The effect of grazing on the productive performance and meat quality was evaluated for chickens
(Ross 308, n = 192). Chickens were kept in two pens on wooden shavings (2 × 96) from one day of age. O...
Effect of synbiotic dietary supplementation on survival, growth performance, and digestive enzyme activities of common carp (Cyprinus carpio) fingerlings
probiotic growth survival digestive enzyme
2015/7/7
The results showed that synbiotic could significantly enhance growth parameters (weight gain, length gain,
specific growth rate, percentage weight gain) (P < 0.05), but did not exhibit any effect on...
Effect of replacing dietary FeSO4 with equal Fe-levelled iron glycine chelate on broiler chickens
broiler amino acid chelated iron
2015/7/7
Xanthione oxidase activity in blood serum showed no significant difference between
all treatments at day 21 except for Experimental group 5 (P > 0.05). In addition, catalase activity in blood
seru...
Changes over time in genetic parameters for growth in bulls and assessment of suitability of test methods
gain genetic analysis progeny test
2015/7/3
Objectives of the study were to examine alternative measures of growth potential of bulls in testing stations, determine whether genetic parameter estimates of such traits changed over time, and exami...
Metabolites of vitamin D and minerals in blood and colostrum of primiparous and multiparous dairy cows postpartum
calcidiol calcitriol calcium
2015/7/3
Concentrations of calcidiol, calcitriol, and minerals in blood serum and colostrum of 14 primiparous and 16 multiparous Holstein dairy cows during short-period prepartum and postpartum were determined...
Estimation of breeding values for functional productive life in the Slovak Holstein population
cattle longevity survival analysis risk ratio
2015/7/3
Genetic evaluation of length of functional productive life was carried out using a Weibull proportional hazard sire-maternal grandsire model. The database included 405 624 Holstein cows with 19.24% ce...
Effect of DGAT1, BTN1A1, OLR1, and STAT1 genes on milk production and reproduction traits in the Czech Fleckvieh breed
cattle genetic polymorphism fertility
2015/7/3
The impact of polymorphism of the diacylglycerol acyltransferase (DGAT1), butyrophilin (BTN1A1), oxidized low-density lipoprotein receptor (OLR1), and signal transducer and activator of transcription ...
Melatonin receptor (MTNR1A and MTNR2B) expression during the breeding season in the yak (Bos grunniens)
domestic yak immunofluorescence MLTR
2015/7/3
Melatonin plays key roles in a wide range of mammalian body functions, which are mediated by the melatonin-specific cell surface receptor (MTNR1A and MTNR1B). To better understand the role of MTNR in ...
Distribution of tetraspanin family protein CD9 in bull reproductive system
monoclonal antibody immunohistochemistry sperm
2015/7/3
The CD9 cell surface molecule has been found to be important for the fertilization process of mammals. The aim of this study was to investigate, whether the molecule CD9 is expressed on bull sperm dur...
Effect of the first and second postpartum partial milking on blood serum calcium concentration in dairy cows
incomplete colostrum milking subclinical hypocalcemia milk fever
2015/7/3
Parturient paresis and subclinical hypocalcemia are frequent metabolic disorders in dairy cows postpartum. The aim of this study was to determine the effect of postpartum partial milking in the first ...
Polymorphism, linkage mapping, and association analysis with carcass traits of four porcine candidate genes selected from gene-expression profiles of Czech Large White and Wild Boar muscles
pig single nucleotide polymorphism DNA markers
2015/7/3
Genes that are expressed in skeletal muscles may play a role in prenatal muscle development and postnatal muscle growth and can be considered candidates for economically important traits. Four porcine...
Composition of major proteins in cow milk differing in mean protein concentration during the first 155 days of lactation and the influence of season as well as short-term restricted feeding in early and mid-lactation
