Short-term effects of lower oil dried distillers grains with solubles in laying hen rations.
Extraction of oil from dried distillers grains has become a common practice among US ethanol producers. The valuable oil has been diverted to markets other than poultry feed, leaving new dried distillers grains with solubles (DDGS) products higher in fiber and purportedly lower in ME. This study compared 3 DDGS products with 10.3, 7.3, or 5.2% ether extract, respectively, with a corn-soy contro...
متن کاملDried Distillers Grain with Solubles in Laying Hen and Pullet Rations
A study was conducted to test the inclusion rates of corn dried distillers grains with solubles (DDGS) in laying hen diets on egg production (EP) parameters for a full production cycle. Two hundred eighty-eight Bovan Single Comb White Leghorn laying hens were fed diets containing 0, 5, 10, 15, 20, or 25% DDGS from 24 to 46 wk and 47 to 76 wk of age for Phase I and Phase II, respectively. The di...
متن کاملThe response of liver enzymes to feed restriction and subsequent ad lib. feeding in the laying hen.
1. The effects of restricted feeding, and ad lib. feeding following food restriction, on hepatic carbohydrate and lipid metabolism in the laying hen were studied. 2. The birds were allocated to four groups and given either 92, 84 or 75 g/d or allowed ad lib. access to food. 3. Food restriction significantly reduced liver total lipid content compared with ad lib.-fed control birds and this was r...
متن کاملEffect of a phytogenic feed additive on performance, ovarian morphology, serum lipid parameters and egg sensory quality in laying hen
This present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg-1 phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. The results of experiment have shown that egg weight was increased by supplementation of 12 g kg-1 feed additive wherea...
