This study was conducted to evaluate the effect of feed restriction on body weight, body weight gain, feed intake, and feed conversion ratio and carcass traits of broilers. Two hundred and forty one day old Hubbard broiler chicks were randomly distributed into five treatments. Each treatment included six replicates of 8 birds each. The five treatments were as follows: T1( birds were fed continu...

The data from 27 male Tellicherry goats and 10 female Tellicherry goats maintained at the Livestock unit of Tamilnadu Agricultural University were taken for the study (Coimbatore, India). The goats were maintained as per the routine feeding and management practices of the farm. The average birth weight recorded was 2.62±5.04 Kg for male and 2.34 ± 0.72 Kg for female kids. The average body weigh...

diabetes is a metabolic disorder which affects whole body systems including reproductive system. diabetes is also a contributing factor to infertility. metformin is one of the most common drugs to control hyperglycemia. in this study, 36 adult sprague-dawley female rats (170-210 g) were divided into 3 groups (control, diabetic and diabetic-treated by metformin). in second and third groups, diab...

background: malnutrition is one of the most common hazards which compromise children’s health. previous studies have reported high rates of malnutrition in kohkilouyeh and boyer ahmad. objective: this study was conducted to evaluate the frequency of child malnutrition in yasuj and to explore the association between family characteristics and malnutrition. methods: data were collected from healt...

background: considering the importance and prevalence of obesity and the desire to lose weight, especially among women, this study intended to investigate the relationship between body mass index, body satisfaction, and weight control behavior among women employees in isfahan. methods: an analytical cross‑sectional study was conducted among 408 women who were selected by stratified random sampl...

Body weight is one of the most important quantitative traits with high heritability in chicken. We previously mapped a quantitative trait locus (QTL) for body weight by genome-wide association study (GWAS) in an F2 chicken resource population. To identify the causal mutations linked to this QTL, expression profiles were determined on livers of high-weight and low-weight chicken lines by microar...

Bone density (BD) is an important factor in osteoporotic fracture risk in humans. However, BD is a complex trait confounded by environmental influences and polygenic inheritance. Sheep provide a potentially useful model for studying differences in BD, as they provide a means of circumventing complex environmental factors and are a similar weight to humans. The aims of this study were to establi...

The current research was conducted to estimate the heritability coefficients and the genetic correlations for performance and carcass and body composition traits in a single sire broiler line. The performance traits analyzed were BW at 38 d, ultrasound records of pectoral muscle depth, feed intake, feed conversion ratio, and BW at 42 d. The carcass traits analyzed were eviscerated BW, breast we...

We present genetic analyses of murine weight loss during dietary restriction (DR) for females eating 60% ad libitum (AL). We examined 5 cohorts across 81 different strains (22 strains tested twice) that included the LXS and LSXSS recombinant inbred strains, the LXS parental strains ILS and ISS, and the classical inbreds 129S6, A, BALB/c, C57BL/6, C3H, and DBA. Weight loss exhibited highly signi...
