Supplemental Methionine in a Sixteen Percent Protein Diet for Laying Chickens

The Sixteen-percent Solution: Critical Volume Fraction for Percolation

Effects of dietary protein levels and supplemental lysinge on performance of laying hens

Bioavailability comparison between herbal methionine and DL-methionine on growth performance and immunocompetence basis in broiler chickens

BACKGROUND:Herbal methionine can be compared relative toDl-methionine with evaluation of bioavailability of this source ofmethionine. OBJECTIVES: An experiment was carried out todetermine the relative bioefficacy of herbal methionine (H-Met)®relative to DL-methionine (DL-Met) on performance criteria andimmunocompetence of Met sources in male broilers. Atotal of 160male broilers were fed a Met-d...

Laying hen productivity as affected by energy, supplemental fat, and linoleic acid concentration of the diet.

A trial using 720 Isabrown hens was conducted to determine the influence of energy (AMEn), supplemental fat (SFAT), and linolenic acid (LIN) concentration of the diet on performance and weight of eggs and egg components throughout the laying cycle (22 to 65 wk of age). There were six treatments whose calculated AMEn, SFAT, and LIN content were, respectively: 1) 2,810 kcal/kg, 0%, 1.15%; 2) 2,81...

Supplemental L-arginine Modulates Developmental Pulmonary Hypertension in Broiler Chickens Fed Reduced-Protein Diets and Reared at High Altitude

This experiment was conducted to evaluate the effects of supplemental L-arginine (ARG) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. A total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. Treatment groups were designed as a normal-prote...
