Aplikasi pengendalian hayati untuk penyakit parasitik pada Kerbau Rawa di Desa Tanjung Pering Kecamatan Inderalaya Kabupaten Ogan Ilir

One of the problems that occur in buffalo farms in tanjung pering village is that buffaloes often experience health problems caused by parasites. The results of initial observations showed that livestock showed symptoms such as dry skin, hair loss, loss of appetite, lethargy and finally decreased productivity and even death. This disease often appears during the transition from the rainy season to the dry season. Based on the results of research that has been carried out on faecal samples of swamp buffalo in the villages of tanjung pering and tanjung senai, the identification of the presence of parasite eggs of cestode, nematode and trematode. This activity aims to provide knowledge innovation to the farming community in tanjung pering village about the methods and importance of biological control as an alternative to controlling the spread of parasitic diseases. The methods used in this activity are counseling, training in the form of demonstrations and activity evaluations. The results of the extension activities show that there is an increase in the understanding of farmers about the causes and symptoms of the disease, how to handle and biological control of parasites by using the nematophagus fungus. The conclusion of this activity is the existence of continuous application of disease control using biological agents to suppress livestock populations experiencing parasitic infections.

A review chromosome analysis comparison of swamp buffalo (Bubalus bubalis) with different phenotypic characters in East Java, Indonesia

Chromosomal data on swamp buffalo especially in East Java province, is still lacking. For breeders, chromosomal analysis needs to be done to detect the possibility of hereditary genetic defects. In Malang Area, farmers lack of care and breeding programs for swamp buffalo also caused a decline in the genetic quality and performance. The purpose of this study was to compare the results of the chromosome analysis of swamp buffalo in Malang and another area in East Java province, which were selected based on differences in phenotypic characters. Chromosome analysis is very important for breeders because the results of this study can be used as a consideration for strategies to improve the genetic quality of swamp buffalo. The method used is standard karyotyping using whole blood with G banding staining. Chromosomal preparation using Karyo MAX medium, Colcemic Solution, Giemsa Stain, and KCl solution. Cell culture was performed according to the standard karyotyping method in mammals. The minimum number of 5 spreading chromosomes is the best was chosen, microphotographed, and then chromosome analysis is performed using Cytovision Image Analysis software. The results of this study did not find swamp buffalo with an abnormal number of chromosomes in East Java Province, Indonesia.

Reproductive characteristics of female swamp buffalo reared under Kalang production system in South Kalimantan

Swamp buffalo has been an integral component of society in the swamp area in South Kalimantan. The system is characterized by 2-5 farmers rearing herds semi intensively in one shared kalang, a traditional wooden shelter on swamp area. This study was aimed to determine the reproductive characteristics of female swamp buffalo under kalang systems in Hulu Sungai Selatan Regency, The Province of South Kalimantan. The data of reproductive characteristics and farming systems were collected through interviewing 21 farmers in 4 kalang groups who kept 351 buffaloes (153 of them were females). The observed parameters were average of productive females ages, age at first mating, calving interval, post-partum estrus (PPE), percentages of pregnant and lactating cows. Results showed that the average of productive female buffalo ages was 9.9 ± 0.99 years; female swamp buffaloes were first mating at 51.4 months; first calving at 63.4 months; calving interval was 16.5±0.70 months; PPE was 4.9±0.64 month; gestating and lactating cows were 21.6% and 60.1%, of the productive female population, respectively. We concluded reproductive characteristics of female swamp buffalo under kalang production systems can be enhanced through improvements of the production system, including pre-weaning calf management, feed supplementation, and health care practices.

The Cytogenetics of the Water Buffalo: A Review

The water buffalo (Bubalus bubalis), also known as the Asian buffalo, is an essential domestic bovid. Indeed, although its world population (~209 million heads) is approximately one-ninth that of cattle, the management of this species involves a larger human population than that involved with raising cattle. Compared with cattle, water buffalo have been understudied for many years, but interest in this species has been increasing, especially considering that the world population of these bovids grows every year—particularly that of the river buffalo. There are two genera of buffalo worldwide: the Syncerus (from the African continent), and the Bubalus (from the southwest Asian continent, Mediterranean area, southern America, and Australia). All species belonging to these two genera have specific chromosome numbers and shapes. Because of such features, the study of chromosomes is a fascinating biological basis for differentiating various species (and hybrids) of buffaloes and characterizing their karyotypes in evolutionary, clinical, and molecular studies. In this review, we report an update on essential cytogenetic studies in which various buffalo species were described from evolutionary, clinical, and molecular perspectives—particularly considering the river buffalo (Bubalus bubalis 2n = 50). In addition, we show new data on swamp buffalo chromosomes.

Evolutionary Analysis of OAT Gene Family in River and Swamp Buffalo: Potential Role of SLCO3A1 Gene in Milk Performance

The organic anion transporter (OAT) family is the subfamily of the solute carrier (SLC) superfamily, which plays a vital role in regulating essential nutrients in milk. However, little is known about the members’ identification, evolutionary basis, and function characteristics of OAT genes associated with milk performance in buffalo. Comparative genomic analyses were performed to identify the potential role of buffalo OAT genes in milk performance in this study. The results showed that a total of 10 and 7 OAT genes were identified in river buffalo and swamp buffalo, respectively. These sequences clustered into three groups based on their phylogenetic relationship and had similar motif patterns and gene structures in the same groups. Moreover, the river-specific expansions and homologous loss of OAT genes occurred in the two buffalo subspecies during the evolutionary process. Notably, the duplicated SLCO3A1 gene specific to river buffalo showed higher expression level in mammary gland tissue than that of swamp buffalo. These findings highlight some promising candidate genes that could be potentially utilized to accelerate the genetic progress in buffalo breeding programs. However, the identified candidate genes require further validation in a larger cohort for use in the genomic selection of buffalo for milk production.

Biplot Simulation of Length and Circumference of Different Body Regions of Swamp Buffalo (Bubalus bubalis)

Background: Biplot simulation using factor analysis with Promax kappa rotation of 90 is used to determine the coordinates of the length and body circumference dimensions of male and female mud buffalo in two-dimensional space. So that it can be known which body dimensions have fast, medium, and slow growth rates, and also to find out at what age male and female buffalo the growth rate is fast or slow. Methods: This study used 3 male and female buffaloes aged 10, 12, 14, 16, 18, and 20 months, so that the number of buffalo used was 36. The data obtained were analyzed using Factor Analysis with Promax Kappa 90 rotation. The object coordinates were the coordinates of male and female swamp buffalo aged 10, 12, 14, 16, 18, and 20 months, determined based on the Analysis Factor Scores Regression. The location of the coordinates of the length and circumference dimensions and the location of the object coordinates of male and female buffaloes aged 10, 12, 14, 16, 18, and 20 months are drawn using a biplot graph. Conclusion: The biplot simulation results show that the body dimensions in quadrant II have the fastest growth rate, namely the length of the horns and the length of the neck, which are body dimensions that are slow to reach adult size. The dimensions of the body in quadrant I are body length, head length, upper and lower neck circumference. While the slow growth rate in quadrant IV indicates that the dimensions of the body are already growing or the growth is not optimal; namely, the length of the ears and the length of the tail have reached adult size. At the same time, the abdominal circumference and chest circumference are due to their growth not being optimal. Based on age and sex, the dimensions of male buffalo's length and body circumference are always greater than that of female buffalo from the age of 10-20 months. The positional distance between male and female buffalo age shows that the older the age, the shorter the distance; this result indicates that the growth rate slows down with increasing age.

Potensi Jangkauan Wisata Harian Berdasarakan Analisis Network Sistem Informasi Geografis: Studi Kasus Kabupaten Hulu Sungai Utara

Hulu Sungai Utara Regency has a tourism mainstay of the province, swamp buffalo, which has attracted many national and international tourists. As one of the great tourist magnets, swamp buffalo tourism is not yet supported by other attractions, so tourists tend to only visit one object and leave immediately. Hulu Sungai Utara Regency has other potential tourism objects, but with a wide landscape and not optimal tourism conditions, it is necessary to plan tourism routes with daily reach. This research uses quantitative methodology with network analysis and application assistance of ArcGIS, finding the optimum route as the basic daily reach of travel. As a result, analysis of the optimum route selection results in the main tourist area as a tour package from a collection of all tourist themes (natural, religious, historical, cultural and shopping) that can be reached by a tour package for 2 days, while tourism with a natural theme can be taken 1 day by 3 package options, as well as religious tourism that can be reached within 1 day
