Adrián Halvoník, Nina Moravčíková, Monika Chalupková, Radovan Kasarda

Czech J. Anim. Sci., 2024, 69(7):269-279 | DOI: 10.17221/91/2024-CJAS  

Abstract: Management of inbreeding is one of the crucial parts of breeding programs in livestock populations. Traditionally, the inbreeding coefficient is calculated using pedigree data; however, it can also be estimated from genomic data. Nowadays, various approaches to estimating genomic-based inbreeding coefficients are increasingly integrated into research and breeding practices. These genomic estimators can supplement or replace pedigree-based coefficients. Each genomic-based inbreeding coefficient has its own properties and different ranges of values, and some of them need specific settings for calculation. Moreover, depending on the methodological...

Czech J. Anim. Sci., 2024, 69(7):255-268 | DOI: 10.17221/36/2024-CJAS  

Sows are selected for their prolificacy. Therefore, assessing difficulties that can be associated with large litters is crucial. This review aims to highlight the factors that can affect reproductive performance such as breed, parity, litter size, environment, and nutrition. Understanding these factors can help producers make informed decisions about sow management and other aspects. Higher within-litter variation is the result of  a  high number of piglets born. It has been determined that large litter sizes pose a risk to animal welfare in the pig industry. Moreover, large litters bring more piglets with low birth weight leading to high pre-weaning...

Hew Wei Ee, Suriya Kumari Ramiah, Saminathan Mookiah, Zulkifli Idrus

Czech J. Anim. Sci., 2024, 69(4):119-128 | DOI: 10.17221/175/2023-CJAS  

Poultry are monogastric animals that share a fat tissue structure that is strikingly comparable to the fat in animal feed. This indicates that the kind and source of fat in animal diets can significantly impact the accumulation and composition of fatty tissue in the resulting carcass. Hence, feeding (or dietary) manipulation is one of the best and commonly employed management strategies to improve of gut health and function in broiler production. Medium-chain fatty acids (MCFAs) are fatty acids with six to twelve carbon atoms that are prevalent in coconut and palm kernel oils. Much research is being conducted on nutritional approaches to enhance gut...
