Meat Production from Wild Kangaroo: The Species, Industry, Carcass Characteristics and Meat Quality Traits

The effects of feeding concentrates with alternative ingredients to cereal and soybean meal on growth performance, carcass characteristics and meat quality traits of feedlot lambs were studied. A total of 105 non-castrated male lambs were randomly assigned to one of three treatments (5 replicates per treatment): Control (CON, similar to commercial concentrates), Camelina (CAM, where camelina meal replaced 50% of the crude protein from the soybean meal in the CON concentrate), and Fibrous (FIB, concentrate without cereals and soybean meal, with camelina meal in addition to several by-products, and 20% less energy). The CAM treatment performed as well as the CON one. The FIB treatment increased feed conversion rate and tended to improve the redness and the oxidative stability. The CAM and FIB were economically more favourable. We found that a concentrate for feedlot lambs based on alternative ingredients, including several by-products, could be a feasible alternative to typical cereal-soybean meal-based concentrates.

Meat Quality Traits

Castration in beef cattle production has been proposed to reduce sexual and aggressive behaviour, increase carcass fat deposition, and improve meat quality traits, such as tenderness and juiciness. The aim of the present study was to evaluate the effects of the age of castration on performance, subprimal yield and meat quality of Nellore cattle raised on a pasture system. A total of 24 Nellore males were raised in a grass-fed system with Brachiaria brizantha since birth until slaughter (at 30 months old). Three treatments were assigned: castration at weaning (CW); castration at 20 months old (C20); and intact bulls (NoC). Males were weighed, and muscle and fat thickness were periodically evaluated by ultrasonography. The cold carcass weight, dressing and carcass pH (pH 24), and subprimal cut weights were recorded after 24 h of chilling. Samples of Longissimus lumborum (LL) were taken to measure meat quality traits. Animals that were castrated at weaning had lower bodyweight after 10 months of age with no changes in the supplement intakes, average daily gain, hot carcass weight and cold carcass weight compared with NoC. Intact males had greater cooking losses and carcass yield compared with others, with no differences for LL pH 24 according to the treatments. The castration did not change the LL muscle area, but decreased total forequarter, chunk, shoulder and eye of round weights, and increased the back fat over LL and rump fat. Animals castrated at weaning had higher marbling compared with others. In addition, regardless of age, castration improved tenderness, increased LL total lipids and decreased moisture compared with NoC. For sensory property, steers castrated at 20 months of age had lower juiciness, and NoC had a greater global sensory property compared with steers castrated at 20 months old. In conclusion, steers castrated at weaning had lower growth rate, final bodyweight and meat production compared with intact males. However, when castration was performed at 20 months, animals did not differ in most cases from castration at weaning and NoC. Tenderness was improved by castration, but sensory traits did not differ between groups.

Vitamin E Supplementation

Abstract. The objective of this study was to evaluate the effects of dietary vitamin E supplementation on performance, slaughter-carcass characteristics and meat quality traits of Karya male lambs. Lambs weaned approximately at 10 weeks of age were divided into two groups. After the 10 days adaptation period, control group (CG, n7) and vitamin E group (VEG, n=6) lambs were fed on with concentrates ad libitum and 100 g hay/lamb/day for 70 days. In addition the VEG received a supplement on concentrates of 45 mg/lamb/day vitamin E during the fattening period. The meat quality traits were determined using m. longissimus dorsi (LD) obtained from split between 12th and 13th ribs on both groups lambs. Daily gain and feed conversion efficiency were 259 g and 5.3 for CG and 266 g and 4.7 for VEG, respectively. There was no vitamin E supplementation effect on the average daily weight gain and feed conversion efficiency (P>0.05). However, VEG had 10.5 % higher feed conversion efficiency than control lambs. Slaughter and carcass characteristics of lambs were not significantly affected from vitamin E supplementation (P>0.05). There were no effects of vitamin E supplementation on lightness (L*), redness (a*), yellowness (b*) and pH during 12-day aerobic storage. Thiobarbituric acid reactive substances (TBARS) values at day 2 were not affected by the vitamin E treatment. However, TBARS values on day 4 and 8 (P<0.05), and day 12 (P<0.01) were higher in the CG than in the VEG. Although not significant, 10 % higher feed conversion efficiency in VEG animals might suggest that vitamin E supplementation is useful to improve fattening performance.

High meat quality and specifically meat tenderness are desired traits by the consumers, however the environmental impact of meat production is becoming a relevant factor in the industry. Therefore, breeding of dual purpose cattle breeds may answer the high demand of meat production in the future. In this study we identified statistical differences between genotypes of CAST and CAPN1 gene variants with meat quality traits in a dairy breed (Nordic Red Cattle) and compared the results with beef breed (Aberdeen Angus). Our results show that the favorable alleles have not been selected in the studied dairy breed and thus could be used as a tool for improvement of meat quality. The genes were associated with specific meat quality traits (i.e. sensory juiciness, marbling score and meat color) also in the dairy breed. This supports the utility of known meat quality associated genetic variants to improve meat quality in dairy breeds.

Meat Quality Traits

Abstract: The objective of this work was to estimate genetic parameters for bird carcass and meat quality traits, as well as to explore the genetic patterns of the breeding values of this population using cluster analyses. Data from 1,846 birds were used to estimate the genetic parameters of production and quality traits using the multiple-trait animal model, and cluster analyses were performed. The heritability estimates ranged from 0.08± 0.03 for meat pH measured 24 hours after slaughter to 0.85± 0.09 for body weight. The genetic correlations between production traits were high and positive. The genetic correlations between meat quality traits were low and were not informative due to the high standard errors (same magnitudes as those of the genetic correlations). The genetic correlations between meat production and quality traits were negative, except between production traits and meat lightness intensity. Based on breeding values (EBVs), the evaluated population can be divided into four groups through cluster analyses, and one group is suitable for selection because the birds presented EBVs above and around the average of the population, respectively, for production and quality traits. Therefore, it is possible to obtain genetic gains for production-related traits without decreasing meat quality.
