Abstract

EFFECT OF SUBSTITUTION OF FISH MEAL WITH MAGGOT (Hermetia Illucens) MEAL ON CALCIUM (Ca) AND PHOSPHORUS (P) DIGESTIBILITY OF BROILER CHICKEN. As an animal feed, maggot from black soldier fly (Hermetia Illucens) has high calcium (Ca)  and phosphorus (P) content. Yet, little is known about the digestibility of calcium (Ca) and phosphorus (P) in the diet containing maggot. The present study was designed to determine the effect of substitution of fish meal with maggot (Hermetia illucens) meal in the diets on (Ca) and phosphorus (P) digestibility of broiler chicken. Twenty day old chicks (DOC) CP 707 broiler chicken of about 1300-1500 g body weight were assigned to each dietary treatment which was replicated four times in a Completely Randomized Design (CRD) arrangment. The experimental diet consisted of 5 treatments and 4 replications, formulated as follow: R0 = 100% fish meal  + 0% maggot meal; R1 = 75% fish meal + 25% maggot meal; R2 = 50% fish meal + 50% maggot meal; R3 = 25% fish meal + 75% maggot meal; and R4 = 0% fish meal + 100% maggot meal. Calcium (Ca) and phosphorus (P) digestibility were calculated using total collection method. Parameters measured were calcium (Ca) and phosphorus (P) digestibility. Differences were considered significant at P < 0.05. Tukey test (HSD) was employed to further analyze among treatment diferences. The results showed that calcium (Ca) digestibility was significantly (P < 0,05) increased as the level of maggot (Hermetia Illucens) meal in the diets increased; whereas the digestibility of phosphorus (P) was not significantly (P > 0,05) affected by the treatments. It can be concluded utilization of maggot (Hermetia illucens) meal up to 100% replaced fish meal or  15% in the diet, inreased calcium (Ca) digestibility and did not affect phosphorus (P) digestibility of broiler chicken.   Key words: Fish meal, Maggot (Hermetia Illucens) meal, Calcium and Phosphours digestibility

Abstract

THE FFECT OF SOME TYPES OF FORAGE FOR LIVESTOCK PERFORMANCE RABBIT. Rabbit productions may have considerable potential in developing counties as a means of converting forages and agricultural by product to meat. The present study was conductes to laborate leaves, and their combinations in the diets on rabbit performance. Twenty one 6-week old weaned rabbits, weighing 300-400 gramns were used in this trial. Animals were put in individual metabolic crates. A Completely Randomized Design with 7 treatments and 3 replications was used as an experimental design and Tukey test was employed to determine treatmen differences. Treatments were arranged as: R1 : carrot leaves + concentrate; R2 : kale leaves + concentrate; R3 : cabbage leaves + concentrate; R4 : carrot and cabbage leaves + concentrate; R5 : kale and cabbage leaves + concentrate; R6 carrot and  kale leaves; R7 : carrot + kale + cabbage leaves + concentrate. Parameters measured were; daily feed consumption, daily gain, and feed conversion ratio. Research result showed that treatments significantly affected daily feed consumption, daily gain, and feed convertion ration be concluded that the combination of carrot and cabbage leaves can support rabbit performance in the present study. Keywords : Rabbit, daily feed consumption, daily gain, feed convertion ratio.

Abstract

EFFECT OF SUBSTITUTION OF RICE BRAN WITH COFFEE HUSK MEAL IN THE DIETS ON ENERGY AND PROTEIN DIGESTIBILITY   OF GROWING PIGS. A study was conducted todetermine the effects of substitution of rice bran with  coffee husk meal in the diets on energy and protein digestibility of growing pigs. The present study was conducted for 60 days, using 20 castrated male Duroc X Spotted Poland China, aged 2.5–3.0 months with an averaged body weight of 30.1–40.0 kg. Treatment diets were formulated as follow: R0 = 25% rice bran + 0% coffee husk meal (without coffee husk meal); R1 = 18.75% rice bran + 6.25% coffee husk meal (substitution of 25%); R2 = 12.5% rice bran + 12.5% coffee husk meal (substitution of 50%); R3 = 6.25% rice bran + 18.75% coffee husk meal (substitution of 75%); and R4 = 0% rice bran + 100% coffee husk meal (substitution of 100%). Completely Randomized Block Design (CRBD) with 5 treatments and 4 replications (blocks) was used as a statistical analysis (Anova). An Orthogonal Contrast test was further employed to analyze treatment differences. Different between treatment (s) was declared at P < 0,05. Parameters measured were energy and protein digestibility. Research results showed that there was no significant differences (P > 0,05) were found among treatments on energy and protein digestibility. It can be concluded that coffee husk meal can be used up to 100% to replace rice bran or 25% in the diets of growing pigs.Key words: Pig, rice bran, coffe husk, energy, 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

UTILIZATION EFFECT OF MOLASSES AS ENERGY SOURCE IN THE DIETS ON GROWING RABBIT PERFORMANCE. Molasses had been used previously in animal feeds. The present study was conducted to determine the effect of molasses utilization in the diets on growing rabbits. The study was conducted during five weeks at Department of Animal and Feed Science Laboratory, Faculty of Animal Husbandry, University of Sam Ratulangi, Manado. Twenty eight-weeks weaned female rabbits with an initial body weight of 600 -700 gr were used in this trial. Animals were allocated in an individual cage. A Completely Randomized Design (CRD) with 4 treatments and 5 replications was used for analysis of variance. Treatments were formulated as follow: R0 = 100% basal diet + 0% molasses; R1 = 98% basal diet + 2% molasses; R2 = 96% basal diet + 4% molasses; and R3 = 94% basal diet + 6% molasses. Variables measured were daily feed consumption, water consumption, daily gain, and feed conversion. Research results showed that average daily feed consumption in the present study ranged from 58.1 to 60.4 g; daily water consumption from 127.2 to 163.8 liters; daily gain from 20.1 to 20.9 g; and feed conversion ratio of about 3.57 to 3.80. Statistical analysis revealed that utilization of molasses replacing part of basal diets up to 6% gave no significant differences on daily feed consumption, water consumption, daily gain, and feed conversion ratio.  It can be concluded that molasses as an energy source can be utilized up to 6% in growing rabbit diets without any negative effects. Keywords: Molasses, diets, growing rabbits performance
