Abstract

The present study was designed to evaluate factors affecting goat’s milk quality, consumer’s satisfaction to goat’s milk, and technical responses associated with goat’s milk quality. Three farms having more than 100 dairy goats were purposively selected for the study. Thirty consumers were determined by using judgement sampling techniques to assess the satisfaction of consumer to goat’s milk quality. Data were analyzed by using fishbone diagram and House of Quality matrix. The study revealed that milk quality produced by dairy goat farms met the standard quality of milk composition namely; specific gravity, total solid, fat, protein, and total solid non-fat. The main factors affecting goat milk quantity and quality were the quality of does, pregnancy status, number of kids per birth, shape and size of the udder, lactation length, and the health status of the goat. The attributes of goat’s milk that were able to achieve customer’s satisfaction targets were nutritional content, packaging size, and goat milk color. Technical responses that were major concern in ensuring goat’s milk quality included goat breed quality and health conditions, skills and performances of farmers and employees, feed quality, farm equipment hygiene and completeness, cleanliness, and hygiene of livestock housing and environment. Technical response on livestock health condition was the first priority to be improved.Key words:  goat milk, consumer’s satisfaction

Abstract

Environmental conditions pose direct and indirect effects on animal growth. Animal growth  itself can be defined in many ways, and one of the parameters is body growth. This study was conducted to determine the dimensions of body measurements such as shoulder height (SH), body length (BL), chest width (CW), and heart girth (HG) of calves and heifer located in high land, middle land, and low land. The number of calves and heifer used in this study was 121 and 131, respectively. Calipster and rondo ribbon were used to measure the body measurements while the Gompertz model was used to predict the growth parameters of mature age. The results indicated that the maturity age of cattle raised in the high land, middle land, and low land were 347.63 - 371.52 days, 377.58 days, and 465.69 days, respectively. The growth rate for all body measurements (SH, BL, CW, HG) was higher in the high land compared to the middle land and low land. The sequences of growth development obtained from the Gompertz analysis was SH, CW, HG, and BL. Heifer reaching earlier puberty or mature age will have better body size.

Abstract

During for the past 10 years, milk production in Indonesia has been on the increase of approximately 70% (FAO, 2002), but it can only meet 30% of domestic needs for milk. The remaining 70% is still imported, mostly from Australia and New Zealand. Milk production in Indonesia is expected to increase to achieve an average of 15-20 liters/cow/day. It is necessary to analyze dairy enterprises to assess its feasibility. The objectives of this study were: (1) to evaluate production technology of small holder dairy farm in West Java, Central Java and East Java; (2) to analyze the efficiency of the existing dairy farming. Twenty farmers from each localities with ownership less than or equal to 10 cows, consisted of small (<4 cows), medium (4-6 cows), and large (> 6 cows) scales were interviewed on their businesses. Economic analysis on net profit indicated by BC-Ratio, and IRR values. The dairy farming in West Java, Central Java and East Java was carried out traditionally without technological diversification, the main products were pasteurised fresh milk. Milk production was low (10 liters/cow/day). Net income of Rp 1,521,820/m/farmers, BC-Ratio 1.32, and IRR 17% indicated a low result. Improving cows ownership should be in line with the improved management and technology application.

Abstract

Animal feeds with the requirements were given to support production and productivity of livestock. Production and productivity were related with feed consumption and digestibility. Superior grass that was given without cutted causing a lot of wasted parts, so the grass size would be cutted to see an increase in feed consumption and digestibility, and milk production efficiency. The study was conducted on July-October 2013 in Field Laboratory of Animal Husbandry IPB, using four lactation dairy cattle. The research designs were RBSL and analyzed by ANOVA on the four stage treatment with feed consumption, digestibility, and milk production efficiency as observed variables. The results showed that cage condition and environmental could potentially caused mild to moderate stress (THI : 68–90), the size of grass cutted were not significant effect to the digestibility of Dry Material (BK), Crude Fat (LK), Crude Fiber (SK), BETN and TDN but significant effect to the digestibility of crude protein (P<0.05). Digestibility of proteins on cutting size in 5 cm (66.35 ± 5.29%) and 15 cm (67.44 ± 4.83%) higher than controls (63.40 ± 7.65%) and 10 cm (64.61 ± 5.92%). Treatments of the grass cutting were not significant effect to dry material and feces, as well as the efficiency of dry material, crude protein and crude fat were not significantly affect the size of elephant grass clippings. The size pieces of grass were not effect to feed consumption, efficiency and nutrient digestibility of feed but effect on protein digestibility.
