AIM To study the impact of deficiency of second line limiting amino acids (SLAA; valine, isoleucine and tryptophan) on the production performance and carcass characteristics of commercial broilers. MATERIALS AND METHODS A control (T1) corn-soy diet was formulated to contain all essential AA on standardized ileal digestible basis; While in T2-a 'moderate SLAA deficit' diet was formulated by re...

to determine the effect of graded levels of low glucosinolate CM, up to complete replacement of soybean meal, on the performance of laying hens. Wheat-based diets were formulated on a digestible amino acid basis with 4 levels of CM (0 to 16.7%) and fed to 3 commercial laying hen strains, Lohmann Brown (LOH), ISA Brown (ISA), and Lohmann LSL (LSL). Rations were fed from 19 to 59 wks of age, with...

A total of 156 finishing pigs (72 barrows and 84 gilts, initially 110 lb) were used to determine the effects on growth performance of increasing meat and bone meal. Pigs were housed in an environmentally regulated finishing building, with two pigs per pen. There were six pens of barrows and seven pens of gilts per treatment. Pigs were blocked by initial weight and sex, and then allotted to one ...
