Abstract

This study was conducted to determine the effect of Citrus hystrix as fat protector on unsaturated fatty acids, cholesterol and chemical composition of lamb meat. The research design applied was completely randomized design with 3 treatments and 5 replications. Fifteen local male lambs aged 9-12 months weighing 14-17 kg, were divided into 3 groups of different diet treatments (P0 : sheeps were only given a basal diet; P1 : sheeps are given basal diet and 3% cooking oil; P2 : sheeps are given basal diet, 3% cooking oil and protected by 3% Citrus hystrix powder). The data were analyzed by analysis of variance, the differences among treatments were tested by Duncan’s New Multiple Range Test. The results showed meat from sheeps that consume P2 diet has a total fatty acid and polyunsaturated fatty acids content were higher (P

Abstract

The research aim was to study the variance of some morphometric characteristics and morphologyof Moa buffalo, and the genetic relationships analysis between buffalo subpopulations in Moa Island.Characterization was by using 174 buffalos from any group of ages and sex that were collected fromWest area (Werwaru, Patti), Central area (Syota, Klis) and East area (Tounwawan, Poliwu). Thevariables observed were morphometric characters (body weight, shoulder height, body length, chestwidth, chest depth, chest girth, skull length, skull width, skull height, ear width, ear length, cannon girth,horn length, horn girth and distance between horns), body morphology characters (horn position, headcolor, body color and scheme of body color), and genetic distance between buffalo subpopulations.Body morphometric data were analyzed using mean, standard deviation and variance coefficient. Bodymorphology data were analyzed using relative frequencies. The genetic distance was analyzed usingcanonical discriminant function through Mahalanobis distance approach and by making phylogeny usingUPGMA method. The result indicated that variation of body morphometric was related to productionperformance, variation of color and color scheme of body. Based on genetic distance, central and westsubpopulations were the nearest where West subpopulation was isolated from Central and Eastsubpopulation.

Abstract

A field experiment was conducted on Chromolaena odorata dominated pasture with the objectivesof evaluating efficacy of integrated of mechanical and cultural control on weed suppression anddetermining botanical composition of plant species after treatment started. The treatments were, T1slashing of Chromolaena every month, T2 digging up of Chromolanea, and exposed to dry (mulching),T3 digging up of Chromolaena followed by burning, T4 digging up of Chromolaena followed byburning and sowing with Centrosema pubescens and T5 digging up of Chromolaena followed byburning and planting with Brachiaria decumbens. Results of experiment showed that under droughtconditions, digging up Chromolaena was very effective in suppressing regrowth of Chromolaena but itwas not effective to other weeds. Among treatments, digging out of Chromolaena followed by burningand planting with Brachiaria decumbens was the most effective and slashing of Chromolaena everymonth was the least effective in suppressing weeds. Botanical composition was shifted with treatments.Stachytarpheta jamaicensis and Chromolaena were the dominant species in monthly slashedChromolaena plots, Stachytarpheta and Calopogonium muconoides were the dominant species inmulched plots while Mimosa pudica, Brachiaria and Centrosema were the dominant species in burntplots.

Abstract

The study was aimed to evaluate the effectiveness of feeding dietary microparticles protein added with Lactobacillus sp. on blood parameters and broiler productivity. A total of 192 birds of 21 days old broiler with initial body weight of 481 ± 67 g were divided into 8 treatments and 4 replications (6 birds each) of a completely randomized design (CRD). Dietary treatments were T0: 21% intact protein ration, T1: 18% intact protein ration, T2: 21% microparticle protein ration, T3: 18% microparticle protein ration, T4: T0 + 1.2 mL Lactobacillus sp, T5: T1 + 1.2 mL Lactobacillus sp., T6: T2 + 1.2 mL Lactobacillus sp., and T7: T3 + 1.2 mL Lactobacillus sp. Parameters observed were total lactic acid bacteria and Coliform, pH, blood cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), meat cholesterol, meat weight, feed consumption, and body weight gain (BWG). Data were analyzed using analysis of variance and followed by Duncan test (P<0.05). The results showed that T7 treatment significantly (P<0.05) decreased blood cholesterol, LDL, and meat cholesterol, but increased HDL, meat weight, and BWG. Blood cholesterol, LDL, and meat cholesterol were indicated significantly (P<0.05) lowest values due to T7 treatment. In conclusion, feeding 18% microparticle protein with addition of 1.2 mL Lactobacillus sp. can improves blood status and increases broiler productivity.

Abstract

The purpose of this research was to produce the enriched eggs, but low in cholesterol content. Forty eight layer chickens aged 72 weeks (strain Dekalb Warren) were distributed into six treatment groups. One group of laying hens was fed diets without Sauropus androgynusleaf extract (SALE) as the control, and another five groups were fed diet supplemented to 9 g SALE, 18 g SALE, 27 g SALE, 36 g SALE, and 45 g SALE/kg diet, respectively. Completely randomized design was used in the present study.The experimental results showed that SALE supplementation had no effect on egg production, feed intake, feed conversion ratio, egg weight, yolk weight, albumen weight, shell egg, egg index, eggshell thickness, and yolk index (P>0.05), but significantly affected Haugh Unit, albumen index, yolk color, egg odor, egg taste, and yolk color (P<0.05). The protein, fat, calsium, phosphor, kaliumand iron contents of eggs  did not change (P>0.05), but the cholesterol content of egg was significantly reduced (P<0.05). In conclusion, the supplementation of SALE did not enhance performance, but it improve egg quality and its chemical composition.

Abstract

The present study was conducted to evaluate the effect of Sauropus androgynus (katuk) leavesextract (SAE) and lemuru fish oil (LO) on fat deposition and fatty acid composition of meat in broilerchickens. One hundred and fifty six broiler chickens were distributed to 13 treatment groups with 3cages in each treatment group as replicate. Completely randomized design was used in this study. Thethirteen groups were subsequent of broiler chickens that were fed diet containing commercial feedsupplement as a control (P1), 10 g/kg SAE and 1% LO (P2); 10 g/kg SAE and 1% LO plus 60 mgvitamin E (P3), 10 g/kg SAE and 2% LO (P4), 10 g/kg SAE and 2% LO plus 60 mg vitamin E (P5), 10g/kg SAE and 3% LO (P6), 10 g/kg SAE and 3% LO plus 60 mg vitamin E (P7), 18 g/kg SAE and 1%LO (P8), 18 g/kg SAE and 1% LO plus 60 mg vitamin E (P9), 18 g/kg SAE and 2% LO (P10), were18 g/kg SAE and 2% LO plus 60 mg vitamin E (P11), 18 g/kg SAE and 3% LO (P12), and 18 g/kg SAEand 3% LO plus 60 mg vitamin E (P13). The data were analyzed by analysis of variance and if it weresignificant, it were then determined by Duncan's Multiple Range test. The present results showed thatsupplementation of SAE and LO significantly affected (P<0.05) fat deposition in abdomen and leg, butit had no effect on neck fat deposition and Fatty Liver Score. Supplementation of SAE and LO hadsignificantly reduced (P<0.05) cholesterol content and thiobarbituric acid (TBA) in leg meat, but itsignificantly increased (P<0.05) vitamin A and vitamin E and it had no effect on fat in leg meat.Supplementation of SAE and LO proved to change fatty acid composition in leg meat. The treatmenthighly significant increased ecosapentaenoic acid (EPA) and docosahexaenoic acid DHA (P<0.01),arachidonic acid and stearic acid (P<0.05), but it significantly reduced linolenic acid (P<0.05). Inconclusion, the supplementation of SAE and LO reduced fat deposition in abdomen and leg, the contentof cholesterol in meat, and it enriched EPA and DHA of meat.

Abstract

The aim of the study was to assess microbiological properties of beef sold in various meatshops in Semarang. There are five Indonesian goverment standard requirements to maintain the qualityof beef sold in Indonesia markets, as follows: (1) total plate count (TPC) for a maximum of 106 CFU/g,(2) total coliform bacteria for a maximum of 102 CFU/g, (3) total Escherichia coli up to 10 CFU/g, (4)total Staphylococcus aureus for a maximum of 102 CFU/g and (5) negative for Salmonella per 25 gsamples (SNI 3932, 2008). Beef samples were randomly taken from several traditional markets, meatshops and supermarkets. The result showed that all samples did not contain Salmonella but still couldnot meet one or some of the Indonesian government standard regulation. In conclusion, beef samplesgathered from some of the markets, generaly could not meet one or some of the five strictlyrequirements of the bacteriological properties.

Abstract

The objective of the current study was to evaluate the impacts of feed restriction (FR) for 3 hours and/or dietary supplementation with vitamins and minerals on growth, mortality rate, some carcass traits, and serum biochemistry indices of broiler chicks under heat stress in the open housing system. A total of 240 one-week old broilers were weighed and randomly assigned into 4 equal experimental treatments. Treatment 1 (T1) was fed ad libitum on basal diets, T2 birds were fed on basal diets with FR, T3 birds were fed ad libitum on basal diets with vitamin C (200 mg) + vitamin E (200 mg) + Cr (1.5 mg ) + Zn (100 mg) per kg diet, and T4 birds were fed on basal diets with FR and combined supplementation of vitamins and minerals. It was found that growth parameters improved in T2, T3, and T4, while the mortality rate was significantly reduced compared with control. FR and feed additives (T4) revealed marked increases in serum total protein and a decrease in total serum cholesterol. It was concluded that combined effect of FR and feed additives could significantly alleviate heat stress effects for broilers by improving growth performance and decreasing mortality rate.
