Abstract

The aim of this research was to evaluate the nutrient degradability, in vitro methane (CH4) production ofseveral agricultural and food industry by-products in relation to their chemical composition. Twenty-onesamples of 7 feedstuffs from agricultural and food industry by-products consisted of corn straw, potatostraw, rice straw, cocoa pod, sago waste, rice bran, soybean curd residue were evaluated by an in vitro gasproduction and nutrient degradability. The feedstuffs varied greatly in their crude protein (CP), neutraldetergent fiber (NDF) and non-fiber carbohydrate (NFC) contents. Crude protein ranged from 1.5 to 21.8%,NDF from 31.6 to 71.1% and NFC from 1.5 to 50.8%. Among the seven feedstuffs, soybean curd residuehad the highest CP content, on the other hand it had the lowest NDF content. Dry matter (DM) and organicmatter (OM) degradability were highest (P<0.01) in soybean curd residue among the feedstuffs. The CH4production was significantly higher (P<0.01) in rice straw, cocoa pod and corn straw as compared to sagowaste. There was a strong positive correlation (r = 0.60; P<0.01) between NDF concentration and CH4production. However, the total gas productions was negatively correlated (r = -0.75; P<0.01) with NDFcontent. The CH4 production of feedstuff is influenced by NDF content.

Abstract

The aim of the research was to evaluate the genetic improving of production traits selected of Balicattle. Four hundred and twenty eight data of weaning weight, yearling weight and body weight gainwere used to estimate genetic improvement for those traits. One hundred and seven data of bodydimension (body weight, chest circumference, body length and withers height) at 24 months old wereused to estimate genetic improving for those traits. The estimation of genetic and environmentalvariance and co-variance component, and heritability were found by animal model. The fix effect ofweaning weight, yearling weight and body weight gain was rainfall, age of measurement and year ofbirth, whereas the fix effect of body dimension depend on each trait. The result showed that heritabilityof weaning weight, yearling weight, body weight gain, body weight, chest circumference, body lengthand withers height was 0.090.15, 0.270.13, 0.470.15, 0.070.19, 0.500.19, 0.340.28, 0.600.21,respectively. Genetic improvement of all traits have had a different pattern in selection responses. Alltraits did not show genetic improvement due to selection for.

Abstract

This research aimed at investigating the effect using molasses and cornmeal as additives with Lactobacillus sp. and Streptomyces sp. as inoculums during fermentation on the quality of silage flour made from dead chickens. The study was conducted using a completely randomized factorial design, consisting of 2 factors with 5 replications. The materials used were the newly dead chickens which were chopped and mixed thoroughly with all ingredients; then transferred into a 5 liters plastic box for fermentation. Observations were made after 3 weeks fermentation, including: a) physical characteristics, b) microbial contents, and c) nutritional contents. The data were calculated using variance analysis utilizing computer program of SPSS version 21.0. It was found that based on the protein contents the Lactobacillus sp. (19.0%) was better than the Streptomyces sp. (17.8%) if combined with molasses and corn meal as the accelerators. However, the fat contents produced were relatively similar for both of the inoculums (mean of 37.8%). It can be concluded that in order to obtain a best fermented product in terms of the protein and fat content, the dead chicken should be fermented using molasses and cornmeal as the accelerator and Lactobacillus sp. as the inoculum.

Abstract

This study was conducted to compare ruminal Volatile Fatty Acids (VFA) concentration andblood glucose in young and mature Kacang goats at different feeding levels. Eigth male young Kacanggoats weights at 12.75±2.68 kg (6-7 months) and male mature goat weights at ± 17.34±3.32 kg (8-12months) were used in this study. The pelleted complete feed was formulated to give 18,8% of CrudeProtein (CP) and 78.82% of total digestible nutrients (TDN). The experiment design was nested designexperimental 2x2 with 4 replications. The main factors (based on nested) were young and mature goatsand the second factor was low feeding (near maintenance level) and high feeding (2X maintenance).Data measured were daily feed intake, feed digestibilities, ruminal VFA concentration and bloodglucose. The data obtained were analyzed by using analysis of variance. The results showed that drymatter intake (DMI), digestible carbohydrates, digestible crude fiber, and digestible organic matter wasaffected by age (P<0.05), as well as level of feeding (P<0.001), but age and feeding level has no effecton digestibility (P>0.05). Ruminal VFA and blood glucose concentrations were found similar (P>0.05) neither in young and mature goats. However, VFA and concentration on the 3 and 6 h on high feeding aswell as blood glucose on 3 h in high feeding were higher than those on low feeding.

Abstract

This research was conducted to evaluate the effect of inoculants consortium consisted ofLactobacillus plantarum (Lp) and Saccharomyces cerevisiae (Sc) and combined with rice bran additionon microbiological characteristic and fermentability of king grass (Pennisetum hybrid) silage. Effectivityof treatments was assessed by addition of inoculants (control, Lp, Lp+Sc) and level of rice bran (0, 5 and10%) which were arranged on Completely Randomized Design with Teatments Factors (3x3). Thevariables measured were total colonies of microbes (lactic acid bacteria, yeast and clostridia), total gasproduction, volatile fatty acids (VFA) and ammonia (NH3). Results showed that clostridial coloniescounted on silage treated by Lp and Lp+Sc around 37.5% and 68.7% in which lower than control.Addition of inoculants and rice bran increased fermentability of silage significantly (P<0.05), howevertreatment had no affected (P>0.05) on production of VFA and NH3. Gas production from silagefermentable fraction with inoculation of Lp (49.5 ml) and Lp+Sc (47.9 ml) higher than untreated silage(46.6 ml). It was concluded that the use of inoculants consortium consisted of L. plantarum and S.cerevisiae with rice bran addition improved fermentability and reduced clostridial colony in king grasssilage.

Abstract

Crossing between cattle breeds is the one way to improve the genetic quality of cattle. Controlling crosses using genetic markers will speed up the process. The IGFBP-3 gene is a potential marker of selection due to its role in regulating growth and metabolism in cattle. The aim of this study was to determine the effect of genotype on birth size and birth weight using IBFBP-3 gene marker. A total of 32 cattle consisted of 10 Brahman Cross cattle, 14 cattle results of Brahman Cross cow crosses with Belgian Blue bull, and 8 cattle results of Brahman Cross cow crosses with Wagyu bull. Sequences of 563 bp, including the part intron 2, exon 3, and the part intron 3. Genotyping was done by sequencing method and PCR-RFLP method with the restriction enzyme PvuII. An SNP was identified at location g 3,930 (G>A). Two genotypes were observed, namely GA and GG. The genotype did not affect the performance of birth (body weight, body length, height at withers, heart girth) of the research sample. Birth traits are influenced by the cattle breed, it can be seen that Brahman Cross cattle have a body length that is bigger than the other crossbred.

Abstract

The aim of this research was to observe body (neck, chest and scrotum) circumferences and testosterone level of α-male, β-male and subordinate male Timor deer reared under captivity after establisment of the dominance hierarchy. Twelve males (51 ± 6 months old; 68.29 ± 8.41 kg body weight and in same antler stages) were used in this research. The bucks was grouped into three stall each containing four bucks. ELISA kit and tape measurements were used for plasma Testosterone assay and body measurement, respectively. Data was collected before and 43 days after establishment of the dominance hierarchy. Wilcoxon signed ranks test and Kruskal-Wallis H test of non-parametric analysis was used. Significant difference was tested with Mann-Whitney U test. The results showed no significantly different for body circumferences (neck, chest, scrotum) and testosterone level of male Timor deer before establishment of dominance hierarchy. Chest and scrotum circumferences of male Timor deer after establihment of dominance hierarchy showed no significantly different. Significantly difference shown on parameter neck circumference (P<0.05; χ2 = 8.74) and testosteron level (P<0.05; χ2 = 7.87) after establishment of dominance hierarchy. In conclusion, dominance hierarchy affected the testosterone level and body measurement.

Abstract

The objectives of this research were to determine efect of material and fermentation time on qualityand digestibility of fermented complete feed, average daily gain (ADG) of Bligon goats and farmer’sincome. The research was conducted during twelve weeks in the housing of goat farmers atPurwomanunggal farmers’ group, Panggang, Gunung Kidul district. Fifteen Bligon male goats, 8 monthsof age and 12 to 15 kg of body weight, were randomly divided into three treatments, each groupsconsisted of five goats. The treatments were: control feed (R0 ), one week fermented complete feed (R1),and two weeks fermented complete feed (R2). Data were analyzed with ANOVA based on one waycompletely randomized design and continued with Duncan's multiple range tests for significantdifferences. Result showed that complete feed fermented for two weeks had darker color and strongerodors compared with one week fermentation. Both fermented complete feed (one and two weeks) hadsoft textures, no fungi with pH ranged from 4.5 to 5.0. Total digestible nutrient (TDN) intake wassignificantly affected by the treatment. The treatment had no significant effect on acid detergent fiber(ADF) and neutral detergent fiber(NDF) digestibility, average daily gain, and farmer’s income.
