The experiment was conducted to evaluate the effect of dried bloodrumen content mixture (DBRCM) on carcass characteristics of broiler chicks to replace soybean meal (SBM). A total of 225 unsexed day old broiler chicks (SASSO C44) were randomly distributed to five dietary treatment groups in a completely randomized design. Each treatment was replicated thrice with 15 birds per replicate. The experimental diets were formulated to contain 100%SBM+0%DBRCM (T1), 80%SBM+20% DBRCM (T2),60%SBM+ 40% DBRCM (T3), 40%SBM+60% DBRCM(T4) and 20%SBM+80% DBRCM (T5) in 56 days of age. At the end of the experiment, two male and two female birds per replicate were used to determine carcass characteristics. The result revealed that the edible carcass yield ranged from 977.9-1159.3g. The dressing percentage based on the edible carcass weight was 63.9 % (T1), 66.6 % (T2), 65.4 (T3), 64.2% (T4) and 63.1% (T5). There was no a significant difference (P>0.05) in both edible carcass yield and its dressing percentage. The commercial carcass weight was 937.4g (T1), 984.7g (T2), 962.0g (T3), 925.0g (T4) and 833.1g (T5) and the dressing percentage was 54.9%, 56.6%, 55.3%, 53.7% and 53.7% for T1, T2, T3, T4 and T5, respectively. Significant difference (P>0.05) was not observed in commercial carcass yield and its dressing percentage among the treatment groups. There was no a statistical marked difference (P>0.05) in total nonedible offal and edible offal. Females had more (P<0.05) breast meat than that of males. The abdominal fat and abdominal fat percentage were not significantly influenced (P>0.05) by a diet containing DBRCM. However, abdominal fat and its fat percentage were higher (P<0.05) in females than males. Based on this result, it could be concluded that DBRCM can replace soybean meal up to 80% substitution level without any adverse effect on carcass characteristics.

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.

EIGHT hundred Starbrow day-old broiler chicks were raised on deep litter on a commercial broiler starter ration. At the end of seven weeks the chicks were randomly and equally alloted to five experimental broiler finisher rations in which maize and gari constituted the main carbohydrate source in the proportions 58:0, 39:16, 29:24.5, 19:33 and 0.49% of ration, respectively. The protein source, groundnut cake, was varied accordingly such that the five rations were isonitrogenous and isocaloric. All other ingredients were mixed in the same amounts for all five rations which were balanced for essential nutrients. All chicks received ad libitum intake of feed and water from the eight week to the thirteenth week when the experiment was concluded. Feed consumption, growth rate, feed efficiency, dressed carcass percentage, liver Weight and abdominal fat percentage were used as parameters to evaluate the relative efficacy of the five ration treatments.  Birds on gari rations consumed 3.2% less feed on the average, than those on the Control maize ration, for nearly identical gains. Feed/gain ratio was, therefore, slightly lower for the gari treatments, the lowest value coming from the ration in which maize/gari ratio was 29%:24.5%. Average body weights, rate of gain and feed gain ratio were not significantly different. Variations in carcass and organoleptic measurements indicated no significant differences from dressed carcass percentage, liver weight percentage, tenderness, juiciness, colour or general acceptability. However, abdominal fat percentage was significantly [P<0.001] larger in the gari rations than the control maize ration. This value was highest in the ration that contained only gari as the major carbohydrate source. There was no significant difference in the iodine number of the abdominal fat of the five treatments.  The results of this study suggest that gari can replace all the maize in broiler finisher rations or constitute up to 49% of the whole ration, without any decrease in growth rate or carcass quality of broilers, provided such a ration is balanced for protein and amino acids. The best substitution level from this study appears to be at 50%, or 29% of the whole ration.

The residue originated from antibiotics and hormones had been thought to carry out adverse effects for the human who consume meat processed from the broilers treated by antibiotic feed additive. For this reason, using an alternative additive such as probiotic might produce healthier meat. The objective of the recent study was to evaluate administering different levels of probiotic yakult + tape yeast (YTy) into the mixing of rice bran + corn bran (RCB) to replace 30% of the commercial diet to carcass yield and abdominal fat of broilers. As many as 100 broiler chicks, Cobb strain, were reared up to 5 weeks in this study. The study was designed into a Completely Randomized Design with subsampling consisted of 5 treatments, 4 replications, and 2 sub samples. Broiler commercial diet with the market code of CP 511 Hi-provite manufactured by PT Charoen Pokphand was used for a positive control diet (P0+). The RCB feeds were mixed with 0, 10, 20, and 30 ml/kg of probiotic YTy then being used to replace 30% of the commercial diet to build experimental diets P0-, P1, P2, and P3, respectively. The results of the recent study indicated that administering 10‒30 ml/kg of probiotic YTy highly significantly (P<0.01) increased the weights of the whole carcass and carcass parts. The percentages of whole carcasses among P1, P2, and P3, however, were not statistically different. The percentage of the breast significantly (P<0.05) increased while the percentage of the back significantly (P<0.05) decreased. Although statistically not significant differences, the abdominal fat percentage tended to decline. In conclusion, administering a probiotic YTy in the diet increased the percentage of the whole carcass and tended to reduce the abdominal fat of the broiler.

Bulls of Charbray breeding and Hereford bulls were turned out with a commercial herd of Hereford cows in southwestern Saskatchewan in 1956. It was assumed the cows were bred at random. At weaning in 1957, 25 Charbray × Hereford (crossbred) steers and 25 Hereford steers were selected at random, weighed and removed to a commercial feed lot where they were fed in two groups to a desirable slaughter finish.Crossbred steers were heavier at weaning, gained more per day on feed and returned a higher hot carcass weight with a greater eye of lean area than Hereford steers. There was no significant difference between groups in dressing percentage, average thickness of rib fat, TDN consumption per pound of liveweight gain, or average muscle fibre diameters of samples taken from m. longissimus dorsi. The Hereford group produced a higher proportion of choice carcasses than the Charbray × Hereford group.

Eighteen non castrated Murrah male buffaloes, averaging 403 kg in weight, have been used in a feed lot randomized complete-block design, to test three different diets (T) with different combination of roughage (R) and concentrate (C). Tukey test has been used (5% of significance) to evaluate the obtained averages. The trial was carried on at AGRONOMIC INSTITUTE OF PARANÁ (Pinhais town, Paraná, Brazil), during 91 days. The animals have been fed twice daily, and the diets contained (%): T1 =75 R : 25 C; T2 =65 R : 35 C and T3 =55 R : 45 C, and it was calculated to have the same level of protein and energy in its composition, aiming to evaluate the diets effects on the animals’ performance on body weight and carcass characteristics. The R utilised was corn silage plus 0.5% of urea. The C was composed by soybean, wheat meal, corn, cottonseed, plus mineral, presenting: T1 =32.78 and 71.08; T2 =24.17 and 66.50; T3 =20.23 and 63.84, in percentage of crude protein and total digestive nutrients, respectively. The following quantitative characteristics have been evaluated: Hot Carcass Weight (HCW); Cold Carcass Weight (CCW); Hot Carcass Dressing Percentage (HCP); Cold Carcass Dressing Percentage (CCP); Loss After Cooling (LC); Carcass Length (CL); Leg Length (LL); Thigh Thickness (TT); Longissimus dorsi muscle area between 12th and 13th ribs (LA); Loin Area per 100kg of Cold Carcass (LA/100kg CC); Loin Fat Thickness Under the Skin, measured between the 12th and 13th ribs (LF); Bones Percentage (BP), Muscle (MP) and Fat (FP) of the Carcass - data, relative to 9th, 10th and 11th ribs. The evaluated qualitative characteristics were: Carcass Conformation (CONF); Meat Marbling (MM); Meat Texture (MT); Meat Color (MC). The diets have not affected (P > 0.05) the main carcass characteristics: HCW(kg)=265.83; 267.67 and 268.67; CCW(kg)=257.97; 260.92 and 259.27; HCP(%)=50.28; 51.20 and 51.05; CCP(%)=48.80; 48.81 and 49.45; LC(%)=2.96; 2.91 and 3.13; CL(cm)=133.75; 133.50 and 135.83; LL(cm)=70.66; 71.33 and 72.40; TT(cm)=26.16; 26.25 and 26.25; LA(cm2 )=65.48; 67.83 and 62.76; LA/100kg CC(cm2 )=25.37; 26.16 and 24.20; LF(mm)=7.58; 8.42 and 6.88, respectively for T1 , T2 , and T3 . Higher values (P < 0.05) of BP (%) have been observed in T3 (17.32) when compared with T1 (16.06). However, T2 (16.38) had a non-significant difference (P > 0.05). The MP (%) and FP (%) were similar (P > 0.05) for the three diets, and the values were: T1 =56.47 and 27.85; T2 =61.07 and 22.73; T3 =59.00 and 23.50, respectively. The diets have not affected (P > 0.05) the qualitative carcass characteristics, and the marbling observed has been classified as soft. It has been concluded that the use of different relations of roughage and concentrate for non-castrated male buffaloes, submitted to a confined system, on diets of the same protein and energy levels, at the trial conditions, have not influenced the productive performance of the animals, neither the carcass qualitative and quantitative characteristics.

The carcass yield of prescribed proportions of muscle and dissectible fat, described as 'carcass beef ', was studied in 49 steers of four breeds. Carcass beef consisting of 80% muscle, 20% fat and also of 75% muscle, 25% fat was predicted from fat thickness (FT), liveweight, carcass weight and dressing percentage. Carcass beef as a percentage of carcass weight was usefully estimated from FT (± 3%) but not from the other parameters. Carcass beef percentages and the corresponding FT measurements up to 15 mm were tabulated for the four breeds. There was no significant difference between the Herefords, Angus and Charolais X. Yield was less in the Friesians at a common FT, but a smaller FT was required to obtain a yield from carcasses of that breed. Carcass beef as a percentage of carcass weight, where the carcass beef composition is of specified proportions of muscle and dissectible fat, is proposed as a basis for the evaluation and marketing of carcasses.

The carcass characteristics of unsexed Obamarshal broiler chickens fed three levels (4, 8 and 12%) of Crude Fibre (CF) and three levels of Metabolisable Energy (ME) at 2600, 2800 and 3000 ME (Kcal/kg) in multi-fibre source-based diets were assessed using a 3x3 factorial design. The nine experimental diets, each for the starter and finisher phases maintained the calorie: protein ratios of 123:1 and 140:1 respectively. Two hundred and sixteen (216) dayold unsexed broiler chicks were allotted at the outset to nine dietary treatments at 24 per diet with 8 birds per replicate. There were 3 replicates per treatment arranged in a completely randomised design. Diets were formulated in accordance with the standard nutritional specifications for the broiler chickens. Feed and water were provided to the birds ad libitum for 8 weeks. Results showed that carcass yield was similar (P>0.05) and maximised (P<0.05) on 8 and 12% CF diets at 2800 and 3000ME (Kcal/kg) with the eviscerated weights of 1.40 and 1.42 kg respectively while carcass fat as per abdominal and gizzard was minimised on 12% CF diet at 2800ME (Kcal/kg) diet. Relative weights of both intestinal organs and length of intestine were increased (P<0.05) in broiler finishers with increasing CF levels while increasing ME levels increased abdominal fat. It can therefore, be concluded that 12% CF diet at 2800 and 3000 ME (Kcal/kg) maximised carcass yield but carcass fat was minimised at 2800 ME (Kcal/kg) diet of broiler chickens in favor of its recommendation for adoption, especially in the tropics.

This study was conducted on Black Bengal and crossbred goats thrives in the western part of Bangladesh for comparative evaluation of their carcass yield and meat quality. Thirty male goats (15 Black Bengal and 15 crossbreds) slaughtered in the slaughter house of Rajshahi city corporation were evaluated for carcass quantity and quality. The average slaughtering age was 12.60 and 12.40 months, and dressing percentage 43.71% and 45.86% for Black Bengal and crossbred goats, respectively. Crossbred goats had significantly (P<0.01%) higher dressing percentage than the Black Bengal goats. The total edible and non edible portions of Black Bengal and crossbred goats did not differ significantly (p>0.05). The percentage of moisture, crude protein, ether extract and ash contents were 72.79, 21.90, 3.72 and 1.15 for Black Bengal goat and 73.46, 20.85, 4.51 and 1.08 for crossbred goats, respectively. There was no significant difference (p>0.05) among moisture, crude protein, ash content (%) of Black Bengal and Crossbred goats. However, the carcass of crossbred goats contained more fat (ether extract) (p<0.05) compared to the Black Bengal goat. The higher carcass yield and dressing percentage observed in crossbred goats reflected to yield more meat compared to the Black Bengal goat.

THE EFFECT OF THE USE OF PAPAYA LEAVES SUBSTITUTED TO BASAL DIET ON THE PERCENTAGE OF CARCASS AND ABDOMINAL FAT PERCENTAGE OF BROILER CHICKEN. This study aims to determine the effect of papaya leaf meal substituted to basal diet on the carcass weight, percentage of carcass, and abdominal fat of broilers. This study used 80 unsexed broilers, day old chick (DOC). The experiment used a completely randomized design (CRD) consisting of 4 treatments and 5 replications. The arrangement of the experimental treatments was as follows: R₀ = 100% basal diet (BD), 0% papaya leaf meal (PLM), R₁ = 95% BD + 5% PLM, R₂ = 90% BD + 10% PLM, R₃ = 85% BD + 15% PLM. The results showed that partial replacement of the basal diet with with papaya leaf meal had no significant effect on carcass weight and the percentage of broiler abdominal fat. The treatment gave a very significant difference on the percentage of carcass. On carcass percentage results showed that R0 was highly significant different from R3 but not significantly different with R2 and R1. Treatment R1 was significantly different from R3 but not significantly different from R2, whereas between treatments R2 and R3 were significantly different. Based on the results of this study it can be stated that the use of papaya leaf meal up to level of 15% can produce a good proportion of carcass and abdominal fat. Keywords: broiler, papaya leaf meal, carcasses, abdominal fat.
