Modeling energy utilization in broiler breeders, laying hens and broilers [PDF]

Revista Brasileira de Ciência Avícola, 2004
The factorial approach has been used to partition the energy requirements into maintenance, growth, and production. The coefficients determined for these purposes can be used to elaborate energy requirement models. These models consider the body weight, weight gain, egg production, and environmental temperature to determine the energy requirements for ...

Vitamin D3 Is Not a Limiting Nutrient Regarding Growth Performance and Tibia Parameters in the Rearing Period of Laying Hens Bred for High Laying Performance Compared to Non‐Selected Resource Populations

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Bone damages in laying hens are of great concern in poultry farming. Besides various risk factors like housing systems or nutrient supply during egg production, it has often been hypothesized that genetically high‐performing laying hens may be more prone to bone damages. The relevance of dietary support during the rearing period of pullets for

Response of Broilers to Moenomycin

Poultry Science, 1970
Abstract DURING screening for new antibiotics, Lindner and Wallhausser (1955) isolated a previously undescribed antibiotic from an antibiotic-producing streptomyces strain. This compound was designated moenomycin. The fermentation and isolation of this antibiotic are described by Wallhausser et al. (1965).

Spread of avian pathogenic Escherichia coli ST117 O78:H4 in Nordic broiler production

BMC Genomics, 2017
BackgroundEscherichia coli infections known as colibacillosis constitute a considerable challenge to poultry farmers worldwide, in terms of decreased animal welfare and production economy. Colibacillosis is caused by avian pathogenic E. coli (APEC). APEC

Validation and Evaluation of Lateral Flow Tests for the Detection of Antimicrobial Residues on Poultry Feathers

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Persistence of antimicrobial drugs (AMDs) administered to poultry is longer in feathers than in edible tissues. Hence, poultry feathers are a suitable matrix to investigate historical exposure contributing to antimicrobial resistance, since current detection methods are either non‐specific or highly technical and costly.

Selection for Tameness in Red Junglefowl Recapitulates Genetic Loci Associated With Domestication‐Related Brain Composition

Molecular Ecology, EarlyView.
ABSTRACT Domestication involves huge phenotypic shifts via strong directional selection. The resulting changes, often termed the Domestication Syndrome, typically encompass numerous traits; however, the most universal of these are changes in reduced fear of humans (tameness) and brain composition.

Evaluation of blood erythroid parameters in male broiler chickens (Ross 308) with the Sysmex XT‐2000iV and Sysmex XN‐1000V analyzers and determination of hematological reference intervals obtained with manual and instrumental methods

Veterinary Clinical Pathology, EarlyView.
Abstract Background The presence of both nucleated RBC and thrombocytes in birds makes the determination of hematological variables difficult. This leads to time‐consuming manual evaluation. New‐generation analyzers are hypothesized to be both time‐saving and accurate. Objectives The objective was to evaluate the performance of two hematology analyzers
