Abstract

The experiment was conducted to evaluate chemical characteristics and biological value of protein concentrate extracted from palm kernel meal (PKM) using combination of physical and chemical extraction. The best method of extraction in term of total amino acid (TAA), essential amino acid (EAA), essential amino acid index (EAAI), and protein recovery then was used for protein retention evaluation using 20 heads of male quails age 30 days. The animals were randomly assigned to one of three dietary treatments, while the remaining quails were used to measure endogenous protein. The treatments were; R1=diet containing 9% crude protein from the best protein concentrate from PKM, R2=diet containing 9% crude protein from PKM and R3=diet containing 9% crude protein from soybean meal). The results showed that protein of PKM had isoelectric pH in a range of 4.3-4.4. Protein concentrate of PKM produced by grinding using 0.05 N acetic acid followed by soaking 1 N technical-NaOH had the highest protein quality compared with those of the other treatments. TAA, EAA, EAAI amount of precipitate and protein recovery of the protein concentrate were 33.38%, 16.76%, 62.41%, 12.18% and 50.38%, respectively. Protein retention of quails fed R1 was not different compared to that of R3 (69,82 vs 70,57%), while quails received R2 had the lowest protein retention value (61,19%). It is concluded that combination methods of physical and chemical extraction using 0.05 N acetic acid followed by soaking with 1 N technical NaOH (E3) was the best method in producing high quality of protein concentrate, and the product had similar protein retention value as that of soybean meal. Key words: chemical characteristics, biological value, protein concentrate, palm kernel meal, extraction

Abstract

The experiment was conducted to determine the optimum synchronization ratio of N-protein and fermented organic matter (OM) in the rumen for the purpose of ration formulation for ruminant animals, in order to improve efficiency of rumen microbial N synthesis and feed efficiency. Nylon bag technique was adopted to determine ruminal characteristic of protein and OM degradation of feedstuffs (forage and concentrate diet) for which the synchronized index of N-protein and fermented OM in the rumen might be determined. By randomized block design, twelve local cattle were arranged to four groups. Each group was fed three types of diet that was different in synchronization ratio of supplying N-protein and fermented OM in the rumen, namely 20 g N/kg OM (R20); 25 g N /kg OM (R25); and 30 g N /kg MO (R30). The diets had iso-energy and iso-protein contents and had the same synchronization index. The results showed that the type of diet had no effect (P>0.05) on intake and digestibility of nutrients, N retention, average daily gain (ADG), and feed efficiency. But R20 had better parameter values than those of R25 and R30. It might be concluded that the diet having a synchronization ratio of 20 g N/kg fermented OM in the rumen will generate more efficient protein synthesis of rumen microbes and feed efficiency. Key words: synchronization index, microbial protein synthesis, ruminal characteristic

Abstract

An experiment was conducted to determine the effect of feeding tapioca by-products fermented by Neurospora crassa on layer performances and egg quality. Two hundred layers were randomly allocated into 20 pens. This experiment was arranged in a completely randomized design with four dietary treatments: 0%, 10%, 20% and 30% tapioca by product fermented by N. crassa in the diets and five replications. Variable measured were feed comsumption, egg production, feed conversion, egg cholesterol and egg yolk colour. Results of the experiment indicated that feed comsumption, egg production, feed conversion, egg cholesterol and egg yolk colour were affected (P < 0.05) by using fermented tapioca by-product in the diets of layers. Results of Duncan multiple range test indicated that feed consumption, egg production, and egg yolk colour in D treatment (used 30% tapioca by-products fermented) were the highest compared to those other treatments, but the lowest on feed conversion and egg cholesterol. The conclusion of the experiment that tapioca by-products fermented by N. crassa can be used up to 30% in the diet of layer. Key words: tapioca by product fermented, Neurospora crassa ,layer performances, egg

Abstract

The objectives of this research were: 1) to find out whether acid rain has taken place in Bogor Regency area and its effect on the lead (Pb) content in soil and roughage in the region, 2) to predict the correlation of Pb content in rain water and soil, and the content of Pb in roughage in the Bogor regency area, 3) to study the impact of acid and Pb content in the ration to sheep daily gain and measure Pb content in liver, kidney and meat. The results showed that in Bogor regency area the acid rain occurred during the dry season but not in the wet season. The Pb content in the rainwater and soil were not affected by acid rain. There was no correlation of Pb content between soil and roughage. Acid containing ration decreased daily gain, but not for the ration of high Pb-content. Acid containing ration increased Pb content in the kidney but not in the liver and meat. However, high Pb content in the ration increased the Pb content in the liver and kidney but not in the meat. Key words: acid rain, Pb, Bogor, local sheep

Abstract

Many theories highlighted the critical importance of knowledge creation on the long-term success of the organization. However, the scarcity of empirical work on knowledge creation model has limited our understanding of the overall organizational process involved. To overcome this, we attempt a comprehensive analyze of knowledge creation model within the organization, exploring the relationship between innovation, knowledge creation model, problem-solving capability, absorptive capacity, knowledge acquisition and assets. Data of this case study were taken from three dairy cooperations in Java. Analysis was conducted using Structural Equation Modeling (SEM) with Lisrel 8.72. The results revealed that several contributing factors (problem-solving capability, absorptive capacity, knowledge acquisition and assets) had significant effect on innovation. On the other hand, knowledge creation model had no significant effect on innovation in the context of the dairy cooperation in Indonesia. The implication for managers is that by focusing on externalization process in knowledge creation model within the organization. In the pattern of innovations, product innovation is the most important. Key words: innovation, knowledge creation, problem-solving capability, absorptive capacity, dairy cooperation

Abstract

Forage conservation has long been a part of the agricultural scene in some countries in the world. Ensilage is a preservation method for moist forages that is based on natural lactic acid fermentation under anaerobic conditions. There are six phases which occur during ensilage, storage and feed-out of the fermented forages. The technology of silage making is not popular in Indonesia, although ensilage may successfully occurs in tropical area including Indonesia. The reason may be due to limited information available regarding ensilage for the farmers. This review covered silage fermentation process and probiotics effect of feeding silage to the ruminants. The role of lactic acid bacteria is very important both from the preservation and antimicrobial points of view. Key words: lactic acid bacteria, fermentation, silage, probiotics

Abstract

The optimal storage temperature for preserve boar semen is 17-18°C. The temperature fluctuations can decrease sperm viability. The aim of this study was to obtain a boar semen extender for Artificial Insemination (AI) at a certain distance area. The observation was based on the sperm viability in modified Beltsville Thawing Solution (BTS) extender in different storage, and the effect of storage system i.e.: room temperature (22°C) and styrofoam box (18°C) were conducted for this purpose. The research used a completely randomized design (CRD) with two factorial i.e.: BTS and M-BTS extender (F1), room temperature and styrofoam box (F2). Semen from three years old Yorkshire boars (n = 3) were collected twice a week by glove hand method. Semen characteristics and their quality were evaluated macro and microscopically. These semen were added with BTS and M-BTS extender up to fourfold volume (ratio 1 : 3). This is based on the assumption of AI dose of 2 - 3 x 109cells/80ml and the sperm motility and viability were evaluated every six hours for 24 hours observation. The results showed that fresh semen characteristics were good, with the percentage of sperm motility 65.56±2.55% and sperm viability of 87.70±2.87%. The best extender found in this experiment of 24 hours observation was BTS extender with sperm motility 53.33±3.33% in styrofoam box. In conclusion, BTS extender can maintain the quality of spermatozoa stored in styrofoam box for about 24 hours with sperm motility 40%-50%, and the styrofoam box can be used as an alternative container for insemination program in the field. Key words: sperm viability, semen extender, storage, boar sperm

Abstract

The objective of this research was to determine the effects of dietary cation-anion difference (DCAD) on acidity of ration, blood, vaginal mucous, and urine, number of fetus, number of offspring, and offspring sex ratio. The treatments were rations with DCAD -28, -18, 0, +14, and +32 meq which were offered to 15 ewes. This research used randomized complete block design. There were three groups, (I) ewes previously had twin female offsprings; (II) ewes previously had twin male offsprings; and (III) ewes previously had twin male and female offsprings. Results of this study showed that there were no differences observed for blood's pH, vaginal liquid's pH, offspring number, and offspring sex ratio. Increasing DCAD affected ration's pH, urine's pH, and number of fetus for each ewe. Blood's acidity was not affected by DCAD, but DCAD -28 meq reduced acid of blood, metabolic acidosis, and urine; the number of fetus and offspring. DCAD -28 meq might be anions excessive in the ration. DCAD 0 meq was relatively the best of ration because gave the normality of blood, metabolic, and urine, also relatively the highest of fetus and offspring. The offspring sex ratio related to vaginal mucose pH when artificial insemination was applied (r= 0.75) and ration's pH (r=0.47). Ewes previously had twin female lambs gave the number of fetus and offspring sex ratio were 2.00+0.71 and 0%, respectively. Ewes previously had twin male lambs gave the number of fetus and offspring sex ratio were 2.80+1.30 and 15.00+8.50%, respectively. Ewes previously had twin male and female lambs gave the number of fetus and offspring sex ratio were 1.60+1.14 and 61.75+31.50%, respectively.Key words: DCAD, pH, offspring sex ratio, lamb, ewe

Abstract

Dendeng is a typical Indonesian jerked meat commonly made from sliced or ground beef with 2 mm thickness. This research was conducted to study the effect of kind of meat and leaching method on pH, toughness, protein, fat content and peroxide value (PV) of ground jerked meat. The experiment was set up in a completely randomized factorial design with three replications. The first factor was three levels of leaching methods (no washing, washed in 1.5 x 1.5 x1.5 cm size and washed minced meat). The second factor was kind of meat namely horse meat, lamb and beef. The results indicated that neither interaction effect between leaching and kind of meat nor effect of leaching were significant on all characteristics observed. Kind of meat influenced significantly on the pH, toughness, fat content and PV of dendeng (P < 0.01). Key words: dendeng, physical-chemical characteristics, leaching

Abstract

The aim of this research was to measure the relationship of the pH value to the somatic cell count as a parameter of sub clinical mastitis detection. Two hundreds quarter milk samples were used in this research and the test (the pH value, IPB-1 mastitis test and Breed method) was done in parallel way. The results showed that 152 samples from 200 samples (76%) tested with Breed method came from the herds which suffered from sub-clinical mastitis and with IPB-1 test showed that 145 (72.5%) of the samples had positive reaction. Using pH meter, it showed that 44 samples (22 %) had pH > 6.75, presumed suffered from sub-clinical mastitis and 2 samples (1%) showed pH < 6.30 (6.25 and 6.28). At the same time, these two samples showed a negative reaction with IPB-1 test and had somatic cell count of 360,000/ml and 280,000/ml, each. It also showed that there was a close relationship between pH value and IPB-1 test. The conclusion of this research was that the measurement of pH value was not a sensitive method for detecting sub-clinical mastitis. Key words: sub-clinical mastitis, pH, somatic cell count, IPB-1 mastitis test
