| dc.description.abstract | M HARYONO SAMOSIR, 2015: “PREDICTION BODY WEIGHT OF
BRAHMAN CROSS BEEF CATTLE, BODY WEIGHT OF ACEH BEEF
CATTLE, BODY WEIGHT OF BALI BEEF CATTLE BASED ON BODY
LENGTH AND CHEST SIZE ”. Under supervised by HAMDAN dan
ARMYN DAULAY.
This study aimed to examine for more accurate formula to estimate
body weight based on body size (body length and chest size) on Brahman
cross beef cattle, Aceh beef cattle Aceh and Bali beef cattle. The experiment
was conducted at three different regions based on each nation is Brahman
cross cattle in PT Lembu Andalas Langkat (LAL), Aceh beef cattle in
BPTU Indrapuri Aceh and Bali beef cattle in the area of PTPN IV Siantar in
June to November 2014. The formula used in this study is the estimation
formula weight Schrool, Smith and Winter, as well as using correlation and
multiple regression analysis to test the research data.
The results showed that the test results obtained by regression
analysis, correlation and determination showed Brahman Cross beef cattle,
Aceh beef cattle and Bali beef cattle showed a significant relationship
between body length, chest size with body weight. Estimation of body weight
in Brahman cross beef cattle the closest is to use the formula Schrool the
percentage deviation of 0.15%, the closest Aceh beef cattle by using the
formula Winter with the percentage deviation of 0.03% and the Bali beef
cattle that comes closest is to use the regression equation percentage
deviation of 0%. | en_US |
