Abstract

Sixteen Ettawah cross bred goats were used to study the effect of waru leaf (Hibiscus tiliaceus)sapponin combined with soybean meal protein supplementation on some parameters of proteinmetabolism. Goats had body weight average of 16 kg and aged at 7 months. The experimental dietswere: T0 = total mixed ration (0.9% saponin of hibiscus leaf, 8% CP, 62% TDN), T1 = T0 + 3% soybeanmeal protein, T2 = T0 + 6% soybean meal protein, and T3 = T0 + 9% soybean meal protein. Thetreatments were allocated in a completely randomized design. The parameters observed in this studywere dry matter (DM) and crude protein (CP) intakes, DM and CP digestibilities, ruminal amonia andVFAs concentrations, blood urea level, nitrogen retention, digestible organic matter in rumen (DOMR),urinary allantoin, and estimated microbial nitrogen (N) synthesis. DM intake, DOMR, urinary allantoinand estimated microbial N synthesis were not affected significantly (P>0.05) by treatments. CP intake,DM and CP digestibilities, ruminal amonia and VFAs concentrations, blood urea level and nitrogenretention increased (P<0.05) with increasing levels of soybean meal protein. Balancing energy levelshould be considered for the dietary protein supplementation in Hibiscus tiliaceus leaf contained diet of goat.

Abstract

The study was aimed to explore the role of cooperativism in dairy cattle farming in Getasan village,Semarang Regency, Central Java Province. Spearman Rank Correlation test was used to determine therelationship between cooperativism and the performance of dairy cattle farming. Based on the results ofthe Spearman Rank correlation test, feeds and feeding practices were significantly correlated withsharing of knowledge and information and sharing of resources. However, no significant relationshipwas found between participation in decision making and feeds and feeding practices. Meanwhile, therewere significant relationships amog sharing of knowledge and information, sharing of resources, andparticipation in decision making and milk production in Getasan Village. The dairy health asperformance indicator of dairy cattle farming, sharing of knowledge and information was the onlysignificant factor. Sharing of resources and participation in decision making had no significantrelationship with dairy health. As regards marketing, the test showed that sharing of knowledge andinformation, sharing of resources, and participation in decision making were significantly relatedfactors. This study indicated that cooperativism may provide opportunities for farmers to accessservices, information and resources that will allow them to improve their capacities in these areas. Thisstudy also proposed some recommendations that the cooperatives should promote activities encouraginggreater cooperation and mutual understanding among the members. Skills trainings and education forempowerment should be conducted to encourage participation in decision making.

Abstract

This research was aimed at studying the in vitro ruminal biohydrogenation (BH) of C18 fatty acids (FA) in mixtures of Indigofera zollingeriana and Brachiaria decumbens. Four combinations of experimental rations of I. zollingeriana : B. decumbens were tested i.e., IZ 1 (45%:45%), IZ 2 (60%:30%), IZ 3 (75%:15%), and IZ 4 (90%:0%). The remaining 10% in in each ration was rice bran. The experimental design was based on a completely randomized design with five replicates. Results revealed that there was a statistically significant difference (P<0.01) in the composition of C18 unsaturated FA (UFA) and saturated FA (SFA) for each in vitro incubation period of 1, 2, 4, 8 and 24 h. The highest accumulation of C18 UFA at 24 h was observed in the incubation of IZ 4 (19.87%). The BH of C18:3, C18:2, and C18:1 showed no differences (P>0.05). Composition of C18:0 after incubation showed a significant difference (P<0.01) with the lowest composition was observed in IZ 2 (22%). In conclusion, combination of I. zollingeriana and B. decumbens at different ratio has minor inhibition effect on BH of C18 UFA.

Abstract

The objective of this research was to identify growth hormone (GH) genes genotype in selectedAceh cattle at Indrapuri’s Breeding and Forage Centre (IBFC) of Aceh Cattle. Fourty one cattleconsisting of 21 male and 20 female cattle were used in this study. The genomic DNA was extractedfrom blood using Sambrook et al. (1989) methods. Polymerase Chain Reaction - Restriction FragmentLength Polymorphism (PCR-RFLP) and mehod of sequencing was used to detect MspI site on GH gene.Based on sequencing results, it can be concluded that all cattle were monomorphism. The frequency ofTT genotype were 1.00 and same as T allele frequency. The transition of C (cytosine) into T (thymine)on 1548 bp caused the lost of restriction site.

Abstract

The study was conducted to investigate the in vitro antibacterial activity and antioxidant-enhancing effect of Bacillus strains isolated from the rumen content of dairy cows. The antibacterial activity of Bacillus strains was assessed against Escherichia colibased on the agar-well diffusion method. To assess the antioxidant-enhancing effect, the Bacillusstrains was mixed (prepared as multi-strains) and used to ferment herbal medicine waste (HMW). The effect was compared with that of commercial probiotic Bacillus subtilis and non fermented HWM. Results showed that each Bacillus strain was able to inhibit the growth of E. coli. Fermentation with mixed Bacillus strains tended (P=0.07) to enhance the 2,2-diphenylpicrylhydrazyl (DPPH) radicals scavenging activity and total phenolics content of HMW. In contrast, fermentation with commercial Bacillus subtilis tended (P=0.07) to decrease DPPH radical scavenging activity and total phenol of HMW. Fermentation with both Bacillus preparations increased (P<0.05) the contents of crude protein and ash in HMW, while crude fat increased  (P<0.05) in HMW fermented with Bacillus subtilis. Fermentation either with Bacillus subtilis or mixed Bacillus strains increased (P<0.05) the fiber content of HMW. In conclusion, Bacillus strains isolated from the rumen content of dairy cows showed antibacterial activity and antioxidant-enhancing effect, therefore, they are potential as feed additive to substitute synthetic antibiotics and antioxidants for broilers raised under tropical conditions.

Abstract

Ten Hereford bulls housed indoors in individual tie stalls were used to explore the relationshipsatmospheric ammonia exposure and microclimate on beef cattle hematochemical, and to know effectand to prediction equations the atmospheric ammonia exposure and microclimate with varioushematochemical parameters. This study was conducted in Animal Station, Department of AgriculturalBiotechnology, Seoul National University (SNU), Seoul, South Korea, for 40 days during summer.Results of this study indicated that there were negative correlation between ammonia with temperatureand positive correlation between ammonia with humidity. There were significantly negative effect ofammonia on hematochemical, except neutrophyls and ratio of neutrophyls to lymphocytes.Simultaneous effect between ammonia, temperature and humidity, mainly effected on glucose,hexokinase, lymphocytes, neutrophyls, N:L Ratio, and lactate. Simultaneous effect between ammonia,temperature and humidity proved to be a good indicator for predicting the profile of glucose,hexokinase, lymphocytes, neutrophyls, N:L Ratio in the blood.

Abstract

The study was constructed to observe the effect of rice hull as a fiber sources in the dried hotelfood waste based-diet on fat and cholesterol level of pork. Twenty four heads of two months old ofLandrace x Yorkshire cross barrows were randomly divided into four treatment groups, i.e. without ricehull (R0), 10% rice hull (R1), 20% rice hull (R2), and 30% rice hull (R3). They placed in individualconcrete pen with 1.9 m in length and 0.5 m in width. Feed and water were given as ad libitum.Observation was done for 10 weeks prior to slaughter. Completely Randomized Design was used in thisstudy. Data obtained was analyzev by anova and mean comparison of Duncan's new Multiple RangeTest. Fat content of R0, R1, R2, dan R3 pork were 14.09±0.31, 13.30±0.44, 12.9±20.30 and11.95±0.56%, respectively. Fat content of pork of R0 was higher (P<0.05) than that of others groups.Cholesterol content of pork of R0, R1, R2 and R3 were 256.47±30.23, 252.34±26.56, 217.63±21.93 and199.21±25.94 mg/100 g, respectively. Cholesterol content of pork of R3 were lower (P<0.05) than thoseof R0. It is concluded that the use of rice hull up to 30% in the dried hotel food waste based-diet candecreases fat and cholesterol levels of pork.
