Effect of increasing energy and protein intake on body growth and carcass composition of heifer calves.
TLDR
Increasing energy and protein intake from 2 to 8 wk and 8 to 14 wk of age increased BW, withers height, and gain:feed ratio, and Plasma IGF-I concentrations were greatest for calves fed the H diet during either period. Expand
Physical characteristics, blood hormone concentrations, and plasma lipid concentrations in obese horses with insulin resistance.
TLDR
Measurements of neck circumference and resting insulin and leptin concentrations can be used to screen obese horses for IR and Dyslipidemia is associated with IR in obese horses. Expand
Polymorphisms in the bovine leptin promoter associated with serum leptin concentration, growth, feed intake, feeding behavior, and measures of carcass merit.
Leptin is the hormone product of the obese gene synthesized and secreted predominantly by white adipocytes. It functions as a lipostatic signal regulating BW, food intake, energy expenditure,Expand
Leptin in horses: tissue localization and relationship between peripheral concentrations of leptin and body condition.
TLDR
It is concluded that leptin and leptin receptors are present in equine tissues and that peripheral concentrations of leptin reflect a significant influence of fat mass in Equine. Expand
The relationship between mitochondrial function and residual feed intake in Angus steers.
TLDR
It seems that mitochondrial function is not different between the high and low RFI groups but rather the rate of mitochondrial respiration is increased in low R FI steers compared with high RFI steers. Expand
Influence of body condition at calving and postpartum nutrition on endocrine function and reproductive performance of primiparous beef cows.
TLDR
Concentrations of IGF-I and leptin in plasma were constant during 7 wk before the first estrus, indicating that acute changes in these hormones are not associated with the resumption of ovarian function in primiparous beef cows. Expand
Plasma leptin determination in ruminants: effect of nutritional status and body fatness on plasma leptin concentration assessed by a specific RIA in sheep.
TLDR
Data provide strong evidence that, in sheep, the variations in plasma concentrations of leptin are related to variations in body fatness and, to a lesser extent, in nutritional status. Expand
Follicular function in lactating dairy cows treated with sustained-release bovine somatotropin.
TLDR
Serum concentrations of bST and insulin-like growth factor I were lowest during saline injections and increased after bST injections, while Peak concentrations of serum FSH were lower and occurred earlier for the cows treated with bST. Expand
Effects of controlled heat stress on ovarian function of dairy cattle. 1. Lactating cows.
TLDR
Conclusions were that follicular growth and development and luteolytic mechanisms were compromised in heat-stressed cows; as a result, lutelysis was delayed, and second wave dominant follicles did not ovulate. Expand
Programming of glucose-insulin metabolism in adult sheep after maternal undernutrition.
TLDR
Pregnant undernutrition, specifically during late gestation, affects adult offspring intermediary metabolism, and, in particular, glucose-insulin homeostasis in sheep, which was unaffected by fetal number. Expand
