The Chloride Requirement of the Broiler Breeder Hen

Poultry Science, 1984
An experiment was conducted to determine the chloride requirement of broiler breeder hens fed a corn soybean meal diet. Levels of .135 and .09% (daily intake of 208 and 139 mg) supplemental chloride were required for maximum egg production and egg weight, respectively. However, a supplemental level of .135% was required to maximize hatchability.

Magnolol Improves Intestinal Antioxidant Capacity and Barrier Function by Activating the Nrf2 Signaling Pathway in a Piglet Model

Food Frontiers, Volume 7, Issue 3, May 2026.
ABSTRACT Magnolol is a natural bioactive phenolic compound with potent antioxidant properties and plays an important role in modulating intestinal healthy. However, the underlying mechanisms of magnolol in alleviating intestinal oxidative stress damage and improving the intestinal barrier integrity remain unknown. Thus, this study aimed to evaluate the

Application of Artificial Neural Network and the Monomolecular Model in Describing the Relationship Between Body Weight Gain and Metabolizable Energy Intake in Egg‐Type Pullets

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Energy utilization in egg‐type pullets is shaped by genetic diversity and body‐weight dynamics. A simple mechanistic model captured interpretable energy–growth relationships, while artificial neural networks improved predictive accuracy, highlighting complementary modelling approaches for understanding and predicting pullet energy dynamics.

Applied Research Note: Maternal flaxseed diet did not affect body weight of broiler chickens diagnosed with novel avian reovirus and infectious bronchitis

Journal of Applied Poultry Research
SUMMARY: Feeding breeder hens diets enriched with omega-3 fatty acids (n-3 FA) has previously been shown to increase their progeny's immunocompetence. During an experiment to assess the effects of maternal-fed n-3 FA on broiler behavior, broiler chickens

Abdominal Fat in Broiler Breeders

Poultry Science, 1984
Abstract Forty sires and forty dams from a female selection and a control broiler line were slaughtered at 47 weeks of age. Males had a mean of .17% abdominal fat and females 3.32% with 37.5% of the males having little or no fat.

The Effects of Supplementation of Chlorella vulgaris Biomass on Egg Production and Composition of Laying Hens

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Dietary supplementation with Chlorella vulgaris up to 0.5% improved laying hen productivity, increasing egg number and daily production rate without compromising egg weight. Egg nutritional composition remained largely unchanged, with only indicative trends in fatty acid ratio and cholesterol, suggesting potential for productivity enhancement without ...
