- Abstract
Sixteen multiparous crossbred cows and Sixteen Murrah buffaloes (Bos Bubalis) in their early stage of lactation were randomly divided into four groups (Groups I and II for cows and groups III and IV for buffaloes). Animals of groups I and III were offered daily ad lib. berseem fodder (Trifolium alexandrinum) and wheat straw and similarly animals of groups II and IV were offered ad lib concentrate mixture and wheat straw ad lib. for 12 weeks experimental period. After adaptation (4 weeks), the milk samples collected at fortnight intervals were analyzed for milk fat, solid not fat (SNF), total solids and milk protein. Milk sample (100 ml) from each animal of all the four groups was collected from each milking at fortnightly interval and pooled for fatty acid analysis including CLA. Ghee (clarified butter oil) was also prepared at fortnight intervals by indigenous and creamy (commercial) methods from the total milk collected of each group. The milk yield in four respective groups averaged 12.06, 11.93, 9.99 and 7.80 kg/day, increased (P<0.01) in group III where buffaloes fed berseem forage diet as compared to concentrate diet, while there was no effect in cows. Total milk fat, protein, total solids and SNF were not affected by dietary treatments in both cows and buffaloes. Total CLA content in milk averaged 19.55, 6.44, 16.38 and 6.78 mg/g fat in four respective groups, recorded higher (P<0.01) in berseem fed groups of both the species. In cows, total CLA content increased two folds in ghee prepared by indigenous method in two different fed groups i.e. 10.40 vs 20.07 (group 1), 6.93 vs 12.13 (group II), whereas, it increased by 40-50% in buffaloes (10.38 vs 16.87 in group III and 5.83 vs 7.59 mg/g in group IV). Feeding of fresh forage to the animals along with indigenous method of ghee preparation resulted in 310% increase in CLA content.
