Impact of microclimatic conditions on sperm production in Czech Holstein bulls: A correlational studyOriginal Paper

Czech J. Anim. Sci., 2025, 70(4):121-129 | DOI: 10.17221/21/2025-CJAS

In this study, the influence of microclimatic conditions in different seasons of the year (including the hottest months) on the quantitative and qualitative characteristics of ejaculates of Czech Holstein bulls was assessed. Bulls were kept in the facility with no forced ventilation or air conditioning. To determine the influence, the temperature-humidity index (THI) was calculated based on the microclimatic parameters measured directly in the facility with the animals. Bull sperm was obtained using an artificial vagina on five occasions throughout the year, in different seasons of the year including the hottest months. Semen was assessed for...

Relationships among clinical mastitis test-day records, somatic cell counts, and linear udder conformation traits in Czech dairy cowsOriginal Paper

Jan Vařeka, Ludmila Zavadilová, Matúš Gašparík, Miloslava Štípková, Luboš Vostrý

Czech J. Anim. Sci., 2025, 70(4):130-138 | DOI: 10.17221/12/2025-CJAS

This study evaluated test-day records of clinical mastitis (CM), somatic cell count, and nine udder conformation traits. Somatic cell count was log-transformed into somatic cell score (SCS) in 10 periods, each 30 days long and overall, for the first lactation. CM is a complex disease closely connected with somatic cell count. The optimum udder conformation traits significantly affect dairy cattle health. The CM binary trait was monitored in seven periods throughout lactation, each 50 days long, and for the whole lactation. A logistic regression model was used to estimate the risk of CM. The model included a fixed effect of herd-year-season, age...

Mesobiliverdin IXα-enriched microalgae feed improves gut health in weaned piglets under LPS challengeOriginal Paper

Czech J. Anim. Sci., 2025, 70(4):139-146 | DOI: 10.17221/159/2024-CJAS

This study aimed to evaluate the effect of mesobiliverdin IXα-enriched microalgae (MBV-SP) on growth, diarrhoea prevalence, intestinal morphology, antioxidant capacity, and inflammatory cytokines in lipopolysaccharide (LPS)-induced enteritis in weaned piglets. Seventy-two 28-day-old piglets were randomly divided into four groups: control (NC), LPS, tylosin, and MBV-SP, with saline/LPS (100 µg/kg) administered intraperitoneally on day 14. Results showed reduced mortality and diarrhoea rates in the tylosin + LPS and MBV-SP + LPS groups compared to the LPS group. Histological analysis revealed improved villus morphology and decreased crypt...

Effects of low-protein diet supplemented with exogenous protease on growth performance and intestinal health of broiler chickensOriginal Paper

Xin Hao, Guifeng Zhang, Yilin Ge, Jie Wang, Weiren Yang, Lijie Yang

Czech J. Anim. Sci., 2025, 70(4):147-159 | DOI: 10.17221/18/2025-CJAS

This experiment was conducted to study the effects of low-protein diet supplemented with exogenous protease on performance and intestinal health of broilers. A total of 560 one-day-old male Arbor Acres broiler chickens were randomly divided into 5 treatments with 8 replicates (12 birds per replicate) in a completely randomised design. The treatments were as follows: (1) maize-soybean meal basal diet (CON); (2) negative control with crude protein being 1% lower than in CON (NCON); (3) NCON + 12 000 U/kg coated alkaline protease (NCAP); (4) NCON + 16 000 U/kg alkaline protease (NAP); (5) NCON + 16 000 U/kg keratinase (NKA). The remaining 80 birds (10 replicates,...
