In dairy cattle, quantitative trait nucleotides (QTNs) underlying quantitative trait loci (QTL) for milk production traits have been identified in bovine DGAT1, GHR and ABCG2 genes. The SPP1 gene has also been proposed to be a regulator of lactation. In sheep, QTL underlying milk production traits have been reported only recently, and no proven QTN has been identified. Taking into account the c...

Nowadays, the quality of any food used for human consumption is, to a considerable extent, considered by its possible contribution to the maintenance or improvement of the consumer's health. In developed countries there is increasing interest in goat milk and its derivates, the quality of which is considered of special importance in the light of current tendencies favouring healthy eating. In p...

This study was aimed at determining the presence of C. burnetii in cattle and sheep herds in the Kars region of Turkey using serological and molecular methods. As a serological technique, C.burnetii IgG in blood sera and milk samples were investigated with ELISA. The results of these examinations revealed that 108 (43.2%) out of 250 sheep blood serum samples and 52 (14.85%) out of 350 cattle bl...

The natural creaming of raw and heated camel milk was studied. Compared with cow (Bos taurus) milk, camel (Camelus dromedarius) milk showed very slow creaming rate in both raw and heated milk at refrigerator and room temperatures. Fat globule size distribution was similar in cow and camel milks. The creaming ability was also studied in various combinations of skim milks and creams of raw camel ...

Previous studies demonstrated that milk yields in sheep displaying strong seasonal sexual activity depend on the day length. The objective of the studies was to determine whether the introduction of melatonin in high pregnancy affects milk secretion in seasonally sheep. The studies were carried out on 60 Polish Longwool sheep. Sheep were allocated to three groups: Group I (n=20 – the control gr...

Brun., 2011, LIX, No. 3, pp. 209–214 The aim of this study was to compare the sensitivity to selected antibiotics in staphylococci isolated from goat (n = 60), sheep (n = 60) and cow’s milk (n = 120). T...

Raw milk is a valuable food which its quality is important regarding both milk consumption itself and manufacturing of other dairy products. The aim of this study was to investigate the effect of different seasons on the variations of raw milk composition. To do so different samples of raw milk were taken during summer and winter from Qazvin province and their physicochemical properties includi...
