Mixed management in growing and finishing pigs: Differences between gender and their impacts on behavior, growth performance, and physiological parameters
(Public Library of Science, 2023-04-13)
Mixing, a common management strategy used to regroup pigs, has been reported to impair individual performance and affect pig welfare because of the establishment of a new social hierarchy after regrouping. ...
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 ...
Parámetros genéticos de rasgos productivos de cuyes (Cavia porcellus) de las líneas Saños y Mantaro
(Universidad Nacional Mayor de San Marcos, 2022-06-29)
El objetivo del estudio fue estimar los componentes de varianzas, la heredabilidad y correlaciones genéticas y fenotípicas de los rasgos productivos de las líneas de cuyes Saños y Mantaro, desarrolladas ...
Integration of GWAS, pathway and network analyses reveals novel mechanistic insights into the synthesis of milk proteins in dairy cows
(Nature Research, 2018-01-12)
The quantities and proportions of protein fractions have notable effects on the nutritional and technological value of milk. Although much is known about the effects of genetic variants on milk proteins, ...
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 ...
An association analysis between a polymorphism in the SEC24A gene and lipid traits recorded in Duroc pigs
(Taylor & Francis Open Access, 2021-10-05)
By regulating the expression of low-density lipoprotein receptors (LDLR), the SEC24A protein modulates the clearance of plasma cholesterol in mice. The whole-genome sequencing of five Duroc boars that ...
