The objective of the study was to evaluate the effect of Sapindus rarak extract (SRE) with or without garlic extract (GE) on in vitro ruminal fementation. This research was conducted experimentally with a randomized block design, with 7 treatments and 5 blocks. The treatments were: R0: dairy cow feed; R1: R0 + 1.5 ppm Cr + 0.3 ppm Se + 40 ppm Zn; R2: R1 + 1.8 g/kg methanol extract of lerak fruit meal (SRE); R3: R2 + 0.25 ppm of garlic extract (GE); R4: R2 + 0.50 ppm of GE; R5: R2 + 0.75 ppm of GE; R6: R2 +1.0 ppm of GE. The results showed that the supplementation of SRE alone or without GE did not affect the pH, however, it decreased crude fiber digestibility. The supplementations of SRE and GE, decreased crude fibre digestibility as much as 13.01% up to 16.6%. The supplementation of 1.8 g/kg SRE + 0.25 ppm GE in the dairy cattle diet was able to decrease ace-tate, protozoal population and increase propionate. The supplementation of 1.8 g/kg SRE and 0.25 ppm garlic represents the best combination for dairy cattle feed in improving ruminal fermentation based on feed digestibility, fermentation products, and rumen bacterial population.

Coffee husks is an abundant crop residue but the content of anti nutritional substances such as caffeine, tannin, and lignin limit its utilization as feed ingredients. Higher fungi such as Pleurotus ostreatus have the ability to biotransform lignocellulosic materials through their extracellular enzyme activities. This study was carried out to assess the effect of solid state fermentation by using P. ostreatus on nutrient composition of coffee husk and to evaluate its potency as ruminant feed in vitro. The in vitro experiment was conducted to determine fermentability of treated coffee husk. The usage rate of fermented coffee husk was mimicked feeding level to mid lactation dairy cows; 0%, 10%, 20%, 30%, and 40% (R0 to R4). Fermentation of coffee husk by P. ostreatus increased its protein, from 10.36% to 12.14%, and cellulose, from 19.51% to 24.80%, and decreased its lignin, from 65.42% to 45.04%, tannin from 1.02% to 0.18%, and caffeine, from 1.39% to 0.20%, concentrations. There were no differences in ruminal pH and N-ammonia production but volatile fatty acid production and dry matter digestibility decreased as the fermented coffee husk level increased. The ruminal protozoa population in fermented coffee husk diets was lower than the control diets (P<0.05). In conclusion, it is possible to use 20% of fermented coffee husk in the ration.

The research was designed to evaluate chromium incorporation by Ganoderma lucidum in rice straw substrate supplemented with chromium chloride. Treatments were combination of Cr level (0, 500, 1000, 1500, 2000, 25000, and 3000 ppm) and fermentation time (0, 2, 3, and 4 wk). The treatments were arranged in a factorial 7 x 4 and allocated in completely randomized design with three replications. G. lucidum was grown in potato dextrose agar (PDA) medium for 10 days and was inoculated to the substrate which have been sterilized and mixed with CrCl3.6H2O. The moisture of substrate was maintained at 70%. Fiber and protein components of growth media of G. lucidum was determined and analyzed for their Cr content. The finding result showed that addition of Cr up to 3000 ppm into the substrate stimulated the G. lucidum growth. Chromium was incorporated into the fiber and protein components of the growth substrate of G. lucidum during fermentation. Incorporation of Cr into the protein of substrate containing3000 ppm Cr was highest when fermented for 4 wk. Protein component of substrate contained 9.29% Cr while in NDF and ADF was 27.20% and 10.55% Cr, respectively. It is concluded that Cr was incorporated into the G. lucidum cells during fermentation.

Cattle farms resources in NTT are potential to be developed, but regency has not used it effectively. As a consequently, a huge disparity of beef cattle deployment between regencies occur. The objectives of the research were: a) to analyze the level of Capacity of Increasing Beef Cattle Population (CIBCP) in each regency, and b) to analyze the priorities of each regency for the development of beef cattle. Methods of the research used maximum potential of land resources (MPLR) and maximum potential of householder (MPNH) equation to analyze the effectiveness of CIBCP for regency. This analysis used to analyze the capacity and priorities. To formulate the beef cattle development policies, analysis of the ratio of the density of population and livestock are used. Conclusions: (a) NTT has a very large capacity to increase beef cattle to about 3.2 times that of the current population (based on land and labor resources), with the existing technology and management. Regency areas with large land resources and labor generally have a large CIBCP. On the other hand, regions with large land resources but small labor resource (or vice versa), have a small CIBCP (depending on the most limited resources), and (b) Scale of the priority regions are not only dominated by the largest number of cows. The number of households and the cultivated land has positive and powerful impacts (compared to pasture areas) to CIBCP effective.

Spotted buffalo, an exotic species that exists in Tana Toraja, South Sulawesi, Indonesia, is getting extinct due to high number of slaughtered during a funeral ceremony, called Rambu Solo’, as well as special treatments that do not allow the male spotted buffaloes perform natural mating activity. According to that, the research was trying to start conservation program by collected the cauda epididymal sperm soon after slaughtered. Two egg yolk-based extenders with different buffers, tris hydroxyl amino methane (TEY20) and trisodium citrate dehydrate (CEY20), were used as comparison to evaluate the post-thawed epididymal sperm quality and fertilizing capacity in artificial insemination program. The results showed that the post-thawed progressive motility of epididymal sperm was 40% and 39.17%, while viability was 65.99% and 63.26% and membrane integrity was 65.43% and 63.03% in TEY20 and CEY20 extenders, respectively. The success rate of pregnancy was 46.67% using post-thawed epididymal sperm in TEY20 and 40% using the one in CEY20 extenders. In conclusion, tris-based and citrate-based extenders have similar ability to maintain the epididymal sperm quality and its fertilizing capacity.

Transportation may cause stress that affects livestock’s health. This research was conducted to observe the effect of transportation on the profiles of blood cortisol, triiodothyronine (T3), thyroxine (T4) and neutrophil/lymphocyte (N/L) ratio as stress indicators during 15 days post-transportation. Four females swamp buffaloes, 2-yr-old were used in this research. The animals were transported using an open truck, along 15 kilometers distance for 2 h. During acclimatization, the animals were fed grass twice a day and access to water ad libitum. Blood was collected at the time of arrival and everyday for 15 d post-transportation. Cortisol, T3 and T4were analyzed using Radioimmunoassay (RIA) method. Blood smears were also prepared and stained with Giemsa for leukocyte differential counts. Results showed a significant relation (P<0.05) between transport and an increase in cortisol and T4 level on day-1 post-transportation compared to the normal levels. The level of T3 was also increased on day-3 post-transportation. Total leukocyte counts were 8.91-18.83×10³/μL. Neutrophil, eosinophil, monocyte, and lymphocyte counts were 4.87-10.41×10³/μL, 0.66-1.75×10³/μL, 0.11-0.58×10³/μL, and 2.98-6.21×10³/μL, respectively. N/L ratio was 1.23-3.49 with >1.5 in average throughout the period of the research. It is concluded that transportation causes stress and therefore changes metabolic process.

Intestinal defense mechanism against helminthes parasitic nematode to be associated with mucosal mast cells reaction. The aim of this research was to examine the effect of infection by Ascaridia galli parasite to trigger mucosal defense based on mucosal mast cells response in laying hens. Amount of ten head laying hens 12-wk old were divided into two groups containing five chickens of each. The first group, chickens were left as un-infected controls. The second group, chickens were infected orally with 1,000 embryonated eggs of A. galli. Mucosal mast cell responses were assayed by in situ jejunal mast cell counts in stained serial histological sections with Alcian blue (pH 0.3) and Safranin-O (pH 0.1) of the jejunum. Mucosal mast cells response were observed and counted on days 14 post infection. The result showed that A. galli infection was able to increase significantly (P<0.05) mast cells response. This research concluded that the A. galli infection can trigger the involment of mucosal mast cells response in jejunal defense of laying hens against parasitic diseases caused by A. galli.
