Rabbit meat is popular in European and other countries. China is a major producer of rabbit meat; Laiwu black and Minxinan black rabbits are local black meat rabbit breeds used in China. In this study, Laiwu black rabbits, Minxinan black rabbits and Hyla commercial rabbits were selected for meat quality testing. The results illustrated that both Laiwu black and Minxinan black rabbits have certain advantages in terms of nutritional indicators while also having good meat colour and flavour.

Overall, supplementing quail diets with selenium-enriched yeast (SY) at 3.5 mg kg^-1 led to improved growth, health, and selenium content in eggs and meat, indicating its potential as a beneficial dietary additive.

This study assessed the effects of incorporating underutilized bitter vetch and sorghum grains on the performance of local goats. While growth parameters were unaffected, sorghum grains lowered carcass mesenteric fat and increased back lightness. Regarding meat quality, sorghum decreased ash, C18:2 n-6, and polyunsaturated fatty acids (PUFAs), while bitter vetch decreased protein but increased C18:3 n-3. Bitter vetch and sorghum grains can be incorporated into fattening diets for goat kids.

This study on Yanbian yellow cattle, known for their quality meat, examined fat from various body regions to understand differences in fat content and gene activity. We found 16 different fats in abdominal tissue, with unique fats in subcutaneous and other tissues. Kidney fat cells were larger than those in other areas. Gene activity varied significantly, with different genes being the most active in various tissues. 

DGAT1 influences milk yield and quality. Prior studies had limitations: small sample sizes, no environmental effects, and poor lactation records. Our study of 1104 Holstein Friesian and Jersey cows used polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) and Sanger sequencing for genotyping. We evaluate genotypic and allelic frequencies, population genetics, and phenotypic effects. Our findings offer more reliable interpretations at both phenotypic and genotypic levels.

The goal of the current study was to determine how dietary black pepper oil (BPO) supplementation affected growth performance, characteristics of growing quails' immunity, antioxidant status, and carcass yield. In conclusion, dietary BPO supplementation in Japanese quails' diet can boost growth performance and antioxidant indices, enhance lipid profile and carcass traits, and reduce intestinal infections.

The aim of the study was to use a digital system for the documentation of treatments and to investigate treatments, performance parameters and breeds. Farrowing-related treatments and high treatment indices of the sow related with an increase in stillborn piglets and high treatment indices of the sow resulted in fewer piglets born alive. Sows with parity of 1 had the highest treatment indices, which decreased over parities and increased for parity ≥8.

This paper highlighted the higher antioxidant potential of milk obtained from cows maintained in the traditional production system in the spring/summer season, primarily as a result of the increasing content of antioxidant, fat-soluble vitamins. 

This study was conceptualized as a prototype for other studies. Insights are provided into the effects of breed and sex on the slaughter characteristics, carcass traits, meat quality and fatty acid composition of young animals, which were formed based on the enteric emission (CH₄) levels and animal protein production potentials of different geographical regions. 

The aim of the research was to compare the thickness and the medullation of white and coloured wool from alpacas of different ages. The colour of the wool did not significantly affect the thickness and degree of medullation of the alpaca wool. Discontinuous medullas are found even in very fine hair. With age, the mean fibre diameter increased; the share of non-medullated fibres in the fleece decreased; and the share of medullated fibres, especially those with an discontinuous medulla, increased.

Peroxiredoxin-6 (PRDX6) is expressed in the epididymal tissue, epididymal fluid, and epididymal sperm of sheep. As the sperm mature and transit through the epididymis, the intracellular distribution of PRDX6 gradually becomes more extensive. This suggests that PRDX6 has an important role in promoting sperm maturation.
