Effects of maternal nutrition regimen of ewes on performance, carcass, and meat traits of their feedlot-finished lambs.

The objective of this study was to evaluate the effects of diets with two energy levels fed to Ile de France ewes during the last third of gestation on the performance, carcass, and meat traits of their offspring. Treatments were: D0: maternal diet meeting the requirements for the last third of gestation, and D20: maternal diet containing an additional 20% energy requirements. Twenty single-born male lambs, ten from each group of ewes, were weaned at 60 d (18.

Crude glycerin is an efficient alternative to corn in the diet of feedlot lambs.

The objective of this study was to evaluate the intake, digestibility, nitrogen balance, and performance of feedlot lambs fed diets containing crude glycerin. A total of 30 Ile de France lambs were confined to individual pens at an average age of 45  : 15.1  initial body weight and 32.

Feedlot of lambs fed biodiesel co-products: performance, commercial cuts and economic evaluation.

The aim of this study was to evaluate the animal performance, commercial cuts, and their yields within the production system, and economics of sheep production, of lambs finished in feedlots and fed with or without biodiesel co-products. A total of 40 lambs were divided into four biodiesel co-product treatment groups: a no-treatment control; peanut meal; crude glycerin; and peanut meal + crude glycerin. Animal performance did not differ (P > 0.
