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

The research objectives was to analyze the farmer’s decision in selecting breed of bull frozen semen for Artificial Insemination (AI) and determine the factors influencing the decision. There were five bull frozen semen options which simulated in this research, such as Simmental, Limousine, Ongole Grade (Peranakan Ongole / PO), Brahman, and other option. ”Other” option was used if the farmer did not recognize what breed of frozen semen was inseminated to their cow. Farmers must choose only one option of bull frozen semen that suitable for their cow. This study was conducted by collecting data using questionaire from 400 beef cattle’s farmers in Central Java Province and Yogyakarta Province. Respondents were selected by multistage random sampling technique. Descriptive statistical analysis and multinomial logistic regression analysis was used in this study The results revealed that 42% of farmers were more interested in inseminating their cows with bull semen from Simmental, and 30.75% of farmers were more interested in Limousin. Other variables such as family member, AI’s cost, land ownership, cow breed which lastly being inseminated, geographical factor, and farmer’s knowledge about the inseminatorswere variables that determine farmer’s decision process.
