Records kept by the Bauchi Meat Company, on 2,264 cattle slaughtered for meat, form 1982, were analysed to study the influence of season and year on the weight of the body, carcass, bone, wholesale and retail cuts, and dressing percentage. Bothe season and year showed significant (P < 0.01) influence on triats measured. Body weight was lowest during the rains (345.39 ± 3.00kg) increasing steadily thereafter to attain its highest peak (397.87 ± 3.30kg) in the hot-dry season. Body weight were similar in 1982 (370.63 ± 3.91kg) and 1984 (365.24 ± 2.39kg) but superior (P < 0.01) to that of 1983 (357.63 ± 2.61kg) Warm carcass weight was highest in the hot-dry season (217.11 ± 2.05kg) and lowest in the cod-dry season (181.64 ± 1.96kg). The annual values were similar for 1982 and 1984 but superior (P < 0.01) to that of 1983 (183.80 ± 1.43kg). The wholesale and retail cuts were heaviest in the hot-dry season. The dressing percentage was highest in the rainy season (56.13 ± 0.12%) and lowest (49.81 ± 0.21%) in the cold-dry season (P < 0.01). On annual basis carcasses dressed best in 1984. (55.26 ± 0.07%) and least (53.17 ± 0.12) in 1982. Studies such as this conducted through many season, years and even decades are valuable in functional planning.

Two experiments were carried out with Hereford and Aberdeen Angus steer calves to study the influence of feeding concentrate and hay in the ratios of 1:2, 1:1, 2:1; of feeding the concentrate in the pelleted and the ground form; of pelleting the entire ration; and of feeding the ration ad libitum and according to the body weight of the animal. All comparisons were not made in each experiment. Each lot in each experiment was made up of four Aberdeen Angus and seven Hereford calves. All animals were fed individually. Only the data obtained between 500 and 900 lb. body weight were considered in this paper. The animals were slaughtered as they reached 900 lb. and certain carcass data obtained.The steers fed concentrate to hay in the ratio of 1:2 made smaller daily gains, required more feed (T.D.N.) per unit of gain, had lower dressing percentages, and had less fat in their 9-10-11 rib sections than those fed rations with ratios of concentrate to hay of 1:1 and 2:1. The steers fed the 1:1 ratio made significantly smaller daily gains and required more feed per unit of gain than those fed the 2:1 ratio of concentrate to hay, but were not different in dressing percentage or percentage fat in the 9-10-11 rib sections.There were no significant differences between those steers fed their concentrate in the pelleted or ground forms. In one experiment, pelleting the entire ration resulted in significantly lower daily gains than pelleting only the concentrate and feeding the hay chopped, but in the other experiment there were no differences. Pelleting the entire ration resulted in no significant differences in feed efficiency, dressing percentage, or carcass grade. Limiting the daily consumption of feed to predetermined amounts dependent upon body weight did not influence efficiency of feed utilization or carcass characteristics as compared to ad libitum feeding.The Hereford steers that were fed in these two experiments made greater body gains per unit of feed consumed but had less body fat and in one experiment had lower grading carcasses than the Aberdeen Angus steers.

Maternal Administration

The effects of salbutamol administration to pregnant sows on post-natal growth and carcass characteristics of the progeny were investigated. Salbutamol (4 mg/kg diet) was fed to sows during the first (0 to 38 days, TI), second (39 to 78 days, T2) or third (79 days to term, T3) trimester of pregnancy. At birth, maternal administration of salbutamol had no effect on body weight, dressing percentage or weights of liver, heart, semimembranosus and semitendinosus muscle in proportion to body weight in the progeny. No significant effects of maternal treatment with salbutamol on body weight, dressing percentage, semitendinosus muscle weight in proportion to body weight and loin eye area were observed in the progeny at 21 days. P2 fat depth at 21 days was greater (P < 0-05) in TI than in controls. The percentage of type I fibres in the deep portion of semitendinosus muscle was higher (P < 0.05) in treatment groups as compared with controls: 27.4, 42.8, 36.9 and 36.0% in control, TI, T2 and T3 respectively. At slaughter (90 kg), carcass and meat parameters including length, P2 fat depth, meat colour and drip loss were not affected by maternal administration of salbutamol. However, loin eye areas were larger in T1 than in controls. Larger loin eye areas, coupled with numerically (but not statistically) significant heavier carcasses and lower backfats, resulted in greater estimates of carcass protein mass in TI pigs as compared with controls (P = 0.06).

The objective was to evaluate the effect of the substitution (0, 33, 66 and 100%) of corn by cassava wastewater dregs on carcass characteristics and non-carcass components of crossbred Santa Inês lambs. Forty male sheep, uncastrated with an average initial body weight of 20 ± 1.87 kg and five months of age, were used. These were housed in individual pens in a randomized block design with four treatments and ten repetitions and slaughtered after 70 days of confinement. Quadratic effect (P &lt; 0.05) was observed for the empty body weight (EBW), hot carcass weight (HCW) and cold carcass weight (CCW) and carcass compactness index (CCI), with maximum points of 36.14, 19.45, 20.20 and 0.31 kg cm-1 for the replacement level of corn for cassava wastewater dregs, 50.0, 53.84, 54.04 and 45.45% respectively. There was also an effect (P &lt; 0.05) on the weights of the rumen and “Buchada”, with maximum points of 0.909 and 6.25 kg per replacement level, 49.11 and 51.29% respectively. As for retail cuts, only the efficiency of the leg was altered (P &lt; 0.05), having a linear increase while the other variables were not affected. Cassava wastewater dregs can be used in full as an alternative food in the diet of feedlot lambs without harming the main carcass characteristics and non-carcass components.

The study was conducted to determine growth, slaughter, and carcass characteristics of Lindovskaya geese. While a total of 237 goslings, 101 males, and 136 females were used to determine their growth characteristics, 16 male geese in total were used for the detection of the slaughter and carcass characteristics. Each slaughter group (12 weeks and 16 weeks old) consisted of 8 male geese. It was determined that the effect of sex on body weight values by week was significant (P < 0.05). In addition to this, the body weights of male geese were higher than the body weights of the female geese in all weeks. In the study, it was determined that the effect of the slaughter age on the weights of slaughter, head, blood, intestinal fat, and abdominal fat was significant (P < 0.05). Additionally, the values of the geese slaughtered at 16 weeks were higher compared to the geese slaughtered at 12 weeks. It was detected that the effect of slaughter age on the weight of the hot carcass, cold carcass, neck, breast and back, and other parts were significant (P < 0.05). Moreover, it was concluded that these values increased as the slaughter age increased. As a result, it can be said that slaughter age at 16 weeks was more preferable than at 12weeks under breeder conditions. Additionally, it has been revealed that Lindovskaya geese need to be reared under controlled conditions, with regular care and feeding, to obtain better results.

The present study was designed to evaluate the relationship between the body measurements (BMs) and carcass characteristics of hair sheep lambs. Twenty hours before slaughter, the shrunk body weight (SBW) and BMs were recorded. The BMs involved were height at withers (HW), rib depth (RD), body diagonal length (BDL), body length (BL), pelvic girdle length (PGL), rump depth (RuD), rump height (RH), pin-bone width (PBW), hook-bone width (HBW), abdomen width (AW), girth (GC), and abdomen circumference (AC). After slaughter, the carcasses were weighed and chilled for 24 h at 1 °C, and then were split by the dorsal midline. The left-half was dissected into total soft tissues (muscle + fat; TST) and bone (BON), which were weighed separately. The weights of viscera and organs (VIS), internal fat (IF), and offals (OFF—skin, head, feet, tail, and blood) were also recorded. The equations obtained for predicting SBW, HCW, and CCW had an r2 ranging from 0.89 to 0.99, and those for predicting the TST and BON had an r2 ranging from 0.74 to 0.91, demonstrating satisfactory accuracy. Our results indicated that use of BMs could accurately and precisely be used as a useful tool for predicting carcass characteristics of hair sheep lambs.

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.

An experiment was conducted at the University Poultry and Duck Farm, Mannuthy, Kerala to study the effect of individual selection on growth and carcass characteristics in Kuttanad ducks. One thousand and eighty-eight day-old Kuttanad ducklings procured from progressive farmers of Kerala formed the base generation (S0). Based on body weight at eighth week, top 150 females and 25 males were selected through individual selection. From the 25 sire families, 979, 969 and 1610 ducklings were produced by artificial insemination in S1, S2 and S3 generation in pedigreed hatches. Body weight was recorded at fortnightly intervals till 12th week of age and at 18th and 40th week of age in each generation. Carcass characteristics were evaluated at 8, 10 and 12 weeks of age in four generations. An improvement of 270.51 g could be recorded at 8 weeks in S3 generation. The period of active weight gain shifted to 4th and 6th week in S3 generation whereas it was 8th week in the previous generations. The results also indicated that a compensatory growth mechanism is present in ducks and they attain 90 per cent of the adult body weight by 12 weeks of age. The carcass characteristics showed that there was improvement in the dressing percentage over generations and S3 generation attained the highest yield at 8 weeks. Hence, selection for body weight at 8 weeks was effective in improving the body weight and they could attain its optimum meat production characteristics at 8 weeks and hence it could be considered as the ideal age for processing.
