Amino acid supplementation of a corn-soybean oil meal chick ration

Dietary Formulation with Poultry by-Product Meal on a Total Amino Acid vs. a Digestible Amino Acid Basis

Previous results indicated that performance of chicks fed a high level (10%) of poultry by-product meal(PBM) was lower than performance of chicks fed a corn-soybean meal (SBM) diet. The latter difference was hypothesized to be due to variation in digestible amino acid (AA) levels among the diets. This study evaluated diets containing PBM formulated on equivalent total AA basis vs. an equivalent...

Broiler Diets Formulated Based on Digestible Amino Acid Values as Determined by in vivo and Prediction Methods

The aim of the present study was to assess whether near infrared reflectance spectroscopy (NIRS) and regression equations are the practical and accurate approach of nutritional assessment of common feedstuffs. Therefore two experiments were conducted to study the effect of amino acid determination methods on broiler performance. In experiment I, two hundred thirty four male Ross broiler chicks ...

The effect of adding APF supplements and concentrates containing supplementary growth factors to a corn-soybean oil meal ration for weanling pigs.

A New Precision–Fed Chick Assay for Determining True Metabolizable Energy Values of some Poultry Feed Ingredients for Broiler Chickens

Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...

Effects of Bioassay and Age on Amino Acid Digestibility and Metabolizable Energy of Soybean, Sunflower and Canola Meals

These experiments were conducted to determine metabolizable energy and amino acid digestibilities of soybean meal, sunflower meal and canola meal in broiler chickens by using titanium oxide as indigestible marker in intact or caecectomized cockerels. Ileal and total tract digestibility of amino acids were measured using broiler chickens, moreover, digestibility were also determined in the intac...
