Therapeutic effect of flax-based diets on fatty liver in aged laying hens

The Possibility of Using Watermelon Waste in Laying Hens Diets

In this experiment 240 Hy-Line (W-36) laying hens from 65 to 75 weeks distributed in 5 treatments and 4 replicates (12 birds per replicate) in a completely randomized design were used. The amounts of watermelon skin meal (WSM) used to set the treatments were 0, 0.5, 1, 1.5 and 2% in 1 to 5 experimental groups. The results showed that using WSM up to 2% significantly improved the performance and...

Type of Fatty Acids, Lipoprotein Secretion from Liver and Fatty Liver Syndrome in Laying Hens

Unlike other vertebrates, liver is the main site of lipid biosynthesis and is particularly very active in egg laying adult females. Yolk lipids and proteins are secreted as lipoproteins under the influence of estrogen in the liver. When hepatic lipogenesis exceeds the capacity of fat transport as lipoproteins, triacylglycerols commence to accumulate in the liver, leading to fatty liver syndrome...

Behavior of laying hens on alfalfa crumble molt diets.

Several dietary alternatives to feed withdrawal have been proposed to induce a molt in laying hens. This study compared the behavior of laying hens on an alfalfa crumble diet (ALC) to hens that were either on a conventional layer diet (FF) or hens that had feed withdrawn (FW) during a 9-d trial. Each treatment consisted of 24 hens (3 hens per battery cage), and treatment began after a 2-week ac...

Response of laying hens to supplementation with various fatty acids when fed diets inadequate in protein and sulphur amino acids

Effect of Methionine and Energy Level in High Protein Organic Diets Fed to Laying Hens*

The objective of a 2 × 2 factorial study with laying hens was to evaluate the effect of dietary energy and DL-methionine (Met) supplementation in a high protein but sulphur amino acid deficient organic diet for laying hens on egg production, egg quality, and N retention and N excretion in manure. The model trial was conducted with 72 Bovans Brown hens from 24 to 53 weeks of age, allocated to 4 ...
