Abstract

NITROGEN RETENTION AND METABOLIZABLE ENERGY OF MULBERRY (Morus alba) FRESH LEAVES IN DIET OF BROILERS. The study was determine to evaluate the effect of Mulberry (Morus alba) fresh leaves in diet on nitrogen retention and metabolizable energy corrected for nitrogen of broilers. A total of 20 birds at age of 6 weeks old were used for 7 days of preliminary period and 3 days of data collection period using a completely randomized design with four treatments and five replications. The dietary treatment was including levels of 0, 2, 4, and 6% of fressh mulberry leaves in the diets. The variables were nitrogen retention (NR) and metabolizable energy corrected for nitrogen (AMEn). Results showed that there were significant differences (P˂0.05) among treatments for NR and highly significant differences (P˂0.01) among treatments for AMEn. Analysis of variance for NR showed that there was no significant difference between R0 (89.81%) and R1 (85.97%) of diets. Similarly, there was no significant difference between R1 (85.97), R2 (84.51%) and R3 (84.09%) of diets. The values of AMEn showed that R0 diet had significant difference with those of R1 (3517.80 Kcal/Kg), R2 (3451.73 Kcal/Kg) and R3 (3360.90 Kcal/Kg). However, between R1, R2, and R3 had no significant differences. The results suggested the experiments of mulberry fresh leaves in level up to 6% can be used as an alternatives feedstuff of broiler diet based on nitrogen retention and metabolizable energy corrected for nitrogen. Key  words: broiler, murbei leaves, nitrogen retention and metabolic energy corrected nitrogen

Abstract

ENERGYANDPROTEIN DIGESTIBILITY OF BROILER CHICKEN CONSUMING MAGGOT (HERMETIA ILLUCENS) MEAL SUBSTITUTING FISH MEAL IN THE DIETS. As an animal feed, maggot from black soldier fly (Hermetia Illucens) has high protein and fat content. Yet, little is known about the digestibility of energy and protein in the diet containing maggot. The present study was conducted to determine the effect of substitution of fish meal with maggot meal in the diets on energy and protein digestibility of broiler chicken. Twenty chicks were assingned to each dietary treatment which was replicated four times in a completely randomized design (CRD). Tretaments were formulated as follow: R0 = 100% fish meal (15% in the diet) + 0% maggot meal (0% in the diet); R1 = 75% fish meal (11,25% in the diet) + 25% maggot meal (3.75% in the diet); R2 = 50% fish meal (7.5% in the diet) + 50% maggot meal (7.5% in the diet); R3 = 25% fish meal (3.75% in the diet) + 75% maggot meal (11.25% in the diet); and R4 = 0% fish meal (0% in the diet) + 100% maggot meal (15% in the diet). Parameters measured were energy and protein digestibility. Energy and protein digestibility were calculated using the indicator (internal lignin) method. All data was submitted to the ANOVA procedure for completely randomized design. Differences were considered significantat (P< 0.05). The results showed that dry matter, energy, and protein digestibility were increased significantly (P < 0.05) compared to R0, R2, R3, and R4. No significant difference (P > 0.05)  were found among R0, R2, R3, and R4. It can be concluded that the maggot flour is best used to the level of 25% replacing fish meal or 11.25% in the ration. However, the result of this study indicate that maggot flour can be used up to 100% replace fish meal in broiler chicken rations without any negative effect on digestibility of dry matter, energy, and protein. Keywords: Fish meal, maggot (Hermetia Illucens) meal, energy and protein digestibility.

Abstract

ABSTRACT EFFECT OF SUBSTITUTION OF FISH MEAL WITH MAGGOT (Hermetia illucens) IN THE DIETS ON BROILER CHICKEN PERFORMANCE. Maggots (maggot meal) have been widely studied as a good alternative to fish meal in broiler chicken and pigs. The present study was designed to elaborate the effect of substituting fish meal with maggot (Hermetia illucens) meal in the diets on feed efficiency of broiler chicken. Eighty day old chicks (DOC) broiler chicks were placed in battery cages and were assigned to each dietary treatment (5 treatments) which was replicated four times in a completely randomized design (CRD) arrangement anddatawere all submitted to the ANOVA procedure. Differences were considered significant at P< 0.05.  Diets were formulated to meet or exceed starter and finisher broiler requirements as recommended by NRC (1994). Treatment diets were formulated as follow: R0 =  100.0% fish meal (15.0% in the diet) + 0% maggot meal (0% in the diet); R1 =  75% fish meal (11.25% in the diet) + 25.0% maggot meal (3.75% in the diet); R2 = 50.0% fish meal (7.5% in the diet) + 50.0% maggot meal (7.5% in the diet); R3 = 25.0% fish meal (3.75% in the diet) + 75.0% maggot meal (11.25% in the diet); and R4 = 0% fish meal (0% in the diet) +100.0% maggot meal (15.0% in the diet). Parameters measured were: feed consumption, daily gain, and feed efficiency ratio. Research results showed that feed consumption, daily gain, and feed efficiency ratio of starter and finisher broiler chicks in the present study were significantly decreased as maggot meal substituted fish meal at the level of 100% or 15.0% in the diet (R4). It can be concluded that maggot (Hermetia illucens) mealcould replace fish meal up to 75.0% or 11,25% in the diet without any negative effects on feed efficiency ratio of broiler chicken. Keywords: Fish meal, Maggot (Hermetia illucens) meal, Broiler chicken, Feed efficiency ratio

Abstract

ANIMAL WASTE PRODUCT MANAGEMENT FOR PREVENTION OF ENVIRONMENTAL POLLUTION IN KOTAMOBAGU CITY. The animal wastes from animal farm affect the environmental condition of human settlement, when it was not well managed. The objectives of this study was to evaluate either levels of knowledge, attitude and technical skill had correlated directly or not with their motivation activity in preventing environmental pollution of animal wastes around Kotamobagu city. Variables in this study were referring on the farmer’s standard knowledge (X1), attitude (X2), technical skill (X3) and motivation activity in preventing environmental pollution of animal wastes (Y) around Kotamobagu city using the functions of linear multiple regression, Yi = b0 + b1X1 + b2X2 + b3X3 + ei; where Yi was the-i observation of farmer’s  motivation activity in preventing environmental pollution of animal wastes; b0 was intercept; b1, b2 and b3 were regression coefficients, X1 was farmer’s knowledge, X2 farmer’s attitude, X3 was farmer’s technical skill in preventing environmental pollution of animal wastes; and e1 was random error. Results of this study showed that knowledge level (X1), attitude (X2) and technical skill (X3) of farmers could be the important factors affecting farmer’s motivation activity in preventing environmental pollution of animal wastes (Y) in Kotamobagu city areas.  The equation of multiple regression model was found, Y = 1.468 + 0.784 X1 + 0.218 X2 + 0.004 X3. The determination coefficient (R2) of 0.81 in this model indicated that 81 percents of the variation of independent variables (X1, X2, and X3) used in the model were able to affect the variation of the dependent variable (Y). The rest of 19 percents in the model were caused by the other unknown factors. The average score values of knowledge level (X1=87.23), attitude (X2=93.37) and technical skill (X3=88.40) and farmer’s motivation activity (Y=90.60) in preventing environmental pollution of animal wastes (poultry and pig) in Kotamobagu city areas were still below the score median values (X1=93; X2=100; X3=100; Y=93) of those variables. This condition suggested that extension activities related to the prevention of environmental pollution of animal wastes in Kotamobagu city areas were still needed to be conducted, mainly to the farmers with low scores in knowledge, attitude, technical skill and motivation activity in preventing environmental pollution of animal wastes. Key words: Animal waste product, prevention of environmental pollution, Kotamobagu city.
