Goat mastitis detection using daily records of milk conductivity: comparative results of different algorithms
intramammary infection gland measurements on-line
2015/7/2
Milk electrical conductivity is employed for mastitis detection in cows due to its automation, low cost, and infection detectability at early stage. Nevertheless, the number of publications about its ...
Domestic and Interbull information in the single step genomic evaluation of Holstein milk production
genomic breeding value single-step prediction animal model
2015/7/2
Estimated breeding values and genomic enhanced breeding values for milk production of young genotyped Holstein bulls were predicted using a conventional animal model, ridge regression genomic predicti...
Analyses of genetic relationships between linear type traits, fat-to-protein ratio, milk production traits, and somatic cell count in first-parity Czech Holstein cows
Holstein cattle genetic parameters milk yield somatic cell score
2015/7/2
Genetic and phenotypic correlations between production traits, selected linear type traits, and somatic cell score were estimated. The results could be useful for breeding programs involving Czech Hol...
Fresh and ensiled forages as a source of estrogenic equol in bovine milk: a review
phytoestrogens isoflavones red clover silage
2015/6/24
Isoflavan equol has recently been assessed in human nutrition as a potent estrogen with various health benefits. It is produced by intestinal microflora from isoflavones (IF) formononetin and daidzein...
Impact of crude protein content in silage and concentrate on protein and fatty acid profiles in bovine milk
milk proteins feed protein clover casein CLA α-linolenic acid capillary electrophoresis
2015/6/24
Two concentrates, one protein-rich and one based on cereals, were combined with two silages with a crude protein content of 17 and 13% of dry matter (DM), respectively to give four different diets for...
Genetic parameters for female fertility and milk production traits in first-parity Czech Holstein cows
dairy cattle reproduction production
2015/6/23
The aim of this study was to estimate genetic parameters for female fertility and production

Changes in the composition of goat colostrum and milk fatty acids during the first month of lactation
milk composition fatty acids serum
2015/6/23
Changes in the composition of colostrum and milk fatty acids during the first month of lactation
of ten 3-years-old White Shorthaired goats fed a winter diet were investigated. Thirty-eight fatty ac...
Estimation of genetic parameters and evaluation of test-day milk production in sheep
dairy heritability model selection
2015/6/23
The fixed effects
were estimated by the least-squares method, while the genetic parameters were estimated by the REML
method. The data were tested by 49 models, but on the basis of the coefficient...
Effect of weaning calves from mother at different ages on their growth and milk yield of mothers
calf cow restricted suckling weaning growth milk production
2015/6/9
The aim of this study was to determine the impact of the length of calf sucking milk from its own mother on calf growth at the age of 3 months and milk yield of mothers. We tested a hypothesis that th...
