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  - Fiziološka istraživanja su obavljena na eksperimentalnoj farmi ovaca Instituta za stočarstvo Beograd-Zemun. Ogledom je bilo obuhvaćeno 18 muške jagnjadi meleza F1 generacije : pirotska pramenka x virtemberg x Ile de France, prosečne telesne mase oko 35,0 kg, raspoređenih u tri grupe. Ishrambeni tretman je podrazumevao ispitivanje efekata različitih nivoa na svarljivost hranljivih materija. Dobijeni podaci su obrađeni standardnom statističkom analizom. Prosečni koeficijenti svarljivosti ukupnih proteina kod jagnjadi na tretmanima I:II:III su iznosili: 52,58% : 51,30% : 55,12%; masti: 76,13: 77,98: 87,17%; celuloze: 67,40 : 45,87: 22,39% i BEM-a: 83,87 : 76,05 : 82,96%. Ova istraživanja su pokazala da su sa aspekta svarljivosti hranljivih materija, najpovoljnije rezultate ostvarila jagnjad na tretmanu sa 58% nerazgradivog proteina.

AB  - Investigations were carried out on 60 suckling lambs (24 males and 36 female lambs) - R2 generation obtained by crossing Pirot Pramenka with Württemberg rams, divided into 3 groups. At the beginning of the trial lambs were 30 days old with average body mass of 15 kg. Animals were fed ad libitum alfalfa hay and iso-protein mixtures (16% total protein) with different energy content. Energy value of used mixtures was 7.29 (I), 7.71 (II) and 7.94 MJ NEM (III). Trial lasted 60 days. Following production parameters were monitored: body mass, average daily gain, feed and nutrient consumption and conversion, depending on the applied feeding treatment. Statistical processing of obtained data was carried out on PC, using variance analysis. Final body masses of lambs (age of 90 days) were: 29.81 kg (I), 31.19kg (II) and 29.86 kg (III). Average daily gain for entire fattening period according to treatments I: II: III was 0.280kg: 0.303kg: 0.277kg. Values of DM conversion (kg/kg) for trial groups I:II:III were 2.68: 2.58: 2.93. Utilization of energy (MJ/kg) in average was 19.45: 18.98: 21.64, whereas the conversion of total protein (g/kg) according to the same order of treatments was 481: 451: 514. Performed research has shown that certain advantage can be attributed to lambs fed fodder mixture II (16% of total protein and 7.71 MJ NME), considering that they have realized the highest gain and the lowest use of feed and nutrients as well as energy.

AB  - Based on results of performed investigations and analysis of existing conditions relating to technological process in production of kachkaval, we propose the following: To determine the causes of disturbed secretion in case of cows and sheep, investigate the mechanism of proteolytic activity and explain the origin (endogenous or exogenous); Goat milk should be delivered to dairies separately; control of temperature and relative humidity in departments for maturing and drying of cheese; introduction of whey and water separation; in that case, butter can be produced from separated cream. In order to successfully realize project it is also necessary to investigate location of the dairy in Dojkinci in relation to raw material status in different seasons of the year, and take certain measures for improvement of hygienic condition of milk throughout entire technological process: milking, delivering to dairies, storage, transport, etc.; obligatory introduction of basic routine milk analysis when delivered to dairies (volume, acidity, etc.); Introduction of technological log - diary for certain phases of production of kachkaval is also necessary. Finally, subsequent to standardization of entire technological process activities related to obtaining of brand name for such product with determined geographical origin are of great importance.

AB  - Development of the improvement theory, improvement of the technological process of production, especially greater demand for high quality lamb sheep milk cheeses (yellow hard cheese, white soft cheese) and wool of improved traits, demands modernization of organizational forms of selection in sheep production. Activities of people engaged in selection are concentrated on several directions focusing on the defining the organizational scheme based on the fact that mass selection which is most frequent in sheep production, could be more efficient with adequate organization. The opinion is prevailing that the best way of organizing is according to the principle of pyramid. Selection procedure within the pyramid is question of agreement between the genetic scientist and farmer depending on the improvement objective. Beside this pyramid organization, in countries with advanced stage of sheep production, other selection programs are present which represent not replacement of the pyramid organization but are expression of the will to better determine the economical parameters and increase, the fanner's profit Special attention in sheep selection is directed towards the providing of unique scientific approach to the evaluation of the animal based on objective productivity control. Software is developed for more efficient realization of the selection procedure and genetic information systems introduced on relation farmer - selection service.
AB  - U ovom preglednom radu su izneti savremeni trendovi u organizaciji selekcije u ovčarstvu po smerovima proizvodnje. Povećanje interesa za ovčijim mesom zahteva usavršavanje postojećih I primenu novih organizacionih formi selekcijskih postupaka. Razvojem kompjuterske tehnike, razrađeni su praktični korisnički softveri za efikasnije sprovođenje selekcijske procedure. U cilju smanjenja troškova merenja i povećanja efikasnoti selekcije ovaca na mesnatost, organizuju se kooperativne odgajivačke strukture farmer a. Proizvodnja mleka u određenoj populaciji se može povećavati iz godine u godinu, ukoliko se selekcija sprovodi putem grupnog oplemenjivanja, na principu piramide koja se sastoji iz nukleusa i komercijalnog stada. Princip organizacione seme selekcije u cilju povećanja prinosa i kvaliteta vune takođe ba- zira na osnovnim postavkama tradicionalne piramide. Pri tome se unapred postavlja željeni odgajivački cilj i predviđaju efekti selekcije.

abstract = "Development of the improvement theory, improvement of the technological process of production, especially greater demand for high quality lamb sheep milk cheeses (yellow hard cheese, white soft cheese) and wool of improved traits, demands modernization of organizational forms of selection in sheep production. Activities of people engaged in selection are concentrated on several directions focusing on the defining the organizational scheme based on the fact that mass selection which is most frequent in sheep production, could be more efficient with adequate organization. The opinion is prevailing that the best way of organizing is according to the principle of pyramid. Selection procedure within the pyramid is question of agreement between the genetic scientist and farmer depending on the improvement objective. Beside this pyramid organization, in countries with advanced stage of sheep production, other selection programs are present which represent not replacement of the pyramid organization but are expression of the will to better determine the economical parameters and increase, the fanner's profit Special attention in sheep selection is directed towards the providing of unique scientific approach to the evaluation of the animal based on objective productivity control. Software is developed for more efficient realization of the selection procedure and genetic information systems introduced on relation farmer - selection service., U ovom preglednom radu su izneti savremeni trendovi u organizaciji selekcije u ovčarstvu po smerovima proizvodnje. Povećanje interesa za ovčijim mesom zahteva usavršavanje postojećih I primenu novih organizacionih formi selekcijskih postupaka. Razvojem kompjuterske tehnike, razrađeni su praktični korisnički softveri za efikasnije sprovođenje selekcijske procedure. U cilju smanjenja troškova merenja i povećanja efikasnoti selekcije ovaca na mesnatost, organizuju se kooperativne odgajivačke strukture farmer a. Proizvodnja mleka u određenoj populaciji se može povećavati iz godine u godinu, ukoliko se selekcija sprovodi putem grupnog oplemenjivanja, na principu piramide koja se sastoji iz nukleusa i komercijalnog stada. Princip organizacione seme selekcije u cilju povećanja prinosa i kvaliteta vune takođe ba- zira na osnovnim postavkama tradicionalne piramide. Pri tome se unapred postavlja željeni odgajivački cilj i predviđaju efekti selekcije.",

AB  - Selection of sheep according to milk yield is increasingly present especially in Mediterranean countries due to production of high quality cheeses, for instance hard cheese. This demands knowledge of genetic parameters of milk yield traits, as well as of the effect of paragenetic factors. Investigation of these paragenctic factors was objective of this paper. Investigations were carried out in the region of Stara planina mountain on population of Pirot Pramenka sheep breed. The effect of year, lactation, type of birth and number of offspring on milk yield was investigated. It was established that the effect of year as paragenetic factor varied from not significant to significant. Lactation had significant effect on milk yield since the lowest value for the milk quantity was registered in the first and the highest in third lactation. Type of birth had no significant influence on investigated trait. The size of litter had significant influence on milk yield since higher quantity of milk was established in case of sheep with twins compared to ship with single offspring.
AB  - U radu su ispitivani uticaji najvažnijih faktora paragenetske prirode na mlečnost ovaca pirotske pramenke na području Stare planine. Rezultati istraživanja su pokazali da postoje pozitivna i negativna odstupanja u mlečnosti zavisno od godine ispitivanja, laktacije po redu, tipa rođenja i veličine legla. Ako se prihvati procena da faktori spoljne prirode imaju odlučujući uticaj u proizvodnji mleka, onda rezultati do kojih se došlo mogu biti pokazatelj za efikasnije projektovanje oplemenjivačkih programa i proizvodnje u celini.

AB  - Increase of the production of lamb meat can be achieved by increasing the number of twin lambs which is popular practice in the world today - forcing of the multiple fertility. However, the issue of early weaning of Iambs is also present in many cases. It is known that twins are more difficult to maintain during first period and they are slower in growth in future development, which indicates the production of early weaned twin lambs. In domestic, and especially international, literature the issue of early weaning of twin lambs from the aspect of production of lamb meat was discussed however there are no literature references regarding the effect of early weaning on future development of twins after weaning. The objective of this paper was to determine the effect of early weaning of twins on their future development and production, and breeding. Based on presented analysis regarding the effect of early weaning of twin lambs on their future development and production, the following can be concluded: Early weaned twins (age of 2 months) have slower growth and body development compared to single offspring but these differences weren't statistically significant. However, although technically more complicated, weaning of twins only several days after birth was proved to be most efficient in regard to future development and production since these twins were the only ones which have realized same results as single lambs during the investigation period. In case of early weaning, growth of twin lambs depends on their initial body mass which is almost always below the body mass of single lambs. The wool production was higher in case of those animals whose body was more developed, that is the skin surface larger, also the nutrition during first two months was unified and regular as in case of single lambs and lambs from group I.

AB  - Livestock husbandry participation in total agriculture production of Serbia is unfavorable (41% of total value). Sheep and goat breeding particularly lag behind. Sheep production participate with extremely low percent in total world production in this branch. Sheep and goat breeding importance was declining for a long period of time. An increase of interest for sheep breeding was noticed in early nineties since it was more resistant to the economy hardships than pig and poultry production. Concerning the natural conditions, cultural heritage and other social aspects, regional and geo-strategy importance of this production, we consider this increase of interests for sheep and goat breeding necessary to support.
