Chicken meat is an important source of high-quality animal protein. Its consumption continues to grow in both developed and developing countries. Muscle fiber characteristics are key determinants quality quantity. Skeletal muscle a highly plastic tissue that affected by breed differences muscular tissues. However, studies regarding the effects different breeds tissues on fibers traits broilers lacking. In this study, Ross 308 chickens (fast-growing [FG] broilers) Xueshan (slow-growing [SG]...

This study evaluated the effects of muscle fiber characteristics on meat quality traits in 45 female fast- and slow-growing ducks. Three duck breeds at typical market ages were selected slaughtered, including fast-growing ducks (Cherry Valley duck) (Small-sized Beijing Liancheng White duck). M. pectoralis major (PM), m. soleus (SOL), gastrocnemius (GAS) extensor digitorum longus (EDL) used to assess as well properties. The results showed that compositions PM, GAS, EDL muscles only consisted...

The correlated response in traits encompassing meat quality, carcass, sexual maturity, egg production, and quality arising from selection for increased intramuscular fat (IMF) content of breast muscle were investigated the fifth generation a experiment including line (F) selected IMF randombred control (C). results showed that F (4.25%) was significantly higher (P < 0.001) than C (3.80%) after 5 generations selection. same trend observed thigh (20.03 vs. 19.41%, P 0.05). shear force lower...

Ammonia (NH3) is a harmful gas with irritating odor, and higher NH3 concentration was found in intensive poultry houses. Although the toxicity of well known, little attention has been given to mechanism poisoning chicken immune organs. To investigate NH3-caused inflammatory damage broiler spleens, this study, model for established, 3 levels (including microRNA [miRNA], mRNA, protein) were performed using qRT-PCR western blot. The results indicated that exposure caused microstructure...

The experiment began day 107 gestation continued until...

We analyzed the effects of polymorphisms follicle-stimulating hormone receptor (FSHR) gene on egg production in a Beijing You chicken population divergently selected for number, weight, and BW across 3 generations. The FSHR encodes hormone, which controls follicular development recruitment ovary. Seven SNP were investigated 768 pedigreed hens from G2 generation. Association analysis revealed that g.-310A > G, g.-181A T, g.159C T associated with number at different weeks age (P < 0.05)...

Olives are a rich source of compounds with antioxidant and anti-inflammatory activities. This study was designed to investigate whether standardized olive cake extract able alleviate oxidative stress, inflammation intestinal villus damage in model lipopolysaccharide (LPS)-challenged piglets. Thirty weaned piglets (6.9 ± 0.9 kg) were assigned five groups using randomized complete block design. Piglets fed basal diet before intraperitoneal (i.p.) injection physiological saline (C); alone (CL)...

The role of insect UDP-glycosyltransferases (UGTs) in the detoxification insecticides has rarely been reported. A UGT gene

Tributyrin and essential oils have been used as alternatives to antimicrobials improve gut health growth performance in piglets. This study was evaluate the effects of a dietary supplement with two encapsulated products containing different combinations tributyrin oregano or methyl salicylate on performance, serum biochemical parameters related physiological status, intestinal microbiota metabolites A total 108 weaned crossbred piglets (Yorkshire × Landrace, 21 ± 1 d, 8.21 0.04 kg) were...

Cherry Valley ducks (CVDs) and White Kaiya (WKDs) are judged to be fast- slow-growing lines, respectively. To investigate the carcass traits nutritional profile at their marketable ages, 12 birds (38 days for CVDs, n = 6; 56 WKDs, 6) were randomly selected slaughtered. Indicators such as breast muscle weight, shear force, proximate composition comprehensively detected. Although weight in WKDs significantly lower, remarkably higher intramuscular fat tenderness less moisture content observed...

This study was conducted to evaluate the effects of vitamin K (VK) supplementation on reproductive performance and bone metabolism-related biochemical markers in sows.Twenty-four Large White×Landrace sows (mean parity 4.04) were randomly assigned two dietary treatments (NC diet, a basal diet with 0.5 mg/kg VK3; VK 5 VK3) twelve replicates per treatment one sow replicate according parity. The experiment started day 107 gestation lasted until 21 lactation (weaning).We observed that there no...

The development of the knob in Chinese geese (Anser cygnodies) is an outcome extensive and prolonged selection breeding. serves not only as a visual indicator sexual maturity but also holds significance crucial packaging trait that attracts attention consumers attentions, who tend to distinctly prefer with larger knobs. Consequently, investigating formation practical value, it will help achieving external traits aligned consumers' preferences. To understand relationship between size,...
