Abstract Equations for estimating commercial meat cuts of water buffaloes finished in feedlot (means of initial body weight and age of 314 ±117 kg and 13 ±1.2 months, respectively) using biometric measurements performed in vivo, carcass traits performed postmortem, and the set of both measurements were determined. Seventy-five non-castrated males (25 of each genetic group: Jafarabadi, Mediterranean and Murrah) were used and allocated in collective pens to receive feeding and water ad libitum for 240 days. Body weight (BW), hip height (HH), and ultrasound assessments (backfat thickness – BFT; Ribeye area – REA) were performed and tested as independent variables. After the slaughter, the non-carcass components of each animal were weighed to obtain the empty body weight (EBW). Hot carcass weight (HCW), cold carcass weight (CCW), carcass length (CL, cm), carcass depth (CD, cm), and carcass compactness index (CCI, kg/cm) were obtained and tested as independent variables. The meat cuts (Brisket, Flank plate, Rump, Rump cap, Striploin, and Tenderloin) were obtained from right half-carcass and weighed. The equations were determined using the stepwise regression method and Mallows’ Cp criterion, and processed by the REG procedure in SAS. The independent variables which were included differed among the meat cut equations which can use both independent variables obtained in vivo and postmortem, or only those obtained postmortem: Brisket, kg = 0.165-0.004×EBW+0.007×HCW+0.017×CCW (R2 =0.81, SE =0.27, Cp=1.81); Flank plate, kg = -2.643-0.013×HCW+0.028×CCI +2.681×CL-1,021×HH (R2 =0.68, SE =0.116, Cp=2.73); Rump, kg = -4.975-0.004×EBW-0.004×HCW+0.032×CCI+4.771×CL-1.662×CD-0.017×BFT (R2 =0.84, SE =0.18, Cp=6.17); Rump Cap, kg = -0.485-0.002×EBW+0.011×CCI -1.291×CL (R2 =0.78, SE =0.19, Cp=2.20); Striploin, kg = -0.088-0.004×EBW+0.020×HCW +0.019×CCI-2.949×CL (R2 =0.85, SE =0.35, Cp=3.97); Tenderloin, kg = -2.125 + 0.008×CCI +1.863×CL-1.697×CD+0.698×HH-0.014×BFT (R2 =0.84, SE =0.12, Cp=5.89). In conclusion, the equations for estimating commercial meat cuts present good prediction and can be used for different GG of water buffaloes. Supported by FAPESP (#2014/05473-7).

Abstract This study determined equations to estimate the physical components of the buffalo carcass using biometric measurements performed in vivo, carcass traits performed postmortem, and the set of both measurements. Seventy-five non-castrated males (25 of each genetic group: Jafarabadi, Mediterranean and Murrah), with means of initial body weight and age of 314 ±117 kg and 390 ±58 days, respectively, were used. The animals were allocated in collective pens and received feeding ad libitum for 240 days. Ultrasound assessments [(backfat thickness (BFT); Ribeye area (REA)], weight, hip height (HH) measurements, and body condition score were performed every 28 days, and tested as independent variables. The postmortem measurements tested as independent variables were carcass length (CL, cm), carcass depth (CD, cm), cold carcass weight (CCW), hot carcass weight (HCW), and carcass compactness index (CCI, kg/cm). The empty body weight (EBW) was also obtained and subsequently used in the equations. The percentage of tissues which comprise the carcass was determined by the physical separation. The equations to estimate the physical composition of the carcass were developed using the stepwise regression method and Mallows’ Cp criterion, and processed by the REG procedure in SAS. The best prediction equations were those which used both independent variables obtained in vivo and postmortem, namely: Muscle, kg = 16.17 - 0,042×EBW + 0.211×CCW + 49.309×CD + 0.210×HCW - 35.570×HH (R² =0.91; RMSE =3.448; Cp =4.864); Fat, kg = 29.471 + 0.07×EBW - 33.716×CL + 0.285×BFT – 11.080×CD (R² =0.77; RMSE =2.151; Cp =2.568); Bone, kg = -34.261 + 20.380×CL + 18.356×HH + 0.011×EBW (R² =0.87; RMSE =1.181; Cp =2.218). In conclusion, the equations obtained from models with both in vivo and postmortem measurements present high prediction and can be used efficiently in the estimate of the physical components of the water buffalo carcass.

The experiment was performed on 60 French lop rabbits raised under extensive conditions and sacrificed at body weight of about 3 kg. It was found that the best indicators of meat weight (g) in rabbit carcasses were body weight, head width and lower thigh length among the traits measured in vivo, and carcass weight, chest girth and thigh circumference among the traits measured post mortem. In vivo prediction of saddle meatiness may be based on body weight, trunk length and thigh length, whereas post-slaughter estimation – on carcass weight, hip circumference and thigh circumference. Total meat weight in the hind half of the carcass may be predicted in vivo on the basis of body weight, head width and lower thigh length, and post mortem – on the basis of carcass weight, chest girth, hip circumference, thigh circumference and pelvic width. Multiple regression equations for meat weight estimation in the whole carcass and its middle and hind part were derived in the study. These equations may be applied in selection work directed towards an improvement in carcass meatiness. They may also be used to evaluate the results of experiments conducted on French lops.

AbstractA total of 1180 1-day-old Japanese quail (Coturnix japonica) chicks were used to investigate the effect of feathering rates on growth and slaughter traits. Feathering rates were classified based on the results of stepwise regression using numbers and lengths of both primaries and secondaries and tail length at 7 and 10 days of age as predictors. At 7 and 10 days old, number of primary feathers had phenotypically positive low correlations (rps) with body weight (BW), whereas number of secondaries had positive medium rps with BW at different ages. Lengths of primary, secondary and tail feathers had highly positive rps with BW traits at different ages. Results of stepwise multiple regressions indicated that BW at 14, 21 and 28 days of age can be predicted using lengths of secondary and tail feathers at 10 days old, number of secondaries at 7 days old and length of secondaries at 7 days old, respectively. Body weight at 35 days of age can be predicted using number of primaries,lengths of secondaries and tail at 10 days of age and number of secondaries at 7 days of age. Higher BWs were obtained in the fast-feathering class from 21 up to 35 days of age than in other groups, whereas the slow-feathering class had the lowest BW. Significant class differences were found for carcass weight, feather weight and dressing% favouring the fast- over the slow-feathering class. Therefore, early feathering rates improved BW at later ages and slaughter traits in Japanese quail.

Aim: The aim of the study was to determine the carcass and meat characteristics of male Kacang goat fattened by complete silage made from natural grass, Sorghum bicolor (L.) Moench and Pennisetum purpuphoides. Materials and Methods: This study examined 12 young male Kacang goats aged 10-12 months with an initial body weight of 10-12 kg. The livestock was divided into three groups randomly to receive feed treatments. The three treatments of this study included T1: Complete silage made from natural grass; T2: Complete silage made from S. bicolor (L.) Moench, and T3: Complete silage made from P. purpuphoides. Data were analyzed according to the analysis of variance procedure. Results: The carcass percentage of livestock T2 and T3 treatment was relatively similar but higher (p<0.05) than the T1 group. The non-carcass percentage of T2 and T3 was relatively the same but lower than T1. The water content of T1 treatment was higher (p<0.05) than T3, but relatively the same as T2 treatment. The collagen content of T2 and T3 was relatively the same but lower (p<0.05) than T1; likewise, the cholesterol of T2 and T3 treatments was relatively similar but higher than T1 treatment. The variables of slaughter and carcass weight, and non-carcass weight, meat protein content, acidity, cooking losses, water holding capacity, and tenderness were not significantly different between groups of animals. Conclusion: The use of S. bicolor (L.) Moench and P. purpuphoides as a basic forage in making complete silage has been shown to increase carcass percentage, the content (%) of fat, collagen, and cholesterol. Otherwise, the treatments have no effect on the content of pH, tenderness (kg/cm2), cooking loss (%), and water holding capacity (%) of male Kacang goat fattened. Therefore, S. bicolor (L.) Moench and P. purpuphoides plants have great potential to be developed by farmers/ ranchers as feed for goats.

The aim of this study was to evaluate the in vivo quantitative traits of carcass and commercial cuts of lambs fed diets containing 0, 12.5, and 25.0% mulberry hay replacing the concentrate. Twentyfour Ile de France lambs at approximately 60 days of age, with 15 kg body weight, were confined in individual stalls and slaughtered at 32 kg. Increasing levels of mulberry hay in the diet resulted in a linear increase in chest depth (R2=0.84), leg muscularity index (R2=0.71), and muscle:bone ratio (R2=0.95); a linear decrease in leg compactness index (R2 =0.75), shoulder weight (R2=0.78), and femur weight (R2=0.99) and length (R2=0.86); and a quadratic response from chilling losses (R2=1.0) and percentage of intermuscular fat. Mulberry hay can be used in the feeding of feedlot lambs without compromising their carcass quantitative characteristics.

Castor bean hulls (CBH), co-products of castor oil extraction, are high in dry matter (DM) and fiber and are emerging as alternative roughage in sheep feed. This could reduce feed costs since other sources of roughage can be more expensive. The effects of replacing Tifton 85 hay with CBH at 0, 33, 66 and 100% in the diet of sheep on the carcass characteristics, weights and yields of retail cuts and carcass measurements were studied. Twenty-eight non-castrated sheep averaging 7 ± 1.4 months of age with an initial weight of 19.5 ± 4.3 kg were slaughtered after 70 days of confinement. There was a linear decline (P ≤ 0.05) in slaughter body weight, empty body weight, hot and cold carcass weight and longissimus muscle area (LMA) as the percentage of dietary CBH increased. A linear decrease (P≤0.05) of the weights of all retail cuts and a quadratic effect (minimum yield of 9.84% with the replacement of 56.9%) of the neck yield were also detected as the percentage of CBH increased. No treatment effects (P > 0.05) on the yield of the other cuts were observed, but there was a linear decline (P ≤ 0.05) in the perimeters of the thorax, leg and rump and the carcass compactness index. Replacing Tifton 85 hay with CBH in sheep diets is not recommended because it decreases the slaughter body weight, cold and hot carcass weight, retail cut weights and morphometric measurements.

Abstract. This study examined the effects of cottonseed processing form and the inclusion of calcium lignosulfonate in high-concentrate diets for feedlot cull ewes on carcass traits and non-carcass components. Thirty Santa Inês cull ewes with an average body weight of 44.2 ± 5.2 kg and an average age of 50 months were distributed into collective stalls in a completely randomized design. The treatments consisted of diets including whole cottonseed, crushed cottonseed, whole cottonseed treated with lignosulfonate (100 g/kg, as fed), crushed cottonseed treated with lignosulfonate (100 g/kg, as fed), and a control diet without cottonseed. The experimental diets did not influence (P>0.05) average daily weight gain (0.195 kg/day), slaughter weight (51.74 kg), or in vivo biometric and on-carcass measurements. There was no difference (P>0.05) in loin-eye area or subcutaneous fat thickness as evaluated in vivo by ultrasound. There was no diet effect on hot carcass weight and yield (24.8 kg and 47.8 %), cold carcass weight and yield (24.2 kg and 46.8 %), or chilling loss (2.1 %). Non-carcass components did not differ in response to the diets (P>0.05). Dietary inclusion of calcium lignosulfonate increases the proportions of udder and liver relative to empty body weight (P<0.05). Neither the cottonseed processing method nor the inclusion of calcium lignosulfonate in high-concentrate diets for cull ewes affects their performance, biometric or morphometric measurements, non-carcass components, or qualitative traits of their carcass.

Annatto byproduct is the residue from the extraction of powder dye that covers the seed pericarp; after processing, between 94% and 98% of the original product is considered a byproduct. The aim was to evaluate the influence of increasing levels of annatto byproduct on the components of sheep body weight. Thirty-two male sheep, not castrated, with initial weight of 23.17 ± 1.45 kg, without a defined breed, were used in randomized blocks in all four treatments (0, 100, 200 and 300 g kg?1 of annatto byproduct in the diet dry matter). The increase to 300 g kg?1 of annatto byproduct had a negative linear effect (P < 0.05) for hot carcass weight (kg) and cold carcass weight (kg). Increasing levels of annatto byproduct resulted in a linear reduction (P < 0.05) for palette weight (kg), leg weight (kg), carcass compactness index (kg cm?1), liver weight (kg) and skin weight (kg). The inclusion of annatto byproduct up to 200 g kg?1 of dry matter in sheep diets did not affect the components of sheep body weight.

In vivo and carcass measurements were evaluated to predict carcass physical and chemical composition and to list the measurements that best fit the prediction of the composition of growing Santa Inês sheep carcasses. Thirty-three animals were used to measure the loin eye area by ultrasound in vivo (LEAu) and in the carcass. We used 39 animals for biometric measurement in vivo and 42 sheep for morphometric measurement in the carcass. For the physical and chemical compositions of carcasses, dissection of the half left carcass was carried out in 42 animals. The data were submitted to Pearson’s correlation analysis and t test. Simple and multiple linear regressions were performed using a stepwise procedure. All correlations between in vivo measurements and the physical and chemical compositions of carcasses (in kg) were significant, except for LEAu. Biometric measurements and hot (HCW) and cold (CCW) carcass weights were considered as predictors of the carcasses’ physical and chemical compositions. Slaughter body weight (SBW) was the variable that most influenced the equations in the assessment of in vivo measurements and HCW and CCW most influenced the equations for measurements on carcasses. Biometric measurements of Santa Inês sheep can be used together with the SBW to estimate the physical and chemical compositions of carcasses, with emphasis on body compactness index, breast width, wither height, and croup height. The morphometric measurements can be used together with carcass weight to estimate the physical and chemical compositions of carcasses, with emphasis on croup width, carcass compactness index, croup perimeter, external and internal carcass lengths, chest width, and leg length and perimeter. The HCW can be used to predict the physical and chemical composition of carcasses without affecting the accuracy of the prediction model.

SummarySeveral “in vitro” and “in vivo” studies indicate that heparin administration may affect platelet function. In this study we investigated the effects of prophylactic heparin on thromboxane (Tx)A2 biosynthesis “in vivo”, as assessed by the urinary excretion of major enzymatic metabolites 11-dehydro-TxB2 and 2,3-dinor-TxB2. Twenty-four patients who were candidates for cholecystectomy because of uncomplicated lithiasis were randomly assigned to receive placebo, unfractionated heparin, low molecular weight heparin or unfractionaed heparin plus 100 mg aspirin. Measurements of daily excretion of Tx metabolites were performed before and during the treatment. In the groups assigned to placebo and to low molecular weight heparin there was no statistically significant modification of Tx metabolite excretion while patients receiving unfractionated heparin had a significant increase of both metabolites (11-dehydro-TxB2: 3844 ± 1388 vs 2092 ±777, p <0.05; 2,3-dinor-TxB2: 2737 ± 808 vs 1535 ± 771 pg/mg creatinine, p <0.05). In patients randomized to receive low-dose aspirin plus unfractionated heparin the excretion of the two metabolites was largely suppressed thus suggesting that platelets are the primary source of enhanced thromboxane biosynthesis associated with heparin administration. These data indicate that unfractionated heparin causes platelet activation “in vivo” and suggest that the use of low molecular weight heparin may avoid this complication.
