Abstract

The present study was done to observe effect of agroclimate on milk production and prevalence of sub-clinical mastitis of local Holstein-Friesian dairy cattle in Indonesian small holder dairy farms. The research side were located in Region of <1000 masl and ≥1000 m above sea level (asl) in west Java. Data were obtained from 133 small holder dairy farms included 336 dairy cows in normal lactation period. Parameters observed were agro-climate condition, feed consumption, milk production and milk quality, and sub-clinical mastitis prevalence. Result sowed that THI at <1000 m asl had a range of 76.1-76.7 leads to mild heat stress, while THI at ≥1000 m asl had a range of 66.2 - 66.8 which makes comfort environment to the dairy cow. Differences in feed consumption (P<0.01), milk production and quality (P<0.05) were found among two altitude study location. Milk production at ≥1000 m asl was 2.3 kg higher than at <1000 m asl. The udder health status was also different, a 51% of total sample at <1000 masl was detected sub-clinical mastitis (SCM) as high criteria, while 42% samples that were collected at ≥1000 m asl detected sub-clinical mastitis as middle criteria. In conclusion, agro-climate condition (THI) affect animal’s comfort, milk production and sub-clinical mastitis prevalence.

Abstract

A study was conducted to identify the variations of the myostatin and also to evaluate the existence of genetic marker for “double muscling” (11-bp deletion in the third exon of the myostatin gene) in the first generation of Belgian Blue cattle in Indonesia using the Single Strand Conformation Polymorphism (SSCP) and the sequencing analysis. A total of 8 DNA samples belonged to Karya Anugerah Rumpin (KAR) Farm were used in the Single Strand Conformation Polymorphism (SSCP) and the sequencing analysis. There were 3 allele types of myostatin gene based on the SSCP analysis. The Belgian Blue sire has type A allele. The Simmental, Wagyu, SO x BX, Charolais, and the PO cattle have the type B allele, while the Belgian Blue x FH and the Belgian Blue x SO have the type C allele (heterozygous). There are 11-bp deletion in the third exon myostatin gene for the Belgian Blue sire based on the sequencing analysis. The myostatin gene in the Belgian Blue F1 generation individual was heterozygous. This study provides scientific evidence that the 11-bp deletion in the third exon of myostatin gene in the Belgian Blue sire was inherited to its F1 generation (male and female).

Abstract

Lignin is limiting factor for cellulose and hemicellulose degradation in rumen. Isolation andselection bacteria from buffalo and horse gastrointestinal tract and elephant dung could be foundbacteria that have superiority to degrade lignin, xylan, and cellulose. Those animals were chosenbecause they were herbivores that consume low quality crude fiber as their main energy sources.Lignocellulose degrading bacteria were isolated by Hungate selective media, by using lignin (tannicacid), xylan, and cellulose as selective substrates. The morphological identification used an enrichmentmedia by measuring color, colony size, diffusion zone, clear zone, and biochemical identification usingproduction of ligninase, xylanase, and cellulase enzymes. The best lignocellulose degrading bacteriathen was determined by the morphological and biochemical character. This study showed thatlignocellulose degrading bacteria could be found in gastrointestinal tract of buffalo and horse, andelephant dung. Highest number colony was found in samples from buffalo's colon (376), followed byhorse's cecum (203), elephant’s dung (46), buffalo’s cecum (23), buffalo's rumen (9) and horse’s colon(7). The highest isolates activity of lignolytic, xylanolytic, and cellulolytic were reached by buffalo’scecum (7.64), horse's cecum (6.27), and buffalo’s colon (2.48). Meanwhile the highest enzymesproductivities were: buffalo’s cecum (0.0400 µmol), horse’s cecum (1.3912 µmol) and buffalo’s colon(0.1971 µmol). Based on morphologycal character and biochemical test, it could be concluded thatlignolytic from buffalo’s cecum, xylanolytic from horse’s cecum, and cellulolytic from buffalo’s colonwere the superior isolates and they were 99% analyzed as Enterococcus casseliflavus/gallinarumspecies.

Abstract

The aims of this study were to obtain information on the mechanism of molting and the prolactinhormone levels affecting egg production. The study utilized AP (crossbred of Alabio ♂ with Peking ♀)and PA (crossbred of Peking ♂ and Alabio ♀ ducks) with a total of 180 birds. The observed variableswere the duration of cessation of egg production before and after molting, the prolactin hormone level inthe period of molting, the egg production period before and after molting. The data was analyzed usingANOVA, regression and correlation. The results showed that AP crossbred had fewer molting (23.33%)compared to PA (50.00%). The mechanism of molting is always preceded by cessation of eggproduction, molting and relaying. The prolactin hormone concentrations of AP and PA in the periodbefore and after molting were significantly higher than in the period of molting. At the egg productionperiod before molting, the prolactin hormone concentration of AP ducks was higher than the PA ducks.So that the egg production of AP before molting (0-16 weeks) was higher than the PA. The eggproduction of AP was higher than PA, 256.66±6.00 vs 232.22±6.64 eggs for 48 weeks. So it can beconcluded that the prolactin hormone affects the molting and egg production.

Abstract

The objective of this study was to develop models for determination the superiority of Holstein bulls as a producer of frozen semen and inheritance of the genetic traits of milk production. The ability of the bull to produce frozen semen per years was analyzed descriptively. Reproductive efficiency of frozen semen in artificial insemination was calculated by service per conception (S/C). Estimation sire breeding value for milk production was calculated by contemporary comparison (CC) method. Model of superiority bulls was analyzed by Structural Equation Model with Partial Least Square method (SEM-PLS). Total average production of frozen semen was 23,109±14,970 doses/year. The average S/C was 2.83. The CC value ranged from -1,865.7 until +1,636.3. Potency of milk production resulted from lactation cow offspring per bulls ranged from 951,749.2 to 52,347,822.9 liters per year. The economic value of bulls based on the potency milk production of offspring ranges from IDR 4,758,745,999 to IDR 261,739,114,505. The superiority of bulls was affected significantly (P<0.05) by frozen semen production, reproductive efficiency and average milk production of daughter cows (DC) as much as 0.59, -0.53 and 0.33, respectively. In conclusion, the superiority of bull can be explained about 78.3% by the production of frozen semen production, reproductive efficiency and milk production of offspring.

Abstract

The objective of this experiment was to obtain an optimum combination between field grass,concentrate and Nutrient Rich Supplement (NRS) based on in vitro study using Hohenheim gas test. Theexperimental diets were: R1 (control diet = 70% field grass + 30% concentrate), R2 (70% field grass +25% concentrate + 5% NRS), R3 (70% field grass + 20% concentrate + 10% NRS) and R4 (70% fieldgrass + 15% concentrate + 15% NRS). A randomized block design with four treatments and fourreplications was carried out. Buffalo rumen fluid was taken in different time and was used as block orreplication. Data were analyzed by Analysis of Variance (ANOVA). Significant differences amongtreatments were determined by contrast orthogonal. The results showed that total gas production andtotal VFA concentration were highest (P<0.05) in R4 among the treatments. Addition of 15% NRS incomplete ration (R4) increased NH3 concentration 10.34%. Addition of 10% NRS and 15% NRS incomplete ration (R3 and R4) improved the microbial biomass product compared to control and 5% NRSin complete ration (R1 and R2). Dry matter (DM) and organic matter (OM) degradability weresignificantly higher (P<0.01) in 10% NRS and 5% NRS in complete ration (R3 and R2) compared tocontrol and 15% NRS in complete ration (R1 and R4). It was concluded that combination between 70%field grass, 20% concentrate and 10% NRS in complete ration (R3) was more optimal for improving gasproduction, total VFA, NH3 concentration, microbial biomass product, dry matter degradability andorganic matter degradability, compared to control ration.

Abstract

The objectives of the present study were to compare and determine the best post-thawed characteristics of balinese bull sperm cryopreserved in three different extenders; animal based (Tris-clarified egg yolk (Tris-cEY)), and non-animal based extenders (Bioxcell® (lecithin based) and Optixcell® (liposome based)) in combination with three different equilibration times (30 minutes, 2 hours, 4hours). Thirty six ejaculates were collected from six Balinese bulls and frozen in three extenders (Tris-cEY, Bioxcell® and Optixcell®) after equilibration in three different times (30 minutes, 2hours and 4hours). Computer-assisted sperm analysis (CASA), hypo-osmotic swelling test (HOST) and eosin nigrosin staining were used in the post-thawed semen analysis. There was a significant interaction between equilibration time and extender type for sperm motility, viability and membrane integrity. Thirty minutes equilibration time had the lowest values (P<0.05) for all the evaluated parameters independent of extender type. Overall, semen extended in Tris-cEY, Bioxcell® and Optixcell® were similarly better when equilibrated at 4 hours (P>0.05). Moreover, post-thawed semen which were extended in Optixcell® for 2 hours equilibration showed a better motility compared with the other extenders (P<0.05). In conclusion, two hours equilibration of semen with Optixcell® is sufficient for semen freezing. Four hours equilibration has the best sperm survival, independent of the extender type.

Abstract

The objective of the research was to identify the effect of the concentration of hydrochloric acid (HCl) on yield and the characteristics of gelatin from buffalo hide. A completely randomized design was used with various concentrations of HCl treatment 0.3M, 0.6M, 0.9 M, 1.2 M and 1.5M, and four times replication, followed by least significant difference test. The HCl concentration gave significantly effect (P<0.05) on yield, viscosity, pH, gel strength and redness of gelatin. The highest yield (29.17%) was obtained at a concentration of HCl 0.9M. The highest gel strength and viscosity at concentration of 1.2M, were 293.41g bloom and 22.17 cp, respectively. The pH of the gelatin were 5.08 to 5.52. The lightness level (L*) was 69.92-70.97, whereas the redness ranged (a*)  from 0.55 to 1.54 and the yellowness ranged (b*) from 17.54 to 19.59. The moisture, protein and ash concentrations of gelatin were 7.05±0.07-8.92±0.06%, protein content of 83.38±0.06 -91.11±0.03%, and the ash content 0.53 ± 0.04 to 1.23 ± 0.09%, respectively. Based on the spectra absorption of infrared were detected four areas amides: amide A (3402.43-3448.72 cm-1), amide I (1635.65 cm-1), amide II (1527.62 cm-1) and amide III (1242.16 cm-1). The differences in the concentration of HCl had impact on yield,characteristics and secondary structure of buffalo hide gelatin. The HCl concentration at 0.9M was the optimum condition to obtain the highest yield. The characteristics of buffalo hide gelatin after pretreatment using hydrochloric acid had met the standards of GMIA (2012).

Abstract

Anoa are fully protected under Indonesian Law since 1931 (Law of Protection of Wild Animals 1931, no134). Increasing law enforcement regarding hunting as well as promoting awareness of the Anoas uniquethreatened the existence of conservation measures. The modern concept of conservation based on thesustainability utilization, and therefore the knowledge of the Anoa preference in feeding to support thesustainability conservation should be studied. In the present study, the combination of direct observationmethods which was done in the Lore Lindu National Park in Toro village at District Kulawi, Central Sulawesiand the epidermal analysis method which was carried out to Anoa’s dung were aimed to identify the vegetationspreferred by Anoa in their habitat. The result showed 28 species of vegetations was used as feed by Anoaon in situ area. According to its percentage, the first ten were Freycinetia insignis Blume (17%), Microlepiatodayensis Christ (8.9%), Disoxylum sp (8.6%), Lasianthus clementis Merr (7.7%), Clusia sp (7.5%),Schleria sp (6%), Podocarpus imbricatus (5.4%), Smilax leucophylla (5.1%), Elastostema sp (4.2%),and Garcinia sp (3.8%), respectively. Furthermore, it can be concluded that Anoa was eat more leafs andshrubs/bushes (each 24%, respectively) compared to flowers (18%), fruits (12%), shoots (8%), grasses,tubers, young grooves (each 4%, respectively) and moss (2%). Nutritionally, Anoa consumed 8.8% proteinand 25.6% crude fiber.
