Abstract

The urinary excretion of purine derivative (PD), which consists of allantoin, uric acid, xanthine and hypoxanthine, was used to estimate Microbial Nitrogen (MN) supply on sheep given oaten hay as basal diet supplemented either with faba beans (faba) or barley fortified with urea (barley-urea). Three growing wethers, with average body weight of 43 ± 2.29 kg, were randomly assigned to one of three experimental diets, i.e. oaten hay without supplement (C), diet C + barley-urea (CB), and diet C + faba (CF), according to latin square design (3 x 3). Results of the experiment indicated that PD excretion for C was lower (P = 0.07) than that of CB and CF (2.84 vs 6.08, 7.67 mmol/d). Absorbed PD and estimation of MN supply for C was less (P = 0.07) than those of CB and CF, namely 1.26 vs 6.64, 8.80 mmol/d and 0.91 vs 4.8, 6.30 g N/d respectively. However, the efficiency of MN synthesis was similar, whether the calculation was based on digestible organic matter fermented in the rumen, DOMR (g MN/kg DOMR, P = 0.20) or based on N intake (g MN/g N intake, P = 0.40). In conclusion, supplementation of oaten hay with different protein supplements may improve the estimation of microbial N supply in the growing sheep but both supplements gave similar results on the estimation of MN supply.

Abstract

A common approach for improving the nutritive value of low quality roughages and crop by-products is by pre-treatment or processing either physical, chemical, or biological treatments. Microwave radiation is one type of physical treatment that could be used to treat low quality roughages. Research was carried out to investigate  the effects of microwave radiation on the rumen degradation characteristics of barley straw obtained from two different stages of maturity. The experiment was run factorially based on completely randomized block design. The first factor was stage of maturity, straw cut during the soft elongation time (C1) and during the harvest time (C2). The second factor was levels of microwave radiation times (MWRT) (T0 = control, without MWR; T1 = MWR for 1 minute, T2 = MWR for 2 minutes). The results indicated nutritive values of barley straw obtained from C1 sampling time were significantly better than that obtained from the C2 sampling time in terms of a higher rumen degradation rate and a much greater total potential rumen degradability. In contrast, MWR did not have significant effects on the rate of degradation and total potential degradability of straw in the rumen. Key Words: Microwave Radiation, Barley Straw, Rumen Degradability

Abstract

Rapid and extensive degradation of faba beans (Vicia faba) by ruminal microbes can result in substantial and undesirable N loss from the rumen. The purpose of this study was to test the hypothesis that offering faba beans as a supplement more than once a day to sheep receiving a combination of oaten chaff and lucerne chaff as a basal diet will increase microbial protein supply to the intestines. The experiment was conducted in a Latin square design (4 x 4) using four mature merino sheep. The treatments were: T0 = basal diet ad libitum + nil supplements, T1 = T0 + faba beans (FB) fed once daily, T2 = T0 + FB fed twice daily, T3 = T0 + FB fed 8 times daily. The basal diet was given once per day at 09:00 in the morning while FB were given at the rate of approximately 0.5% of live body weight and delivered according to the treatment protocol. Urinary excretion of purine derivative (PD) was used to estimate microbial protein supply. The results indicated that even though treatment statistically had no effects on total urine output, PD excretion in the urine, PD absorbed, estimated microbial N supply, and the efficiency of rumen microbial protein synthesis, provision of supplement to sheep numerically improved microbial N supply by 92% compared to that of control group. However, there were no differences within the supplemented group. Therefore, it is concluded that feeding faba beans more than once a day was unnecessary.

Abstract

The study was conducted in the Tiromanda village, South Makale sub district, Tana Toraja district. The aim of the study was to measure the effect of providing agricultural waste based feeding to buffalo fattening. Fifteen male buffaloes, aged between 3 - 5 years with body weight ranging between 200 and 250 kg, were randomly assigned to one of three experimental diets, namely (A) 12 kg fermented rice straw + 2.5 kg concentrates; (B) 10 kg fermented rice straw + 5 kg concentrate and (C)control diet (ration typically used by the farmer) according to completely randomised design. Formulation of feed was based on agrricultural waste locally available, i.e. rice straw and concentrates. Determination of body weight was carried out every month for four months. The results showed that the average daily body weight gain (ADG) of buffaloes in the treatment B was the highest compared to that of the treatment A and C, namely 0.8 kg/head/day; 0.6 kg/head /day and 0.3 kg/head/day, respectively. Feed conversion ratio for each treatment was 31.6 (A), 14.87 (B), and 41.3(C). In conclusion, provision of feed based on agricultural waste such as rice straw plus concentrates increased body weight gain in fattening buffaloes.

Abstract

Abstract.  Cereals and legumes used as animal feed containing phytic acid which cannot be absorbed by the digestive tract of monogastric animals because phytic acid (C6H18O24P6) is an antinutrient that binds approximately 80% P in feed, also binds to proteins, vitamins and minerals (Mg++, Fe++, Zn++, Mn++, Ca++). Then, one option to overcome this problem is the application of phytase enzymes from various sources, including those produced by bacteria. Phytase enzymes can hydrolyse phytic acid in the feed. This study was aimed to determine the growth phase of Burkholderia sp. HF.7 and optimisation of production of phytase activity from variations of Phytate Production Media (PPM) media. This research used as a descriptive approach. The study design used a completely randomised design (CRD) with a factorial pattern consisting of 2 factors, each variation in phytate sources: calcium (Ca) phytate, rice bran, corn bran, and soybeans. Nitrogen source: (NH4) 2SO4, yeast extract, and peptone. Burkholderia sp. HF.7 Growth phase as a standard for phytase production is the 62-hour stationary phase with an OD value of 2.060 log/cell. The optimum phytase production in the variation of PPM media is soybean-peptone with a protein content value of 46.5 mg/mL and an activity value of 8.20 U/mL under conditions of pH 7 with incubation of 37oC for 62 hours. So, phytase activity produced by PPM of cereal crops has a higher current value compared to PPM Ca-phytate media with low activity value.Keywords: Burkholderia, Phytate, Phytase, enzymes.
