Pertambahan Bobot Badan dan Waktu Pembusukan Daging Ayam Broiler yang Diberi Ekstrak Jaloh Dikombinasi dengan Kromium
ABSTRACT: A study was
conducted on broiler chickens under heat stress to evaluate the effect of
combined jaloh (Salix tetrasperma Roxb) extract with chromium mineral in the
body weight, value of feed ratio conversion, and time to meat to become
decomposed. Twenty four of 20-day old Cobb female broiler chickens were
randomly assigned and divided to 4 treatment groups. Completely randomized
design was used in this study. The treatments were as follows: 1) chickens
given no heat stress and jaloh extract nor chromium (tCp); 2) chickens under
heat stress without given jaloh extract nor chromium (Cp); 3) chickens under
heat stress and given jaloh extract in 1.000 mg/lt drinking water (Cp+Ej); and
4) chickens under heat stress, given jaloh extract in 1.000 mg/lt drinking
water, and chromium in 1.000 ug/lt drinking water (Cp+Ej+Cr). Heat stress given
was 33 ± 1oC of cage temperature during 4 hours per day within 15 days. Jaloh
extract and chromium treatments in drinking water were given at 2 hour before
cage temperature reaching 33 ± 1oC and were stopped being given after 1 hour,
when cage temperature back to room temperature. On the 16th day of the study
chickens were measured before slaughtered. Samples obtained were chicken meat that
taken from breast part (musculus pectoralis). The result suggested that either
giving jaloh extract per se at the dose of 1.000 mg/lt in drinking water or
combine it with chromium that given two hours before cage temperature reaching
33 ± 1oC, can prevent chickens from decreasing their body weight, decreasing
value of feed ratio convertion, and extending time to meat to become
decomposed.
