“…The mean dressing out percentages varied between 38% and 44%, which generally agrees with the values reported for various goat breeds worldwide (Devendra & Owen, 1983, Kadim et al, 2004 as well as the large southern African goats (Owen & Norman, 1977;Simela et al, 2000). For the latter breeds, Owen & Norman (1977) obtained values ranging from 43.1% for milk-teeth kids to 48.3% for 8-teeth castrated Tswana goats.…”

“…Owen, 1975;Mukherjee et al, 1981;Mukherjee et al, 1986;Simela et al, 2000;Atta & El Khidir, 2004). The live weight, chest girth and carcass measurements of the goats used in this study compare well to other breeds in the region, namely the Tswana goats of Botswana (Fisher et al, 1976;Owen & Norman, 1977) and the Matebele goats of Zimbabwe (Simela et al, 2000), for example; the reported mean chest girth for castrated Matebele goats ranged from 59.8 cm to 83.3 cm between the milk-and 8-teeth stages (Simela et al, 2000). The average live weight of these castrates when they are marketed in the commercial sector ranged from a stipulated minimum of 25 kg (Hatendi, 1993) to about 41 kg at the 6-teeth stage (Simela et al, 2000).…”

“…The side length of Tswana castrated goats ranged from 55.3 cm at the milk-teeth stage to 64.4 cm at the 6-teeth stage (Owen & Norman, 1977), respectively. The corresponding range of live weights was 24 kg to 41 kg and the carcass weights of the milk-, 2-, 4-and 6-teeth castrates were 9.89 kg, 11.69 kg and 13.87 kg and 17.67 kg, respectively.…”

Eighty-nine intact male, castrates and female South African indigenous goats in three age groups (0, 2 -6 and 8 permanent incisors) and two pre-slaughter conditioning groups; namely, the non-conditioned which were slaughtered within three months of purchase and the pre-slaughter conditioned, which were slaughtered 6 -10 months after purchase or birth were used. The effect of sex, age and pre-slaughter conditioning on live animal, carcass dimensions and carcass composition were evaluated. The goats were large with live weight, carcass weight and carcass dimensions in the range of the large breeds of southern Africa. They had a high lean and low fat content. Intact males were suited for high chevon yield because they were heavy, had a high lean and low fat content, and losses during dressing and chilling were reduced by improved nutrition. Goats between 2 -6 teeth yielded heavy carcasses that were comparable to goats in the 8-teeth group, and had proportionately more lean and less carcass fat. The hind limb was ideal for high lean and low fat, high value cuts but the dorsal trunk was bony and yielded less lean. Pre-slaughter conditioning improved the overall size of the goats and reduced the losses during slaughter and chilling. It also improved the lean/bone and lean and fat/bone indices. _______________________________________________________________________________________

“…In many parts of the world, considerable attention has been directed on studies relating to carcass evaluation and body composition of meat animals (Owen andNorman, 1977: Joksimovic andOgnjanovic, 1977) including snails (Ajayi, et al, 1978). This is partly for providing information necessary for a full evaluation of improvements in nutrition, general management and genetic up-grading of the meat animals under consideration and partly because the knowledge of (and information on) the size and weight of the edible portion as well as the chemical composition from a particular type of animal can greatly assist in more efficient marketing or pricing of such an animal.…”

Yield of different parts of snail (Archachatina marginata) was obtained by collecting 100 snails at random from Ibagwa-Aka in Igbo-Eze local Government Area of Enugu State and weighing each snail and its parts i.e. the shell, foot (edible portion) and offal (composed of the viscera, blood and slime) and the proximate composition of the edible portion (foot) was obtained. Thereafter, onekilogram portions of the foot were cured for 16h by immersing and equilibrating (under room conditions) in one liter of solution containing 0%, 10%, 20% and 30% salt. The samples were draindried after curing and analyzed. Results show that the edible portion (foot) accounted for about 38.5% of the live weight of the snail while the inedible portion accounted for more than 60%. While all parts increased quantitatively as the snail increased in size, the shell was accumulated more and at the expense of the foot and offal. Proximate analysis suggests that the moisture content (79.5%) and crude protein (18.9%) approximated those of raw beef muscle. During curing, moisture content and water activity decreased as the concentration of salt in the curing solution increased, presumably due to osmotic dehydration. Moisture content, water activity and pH reduced further during storage. However, those samples treated with 30% salt maintained lower moisture and water activity through storage compared with other samples. Peroxide value and total viable microorganisms increased in all samples during storage but salt treatment increased rancidity while inhibiting the growth of microorganisms.

The aim of this study was to characterise ultrasound measurements of live and carcass traits in intact males, females and castrated Tswana goat kids from birth to 12 months of age raised under semi-intensive system in South-eastern Botswana. Measurements were recorded in 15 castrates, 15 intact males and 15 female Tswana goat kids randomly selected at birth. Ultrasonic fat and muscle depths were measured at the first, third/fourth, sixth/seventh, ninth/tenth and 12th/13th thoracic; first, third and fifth lumbar and first, second/third and fourth/fifth sternal vertebrae, fortnightly for the first 6 months and then monthly for the remaining 6 months. The animals were stunned and humanely slaughtered at 12 months of age, and ultrasound and shatterproof ruler were used to measure fat and muscle depths on the carcasses at similar sites as on live animals. A real-time B-mode ultrasound scanner fitted with LV2-1 probe operating at 7.5 MHz (Explorer V5 Vet Laptop B-Ultrasonic Scanner UMC Technology Development Co., Ltd, China) was used to predict ultrasound measurements on live animals and their carcasses. Data were analysed using general linear model in statistical analysis system. Muscle depth measurements increased significantly (p < 0.05) with age in all sites of measurements. However, there was no significant difference between the sexes at different sites of muscle depth measurements at the same age. Muscle depth at the sternal vertebrae was significantly deeper (almost 55 mm at 12 months of age) than 16 mm at thoracic and 16 mm at lumbar vertebrae at 12 and 8 months of age, respectively. No subcutaneous fat depth measurements were recorded in the lumbar vertebrae (0.00 ± 0.00) and the thoracic (0.00 ± 0.00) regions in all sex groups. However, fourth and fifth sternal vertebrae showed considerably deeper amount of subcutaneous fat suitable for taking fat measurements as age increases (2.07 ± 0.23 mm females, 1.50 ± 0.43 mm intact males and 1.80 ± 0.38 mm castrates) at 12 months of age. All correlations between live and carcass ultrasound measurements and also between ultrasound carcass and ruler measurements were very high (r (2) = 0.96 to 1.00) for all the sexes indicating that live ultrasound measurements are suitable for use in this meat breed. More research is needed to evaluate the relationships between live ultrasonic measurements and carcass yield in the different sexes of Tswana goat kids.
