Abstract

The land as the ecological base of the farming system is one of the important factors for the farmers. The wrong management of the soil may cause the critical farming land. An experiment had been conducted to study the possibility of livestock development which also could improve the soil fertility in the critical land. Survey method was used in this research on the critical land decided by the Board Government of Banyumas Regency, namely, Ajibarang, Pekuncen, Gumelar, Wangon, and Lumbir Districs. The sample of villages was determined from the five districts, i.e., 50% of total villages of each district). Determination of villages were made by a Stratified Random Sampling on the basic of evaluation result both from the stand point of natural physic and from the standpoint of socio-economic. Data were collected directly and by interview supported with the previously prepared questionnaires. The result showed that all of the critical lands from five districts in Banyumas Regency were still capable to receive the livestock and could be utilized as the land of sheep and goat. The average PMH was 1291,51 ST and PMK (except Ajibarang) was 326,61 ST, although the TDN (3,1 kg/kg BK) and CP (8,8% DM) were low. It could be concluded from this research that the critical land area in Banyumas Regency was capable to make sheep and goat livestock development because the area condition was open with the area opening index of 3.366.

Abstract

Abstract. The aim of this research was to find the optimum level of substitution of fresh Napier Grass with Spent Rice Straw Compost (SRSC) on rumen metabolism products. Two male cattle breeds consisted of indigenous cattle (Ongole Crossbred = OC) with average body weight of 78.48±7.69 kg  and Fries Holland Crossbred (FHC) with body weight of 83.93±17.67 kg were kept in individual cages of 1x1.2 m and they were given  four kinds  of Napier Grass subtituted with SRSC of 0, 25, 50 and 75 percent of forage dry matter. Therefore, factorial experiment of 2x4 was used in this research. The dry matter ratio of forage and concentrate was maintained at 50:50% with total dry matter intake 3% of body weight. Total Volatil Fatty Acid (VFA) production were influenced by the breed of cattle and the body weight, but there was no significant effect of breed on the N-NH3.  Both average of VFA (122.92±3.22 mM/l) and N-NH3 (4.14±0.4 mM/l) were still in the optimum range for rumen micoorganisme activities. Regression analysis showed that the digestibility of crude fiber had same pattern with acetate (C2), propionate (C3), butirate (C4), and valerate (C5). It can be concluded that SRSC can be used to substite fresh Napier Grass up to 75 percent of forage dry matter  in the diets of male cattle both OC and FHC. Keywords : Spent compost, Volatile Fatty Acid, Nitrogen Ammonia Abstrak.

Abstract

The objective of current study was to evaluate the impact dietary non-fibrous carbohydrate ( NFC) and ruminally degradable intake protein (DIP) concentration have on ruminal fermentation , nutrient digestion and performance of local sheep. The animal had a mean of  liveweight 19.80 ±1.55 kg. four diets ,arranged in a 2x2 factorial ,were formulated to contain either 40 or 50 % NFC and 50 or 60 % of dietary crude protein as DIP .dietary DM contained 25 % Indonesian field grass and 75 % concentrate. Solvent –extracted or formaldehyd  2 % -treated soybean meal were used to alter DIP and corn or soybean hulls to alter NFC level. Percentage of  energy and NDF digestion was similar ( p<0,01) as DIP level decreased in the diets. The soybean hulls was fermentable and total VFA concentration in the rumen increased ( p<0.01), but N-NH3 concentration was decreased ( p<0.01) as DIP level decreased in the diets. Daily live weight gain ( 146.29±25.84 g) and body composition ( fat, water , protein and mineral) was similar ( p<0.05) among diets. The preponderance ruminal fermentation ,nutrient digestion and performance of local sheeps did not be improved by sincronization of energy and nitrogen release but may more likely be limited by either energy or nitrogen alone.

Abstract

Biomasa of agricultural residues are potensial as ruminant feeds. However due it is low palatability, digestibility and nutritive value limited their use. In order to improve their use, treatment need to be applied. Biological treatment by using microba seems to be an alternative because of their capability with no pollution problems. The first experiment aims to select the microorganism which have a potensial to degrade the crude fiber, based the production of reduction sugar. The second experiment aims to improve the protein and amino acid on rice straw, cassava, waste, and rice husk, by inoculated the starter of Candida utilis and or Sacharomyces cerevise. The second experiment has been conducted on Animal Nutrition and Feed Laboratory, Faculty of Animal Husbandry UNSOED for eight month Fermentation trial has been done in semi solid media, by the method of Kjic (1964), in Batch System, Variables measure were: (1) reduction sugar, (2) cellulose, (3) protein, (4) amino acids, (5) cellulase activity, (6) essensial mineral and (7) energy. Based on the all variables measured that were conclused that the quality of  rice straw can be improved by mixed culture of  T, viride – S. cerevise, the rice husk by A. niger – C. utilis, T. viride – C. utilis and A. niger – S cerevise while for cassava waste by  A. niger – S. cerevise and A. niger – C. utilis  (Animal Production 1(1) : 10-16 (1999). Key Words: Waste Product, Energy, Microorganism

Abstract

Abstract.  On farm level, the price of milk is affected by its fat content. On the other hand, improving milk quality by the use of better ration economically is not feasible. The problem is how to find an appropriate, easily found, relatively cheap and efficient ration for producing better quantity and quality of milk. An experimental research was conducted using Saccharomyces cerevisiae yeast in lactating dairy cows ration, in a  4x4 Latin Square Design, with animal trial as column and trial period as row. Each trial period consisted of 14-day preliminary and 7-day trial period (collection period). The treatment to be tested were four levels of yeast addition, namely : 0, 5, 10 and 15 g/cow/day. The variables measured were daily milk production (4% FCM) and milk composition (solid non fat, fat, protein, lactose). The result showed that the addition of yeast had no significant effect on milk production and milk composition, but tended to increase milk fat in which the highest fat content of 5.13 % was achieved when 8.5 g/cow/day was suplemented. The average milk production, solid non fat, lactose, fat, and protein were 9.55 kg/day, 8.70%, 3.99%, 4.50% and 0.13%, respectively. Based on all measured variables, it can be concluded that the addition of yeast Saccharomyces cerevisiae up to 15 g/cow/day to lactating dairy cows ration did not effectively improve milk production and milk composition. Key words: yeast addition, milk production, milk composition. Abstrak.  Penentuan harga susu di tingkat peternak sangat dipengaruhi oleh kadar lemak susu. Perbaikan komposisi susu dengan peningkatan kualitas pakan sulit dilakukan, karena tidak ekonomis. Oleh karena itu perlu dicari ransum yang murah, mudah didapat dan efisien untuk meningkatkan produksi dan komposisi susu. Suatu penelitian telah dilakukan dengan menggunakan ragi Saccharomyces cerevisiae dalam ransum sapi perah laktasi. Penelitian dilaksanakan dengan metode eksperimental, menggunakan Rancangan Bujur Sangkar Latin 4x4. Hewan percobaan sebagai kolom dan periode percobaan sebagai lajur. Setiap periode percobaan terdiri atas 14 hari masa preliminari dan 7 hari percobaan (masa koleksi). Perlakuan yang diuji adalah 4 taraf penambahan ragi Saccharomyces cerevisiae : 0, 5, 10, dan 15 gr/ekor/hari. Peubah respon yang diamati adalah produksi susu harian (4% FCM) dan komposisi susu (BKTL=Bahan Kering Tanpa Lemak, lemak, protein dan laktosa).  Hasil penelitian menunjukkan bahwa penambahan ragi tidak berpengaruh nyata terhadap produksi 4% FCM (Fat Corrected Milk) maupun komposisi susu, tetapi cenderung meningkatkan lemak susu dan mencapai kadar tertinggi 5,13% pada penambahan ragi 8,50 g/ekor/hari. Rataan produksi susu 9,55 kg/hari, BKTL (Bahan Kering Tanpa Lemak) 8,70 %, laktosa 3,99%, lemak 4,50% dan protein 0,13%. Berdasarkan semua peubah respon yang diukur dapat disimpulkan bahwa penambahan ragi Saccharomyces cerevisiae sampai 15 gr/ekor/hari belum berhasil memperbaiki produksi dan komposisi susu. Kata kunci : penambahan ragi, produksi susu, komposisi susu.

Abstract

The waste of the broiler processing (feather) is a potential source for animal feed. However the presence of keratins cause limited of feather use. Before using, therefore, feather must be treated to hydrolyze cysteine disulfide bound dominating keratins protein. Enzymatic (biological) treatment using microbes will produce specific feather hydrolyzed and does not have negative impact on environment. The research objected to get the microbes which degradated selected keratins, improve protein quality of feather meal and find out the best ration formulation true in vitro the basic information to formulate in vivo ration. The research has been done in Laboratory of Animal Feedstuff Faculty of Animal Science UNSOED for eight months. Fermentation trial was done on liquid media with bath system. In vitro trial used of Tilley and Terry methods with parameter observe was dry matter digestibility, organic matter digestibility, protein degradation, total VFA and solubility in pepsin. Based on all parameter, on fermentation trial with Bacillus licheniformis decides broiler chicken feather had good prospect to be developed on feed protein source. In vitro trial recommended ration with formulation of fermented feather meal concentrate (15 percent), soybeans meal (5 percent), rice bran (20 percent), molasses (4 percent), mineral mix (1 percent), with forage: concentrate ratio 40 : 60 could be used as in vivo ration.

Abstract

Generally, sheep are capable to cosume the forage about 90 percent of their dry matter requirement.  In Indonesia, sheep generally accumulated in low land area, so that the requirement to be supply by dried field grass only. An experiment have been conducted at the Experimental Farm, Faculty of Animal Science, General Soedirman University.  Twenty seven male sheep were used in a Completely Randomized Blok Design of three replication.  The factors tested were : three levels of dried field grass at: 0, 21.25 and 42.50 percent dry matter of ration.  The variables measured were: (1) crude fibre digestion coefficient; (2) Rumen metabolism product: volatile fatty acids, espencially acetate (C2), propionate (C3), butyrate (C4), and valerate (C5). The digestion trial was carried out by the Total Collection methods and the production of individual volatile fatty acids were determined by chromatography technique.  The analysis of covariance shown, that there was no significantly effects of treatment tested upon the crude fibre digestion coefficient (P>0.005), but there were a highly significant effect ( P<0.001) upon the production of acetate ((C2) and propionate (C3).  The relationship of ceude fibre digestion coefficient with all of the rumen metabilism product were shown to be same, in cubic form.  Based on the crude fibre digestion coefficient and the production of individual volatile fatty acid, it was found that dried fields grass can be used up to 42.50 percent of ration dry matter for male sheep.

Abstract

Various chemical treatments were conducted to increase the utilization of rice straw as feed for ruminant animals. Various sources of protein, minerals and energy should be added to improve the nutritive value of feeds.  Two experiments were conducted in this study. The objective of the first experiments was to study the effect of chemical treatment on the ruminal fermentation products in cattle.  Unconventional alkali treatment made from filtrate of a 10% rice hulls ash solution enriched with urea and minerals (treatment 1) increased volatile fatty acid (VFA) production, ammonia nitrogen (NH3-N) and rumen microbial protein synthesis (MPS).  The maximum values of NH3-N production and rumen microbial protein synthesis were reached at 4 hours after incubation, while VFA was reached at 6 hours. The second experiment was conducted to study the increase of nutritive value of rice straw previously treated in experiment 1 through supplementation with various protein sources.  Protein sources from the residues of vegetative oil production such as coconut, peanut and soybean showed higher responses compared to soy-sauce making residue and tofu making residue. The protein effluent production was highest (2.19 g/d) at a VFA/NH3-N ration of 37.74     (r = 0.912).  It can be recommended that   protein sources from agro-industrial wastes can be used to increase the nutritive value and utilization of rice straw as ruminant feed.

Abstract

Suatu  penelitian  telah dilakukan untuk  mengevaluasi peningkatan kualitas pakan konsentrat pada penggemukan sapi jantan Holstein dengan enzim selulase komplek terhadap metabolisme rumen dan parameter darah.  Dua belas ekor sapi jantan Holstein dengan umur 12 bulan dibagi dalam tiga kelompok berdasarkan bobot awal dalam Rancangan Acak Kelompok digunakan dalam penelitian ini. Sebagai perlakuan adalah pakan A, B, C dan D.  Pakan A adalah kontrol yang tersusun atas rumput gajah, dedak padi, bungkil biji kapas, dedak sorgum, ampas tahu, onggok dan mineral mix dengan komposisi (%BK) berturut-turut adalah 30; 18; 17,5; 23; 4,5; 6 and 1.  Pakan B, C dan D mempunyai bahan dan komposisi seperti pakan A, tetapi dedak padi pada B, bungkil biji kapas pada C dan baik dedak maupun bungkil biji kapas pada D disuplementasi dengan enzim celulase 1,5 g kg-1 BK 24 jam sebelum pemberian pakan. Proporsi propionat (C3) cenderung (P>0,05) meningkatbila dedak padi disuplementasi dengan enzim  (B) dan sebaliknya pada (C).  Oleh karena itu, efisiensi energi juga cenderung meningkat pada sapi yang diberi pakan B. Tidak terjadi perberdaan yang nyata dari penambahan enzim selulase terhadap N-NH3 rumen dan cenderung tinggi pada C dan D. Penambahan enzim pada bungkil biji kapas cenderung menekan plasma urea walaupun kandungan protein pada pakan ini tinggi. Glukosa darah berturut-turut untuk pakan A, B, C dan D adalah 83,15, 88,25, 82,30 and 88,60 mg/L. Penambahan enzim pada bungkil biji kapas cenderung menurunkan glukosa darah pada pakan C. Disimpulkan bahwa penambahan enzim selulase pada dedak padi tidak mengganggu metabolisme rumen dan cenderung untuk memperbaiki energi efisiensi.
