Abstract

Does reproduction performance could be expressed by her ability to give birth and to give milk to their kids during the pre-weaning period. This study was aimed to evaluate the reproductive performance of Boer, Kacang and Boerka does; and was carried out for two years at Research Institute for Goat Production, Sungei Putih. The materials used were goats owned by the institute. The parameters observed were: litter size, parity of does, preweaning mortality, kidding interval and sex ratio of kids. The rate of reproduction of the does was estimated using Amir and Knipscheer methods and were statistically analyzed using General linear model. Results showed that litter size and kidding interval of Boer goats were higher (P < 0.05) then that of Kacang goats, while the Boerka goats was in between. The mortality at preweaning of Boer goats was lower (P < 0.05) then that of Kacang goats, while the Boerka goats was in between. The percentage of kid sex ratio of three breeds were fluctuated. Parity of does had significant effect on all reproduction traits (P < 0.05) except for sex ratio of kids. The does reproduction was smallest at the first parity, and increased with the increase of parity from one to four, and then decreased in subsequent parities. The highest does reproduction rate was found in the Boerka (1.82), followed by Boer (1.80) and Kacang (1.80). It is concluded that the reproductive performance of the three breed female goat was relatively the same. Key Words: Performance, Reproductive, Boer, Kacang

Abstract

ABSTRACT. Inseminasi buatan merupakan salah satu bioteknologi dalam bidang reproduksi ternak yang memungkinkan manusia mengawinkan ternak betina tanpa perlu seekor pejantan. Penelitian bertujuan mengetahui faktor-faktor yang memengaruhi keberhasilan inseminasi buatan pada sapi yang dipelihara secara semi intensif telah dilakukan mulai bulan Juli sampai Oktober 2022 di Kabupaten Deli Serdang. Penelitian dilakukan dengan metode survey, menggunakan data primer dan data sekunder. Data primer diperoleh melalui wawancara langsung kepada peternak menggunakan kuesioner yang terstruktur, data sekunder diperoleh dari dinas terkait. Varibel yang diamati meliputi : angka kebuntingan, jumlah sapi betina, pengetahuan peternak dalam mendeteksi berahi, skor kondisi tubuh, jarak lokasi dan ketepatan waktu IB. Data yang diperoleh dianalisis menggunakan uji regresi linear berganda. Hasil penelitian menunjukkan bahwa R2 =65,3 yang artinya sebesar 65,3% variabel yang diamati memengaruhi angka kebuntingan sedangkan 34,7% dipengaruhi oleh faktor lain. Jumlah sapi betina di tiap lokasi penelitian secara signifikan (P0,05) memengaruhi keberhasilan inseminasi buatan. Berdasarkan uraian tersebut maka dapat disimpulkan bahwa secara nyata jumlah sapi betina memengaruhi keberhasilan IB dan secara simultan bersama variabel pengetahuan peternak dalam mendeteksi berahi, ketepatan waktu IB, jarak lokasi peternak dengan petugas IB serta BCS sebesar 65,3% memengaruhi keberhasilan IB di Kabupaten Deli Serdang.(Analysis of successful factors for artificial insemination cattle in the reproduction optimization program in Deli Serdang Regency, North Sumatera)ABSTRAK. Artificial Insemination is one of the biotechnology in field of livestock reproduction that allows humans to inbreed female livestock without needed of male cattle. The method of this research was survey method, using primary data and secondary data. Primary data was obtained by distributing questionnaires and interviews directly to farmers as additional information, while secondary data obtained from inseminators related to the results of artificial insemination in the Deli Serdang District. The questionnaire used included questions about cattle characteristics such as pregnancy status, knowledge of breeders in detecting heat, body condition scores, number of cows, location distance and breeder profiles with 95 respondent breeders from three districts. Data were analyzed using multiple linear regression tests. The results showed that as many as 5 variables were observed simultaneously only 65.3% affected the pregnancy rate while 34.7% were influenced by other factors. The conclusion of the study is that the factors that influence the success of artificial insemination in cattle in Deli Serdang Regency are the number of cows in the sub-districts studied.
