Nutritional Feasibility of L-Valine Inclusion in Commercial Broiler Diets
Introduction The poultry industry has recently dealt with fluctuating spikes in the price of various feed ingredients. When the cost of protein-rich feed ingredients goes up, the reduction of dietary crude protein via the use of commercially available amino acids becomes an effective formulation strategy that can reduce diet costs, maintain broiler performance and not interfere with feed millin...
متن کاملNutritional value of amaranth (genus Amaranthus L.) grain in diets for broiler chickens
The following characteristics were determined in raw and popped amaranth grain: crude protein (158.1 and 168.5 g/kg), ether extract (71.5 and 69.4 g/kg), neutral detergent fibre (NDF) (99.2 and 111.8 g/kg), cellulose (86.6 and 60.0 g/kg) and essential amino acids (Cys 4.2 and 4.1, Thr 6.0 and 6.5, Ala 8.8 and 9.2, Val 6.8 and 7.4, Ile 5.2 and 5.6, Lys 9.2 and 8.8, Arg 12.8 and 14.2 g/kg). In vi...
متن کاملValine and Isoleucine: The next limiting amino acids in broiler diets
Drastic genetic changes have occurred in many commercial broiler lines during the last years with regard to performance. This genetic improvement needs a corresponding adjustment of our knowledge about amino acid nutrition in broilers. Additionally, today broiler feed formulators are not only focused on minimising the costs. They also have to take into consideration environmental issues and the...
متن کاملPerformance 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 کاملEffect of the Phytase Inclusion in Broiler Breeder Diets on Fecal and Egg Characteristics
Objective: A study was conducted to determine the effect of phytase inclusion in broiler breeder diets on fecal and egg characteristics of individually caged females. Materials and Methods: A total of 184 female broiler breeders were fed growing and laying diets containing 0.7% or 2.7% calcium (Ca) and 0.35% or 0.12% available phosphorus (AvP), respectively, with one of four graded levels of ph...
