Abstract

A survey in the agribusiness of dairy goat smallholder had been conducted in Kaligesing district of Purworejo region at 13 rd September up to 7th November 2001. The survey studied the factors effecting the milk yield, in how the factors influence economically. Forty eight respondents (dairy goat smallholders) were used in this study and interview method was applied for collecting data. The variables were observed; lactation goat, man power, garage, and concentrate ration. Cobb-Douglass method was applied for analyzing the data. To know the economic efficiency of the agribusiness was approached by the ratio between the Marginal Product Value an input cost. From the data analysis it could be in formatted that the numbers of lactating goat and the numbers of lactating goat and the numbers of concentrate were significant influence on the milk yield, white the man power and the forage were not significant influence. For the numbers of lactating goat and concentrate, economically the efficiency was not yet reached, so the use of the factors were ought to be increased up to an appoint limited. On the other hand the man power and forage was not efficient, so the use of the factors need to be descreased.

Abstract

A survey on smallholder dairy cow had conducted in Banyumas region from November 8th 1999 up to February 8th 2000. Forty six respondents were involved in this study (as samples). Cobb - Douglas analysis was applied in this survey. From the study can be concluded that a small holder owned 3.02 heads of dairy cow (2.2  ST), 1.44 heads of lactating cow with 9.77 L/day milk production on average. The benefit of the backyard farming was RP.70.603,225 per month on average. Feeding was the biggest influence on benefit because feed cost was 65.81 percent from the production cost. The milk production function , by the equation: Y = 0,8958 X1⁰·⁰³³² X2 0.049 X30.168 X40.608 The four variables can explain 92.4 percent (R²=0,924)on the milk  production variation .It can be suggested that to improve milk production on dairy cows can be done by intensifying labour, and improving the forage feeding.

Abstract

Protein is one of the nutrient components in milk that is related to product quality. The components of milk protein are divided into casein alpha-s1, beta, alpha-s2, kappa, and whey fractions such as alpha lactalbumin and beta lactoglobulin. There are no existing data of milk protein fraction in dairy cow and goats in Banyumas Regency. This study aimed to determine the profile in form of protein fractions of cow and goat milk in Banyumas. Milk sample from fifty cows and thirty dairy goats was taken by random sampling in some areas. The milk protein profile was identified by the technique of sodium dodecyl sulphate gel electrophoresis (SDS-PAGE) and protein quantity prediction by software. The data obtained were analyzed statistically by Mann-Whitney between cows and goats. The results were significantly different (p<0.05) between cows and goats in molecular weight of protein alpha-S1 casein (29.66 vs 33.37 kDa), alpha-S2 (27.76 vs 29.49 kDa), beta (24 , 48 vs 25.59 kDa) and beta lactoglobulin (15.75 vs 15.97 kDa). The quantity of casein alpha-S1 (7.88 vs 4.16 g/l), alpha-S2 (1.31 vs. 4.02 g/l), beta (8.74 vs 14.24 g/l), kappa (2.41 vs. 4.28 g/l) and alpha lactalbumin (0.91 vs 0.7 g / l) was significantly different (p <0.05) between cow's and goat's milk, respectively. In conclusion, milk protein profile of cows and goats in Banyumas Regency is different.
