The potential of frozen rumen fluid for ruminant feed evaluation using in vitro gas production technique

The aim of this study was to determine the potential of frozen rumen fluid (RF) for ruminant feed evaluation using in vitro gas production (IVGP) technique. This study used a factorial randomized block design with a 3 × 3 × 3 pattern, consisting three feeding regimes varying in forage to concentrate proportion, namely 20%:80% (feed A), 40%:60% (feed B), and 60%:40% (feed C), respectively; three storage time (2, 11, and 19 days); and RF from 3 breeds of indigenous cattle, namely Bali, crossbred Ongole and Madura cattle as groups. The results showed that the effects of feeding regimes, inoculum source, or storage time on total gas production, potential of gas production, rate of gas production, dry matter and organic matter degradability. Based on the results, it can be concluded that frozen RF may be used as inoculum source for feed evaluation using the IVGP technique and hence it supports the previous findings reported in the literature. Considering that the effects of different feeds, inoculum sources, and storage times gave the specific values, it is advisable that to use RF from slaughtered animals should be taken from the same breed to allow accurate comparison for feed evaluation using IVGP technique.

Potential environmental impact of bromoform from Asparagopsis farming in Australia

To mitigate the rumen enteric methane (CH4) produced by ruminant livestock, Asparagopsis taxiformis is proposed as an additive to ruminant feed. During the cultivation of Asparagopsis taxiformis in the sea or in terrestrial based systems, this macroalgae, like most seaweeds and phytoplankton, produces a large amount of bromoform (CHBr3), which may contribute to ozone depletion once released into the atmosphere. In this study, the impact of CHBr3 on the stratospheric ozone layer resulting from potential emissions from proposed Asparagopsis cultivation in Australia is assessed by weighting the emissions of CHBr3 with the ozone depletion potential (ODP), which is traditionally defined for long-lived halogens but has been also applied to very short lived substances (VSLSs). An annual yield of ~3.5 × 104 Mg dry weight (DW) is required to meet the needs of 50 % of the beef feedlot and dairy cattle in Australia. Our study shows that the intensity and impact of CHBr3 emissions varies dependent on location and cultivation scenarios. Of the proposed locations, tropical farms near the Darwin region are associated with largest CHBr3 ODP values. However, farming of Asparagopsis using either ocean or terrestrial cultivation systems at any of the proposed locations does not have potential to impact the ozone layer. Even if all Asparagopsis farming was performed in Darwin, the emitted CHBr3 would amount to less than 0.016 % of the global ODP-weighted emissions. The remains are relatively small even if the intended annual yield in Darwin is scaled by a factor 30 to meet the global requirements, which will increase the global ODP-weighted emissions by 0.48 %

Evaluation of potential and local forages nutrition as ruminant feed-in Payo Agro-Tourism Area, Solok City, West Sumatera, Indonesia

This study aims to evaluate local forage’s potential and nutritional content in the Payo agro-tourism area of Solok, West Sumatra, Indonesia, to be used as a ruminant feed. This study used a survey method by taking a sample of the forage that grows a lot in the area and then analyzed its nutritional content. The nutritional content analyzed were dry matter, ash, crude protein, crude fiber, crude fat, calcium, and phosphorus minerals. At the same time, the TDN value and the extracted material without nitrogen were calculated based on the formula. The results showed that 12 types of forage have the potential as ruminant feed, namely Panicum maximum, Tithonia diversifolia, Gliricidia sepium, Digitaria sp, Centrocema pubescens, Calliandra calothyrsus, Stachytarpheta jamaicensis, Bidens pilosa, Ipomea triloba, Micania Scandens, Asystasia gangetica, and corn straw. This study shows that Calliandra calothyrsus has the highest crude protein content, and Corn straw contains the lowest crude protein. The highest and lowest TDN values were Gliricidia sepium and Panicum maximum, respectively. Through the linear programming program, these 12 plants can be formulated into 4 ration formulations with 58% TDN and 15-16% crude protein.

Labelling of corn as forage for ruminants using isotope 15N

In vitro and in vivo testing for ruminant feed efficiency can be done by utilizing the stable isotope Nitrogen-15 (15N) as a tracer. Feed can be traced by labeling the forage using isotope 15N. Feed crops are labeled using an isotope 15N-enriched fertilizer. The critical thing to note is to know the content of isotopes 15N in the part of forage feed plants that have been labeled. This research aims to know the effect of urea fertilizer on the percent of atom excess 15N on corn. Corn are labeled using urea enriched with isotopes 15N in the form of urea fertilizer (10% excess atom 15N) with different doses (0-200% recommended urea dose). As a control used corn plants given urea fertilizer is not labeled 15N. The results showed that corn forage feed was successfully labeled and correlated with the dose of fertilizer. The range of atom excess 15N was 4.28 – 6.99% in corn forage. Biomass production showed no significant difference between the dose of fertilization and control, but neither protein content. Based on data, the corn forage can be used for further testing.

Utilization of Tithonia diversifolia as Ruminant Feed

<p>Forage is an important component in raising ruminants. Limited land specifically for forage cultivation is a big challenge in providing forage. <em>Tithonia diversifolia</em> is a promising species used as feed for ruminants because it is easy to grow in various places without being cultivated, such as on roadsides or as fences. This paper aims to give information about <em>Tithonia diversifolia</em> and its cultivation, production, nutritional value and its utilization as forage for ruminant. This plant can be propagated vegetatively and generatively. The spread of seeds can be carried by vectors such as humans, livestock, water currents and wind. <em>T. diversifolia</em> plants have several advantages: fast growing, high production, high crude protein content, resistance to high cutting frequencies and tolerance to acidic soils. Apart from these advantages, this plant also has some weaknesses because it contains several secondary compounds which may affect rumen fermentation. This weakness can be overcome by addition of feed aditive, charcoal or by processing it into silage. <em>T. diversifolia</em> has been used as feed for small and large ruminants either as single or mixed feed with concentrates and other forages with relatively high digestibility. The dry matter consumption of <em>T. diversifolia</em> reaches nearly 600 g/h/d when given as single feed to goats. However, recommended feeding level is 30% of total ration. </p>

Proximate, microbial and mineral compositions of Millet Pennisetum gluacuum L. and sorghum bicolor compounded straw feed for ruminant

The study was aimed for the production and determination of the proximate, microbiological and mineral compositions of Millet Pennisetum gluacuum L. and Sorghum bicolor compounded straw feed for ruminant production. The result revealed a pH 5.791 which is suitable for fibre in the feed and promote chewing and rumination processes in the rumen, low percentage moisture content of 1.37 was recorded due to high drying in the field, high percentage fat and crude protein of 4.67 and 6.97 respectively this was as a result of the inclusion of groundnut cake as source of protein and fat in the feed, percentage digestible protein was 3.58, crude fibre value of 27.56 which satisfied the 18% requirement in the diet of ruminants, percentage carbohydrate was 54.2, and estimated energy value (Kcal) 286.95. Microbiological analysis showed a total plate count of 5 x10-4 cfu/g, Mould count of 1 x10-3 cfu/g, while Yeast, Staphylococcus, Coliform, Shigella, Salmonella and Escherichia coli count were not detected respectively. Mineral composition of sorghum and millet Pennisetum gluacuum compounded straw feed showed the presence of Fe, Na, K, Mg, Zn, Cu Mn, and Cr as 120.4189mg/kg, 570.9844 mg/kg, 227.1493 mg/kg, 568.2669 mg/kg, 12.9195mg/kg, 14.0666mg/kg, 62.9926mg/kg respectively and 18.584 mg/kg while Ni and Pb were not detected in the formulated ruminant feed.

Effect of Napier grass ensiled with or without inclusion of soy waste on the performance of growing goats

Utilization of soy waste as a ruminant feed is low due to storage problems and transportation costs.An experiment was carried out with fifteen goats to assess the feeding value of Napier grass(Pennisetum purpureum) ensiled with or without soy waste. Grass ensiled without soy waste wastermed as NM silage, while grass ensiled 30% soy waste (w/w) was termed as NMS silage. In bothsilages, 1.0% molasses (w/w) were incorporated to enhance the fermentation process. After 2months of ensiling, three diets were formulated and assigned to one of three groups: (i) Napier grassad libitum plus 1% pellet of body weight (BW) on a dry matter (DM) basis (T1), (ii) NM silage adlibitum plus 1% soy waste of BW on a DM basis (T2), and (iii) NMS silage ad libitum (T3). TheNMS silage showed a lower pH (4.04 vs. 4.64) than NM silage. The NMS silage exhibited higherproportions of DM, organic matter (OM), and crude protein (CP) compared to NM silage. Animalsreceived T1 diet showed higher (p<0.05) DM, OM and neutral detergent fibre intake compared tothe animals received T2 and T3 diets. However, animals received T2 diet showed higher CP intakethan the animals received T1 and T3 diets. Similarly, animals received T2 diet showed higher(p<0.05) BW gain (49.4 vs. 16.5 g/d) than the goats fed T3 diet. In conclusion, the T3 diet mayhave limited goat performance, which needs further study to improve the quality of silage.

Sabun Kalsium dari PFAD untuk Pakan Ruminansia: Kualitas PFAD Sebagai Sumber Asam Lemak Bebas

Abstrak. Dalam rangka meningkatkan komoditas susu di Indonesia, pemerintah menargetkan sapi perah lokal harus mampu menyuplai 41% produksi susu dalam negeri pada 2022. Salah satu cara untuk menaikkan produksi susu sapi adalah memberikan suplemen pakan berupa sabun kalsium. Sabun kalsium telah banyak digunakan di luar negeri, namun tidak di Indonesia, untuk menaikkan produksi susu sekaligus fertilitas ruminansia. Sabun kalsium dapat dibuat melalui reaksi fusi termodifikasi antara Palm Fatty Acid Distillate (PFAD) sebagai sumber asam lemak bebas dengan sumber kalsium. Penelitian ini mengevaluasi pengaruh jenis PFAD terhadap kualitas produk sabun kalsium. PFAD yang digunakan berasal dari beberapa industri pengolahan kelapa sawit di Indonesia, yaitu Kabupaten Sidoarjo, Kabupaten Bekasi, Kota Bekasi, dan Kabupaten Pelalawan dengan rentang angka asam 195–221 mg KOH/g sampel. Produk sabun kalsium yang dihasilkan kemudian dianalisis nilai angka asam untuk menguantifikasi kualitasnya. Keempat produk sabun kalsium secara keseluruhan memiliki angka asam di bawah 1 mg KOH/g sampel. Rendahnya angka asam pada produk membuktikan bahwa keempat sumber PFAD dapat digunakan sebagai bahan baku pembuatan sabun kalsium dengan kualitas baik. Kata kunci:angka asam, kalsium oksida, PFAD, pakan ruminansia, sabun kalsium. Abstract. Calcium Soap from PFAD for Ruminant Feed: Quality of PFAD as a Source of Free Fatty Acids. In order to increase the milk commodity in Indonesia, the government targets local dairy cattle to be able to supply 41% of domestic milk production by 2022. One way to increase the production of cow's milk is to provide a dietary supplement in the form of calcium soap. Calcium soap has been widely used overseas, but not in Indonesia, to increase milk production as well as ruminant fertility. Calcium soaps can be made by modified fusion reactions between PFAD as a source of free fatty acids with a calcium source. This study evaluated the effect of PFAD type on the quality of calcium soap products. PFAD used were obtained from several palm oil processing industries in Indonesia, namely Sidoarjo regency, Bekasi regency, Bekasi city, and Pelalawan regency with the acid number 195–221 mg KOH/g sample. The resulting calcium soap product is then analyzed for the acid number to quantify its quality. The four calcium soap products had an acid number below 1 mg KOH / g sample. The low acid number in the product indicates that the four sources of PFAD can be used as raw material for producing calcium soap with good quality. Keywords: acid value, calcium oxide, calcium soap, PFAD, ruminant feed.

Sosialisasi Pemanfaatan Limbah Pertanian Sebagai Bahan Pakan Ransum Ternak Ruminansia Pada Kelompok Ternak Sapi Di Desa Lampakuk Kecamatan Cot Glie Kabupaten Aceh Besar

Ransum adalah gabungan dari beberapa macam bahan pakan ternak yang disusun dengan formulasi tertentu untuk memenuhi kebutuhan nutrisi ternak. Bahan-bahan pakan penyusun ransum yang tersedia di wilayah Lampakuk Kabupaten Aceh Besar seperti: limbah batang jagung, bonggol jagung, dedak padi, kulit kakao, bungkil kelapa, daun ubi jalar dan jerami padi. Bahan-bahan pakan tersebut, selama ini belum dimanfaatkan oleh peternak sebagai bahan – bahan pakan penyusun ransum ternak ruminansia. Kegiatan sosialisasi ini dihadiri oleh 15 orang peternak serta dilakukan dengan metode pemberian materi, diskusi dan praktek langsung penyusunan ransum. Hasil yang diperoleh menunjukkan antusias peternak sapi dalam memanfaatkan limbah pertanian sebagai bahan pakan penyusun ransum menjadi meningkat, sehingga memngkinkan untuk meningkatkan jumlah ternak yang dipelihara. Jika selama ini hanya mengoptimalkan rumput-rumputan dan hijauan sebagai makanan ternak, maka dengan kegiatan sosialisasi ini meningkatkan pengetahuan dan wawasan peternak dalam memanfaatkan limbah pertanian sebagai ransum makanan ternak ruminansia.Kata kunci : Limbah Pertanian, Bahan Pakan, Ransum, Ternak Ruminansia.ABSTRACTThe ration is a combination of several kinds of animal feed ingredients which are arranged in a certain formulation to meet the nutritional needs of livestock. The feed ingredients that make up the ration available in the Lampakuk area, Aceh Besar District, are: corn stalk waste, corn cobs, rice bran, cocoa husk, coconut cake, sweet potato leaves and rice straw. These feed ingredients, so far have not been used by breeders as feed ingredients for ruminant rations. This socialization activity was attended by 15 farmers and was carried out using the method of providing material, discussion and direct practice of preparing rations. The results obtained show that the enthusiasm of cattle farmers in utilizing agricultural waste as feed ingredients for rations has increased, so that it is possible to increase the number of livestock kept. If so far it has only been optimizing grasses and forages as fodder for livestock, then this socialization activity will increase the knowledge and insight of farmers in utilizing agricultural waste as ruminant feed rations.Keyword :Agricultural Waste, Feed Ingredients, Ration, Ruminant Livestock.
