Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

Animal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

Animal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

Longitudinal study on background lesions in broiler breeder flocks and their progeny, and genomic characterisation of Escherichia coli

Veterinary Research, 2022
In broiler breeders, background mortality is rarely addressed, however, it represents the death of a vast number of birds, a constant productivity loss, welfare concerns and it might affect chick quality.

Studies on the Biotin Requirement of Broiler Breeders ,

Poultry Science, 1972
Abstract The minimum requirement of biotin for maximum hatchability of eggs and livability of chicks was determined for broiler breeder hens maintained in individual cages. Groups of hens were fed casein-gelatin, glucose diets containing 20, 40, 60, 100, 180 and 340 μg. biotin/kg. of diet. The requirement was found to be approximately 100 μg.

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

Animal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

What affects nesting behaviour in broiler breeders? : The role of motivation, physical ability and social opportunity

, 2021
Broiler breeders have a different genetic background from laying hens, since they have been selected for fast growth of their offspring. Selection for fast growth negatively affects the reproductive system, but the behaviour of broiler breeders also ...

Body Composition of the Broiler-Breeder Pullet

Poultry Science, 1990
Broiler breeder pullets were reared on a standard breeder-grower diet in accordance with breeder recommendations to 10 wk of age, with samples of the birds being selected for carcass analysis at 2, 3, 4, 5, 6, 7, 8 and 10 wk of age. At 10 wk of age, 264 pullets were assigned to one of three diets formulated to contain 15% CP and to provide 2,550, 2,800
