Immune Response and Fatty Acid Profile of Eggs from Laying Hens Fed Fermented Feed Rich in Polyunsaturated Fatty Acids

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

Sensory and fatty acid profile of eggs from commercial hens fed rendered spent hen meal.

The objective of the study was to determine sensory characteristics and fatty acid profile of eggs from commercial laying hens fed rendered spent hen meal (RSHM). Eggs were collected on a daily basis from Single Comb White Leghorn hens between 43 and 60 wk of age. The hens were fed a layer diet containing either 0, 2.5, 5.0, 7.5, or 10.0% RSHM from 48 to 60 wk in Trial 1, and from 43 to 55 wk i...

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...

Effects of Polyunsaturated Fatty Acids on Immune Response of Avian

Polyunsaturated fatty acids (PUFA) are important components of cell membrane phospholipids and play important roles in lipid metabolism, gene expression and cell membrane function. Changes in fatty acid composition of cell membrane phospholipids would have an impact on the immune function. In this paper, the effects on avian immune function and regulation mechanism of PUFA were summarized.

Immune response of cows fed polyunsaturated fatty acids under high ambient temperatures.

The aim of the experiment was to determine the effects of 2 different fat supplementations on immune functions of dairy cows under high ambient temperatures. The experiment involved 24 Italian Friesian cows, divided into 3 groups of 8 animals, that were subjected to fat supplementations based on whole flaxseed (FS) or microencapsulated fish oil (FO). At d 0, 45, and 90 of the experiment, lympho...
