Abstract

This study aimed to explore the socio-economic benefits of Jabres cattle as potential local livestock in two agro ecological zones, lowlands and middle zone in Bantarkawung Sub-District, Brebes, Central Java. The data were collected by Participatory Rural Appraisal (PRA) method, which is an approach to families or individuals to analyze the reality of their living conditions. This study involved 60 farmers which selected by purposive sampling based on three considerations. The analytical model used to test differences is the analysis of independent T-test. The result showed that the farmers in the middle zone are younger and most of their cattle keeping motivation are for livelihood. Meanwhile, the farmers in the low lands are older and most of their cattle keeping motivation is for saving only (2.90±0.31). This condition caused the socio-economic benefit difference between those locations where the value of net production (185±27 kg/y), added value (IDR 4.900.000±1.204.000), and total benefits (IDR 9.289.000±1.542.000) were higher in the medium land than in the lowlands. Based on these reasons, it can be concluded that middle zone farmers have more possibility to sustain their farm than those of lowlands farmers.

Abstract

Crossing between cattle breeds is the one way to improve the genetic quality of cattle. Controlling crosses using genetic markers will speed up the process. The IGFBP-3 gene is a potential marker of selection due to its role in regulating growth and metabolism in cattle. The aim of this study was to determine the effect of genotype on birth size and birth weight using IBFBP-3 gene marker. A total of 32 cattle consisted of 10 Brahman Cross cattle, 14 cattle results of Brahman Cross cow crosses with Belgian Blue bull, and 8 cattle results of Brahman Cross cow crosses with Wagyu bull. Sequences of 563 bp, including the part intron 2, exon 3, and the part intron 3. Genotyping was done by sequencing method and PCR-RFLP method with the restriction enzyme PvuII. An SNP was identified at location g 3,930 (G>A). Two genotypes were observed, namely GA and GG. The genotype did not affect the performance of birth (body weight, body length, height at withers, heart girth) of the research sample. Birth traits are influenced by the cattle breed, it can be seen that Brahman Cross cattle have a body length that is bigger than the other crossbred.

Abstract

This study aimed to estimate natural increase (NI), net replacement rate (NRR), output, and population dynamics of Aceh cattle at Livestock Breeding and Forage Center in Indrapuri, Aceh province. Data of population structure, mortality, birth rate, the number of animals entering the herd, and the number of animals released from the herd during 2019were used for determining NIandNRR, and it isusedfor estimation of output. Population structure data (2015-2019) were used to estimate the population dynamics. The results showed that NI was 19.08% (medium category). The availability of replacement stock exceeded the need for replacement (140.08% for male and 73.33% for female); the NRR was 240.08% (male) and 173.33% (female). The output of Aceh cattle was 3.92% (culled male), 5.58% (culled female); the remaining replacement stocks were 5.49% (male) and 4.09% (female) of the total population. The population of Aceh cattle from 2020 to 2024 was expected to increase by 6.02% (65 heads) on average. In conclusion, that BPTU-HPT Indrapuri can be categorized as a beef cattle producing region, but still need efforts to increase natural increase by increasing birth rate minimum 32.77% and reducing mortality maximum 3.0%, in combination with better management systems.
