Twenty-four 6-wk-old pigs were housed in individual metabolism cages and exposed for 6 wk to either 2 C or 20 C with ad libitum feed and water. The pigs at 20 C and 2 C had an average daily gain (ADG) of 544 g and 343 g (P < 0.01), respectively. Feed consumption was similar for both treatments, with feed:gain ratios being significantly lower in the 20 C group during the 1st and 3rd 2-wk periods. Spleen and kidney weights were a larger percent of ingesta-free body weight in pigs housed at 2 C. The percent body weight of livers, thyroids, testicles, seminal vesicles and bulbo-urethral glands were not statistically different between 20 C and 2 C housed pigs. Body protein and ash were 5 and 1.3% lower in the 2 C pigs. Differences in plasma ACTH between treatments within day were significant. Consistently lower levels of plasma ACTH were obtained from pigs housed at 2 C.

Abstract. slaughter traits. The experiment was conducted on 120 New Zealand White (NZW) and Californian (CAL) medium-sized rabbits and their F1 reciprocal crosses (CAL × NZW and NZW × CAL). The rabbits were fed pellets ad libitum, and slaughtered at body weight around 2.5 kg. The following traits were recorded: body weight and average daily gain at birth to slaughter, average feed consumption from weaning to slaughter, slaughter age, carcass weight, meat, bone and fat content of carcass, prime cuts weight (fore part, loin and hind part), and dressing percentage. The results indicated that reciprocal crossbred CAL × NZW and NZW × CAL rabbits were heavier than purebred animals. NZW × CAL crosses attained the slaughter body weight earlier, and had lower feed consumption. The dressing percentage in NZW × CAL crosses was highest, while the lowest in NZW rabbits. For other slaughter traits, except the fat content of carcass, effects of crossing rabbits were small. The magnitude of the crossbreeding effects depended on the direction of crossbreeding. Maximum effects in crosses for slaughter age, body weight, feed consumption and dressing percentage were obtained when the Californian breed was used as a maternal component.

The effects of four stocking rates (0.070, 0.093, 0.116 and 0.140m2/ bird) on the performance of two hybrids of commercial broilers were investigated. There were significant hybrid effects on initial and final body weights (P< 0.01) and on feed effici­ency (P <0.05) but not on average daily gain and feed consumption and mortality. Stocking effects which were not signi­ficant for initial body weight, feed efficiency and mortality were highly significant for final body weight, average daily gain and feed consumption, (P < 0.01). There were significant interactions bet­ween hybrid and stocking rate for average daily gain (P <0.01) and mortality (P < 0.05). It is suggested that in the humid tropics, the stocking rates of 0.116 and 0.140m2/ bird would be appropriate for rearing broilers. The results of the study also show­ed that different hybrids do vary on space requirements in respect • of certain produc­tion traits.

Abstract Hulless varieties of barley have been developed to improve the digestibility of this small grain. The objective of this project was to determine the feeding value of hulless barley relative to corn in a beef-finishing ration. Angus-cross steers (n = 12) were fed rations that included varying ratios of cracked corn and cracked hulless barley. Steers were stratified by body weight (BW) and allotted to one of four rations: corn, 2:1 ratio of corn to barley, 1:2 ratio of corn to barley, and barley. All treatments included concentrate at 85% and baleage at 15% of total ration dry matter (DM). Rations were fed ad libitum on an individual basis using Calan gates. Feed refusals were measured daily. Steers were weighed and ultrasound 12th rib fat thickness (FT) was measured every 28 d. Steers were harvested at a commercial abattoir when average FT exceeded 0.9 cm. Average daily gain (1.2 kg/d), final BW (653 kg), feed to gain efficiency (10.2:1), and final ultrasound FT (0.94 cm) were not different (P ≥ 0.1486) between treatments. Steer DM intake was lower (P ≤ 0.0496) for those fed corn (9.8 kg/d) compared to those fed barley (12.2 kg/d) or a 1:2 ratio of corn to barley (11.7 kg/d); steer DM intake was similar (P ≥ 0.0640) for those fed a 2:1 ratio of corn to barley compared to those fed the other rations. Finishing ration did not affect hot carcass weight (384 kg; P = 0.7158), carcass FT (1.6 cm; P = 0.9511), ribeye area (87.7 cm^2; P = 0.7184), kidney, pelvic, and heart fat (2.6%; P = 0.3842), and yield grade (3.5; P= 0.8802). Feeding hulless barley compared to corn resulted in similar performance and carcass characteristics when included in beef finishing rations although feed intake was greater when barley exceeded 56% of the ration DM.

SummaryThe effects of two levels of energy intake, ad libitum and 80% of ad libitum, of diethylstilboestrol implantation and no such treatment, and of two slaughter weights (‘450’ and ‘490’ kg), on the performance of Israeli-Friesian intact male cattle were studied.Average daily gain was 1130 g and 959 g and daily carcass gain was 630 g and 553 g for animals on ad libitum and 80% of ad libitum energy intake, respectively. Average daily gain was 1038 g and 944 g and daily carcass gain was 595 g and 562 g, for diethylstilboestrol-treated and untreated animals, respectively. Slaughter weight had little effect on rate of gain.The differences in conversion ratio of ME into live weight between treatments were small. Diethylstilboestrol-treated animals were slightly more efficient.The non-implanted animals on the restricted plane of nutrition and which had been slaughtered at ‘490’ kg had a significantly higher dressing percentage, a higher percentage of fat trim and less bone than animals slaughtered at ‘450’ kg body weight on both levels of nutrition.Among the diethylstilboestrol-implanted male calves, however, the animals fed at 80% of ad libitum feed and killed at ‘450’ or ‘490’ kg live weight had significantly more fat trim in the carcass and less bone than the animals fed ad libitum.

Weaned Friesian steers of 130 kg liveweight were offered a range of supplements from January until May while grazing hay aftermath at 5 steers ha-1. Some of the feeds were also given to similar steers in feedlots. The supplements comprised all combinations of oaten grain, linseed meal and pasture hay. Oats and hay were fed separately and ad libitum and the linseed meal was provided as a daily ration alone or mixed with oats. Above average rains fell in December and January but February and March were dry. The pasture supported an average daily gain of 0.55 kg day-1 during the first five weeks when still green but gains declined and responses to the supplements increased after the pastures dried off and especially after the first autumn rains. For steers grazed on pasture, average daily gains (kg day-1) during the 16 weeks of the experiment were: unsupplemented 0.24, supplemented with linseed meal 0.31, hay 0.43, linseed meal and hay 0.63, oats 0.60, oats and hay 0.73, oats and linseed meal 0.97, oats linseed meal and hay 1.01. For steers in feedlot, gains were : oats 0.12, hay 0.33, oats and hay 0.41, oats linseed meal and hay 0.82. The feed consumption of the steers in the feedlot increased with the protein content of the ration and their liveweight gain was closely related to the amount of food consumed.

Fifty-two litters involving 380 pigs from Duroc (D), Landrace (L) and D × L breed groups were used in one experiment and 12 rats in another to assess the nutritive value of broken rice and corn as energy sources in starting diets of pigs from 3 to 10 wk of age and in diets of rats from 21 to 49 days of age. Dietary treatments in the pig experiment consisted of either broken rice, corn, or a broken rice/corn mixture (1:1) as the major ingredients or a control diet based on corn and soybean meal with 20% dried skim milk. Similar diets based on broken rice, corn or the mixture were used in the rat experiment. No significant differences were found during the pre-weaning period, but postweaning body weight at 8 and 10 wk of age, feed consumption and rate of gain were significantly (P < 0.05) greater for pigs fed the control diet. Rate of gain was significantly (P < 0.05) less and feed:gain ratios were significantly (P < 0.05) greater for broken rice than other diets in the pig experiment. Digestibility of energy was greater for broken rice than for other diets but digestibility of nitrogen was low for all diets. Lower feed intake and daily gain of pigs from Duroc and crossbred gilt breed groups was noted compared with pigs from Landrace or crossbred sow groups. No significant differences between dietary treatments were noted in the rat experiment. Digestible energy was estimated for all diets at 3,300–3,400 kcal/kg for pigs and 3,500–3,550 kcal/kg for rats.
