In total, 240 pigs were used to compare growth performance and carcass quality traits of immunocastrated males (ICM), surgically castrated males (SCM), and intact females (IF) of crossbreds from Large White × Landrace females and Duroc (DU) or Pietrain (PI) sires destined to the dry-cured industry. Between the 2 Improvac injections (87 and 137 d of age), ICM and IF had less ADG than SCM (P < 0....

The objective of this study was to evaluate the impact of diets enriched with plant oils or seeds, high in polyunsaturated fatty acids (PUFA), on the fatty acid profile of sheep intramuscular and subcutaneous adipose tissue (SAT). Sixty-six lambs were blocked according to initial body weight and randomly assigned to six concentrate-based rations containing 60 g fat/kg dry matter from different ...

Aim of the study: To evaluate consequences for pork quality traits replacing soybean meal with Narbon vetch in pig diets.Area Castilla-Leon, Spain.Material and methods: 48 Duroc × Iberian barrows were fed diets 0% (V0), 5% (V5), 10% (V10) 20% (V20) inclusion vetch. Pork investigated 1) intramuscular fat, protein moisture content fresh loin, 2) fatty acid composition subcutaneous 3) sensory attr...

Intramuscular fat (IMF) content is a crucial parameter for estimating meat quality. Growing evidence indicates that gene regulation plays an important role in IMF deposition. This study aimed to determine the function of Mfsd2a chicken intramuscular preadipocytes. In present study, high mRNA levels were observed liver and adipose tissues broilers. Subsequently, we synthesized small interfering ...

Intramuscular fat (IMF) content and composition are considered crucial indicators of porcine meat quality. However, the molecular mechanism of porcine IMF development is still mostly unclear. Recently, new evidence suggested that microRNA (miRNAs) play important roles in porcine intramuscular adipogenesis. Previously, microRNA-125a-5p (miR-125a-5p) was identified as an important regulator of ad...

We attempted to determine whether shortage of dietary threonine enhances the accumulation of intramuscular fat (IMF) in porcine muscle. Although dietary low levels of lysine enhanced the concentration of IMF in the longissimus dorsi and rhomboideus muscles, dietary low threonine did not. We conclude that the effect of dietary threonine levels on the accumulation of IMF in porcine muscle is negl...

Animals accumulate fat in tissues as subcutaneous, intermuscular, intramuscular, and abdominal fat. Genetic interrelationships of respective fat depositions, however, have not been examined in depth. This study estimated genetic parameters for subcutaneous, intermuscular, and abdominal fat areas of 545 Duroc purebred pigs slaughtered at 105 kg of BW. Measurements were obtained using an image an...

Context Climate and economic changes promote the encroachment of woody plants on marginal mountain pastures. In Alps, main invader is nitrogen-fixing shrub Alnus viridis (green alder). Robust breeds different ruminant species may perform well these shrub-encroached pastures.Aims To assess effects A. levels pastures growth performance carcass meat characteristics cattle sheep.Methods For 8–9week...

Improving the traits that underlie meat quality is a major challenge in the beef industry. The objective of this paper was to detect QTL linked to sensory meat quality traits in 3 French beef cattle breeds. We genotyped 1,059, 1,219, and 947 young bulls and their sires belonging to the Charolais, Limousin, and Blonde d'Aquitaine breeds, respectively, using the Illumina BovineSNP50 BeadChip (Ill...
