QTL in Cattle PHENOTYPE DEFINITION AND THE IDENTIFICATION OF QTL FOR PUBERTY TRAITS IN CROSSBRED DAIRY CATTLE
نویسندگان
چکیده
Onset of puberty was measured in 850 F2 Friesian x Jersey animals in a QTL discovery trial. Phenotypes for onset of puberty were defined by age at puberty based on endocrine profiles, and predicted proportion of mature live weight. A QTL analysis was conducted on the derived phenotypes using line of descent and half sib regression models. Results from the proportion of estimated mature live weight at puberty analysis suggested putative QTL on chromosomes 5,6,7,11 and 16.

Genetics of resistance to mastitis in dairy cattle.
Genetic variability of mastitis resistance is well established in dairy cattle. Many studies focused on polygenic variation of the trait, by estimating heritabilities and genetic correlation among phenotypic traits related to mastitis such as somatic cell counts and clinical cases. The role of Major Histocompatibility Complex in the susceptibility or resistance to intrammamary infection is also...
متن کاملReproductive Performance Definition in Dairy Cattle: Affective Factors
The reproductive performance of a dairy herd has a significant effect on the profitability of that herd. Common measures of reproductive performance are days to first service, days to conception, calving interval, services per conception, conception rate, estrus detection rate, and pregnancy rate. Most cow operations would benefit economically by reducing the number of operational days, decreas...

Emphasis on milk yield (MY) as well as milk yield persistency (MYP) and calving interval (CI) is necessary to achieve more sustainable productionin dairy cattle. Therefore the main objective of this study was to find an optimum regression model to estimate economic values for MY, MYP and CI.Using a deterministic bio-economic model, seventyfiveproduction states differing mainly in MY, MYPand CIw...
متن کاملQuantitative trait loci for apolipoprotein B, cholesterol, and triglycerides in familial combined hyperlipidemia pedigrees.
OBJECTIVE Familial combined hyperlipidemia (FCHL) is a genetically complex lipid disorder that is diagnosed in families by combinations of increased cholesterol, triglycerides, and/or apolipoprotein B (apoB) levels in patients and their first-degree relatives. Identifying the predisposing genes promises to reveal the primary risk factors and susceptibility pathways and suggest methods of preven...
