Abstract

The objective of the experiment was to evaluate the effect of lactation stages on the quality and flavor of 2 months ripened cheese. The experiment was conducted from December 2009 until April 2010. Five goats were used as samples. Milk were collected at 7 days and 30 days post kidding. Cheeses were coagulated using rennet which produced by extracting dried abomasum of 10 days old goat kid. Fresh cheeses were analyzed for its quality and kept for 2 months. After 2 month, ripened cheeses were analyzed for its quality and flavor. Parameters observed were cheese’s physical quality (cheese yield and tenderness), chemical quality (pH, protein, fat, moisture, ash, calcium) and flavor (for ripened cheeses). Cheese yield, tenderness, pH, protein, fat, moisture, ash, and calcium composition were analyzed using Repeated Measurement of General Linear Model and flavor quality was analyzed using Mann-Whitney Test. The result showed that lactation stages (7 and 30 days post kidding) did not significantly affect cheese yield, pH, protein, fat, and calcium but it had an effect on tenderness, moisture, and ash. Ripening significantly affected flavor such as salty, sour, bitter, and rancidity but not the sweet taste. Ripening was also affected pH and fat composition but moisture, ash, protein, calcium, and tenderness were not affected. It can be concluded that 2 stages of lactation did not significantly affect overall cheese quality, but it was suggested to choose milk from days 30 after partum as cheese raw material since cheeses from days 7 milk have a flavor defect (bitter) and this kind of milk is still needed by the kids ofthe goat.(Key words: Kaligesing race goat’s milk, Cheese quality, Cheese ripening, Cheese flavor, Stage of lactation)

Abstract

This experiment was aimed to evaluate the effect of katu leaves as feed supplement on milk production and milk composition of Ettawa Crossbred goat during early lactation. The experiment was conducted in the village of Kemirikebo, Girikerto, Turi, Sleman started from June, 27 until August, 27 2009. The experiment used 8 pregnant goats weighing 36 to 55 kg. The goats were divided into 2 treatments, those were control and treatment groups. The goats incontrol group received basal feed as much as 10% dry matter of body weight, consisted of calliandra and concentrates with a ratio of 9 to 1 respectively. The treated goats were fed with the same basal feed as those in the control group andsupplemented with katu leaves at 0,06% of bodyweight. The examination was conducted to collect data on feed intake, milk production, composition of colostrum and milk. Data were statistically analyzed with T-test. The result showed that katu leaves supplementation as much as 0,06% of body weight was able to increase protein level of colostrum significantly but had no significant effect on feed intake, milk production, and milk composition.(Key words: Ettawa Crossbred goat, Katu leaves, Milk production and composition)

Abstract

The objective of the study was to investigate rationality and allocative efficiency of the utilisation of production factors in smallholder dairy farmers. The study was conducted from June to August 2009 in the region of UPP Kaliurang cooperative, Sleman, Yogyakarta. There were forty respondents of smallholder dairy farmers taken by purposive sampling method. The primary data were taken from respondents and secondary data were from related institutions. Regression function of Cobb-Douglass model was used to determine the production factor which influenced milk production. Data were analysed based on unit/farmer. Coefficient of regression was estimated with Ordinary Least Square (OLS), further analysis was conducted by allocative efficiency. The result of this study showed that forage, concentrate, land owned/farmer, labor, number of livestock and percentage of lactating cows significantly affected the milk production (R2=0.78). Partially, percentage of lactating cows and total dairy cows had positive effect (P<0.01 and P<0.1) on the milk production of each farmer, however forage and concentrates did not affect the milk production. The result of allocative efficiency test showed that input consisted of forage and concentrates in this study have not achieved efficienly. Technically, the utilisation of production factors had not been rational, it was shown by the production elasticity (Ep) >1 (1.462).(Key words: Production of efficiency, Smallholder dairy farming, Factors of production)
