Effects of Different Feeding Frequency of Faba Beans on Rumen Degradation Characteristics of Oaten Hay in the Rumen of Sheep
No full textPenelitian telah dilaksanakan dengan tujuan untuk mengetahui pengaruh frekeuensi pemberian yang berbeda dari bijian faba terhadap karakteristik degradasi hijauan oat pada rumen ternak domba. Empat ekor ternak domba jantan kastrasi yang telah dilengkapi dengan kanula pada rumen, dengan bobot badan rata-rata 85 ± 5,5 kg, digunakan dalam percobaan ini. Kombinasi (85:15%) antara hijauan oat dan alfalfa digunakan sebagai ransum basal selama studi. Bijian faba digunakan sebagai pakan suplemen diberikan pada level 0,5% dari bobot hidup. Penelitian dilaksanakan berdasarkan pola rancangan bujur sangkar latin 4 x 4. Setiap periode berlangsung selama 20 hari. Pada masing-masing periode, setiap ternak mendapatkan salah satu dari 4 macam ransum perlakuan, yakni T0 = ransum basal tanpa suplemen, T1= T0 + FB yang diberikan sekali dalam sehari pada pagi hari, T2 = T0 + FB yang pemberiannya dibagi dua dan diberikan pada pagi dan sore hari, dan T3 = T0 + FB yang pemberiannya dibagi atas 8 bagian yang sama dan diberikan setiap tiga jam. Hasil analisis statistik memperlihatkan bahwa suplementasi dengan bijian faba meningkatkan (P0,05) terhadap pH rumen, dengan rataan 6,36; 6,05; 6,15; dan 6,10 untuk masing-masing perlakuan T0, T1, T2, dan T3. Begitupula, pemberian suplemen bijian faba tidak berpengaruh nyata (P>0,05) terhadap karakteristik degradasi hijauan oat dalam rumen ternak domba. Dapat disimpulkan bahwa suplemen bijian faba dapat meningkatkan kadar NH3 dan VFA dalam rumen, tetapi tidak mengubah pH rumen dan karakteristik degradasi rumen dari hijauan oat.

The Effects of Superovulation Prior to Mating and Zinc Supplementation on Milk Yields in Etawah-Grade Does
No full textThirty six Etawah-grade does (BW ranged from 20.4 to 44.2 kg and age ranged from 2.5 to 7 years) were used to study the effects of superovulation prior to mating and zinc supplementation on milk yields. The experimental does were assigned into a randomized block design with a 2 x 3 factorial arrangement. The first factor was PMSG (pregnant mare serum gonadotrophin) injection with 2 levels (0 IU/kg BW [nonsuperovulation–NSO] and 15 IU/kg BW [Superovulation–SO]). The second factor was zinc concentration in the diet with 3 levels (40 mg/kg DM [Z-40], 60 mg/kg DM [Z-60], and 80 mg/kg DM [Z-80]). Intravaginal sponge (60 mg medroxyprogesterone acetate) was applied for 14 days to synchronize estrus cycle. Twenty four hours prior to sponge removal, PMSG was injected to stimulate superovulation. After sponge removal, 5 experimental does were mixed with 1 buck for natural mating. During pregnancy the experimental does were fed and raised in  individual stables. Udder volume was measured every other week from weeks 12 to 21 of pregnancy. During lactation (one week to 5 months post partum) kids were separated from the does, and  milk was harvested by hand milking. Milk samples were taken every other week for determination of milk quality. The results indicated that superovulation increased udder differential growth by 80% (822.85 vs 1481.25 cm3/head), milk yield by 32% (567.14 vs 746.52 g/head/day). Zinc concentration increased udder differential growth and milk yield. Milk productions for does receiving 40, 60 and 80 mg/kg DM were 565.68, 737.88 and 666.92 g/day, respectively.It was concluded that superovulation and zinc supplementation increased milk yield in Etawah Grade does.

Factors Analyses of Effecting to Milk Production and Economic Efficiency of Dairy Goat Agribisness In Kaligesing District of Purworejo Region
No full textA survey in the agribusiness of dairy goat smallholder had been conducted in Kaligesing district of Purworejo region at 13 rd September up to 7th November 2001. The survey studied the factors effecting the milk yield, in how the factors influence economically. Forty eight respondents (dairy goat smallholders) were used in this study and interview method was applied for collecting data. The variables were observed; lactation goat, man power, garage, and concentrate ration. Cobb-Douglass method was applied for analyzing the data. To know the economic efficiency of the agribusiness was approached by the ratio between the Marginal Product Value an input cost. From the data analysis it could be in formatted that the numbers of lactating goat and the numbers of lactating goat and the numbers of concentrate were significant influence on the milk yield, white the man power and the forage were not significant influence. For the numbers of lactating goat and concentrate, economically the efficiency was not yet reached, so the use of the factors were ought to be increased up to an appoint limited. On the other hand the man power and forage was not efficient, so the use of the factors need to be descreased.

Characteristics of Body Dimension and Male Reproduction on Groups of Sheep Population at Pandeglang and Garut Regencies
No full textThe objective of the research was to characterise body and testes dimension of sheep, the optimal age of scrotal development for selection, and the correlation between body and scrotal measurements as a base for selection. The sheep surveyed were those owned by farmers at Pandeglang and Garut regencies that have been received grants from various government projects (Banpres, Bansos, Bangub, APBD, APBN). Pandeglang area was predominated by local sheep and crosbred between local and Garut sheep. Garut area was predominated by Garut sheep and fighter sheep. Variables observed consisted of body weight, height at withers, scrotal circumference and scrotal length. Data were analysed using one-way analysis of variance continued with Duncan’s multiple range test by mean of SAS software release 6.04. Results showed that fighter sheep have higher body and scrotal dimensions than other breeds. Optimum level of development of scrotal for selection was achieved when the sheep aged one year. Only scrotal circumference and length could be used for assessing sheep fertility, whereas body measurement and scrotal dimensions has low correlation.
