Corpus luteal angiogenesis in a high milk production dairy breed differs from that of cattle with lower milk production levels
Holstein Friesian dairy cows dual purpose cows corpus luteum vascularisation capillary angiogenesis
2016/10/14
Globally, high producing, young dairy cows often have health and fertility problems such as ovarian, uterine and placental dysfunction, mastitis and impaired wound healing. These health issues can res...
Production value and cost-effectiveness of pig fattening using liquid feeding or enzyme-supplemented dry mixes containing rye grain
swine barley fattener enzyme yeast xylanase
2016/9/1
The aim of this study was to assess the cost-effectiveness of a fermented liquid feeding and enzyme supplementation of dry fodders containing rye grain for pig fattening. Two experiments were performe...
Effect of the FGF2 SNP11646 on milk production and fertility traits of Holstein cattle
dairy cow fibroblast growth factor single nucleotide polymorphism linear mixed model
2016/9/1
The objective of this study was to estimate the effect of a single-nucleotide polymorphism (SNP11646) in the FGF2 (Fibroblast Growth Factor 2) gene on the deregressed proof of breeding values (DRP) of...
In-feed supplementation of clinoptilolite favourably modulates intestinal and systemic immunity and some production parameters in weaned pigs
clinoptilolite immunomodulation performance bacterial counts piglet
2016/7/6
The ban on dietary antibiotic growth promoters (AGP) in swine production has focused increasing research efforts on the development of alternative feed supplements. One such alternative to AGP is the ...

monochromatic lights production performance microbial contamination laying hens
2015/12/17
The objective of this study was to compare the performance of laying hens, quality of air in poultry house, and microbial contamination of eggshell in laying hens kept under blue, green, red, and yell...
Effect of genotype on heat production and net energy value of a corn-soybean meal-based diet fed to growing pigs
energy utilisation genotype growing pigs heat production net energy
2015/10/9
The net energy (NE) system takes into account the metabolic utilisation of energy and has been proposed as a superior system for characterising the energy value of feeds. In growing pigs, the ineffici...
Effects of supplementing vitamin E on in vitro rumen gas production,volatile fatty acid production,dry matter disappearance rate,and utilizable crude protein
vitamin E rumen fermentation in vitro
2015/9/15
Two in vitro trials were carried out to study the effects of supplementing vitamin E (VE) on rumen fermentation. In Trial I, four levels of VE product (purity 50%), i.e. 0, 15, 30, and 60 mg/kg dry ma...
Effects of chitosan on nitric oxide production and inducible nitric oxide synthase activity and mRNA expression in weaned piglets
serum mononuclear cell small intestine immune function lipopolysaccharide
2015/9/15
The effects of chitosan on nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) activity and gene expression in vivo or vitro were investigated in weaned piglets. In vivo, 180 weane...
Genetic relationship of functional longevity with female fertility and milk production traits in Czech Holsteins
Holstein cattle genetic parameters milk yield functional traits
