Genetic parameters and expected responses to selection for components of feed efficiency in a Duroc pig line
(BMC, 2017-12-01)
Background: Improving feed efciency (FE) is a key factor for any pig breeding company. Although this can be achieved by selection on an index of multi-trait best linear unbiased prediction of breeding ...
The effect of a high monounsaturated fat diet on body weight, backfat and loin muscle growth in high and medium-lean pig genotypes
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, 2012-01-23)
The objective of this study was to evaluate whether the use of a diet rich in oleic acid could have an effect on daily
weight gain, backfat and loin muscle (Longissimus thoracis) depth. One hundred and ...
Detection of homozygous genotypes for a putatively lethal recessive mutation in the porcine argininosuccinate synthase 1 (ASS1) gene
(Wiley, 2019-11-15)
The sequencing of the pig genome revealed the existence of homozygous individuals for a nonsense mutation in the argininosuccinate synthase 1 (ASS1) gene (rs81212146, c.944T>A, L315X). Paradoxically, ...
Genetic comparison of milk production and composition in three maternal rabbit lines
(Universidad Politécnica de Valencia, 2014-12-18)
The aim of this study was to compare 3 Spanish maternal rabbit lines (A, V and LP) in terms of milk production and composition. These lines were founded on different criteria but selected for litter ...
Influence of pre-storage incubation on hatchability traits, thyroid hormones, antioxidative status and immunity of newly hatched chicks at two chicken breeder flock ages
(Elsevier, 2017-04-17)
Egg storage longer than 7 days is associated with negative effects on hatchability traits. Pre-storage incubation has been a suggested method to reduce the negative effects of long-term storage times ...
In vivo safety evaluation of the Clostridium butyricum MIYAIRI 588 strain in broilers, piglets, and turkeys
(SAGE Publications, 2019-02-11)
Clostridium butyricum MIYAIRI 588 (CBM 588) is a nonpathogenic, anaerobic, gram-positive bacillus characterized by the production of short-chain fatty acids, including butyrate. The safety and tolerance ...
Indirect genetic effects on the relationships between production and feeding behaviour traits in growing Duroc pigs
(Cambridge University Press, 2019-10-01)
Performance and feeding behaviour traits in growing pigs could be affected by social interaction effects when animals are raised in group. So, properly knowing the genetic correlations between direct ...
Inbreeding depression load for litter size in Entrepelado and Retinto Iberian pig varieties
(Oxford University Press, 2019-03-14)
Individual-specific hidden inbreeding depression load (IDL) can be accounted for in livestock populations by appropriate best linear unbiased prediction approaches. This genetic effect has a recessive ...
Comparison of behaviour, performance and mortality in restricted and ad libitum-fed growing rabbits
(Elsevier, 2015-03-02)
The objective of this study was to determine whether rabbits fed in a restricted regimen (75%) showed increased competition for feeding, drinking and use of specific areas of the cages as compared with ...
Nutrient supply affects the mRNA expression profile of the porcine skeletal muscle
(BMC, 2017-08-10)
Background: The genetic basis of muscle fat deposition in pigs is not well known. So far, we have only identified a limited number of genes involved in the absorption, transport, storage and catabolism ...
