Performance Characteristics and Nutritional Comparison of Broiler Chickens Fed with Barley and Triticale Based Diets
This study was performed with growing chicken (14 to 56 d of age) to evaluate the effects of feeding them a barley or triticale-based diet. The treatments were corn diet (1) as a control, hulless barley diet with (5) or without (2) enzyme, triticale diet with (6) or without (3) enzyme and hulled barley diet with (7) or without (4) a commercial β-glucanase enzyme. In a digestibility trial, 21 ma...

متن کاملThe zinc requirements of broiler chicks and turkey poults fed on purified diets.
Chicks and turkey poults were fed for 3 weeks on low-zinc diets, prepared from purified ingredients, supplemented with zinc oxide at graded levels. Birds of both species given the unsupplemented basal diets grew poorly, with high mortality rates. All had severe hyperkeratosis but bone development was normal. Only when birds received diets with low concentrations of added Zn were leg abnormaliti...
متن کاملEffect of Supplemental Enzyme on Nutrient Digestibility and Performance of Broiler Chicks Fed on Diets Containing Triticale
The influence of enzyme supplementation on performance and digestibility of dry matter and protein in young broiler chicks was examined for a diet based on triticale supplemented with different levels of enzyme. In a completely randomized design, two hundred d-old chicks (Ross strain) were divided into 20 groups, ten chicks per group. A basal diet containing 65% triticale was supplemented with ...
