Evaluation of the accuracy of simple body measurements for live weight prediction in growing-finishing pigs
… of simple body measurements to predict the live weight of growing-finishing pigs. Study I used 72 barrows from a Landrace-based line; Study II used 72 barrows from each of a Landrace-based (the same line as used in Study I) and a Duroc-based line. Study I was carried out between 57.5 ± 7.1 …

Modeling growth of pigs reared to heavy weights
… conducted to determine the relationship between live weight and growth performance measures of pigs reared to heavy weights in commercial facilities and to evaluate different methods of modeling these relationships. The first study was designed to develop growth curves of live animal growth …

The effect of early-pregnancy nutrition on lamb birth weight in fecund Booroola-Merino cross sheep
The effects of ewe nutrition and live weight change during early-pregnancy on lamb birth weight were studied. 218 Booroola cross Coopworth ewes carrying at least one copy of the F gene were stratified according to live weight, breed and age, and randomly allocated to a high(H), medium (M) or low …

Effects of sprouted cowpea (vigna unguiculata) dietary inclusion with ronozyme ® ProAct supplementation on broiler performance
… supplementary exogenous enzymes on the growth (live weight, live weight gain, feed conversion ratio) and carcass parameters of Ross-308 broilers. Cowpeas were screened for viable seed and sterilised by 30-minute immersion in 2% sodium hypochlorite aqueous solution. Germinated by 12-hour soaking …

The effects of the rate of gain during four periods of growth on carcass characteristics in swine
… statistically significant association with the live weight groupings as arbitrarily designation. The carcass length was inconsistently and statistically nonsignificantly related to the live weight. Sex of the animal did effect the carcass in that gilts had leaner carcasses than barrows as shown …

Lamb wastage and its association with ewe body condition
The effect of ewe body condition and live weight, and change in these factors, on lamb wastage was examined in a composite (principally Coopworth) flock of small- or large-framed ewes. Approximately equal sized flocks of small- and large-framed ewes, balanced for age and condition were selected …

A feasibility study for the sale of cultured catfish in Virginia and Washington, D.C.
… estimated to be around 4,244,000 pounds (dressed weight) annually. The net returns generated by the two fish farm enterprises studied ranged from -$63.49/1.5 acre to $189.53/1.5 acre and the rates of return ranged from -8.9% to 27.4% at a $.30 per pound (live weight) price level. The present fish …
