Th e bio-economic approach was used to calculate economic weights for twelve production (dairy and growth), functional and carcass traits of Slovak Pinzgau cattle raised in dairy (A) and cow-calf (B) system. Th e breeding heifers for own herd replacement with ten reproduction cycles at maximum was produced. Th e sale of surplus male and female calves was assumed aft er fi nishing of weaning per...

The aim of this study was to identify factors influencing profitability in a feedlot environment and to estimate genetic parameters for and between a feedlot profit function and productive traits measured in growth tests. The heritability estimate of 0.36 for feedlot profitability shows that this trait is genetically inherited and that it can be selected for. The genetic correlations between fe...

Depression is often associated with many adverse health conditions and lower socio-economic status. Stressful conditions like presence of disability coupled with traditional negative societal attitude towards disability may result in higher level of depression in the individuals with disability than in general population and can cause other health problems as well. Therefore, the purposes of th...

Data on 324 Holstein bulls from the July 1983 USDA Sire Summary and Holstein Association type evaluations were analyzed using multiple regression to determine which traits or combination of traits in a sire evaluation are most important in determining the price of a straw of semen. Over all bull studs, type was a major economic influence in determining price of semen. When bulls with outlier pr...

The aim of this study is study the inheritance of economic traits in an Iranian Native chickens population by estimating genetic parameters (heritability, genetic, phenotypic and environment correlations) under short-term selection in breeding programs. Identification of genes determining the expression of economically important traits of plants and animals is a main research focus in agricultu...

The popcorn breeding program of Universidade Estadual do Norte Fluminense Darcy Ribeiro aims to provide farmers a cultivar with desirable agronomic traits, particularly with respect to grain yield (GY) and popping expansion (PE). We evaluated full-sib families from the seventh cycle of recurrent selection and estimated the genetic progress with respect to GY and PE. Eight traits were evaluated ...

Beef cattle breeding programs focus on improving important economic traits, including growth rates, and meat quantity and quality. Molecular marker-assisted selection based on genetic variation represents a potential method for breeding genetically improved livestock with better economic traits. Smoothened (SMO) protein is a signal transducer that contributes to the regulation of both osteogene...

Variance components were estimated and relative economic importance of bovine respiratory disease (BRD) was derived from 3 yr of performance, morbidity, and mortality data collected from a single beef cattle finishing operation. One thousand one hundred eighty nine of 12,812 Charolais-sired calves were treated for BRD during the finishing period. Weaning weight (WW), DMI, days to harvest (D2H),...
