Abstract

ABSTRACT.The research to study the effect of correlation between male and female local cross goat with hairsheep to performance. The parameters were body weight, body length, sholder height, heart girth and chest of heart girth. Result of the research shows that there were very significant between age and all prameters cros goats above. The regretion of body weight with age, body length with age, shoulder height with age, heart girth with age and chest of heart girth with age to crossing local goats and male hairsheep were = 2.07 + 0.62 X, = 18,58 + 1.50 X, = 32.97 + 0.84 X, = 31.49 + 1,50 X, and = 13.98 + 0.51 X, respectively. The following regretion of female goats to body weight with age, body length with age, shoulder height with age, heart girth with age and chest of heart girth with age were = 2.10 + 0.50 X, = 17.96 + 1.53 X, = 32.06 + 0.81 X, = 30.69 + 1.51 X and = 13.27 + 0.34 X, respectively.

Abstract

ABSTRACT. The production of Casein hydrolysate with an extracellular proteinase from Lactobacillus helveticus CP790, was fractionated by two-step reverse phase heigh performance liquid chromatography. Only 1 fraction showed antihypertensive activity as measured by systolic blood pressure in spontaneously hypertensive rats after oral adsministration. Ten peptides in the fraction were further purified and identified by analisys of amino acid sequences. Each identified peptide was chemically synthesized, and the ant.ihypertensive activity of each peptide was evaluated in spontaneously hypertensive rats. The synthetic peptide with a sequence of Lys-Val-Leu-Pro-Val-Pro-Gln, found in -casein, indicated strong antihypertensive activity from 2 to 10 h after oral adsministration of 2 mg of peptide/kg of BW, and the effect was maximal at 6 h after oral adsministration. Moreover, the antihypertensive effect of the peptide was dependent on the dosage of peptide from 0.5 to 2 mg o peptide/kg of BW.

Abstract

ABSTRACT.The research has been conducted at Laboratory of animal product technology, Agriculture Faculty, Syiah Kuala University. This aimed of the research to study the different of composition of fat and milk protein to Etawah goats at the firs and fourth laction. The results showed that there were do not significantly different (P0.05) between the composition of fat and milk protein at the first lactation and the fourth lactatation. Composition of fat and milk protein at the first lactation was 3.966% and 3.336%. Wheras at the forth lactation were 4.016% to milk fat and 3.354% to milk protein composition.

Abstract

Analyze of Etawas milk goat quality sterilized at the Different Temperature and TimeABSTRACT. The objective of this experiment is to study the quality of sterilization of etawas goat milk at different temperature (110oC and 120oC) and different time (3 second and 6 second). The quality of sterilization of etawas goat milk was evaluated by measuring crude protein, crude fat, pH value and amount of microorganism. The study used a factorial completely randomizes design. The result showed that the different temperature and time of sterilized goat milk have not significant (P0,05) on crude protein, crude fat, pH value and amount of microorganism. The result also showed that no interaction between temperature and time. The conclusion of the research indicated that all the experiment have the same quality.
