Welfare of broiler chickens [PDF]
Italian Journal of Animal Science, 2009 Broiler chickens have been selected for their rapid growth rate as well as for high carcass yields, with particular regard to the breast, and reared in intensive systems at high stocking density ranging from 30 to 40 kg live weight/m2. These conditions lead to a worsening of the welfare status of birds. In Europe a specific directive for the protection

Enzymatic programs for broilers [PDF]
Brazilian Archives of Biology and Technology, 2009 Two trials were conducted on floor pens to evaluate the performance of broilers fed with diets contained different carbohydrases enzyme programs at different ages. Trial 1- The body weight gain (BWG) was affected by the Negative Control (NC) treatment (P<0.05). However, when the birds were fed with the NC diet + Amilase (AMY)+Xilanase (XYL), the BWG
