Abstract

Boer Goat is one of the leading types of goat meat producers. The genetic advantages of Boer goats are fast growth, adaptability to various environmental conditions, have good meat quality in accordance with body conformation and have good reproductive traits. This study aimed 1) To determine the reproduction performance of male Boer goat based on birth weight, weight gain of body pre-weaning and weight of weaning calf produced. This research was done in CV. Burja Goat Farms located at Giripurno Kec. Bumiaji, Stone Town. Starting on May 16 to June 16, 2016.The method used in this study is a case study and direct observation in the field. Male Boer goats that were observed amounted 10 goats with a range of age between 2-4 years with ± 100-120 kg of. The observed variables were the reproduction performance of male Boer which can be seen from: 1) calf birth weight was measured using digital scale. 2) Weigh gain pre-weaning was measured weekly using digital scale until the calf weaned. 3) Weaning weight of calf was measured using hanging scales at the age of ± 77 days. The data obtained were then analyzed using descriptive by observing the population growth index and productivity of male Boer goats. The results of this study, it can be concluded that there are 3 best male categories viewed from the average birth weight of calf, they are P4 and P8 with average birth weight of calf of 4.0 kg, in terms of the average weight gain pre-weaning and calf weaning weight is P9 with the average weight gain pre weaning and average weaning weights of 28.9 kg and 20.5 kg respectively. Kambing Boer adalah salah satu jenis kambing unggul penghasil daging. Keunggulan genetik yang dimiliki kambing Boer adalah pertumbuhan cepat, mudah beradaptasi pada berbagai kondisi lingkungan, mempunyai kualitas daging yang bagus sesuai dengan konformasi tubuhnya serta mempunyai sifat reproduksi yang baik. Penelitian ini bertujuan 1) Untuk mengetahui penampilan reproduksi pejantan Boer yang didasarkan pada bobot lahir, pertambahan bobot badan prasapih dan bobot sapih cempe yang dihasilkan. Penelitian ini di laksanakan di CV. Peternakan Kambing Burja yang beralamat di Giripurno Kec. Bumiaji, Kota Batu. Mulai pada tanggal 16 Mei s/d 16 Juni 2016. Metode yang digunakan dalam penelitian ini adalah studi kasus dan pengamatan langsung di lapang. Kambing Pejantan Boer yang diamati berjumlah 10 ekor dengan kisaran umur ternak antara 2 - 4 tahun dengan berat badan ± 100-120 Kg.Variabel penelitian yang di amati yaitu penampilan reproduksi pejantan boer yang di lihat dari: 1) Bobot lahir cempe dilakukan dengan cara diukur dengan menggunakan timbangan digital. 2) Pertambahan bobot badan prasapih dilakukan dengan cara diukur setiap minggunya dengan menggunakan timbangan digital sampai cempe disapih. 3) Bobot sapih cempe diukur dengan menggunakan timbangan gantung pada saat berumur ± 77 hari. Data yang diperoleh selanjutnya dianalisis menggunakan deskriptif dengan mengamati indeks perkembangan populasi dan produktivitas ternak kambing pejantan boer. Hasil penelitian dapat disimpulkan bahwa terdapat 3 kategori pejantan terbaik ditinjau dari rataan bobot lahir cempe adalah P4 dan P8 dengan rataan bobot lahir cempe sebesar 4,0 kg, ditinjau dari rataan PBB cempe pra sapih dan bobot sapih cempe adalah P9 dengan rataan PBB cempe pra sapih dan rataan bobot sapih berurutan sebesar 28,9 kg dan 20,5 kg.

Abstract

This study aimed to calculate the profile of the productivity of Boerja goats at included: birth weight, body size growth prior to weaning and weaning weight. The research was conducted in the CV. Peternakan Kambing Boerja for 3 months, (In early May until early July 2016).The material used in this study was the parent of Boerja goat (F1 and F2) with the number of 20 goats (10 Boerja F1 and 10 Boerja F2) which had a complete recording. Based on the result, it showed that the heterosis birth weight and weaning weight of Boerja goat F1 and F2 indicated that the period of third birth increased compared to the first, second and fourth period of the birth. It was influenced by the high weight of the calf born to the third period which effected the growth size of the body prior to weaning and weaning weight. Because different birth weight would require different feeding and body size. Penelitian ini bertujuan untuk menghitung profil produktifitas ternak kambing meliputi: bobot lahir, pertumbuhan ukuran tubuh sebelum sapih, bobot sapih. Penelitian ini dilaksanakan di CV. Peternakan Kambing Boer jaselama 3 bulan, (pada awal mei sampai awal juli 2016). Materi yang digunakan dalam penelitian ini adalah induk kambing Boerja (F1 dan F2) dengan jumlah 20 ekor (10 ekor Boerja F1 dan 10 ekor Boerja F2) yang memiliki recording lengkap. Berdasarkan hasil penelitian menunjukkan bahwa heterosis bobot lahir, dan bobot sapih kambing boerja F1 dan F2 menunjukkan bahwa periode kelahiran ke ? 3 lebih meningkat di bandingkan dengan periode kelahiran 1, 2 dan 4. Hal ini dipengaruhi oleh tingginya bobot lahir anak periode ke ? 3 yang berdampak pada peningkatan perkembangan ukuran tubuh sebelum sapih dan bobot sapih. Karena bobot lahir yang berbeda akan memiliki kebutuhan pakan dan perkembangan ukuran tubuh yang berbeda.

Abstract

This study aims to determine the relationship between lactation period and milk dairy cattle production with the material used is Fries Holland (PFH) dairy cows as many as 20 heads which are lactation both 12 heads, third lactation 3 heads, and fourth lactation 5 heads. The research method is field survey with the data obtained is to follow and record the amount of milk in milking process every lactation period. With the observed variables is the amount of milk production each lactation period, age, environment, feeding and disease prevention, then the existing data were analyzed using simple linear regression analysis with SPSS program statistic version 17.0. Results of this study the average production of milk dairy cows is highest in the second lactation and decreased in the third and fourth lactation sequentially ie 11.26 liters/head/day, 10.00 liters/head/day and 8.88 liters/head/day. The lactation period (lactation 2-4) had significant effect (P

Abstract

This experiment was conducted to determine the correlation of progesterone and cortisol levels in plasma between ovulated and non-ovulated Crossbreds Ettawa does. Eight does were used in this experiment and they were divided equally into 2 groups, i.e. group I consisting of 4 normal ovulated does with the average body weight of 37.5 ± 3.109 kg and group II consisting of 4 non-ovulated does with the average body weight of 28 ± 2.160 kg as group II. The estrus cycles of all does were synchronized using intravaginal device of controlled internal drug release (CIDR) accompanied by intra-muscular injection of prostaglandin F2 (PGF2) alpha. Immediately after the onset of estrus, blood samples were collected from jugular every 3 and 6 hours for 72 hours after onset of estrus. The concentration of cortisol and progesterone in plasma was assayed by enzyme linked immunosorbent assay (ELISA). The results showed that the average concentrations of cortisol in ovulated does (90.89±26.22 ng/mL) was higher than in non-ovulated does (42.70±37.18 ng/mL). Similarly, the concentrations of progesterone in ovulated does (0.098±0.0423 ng/mL) was higher than in non-ovulated does (0.093±0.056 ng/mL). It was evident that the change in progesterone level was closely associated with the change in cortisol level in plasma.
