Two trials involving a total of 120 Yorkshire SPF swine were conducted to evaluate the effect on live performance and carcass characteristics of replacing supplemental protein from 44% soybean meal (SM) with that from raw ground soybeans (RGS). Levels of 10.80, 16.45 and 22.15% RGS in the grower diets caused slower growth rates and reduced feed efficiency compared with those of pigs that did not receive RGS in their diets (P < 0.05). Although the results were not as consistent as in the grower phase, levels of 11.25 and 15.15% RGS in the finisher diets caused slower growth rate. Pelleting of a diet containing 3.65% RGS resulted in improved feed efficiency compared with that of the same diet unpelleted, when fed in the grower phase (P < 0.05). The area of the loin eye muscle tended to become smaller as the level of RGS in the diet increased. Treatment had no consistent effect on the other measures of carcass quality studied.

Effect On Growth

The effects of sex and age of castration of males on growth rate, feed efficiency and carcass characteristics in bacon type swine were measured using 16 pigs each as gilts, entire boars, and boars castrated at birth, 6, 12, 16, and 20 weeks of age. Castration at 20 weeks was too late since some pigs reached 200 pounds live weight before that age. Boars consumed less feed daily than barrows and gilts, were thinner in loin fat, and yielded a higher percentage of shoulder than gilts. The carcasses of boars and gilts were longer, had less fat covering over the shoulder and back, a larger area of loin, and a higher iodine number than those castrated late. Acceptability tests showed that sex or age of castration did not affect the flavour, odour, or tenderness of the meat.Purebred breeders can delay castration for better selection of boars without any serious effect on growth, physical carcass characteristics, and feed requirements. Although the market discriminates against boars, it appears questionable whether castration is necessary when boars are slaughtered at 200 pounds before they reach the age of 150 days.

Sorghum Grain

In three experiments, a total of 112 pigs were individually fed sorghum grain-soybean meal diets based on either high protein grain (10.9 to 13.3 per cent crude protein, air dry basis) or low protein grain (6.5 to 7.4 per cent crude protein, air dry basis). Soybean meal was incorporated in the diets at four levels-16.6, 13.8, 10.7, and 7.4 per cent. In experiment 1 the experimental diets were fed from weaning to 86 kg liveweight. In experiment 2 the experimental diets were supplied from weaning to 45 kg liveweight with a common standard diet being provided from 45 kg liveweight to slaughter, In experiment 3 a common standard diet was supplied from weaning to 45 kg liveweight. The experimental diets were commenced at this liveweight and continued until slaughter. Level of protein in the grain had no significant effect on growth rate or feed efficiency in any experiment, but in experiment 2 the mean eye muscle index of the pigs receiving the high protein sorghum diets was significantly greater than that of the pigs receiving the low protein sorghum diets. As level of soybean meal in the diet decreased, there was a general tendency for growth rate and feed efficiency to decrease. In experiment 1, growth rate and feed efficiency were lower in pigs receiving the 10.7 and 7.4 per cent soybean meal diets, but only prior to a liveweight of 45 kg. In experiment 2, each reduction in level of soybean meal resulted in a reduction in growth rate and feed efficiency prior to 45 kg liveweight. There was no difference between groups from 45 kg to slaughter, when all pigs received the same ration. In experiment 3, which commenced at 45 kg liveweight, growth rate and feed efficiency were reduced only when the level of soybean meal was lowered to 7.4 per cent.

Seventy-two Lacombe and 72 Yorkshire pigs were separately assigned, at 18-kg average liveweight, to three replicates, each consising of three pens containing eight male castrates, eight gilts or four of each sex. A 16% protein, barley-wheat-soybean meal, diet was fed ad libitum until the pen weight averaged 34 kg. Subsequently, the eight pigs were divided between two adjacent pens and received a 14.5% protein, barley-soybean meal, diet supplemented with 0 or 2.2 ppm bambermycins (Flavomycin) up to 90-kg market weight. Growth rate in the Lacombe population was faster (P < 0.01) in both the growing (730 g/day) and finishing (906 g/day) periods than in the Yorkshires (547 and 767 g/day, respectively). Daily feed intakes were higher (P < 0.01) for the Lacombes (1727 and 3174 vs. 1392 and 2659 g/day, respectively) but gain:feed ratios and carcass measurements were similar in both breeds. Differences between castrates and gilts, for performance and carcass data, were relatively greater in the Yorkshires and appeared to be a result of the breed differences in feed intake. Results from mixed-sex pens were within the range of values obtained from unisex pens. Inclusion of bambermycins did not affect (P > 0.05) live performance or carcass measurements of pigs in either population, perhaps because the experimental conditions allowed a level of growth, in unsupplemented pigs, superior to those typical of commercial production.

The influence of breed of sire on carcass traits was examined by studying data collected on 134 steers produced by mating Shorthorn cows with Shorthorn, Angus, Hereford, and Charolais bulls. The steers were fed out in two groups: one group was slaughtered at 18 to 23 months as they reached a live weight of 900–1000 lb and the other group at approximately 30 months of age. In each group the steers sired by Charolais bulls gained more rapidly, possessed more bone, produced heavier carcass weight, and showed largest eye muscle measurements. There were no appreciable differences among the crosses within the sire groups represented by the British breeds except that Hereford × Shorthorn surpassed Angus × Shorthorn and Shorthorn in growth rate significantly and for a slight superiority in marbling for the Angus compared with the Shorthorn.

Three trials were conducted involving a total of 44 barrows, individually self-fed pelleted corn-based diets in which dried brewers’ grains supplied 0, 25, 50, 75 or 100% of the supplemental protein. There were no differences (P > 0.05) between the average growth rate of pigs receiving a control diet based on corn and soybean meal and that of pigs receiving diets in which dried brewers’ grains supplied up to 50% of the supplemental protein. When dried brewers’ grains supplied more than 50% of the supplemental protein, growth rate and feed efficiency tended to decline.

The growth and carcass characteristics of first-cross Border Leicester x Merino ram, cryptorchid and wether lambs were compared over a range of slaughter weights (35-55 kg). Lambs were offered feed ad libitum after weaning. The growth rate of wether lambs (221 g/day) was less (P< 0.01) than that of rams and cryptorchids (308 and 280 g/day respectively, P = 0.076). The dressed carcasses of the wether lambs were approximately 2 percentage units heavier than those of the ram and cryptorchids, but this difference was partly due to the weight of the testes. Across all sex groups, dressing percentage increased by 0.46 percentage units per kg increase in carcass weight. The carcasses of rams and cryptorchid lambs tended to be leaner than those of wethers. Fat score distributions, based on export standards, were such that wethers scored higher (fatter) than rams and cryptorchids (P< 0.05). There was a significant sexx carcass weight interaction with GR tissue depths. Above 17 kg carcass weight, tissue depth of wether lambs was greater than those of the other sex types. Of 12 families assessing consumer acceptability (taste, smell, size, fatness and tenderness) of leg roasts, the majority showed no preference for any of the sexes.

Hereford, Charolais and Brahman sires were mated to Hereford, Shorthorn, Jersey and Friesian xshorthorn cows for four successive years from June 1969 at Struan Research Centre in South Australia. Assistance was given during 15 .9% of calvings resulting from Charolais sires, 6.8% resulting from Brahman sires and 2.1% from Hereford sires (differences statistically significant, P < 0 05). A greater percentage of Friesian x Shorthorn (13.8) than of Shorthorn (5.0) or Jersey (4 3) cows were assisted at birth (P< 0.05). There were no significant differences between the percentage of Hereford cows assisted (10.9) and that of any of the other dam breeds. There were no significant differences in calf mortality among sire breeds or among dam breeds. Charolais-sired calves were heavier at birth, 270,340 and 430 d old and had heavier (1 95 kg) carcasses with a smaller proportion of fat than Brahman- and Hereford-sired carcasses (180 and 167 kg respectively) at 430d old. Brahman-sired calves were heavier than Hereford-sired calves at birth, 370, 430 d old. However, they were significantly lighter at 270 d old. Hereford cows gave birth to significantly heavier calves than Shorthorn and Jersey cows but there were no clear differences due to dam breed in growth rates of calves, carcass weights or composition. It was concluded that the use of Charolais sires in the lower South East of South Australia can result in significant increases in the growth rate of slaughter cattle and in the production of leaner carcasses. Brahman sires did not exhibit clear advantages over Hereford sires. No definite conclusions could be drawn about the dam breeds examined in the study.

SUMMARYTwo experiments were carried out to compare the performance and carcass quality of pigs given diets based on barley, wheat or maize meal, and another two experiments comparing these cereals, flaked maize and sorghum. In general, differences in the utilization of feed for live-weight gain could be related to differences in the digestible energy content of the cereals used in the diet, although in some experiments pigs behaved atypically on individual diets. Flaked maize was consistently inferior to the other cereals in the efficiency of conversion of its digestible energy, possibly because of its poorer amino acid balance and its low levels of lysine and tryptophan in relation to energy. Differences between experiments in the performance of pigs fed on the various diets are also discussed. Differences between treatments in killing-out percentage and predicted lean percentage were small, and carcasses of pigs from all treatments were acceptable for bacon curing.

Red Tilapia

Abstract Red tilapia is kind of freshwater culture fish is quite popular because it has several advantages compared with other types of freshwater fish. To fullfil the demand of red tilapia can be overcome by cultivation. Effort to increase the production of red tilapia is to improve the quality of feed. The purpose of this study was to try the effect of the use of sword bean seed meal on the growth rate, survival rate and feed efficiency of red tilapia. The research method is experimental with completely randomized design (CRD) with five treatments and four replications. The treatments used were: (A) sword beans seed meal at 0% and soybean meal by 50%, (B) 10% sword beans seed meal and 40% soybean meal, (C) 20% sword beans seed meal and 30% soybean meal, (D) 30% sword beans seed meal and 20% soybean meal and (E) 40% sword beans seed meal and 10% soybean meal. The main parameters that measured were growth, survival rate and feed efficiency. Secondary parameters measured were water quality. Analysis of the data using analysis of variance (ANOVA) and to know the difference between treatments using Duncan's Multiple Range Test. Results showed the administration of sword bean seed meal on feed rations provide a significantly different effect (p<0.05) on the growth and feed efficiency but not significantly on survival rate of red tilapia (p>0.05 ). Highest daily growth rate obtained on treatment B on feed containing 10% of sword bean meal (1.20 %) was significantly different than treatment A (1.02 %), C (0.88 %) , D (0.85 %) and E (0.75 %) . Lowest daily growth rate was treatment E that significantly different with treatment A and B but not significantly different with treatments C and D. Highest feed efficiency obtained on treatment B (30.29 %) was not significantly different than treatment A (27.56 %), C (25.95 %) and D (27.78 %). Lowest feed efficiency was treatment E (17.84 %) significantly different than treatment B. Subtitution of sword bean seed meal in feed rations gave result that was not significantly different effect on the level of survival of red tilapia. Water quality of red tilapia rearing media was temperature range between 25-28° C, pH 7-8, dissolved oxygen 2-5 mg/L and ammonia 1.5 to 3.0 mg/L.
