dc.description.abstractEighteen post lactating dairy cows in the highland Tajur Halang Bogor, were used to acsess physiological condition and efficiency of increasing milk production dosed with bovine somatotropin (bST). The experimental cows were assigned into a Randomized Block Design with a 3x2 factorial arrangement. The first factor was using somatotropin (bST) with three levels (non bST injection, biweekly injection and triweekly injection). The second factor was lactation periodes with two levels (4th lactating time and 6th lactating time) Parameters measured were heart rate, respiration frequency, rectal temperature, weight gain, dry matter intake, milk production efficiency and body condition score, milk production, 4% FCM (fat corrected milk.), milk composition, weight gain, milk quality consist of protein, fat, pH. Bovine somatotropin significantly increased heart rate and respiration rate. Also bovine somatotropin injection at 4th lactating time significantly increased milk production. There were an interaction between bST dan lactating time on milk production and weight gain. Bovine somatotropin injection biweekly in cows on 4th lactating timeration increased milk production by 28 – 30%, but injection in cows 6th lactating time increased milk production by 17 – 20% combination with somatotropin dose 250/ml/14 days. Biweekly and triweekly somatotropin supplementation did significantly affect milk production.id
