ABSTRACT (pdf)

The experiment was done on two couples of deer to determine digestilibities and consumption of grass and corn. Each heads of deers of 12-14 months, each couple was managed on difference model of stable (mini ranch and traditional stable) the grass was kept available to deers during the periods of observation and corn was given every two days (250 g). Description analysis and Tillman et al. formula (1984) were implemented to know the level of consumption and digestibility of feed on difference model of stable. Quantitativelly, the deers on the mini ranch were the best; the digestilibities of its constituents were 58.4% crude fibre; 58.9% organic matter and 47.7% dry matter, digestilibities on the tradisional stable were 49.2% crude fibre; 52.2% organic matter and 50.7% dry matter. Feed consumption of the deers on the mini ranch and traditional stable were 1.570 kg and 1.440 kg.

Key words: Deer, digestibility, corn, grass.

ABSTRACT (pdf)

Information of kind, nutrive value, and used of forages for horse is limited. The aim of this research was to know the kind and nutrive value of forages for horse. The research was conducted in Kecamatan Kadungora, Wanaraja, and Bl Limbangan Kabupaten Garut West Java. Analysis of nutrive value of forage was done at Laboratory of Forage Crops and Laboratory of Ruminant Nutrition and Feed Chemistry. Survey method and stratified random sampling were used in this research. Research result showed that feeding system of horse farmers based on the habit from forefathers, the mean of nutrive values from Oplismenus burmanni, Cynodon dactylon and Brachiaria mutica were good as forages. Based on botanical composition and nutrive value, development and improvement of Oplismenus burmanni, Cynodon dactylon and Brachiaria mutica were needed.

Abstract(more, pdf) 

Degradation characteristics of four grasses, three leguminous fodder species, jack leaves, coconut meal and rice bran were studied using the nylon bag procedure. Bag incubations up to 10 days were performed in the rumen of cows fed on a ration consisting of 50% wheat straw and 50% hay.

Degradation characteristics for organic matter (OM), neutral detergent fibre (NDF) and nitrogen (N) were evaluated using a two fraction model with a fixed undegradable fraction ( V) and lag time. Among the grasses, the degradable fractions (D) of OM and NDF in NB21 and guinea grass were significantly higher (P <0.05) than in the other two grasses. Guinea grass not only had the highest N content (20.3 g kg- ’ dry matter (DM) ), but also its D fraction was significantly higher (P < 0.05) than that of the other grasses. The rate of degradation (/cd) for all components studied did not differ significantly between grasses. Unlike in grass species, the D and U values obtained for OM, NDF,

and N in legumes species did not differ significantly, but the k,, values were significantly (P < 0.05) different.

Except for the long lag phase in jack leaves, which ranged from 10.4 h for NDF to 11.5 h for N, all other degradation-characteristics were significantly higher (P < 0.05) than for grasses and rice bran. The poor nutritive value of rice bran obtained from a commercial mill was reflected in the extremely high U fraction (47%, 66% and 22% for OM, NDF and N, respectively). Nevertheless, the degradation characteristics (D and kd) for N were significantly better than for grasses. Coconut meal had the highest potentially degradable fraction (D+ water soluble fraction).

Rumen degradable N content in grasses ranged from 41% (guinea) to 60% (ruzi), and in legumes from 69% (leucaena) to 79% (glyricidia). About 67% of the N present in jack leaves and rice bran was rumen degradable.

Penggunaan Feses Sebagai Pengganti Cairan Rumen Pada Teknik
In Vitro : Estimasi Kecernaan Bahan Kering dan
Bahan Organik Beberapa Jenis Rumput

PENDAHULUAN
Di beberapa negara Eropa dan Amerika telah dilakukan usaha pemanfaatan inokulan feses sebagai pengganti cairan rumen dalam mengevaluasi kecernaan pakan ternak. Berbagai usaha telah dilakukan dalam pemanfaatan feses sebagai alternatif pengganti cairan rumen. Balfe (1985) pertama kali menggunakan cairan feses sebagai pengganti cairan rumen dalam teknik Dua Langkah Tilley and Terry. Kemudian diikuti oleh Akhter (1994) dan Omed dkk (1998) menggunakan feses dalam teknik in vitro gas. baca selanjutnya pdf
