Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

Integrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Re‐thinking peripheral dysfunctions in obesity: The emerging role of sulphaceutics and sulphanutraceutics

British Journal of Pharmacology, EarlyView.
Obesity is a chronic, relapsing, multisystem disease in which cardiometabolic risk arises from excess adiposity and progressive dysfunction of peripheral organs, ultimately disrupting endocrine and metabolic crosstalk among tissues. Within this network, sulphur‐based biology, centred on hydrogen sulphide and related reactive sulphur species, has ...

THE SKY IS FALLING: AN EXAMINATION OF BROILER CONTRACT DESIGN AND GROWER REVENUES [PDF]

A math program is used to examine an integrators problem of assigning broiler growers into settlement pools. The integrator varies the size and frequency of flock placements by grower ability. This differentiates grower incentives by ability.

Genetic Evaluation of Pure Line Laying Hens Based on Crossover Testing Data From Simulated Populations

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Commercial laying hen breeding programs aim to maximize the performance of crossbred animals. However, selection is usually based on data from pure lines raised in controlled nucleus environments, which may not fully predict the yields under commercial conditions.

Unraveling Biotypes Related to Thermotolerance During Lactation in Maternal‐Line Pigs Through Principal Component and Factor Analyses

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Heat stress imposes significant challenges to welfare, health, and productivity of lactating sows due to their limited thermoregulatory capacity and increased metabolic heat load. Genetic selection for improved heat tolerance is a promising yet complex approach, given the large number of biological processes involved in heat stress response ...

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

Journal 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

A note on the effects of a combination of an enzyme complex and probiotic in the diet on performance of broiler chickens [PDF]

, 2011
peer-reviewedThe object of this experiment was to investigate the effect of an enzyme complex and a probiotic mixture, offered either singly or in combination, in the diet of broiler chickens (from 1 to 47 days of age) on growth and digestive tract ...

PRODUCTION AND PROFITABILITY RESPONSES TO ALTERNATIVE PROTEIN SOURCES AND LEVELS IN BROILER RATIONS [PDF]

Profitability of using alternative protein sources in broiler feed is investigated through the development of a two-stage mathematical program that optimizes broiler production. A case study of peanut meal vs. soybean meal is examined.

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

Journal 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
