The dietary patterns and extent of overweight in 307 urban school going children aged 7 to 15 years representing various socio-economic strata was evaluated at baseline of a 3 year longitudinal study. Dietary habits were recorded through interviewer-administered questionnaires. Height and weight were measured and 8.2% of the children were over-weight or obese. Children from higher socio-economi...

this study was evaluated some strategies and determined the suitable selection index for afshari sheep using simulated data. the relative importance of traits was determined based on the estimated economic values and consequently, the most benefit traits were applied to selection indexes construction. the interest indexes were different combination of traits including ewe body weight (ebw), ann...

A new model was developed to provide Australian pig breeders with an ability to estimate economic values and economic weights of key traits in a way that was more flexible and relevant to pig producers. Economic weights were converted using a genetic standard deviation scalar so that the relative contributions of each trait to the overall maternal breeding objective could be made. Number of pig...

Low birth weight (LBW) is a major contributor to infant mortality. Beyond that, reducing low birth weight could result in appreciable economic benefits. The present paper considers the potential benefits from reducing low birth weight in seven distinct categories: 1. Reduced infant mortality; 2. Reduced neonatal care; 3. Reduced costs of infant/child illness; 4. Productivity gain from reduced s...

Profit was defined as a function of the genotype of animals and variables controlled by management. Alternative parameterizations of management variables were examined to compare the effect of controlling age at slaughter, weight at slaughter, or fat depth at slaughter. The various parameterizations are shown to result in equivalent economic weights for genetic variables, provided management va...

This paper proposes a dynamic comprehensive evaluation method based on three times weight. Firstly, this paper determines the index weight based on the twice stage difference driving features. Then it introduces the relative balance coefficient to calculate the comprehensive evaluation value. This method has the following characteristics: 1) The comprehensive evaluation result is totally based ...

the present investigation aimed to conduct a genetic study of dairy cattle and buffalo bulls based on economic traits and their phenotypic correlation. the means of various economic traits in both the species are presented. cattle bulls reported a better libido score, flehmen response, requirement of mounting stimulus and semen volume, conception rate and expected predicted difference for milk ...

Heritabilities (ĥ2) and genetic correlations (rG) were estimated by regression of offspring on sire in two replicate, unselected lines of mice. Traits were associated with growth, feed efficiency, fat deposition and lean tissue. The ĥ2 for growth traits ranged from .34 to .42, except for 3-wk body weight, which was only .05. The ĥ2 for feed efficiency was .28. Ranges in ĥ2 were .45 to .50 for f...
