Abstract

In tropics climate, growth is so fast that many grasses don't maintain mineral status satisfactory for ruminants nutrition. Several publications showed that plant grown under reduced light intensity contain higher mineral than the open condition. Improving forage quality through nitrogen fertilizer has been well documented since many years ago. To get information the influence of shade and nitrogen fertilizer on the chemical composition of Brachiaria, decumbens, stapf, a split-plot experiment with shade intensity (0, 30 and 60%) as main plot and nitrogen fertilizer (0, 75 and 150 kg/ha) as sub plot was conducted on latosol soil at IPB experimental farm, Tajur-Bogor from April to August 1986.The results showed that nitrogen fertilizer affected N, P and K content significantly. There was interaction between shade and nitrogen in relation to plant N and P content. This meant that the response of the grass to the nitrogen fertilizer differed at various level of shade intensity. Application of the nitrogen fertilizer at 60% shade intensity did not affect the increase of Plant N content. Nitrogen fertilizer increased plant P content significantly at 60% shade intensity, but did not at 0 and 30%. The increased of shade intensity, raised the plant mineral content.

Abstract

Nitrogen Fixation by legume. In developing tropic countries, application of nitrogen fertilizer into pasture to improve the quality of herbage is not yet practiced widely due to the high of fertilizer cost and the low of animal farmers income. The use of legume in the form of mixed cropping in a pasture to improve the quality of pasture has been practiced in Australia and New Zealand since 50 years ago, and it still interested one to be studied and developed at present and the future. One of determinant factors as a key of the succesfull of mixed cropping in a pasture is the capability is not only depend on the kind of plant, but also influenced by many factors such as mineral nutrition, soil acidity, disease and insect, the potential of symbiosis and the adaptability of both the rhizobium and legume to soil and climate.

Abstract

Modification of forage micro climate and its influence on the total sugar and crude fibre content of herbage. In order to obtain information the influence of shading intensity and nitrogen application on the total sugar and crude fibre content of the herbage, a split-plot experiment was conducted at IPB experimental farm, at tajur from April to august, 1986. The result showed that shading did not affect the total sugar content in the first cutting and the crude fibre content in the first and second cuttings, but affected the total sugar content of the herbage at the second cutting.Nitrogen did not affect both the total sugar and crude fibre content of the herbage. However, there is interaction between shading and nitrogen on the crude fibre content at the second cutting; At 30% intensity, the higher the nitrogen applied the lower the crude fibre content of the herbage.

Abstract

In general, tropical grasses have low crude protein, Ca and P. For feeding the growing ruminant supplementation is needed. Urea molasses block (UMB) was used in this experiment. Sixteen male goats of about six months of age and an initial weight 13.17 + 1.64 kg were assigned in Fully Randomized Design with four replications. Each goat was kept in an individual cage. The feeding regimes were : RO = native grass only, R1=native grass + UMB (3% w/w urea), R2=native grass + UMB (6% urea), R3=native grass + UMB (9% urea). Feeding and drinking were given ad libitum. Data measurement included : dry matter, organic matter, crude protein comsumption and weight gain. The results of this experiment showed that the UMB supplementation increased dry matter, organic matter, crude protein consumption per metabolic body weight (P<0,05). Daily gain of RO, R1, R2 and R3 were 20.54, 39.88, 36.16 and 39.28 g/day/head respectively, however there were not significantly different among R1, R2 and R3 (P>0.05). Ration with UMB supplementation (3% urea) gave the most promising result.

Abstract

The purpose of this experiment were to study the optimal level of zinc in the form of zinc carbonate in the high fiber diet provided by rice bran, and to study the zinc status as well as the performance of laying hens. one control and 9 treatment groups of hisex brown laying hens, 80 in all, were fed diets with 25,50, or 75% rice bran supplemented with 25, 125, or 225 ppm zinc as zinc carbonate.Rice bran diets were isonitrogenous and isocaloric by virtue of varying levels of corn, fish meal, soybean meal and coconut oil. The experiment started at 20 weeks of age and continued 10 months. All rice bran diets produced significantly more income over feed cost than did the cornsoybean meal control. Diets with 25 or 50% rice bran and 125 ppm zinc did not differ significantly from the control in hen-day egg production. Adding 125 ppm zinc to 25 or 50% rice bran gave higher concentration in whole blood and erythrocytes than did addition of 25 ppm. The supplementation of 125 ppm zinc in 25 or 50% rice bran gave the highest zinc availability in the body. The 75% rice bran diet decreased avaibility of added zinc. Data on zinc status were obtained from randomly selected hens given labeled zinc chloride.

Abstract

The objective of this study was to develop a feeding strategy for muscovy ducks utilizing fibrous feeds for potential integration with fish culture in rainfed area of Northeast Thailand. An experiment was designed to study the effect of four different feeding strategies based on plane of nutrition of the starter and grower diets for a 12 week growing period. Strategy 1 (S1) was to feed duck with high nutritional plane of starter diet for 6 weeks, subsequently followed by high nutritional plane of grower diet for another 6 weeks. S2 and S3 were high nutritional plane of starter diets for 6 and 3 weeks, and subsequently followed by low nutritional plane of grower diet for 6 dan 9 weeks, respectively. S4 was low nutritional plane of starter diets for 6 weeks and subsequently followed by low nutritional plane of grower diet for another 6 weeks. Muscovy ducks were able to utilize efficiently a fibrous diets with low protein and energy. It is necessary to feed a high plane of nutrition for 3 weeks of a duck's starter period prior to feeding fibrous diet in order to attain good growth.

Abstract

Napier grass, either as sole forage or in a 50:50 combination with sugarcane tops was evaluated and compared with corn silage in growing dairy bulls. Twenty one bulls, 14.0 0.81 month of age, averaging 377  30kg in weight, were divided into weight groups. They were then fed with isocaloric and isonitrogenous diets containing either 50% corn silage, 35% Napier grass or 35% Napier grass + sugarcane tops gained 0.930 kg daily. This was significantly lower (P<0.05) than those on corn silage (1.0290 kg) or Napier grass (0.973 kg). They also consumed less dry matter (9.200 vs 9.886 and 9.929 kg) suggesting that the lower growth performance mainly due the lower palatability of the sugarcane diet. However, partial substitution of Napier grass with sugarcane tops reduced feed/gain (Rp. 1.283.02 vs Rp. 1.075.61). Eventhough corn silage was expensive (Rp. 42.--/kg vs Rp. 18.--/kg Napier grass and Rp. 14.--/kg sugarcane tops), feed cost/gain of the corn silage diet was still the cheapest (Rp. 959.24).

Abstract

Alkalinity of saturated solutions of some ashes were compared with that of 5% NaOH(pH=13.0)and 25% limestone (pH=12.2).The pH of the ash solution made of 17 % palm cluster was 11.5, that of 25% palm fibre was 10.7, that of 10% rice hulls was 7.9, and that of 10% sugarcane by product was 6.4. The solutions were then sprayed on sugarcane tops, sugarcane bagasse, palm fiber, cocoa seed coat, cocoa shell, rice straw, and Napier grass at a dose of 0.05 or 1.0 ml/kg dry matter. Effectiveness of the solutions in improving the in vitro digestibility was close correlated with pH. The 5% NaOH appeared to be the most effective in improving the in vitro digestibility, followed by limestone and then palm fiber. The most prominent changed in digestibility was occured in low quality roghages such as palm fiber, rice straw, and sugarcane bagasse. The 0.5 ml/g of the 5% NaOH solution increased the in vitro dry matter digestibility (IVDMD) of palm fiber by 45.24% and of the in vitro organic matter digestibility (IVOMD) by 48.49%. The treated roughages were then mixed into isonitrogenous (crude protein 13 - 14 %) and isolaric (gross energy 3.5 - 3.9 Mcal/kg) rations. Rate of disappearance of dry matter and organic matter of the tested rations were faster than that of the commercial concentrate-Napier grass diet. The 5% NaOH solutions was the most effective in increasing the rate of disapearances. It was concluded that the effectiveness of the ash solutions as alkali sources in improving digestibility of low quality roughages was limited by their low alkalinity.

Abstract

Some of feed factories in Indonesia produce their uncompleted ration, called concentrates, that should be mixed with some corn and rice bran to make a complete ration. A combination of 60% of corn and 40% of the concentrate in starter diet and of 60% corn, 10% of rice bran and 30% of the concentrate in finisher diet were recomended.An experiment had been conducted to study the possibility of cassava meal (peeled or unpleeled) and rice bran mixed and also with or without methionine supplementation to substitute corn in broiler diet. A combination of one third of cassava meal and two third of rice bran had similar nitrogen content with 60% of corn. One hundred day old chicks (D.O.C.) strain Arbor Acres-CP 707 divided into 20 groups. Five treatments : Ro (recomended feedmill ration), R1 (using peeled cassava meal and rice bran mixed), R2 (using unpleeled cassava meal and rice bran mixed), R1+M (R1+0.2% methionine), R2+M(R2+0.2% methionine) were used.The experiment indicated that R1 gave the best result in body weight gain and feed consumption expect for feed conversion. In the study the methionine supplementation did not improve performances. The income over feed and chick cost (IOFC) of the broiler ration contained unpeeled cassava meal and rice brand mixed was higher than that control (R0). This result is economically important for broiler farmers.
