Abstract

Aflatoxin, which known as toxigenic compound, is a secondary metabolite produced by Aspergillus flavus and A. parasiticus. Aflatoxin is found in both food and feed stuffs, such as: corn and peanut. Aflatoxin standard is needed in every research of aflatoxin contamination. But it is rather difficult to get. It is imported, high costs, and take times. The aim of the research is to assess the potential local isolate of A. flavus to producing aflatoxin that can be used to be the alternative aflatoxin standard. Local mold of A. flavus FNCC 6122 and FNCC 6109 are got from PAU University of Gadjah Mada. Isolate was enriched on PDA medium for 5 days and move to corn medium of corn+peanut combine medium for 10-15 day at 25ºC. The variables was the content of AFB1 by ELISA test. The result is shown that isolat FNCC 6122 produced higher AFB1 than isolate FNCC 6109. The combine of corn and peanut medium stimulated FNCC 6122 to produce higher AFB1 and has potency to be the candidate of standard aflatoxin. In conclusion, the peanut addition on the medium would initiate increasing of the aflatoksin B1 level.

Abstract

The research aimed to investigate the effect of different planting space on the seed production of Brachiaria brizantha cv. MG 5.This study used three dimensions of spacing: 75 x 75 cm, 100 x 100 cm, and 150 x 150 cm. The seed was germinated before planted on the 3 x 3 m plot with three replications. Fertilization was performed twice at the age of 30 and 90 days with NPK fertilizer 400 kg ha-1 and given the same amount of water. The variables observed were the plants’ height, length, number of tiller, inflorescence, raceme, spikelet, the seed purity, the seed production (kg ha-1), and viability. The data obtained were analyzed statistically by using the Completely Randomized Design (CRD), and if any difference existed, it was continued with Duncan's new multiple range test. The results showed that the different planting space was significant (P<0.05) to the seed production of Brachiaria brizantha cv. MG5., which was the seed production at 75 x 75 cm spacing was 206.43 kg ha-1, 100 x 100 cm was 354.43 kg ha-1, and 150 x 150 cm was 128.87 kg ha-1. The highest seed production was resulted in planting space of 100 x 100 cm that was 354.43 kg ha-1.

Abstract

This research aimed to observe the interaction of methionine-cysteine amino acid supplementation to decrease the effect of aflatoxin B1 (AFB1) on diet against production performance of broiler chicken. A number of 240 mixed sex broiler chickens were treated in 9 treatments by factorial design 3 x 3 with methionine-cysteine amino acid (M+C) (75,100, dan 125%) factors and AFB1 levels (0, 200, dan 400 ppb). Variables observed were: Weight gain, feed consumption, and feed conversion ratio (FCR). The results showed that increased AFB1 content in diet from 0 to 400 ppb increased chicken body weight (P <0.05) in each age group. The high body weight was balanced with high feed consumption along with increased nutrient needs, mainly sulfuric amino acid (M+C) as the precursor of glutathione to eliminate toxic through conjugation reactions. The interaction effect was firstly occurred between M + C and AFB1 treatment (P <0.05). Meanwhile increased supplementation of M + C from 75 to 125% caused decreased feed consumption in each age group of chickens, but increased AFB1 levels further increased feed consumption (P<0.05). The interaction effect between the level of M + C and AFB1 contamination in diets on feed consumption were seen in 21-day-old chickens (P<0.05). FCR was also increased (P <0.05) with the reduction of M + C content in diet at 7 days old. The effect of AFB1 on diet and interaction between M + C and AFB1 on chicken FCR in this study was not significant in all age groups. It can be concluded from the current study that supplying methionine-cystine amino acid with 75, 100 and 125% in AFB1 contaminated diet of 0, 200 and 400 ppb improves the performance of broiler chicken production.

Abstract

This study was done to determine the effects of bale sizes of bio-ammoniated rice straw on its nutrient quality and in vitro digestibility. Rice straw were bio-ammoniated by adding 2 g urea and 1 g probiotic/kg DM. By following a completely randomized design, rice straw was baled in 3 different weights (15, 25, and 35 kg) with six replications for each treatment, and then stored for 3 weeks. In the end of the week 3, bales were opened, aired, and then sampled for proximate analysis (dry matter, organic matter, crude protein, and crude fiber) and digestibility by in vitro gas production method. Using analysis of variance method, the proximate data showed that greater the bales size (15, 25, and 35 kg) increased crude protein (7.59, 7.86, and 9.95%, respectively; P<0.05) and decreased crude fiber contents (24.1, 22.1, and 18.8%, respectively; P<0.05). By increasing the size of bales also increased a, b, and c fractions (-0.79, 0.26, and 0.82 mL/100 mg DM; 20.2, 18.2, and 17.6 mL/100 mg DM; 0.012, 0.014, and 0.019 mL/h, respectively; P<0.05) as well as gas production (11.4, 11.5, and 13.8 mL/100 mg DM, respectively; P<0.05). It can be concluded that packing bio-ammoniated rice straw in 35 kg bale is the most effective way in increasing nutrient quality and digestibility of rice straw.

Abstract

This study aimed to determine the chemical composition and gas production based on fermentation in the rumen of nine types of forage tropical feed commonly used in Indonesia. The forages used in this study were: mahogany leaves (Swietenia mahagoni L. Jacq.), tayuman leaves (Bauhinia purpurea), bamboo leaves (Bambusa arundinaceae), canary leaves (Canarium indicum L.), tea leaves (Camellia sinensis), ketapang leaves (Terminalia catapa L.), lamtoro leaves (Leucaena leucocephala), tehtehan leaves (Duranta repens), and turi leaves (Sesbania grandiflora). Measurements of in vitro gas production were carried out at 10 observation points (2, 4, 6, 8, 12, 16, 24, 36, 48, 72 hour). Tannin activity was measured for each sample at observation points using measurements of gas production divided into three groups with modified levels of polyethylene glycol (PEG), ie samples without PEG (P1); sample + PEG in the amount of 200 mgDM (P2); and PEG + samples of tannins contained in each forage based on literature studies (P3). Data were analyzed for a variance by following the factorial completely randomized design (CRD) pattern. Statistical analyzes were performed on all data by following the general linear procedure in PROC GLM from SAS. The data obtained were analyzed for variance at the 5% significance level. The results of gas production calculations showed that crude protein (CP) from each forage ranges from 5.75 - 22.37% where the highest CP was owned by turi leaves (S. grandiflora). The content of crude fiber (CF) ranged from 5.30 - 20.93%. The most optimal measurement of gas production was in the sample given PEG in the amount of 200mg/kg with a significant difference (P<0.05). The higher of the tannin content contained in the forage, the lower of gas produced. Measurement of tannin content showed that condensed tannin content varied from turi leaves by 0.20% to the highest in mahogany leaves by 8.60%. The addition of 200 mg/100mgDM of PEG optimizes the rate of forage gas production, especially for grass plants (gramineae).

Abstract

Indonesia's annual beef consumption is experiencing a steady rise. In 2021, the per capita beef consumption amounted to 2.56 kg per person per year, resulting in a total of 696 million kilograms consumed across the country. This quantity is equivalent to the slaughtering of approximately 3.98 million cattle annually. With the increasing growth of the feedlot industry, cattle farmers, including feedlot operators, have the opportunity to enhance the value of agricultural companies in Indonesia by utilizing local feedstuffs. The objective of this study was to assess the suitability and nutritional value of indigenous feed sources for beef cattle in Indonesia. The research utilized feedstuff varieties and characteristics sourced from feedlots spanning since 2012-2021. The employed methodologies encompassed surveys, interviews, and questionnaires. This research involved the collection of both primary and secondary data. The potential and quality of local feedstuff were described using descriptive analysis. This research showed that eight types of local feedstuff could be categorized as energy sources including dehydrated cassava chips with a total digestible nutrients (TDN) value of 84.2% and bran pollard with a TDN value of 66.6%. The fiber sources consisted of corn cob (37.7% crude fiber), coffee husk (38% crude fiber), cocoa bean shell (20% crude fiber), tapioca solid waste/onggok (22% crude fiber), and palm kernel meal (22.1% crude fiber). The protein source consisted of copra meal with a protein content of 22.4%. The physical test most frequently inspected the feed color (18.1%) and odor (18.1%). Moisture examination (24%) was the most frequently used of proximate analysis was employed to identify the chemical composition. In conclusion the existence of eight local ingredients which were categorized into three different types: energy source, protein source, and fiber source commonly used in the concentrate formula for beef cattle feedlots in Indonesia.
