Flow cytometry (FC) is a very powerful method for the assessment of spermatozoa quality in multiple livestock species, including bulls. Nowadays, many flow cytometric tests are available for quality detection of bull sperm. These tests are based on fluorochromes (fluorescent tags or dyes) and the use of correct concentrations of fluorochromes is an essential aspect of the successful optimization of experimental methodology. Modern flow cytometers are much more affordable, such that spermatologists are now able to use FC methodology (and even image cytometry) in their studies. The present review aims to give a summary of current flow cytometric methodologies...

The use of genomic data makes it possible to examine genetic variability and calculate the genetic parameters of the population in an efficient and precise way. The aim of this research was to analyse linkage disequilibrium (LD), contemporary effective population size (Nec), haplotype block structure, minor allele frequency (MAF), observed (HO) and expected heterozygosity (HE), calculate the genomic relationship matrix and perform a principal component analysis (PCA) in the Serbian Holstein-Friesian cattle population using SNP data from the GGP Bovine 100K chip. After quality control (QC), 83 208...

To better explore the effects of adding phytosterol (PS) microcapsules to feed on pig growth performance, nutrient apparent digestibility, and serum biochemical indicators, 200 healthy ternary hybrid Duroc × Landrace × Yorkshire piglets with an average initial weight of 7.53 ± 0.57 kg) were used as experimental subjects, and randomly divided into five groups with four replicates in each group. The control group of pigs was fed the basic diet, while the experimental group received diets supplemented with different PS levels. They were divided into experimental groups 1 to 4 (100 mg/kg to 5 502 mg/kg) according to different dosage added components....

The present study aimed to investigate the effect of catalase (CAT) on the growth performance, antioxidation, and microbial metabolism of weaned rabbits. Dietary treatments consisted of control and CAT supplementation at 100 (T1), 150 (T2), and 200 IU/kg of diet (T3). A total of 240 weaned rabbits were randomly assigned to 4 groups with 6 replicates of 10 rabbits each. The feeding trial lasted for 28 days. Results showed that T2 and T3 increased (P < 0.05) body weight gain and gain/feed ratio, and decreased (P < 0.05) diarrhoea rate, compared to the control. Also, serum antioxidative parameters and oxidative stress products were...
