The effect of protected soybean groats and lemuru fish oil supplementation in ration on performance of Ongole crossbred cows

This study aims to determine the effect of protected soybean groats and lemuru fish oil as feed supplement on the performance of Ongole crossbred cows at postpartum periods. The treatments were P1 = 90 basal feed + 10 unprotected soybean groats and lemuru fish oil mixture; P2 = 90 basal feed + 5 unprotected soybean groats and lemuru fish oil mixture + 5 protected soybean groats and lemuru fish oil mixture; P3 = 90 basal feed + 10 protected soybean groats and lemuru fish oil mixture. Birth weight of calves at P1, P2, and P3 treatments were 26.00, 31.60, and 28.40 kg, respectively. The results of the variance analysis showed that the use of soybean groats protected lemuru fish oil in rations significantly affected the daily weight gain of calves but did not affect the daily weight gain of cows as well as feed conversion and efficiency. The conclusion of this study was that the use of 5 protected soybean groats and lemuru fish oil mixture combined with 5 unprotected soybean groats protection and lemuru fish oil mixture in ration of Ongole crossbred cow able to increased birth weight and average daily gain of calves.
