Changes in the oxidative - biochemical status in dairy cows during the transition period affecting reproductive and health parameters.Review

Czech J. Anim. Sci., 2024, 69(9):345-355 | DOI: 10.17221/128/2024-CJAS

Negative energy balance (NEB) after calving leads to unique metabolic changes in cows and it provides important information on the period when nutrient output prevails over nutrient intake associated with a number of physiological changes in the organism suitable for detection using biochemical blood analyses. The aim of this paper is to summarise current knowledge of the changes in blood parameters during the period of NEB in relation to non-esterified fatty acids, ketone bodies, and immunologic and stress indicators. The impact of these changes on bovine reproduction and health is also discussed in the sequel. The period of NEB is still...

Optimising the feed composition, especially the forage choice, and reducing costs are essential for improving dairy production efficiency. Different forage sources and proportions were used to formulate rations containing equal energy and protein, and their effects on rumen microbiota and milk production performance of dairy cows were evaluated in two experiments. In experiment 1, thirty lactating cows (235 ±13 d postpartum; milk production 29.1 ± 1.0 kg/day) were divided into Pangola and Bermuda groups. In experiment 2, twenty lactating cows (79.9 ± 8.1 d postpartum; milk production 34.7 ± 0.6 kg/day) were divided into...

Livestock farming is vital to a country's economy, and technological innovations in animal genetics and reproductive biotechnologies are key for environmental and socioeconomic development. This study aimed to evaluate the antioxidant capacity of Coffea arabica grounds (CAG) extract on the semen parameters of Fleckvieh cattle. CAG was processed, and its antioxidant capacity was assessed using DPPH, FRAP, and total phenols assays. Semen was collected from a pedigree bull and analysed macroscopically and microscopically. Different concentrations of CAG (0, 1, 1.5, and 2 mg/ml) were tested at 4, 12, 24, and 36 h post-refrigeration. The study...

Does the incidence of egg yolk influence the meat quality and fatty acid profile of broilers of two chicken genotypes?Original Paper

Czech J. Anim. Sci., 2024, 69(9):378-387 | DOI: 10.17221/122/2024-CJAS

The present experiment studied the effects of egg composition (egg yolk content; Y) of two different chicken genotypes (selected by computed tomography; CT) on hatched chick growth performance, slaughter traits, and meat quality. Three thousand five hundred eggs per genotype were scanned by CT. Then, for each genotype, eggs were selected according to their Y content: low (21.0 ± 0.88 – 350 eggs), medium (24.5 ± 0.15– 350 eggs) and high (28.3 ± 0.98 – 350 eggs). The remaining eggs were excluded from the study. At 11 weeks of age, 15 chickens per group were slaughtered, carcasses were dissected and breast and legs...
