Study of meat quality and some genes expression associated with growth in three strains of Ross, Arian, and Cobb based on a basal diet [PDF]

مجله بیوتکنولوژی کشاورزی, 2022
ObjectiveOne of the goals of the poultry industry is to select animals that increased growth rates and also muscle mass while maintaining meat quality. The present study was conducted to evaluate performance, some meat quality characteristics, and gene ...

Comparative Investigation of Ross and Cobb Broiler Genotypes with Different Gender in terms of Slaughter, Carcass Characteristics and Some Meat Quality Traits

ISPEC Journal of Agricultural Sciences, 2023
The aim of this study was to compare the Ross and Cobb genotypes with different gender, which were widely used for poultry production in the world and in Turkey, in terms of slaughter, carcass and some meat quality characteristics. Carcasses used in the

Selective genotyping strategies for a sib test scheme of a broiler breeder program

Genetics Selection Evolution, 2023
Background In broiler breeding, genotype-by-environment interaction is known to result in a genetic correlation between body weight measured in bio-secure and commercial environments that is substantially less than 1. Thus, measuring body weights on sibs

Estimation of dam line composition of 3-way crossbred animals using genomic information

Genetics Selection Evolution, 2022
Background In genomic prediction including data of 3- or 4-way crossbred animals, line composition is usually fitted as a regression on expected line proportions, which are 0.5, 0.25 and 0.25, respectively, for 3-way crossbred animals.

Large- and medium-bodied terrestrial mammals of the Upper Berbice region of Guyana [PDF]

Check List, 2020
Large mammals are key contributors to forest ecosystems globally, but Neotropical mammal populations are understudied. We employed remotely triggered camera traps and track surveys to assess the mammal community in the newly accessible upper Berbice ...

Would large dataset sample size unveil the potential of deep neural networks for improved genome-enabled prediction of complex traits? The case for body weight in broilers

BMC Genomics, 2020
Background Deep neural networks (DNN) are a particular case of artificial neural networks (ANN) composed by multiple hidden layers, and have recently gained attention in genome-enabled prediction of complex traits.

Impact of feeding varying grower digestible lysine and energy levels to female Cobb MV × Cobb 500 broilers from 14 to 28 D on 42 D growth performance, processing, and economic return

Journal of Applied Poultry Research, 2020
Summary: Previous research in our laboratory has revealed that feeding crumbled diets with various levels of starter digestible Lys (dLys) and AME affects early feed conversion ratio (FCR) of Cobb MV × Cobb 500 broilers.

Morphological pattern of the livers of different lines of broiler chickens during rearing

Veterinární Medicína, 2013
The aim of this study was to analyse the microscopic and ultrastructural lesions of the livers of broiler chickens during fattening. Three genetic lines of broiler chickens (Ross 308, Cobb 500, Hubbard F15) were investigated. The liver samples were taken

Effect of genomic selection and genotyping strategy on estimation of variance components in animal models using different relationship matrices

Genetics Selection Evolution, 2020
Background The traditional way to estimate variance components (VC) is based on the animal model using a pedigree-based relationship matrix (A) (A-AM).

Validation with single-step SNPBLUP shows that evaluations can continue using a single mean of genotyped individuals, even with multiple breeds

Genetics Selection Evolution, 2023
Background In genomic prediction, it is common to centre the genotypes of single nucleotide polymorphisms based on the allele frequencies in the current population, rather than those in the base generation.
