Abstract The purpose of this study was to evaluate carcass and non-carcass characteristics of local ducks. The research material was carcasses of five local male ducks aged 24 weeks (relative weight of about 1220 g) and five male Pekin ducks of 9 weeks of age (relative weight of about 1440 g) which were kept in the duck cage at the laboratory of Breeding and Genetics, Faculty of Animal Science, Hasanuddin University, Indonesia using intensive housing systems and commercial feed. The research method was all ducks were fasted and rested for 8 hours, slaughtered, carcasses, and parameters analyzed. Parameters measured were weight and percentage of carcass traits (wings, dorsal, thighs, breast, and neck), weight and percentage of non-carcass traits (head, shank, kidney, heart, trachea, esophagus, gizzard, liver, intestine, feathers), three types of weight (live weight, slaughter weight, and carcass weight), percentage of the total carcass, and meat bone ratio (thigh and breast). The results showed that there were no significant differences in all carcass and non-carcass parameters between local ducks and Pekin ducks except for non-carcass parameters, namely head, gizzard, shank, intestine, heart, and trachea. At different ages, Pekin ducks and local ducks showed similar carcass characteristics. These results show that the growth rate of Pekin ducks is faster than that of local ducks. These results become one of the bases and references that local ducks still need a breeding program for improving carcass growth to reach optimum carcass characteristics.

Progeny Performance

The effect of own performance traits of meat breed boars on fattening and carcass parameters of progeny in two different test stations (Bucany and Nitra) was evaluated. Own performance traits of boars were average daily gain (ADG) from birth to 100 kg live weight, backfat thickness (BF) and lean meat content (LMC) in field conditions. Progeny of boars was housed in pairs (gilt and barrow) and fed standardized feed mixture semi ad libitum. Progeny test lasted from 30 to 100 kg live weight. There were evaluated following parameters: ADG and feed consumption/kg gain (FC) at test from 30 to 100 kg live weight, slaughter weight (SW), proportion of meaty cuts (PMC) proportion of ham (PHAM), eye muscle area (EMA), and BF. At Bucany and Nitra was found the effect of genotype of boars on progeny BF and/or FC respectively. Better tested boars from own performance test individually as well as a group achieved in progeny better fattening and carcass traits than worse tested boars at Bucany (+33 g ADG, -0.21 cm BF, +2.34 % PMC). Progeny performance from better evaluated boars at Nitra did not exceed the progeny performance from worse tested boars. There was found significant effect of dams on progeny performance.

SummaryThirty Ossimi lambs were used in an experiment to compare those whose tail was docked shortly after birth with controls. After weaning at 4 months of age the groups were further subdivided and two of the four groups closely shorn according to a 2 × 2 factorial design.Male lambs at 20 kg were subjected to intensive finishing until the age of 50 weeks and nine were then slaughtered to determine carcass characteristics.There was a trend for increased live-weight gain in the docked lambs in the preweaning stage (up to 16 weeks).This trend was also present, although not statistically significant, in the final phase of intensive feeding from 20 kg weight to 50 weeks. Shearing significantly improved daily gain in this final period (P < 0·05). These increases in gain were also apparently associated with improvements in efficiency, as judged on a group basis.Docking and shearing also tended to cause increases in body measurements: height, chest girth and abdomen girth in the case of docking (P < 0·05) and chest girth, chest depth and abdomen girth in the case of shearing (P < 0–05).Carcass characteristics, measured on a relatively small sample, indicated several effects of docking and shearing on carcass traits although most of these were consistent with the expected differences stemming from the higher carcass weights acheived at 50 weeks of age by docked and sheared lambs.

AbstractSalbutamol (albuterol) is a β-adrenergic agonist marketed as a racemic (50: 50) mixture of R- and S-enantiomers (rac-salbutamol). Since only R-salbutamol is pharmacologically active and S-salbutamol has a longer half-life in humans, we examined R-salbutamol as a performance enhancer and repartitioning agent in domestic chickens. The effects of feeding diets containing R-salbutamol (5, 10 and 15 mg/kg diet) and rac-salbutamol (10 mg/kg diet) from day 21 to 42 post hatching on growth performance, carcass characteristics and tissue concentrations of R- and S-salbutamol in male and female broilers were compared with a control diet. R-salbutamol in the diet lowered the weight gains in both sexes, but the magnitude of reduction was greater in males as indicated by a significant R-salbutamol ✕ gender interaction. R-salbutamol also lowered food intake and improved food conversion ratios in both sexes. The relative weights of breast muscle and leg muscle were significantly increased and the relative weight of the fat pad was significantly decreased in birds of both sexes given diets containing R-salbutamol. Carcass protein content increased and carcass fat content decreased but the differences were not statistically significant. A significant dose-response effect was observed for tissue concentrations of R-salbutamol in all tissues, except the fat. Performance and carcass parameters in chickens given the 5 mg/kg R-salbutamol diet were similar to those given the 10 mg/kg rac-salbutamol diet, but tissue concentrations of R-salbutamol were lower. Chickens given the 10 mg/ kg rac-salbutamol diet had higher tissue concentrations of salbutamol than chickens given the 10 mg/kg R-salbutamol diet and higher concentrations of S-salbutamol than R-salbutamol in liver and leg muscle. Overall, these results demonstrate that R-salbutamol is an effective repartitioning agent in broiler chickens.

A study was conducted to determine the growth performance and carcass characteristics of indigenous Venda chickens fed a grower’s diet supplemented with varying levels of garlic meal. The study was based on four diets containing similar energy but different garlic meal supplementation levels of 0, 10, 15 and 25 g/kg DM. At 50 to 91 days, all the growth and carcass parameters measured were improved (P less than 0.05) by garlic meal supplementation. Feed intake, growth rate, feed conversion ratio, live weight, carcass weight, dressing percent, breast meat, thigh, drumstick, gizzard and fat pad weights of Venda chickens were optimized at different garlic meal supplementation levels of 14.7, 15.8, 8.0, 16.4, 14.2, 12.7, 11.2, 12.7, 8.2, 10.5 and 15.1, respectively. These findings have implications on ration formulation for indigenous Venda chickens. Thus, it was concluded that garlic meal supplementation improved feed intake, growth rate, live weight and carcass weight of Venda chickens.

Abstract. Estimates of phenotypic and genetic parameters for live Performance and detaiied dissection traits of body components and carcass tissues in Pekin ducks were calculated and used to construct selection indexes. The expected reduction in potential gain in live weight, dressing percentage and carcass characteristics resulting from restricting change in subcutaneous fat level to zero were assessed. The aggregate genotype measurements were weight at slaughter, dressing percentage and percent subcutaneous fat. The index measurements were weight at hatching, weight at slaughter, weight gain, breast width, breast length and breast circumference. The restricted indexes as compared with the unrestricted would lead to minimum reduction in potential gain of 29.4% in total net merit, 96.4% in weight at slaughter, 49.0% in dressing percentage, 74.0% in dissected side weight and 75.0% in muscle to bone ratio. The potential reduction in percent abdominal fat and percent bone in side was decreased by at least 38.5% and 80.2%, respectively. Absolute genetic response results showed that selecting for breast width alone (rTI = 0.79) would be recommended for birds with substandard levels of SCF, whereas use of the restricted index containing weight at hatching and breast width (rTI = 0.54) would be advised for individuals with Standard fatness.

This experiment was conducted to determine the effect of sex, Polydactylism and rearing system on carcass parameters of Fulani-ecotype chickens. Thirty chickens (15 males and 15 females) were randomly selected at 16 weeks old for carcass evaluation from population of the intensively (deep litter and cage system of management) kept Fulani eco-type chicken and were used for determining carcass characteristics such as Live weight, dressed weight, eviscerated weight, breast weight, Proventriculus weight, gizzard weight, liver weight, lung weight, spleen weight, bile weight, pancreas weight, heart weight, wing weight, shank weight, drumstick weight, thigh weight, head weight, neck weight, back weight. Data generated from the carcass parameters were subjected to least squares means using SAS 9.2 version 2008. Result showed that sex and polydactyly were significantly different (p<0.05) on all the carcass parameters measured except the organs. Birds kept in deep litter system had higher least squares means values than ones in cage system of management. This study revealed the effect of sex, polydactylism and rearing system on various carcass characteristics of Fulani ecotype chickens.

This study evaluated the performance, carcass characteristics, and centesimal composition of the meat of intact and castrated lambs of the Santa Inês breed and of the crossbred animals: one-half Santa Inês × one-half Texel. Thirty-four lambs were used, nine intact and nine castrated males of the Santa Inês breed, and seven intact and nine castrated crossbred males, all aged between 6 and 7 mo and with an average live weight of 18.2 kg. The design was completely randomized in a 2 × 2 factorial (two crossing and two sexual conditions), with statistical analyses performed in the STAT version 9.4 program. There was a significant difference the Santa Inês and the Texel and Santa Inês crossbred animals in feed conversion and average daily gain, with superiority of the latter group. Castration of animals aged <12 mo had no significant effect on the performance and on the carcass traits of the Texel and Santa Inês crossbred animals, whereas the genotype had a great influence on weight gain and on subjective and quantitative carcass characteristics, demonstrating that crosses in sheep are needed to explore the complementarity of breeds, and heterosis is needed to achieve better performances and carcass characteristics.

This research was conducted to study the effect of breed, Jaca Navarra (JN) vs. Burguete (BU), and finishing diet, conventional concentrate—diet 1 vs. silage and organic feed diet 2—on growth parameters and carcass characteristics from forty-six foals. Parameters as live weight (LW), average daily gain (ADG), body condition score (BCS), and fat depots were monitoring. In addition, the carcass parameters assessed were: carcass weight (CW), conformation, degree of fatness, morphology, and pH. Moreover, hindquarters of the left-half carcasses were sectioned in the main commercial primal cuts of leg. Results showed a clear “breed effect” in favor of BU foals, recording the highest productive values and carcass traits compared with JN foals. On the other hand, finishing diet contributed to improving the productive and carcass features of JN foals. In particular, diet 1 showed to affect positively the features analyzed compared with diet 2. Nevertheless, the meat primal cuts resulted in being unaffected by the breed and diet effects (except for knuckle), obtaining similar values among the groups of animals.

A study was carried out to evaluate growth performance and carcass characteristics of broiler birds fed with varying level of choline inclusion in their diets; T1 (control), T2 (10g/10kg) and T3 (20g/10kg). A total of 225 marshall broiler chicks were randomly divided into three (3) treatment group of 75 birds each. Each group was divided into five (5) replicates of fifteen (15) birds each laid in a completely randomized design. Feed and water was supplied ad-libitum and the experiment lasted for 49 days. The total feed intake (1316.75-14442.18) (24437.13-31999.76) for starter and finisher respectively, body weight gain (6227.30-8241.20) (10956.64-14182.96) for starter and finisher respectively, feed conversion ratio (1.73-2.26) (2.21-2.48) for starter and finisher respectively. Many (thigh, wings, back) of the carcass parameters measured were not significantly (p>0.05) affected by the treatments but significant difference (p<0.05) was observed in drum stick, breast and neck.  However, significant difference (p<0.05) was also observed in gizzard, liver and bile, heart, lungs, legs and head. There was significant difference (p<0.05) in primal cuts per live weight, primal cuts per dressed weight, organs per live weight and organs per dressed weight. In view of the results obtained, it can be concluded that treatment two (10g/10kg) performed better in terms of total body weight (TBW) and feed conversion ratio (FCR). Also in the carcass characteristics, treatment two performed better in terms of breast yield, drumstick, percentage of primal cuts from live weight (P/LW) and percentage of primal cuts from dressed weight.

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.
