Abstract

ABSTRACT. The production of Casein hydrolysate with an extracellular proteinase from Lactobacillus helveticus CP790, was fractionated by two-step reverse phase heigh performance liquid chromatography. Only 1 fraction showed antihypertensive activity as measured by systolic blood pressure in spontaneously hypertensive rats after oral adsministration. Ten peptides in the fraction were further purified and identified by analisys of amino acid sequences. Each identified peptide was chemically synthesized, and the ant.ihypertensive activity of each peptide was evaluated in spontaneously hypertensive rats. The synthetic peptide with a sequence of Lys-Val-Leu-Pro-Val-Pro-Gln, found in -casein, indicated strong antihypertensive activity from 2 to 10 h after oral adsministration of 2 mg of peptide/kg of BW, and the effect was maximal at 6 h after oral adsministration. Moreover, the antihypertensive effect of the peptide was dependent on the dosage of peptide from 0.5 to 2 mg o peptide/kg of BW.

Abstract

ABSTRACT.Sheep are small ruminant that have been adapted and close to human. They are easily raised and contribute to family enterprise income. They are usally raised in public land, unplanted paddy field, and under palm plantation. Research on raising sheep under paim plantation was conducted from 9 October 1996 to 21 january 1997. The research was conducted at PT. Pasriwisata, Damar Siput, Rantau Slamat, Eastern Aceh. Thirty sheep were used in this experiment. They were crossbreed of Hairsheep St. Croix males with local female (F1 x F1). Therefore, the sheep had 50 percent of local sheep blood and 50 percent of Hairsheep St. Croix blood. They were borrowed from Sei Putih Liverstock research center, Galang, North Sumatra. They were divided into three group of 6, 10 and 14 heads respectively. Each group was grazing on 1 ha pasture under palm plantation. All sheep got the same treatment and no supplement was fed the animal. They were grazing for 4 hours a day. The result showed that there was no significant differences. ( P 0.05 ) on daily body weight gain among the threatments. Mean daily body weight gain or each group was 30 g, 35 g and 36,22 g for group 6, 10 and 14 heads respectively. This finding was relatively the same as reported by ditjennak ( 1 ) and ginting ( 2 ) where daily body weight gain was about 30 to 40 g for sheep those were extensively grazing under rubber plantation without supplement and were grazing for 6 to 8 hours day. Body weight gain of sheep is not only determined by the excessive availability of forage, but also by the number of sheep that are grazing at the same time on the same pasture. Number of sheep are grazing on the pasture competitively encourages sheep to graze the pasture more. Tilman et al. ( 3 ) stated that animal that eats more give higher body weight gain than animal eats less.

Abstract

ABSTRACT.The effect of sex and old to carcass and offal of swamp Bufallo at Rumah Potong Hewan Banda Aceh, have been done in Banda Aceh as long as 10 days. The material that was used were swamp bufalloes from Banda Aceh regency, as much as 36 bufalloes, that was sparated 18 females and 19 males. The aim of this study was to know the partial and interaction effect of sex and old to carcass percentage and offal of swamp bufalloes. The method used of this study was direct observation at Rumah Potong Hewan. The variable that was knowed were; the heavy of: weight, carcass, head, hide, heart, feet, liver, lungs, spleen, full digestive tract, and the carcass percentage. The data collected was Analyzed by completely Randomized Design (CRD), wich 3x2 factorial pattern and six times replication. As a main factor was old, that was sparated by 3 4 years, 4 5 years, and 5 years. The data was tested by Duncans test. The result of this study showed that was not any interaction effect of old and sex to carcass percentage and offal. Also, that not any effect of sex to carcass percentage, but effect of sex was significance different to offal. The other hand, not any effect of old to carcass percentage and offal.

Abstract

ABSTRACT.The ratio of D-and L-lactic acid produced in media by 39 strains of the L. acidophilus group lactic acid bacteria (A1-A4,B1, and B2 subgroups) was analyzed by high performance liquid chromatography (HPLC). L. acidophilus (A1) and L. jhonsonii (B2) produced the lowest ( 5 strains average : 41.9%) contents of D-lactic acid in MRS broth, respectively. Generally, the most dominant lactic acid (more than 50%) produced by each strain in MRS broth was a D-type isomer, except for the A1 subgroup. In L. gasseri DSM 20243T (B1), increases in the sugar content in MRS broth induced both a high production of total lactic acids and a high ratio of D-lactic acid. In skim milk, D-lactic acid decreased by 20 30 % in 5 strain types of the L. acidophilus group except L. amylovorus JCM 1126 T (A3). By sequentially changing the medium, the content of D-lactic acid in the final MRS broth reverted to almost the same level of that in the initial MRS broth. These results indicated that the ratio of D-lactic acid produced by L. acidophilus group bacteria may be controlled by improving fermentative condition

Abstract

ABSTRACT.Studies have been made on the isolated urinary bladder of the toad, Bufo marinus, in an attempt to investigate the effect of vasopressin on the permeability of water from mucosal surface to serosal surface of the toad bladder. The method adapted was that described by Bentley ( 1 ). The bilobed bladder of the toad is devided into two separate sacs. Each of the sacs is filled with a dilute Ringers solution and then immersed in aerated isotonic Ringers solution. The rate of water loss along the imposed osmotic gradient is estimated by weighing the sacs in air at 30 minute intervals and nothing the weight loss in that time period. In most studies one bladder sac serves as a control for the contra lateral experimental obtained from the same animal. Osmotic flow of water is negligible in both sacs during the initial control periods. However, the addition of vasopressin to the solution bathing the serosal surface of the membrane result in a market increase in net water movement. The effect is readily reversed by rinsing the bladder and adding hormone free Ringgers solution to the serosal surface. Characteristically no response is elicited by addition of hormone to the mucosal bathing solution.

Abstract

ABSTRACT. A study on how to improve the efficiency and the effectivity of the Inseminators work in beef cattle SPAKU area has been done. The study was designed as a field experimentation which used 40 prolonged anestrus postpartum cows. Sample cows were divided into two groups which consisted of control group (20 heads) and treatment group (20 heads). The treatmet group were treated with CIDR in order to allow oestrous synchronization at the end of the treatment. The result of the study showed that synchronization protocol allows the inseminator to work according to a preplanned schedule and to inseminate a number of oestrous cows in one working day. Statistical analisys indicated that all cows which were treated with CIDR became pregnant compared with those of control group. It can be said that oestrous synchronization with CIDR had higly significantly increased pregnancy percentage in treatment group (P0,01) compared with those of control group.

Abstract

ABSTRACT.Experiment were conducted to evaluate fermentation characteristics (pH, NH3, VFA), On degration in sacco degration neutral detergent fiber (NDF), acid detergent fiber (ADF) and neutral detergent insoluble nitrogen (NDIN) of feed particle in the rumen. Two fistulated Friesien Holstein grade of each feeding used in this research. The ration in given similar with the sample to measured the degration in the rumen are corn stover (CST) and sugar cane top (SCT). Disappearance of the NDF, ADF, and NDIN in the rumen was calculated based on the incubation time and using an exponential negative modwl Y= a + b (1-e-ct) from Orskov and Mc Donald, (1979). Values of a,b and c fraction were used to calculate theoretical degradation DT=a+ ((b.c)/(c+Kp)) with the assumption of flow of particle (Kp) is about 5 %/hour. The results on fermentation characteristics of feeding corn stover give ph about 6.54 0.16; N-NH3 about 7.36 3.10 mg/100 ml and VFA about 64.84 10.82 mmol/1, whilst for feeding sugar can to give ph about 6.54 0.14; NH3 about 2.62 0.85 mg/100 ml and VFA about 44.13 6.7 mmol/1. The microbe activity of the degration (DT) borh fed were not significantly different for NDF and ADF but for NDIN showed significantly different (P0.05) among feeds. This results show that there utilization of single feeds corn stover and sugar can top are not optimal for microbe activity, however the values degradation of fiber fraction were above 30%.
