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

Research was aimed to determine nitrogen balance, microbial protein synthesis, and blood metabolites of male Bali cattle fattening fed ration with different protein level in smallholder farms North Central Timor, Province of East Timor Tenggara, Indonesia. The cattle used were 18 heads aged 2 to 2.5 years with initial body weight of 229.86±12.46 kg. The cattle were randomly divided into three treatment groups. The T0 group was given feed the same as traditional fattening cattle practices by farmers,T1 group fed ration containing 12% crude protein (CP) and 72% total digestible nutrients (TDN), andT2 group fedration containing 15% CP and 72%TDN. Cattle were fed individually for 90 days and drinkingwater ad libitum. The data were analyzedby analysis of variance.Results of research indicated the nitrogen balance, and blood urea nitrogen between T1 and T2 were relatively similar, but those were higher (P<0.05) than T0 . In contrast, microbial proteins synthesis, and blood glucose at 0, 4, and 6 hours before and after feeding were relatively similar between the groups. Blood glucose of T2 at 2 hours after intake were higher (P <0.05) than T0, but was not different with T1 . It can be concluded, that the fattening maleBali cattle fed ration containing 12% CP and 72% TDNimprovedthe nitrogen balance and blood metabolites, butit was no positive effect on the microbial proteins and N synthesis.

Abstract

Growth hormone gene that controls metabolism and body size of animals and polymorphism of the gene is known related to performance of livestock. Identification of gene polymorphisms was important to get early information to determine genetic markers associated with economically desirable traits. Genetic mapping is one of important characterizations in the selection process. Pesisir cattle is one of local cattle in Indonesia that are reared in West Sumatera and have become adaptive to local environment. The present study aimed to identify the genotype of Growth Hormone gene (GH891│MspI) of the Pesisir cattle and crossbred Simmental-Pesisir cattle (designated as SimPes) and relationship between growth performance (body weight and body size). The present study was conducted to 30 blood samples consisted of 15 Pesisir cattle and 15 SimPes cattle. Body weight and body size were measured at 12-18 months of age. The Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method was used in this research. The results showed that there exist three variant genotypes (MspI-/-, MspI+/-, MspI+/+) and that allele frequencies of MspI- and MspI+ were 53.3% and 46.7%, respectively. Non-significant effect has found between GH’s genotype and growth traits (Body measurement and body weight) in both of breed cattle. In conclusion, three variant genotypes (GH891│MspI) in Pesisir and SimPes (Simmental x Pesisir) cattle population were found and no significant effect on growth trait performance.

Abstract

The present study was conducted to evaluate the effect of medicinal herbinclusion on fat deposition, chemical composition, amino acid and fatty acid ofbroiler meats. One hundred-sixty eight female broiler chickens aged 15 days were distributed into 7groups as follows: 1) broilers were fed a diet with no medicinal herb as the control (P0) 2) broilers were fed a diet with 5% Sauropus androgynus leaf powder (P1); 3) broilers were fed a diet with 5% bay leaf powder (P2); 4) broilers were fed a diet with 5% basil leaf powder (P3) 5) broilers were fed a diet with 5% papaya leaf powder (P4); 6) broilers were fed a diet with 5% Moringaleaf powder (P5) and; 7) broilers were fed a diet with 5% noni fruit powder. Experimental results showed that the inclusion of medicinal herbs significantly increased protein (P<0.01), iron(P<0.05), kalium, calcium, phosphorus, linolenic acid(P<0.01), methionine, omega 3 unsaturated fatty acid (P<0.05), but significantly reduced fat (P<0.01), glutamic acid, alanine, lignoceric acid, oleci acid (P<0.01) and omega 9 unsaturated fatty acid (P<0.05). It was concluded that Sauropus androgynus leaf was the most effectiveto produce low fat-high protein and mineral meats.

Abstract

This experiment was conducted to study the morphometric and genetic diversity of Tegal, Magelang, and their crossbred ducks. Each ten female about twenty weeks old ducks from Tegal, Magelang, Gallang, and Maggal ducks, respectively, were used as the group materialss. The body weight, chest circumference, body length, shank length, neck length, and pubis width were recorded and tested by analysis of variance of one way classification as the morphometric characteristics. Polymorphism of cytochrome b (cyt b) gene on mitochondrial DNA (mtDNA) was analyzed by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). Genetic distance was analyzed based on value of heterozygosity, whereas the phylogeny tree was reconstructed using MEGA6 software. The results showed there were highly significant difference (P<0.01) on body weight, chest circumference, body length, and neck length between population, while shank and pubis width were not significant different. The genetic distance between Gallang and Maggal ducks (0.206) was higher than Tegal and Magelang ducks (0.169). It is concluded that the reciprocal crosses increased the morphometric and genetic diversity of Indonesian local duck population.

Abstract

An experiment was conducted to study the effect of curcumin supplementation inexpose monochromatic light on serum lipid concentrations of sexually mature female magelang duck. One hundred and ninety two female magelang ducks were assigned into a completely randomized design with a 4×4 factorial arrangement and each experimental unit was repeated 3 times, each with 4 female magelang ducks. The first factor was dose of curcumin supplementation consisted of 4 levels i.e., 0, 9, 18, and 36 mg/duck/day. The second factor was the color of monochromatic light consisted of 4 levels i.e., white, red, green, and blue colors. The data were analyzed by two-way ANOVA. The result showed that serum concentrations of triglyceride, cholesterol, very low density lipoprotein (VLDL), and low density lipoprotein (LDL) were lower (P<0.05) while high density lipoprotein (HDL) were higher (P<0.05) in experimental ducks supplemented with a curcumin dose of 36 mg/duck/day in variety of monochromatic light colors compared to control experimental ducks without curcumin supplementation. The curcumin doses of 18 or 36 mg/duck/day within red, green, or blue light had the potential to modulate lipid metabolism, as indicated by the increased serum concentration of HDL and the decreased serum concentrations of triglyceride, cholesterol, VLDL, and LDL of the experimental female magelang ducks.
