Abstract

This study aims to calculate the estimated economic losses in national poultry farming in Indonesia that are infected with pathogenic Escherichia coli. Poor management of chicken preservation is a major predisposing factor. Escherichia coli is a normal flora found in the gastrointestinal tract of chicken, but when the chicken stress or decrease immune system, Escherichia coli develops into a pathogenic agent. Pathogenic Escherichia coli appears as secondary infections that aggravate other disease infection. Cost of illness approach was divided into two main categories namely direct losses from disease and indirect losses from other related costs. Direct losses in broiler farms that were infected with pathogenic Escherichia coli through calculation of weight loss of harvest and total mortality, while in layer farms that were infected with pathogenic Escherichia coli, direct loss calculations included decreased chicken egg production and total mortality. Indirect losses on broiler and layer farms included calculation of other expenditure costs at the time of the occurrence of pathogenic Escherichia coli infections such as cleaning, disinfection and labor compensation costs. Based on the total calculation results obtained that the estimated economic losses incurred on national scale broiler farms reached IDR 14,167,792,041,150, - per harvest period of broiler, while estimated total loss of layer farms on national scale based on the calculation results reached IDR 13,391,996,617,850, - per month. The overall total loss due to this colibacillosis reached 13.10% of total poultry assets in Indonesia. The large proportion of losses incurred to total livestock assets can indicate how important the disease is to be controlled or overcome.

Abstract

The purpose of this research was to determine the effect of heat stress on thermoregulation, haematology, and productivity of Holstein Friesian (HF) dairy cows raised in different elevations. A total of 63 HF in a normal lactation period were used in this study. The research was conducted for 3 months during dry season in three different areas, which were at Pondok Ranggon (97 m.a.s.l) which categorized as a lowland, Ciawi (576 m.a.s.l) which categorized as a lower-upland, and Lembang (1241 m.a.s.l) which categorized as an upland. Observation on microclimate aspects which includes environmental temperature (Ta), relative humidity (RH) and Temperature-Humidity Index (THI) was done by recording each variable for every 2 hours starting from 08.00 to 16.00 WIB. The thermoregulation analysis was done based on the given physiological responses which consisted of the skin temperature (Ts), rectal temperature (Tr), body temperature (Tb), heart rate (Hr), respiratory rate (Rr), Heat Tolerance Coefficient (HTC), plasma cortisol level and haematological profile observation. The Ta, Rr, and THI measurements showed that in the lowland and lower-upland, the HF experienced moderate heat stress, while the HF raised in the upland area experienced less heat stress. The results showed that the dairy cows which raised in lowland had the highest HTC, Tr, Ts and Tb (P<0.05) and lowest Hr (P<0.05). All of the physiological and haematological parameters in the three study area showed a normal value.Furthermore, the erythrocyte, Hb and PVC concentration in a lowland raised HF were higher (P<0.05), while the plasma cortisol levels were not significantly different. The milk production of the observed dairy cows in different elevations was significantly different (P<0.05), with the highest milk yields, were found in the upland raised HF (13.1±3.52 kg), followed by the lower-upland (11.3±4.73 kg) and lowland (7.0±3.36 kg). In general, all of the HF raised in different land elevations was exposed to heat stress during dry seasons, even though the cows showed the ability to physiologically adapt and cope with the conditions.

Abstract

This study aimed to determine the genetic diversity among three duck populations (Bayang, Pegagan, and Pitalah) reared in Sumatera island, Indonesia, using microsatellite markers. Genetic diversity among populations (n = 90) was determined using 22 microsatellite markers, based on several indices: number of alleles (Na), observed heterozygosity (Ho), expected heterozygosity (He), polymorphism information content (PIC), and Wright’s F-statistics ( ). The total number of alleles detected across loci was 121. The Na per locus ranged from 2 (APH24, CAUD128, and CAUD009) to 18 (CAUD048 and CAUD040). The mean Ho (0.429) dan He (0.509) indicated that the level of genetic diversity among populations was moderate, while the mean PIC (0.46) suggested that the tested loci were informative for assessing genetic diversity. The mean F-statistics ( ) were 0.148, 0.198, and 0.060, respectively. The  value indicated that the level of genetic differentiation among populations was moderate. The results confirms a moderate genetic diversity among populations, which could be beneficial for designing conservation and utilization of the local ducks in Sumatera island.

Abstract

This study aims to estimate the carrying capacity of oil palm plantations with the use of herbicides based on the forage availability for Bali cows. The research was performed in palm oil plantation owned by PTPN V Riau, from March 2016 until March 2017. The parameters observed were 1) Forage production that grows between palm trees at 6 weeks cutting age. The forage sample was taken from 5 point of 1x1m2, then subjected to proximate analysis. Data were analyzed with one-way random design, 2) Forage consumption; obtained by observation of 5 pregnant Bali cow and 7 non-pregnant for seven consecutive days 3). Estimated carrying capacity for Bali cows, obtained from the calculation of forage production (/ha/year) divided by forage consumption. The result of the research showed that 1). The production of dry matter (DM) forage in herbicide-treated areas was 689.55 kg/ha/year, not significantly different compared to untreated areas (622.33 kg/ha/year). Crude protein (CP) forage content of forage obtained from herbicide-treated area was significantly higher (p<0.05) than untreated area, whereas the total content of DM and total digestible nutrients (TDN) was not significantly different. DM consumption of pregnant Bali cow was on average 3.68±0.29 kg/head/day or 1,343.20±105.85 kg/head/year and non-pregnant 4.02±0.36 kg/head/day or 1,467.30±131.4 kg/head/year. The estimated carrying capacity on herbicide-treated (0.51 head of pregnant cow/ha), did not show any significant difference compared to untreated area (0.46 head/ha). For non-pregnant, the carrying capacity of herbicide-treated area (0.47 head/ha) was not different with non-treated area (0.42 head/ha). It was concluded that the use of herbicide on palm oil plantation had no effect on the carrying capacity of the Bali cow.

Abstract

The Thyroglobulin (TG) and Leptin (LEP) genes are two candidate genes that widely used for molecular selection to improve carcass traits in beef cattle. This research was carried out to identify the genetic characterization of TG and LEP genes from 47 heads of Pasundan cows at West Java using PCR-RFLP method. Research shows that TG gene of Pasundan cattle is monomorphic with C allele as the dominant allele (1.00). However, LEP gene of Pasundan cattle is polymorphic with C allele as the dominant allele (0.98) and T as the rare allele (0.02). The polymorphic informative content (PIC) and numberof effective allele (ne) values in the LEP gene in the animal studied were 0.04 and 1.04 respectively. It was concluded that TG/BstYI and LEP/Sau3AI gene in the present study can not be used as molecular selection in Pasundan cattle. These results are important as the basic information for preparing the molecular selection program in the future.

Abstract

This study aims to evaluate the age of off-odor detection to ensure more efficient and economical provision of antioxidants in the production of Cihateup ducks. This study used a Completely Randomized Design (CRD) with 3 different treatments of slaughter age, i.e. 4, 8 and 12 week. Each treatment consisted of 6 replications and each replication consisted of 13 ducks. The results showed that the percentage of fat content at the age of 12 weeks was higher than the age of 4 and 8 week. High fat-containing meat tends to undergo fat oxidation. High levels of Fe at 12 week of slaughter age cause high levels of myoglobin in duck meat. Fe2+ is a catalyst in the process of fat oxidation. the brightness value (L) is inversely proportional to the value a of Cihateup duck meat. The darker brightness of the meat causes the flesh to be redder due to myoglobin level in duck meat. The percentage of polyunsaturated fatty acids (ALTJG) is 4- and 12-week slaughter age lower than 8 week of age. The high levels of MDA at 12 week of slaughter age are due to fat oxidation which causes off-odor. Based on the result, the conclusion is that the high fat content, Fe content, color of Cihateup duck meat at 12 weeks of slaughter age caused the percentage of polyunsaturated fatty acids (ALTJG) to be low due to fat oxidation. Fat oxidation caused high levels of MDA in duck meat (12 weeks of slaughter age) resulting in Off-odors in Cihateup duck meat.

Abstract

   The aim of this research was to examine the microbiological quality of calf starter pellet added with fermented cabbage waste after stored for 0, 4, and 6 weeks. The materials used in this research consisted of cornmeal, rice bran, soybean meal, molasses, mineral mix, and fermented cabbage waste. This research used Completely Randomized Design with 4 treatments and 3 replications. The mixed calf starter pellet consisted of 100% calf starter and 6% of fermented cabbage waste, and then stored for 0 weeks (P0), 2 weeks (P1), 4 weeks (P2) and 6 weeks (P3). The observed microbial qualities were the total lactic acid bacteria and the presence of gram positive and negative bacteria in the mixed calf starters. The total lactic acid bacteria were analyzed descriptively, while the presence of gram bacteria was analyzed with analysis of variance followed with Duncan’s test. The result of this research showed that an increase in storage time would result in lower lactic acid bacteria population, while the gram-positive and negative bacteria was not significantly affected. The research concluded that 6-weeks stored calf starter pellet added with 6% of fermented cabbage waste could maintain its lactic acid and gram-positive bacteria population, while also reducing its gram-negative bacteria population as well.
