Abstract
The study was aimed to determine the influence of age and slaughter weight on carcass and non-carcass (head, skin, and digestive tract) of local sheep. Sixty local sheeps consisted of thirty local female sheep with slaughter weight 15-19,99 kg and thirty local sheeps with slaughter weight 20-25 kg, consisted of age less than one year, 1-1,5 years, and 2- 3 years. Data collected included age, slaughter weight, carcass weight, non-carcass ( weight of head, skin, and digestive tract), carcass percentage, and non-carcass percentage. Data were analyzed in a 2 x 3 factorial design. The first factor was slaughte r weight and the second factor was the age of local sheep. The difference between means was analyzed using Duncan ’ s Multiple Range Test (DMRT). The result s showed that slaughter weight significantly(P<0.05) influenced carcass and non-carcass per c entage. Age of local sheep significantly (P<0,05) influenced carcass percentage, skin percentage, and digestive trac t percentage. Therefore it could be concluded that the slaughter weight significantly influenced carcass and non-carcass and age significantly influenced carcass and non-carcass percentage, except legs per c entage. In conclusion, age dan body weight gave to increase the per c entage of carcass dan non-carcass. There was no interaction between the age of local sheep and slaugh t er weight on the carcass and non-carcass per c entage. Keywords: Local sheep, slaughter weight, age, carcass, non-carcass
Highlights
Sheep is one of the potential meatproducing livestock commodities
Butchers or Abattoirs like ewes because the price is relatively cheaper than rams, so the benefits will be greater than the cutting of rams. Seeing this background it is necessary to research the effect of age and slaughter weight on female local sheep carcass production
The observed variables are the percentage of carcasses and the percentage of non-carcasses
Summary
Sheep is one of the potential meatproducing livestock commodities. The ability to produce sheep meat is relatively fast compared to large ruminant livestock. The high factor of the price of male cattle on the animal market due to limited numbers, it makes the slaughterers choose to slaughter female sheep whose prices are relatively cheaper. Soeparno (2005) states that the carcass production of livestock is influenced by several factors including gender, age, and nutrition. The edible offal part consists of the head (brain, tongue, and head muscles), blood, trachea, lungs, liver, spleen, heart, pancreas, skin, and feet as well as the digestive tract and non-edible offal parts, namely the horns, nails, and bones. Butchers or Abattoirs like ewes because the price is relatively cheaper than rams, so the benefits will be greater than the cutting of rams Seeing this background it is necessary to research the effect of age and slaughter weight on female local sheep carcass production
