Endometrium receptivity, an absolutely necessary part of successful embryo implantation, and several morphological and biochemical endometrial receptivity biomarkers have already been studied and proposed in some animals. However, to our knowledge, no such a study has as yet been undertaken in dairy goat. In the present study, the serum and uterus of dairy goat were studied at gestational days 5 and 15, the estrogen (E2) and progesterone (P4) concentrations in serum were determined by electrochemiluminescence immunoassay, the surface topography of endometrium was observed by scanning electron microscopy. Furthermore, the estrogen receptors (ER),...

The purpose of the study was to evaluate the amount of raffinose-series oligosaccharides (RSO) in soybean meal (SBM), whole white lupin seed meal (WLM), sunflower meal (SFM), and rapeseed oil meal (ROM) and to determine whether partial or complete dietary WLM replacement affected the numbers of bacteria in selected groups in the microbiota of broiler chickens and ducks without inducing any weight loss. Total counts of anaerobes, lactobacilli, bifidobacteria, and Escherichia coli in caecal samples from both ducks and broiler chickens, as well as in a crop chyme, in broiler chickens, were determined. Live weights before slaughter were determined....

The differences in egg production traits in six laying hen genotypes (brown-egg hens Bovans Brown, Bovans Sperwer, ISA Sussex; white-egg hen Dekalb White; laying hens with tinted shells Moravia Barred and Moravia BSL) and the interactions of genotype and oviposition on egg quality were evaluated. The genotype affected the laying rate (P ≤ 0.003), mean sequence length (P ≤ 0.001), and time of oviposition (P ≤ 0.001). The brown-egg genotypes laid eggs approximately 1 h earlier than the white-egg genotypes and approximately 2 h earlier than the tinted-egg genotypes. Egg shell strength was the lowest in tinted-egg genotypes...

The objectives were to evaluate polymorphism in ten microsatellite markers and to demonstrate their association with milk production traits in the Egyptian buffaloes, based on the cross-species transferability of microsatellites from cattle to buffalo. A total of 17 439 daily milk records from the first five lactations were subjected to analyses, in which records from 5 to 290 days in milk were only included. The analysis revealed that eight out of the ten bovine markers analyzed were polymorphic. The means of the number of alleles, effective number of alleles, and fixation index within markers were 4.125, 2.479, and 0.062, respectively. The means...

Czech J. Anim. Sci., 2017, 62(9):392-402 | DOI: 10.17221/11/2016-CJAS  

The aim of the present investigation was to evaluate how the order in which the ewes in a milking group enter the milking parlour affects their milkability and milk composition. Therefore, the order of entry into the milking parlour was evaluated in ewes of one flock (n = 353) during six evening milkings. In all, the sheep were milked in 15 milking groups. The sheep entering the milking parlour in the first milking group achieved 15 points and the sheep of each next milking group one point less, i.e. the sheep of the last group achieved 1 point. In the analysis, only the ewes with the highest and the lowest average number of points were included...
