Two experiments, involving 144 individually-fed pigs, were conducted to determine the effects of fish visceral flour in growing and finishing rations on the performance and carcass characteristics of bacon pigs.The most rapid average daily gains in this study were obtained from pigs fed mixtures of fish visceral flour and soybean meal. Pigs fed fish visceral flour as the only source of supplementary protein made slower gains in both experiments than those fed other rations.Pigs fed high energy rations made more rapid gains in the finishing period and more efficient gains in the finishing and total feeding periods than those fed the control rations.Level of fish visceral flour in the ration had no significant effect on carcass scores and grades. However, area of loin muscle decreased with increasing levels of fish visceral flour. High energy rations had an adverse effect on carcass measurements.

The study investigated the effects of re-alimenting dietary protein or energy on growth, carcass characteristics and meat eating quality parameters of sheep. Twenty-seven intact rams (~9 months; 11.3 ± 0.5 kg) were randomly divided into three groups. Each group was fed a maintenance diet (MT) containing, on dry matter (DM) basis, 105 g/kg crude protein (CP) and 8.4 MJ/kg DM metabolizable energy (ME) for 30 days. Thereafter, they were continually fed the same MT or re-alimented with a high protein diet (HP) containing 169 g/kg DM CP and 9.3 MJ/kg ME or a high energy diet (HE) containing 123 g/kg DM CP and 10.6 MJ/kg ME for an additional 30 days to determine the effects of re-alimentation of protein or energy on their growth performance and carcass characteristics. During the initial 30-day period, DM intake (DMI) and growth performance were similar among the three groups. However, upon re-alimentation, average daily gain (ADG) and feed efficiency of sheep re-alimented with HP were greater than those maintained continually on MT or re-alimented with HE. Sheep on HP had higher feed efficiency, ADG and heavier carcasses than those fed MT or re-alimented with HE during the whole 60-day period. Growth of most viscera was less responsive to the restriction-re-alimentation feeding regimen except for the weights of the lungs, heart and intestines. Meat from sheep re-alimented with HE had a more intense ‘sheepy’ flavour than those fed MT or re-alimented with HP, but juiciness and tenderness were not affected. The higher ADG of sheep re-alimented with protein may be related more to enhanced efficiency of feed utilization than to higher DMI.Keywords: average daily gain, feed restriction, nutrient utilization efficiency, visceral organs

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

Abstract This study evaluated the effect of different sources of nitrogen [soybean meal (SM); cottonseed meal (CM); cottonseed + urea (CU); and urea (U)] associated with spineless cactus on intake, digestibility, performance, carcass characteristics and meat quality of confined lambs. Forty male Santa Inês sheep, uncastrated, with initial body weight of 23.00 ± 1.66 kg were distributed in random blocks design and slaughtered after 58 days of confinement. Dry matter (DM) intake (1.16 ± 0.19 kg/day) did not differ (P > 0.05) between nitrogen sources, but the intake of crude protein (CP) and non-fibrous carbohydrates (NFC) was lower (P < 0.05) for sheep consuming CU. Sheep fed with diets containing U had lower digestibility of DM, CP and NFC (P < 0.05). The average daily gain (0.15 ± 0.04 kg/day) and the slaughter body weight (32.07 ± 2.86 kg) did not differ between nitrogen sources, but the cold carcass and loin weight was lower (P < 0.05) for sheep fed with U. The water retention capacity and meat protein content were greater (P < 0.05) for animals fed with SM. Soybean meal or cottonseed meal associated with spineless cactus-based diets for sheep meat production are recommended because it allows greater DM digestibilityand improves carcass characteristics and physicochemical composition of the meat.

The Relationship

Rations varying in energy (65 to 79 per cent TDN or 69 to 88 per cent apparent digestible energy) and protein (13 to 21 per cent) were studied in two experiments with 120 pigs of four strains. Rate of liveweight gain tended to be fastest in pigs fed high energy-high protein rations throughout. Males gained more rapidly than females, with strain differences being evident. Strain × sex interactions in rate of gain were present in both the growing and finishing period, with a ration × strain interaction present in the growing period. There was an indication that in the growing period pigs on high energy, particularly high energy-high protein rations ate more than pigs fed low energy rations. In the finishing period low energy rations were consumed at a higher rate than high energy rations with protein level having no influence on feed intake. In the growing period to 110 pounds, high protein rations resulted in improved feed efficiency as compared to medium protein rations, while in the finishing period to market weight high energy rations were more efficient than low energy rations. There was evidence that high protein alone or in combination with high energy rations also improved efficiency of feed utilization in the finishing period. Female pigs required less feed per pound gain than male pigs in the finishing period. High energy rations resulted in increased dressing percentage and generally inferior carcasses. There was an indication that high protein rations resulted in leaner carcasses. Carcass length was not influenced by ration. Carcasses from female pigs excelled those from male pigs in all factors measured except carcass length. Strain differences in carcass characteristics existed but no appreciable strain × ration interactions were noted.

Ingestive Behaviour

Context The water buffalo (Bubalus bubalis) is a valuable species in part because it is a multipurpose animal; its milk, horns and skin are all useful, and its meat is rich and nutritious. However, water buffalo meat still suffers many marketing restrictions. Aims The present study evaluated performance, ingestive behaviour, carcass characteristics and meat quality. Methods We examined the meat of 24 Murrah water buffaloes that weighed 287.8±1.8 kg and were divided into four groups that received 0, 250, 500 or 750 g/kg dry matter (DM) of a 3:2 blend of spineless cactus–cottonseed (henceforth, referred to as the blend) for 125 days in a completely randomised design. Key results The inclusion of the blend resulted in diets with increased moisture and crude protein intake at 250 g/kg inclusion and reduced intakes of non-fibrous carbohydrates and total digestible nutrients per kilogram DM, which led to an increased DM intake, but significantly lower (P&lt;0.001) final bodyweight, average daily gain, and hot carcass weight, thus resulting in a significantly lower (P&lt; 0.001) growth efficiency. Moreover, there was a reduction in the ammonia-nitrogen concentration and time spent drinking (P≤0.05). The ruminal pH and time spent feeding, chewing and defecating increased (P≤0.05), the fat content and colour parameters of the water buffalo meat increased, and the shear force decreased (P≤0.05) in response to the inclusion of the 3:2 blend of spineless cactus–cottonseed in the diet. The time spent on both rumination and urination, most of the physicochemical properties, and the consumer appeal of the meat, were not affected by the inclusion of the blend (P&gt;0.05). Conclusion The 3:2 blend of spineless cactus–cottonseed is not an effective replacement for corn bran and soybean meal in buffalo diets because, despite improving the rumen pH, the blend reduces the performance and carcass characteristics of the water buffalo. However, the fat content, coloration and softness of the meat improved, which is of commercial importance. Implications The inclusion of the spineless cactus–cottonseed blend in place of the high-concentrate diet did not affect the consumer appeal of the meat. The meat characteristics were scored as ‘like moderately’ (6–7 on a 9-point hedonic scale). On the basis of the scores of the panellists, all of the meats were well accepted.

Birds fed with vegetable diets rely on the endogenous synthesis of creatine, which requires amino acids, some of which, for example arginine (Arg), are considered essential for several physiological and metabolic functions. Creatine is limited to high energy expenditure cells, particularly muscle cells. The objective of this study was to evaluate the inclusion of guanidinoacetic acid and arginine (as precursors of creatine) in vegetable diets, on the performance, quality, and yield of broiler chickens. The treatments consisted of diets based on corn and soybean meal (T1); corn, soybean meal + 3% meat meal (T2); corn, soybean meal + 0.08% guanidinoacetic acid (T3); and corn, soybean meal + 0.08% L-arginine (T4). The productive performance of the birds aged 7-, 21-, and 42-days-old was determined. Eighteen 7-day-old birds were sacrificed per treatment to evaluate breast and leg yield, and breast muscle fibers, and eighteen 42-day-old birds were sampled per treatment to determine serum uric acid, urea, creatine, lactate, and glucose concentrations. The same birds were slaughtered to calculate carcass yield in relation to live weight and commercial cut yield. The right pectoralis major muscle of each bird was used to test pH, color (luminosity L*, red index a*, and yellow index b*), and loss of water by pressure analysis, and the left side was used to analyze losses by defrosting and cooking. The data were analyzed using the software SAS. Diets to which meat or vegetable meal plus guanidinoacetic acid or L-Arginine were added resulted in higher live weight and breast meat percentage at 7 days old. Feed conversion was affected for a total period of 1 to 42 days of age (P < 0.0002). The birds with a diet supplemented with vegetable and meat meal had better feed conversion when compared to the birds that were fed with other diets. Treatments did not affect carcass and commercial cut yields, percent loss by cooking, pressure and defrosting of the broiler breast meat, or color (L, a*, and b*) and pH values.
