SUMMARYA study was made of the effect on body composition of growing Angus steers from 300 to 440 kg at three different rates. The rates were: High (H) 0·8 kg/day, Low (L) 0·4 kg/day and High-Maintenance (HM) 0·8 kg/day followed by a period during which body weight was maintained constant.The animals were individually penned and the different growth ...

SummaryThe effect of three different growth rates from 15 to 40 kg live weight on the body composition of lambs was studied. The treatments were: High (H) ad-libitum feed intake, Low (L) restricted feed intake and High–Maintenance–High (HMH) ad-libitum feed intake from 15 to 25 kg followed by a 50-day period during which live weight was maintained ...

A computer model to predict empty body weight in cattle from diet and animal characteristics.
Journal of Animal Science, 1992A computer model was developed to predict empty BW in cattle as a function of diet (forage NDF, physical form of forage [hay vs silage and pasture], proportion of dietary concentrates) and animal (full BW) characteristics. The model was empty BW = full BW * (1 - GFILL), where GFILL is gut fill expressed as a fraction of full BW.

The composition and energy content of empty body-weight change in mature cattle
Animal Science, 1984ABSTRACTBody-composition data from 73 non-pregnant, non-lactating cows of five genotypes were used to calculate the composition of empty body-weight change in mature cattle. The composition of empty body-weight change was shown to be dependent on empty body weight, containing more fat and less water, protein and ash at higher empty body weights.

SUMMARYEmpty body (EB) composition data from 146 lactating Holstein–Friesian dairy cows were analysed, with cows selected from a large herd to represent a wide range of animal factors including parity, live weight (LW), body condition score (BCS), milk yield and stage of lactation.

We developed methods to integrate two published models that partitioned gains in empty body weight (EBW) to fat and fat-free matter. These models were based on separate mathematical formulations for growing and mature cattle. We assumed that as cattle grow from birth to maturity a transition would occur at some point in the life cycle from the growing ...

SUMMARYFlocks of 9-month-old Merino and Border Leicester & Merino sheep were sampled over the full range of body weights present within flocks. Six pairs of ewes and wethers of equal body weight were taken. The sheep were weighed and slaughtered after a 36 h fast. Total weights of blood, skin, head, feet, internal organs and carcasses were obtained
