Twenty-three of indigenous Priangan and Javanese Fat-tailed (JFT) ram breeds were used to evaluate its carcass and non carcass components slaughtered at mature live weight. Five Priangan rams and six JFT rams were slaughtered at 32.5 kg of live weight while six other rams of each breeds were also slaughtered at 40 kg of live weight. Before the rams were slaughtered, they were fattened using pellet ration which was formulated according to NRC for fattening 10 kg of lamb, containing 73.3% TDN and 16% protein in dry matter bases. Feed and water were given ad libitum. Rams were slaughtered and dissected when they reached their assigned slaughter weight (32.5 and 40 kg). The results showed that both breeds had high percentage of carcass (53%-55%) with no significantly different between breeds (P>0.05) either were slaughtered at 32.5 kg or 40 kg. However, carcass of Priangan rams had significantly more muscle, but less fat than Javanese Fat-tailed rams at mature live weight (P<0.05). Non-carcass components were not significantly different between breeds (P>0.05) except for head, tail and testes (P<0.01) and liver (P<0.05). The edible and inedible portion of non-carcass ranged from 30%-32% and 12%-15% of slaughter weight, respectively.
1. Results of an 8-year (1981 to 1988) period of breeding geese for egg production and crammed liver weight, including phenotypic and/or genetic parameters for various traits (1982 to 1985), as well as line tests (1987 to 1988), are summarised for two lines. 2. The regressed annual genetic gains over years were 2.7 eggs and 30.8 g crammed liver. However, there was a decline in the rate of genetic progress after 4 years of selection. 3. Heritability estimates were found to be relatively high for most traits, whereas phenotypic and genetic correlation coefficients between traits were rather low, as would be expected from lines not previously subjected to an intense selection programme. 4. Phenotypic correlation coefficients between part-period records and full-period egg production, suggest that 3-month (October to December) records may be adequate to identify most of the best first-year layers. However, sexual maturity should be treated as a separate trait. 5. The cross between the 'Grey' (male) line, superior in crammed liver weight, and the 'White' (female) line, excelling in egg production, seems to be superior to the pure lines, in a fully-integrated enterprise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
