The aim of this study was to evaluate MYH7 single nucleotide polymorphism (SNP) (NC_010449.4: g.7:75667956G>A) in relation to growth and carcass traits in pigs reared in Poland. Previous study has shown that g.7:75667956G>A substitution in pigs influences miR-208b and MYH7 expression, and is associated with proportion of muscle fibre types. The presented study was conducted on 582 pigs belonging...
α-Lactalbumin (α-LA) is one of the most abundant milk whey proteins among different mammalian species including domestic horse. The aim of this study was to screen for polymorphism in the 5’-flanking region of the equine α-LA (LALBA) gene and to assess the potential relationship of particular genotypes with LALBA gene expression variability (measured at the mRNA and protein levels) and with basic...
The objective of the study was to investigate the metabolic, health and production consequences of selected pre-calving feeding strategies. Forty Polish Holstein-Friesian multiparous dairy cows were dried off at day 56 before parturition and assigned to 2 pre-calving treatments: CON – a 5-week far-off period and a 3-week close-up period, and SHORT – a 7-week far-off period and a 1-week close-up period...
The aim of the study was to evaluate the effect of copper (Cu) level in the diet on the distribution, and biological and immunological responses in a rat model. Two experimental groups of rats received a diet containing the recommended (higher) amount (6.5 mg/kg) of CuCO3 (CuH) or a diet containing the reduced (lower) level of Cu (without CuCO3 supplementation; CuL) for 7 or 35 days (T7 and T35, respectively;...
The aim of the study was to evaluate in what manner rumen bacterium Pseudobutyrivibrio ruminis strain k3 uses and ferments timothy grass fructan, inulin, inulooligosaccharides, sucrose, fructose and glucose. The highest concentration of bacterial population was noted at 12 h of incubation for all cultures except from that on fructose which occurred at 24 h. The highest specific growth rates occurred...
It is thought that mares being 20 years old can still give birth to foals, some individuals are even longer capable to be pregnant. However, each year mare owners should realize that the older mare the more decreased horse fertility. An aged mare that has recently had a foal has a greater chance to become pregnant again than a mare of similar age that has remained barren despite being bred over multiple...
The aim of the study was to evaluate the effect of dietary inclusion of dried olive pomace (DOP) on proteolytic volatile compounds in raw milk and pasteurised milk cheese. Two groups of lactating cows (20 animals in each) were randomly assigned to isoenergetic and isoproteic treatments provided as control mixed ration (CON) and as CON with addition of 2 kg of DOP/day/animal (EXP). DOP partially replaced...
Iron (Fe) is ubiquitous in the environment and has possible impact on quality and safety of feed and food due to the fact that it can be transferred from soil to animal feed and further to the products of animal origin. Therefore, the objective of the present study was to evaluate the effect of contamination of forage with soil differing in Fe concentration on Fe solubility, mineral composition and...
The aim of the experiment was to evaluate the effect of different incubation temperatures on hatchability, embryonic development and physiological responses of chicks produced from hens treated with bee pollen (BP). In total, 600 Sinai hatching eggs were equally collected from hens treated with 0, 500, 1000 and 1500 mg BP/kg diet (four dietary groups) and then divided into two equal incubation groups...
Allelic and genotypic distributions of polymorphisms in the uncoupling protein 3 (UCP3) and forkhead box O1 (FOXO1) genes were assessed in 491 Chinese Qinchuan cattle. Single-locus genotype effects and the combined effect of polymorphisms within those two genes were probed to determine possible association with the carcass quality traits. Using DNA sequencing, in total three novel single nucleotide...
