An experiment was conducted to examine the effects of oxalate intake on calcium and phosphorus balance in bulls fed Napier silage. Eighteen growing having average live weight 249 ± 8.38 Kg aged about 40 months were divided into three groups six animals each group. They assigned dietary treatments T0 (considered as control), T1 T2 consisting rice straw, straw silage (1:1, DM basis) ad libitum, respectively for a period 21 days. A concentrate mixture composed 940 g wheat bran, 60g dicalcium...

The study was conducted to investigate nutrient metabolism and semen quality of bulls fed with moringa ( Moringa oleifera ) leaves, twigs, branches as a major concentrate ingredient. Twenty-one Red Chittagong about 204 (±50) kg initial live weight (LW) were randomly divided into three equal LW groups. They maize silage basal feedstuff for 65 days the supplementation mixtures at 1% LW, consisting either 0, 25, or 50% mash on fresh basis. sun-dried ground preparation moringa. results indicated...
