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.

Abstract

The experiment was conducted to investigate the effects of varios fermented mother liquor (FML) levels supplemented into cassava meal as ration for growing local female sheep.Parameterr measured involved feed consumption and average daily gains (ADG).The Animal feed composedof a basal ration of elephant grass supplemented with FML at levels of 0.0, 7.5, 15.0 dan 22.5 g, respestively. The ration was given individually amounting 240 g cassava meal and 1250 g elephant grass per animal.The results indicated that 15.0 g and 22.5 g FML supplementation increased cassava meal consumption (P<0.05) and ADG, decreased FCR and feed cost. The optimum ADG was 36.46 g that was obtained by the 22.5 g FML supplementation.

Abstract

The research was done to rest: a) If anaerob fermentation could destroy cyanogenic glucoside, b) If silage of cassava plant, which was high in nutritive value and low cyanide content, was influenced by the proportion of roots, stems and leaves in the silage. The material used in this research was Pengkang variety, a bitter cassava plant, a nine months old. The treatments were 10 different silage of ration for silage with different periods of fermentations, i.e: 0, 7, 21 and 35 days. The split plot design and polynomial orthogonal test were applied for the statistical analysis.The result of this experiment showed that the decreasing in cyanide acid content was affected by the fermentation period (p<0.01), the proportion of cassava plant biomass (p<0.01) as well as by the interaction between the fermentation period and the proportion of cassava plant biomass (p<0.01). The best silage was obtained from the cassava plant biomass that consisted of 25% roots, 25% stems and 50% leaves that was fermented for 21 days. This silage had the lowest cyanide acid content, and the highest crude protein, crude fiber, TDN content and as well as the highest digestibility for Ruminants.

Abstract

The effect of inclusion of an anti coccidial drug (lasalocid) and supplementation of growth promotant (bayonox) in broiler chicken diets were assessed by a feeding trial. Three levels of lasalocid (60,75 and 90 ppm) and one level of bayonox (10 ppm) were included in the diets. The birds were fed ad libitum for a period of 42 days. There was significant effect of lasalocid supplemention on either growth rate, food consumption or food conversion ratio. However, growth rate tended to increase on 60 ppm lasalocid supplementation. The addition of bayonox significantly (P<0.05) increased growth rate, whilst there were no significant interaction effect of supplementation of lasalocid and bayonox on growth rate, food consumption and food conversion ratio.

Abstract

The aim of the experiment was to study the effects of protein levels in the diets on body weight gain, final body weight, feed consumption, feed conversion and to determine the income over feed and chick cost of the chickens. The experiment used 180 day old broiler chicks and it was conducted at the Department of Animal Production, Faculty of Animal Husbandry, Bogor Agricultural University (started November 2, 1984 until December 27, 1984). Analyses of variance were conducted for completely randomize design with 3 treatments and 6 replications. Significant differences in body weight gain, final body weight, feed consumption and feed conversion between diet of 23% protein and of 18% protein were apparent. The diet of 23% protein had the highest income over feed and chick cost.
