JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES Abstract The experiment was conducted on broiler chicks to evaluate the effects of enzymes and multivitamin supplementation on body weight gain and hematological parameters (TEC, Hb content, PCV and ESR). A total of 200 day old broiler chicks were randomly selected and divided into four equal groups (50 x 4) as T 0 , T 1 , T 2 and T 3 . Group T0 was considered as control, (fed only with commercial ration) and other groups T 1 , T 2 and T 3 were treated at a dose rate of 0.5g multivitamins per liter of drinking water, 1g enzymes per liter of drinking water and 0.5g multivitamins plus 1 g enzymes per liter of drinking water, respectively, from 0 to 28 days of experiment. It was observed that enzymes and vitamins supplementation significantly (p<0.01) increased body weight with better physical appearance. TEC, PCV and Hb content increased significantly (p<0.01) in the treated groups as compar...

 

JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES Background Presently, the global demand for livestock product is growing. Also the demand of livestock product expected to double by 2050 due to the growing population and improved standard of living. Therefore, there is an urgent need to expand the livestock sector to meet the demand of growing population. Climate change is the current burning issue which is threatening the livestock sector. Livestock sector was adversely affected by the detrimental effects of persisting extreme weather conditions. The changes in the environmental factor such as temperature, rainfall, relative humidity, wind speed and solar radiation are directly and indirectly affecting the livestock productivity. Climatic extremes and the seasonal fluctuation affect the quantity and quality of fodder and water resources and also make them prone to new diseases. Among the climatic variables, heat stress seems to be the most in...
