Abstract

The purpose of this research was to examine the carcass quality and meat quality of native chicken fed dried tomato meal in diet. The study was conducted by using 200 heads of native chickens 10 days. The birds were divided into five experimental diets and each was divided into four replicate groups of ten birds per replicate. The based diet was formulated to contain 42% corn, rice bran 9%, fish meal 10%, fish oil 5%, soybean meal 9% and commercial diets 25%. Tomato meal was included in five experimental diets at levels of 0, 3, 6, 9, 12% to substitute based diets. The treatments were PO = 100% based diet (BD) + 0% tomato meal (TM); P1 = 97% BD+ 3% TM; P2 = 94% BD + 6% TM;P3 = 91% BD + 9% TM; P4 = 88% BD + 12% TM. Chemical composition of tomato meal was: 20.73% crude protein, 1.53% fat, 30.94%crude fiber, 0.98% Ca, 1.20% P and 2,416 kcal/kg of Gross Energy (GE). Results showedthat feeding tomato meal at an inclusion rate of 12% increased slaughter weight, carcass, breast meat, wings, drumstick and thigh, and decreased abdominal fat and blood cholesterol. Moreover, there were no significant difference in giblet (liver, heart and gizzard) between treatments. Meat water and meat crude protein were significantly increased. Meat crude fat and meat cholesterol were significantly decreased. In conclusion, tomato meal can be used as an alternative feedstuff in kampong chicken diets at inclusion levels up to 12% without negative effects on carcass quality and meat quality.

Abstract

This study was conducted to investigate the effect of different level of energy and crude fiber in diets containing sawdust on carcass quality of broilers. A total of 120 broilers were used for the research. The experiment utilized a completely randomized design in 2 x 3 factorial arrangement of treatments consisting of two dietary concentrations of energy and three dietary concentrations of crude fiber. Each treatment consisted of 4 replications (5 birds each) was reared during 35 days. The birds were housed in battery cages with ad libitum access to feed and water. During the experiment, feed intake, carcass yield, abdominal fat, blood LDL-cholesterol and HDL-cholesterol were measured. Data were subjected to the analysis of variance test followed by least significant difference test (LSD). Results showed that the diet with 3,100 Kcal/kg ME and 11% crude fiber significantly decreased feed intake, abdominal fat percentage, and blood LDL-cholesterol, but did not affect final body weight and the value of blood HDL-cholesterol and had the good value of carcass percentage. The diets containing sawdust with higher level of energy content decreased feed intake and the higher level of crude fiber decreased final body weight, carcass percentage and abdominal fat. Optimum broiler performance and carcass quality was obtained by diet formulated to contain 3100 Kcal/kg ME and 11% crude fiber.

Abstract

The study was conducted to evaluate the effect of level of banana (Musa paradisiaca) leaves fermented with Trichoderma viride at different days on the carcass yield of broiler chickens. A hundred and eighty 3-weeks-old broiler chicks were used in this present experiment based on factorial design (3×4). The birds were randomly allocated into three experimental diets containing of 5, 10 and 15% of banana leaves fermented within 0, 5, 10 and 15 days. Each treatment was divided into three replicates of five chicks in each. The experiment was terminated after 4 weeks or when the birds were 7-weeks-old. Feed intake, body weight gain, feed efficiency and carcass yield were measured during the study. The data were subjected to the analysis of variance test followed by least significant difference (LSD) test. Results showed that daily feed intake was significantly affected (P˂0.01) by the dietary treatments, in which feed intake was highest in broilers fed diet containing 10% banana leaves fermented for 10 days. The daily weight gain, feed efficiency and carcass yield were significantly affected (P˂0.01) by the treatments, in which the highest values of daily weight gain, feed efficiency, and carcass yield were observed in birds fed diet containing 10% banana leaves fermented for 10 days. It can be concluded that diet containing 10% banana leaves fermented for 10 days can be included in broiler ration without detrimental effects on the performance and carcass yield.

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

The study was conducted to analyze the phytochemicals of basil leaves (Ocimum x citriodorum L.)and to evaluate the effect of basil leaves juice as an additive on nutrient digestibility of broilerchicken diet. This study used 20 male broilers (35 days old). The research parameters werephytochemical, proximate, and digestibility analysis. The data of basil leaves phytochemical andproximate analysis were analyzed using descriptive analysis. The digestibility were analyzed usinga Completely Randomized Design (CRD) by 4 treatments and 5 replications. The research wasconducted for 10 days consisting of 7 days for maintenance period and 3 days for total collectionperiod. The digestibility treatments consisted of 0 mL, 10 mL, 20 mL, and 30 mL basil leaves juice/Ldrinking water. The results showed that giving basil leaves juice had a good effect on nutrientdigestibility of broiler chickens and could be used up to 20 mL/L in drinking water.

Abstract

This research was conducted for 3 months in the laboratory of the Department of Animal Husbandry, State University of Gorontalo. This study used an egg sample of 240 eggs of purebred chickens. Eggs were divided into 4 treatments, each treatment was repeated 3 times. A0 = 0% (eggs without treatment), A1 = 10% (eggs soaked at 10% level of water hyacinth leaf extract), A2 = 20% (eggs soaked at 20% level of water hyacinth leaf extract), A3 = 30% (eggs by immersing 30% level of water hyacinth leaf extract). B0 (1 day old egg), B1 (14 day old egg), B2 (21 day old egg), B3 (28 day old egg). The research was conducted by measuring egg weight, air voids, HU value, egg yolk color, and taste. Flavor. Data were analyzed using a completely randomized design (CRD), and further tests were carried out using Duncan's test. The results of this study showed that the effect of tannin content on the level of 20% water hyacinth leaf extract was able to maintain egg quality compared to eggs that were not given treatment (control). Because the tannin solution derived from water hyacinth leaves is able to cover the egg shell pores properly.
