Abstract

THE EFFECT OF YELLOW PUMPKIN (Cucurbita moschata) MEALIN THE DIET ON THE CARCASS, CARCASS COMMERCIAL CUTTING AND ABDOMINAL FAT OF BROILER CHICKENS. This study aims to determine the effect of pumpkin (Cucurbita moschata) waste in the diet on carcass percentage, commercial cutting of carcass (breasts, thighs, wings) and abdominal fat in broilers. The study used 100 unsexed D.O.C. of broilers, strain Cobb. The experiment used a completely randomized design (CRD) consisting of 4 treatments and 5 replications. The follow-up test used was Honest Real Difference (BNJ). The treatment arrangements are as follows: R0 = Basal Diet (BD) 100% + 0% Yellow Pumpkin Meal (YPM); R1 = BD 95% + 5% YPM; R2 = BD 90% + 10% YPM; R3 = BD 85% + 15% YPM. The results showed that carcass weight and carcass percentage in treatment R0, R1, R2 were significantly higher than treatment R3, but between treatments R0, R1, R2 were not significantly different. The commercial section of the right chest of treatment R1, R2, R3, was significantly higher than the R0 treatment, but between treatments R1, R2, R3 were not significantly different, while on the left chest showed that treatments R0, R2, R3 were significantly higher than R1, however, between treatments R0, R2, R3 were not significantly different. Thigh and wing sections, and abdominal fat percentage showed no significant differences. Based on the results, it can be concluded that15% pumpkin waste mealin broiler diet has a good effect on body weight growth, carcass percentage and part of the commercial cutting percentage of broiler carcass.

Abstract

ABSTRACT THE VALUE OF NITROGEN RETENTION AND METABOLIZABLE ENERGY OF BROILER DIETS WITH MUSTARD MEAL (Brassica rapa L. subsp. pekinensis) This research was conducted  to determine the value of nitrogen retention (NR) and nitrogen corrected metabolizable energy value (AMEn) of broiler diets containing waste of mustard meal. Research used 18 MB 202 of broiler chickens 6 weeks of age that consists of 3 days of preliminary and 3 days collecting data. The experimental wasdesigned by a completely randomized design (CRD), which consists of 3 treatments and 6 replications. The treatmentswere: R0 = 100% based diet (BD) + 0% mustard waste meal (MWM), R1 = 90% BD + 10% MWM, and R2 = 80% BD + 20% MWM. Variables were nitrogen retention (NR) and metabolizable energy  nitrogen corrected (AMEN) value. Results showed that the NR value was significantly (P <0.05) affected by treatments and the AMEn was highly significant (P <0.01) affected by treatments. HSD test showed thatthe NR value of R1(54,59%) and R2  (41,71%) was significantly decreased compared to control (41,71%).The AMEn value oftreatment R1 (2504.07 Kcal/kg) and R2 (2117.00Kcal/kg) was signicantly decreased compared to R0 (3141.57 Kcal/kg). Based on the NR and AMEn values, it can be concluded that mustard waste could be used up to 10% in dietof broilers Keywords : broiler, metabolizable energy,mustard, nitrogen retention,

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.

Abstract

UTILIZATION  OF BANANA CORM (Musa paradisiaca L.) IN DIET ON BROILER CHICKENS PERFORMANCE. The research on the utilization of banana (Musa paradisiacaL.) corm in broiler diet aimed to determine its effect on the performance of broilers, namely the feed intake, weight gain, and feed conversion ratio. The birds used were 100 unsexed days old chicks. This study used a Completely Randomized Design (CRD) consisting of 4 treatments and 5 replications. The composition of the treatment as follows: R0 = 55% corn + 0% banana corm meal (BCM), R1 = 50% corn + 5% BCM, R2 = 45% corn + 10% BCM, R3 = 40% corn + 15% BCM. The result showed that the treatment had a significantly different effect on feedintake, body weight, and feed conversion ratio. Based on the results of the study, it was concluded that banana corm can be used up to 10% in broiler chicken diet.
