Daily feeding regimen impacts pig growth and behavior

Intensified Pre-Weaning Calf Feeding Programs: Impacts on Growth and Behavior

There are a range of viewpoints on how best to feed and manage dairy calves early in life. Traditional approaches to rearing dairy calves have focused on stimulating early solid feed intake through restricting intake of milk or milk replacer. A conventional milk feeding rate is approximately 10% of a calf’s birth weight, an amount that translates to between 4 and 5 L/day, supporting under 0.5 k...

Impacts of Sugar Feeding on Parasitoid Behavior in the Field

Diversifying agroecosystems with floral habitats has the potential to conserve natural enemies and enhance pest control. In the laboratory, many adult parasitoids readily utilize nectar sources that have substantially increased their longevity and parasitism rates. However, in the field, does the floral habitat retain parasitoids locally so they exert greater control on pests? We studied the po...

VENTROMEDIAL HYPOTHALAMIC NUCLEI AND FEEDING BEHAVIOR

The role of the ventromedial nuclei of the hypothalamus (VMN) in food behavior was studied in adult male rats, allocated in 3 groups: control, sham and lesioned. Electrolytic lesions were induced stereotaxically (1.2 mA, 15 sec). Results revealed a significant decrease (p<O.05) in body weight (BW) and food intake (FI) in the order of lesioned <sham <control during the fIrst week. However, ...

Effects of gender, time of castration, genotype and feeding regimen on lamb growth and carcass fatness.

Two concurrent trials were conducted to examine the effects of gender, time of castration, genotype and feeding regimen on lamb growth rate and carcass fatness. Trial 1 compared Polypay and Coopworth x Polypay male lambs either left intact or castrated early, mid or late in growth. Trial 2 compared Hampshire-sired lambs (females, early castrate wethers and late castrate wethers) from Suffolk x ...
