Performance of homozygosity by descent in two mice lines divergently selected for birth weight environmental variability

Scientific Reports
Inbreeding can have negative effects, such as increasing the expression of deleterious alleles or reducing fitness. A method based on Hidden Markov Models (HMM) was developed to determine the probability of an individual genome in a homozygous-by-descent

A meta-analysis approach for annotation and identification of lncRNAs controlling perirenal fat deposition in suckling lambs

Animal Biotechnology
Long non-coding RNAs (lncRNAs) are being studied in farm animals due to their association with traits of economic interest, such as fat deposition. Based on the analysis of perirenal fat transcriptomes, this research explored the relevance of these ...

Determination of α-tocopherol in pork with high intramuscular fat content

Grasas y Aceites, 1996
Extraction of α-tocopherol from pork samples with low (3%) (LF) or high (9%) (HF) amount of intramuscular fat have been carried out by three different methods, two of them based in saponification plus extraction of α-tocopherol and the other one without ...

Bases para un desarrollo ganadero sostenible: la consideración de la producción animal desde una perspectiva sistémica y el estudio de la diversidad de las explotaciones [PDF]

, 2003
La consideración de los sistemas de producción animal desde una perspectiva económica y mecanicista ha provocado en muchas ocasiones una falta de coordinación entre los agentes implicados en su mejora y las explotaciones y ha conducido al desarrollo de

Local climate and genetic influence on intraspecific variation in torpor physiology of a cave‐roosting bat

Functional Ecology, Volume 40, Issue 4, Page 857-867, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many small endotherms employ torpor as a survival strategy to reduce energy expenditure during periods with low food availability and cold temperatures. The expression and physiology of torpor can vary substantially within species because of phenotypic plasticity and ...

Integration of selective sweeps across the sheep genome: understanding the relationship between production and adaptation traits

Genetics Selection Evolution
Background Livestock populations are under constant selective pressure for higher productivity levels for different selective purposes. This pressure results in the selection of animals with unique adaptive and production traits.

Effect of gender, housing density and the interaction on growth performance and carcass and meat quality of pigs slaughtered at 110 kg body weight

Spanish Journal of Agricultural Research, 2012
A total of 228 crossbred pigs were used to investigate the effect of gender (gilts and barrows), density at housing (0.84 and 0.76 m2/pig) and the interaction on growth performance and carcass and merit from 19.4 to 110 kg body weight.
