Effects of medium-chain fatty acids on growth performance, microbial attributes, and fat deposition in broiler chickenReview

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...

Effects of age and litter-of-origin on cryopreserved spermatozoa in Sumava ramsOriginal Paper

Anežka Málková, Martin Ptáček, Filipp Georgijevič Savvulidi, Szabolcs Tamás Nagy, Luděk Stádník

Czech J. Anim. Sci., 2024, 69(4):129-138 | DOI: 10.17221/32/2024-CJAS

This study aimed to evaluate the influence of the internal factors of ram age and litter-of-origin on semen quality during the cryopreservation process in Sumava sheep rams. This breed is included in the protected genetic resources of the Czech Republic. The sires were systematically divided into four groups according to age (under 1.5 years, 1.5 to 2.5 years, 2.5 to 3.5 years, and over 4.5 years) and according to litter frequency (singletons vs twins). Semen was evaluated after equilibration, and after cryopreservation using iSperm^® mCASA and flow cytometry. During cryopreservation, there was a significant decrease in total sperm motility...

This study aimed to evaluate the effects of dietary levels of soluble and insoluble fibre on the performance and digestive development of slow-growing broilers during the starter period. A total of 400 one-day-old Isa Label^TM male chicks were used that were distributed in a completely randomized factorial design 2 × 2 + 1 (inclusion of 2% or 4% of corncobs as a source of insoluble fibre IF and citrus pulp as a source of soluble fibre (SF); and a control treatment) with eight replicates of 10 birds each. The addition of IF to diets improved the weight gain and feed conversion of broilers at 7 and 21 days of age. Both fibre sources added to diets...

Field study: Factors influencing virgin queen bee acceptance rate in Apis mellifera coloniesOriginal Paper

Agnese Smilga-Spalvina, Kriss Spalvins, Ivars Veidenbergs

Czech J. Anim. Sci., 2024, 69(4):155-164 | DOI: 10.17221/22/2024-CJAS

Regular replacement of old and problematic queen bees is necessary to maintain the strength and productivity of bee colonies. Beekeepers replace queen bees using queen cells, virgin queens, or mated laying queens. In this study, we explored factors influencing the acceptance of the virgin queens. A comprehensive field study was conducted in the summer of 2023, involving the introduction of 754 virgin queens of different age and 194 queen cells into mating nuclei of various states using three different methods. The article aims to provide recommendations to beekeepers for introducing virgin queens, thereby increasing the frequency of successful requeening....
