The effect of supplementing cereal straws with urea, trifolium hay and noug meal on feed intake and liveweight gain of growing crossbred heifers

Compares the effects of noug meal, Trifolium tembense hay and urea, fed in different combinations as supplements to wheat or teff straws, on feed intake and growth rate of crossbred heifers

Past and present research on sheep and goat breeding in Nigeria

Presents the past and present research findings on sheep and goat breeding in Nigeria. Attempts were made in the past at exploiting their genetic potentials through pure breeding and selection while a number of exotic breeds were used on the indigenous sheep and goats to improve goats and sheep skin quality, meat, wool and milk production. The present breeding programme aims at improving growth rate and prolificacy in sheep and goat through pure breeding and selection of the indigenous breeds for skin, meat and milk. Data on reproduction traits, body weight, growth rate, carcass yield, birth weight, lambing and weaning weights included

Economics of commercial beef production under feedlot system of management

Reports an economical and profitable scheme for fattening Sokoto Gudali and Bunaji bulls on a commercial scale at the National Animal Production Research Institute in Nigeria. Bunaji bulls had better performance with respect to average daily gain and carcass dressing percentage but the reverse in the case of carcass composition. Data on all inputs and outputs of the feedlot project included

Compares the effects of noug meal, Trifolium tembense hay and urea, fed in different combinations as supplements to wheat or teff straws, on feed intake and growth rate of crossbred heifers

Carcass characteristics of indigenous breeds of cattle in Nigeria

Bunaji and Sokoto Gudali breeds of cattle were fattened and slaughtered at live weights of 250, 300 or 350 kg. After the carcasses were jointed into commercial cuts, the joints of the left side were dissected into lean, bone and fat. Dressing percentage was significantly higher in Bunaji carcasses (52.5 %) than in Sokoto Gudali carcasses (50.3%). The lean percentage was nearly constant at 68-69 % at all slaughter weights whereas fat percentage increased from 10.3 at 250 kg to 14.5 at 350 kg. Bone percentage was inversely related to fat percentage. The relative growth coefficients of muscle and fat were 1.28 and 1.80, whereas that of bone was 0.59. Sigrlificant changes in proportion of carcass parts and tissues were observed with increased slaughter weight. The propor-tion of hind decreased and that of back and belly increased, while chuck and shank remained relatively unchanged. Lean percentage was relatively unchanged by slaughter weight in all carcass parts except the chuck where it increased. The greatest increase in fat percentage was in the belly (7.6%) followed in decreasing order by the back (5.4%), shank (4.9%), hind (3.0%) and chuck (1.8%). The breeds did not differ in any of the traits except dressing percentage
