Judul: New Initiative to Build a Breeding Business of Bali Cattle Based on Community in Field Station of Sekolah Peternakan Rakyat (SL-SPR)
Abstrak: The government has launched a meat self-sufficiency program to meet meat needs since 2005. The main target was to increase the population of cattle in smallholder farmers. The problem is that there are no records and data on smallholder farmers so that it is difficult to increase the population of cattle. The purpose of this study was to (1) produce baseline data on the productive and reproductive performance of Bali cattle and their supporting factors which are used as the basis for starting recording at SL-SPR Maju Bersama (2) to analyze the carrying capacity with feed production and the carrying capacity index of forage land (3) to analyze the projection of Bali cattle population in the next 10 years so that it can be used as basic data to start a breeding business. The research was conducted at SL-SPR Maju Bersama, Sungai Lilin District, Musi Banyuasin Regency in October-December 2019. The material used in this study was the all population of bali cattle, totaling 330 head of the dam belonging to 219 farmers in SL-SPR Maju Bersama, Sungai Lilin District. This study was used survey methods and direct observation of the research object. The parameters analyzed were the potential of bali cattle, reproductive performance, the potential of feed resources and carrying capacity as well as the projection of the bali cattle population for the next 10 years based on 3 simulations, constant, improvement through the SPR program, and intervention of SPR with the government. Data were analyzed using descriptive analysis by presenting the test results in tabular form as well as the non-parametric Kruskal Wallis test to analyze the influence of factors that affect the reproductive performance of the dam. The projection of bali cattle population was calculated by the Microsoft Excel program. The results showed that the population of bali cattle in SL-SPR Maju Bersama was 1 277 heads. The dam as much as 72.7% came from non-groups, while the others were born and came from in the SPR group; 87.9% owned by themselves, while the others were profit sharing; 70% maintained intensively while the others maintained by semi-intensively and extensively; 58% mated by AI, while the others by natural; 24.5% were in the age range of 3-4 years and 43.0% had a BCS value of 3. The reproductive performance was obtained, age first calving 1 098 ± 12 days; calving interval 455.4 ± 8.33 days; days open 169.4 ± 8.33 and service per conception 5.37 ± 0.42. The origin and age of the dam had a significant effect on calving interval, days open and service per conception (P <0.05). Ownership status had a significant effect (P <0.05) on the age first calving. The total production of feed obtained from forages and agricultural crop residues as much as 15 646.92 tonnes of DM per year with a capacity of 6 259 AU and a capacity to increase the population of ruminants by 5 063 AU. The projection of the bali cattle population for the next 10 years with constant projections, projections with the SPR program and projections of SPR intervention with
