Abstract

The bone morphogenetic protein 15 (BMP15) gene or commonly called FecX (fecundity chromosome X) is a gene that controls the prolific properties. This study aims to identify the mutation of BMP15 gene and to analyze its polymorphism in Boer, Kacang, and Boerka goats. The total of 50 female goat bloods were identified using PCR-Sequencing method, 17 Boer, 16 Kacang and 17 Boerka respectively. BMP15 gene amplification resulted fragment with the length of 141 bp. Genotyping of BMP15 gene produced three genotypes. The result showed that BMP15 gene found two polymorphic SNP were analyzed by genotype frequency, allele frequency, heterozygosis and equilibrium of genotype in all population was detected by the Hardy-Weinberg equilibrium test (χ2). Sequence analysis results of BMP15 gene showed that there were two mutation between adenine (A) and guanine (G) bases and determination of genotype BMP15 gene produces three genotypes showed that there were GG, GA and AA. In conclusion, there was found the mutation of BMP15 gene in Boer, Kacang and Boerka goats and genetic polymorphism were identified using PCR-Sequencing method.

Abstract

Productivity improvement of forage in suboptimal land can be done in various ways, such as through manure and ameliorant treatment. Manure and dolomite is required by soil on suboptimal land, a combination of both can supply nutrients and improve soil biophysics. The research materials used in this study were B. decumbens, Pueraria phaseloides, manure, and dolomite. Randomized Block Design (RBD) in 3x3 factorial was applied. The dose of manure and dolomite are the first and second factors respectively, each treatment has 3 replications times. Variables measured were biomass production, dry matter production, carrying capacity, and nutrient content of forage. Results showed that the highest (P<0.05) biomass production produced by the 10 t/ha manure and 2 ton/ha dolomite treatment by 1,638.94 g/m2 compared to the other treatments, and the lowest was achieved in the control by 543.75 g/m2. Carrying capacity of B. decumbens and P. phaseloides on 10 ton/ha manure was the highest (P<0.05) by 0.08 AU compared to the other treatments. Super dolomite administration by 1 ton/ha significantly (P<0.05) produced the highest carrying capacity by amount of 0.83 AU. Manure and dolomite administration significantly (P<0.05) improved the nutritional content of B. decumbens and P. phaseloides.

Abstract

The induction mutation using gamma rays is one way to increase the diversity of Bengggala grass (Panicum maximum). Diversity is the main base in selecting to produce varieties of Benggala grass on acid land. The aim of this study is to know the morphological character and genetic diversity of grass that received gamma rays. The research was conducted in the Tenjo district, Bogor which has pH 4.9-5.5 and the content of Al-dd 2.26 c mol/kg with Al saturation of 10.68%. The study started by looking for Benggala grass radio sensitivity, then from radio sensitivity determined radiation treatment dose of 200 Gy, 250 Gy, 300 Gy and 350 Gy. Treatment of radiation dose is acute and fractionated, so there are 8 treatment doses plus control (plants without radiation). The variables measured were plant height, stem height, stem diameter, length of segment, leaf length, leaf width, fresh weight, dry weight, and number of tillers. The results showed that the radio sensitivity of Benggala grass produced in the form of lethal doses (LD) LD 20 and LD50 is 176.83 Gy and 358.23 Gy. By the mathematical equation: Y = 44.22 + 45.91 X Cos (0.0042x -0.07). The morphological character of M1 shows that the radiation dose affects the measured variable. 300 Gy fractionated radiation dose (150 Gy x 2) results in higher fresh weight of the plant. While in the generation of M1V1 radiation dose of 250 Gy produces high fresh forage weight. Medium to high heritability with GVC value (criteria of coefficient of genetic variability) is high enough until high is obtained on the character of the number of tillers, fresh weight and dry weight. So it is possible to do next selection on these three characters.

Abstract

The demand for meat in Indonesia cannot be supplied by domestic cattle production, and so breeder cattle stock are imported from abroad overseas to increase domestic production. A commonly imported breed is Brahman cross bred (Bx). Smallholder farmers have reported a wide range of problems associated with Bx cow reproductive performance. The purpose of this study was to identify changes in the reproductive performance of Bx cows by providing advice to farmers on improved management strategies, such as: maintaining body condition score (BCS) of cow> 3, appropriate estrous detection and weaning at 5- 6 months. This study was conducted from October 2011 – December 2013 by using 189 Bx cows and 151 farmers. The research was conducted in two sub districts of Lamongan district (East Java), Modo and Sambeng. Cattle were fed diets based on crop residues and were supplemented with green feeds, by-products (rice bran) and concentrate during the last 2 months of pregnancy and early lactation. The reproductive performance of cows improved during the study, there were a shorter lactation length/early weaning (reduced from 188 days to 153 days) and improved BCS (from 3.0 to 3.3). The length of postpartum anestrous interval (PPAI) decreased from 198 days to 98 days. Cycling to conception decreased from 75 days to 64 days and days open decreased from 217 days to 118 days over the length of the study. This was associated with improvement in BCS of cows at calving (from 3.0 to 3.3) and a shorter lactation length (reduced from 188 days to 153 days). There was no change in the average birth weight of calves (31.8 kg). There was no change in average weaning weight of calves over the year and average daily gain of calves while suckling 0.7 kg/day. The pre weaning calf mortality rate was decreased during this study (from 13% to 6%). This project demonstrated that Brahman cross cows can successfully be kept by smallholder farmers in Indonesia if appropiate management is used. It can be concluded that improving management, such as maintaining body condition score of cow >3, estrous detection, appropiate mating and weaning at 5-6 months can improve reproduction performance of Brahman cross.

Abstract

Sumbawa horse milk is claimed to cure some diseases such as asthma, hypertension, diabetes and gastrointestinal disorder but its potential bioactive peptide has not been explored. The aims of this study are to evaluate bioactivities peptides from Sumbawa horse milk protein hydrolysate and to analyzethe physio-chemical properties of selected peptides. The milk protein was hydrolyzed by Bacillus thuringiensis protease, the peptide produced were sequential fractionated and then analyzed for antibacterial and antioxidant activities. The peptide fraction <3 kDa was then sequenced using LCMS-MS and the physio-chemical properties of the peptides were analyzed. The result showed that peptides fraction <3 kDa from the 30 min hydrolysis was the most active as antibacterial and more active to Gram negative bacteria.  For antioxidant, scavenging activity of the fraction per µg protein/mL were 83% to ABTS and 31% to DPPH radicals. The values were similar with vitamin C 12.5 µg/mL for ABTS and 14.5 µg/mL for DPPH. Peptide HPYFYAPELLYYANK with molecular weight prediction 1887.92 Da and isoelectric point 7.47 has high therapeutic index prediction (64.75). The result showed that peptides from Sumbawa horse milk hydrolyzed by Bacillus thuringiensis protease was active as antibacterial and antioxidant. Peptide HPYFYAPELLYYANK from fraction <3 kDa was potential as antibacterial.

Abstract

Cellulose from abundant newspaper waste could be transformed into methane through anaerobic fermentation. This research was carried out to compare the gas production including methane between samples containing feces and waste paper mixture as inoculum and substrate, respectively and added with and without BS4 enzyme. The enzyme was produced in Indonesian Research Institute of Animal Produce (IRIAP) by growing Eupenicillium javanicum BS4 in coconut meals. There were three treatments,  i.e., 30% manure (M30); 15 %  manure + 15 % paper waste  (MP 30); MP30 + 3 mL BS4 enzyme equal to 0.42 U/g dry matter (MPE30) The percentage of waste papers addition in feces was calculated on dry matter (DM) basis and every treatment had five replications. Total gas and methane productions were measured weekly, while dry matter losses were determined during 5 week fermentation. Interactions between treatments and incubation time were analyzed using completely randomized design each week. Kind of substrates influenced both total gas and methane productions during incubation time. Both waste papers and enzyme addition enhanced gas production. The highest total gas and methane productions for five weeks incubation were highly significantly observed (P<0.01) in MP30 and MPE30 compared to M30. Addition of enzyme significantly increased total gas and methane productions in the first week. The highest methane and total gas yield/g dry matter were obtained by BS4 enzyme addition. It was concluded that BS4 enzyme is good in accelerating and increasing the transformation efficiency of waste paper and manure mixture for biogas production.
