LOCAL BEEF CATTLE DEVELOPMENT STRATEGY Agustinus Lomboan*1), Femi H. Elly1), Tilly F.D. Lumy1) and Derek Polakitan2) SAM RATULANGI UNIVERSITY Abstract Related to food availability, one of the livestock commodities that was very supportive was local beef cattle developed in Minahasa Regency. Local beef cattle in this case were developed traditionally. Traditional maintenance systems were generally carried out on a small scale. The problem was how far the local beef cattle development strategy was in the area. Development strategies were needed to encourage conventional beef cattle farming. The purpose of this study was to analyze the local beef cattle development strategy in Minahasa Regency. The research method was a survey with a purposive sampling method. Respondents were selected using simple random sampling, totaling 60 farmers. The data analysis used was descriptive with a SWOT analysis approach. The results showed that Minahasa Regency had prospects and opportunities because it was a local beef cattle base area. This was supported by the potential carrying capacity of the land and the RC ratio value was greater than one. The challenge was that land use and the introduction of IB technology had not been optimal. The conclusion was that the local beef cattle development strategy was an aggressive strategy needed to support beef cattle productivity.

FACTORS INFLUENCING THE LABOUR PRODUCTIVITY IN SMALLHOLDER DAIRY FARMS (CASE STUDY IN KEDIRI REGENCY, EAST JAVA, INDONESIA) Eko Nugroho, Zia Ul Rahman Fithron, and Khusnul Fajriyah Faculty of Animal Science, Universitas Brawijaya Abstract The majority of small-scale dairy industry in South-east Asia depends on farmers using their own family labour in operating their dairy activities. As dairy farming is a highly labour intensive production activity, its success is substantially challenged by smallholder farmers^ labour productivity. Our objective is to assess the factors affecting labour productivity in small-scale dairy farms in East Java, Indonesia. We collected 100 surveys from dairy farmers in Kediri regency from November to December 2023. Using ordinary least squares regression model, we examined factors affecting the labour productivity. Our findings suggest that labour productivity increases with increased level of education. Age, family size, number of cattle owned by a household, and non-farm employment correlated negatively with labour productivity. Increasing farmers^ knowledge and skills about good dairy farming practices is needed to improve the labour productivity, for instance, through intensive extension service.

Currently, Indonesia is the largest global producer and exporter of EBNs. However, due to high nitrite levels, China has banned the import of EBNs from Indonesia and Malaysia. Nitrite forms in EBNs naturally, driven by fluctuations in nitrogen levels within Swiftlet farmhouses. Since nitrite leads to the formation of methemoglobin, which hinders oxygen transport, it can be toxic and harmful. Therefore, reducing nitrite in EBNs is crucial. This study investigates the effectiveness of P. pentosaceus and L. plantarum in lowering nitrite levels in EBNs. The results indicate that applying L. plantarum and P. pentosaceus significantly (p<0.05) reduced nitrite levels in EBNs. Spraying EBNs with 1.2 x 108 CFU/g of L. plantarum and P. pentosaceus decreased nitrite by 84.65% (1.65 +- 0.17 ppm) after 1 h, 82% (1.94 +- 0.02 ppm) after 3 h, and 78% (2.27 +- 0.2 ppm) after 6 h. These findings demonstrate that nitrite levels in EBNs can be effectively reduced using L. plantarum and P. pentosaceus. The method is cost-effective, safe, easy to implement, leaves no residue, and yields excellent results, making it suitable for large-scale nitrite processing in EBN factories.

Effects of pre-hatch thermal programming on hatching period and chick quality of crossbred chickens Faizal Andri1*, Edhy Sudjarwo1, Filoza Marwi1, and Ani Atul Arif1 1Faculty of Animal Science, Universitas Brawijaya, Malang 65145, Indonesia *Corresponding author: f.andri[at]ub.ac.id Abstract Incubation conditions play a crucial role in determining hatchery performances. This study evaluated the effects of pre-hatch thermal programming on the hatching duration and chick quality of crossbred chickens. A total of 200 fertile eggs were randomly and evenly distributed across four treatment groups, each with five replicates (10 eggs/replicate). T0 served as the control with standard incubation at 37.5 degree C and 55% RH throughout the entire hatching period. T1, T2, and T3 were pre-hatch thermal programming by applying standard incubation but with increasing incubation condition at 39.5 degree C and 65% RH at 10-18 embryonic days for 2 h/day, 4 hours/day, and 6 hours/day, respectively. Data were analyzed using one-way analysis of variance, with post-hoc Duncan test. The results showed that pre-hatch thermal programming had a significant impact (P<0.05) on both the hatching period and chick quality of crossbred chickens. It could be concluded that pre-hatch thermal programming is substantial to support hatching period and chick quality of crossbred chickens.

Purification of Quality Biogas with Different Types of Animal Waste by Condensation and Multilevel Adsorbtion Method Arina Manasikana1* , Osfar Sjofjan1, and Sri Minarti2 1*Doctoral Program, Faculty of Animal Science, Universitas Brawijaya, Malang 65145, Indonesia 1,2Lecturer, Faculty of Animal Science, Universitas Brawijaya, Malang 65145, Indonesia Abstract Biogas is renewable energy that can be seen from technical, economic, and social aspects which can be used to supply energy that comes from fossil fuels. Biogas contains methane (CH4) and carbon dioxide (CO2) as well as several other gasses, namely hydrogen sulfide (H2S), ammonia (NH3), hydrogen (H2) and nitrogen (N). Biogas can be made from livestock waste such as animal manure by ruminants, pseudoruminants and non-ruminants. Therefore, this study aims to compare the quality biogas before and after purification from different types of animal manure by condensation and multilevel adsorption method. Types of animal manure used in the research by cow dung, rabbit manure, broiler manure, and mix manure. Then all treatments will be purified with condensation and multilevel adsorption methods with 5 different adsorbents (roof tile waste (RW), CaO (CO), activated carbon (AC), iron powder (IP), and zeolite (Z). The methods were the preparation of feedstock, purification tools, biogas production. The parameters measured were biogas content before and after purification. The research design used was a Completely Randomized Design (CRD). The results obtained were tasted by One Way ANOVA followed by DMRT Test with a confidence 95% (&#945-=0.050). Furthermore, the effect of different types of animal manure on quality biogas is the highest CH4, lowest CO2 and lowest N2O content resulting from purification using A3T6 for CH4- CO2 and A3T0 for N2O.

PRODUCTION PERFORMANCE OF GESTATING DOES OF ORNAMENTAL RABBITS, CASE STUDY: SMALLHOLDER RABBIT FARMS IN BUMIAJI DISTRICT Poppy Satya Puspita1* and Sri Minarti1 1Faculty of Animal Science, Universitas Brawijaya, Malang 65145, Indonesia Abstract This study aimed to determine the production performance of ornamental rabbits during the pregnant period in rabbit farms in Bumiaji District, Batu City. The method used in this study was survey and direct interview with farmers of ornamental rabbits (Dutch, Holland Lop, and Netherland Dwarf). Primary and secondary data were collected by observation. Research variables included initial body weight, body weight gain during pregnancy, and birth weight of the offspring. Data were analyzed using analysis of variance and if there were differences between treatments, Duncan^s test was conducted. The results showed no difference in initial body weight and weekly body weight gain during the gestation period, but there was a significant difference (P> 0.05) in the birth weight of the offspring of the three different strains. The conclusion of this study is that the production performance of ornamental rabbits during the gestation period is Dutch strain.
