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

Dairy cattle productive period is the best time to earned income. This is strongly influenced by the age factor of the first calving and the milk yield production. Based on that, this research conducted to analyze the differences effect of the age of first calving and calving interval on lactation period. The performance of the productivity period dairy cattle to the age of the first calving, calving interval, the empty period, the dry period and the milk yield. This research uses recorded production data from Dairy Cattle Breeding Center (BPT-SP and HMT) Cikole. The data consists of 42 productive dairy cows during the 2011-2017 maintenance period. The data were grouped by age of first calving K1: age of first calving 22-25 months; K2: age of first calving 26-29 months; K3: age of first calving 30-33 months; K4: age of first calving 34-37 months. The results showed that grouping of the first age calving was significanly in each group K1, K2, K3 and K4. The was significanly effect also exists on total milk production of first and second lactation periods in K1 and K2 more than K3 and K4.The results of the analysis the first calving relationship with the production of first and second lactation  decreased milk yield production during the lactation period.
