Abstract

This aims of this study was to estimate the bodyweight of FH dairy cows from birth to first child by knowing growth patterns and creating a standard curve for dairy cattle growth at BBPTU-HPT Baturraden dairy cow in Baturraden district, Banyumas Regency, Purwokerto, Central Java. Data obtained in the form of secondary data from births in 2005-2016 were 1437 tails and primary data were 353 tails. Data were analyzed using SAS 9.4 program with NLIN procedures (Non-Linear) using Gompertz models. The results show that the Gompertz models is easy in the calculation process with the data deviations that are close to the field of data and the models have a high degree of accuracy with the coefficient of determination (R2 ) 99.83%. The conclusion of this study is that the resulting curve of the Gompertz model can be used as a standard growth curve of Friesian Holstein dairy cattle in Indonesia from birth to first calf.

Abstract

The research objective was to determine the profile of smallholder farms based on the aspects of feed management and animal health in different agro-ecosystems on Timor Island. The research was carried out for 6 months, from June to December 2018. The research location was determined by purposive sampling, namely (1) pasture agroecosystem in District of Belu, Malaka, and Timor Tengah Utara, (2) agricultural agroecosystem in Kupang Regency and Kupang City, (3) plantation agroecosystems in Kupang Regency, and (4) forest agroecosystems in District of Timor Tengah Selatan. The purposive stratified proportional sampling method was used to determine the number of samples according to the Slovin formula at an error probability of 0.05 (5%) so that the sampling of respondents was 436 people. Types of data used are primary and secondary data with data methods by observation, interviews (questionnaires), and documentation. Descriptive quantitative data analysis described in a narrative manner. The results showed that for the aspect of feed management, feed preservation was only done by some farmers, with the highest to lowest percentage of actors being plantation agroecosystems (12.8%), agriculture, (5.9%), pasture (1.6%) and forest (0%). Whereas in the aspect of livestock health, the highest to lowest vaccination implementers were carried out in agricultural agroecosystems (98.0%) followed by plantations (92.2%), pasture (66.9%) and forests (44.8%).
