the objectives of this study were to identify a suitable mathematical model for describing the growth curve of baluchi sheep based on monthly records of live weight from birth to yearling; and to evaluate the efficacies of nonlinear mixed effect model (nlmm) and the nonlinear fixed effect model (nlm) methodologies. growth models were fitted to a total of 16,650 weight–age data belonging to 2071...

background: obesity is an important and life-threatening disease, associated with different chronic conditions such as cardiovascular disease, diabetes, and dyslipidemia. we sought to address the paucity of information on the trends of anthropometric indices such as weight, waist circumference, and body mass index in the adult population of iran. methods: we drew upon data from the first non-co...

background: polycystic ovarian syndrome (pcos) represent one of the common endocrine disorders which influence around 8% of reproductive women whom usually suffering from obesity and increase cardiovascular risk. serum homocysteine levels are associated with bad impact on endothelial functions and considered as an independent risk factor for cardiovascular disease. objective: the aim was to stu...

this experiment was carried out to investigate the effects of in yolk-sac administration of olive oil (0 and 0.7 ml) on productive performance and breast development of broiler chickens exposed to post-hatch fasting stress (0, 12, 24, 36 and 48 hours). a total number of 800, 1-day-old broiler chicks in a completely randomized block design with 10 treatments and 4 replicates were used. live body...

OBJECTIVE To determine trends in weight, height, and body mass index in children between 1989 and 1998. DESIGN Retrospective series of cross sectional studies of routinely collected data. SETTING Primary care in the Wirral Health Authority. PARTICIPANTS 35 662 infants aged 1-3 months (representing 88% of live births) and 28 768 children aged 2.9-4.0 years. 21 582 infants and children (25....

This study was carried out to investigate the effect of humic acids (HA) supplementation provided through drinking water on performance, carcass and some gut traits of broilers. In a randomized design, 480 mixed-sexes Ross 308 broilers were allocated into four experimental groups consisted of four replicate (30 birds per replication). All birds were housed in pens over 42 day. All chickens were...

A 4-year study comparing Hereford × Friesian (HF) and Limousin × Friesian (LF) spring-calving cows and two grass silages on the performance of suckler cows and their progeny was undertaken using 163 cows. Cows were offered, to appetite, grass silage of either low (L) or moderate (M) digestibility in late pregnancy and early lactation. Cows and their calves spent from April until weaning in Octo...

background: in pediatric resuscitation, it is necessary to distinguish the weight in order to provide proper doses of drugs, equipment selection, and ventilator settings, therefore, access to a simple, unbiased, and accurate formula can decrease mistakes. the aim of this study is to determine the percentage of error (pe) of different weight estimation methods toward actual weight in children  a...

the objective of this study was to determine the effect of different levels of chicory root and stem powder (crsp) and butyric acid (ba) combination on the performance, carcass traits, relative weight of internal organs and some blood parameters in broiler chickens. two hundred and forty one-day-old broilers (ross 308) were used in a completely randomized design with four treatments with six re...
