Özet
The effects of breed and period of lactation on milk composition were investigated. For this purpose, 8 crossbred (3/4 German fawn 1/4 Hair goat) and 10 Damascus goats were kept under identical management conditions. Lactation period affected milk yield and milk composition in both goat breeds. Milk yield, lactation duration, and mean solid and fat values showed differences between the breeds. The mean values of total solid and fat of milk during lactation were 13.82 +/- 0.294% and 4.55 +/- 0.223% for the crossbreds, and 12.90 +/- 0.179% and 4.02 +/- 0.142% for Damascus goats, respectively. Although the percentages of short-chain free fatty acids (FFAs) (C-4 to C-8) in the milk of both breeds did not change during lactation, the other FFAs (C-10-C-18:3) significantly varied (P <= 0.05, P <= 0.01). The results showed that hexadecanoic (C-16), 9-octadecenoic (C-18:1), octadecanoic (C-18.), tetradecanoic (C-14)()), decanoic (C-10), and decanoic (C-12) FFAs were the most predominant FFAs in the milk of both breeds from March through September, but octadecanoic acid and tetradecanoic acid shifted during the last 2 months of lactation.
