama. Prerada kozijeg mleka u kvalitetne neke tipove sireva za sada se obavlja u veoma malom broju mini mlekara zanatskog tipa.

AB  - Body development and production capacity in dairy production are in relation. However, body development, i.e. exterior of cows doesn’t define its functionality which is manifested in production of milk. Therefore, the capacity of cow to produce milk can only be determined more precisely by direct measuring of the production. Visual evaluation of body development and way to recognize the characteristics of dairy cows are initial parameters of milk traits, partially also longevity, as well as reproductive traits of the head of cattle, which is important from many aspects of the economical efficiency in dairy production. Exterior measures taken when cows were selected to be included in herd of bull dams, and which are also subject of this research, are following: height of withers, carcass length, breast depth, breast girth, body weight. For all investigated traits basic variation-statistical parameters were calculated: arithmetic mean value, standard deviation, coefficients of variation, standard error, variation interval. Average values of exterior measures obtained in this research were following: height to withers 136.29 cm, carcass length 165.50 cm, breast depth 72.97 cm, breast girth 200.07 cm, body weight 686.27 kg. Based on presented data it can be concluded that traits of body development of Simmental bull dams are above the average values determined for controlled population, which further justifies our conclusion that bull dams are "top" heads of cattle of the main herd.

AB  - To analyze variability and heritability of body development traits and possibilities for their improvement data of 371 performance tested Simmental bulls were used. Average test-on (120 days of age) and test-off (365 days of age) height at withers (HW), circumference of chest (Cir), depth of chest (DC), width of round (WR), width of hip (WH) and body length (BL) were 99.88±3.49 and 126.00±2.65 cm, 127.42±6.14 and 184.76±5.95 cm, 42.55±2.25 and 60.90±2.15 cm, 32.56±3.01 and 47.63±2.67 cm, 30.26±2.12 and 44.14±1.93, 106.69±5.99 and 147.57±4.65 cm, respectively. Average values for test-on and test-off index of body frame (IBF), index of chest depth (ICD), index of body compactness (ICBL), and index of massiveness (IM) were 106.8±4.44 and 117.13±3.11%, 42.61±1.90 and 48.34±1.45%, 119.59±5.19 and 125.27±4.26%, 127.58±4.86 and 146.65±4.30%, respectively. Heritability estimates for test-off height at withers, circumference of chest, depth of chest and body length were 0.43, 0.30, 0.33 and 0.29. Possibilities for improvement of body development traits were done according to their phenotypic and genetic variability. Obtained results confirm that exist enough variability in major body development traits in Simmental bulls which can be utilized not only for genetic improvement of milk production in their daughter, but also for improvement of overall body traits in Simmental population in Serbia.

AB  - This paper is based on investigation of chemical and hygiene parameters of the quality of cow raw milk. Samples were collected on 10 collection spots of the dairy firm "Imlek", in 4 identical time intervals in the period of one month (20.06.2005.-20.07.2005.) in municipality of Gornji Milanovac, and research was carried out in the laboratory of "Imlek" in Čačak. Differences in chemical composition and hygienic quality of milk were analyzed, and slight variability was established between collection spots. Average content of milk fat was 3,89%, protein 3,20%, and dry matter without fat 8,56%. It was established that in regard to protein content there is significant and very significant statistical difference between collection spots. This is consequence of different nutrition, focus is on introduction of protein enriched feeds into nutrition of cows. High variability of number of micro organisms is consequence of inadequate, non-standardized obtaining (milking) and storing of raw milk. Average number of micro-organisms was 844.875/ml, and it varied from 112.000–5.000.000/ml. Average somatic cell count was 357.850/ml. Variance analysis determined that collection spots had statistically highly significant effect (P (lt) 0.01) only on protein content, whereas their influence on content of fat, dry matter without fat, number of microorganisms and somatic cell count wasn't significant (P>0.05). Individual testing (LSD test) established that milk collected from 7th collection spot had significantly higher protein content compared to other collection spots, which indicated that dairy heads of cattle consumed higher quantity of feeds rich on proteins and had better balanced diet in regard to ratio of energy and protein.
AB  - Rad je zasnovan na ispitivanju hemijskih i higijenskih parametara kvaliteta sirovog mleka. Uzimanje uzoraka je vršeno na 10 "Imlek"-ovih sabirnih mesta u 4 jednaka vremenska razmaka u periodu od mesec dana (20.06.2005.-20.07.2005.godine) u opštini Gornji Milanovac, a ispitivanje je izvršeno u laboratoriji "Imlek"-a u Čačku. Analizirane su razlike u hemijskom sastavu i higijenskom kvalitetu mleka, pri čemu su utvrđene male varijabilnosti između sabirnih mesta. Prosečan sadržaj mlečne masti iznosio je 3,89%, proteina 3,20%, a suve materije bez masti 8,56%. Utvrđeno je da kod sadržaja proteina postoji značajna i vrlo značajna statistička razlika između sabirnih mesta. To je posledica različite ishrane, pri čemu se daje akcenat na uvođenje u ishranu proteinski bogatih hraniva. Ispitivanje hemijskog sastava i mikrobiološke ispravnosti, koje je vršeno kod proizvođača AD "Imlek"-a, pokazalo je izvestan pomak u poboljšavanju higijenskog kvaliteta sirovog mleka. Visoka varijabilnost kod broja mikroorganizama posledica je neadekvatnog, nestandardizovanog dobijanja (muže) i čuvanja sirovog mleka. Prosečan broj mikroorganizama je iznosio 844.875/ml, a kretao se od 112.000-5.000.000/ml. Prosečan broj somatskih ćelija je 357.850/ml.
