This study aimed to analyze the growth and productivity of male bred Ettawa goats that are fed with different animal feeds. The study was conducted for 4 months, from January to April 2016, at the village of Ranomentaa in the sub district of Toari, Kolaka regency. The used involved 12 male bred Ettawa goats, aging between 4-6 months and placed in 12 individual cages. The study used the Complete Randomized Design with 3 treatments and 4 repetitions, including Treatment 1 (P1), P2 (50% of mulberry leaves, 50% of gliricidia leaves), and P3 (100% of gliricidia leaves). Parameters under observation in the study were increase of body weight (PBB), weight of slaughtered animal, weight and percentage of carcass, weight and percentage of non-carcass. Results of the study showed that the average of PBB of P3 (26.98 g/day) was significantly different (P<0.05) from P2 (22.83 g/day) and P1 (22.42 g/day), whereas P2 and P1 were not significantly different. This was in line with the average of slaughtered animal weight from the highest to the lowest, namely P3 (13.29 kg), P2 (11.21 kg), and P1 (10.37 kg), followed by the average of carcass weight which was significantly affected (P<0.05) by the treatment. The average of carcass weight was P1 (4.17 kg), P2 (4.42 kg), and P3 (5.38 kg), whereas the average of carcass percentage had no significant different (P<0.05) due to the treatment with the range of 38.43–39.43%. Similarly, the weight and percentage of non-carcass were within the range of 50.73–55.09%. Based on the results of this study, it could be concluded that while feeding goats with gliricidia and mulberry leaves had a significant effect on the increase of body weight, weight of slaughtered animal, and weight of carcass, it had no significant effect on carcass percentage, weight of non-carcass, and percentage of carcass.Keywords: gliricidia leaves, mulberry leaves, growth and productivity of male PE goats
Estrus synchronization is one of the reproduction technology applied in the cows that aim to induce estrus of some cows to occur in the same time. In this research, all cows expressing estrus would be inseminated using sexed sperm that produced using column albumen method. Sexing sperm technology could be applied to produce the desired sex of calf. Effectivity of chilled sexed sperm to produce the desired sex of calf was evaluated in this research. Sixty three bali cows divided into 2 groups of ages (3-4 yo. and 5- 6 yo.) were used and performed synchronization using Capriglandin (PGF2a) hormone prior to application of artificial insemination with chilled sexed sperm. Variable measured were success rate of synchronization, estrus post synchronization, estrus quality, non return rate, conception rate and calving rate. The results showed that 62.90% of cows showed estrus following synchronization, estrus post synchronization occurred at 71.73 hours following synchronization, and estrus quality was 2.5%. There were 82.54% of inseminated cows was predicted to be pregnant after first insemination using chilled sexed sperm. However, only 73.02% could maintain the pregnancy up to calving. Whereas 78.26 % of newborn calf was male calf. Finally, it was concluded that PGF2a was effective to trigger estrus in bali cows, while sexed sperm still had good fertility and the sex of newborn calf was 78,26% confirmed the prediction. ABSTRAK Sinkronisasi estrus merupakan salah satu teknologi reproduksi yang diterapkan pada ternak sapi betina dengan tujuan untuk mendapatkan sejumlah ternak yang estrus secara bersamaan. Pada penelitian ini ternak yang mengalami estrus tersebut diinseminasi menggunakan spermatozoa yang telah melalui proses sexing menggunakan metode kolum albumen. Teknologi sexing spermatozoa memungkinkan untuk mengatur kelahiran anak ternak sesuai jenis kelamin yang diinginkan. Penelitian ini dilakukan untuk mengevaluasi efektivitas penggunaan semen cair hasil sexing dalam memproduksi anak sapi dengan jenis kelamin yang diinginkan. Sapi bali induk sebanyak 63 ekor yang dibagi ke dalam dua kelompok, umur 3-4 tahun dan 5-6 tahun digunakan sebagai akseptor pada penelitian ini. Sebelum inseminasi buatan (IB) dilakukan, semua sapi akseptor disinkronisasi menggunakan hormon Capriglandin (PGF2a). Variabel yang diamati adalah keberhasilan sinkronisasi, estrus pascapenyerentakan birahi, kualitas estrus, non return rate, conception rate dan calving rate. Hasil penelitian menunjukkan bahwa 62,90% sapi mengalami estrus setelah sinkronisasi dengan rataan waktu munculnya estrus 71,73 jam dan kualitas estrus 2,5. Sapi yang diprediksi bunting setelah inseminasi pertama dengan semen hasil sexing mencapai 82,54%. Jumlah sapi yang mampu mempertahankan kebuntingan hingga melahirkan hanya 73,02% dengan persentase jumlah anak sapi jantan yang dilahirkan mencapai 78,26%. Simpulan yang dapat diperoleh dari hasil penelitian ini adalah PGF2a cukup efektif merangsang munculnya estrus pada sapi bali induk dan spermatozoa hasil sexing masih mempunyai daya fertilitas yang cukup baik dengan tingkat kesesuaian jenis kelamin anak sapi yang dilahirkan mencapai 78,26%.
Penelitian ini bertujuan untuk mengetahui berapa besar konsumsi pangan asal ternak dan pengaruh faktor sosial ekonomi terhadap konsumsi pangan asal ternak di Kota Kendari. Populasi penelitian meliputi masyarakat Kota Kendari yang mengkonsumsi pangan asal ternak. Analisis data dilakukan dengan menggunakan analisis Regresi Linier Berganda yang dilanjutkan dengan uji F dan uji t. Hasil penelitian menunjukkan bahwa konsumsi pangan asal ternak adalah 63,46 gram/kapita/hari yang terdiri dari daging sapi sebesar 1,10 gram/kapita/hari, ayam sebesar 33,59 gram/kapita/hari, telur sebesar 22,09 gram/kapita/hari, dan susu 6,68 gram/kapita/hari.Hasil analisis regresi menunjukkan bahwa secara bersama-sama variabel independen memberikan pengaruh yang signifikan (P<0,01) terhadap variabel dependen dengan nilai R2 sebesar 0,79. Secara parsial, pendidikan dan tanggungan keluarga memberikan pengaruh yang signifikan (P<0,01) terhadap konsumsi pangan asal ternak. Konsumsi pangan asal ternak di Kota Kendari dipengaruhi oleh variabel pendidikan dan tanggungan keluarga sedangkan variabel umur dan pendapatan tidak menunjukkan adanya pengaruh terhadap konsumsi pangan asal ternak di Kota Kendari. Kata Kunci : Sosial ekonomi, Konsumsi, Pangan asal ternak
