Improving Carcass Quality of Indigenous Cattle of West Sumatera Fed Local Feed Resources

Khasrad and R.W.S. Ningrat    

Abstract: Lack of adequate nutrition all year round is one of the major causes of the low productivity of ruminants. An operational policy announced by the Indonesian government to achieve the target to be self sufficient on meat demand 2010 is to develop feed and ration for beef industry based on agricultural and industrial-wastes besides exploiting biodiversity that has not been fully implemented by the farmers. A feeding trial with 12 Pesisir cattle, indigenous cattle of West Sumatera weighed 120-150 kg aged 2-3 yrs old were carried out to investigate the effect of feeding local feed resources on their growth performance and carcass characteristics; dressing percentage, rib eye area, lean and fat percentage. Animals were divided into two equal groups of similar average body weight, assigned to Completely Randomized Design and were individually fed for 90 days. The first group was offered control feed as practiced by farmer and the second group was offered treatment diet based on ammoniated rice straw and chipped cassava. This feeding trial was followed by a slaughter experiment on one animal from each group to study of carcass traits. Cattle receiving a treatment diet performed better (p<0.05) in all parameters measured, than those receiving control diets. There was significant difference (p>0.05) observed between the two groups with regard to Average Total Body Weight Gain (ATG) and Average Daily Body Weight Gain (ADG) 0.20 kg/d to 0.68 kg/d respectively. Dressing percentage was significantly higher in treatment diet (52.59%) than in control diet (50.82%). The rib eye area, lean and fat percentage was significantly higher in treatment diet than in control diet. It was concluded that feeding improved low quality local feed resources could have a positive effects on growth performance and carcass traits of indigenous cattle.
