The large inter-individual variation in weight gain during standardized overfeeding together with a weight gain that is often less than theoretically calculated from the energy excess suggest that there are differences between persons in the capacity to regulate energy expenditure and hence metabolic efficiency. Adaptive thermogenesis is defined as the regulated production of heat in response t...

BACKGROUND Promoting catch-up growth in malnourished children has health benefits, but recent evidence suggests that accelerated child weight gain increases adult chronic disease risk. OBJECTIVE We aimed to determine how birth weight (BW) and weight gain to midchildhood relate to blood pressure (BP) in young adults. DESIGN We pooled data from birth cohorts in Brazil, Guatemala, India, the P...

The weight records from Simmental beef cattle were used in a genetic evaluation of growth with or without the inclusion of animals obtained by embryo transfer. A multi-trait model in which embryo transfer individuals were excluded (MTM1) contained 29,510 records from 10,659 animals, while another model without exclusion of these animals (MTM2) contained 62,895 weight records from 23,160 animals...

Feeding trial was conducted on sixty day-old Anak broiler chicks of average weight of 204.11+3.29g for eight weeks to evaluate the effect of sun-dried paw-paw leaf meal (PLM) on their growth performance as well as proximate composition analysis on the PLM. The birds were assigned to four treatment diets comprising T1 (0% PLM), T2 (5% PLM), T3 (10% PLM) and T4 (15% PLM) in a completely randomize...

Genetic parameters for traits related to postweaning growth in Braunvieh cattle, reared under tropical and sub-tropical conditions in Brazil, were studied. Weight traits were weight at 365 days of age (W365, N = 4055), at 450 days (W450, N = 3453), and at 550 days (W550, N = 1946), while weight gains were gain from weaning to 365 days of age (WGW365, N = 3060), from weaning to 450 days (WGW450,...

Mass selection for increased weight at 200 d of age was conducted for six generations in a line of Duroc pigs. A randomly selected contemporary control line was maintained. Our objectives were to observe the response in 200-d weight, to measure correlated responses in weights at earlier ages, daily gains and ultrasound backfat thickness and to compare three methods for estimating responses to s...

The incorporation of lucerne meal in the diet of chicks prevents normal gains in weight (Alder, 1946; Draper, 1948; Cooney, Butts & Bacon, 1948; Lepkovsky, Shaeleff, Peterson & Perry, 1950; Heywang, 1950; Kodras, Cooney & Butts, 1951 a, b). This effect is attributed to the saponin fraction of lucerne (Peterson, 195oa, b; Heywang & Bird, 1954), which has been shown to be a complex mixture of rel...
