AB  - Two genotype of sheep have been utilized in the conduct of the experiment composed of 60 ewes from Pirot x Virtemberg as genotype 1 and 60 ewes of Improved Pirot as genotype 2. All the ewes were reared under identical conditions and without any differences in nutrition and management during the whole period under study. The collection of Milk sampling was done in morning and evening during periods (1, 2, 3) of lactation duration. The average lactation duration and average total milk of the two genotypes were very close and has a minimal difference of 0.467 day and 1.562 kg, in favor of genotype 2. The differences between genotypes were not significant (P>0,05). Regarding physical and chemical properties of milk for both genotypes, the difference were very minimal such as follows; viscosity Pa x s - 0.006, electrical conductivity Ω - 0.018, density kg/m3 -0,001, freezing, t 0C - 0.013, LD number - 0.028 total solids, % - 0.014, fat,% - 0,026, protein,% - 0.085, lactose,% - 0.038, ash,% - 0,021, acidity, 0SH - 0.209. The results indicated that the properties of milk for both genotypes were very near to each other. It can be interpreted that the breeds utilized in the experiment were comparable due to similar characteristics perhaps. The effect of genotype was very significant only for the % protein of the milk. The lactation periods were highly significant in all physical and chemical properties of milk.

AB  - Estrus synchronization methods was use to control the reproductive traits of sheep, as well as bringing more females at the same stage of estrus and ovulation. According to the points mentioned above, the aim of the present study was to investigate and compare mating method and influence of fixed factors on birth and weaning weight of lambs. Statistical analysis showed that exist difference in the body weights between genotypes of lambs. In the first group, the difference in weight of lambs at birth, regardless of mating method was not significant (P> 0.05), while in the second group, the difference was slightly significant (P  (lt) 0.05). As for the birth type, sex and within the same genotype, there was a statistical significance (P  (lt) 0.05) between singles obtained naturally, between the triplets obtained naturally and between triplets received hormonal method. All the differences between body weight at 30 days (mating method, sex and birth type under the same genotype) were statistically significant (P  (lt) 0.05).The determined differences in the body weights at 60 days (sex, mating method and type of birth under the same genotype) were statistically significant (P  (lt) 0.05). The results showed that the differences (mating method, sex and type of birth under the same genotype) were statistically significant (P  (lt) 0.05), except in between body weight at 90 days in twins among two genotypes obtained by natural method, which were not statistically significant (P> 0.05).

AB  - The paper presents the results of a research on the impact of products based on natural zeolite on the production results of fattening lambs. The experiment involved two groups of lambs (the control - C and experimental - E groups), each consisting of 15 heads, for a period of 90 days. The meal was made from sheep milk, feed mixtures for fattening lambs and meadow hay. The test group lambs, unlike the ones from the control group, were given mixtures based on natural zeolite. Min-a-Zel S mixture (in the form of 25% composite) was fed to lambs from birth till their 14th day of life, directly into the mouth, once a day (before the morning feed), in the amount of 10 ml. Min-a-Zel Plus was given to them from their 15th day of life, together with the feed mixture (0.5%). Feeding was at will. The average weight of lambs at the end of the experiment, in accordance with the sequence of treatments (C:E) was 24.40:26.94 kg (P  (lt) 0.01). Daily weight gain of lambs, during the experiment, was 229:256 g and in the experimental group it was by 27g or 11.79% higher (P  (lt) 0.01). The test group lambs had a better utilization of dry matter, protein and energy, which justifies the use of products based on natural zeolite in fattening lambs.

AB  - Milk yield and milk chemical composition are largely affected by the quality of dairy cattle diet. The chemical composition of milk is dependent upon a large number of factors, including breed, diet, care, housing system, stage of lactation, etc. Milk composition is primarily a breed-specific trait. This study was conducted over a period of 15 months, involving Serbian Spotted dairy cattle. The experimental animals were assigned to three groups, each receiving different levels of supplemental zeolite. The control group comprised cows that received no zeolite supplement. Experimental Groups I and II were fed compound feeds supplemented with 4% and 2% zeolite, respectively. Milk samples were analysed for the contents of milk fat, proteins, fat-free solids and lactose, and density. The results obtained suggest that zeolite supplementation affects milk chemical composition, depending on the zeolite level present in livestock feed.
AB  - Najveći sadržaj mlečne masti u mleku je izmeren kod krava I-O grupe 4,62%, zatim kod K-grupe 4,28% i najmanji kod II-O grupe 4,26%. Statistički signifikantnih razlika u sadržaju mlečne masti među grupama je bilo (P (lt) 0,05). Nivo proteina u mleku krava bio je u intervalu od 3,34% kod krava II-O grupe do 3,51% kod krava kontrolne grupe. Krave K-grupe imaju najveći prosečni sadržaj proteina u mleku ali i najveće varijacije u ovoj osobini. Na osnovu sadržaja proteina u mleku statistički značajnih razlika između grupa nije bilo (P>0,05). Prosečne vrednosti gustine mleka bile su u opsegu od 31,21% kod krava IIO grupe do 33,00% kod krava K-grupe. Kao i kod prethodne osobine i ovde je najmanja prosečna vrednost merene osobine bila kod krava II-O grupe (31,21), sa isto tako, najmanjim koeficijentom varijacije među grupama (3,01). Kod ove osobine uočene su statistički značajne razlike među grupama (P (lt) 0,05). Najveći sadržaj SMBM u mleku imale su krave K-grupe sa iznosom od 9,56%, a najmanju krave II-O grupe 9,11%. Najveće variranje ove osobine je kod krava K-grupe, a najmanje kod krava I-O grupe sa iznosom od 2,51%. Sadržaj SMBM u mleku pokazao je statistički značajne razlike (P (lt) 0,05). Sadržaj laktoze u mleku krava bio je u intervalu od 5,01% kod krava II-O grupe do 5,26% kod krava K-grupe. Krave I-O grupe imale su količinu laktoze koja se nalazila između ove dve grupe. Sadržaj laktoze u mleku krava između grupa pokazao je statistički značajne razlike (P (lt) 0,05). Dodavanje zeolita ('Tufozel') imalo je uticaja na hemijski sastav mleka kod ispitivanih krava muzara.

AB  - Milk yield and milk chemical composition are largely affected by diet quality. Natural zeolite has been successfully used in livestock production as a feed supplement for some types and categories of domestic animals. This experiment was conducted over a period of 15 months involving Domestic Spotted dairy cattle. The test animals were assigned to three groups, each receiving different levels of supplemental zeolite. The control group comprised cows that received no zeolite supplement. Experimental groups I and II were fed compound feeds supplemented with 4% and 2% zeolite, respectively. The production traits studied included the following milk performance traits: whole lactation length, milk and fat yields over whole lactations, milk and fat yields over standard lactations. The results obtained suggest that zeolite supplementation affects some production traits, depending on the zeolite level present in livestock feed.
AB  - Kontrolna grupa krava imala je prosečno trajanje laktacije od 312 dana, sa varijacijama od 300 do 360 dana. Ova grupa se po dobijenim rezultatima nalazi između ostale dve grupe krava. Statističke razlike u trajanju celih laktacija među grupama su značajne (P (lt) 0,05). Najniža proizvodnja mleka u celim laktacijama zabeležena je kod krava Kgrupe (6395,20 kg), viša kod krava I-O grupe (6714,13 kg) i najviša kod krava II-O grupe (6934,13 kg) koja je dobijala 2% zeolita preko krmnih smeša. Statističke razlike u proizvodnji mleka u celim laktacijama među grupama su vrlo značajne (P (lt) 0,01). Najmanja prosečna produkcija mleka zabeležena je kod krava K-grupe (6342,33 kg). Znatno veća proizvodnja je bila kod krava koje su dobijale zeolit. Krave I-O grupe dobijale su 4% zeolita i postigle su prosečnu mlečnost od 6690.86 kg. Krave II-O grupe dobijale su 2% zeolita i postigle su najveću prosečnu mlečnost od 6711.80 kg. Krave II-O grupe imale su najveću prosečnu proizvodnju mleka u standardnim laktacijama i najniži koeficijent varijacije među grupama. Statističke razlike u proizvodnji mleka u standardnim laktacijama među grupama su vrlo značajne (P (lt) 0,01). Krave K-grupe imale su najmanju prosečnu priozvodnju mlečne masti u mleku, a krave II-O grupe najveću. Statističke razlike u količini mlečne masti u celim laktacijama među grupama su vrlo značajne (P (lt) 0,01). Takođe su vrlo značajne (P (lt) 0,01) i statističke razlike među grupama u količini mlečne masti u standardnim laktacijama.
