Spectral Transforms as a Tool to Optimize Digital Phenotyping in Biological Images

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Modern livestock breeding has mastered genotyping. Genome‐wide association studies, genomic selection, and SNP arrays enable genetic merit prediction at lower cost. However, phenotyping remains the bottleneck, as manual measurement is slow, expensive, subjective, and unable to capture spatial or temporal trait organization. Digital phenotyping

Feeding Laboratory Mice: Comparing a Standard Versus a Purified Diet – Marked Effects on Digestive Physiology

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Diet composition and processing have a major impact on its utilisation by the animal, as is known from farm and pet animal species. This includes effects on energy and nutrient digestibility, the intermediary metabolism, and the intestinal microbiome, with all the resulting impacts. For laboratory animals, data is scarce on influencing factors

Body Composition of the Broiler-Breeder Pullet

open access: yesPoultry 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

Guanidinoacetic Acid Improves Growth Performance and Gut Health of Broilers Fed Metabolizable Energy‐Reduced Diets

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study was conducted to evaluate the effects of guanidinoacetic acid (GAA) supplementation to diets with different energy levels on growth performance, carcass traits, and gut health status in broiler chickens. A total of 9500 1‐day‐old Ross 308 broilers (equal numbers of males and females) were allocated to 1 of 5 dietary treatments (10 ...

Copper requirements of broiler breeder hens

open access: yesPoultry Science, 2018
One-hundred-twenty Cobb 500 hens, 20 wk of age, were randomly allocated into individual cages with the objective of estimating Cu requirements. After being fed a Cu deficient diet for 4 wk, hens were fed diets with graded increments of supplemental Cu (0.0; 3.5; 7.0; 10.5; 14; and 17.5 ppm) from Cu sulfate (CuSO4 5H2O), totaling 2.67; 5.82; 9.38; 12.92;

Global Poultry Feed Protein Sources: Trends, Challenges, and Sustainability Perspectives Using FAOSTAT Data

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT The global poultry industry is one of the fastest‐growing livestock sectors, with worldwide chicken stocks exceeding 32 billion heads and meat production surpassing 144 million tonnes in 2024 (FAOSTAT, 2026). Conventional protein sources, particularly soybean meal (SBM) and fishmeal, underpin most commercial poultry diets but face mounting ...

Combination of In Ovo Nutritional Components Improves Embryonic Development, Growth Performance, and Gut Health in Broiler Chickens

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the effects of intra‐amniotic administration of combined energy, amino acid, and vitamin sources on embryonic development, post‐hatch growth performance, and intestinal health in broiler chickens. On Day 18 of incubation, 460 fertile Ross 308 eggs were allocated to four groups: non‐injected negative control (NC), saline ...
