Toxic effects of Aflatoxin B1 on growth performance and humoral immune response against Newcastle disease Virus (NDV) vaccine were determined in Japanese quails. Quail chicks (n=300) were divided into five groups and each group was further sub-divided into two subgroups. One subgroup of each group was vaccinated with NDV vaccine to study the antibody response. Experimental diets were prepared b...

The addition of Daka Porcine Plasma or 2,500 ppm zinc prescribed by the vet significantly increased the pigs’ production value. The highest production value (+9%) was obtained by adding both Daka Porcine Plasma and 2,500 ppm zinc to diet 1 (the diet given the first 14 days post-weaning). A significant positive effect was obtained on daily gain and feed intake before intermediate weighing (10 da...

The treatments were as follows: 1) basal diet formulated to meet all nutritional requirement of calves according to NRC (20...

There are many studies on the effects of probiotics on performance of broiler chickens, but none of them has evaluated the metabolizable energy (ME) equivalency values of probiotics. The aim of this study was to determine the metabolizable energy equivalency value of Bacillus subtilis spore and its potential for decreasing feed ME content and cost. One hundred seventy-six day-old male broilers ...
