Ninety Starbro broilers of one month age having
an initial live weight 1150-1320 g for 15 days (finisher period) were
randomly assigned to six treatment which were fed on different levels
of soybean oil. In the finisher period (30th to 45th day), total live
weight gain of the broilers fed 4% (920 g) and 6% (961 g) soybean oil
diet were significantly higher than the broilers fed 0 (764 g), 2 (870
g), 8 (867 g) and 10% (782 g) soybean oil diets. Total feed intake was
gradually decreased with increasing levels of soybean oil in the diets.
Feed conversion efficiency (FCE) was gradually improved with increasing
levels up to 6% of soybean oil and then decreased with above the levels
(e.g. 8 and 10%) of soybean oil in the diets. Similarly, the cost benefit
ratio (CBR) of T2 (2.15) and T3 (2.17) groups
were significantly more satisfactory than the other treatment groups
(T0 = 1.92, T1 = 2.09, T4 = 1.97 and
T5 = 1.72). So, up to 6% soybean oil may be added in the
broiler finisher diet during hot weather in Bangladesh. |

A comparative study on productive and reproductive performance of crossbred and indigenous cows under the small holder dairying condition was conducted in Gaibandha district of Bangladesh. A sample of 96 dairy cows were selected randomly; of which 49 were crossbred cows and the other 47 were indigenous dairy cows from 50 small dairy farms. The productive performance (milk yield and lactation period) of crossbred cows were significantly (P=0.01) higher than the indigenous dairy cows. Post partum heat period, calving to first service and dry period of the indigenous cows were lower (but not significantly) than crossbred cows. But service per conception and calving interval of indigenous cows were significantly (P=0.01) lower than the crossbred cows. The cost benefit ratio of raising crossbred and indigenous dairy cows were 1:1.13 and 1:1.02 respectively. Although, reproductive performance of crossbred cows were better than indigenous cows but considering the other traits it may be concluded that the raising of crossbred cows were more economic than the raising of indigenous dairy cows. |

A study was conducted in a typical village to evaluate the effect of pre and postpartum supplementation (UMMB) of indigenous cows on the performance of their calves. Thirty-two cows were supplemented with UMMB from 6 months of prepartum to 6 months of postpartum period and 30 cows were fed only traditional feed (without UMMB) . The cows were milked once a day in the morning. The calves were tied up at the night and allowed to free access or suckling to the dams during the whole day. The birth weight of the calves in supplemented (UMMB) group (14.61 kg) was significantly (P=0.05) higher than the control group (12.00 kg). Similarly, live weight gain of supplemented calves was also significantly (P=0.01) effected by the cows supplemented with UMMB (117 g/d) than the cows without UMMB (56 g/d). The mortality was 9% in control group whereas no calf did not died during the experimental period. So, it can be concluded that supplementation to pre and postpartum cows with UMMB can have better effect on the performance of their calves.

An experiment was conducted over a 56 days period with 60 New zealand white crossbred post weaned young rabbits aged about 4 -5 weeks having an initial average live weight of 418-438 g whose mothers fed diets containing 13.17, 16.64 and 21.00% CP. The young rabbits were fed concentrate diets containing 16.64% CP along with ad libitum green grass (Hymenachne pseudointerrupta). According to their mother diets, they were assigned into 3 experimental groups (A, B & C) The average dry matter intake was significantly (P<0.01) higher in the rabbits of group B than group A & C. Live weight gain was significantly (P<0.01) higher in group C (16.6 g/day) than group A (8.7 g/day) and B (14.6 g/day). The young rabbits of group C converted feed to meat more efficiently than group A & B. So, it may be suggested that for better post weaned litter performance, concentrate mixtures containing 21.00% CP diet along with ad libitum green grass may be provided to rabbit does during their pregnancy and weaning period under tropical conditions. |
