Abstract

Ethiopia has the largest livestock population in Africa, which is contributing to the economy andforeign exchange by exporting animals, hides and skins. Animal Health and Veterinary Services in East Gojam Zone District most of the livestock is mixed with crops. In this study, animal health interventions were mainly identified from 2020 to 2024 in districts located in the zone through secondary data collection. Although bacterial, viral and parasitic diseases can be controlled strategically, the main animal health interventions in the zone include vaccination, deworming, revolving veterinary drug fund and community capacity building. One of the strategies is vaccination and it is an important step to prevent and control various diseases. The performance of various vaccines has been growing year by year and in most districts, they allocate of money more than one million birr to the rotating veterinary revolving fund budget, which prevented diseases from causing huge economic losses to animals due to the problem of drug supply. Deworming has been carried out in all districts through campaigns and interventions based on the local agroecology. In order for these interventions to be successful and sustainable, the leadership and experts at all levels must identify the problems faced each time and monitor the results on animal health, economic benefits and infectious diseasesand take action.

Introduction

Ethiopia is believed to be the first in Africa in the number of animals. It contributes significantly to the country's economy and the livelihood of its people [4]. The sector serves as a key source of foreign exchange for the supply of meat, milk and leather for export [7]. Animal husbandry is an integral part of Ethiopia's mixed croplivestock system. East Gojam zone is big place in Amhara region.The zone has 57% of the region cattle, 23% of sheep, 13% of goats and a share of horses, mules and donkeys. These species are well adapted to the local agro-ecology [13].

Animal husbandry is an important source of animal protein, for crop cultivation, transportation, export goods, agriculture, household energy and as protection during crop failure. In the year It accounts for40% of agricultural GDP, nearly 20% of domestic and 20% of foreign exchange earnings in 2017 [16].

Animal health services are critical to the diagnosis and control of food borne diseases, ensuring food safety and protecting animal health. A strong veterinary system prevents or reduces risks in primary production and promotes responsible use of animal products to reduce drug residues in animal feed [12].

Animal health services include regional diagnostic laboratories, district clinics and rural health posts. Private Clinics: NGOs and Community Animal Health Workers (CAHWs) support these services. Rural clinics are staffed by one or two veterinarians who provide treatment, vaccinations, spaying and assistance. Treatments usually include simple injections, drenches and wound dressings [9].

Challenges in Animal Health Services Animal diseases are widespread in agro-ecological zones, causing economic and social losses [3]. Many communities depend on livestock for their livelihoods but veterinary services remain inaccessible in highlands, lowlands and midlands. Major challenges include: lack of access to veterinary care, especially in remote areas, limited private and public veterinary services, drug resistance, inadequate quality control, poor disease reporting and uncoordinated research efforts. Proposed Solutions to improve veterinary services, Ethiopia should do the following:

Privatize veterinary services to increase efficiency: encourage community-based animal health programs to enhance disease prevention; introduce mobile veterinary clinics to reach rural areas; strengthen disease reporting and research to improve policies; promote regional collaboration for better veterinary services [3].

Prevention and control of animal diseases strengthening animal health systems can improve animal productivity, food security and trade to protect public health. Prevention of animal diseases requires the implementation of effective vaccination programs, improved veterinary services and capacity building measures [10].

The results of this evaluation inform the necessary interventions of government bodies and stakeholders to overcome the problems in the provision of animal health services in various districts of the East Gojjam zone, especially in controlling and preventing animal diseases.

General objectives

In order to increase animal production and productivity and to prevent public health from animal diseases, the research on veterinary medicine delivery is focused on identifying the activities and interventions in animal health care in East Gojam zone in Amhara region.

Specific objectives

1. To evaluate the types of vaccines given every year to control major animal diseases.

2. To analyze trends in vaccination coverage in the last five years.

3. To identify the months in which vaccination is given to different animals in the East Gojam zone and to evaluate the months in which vaccination is given in abundance.

4. To assess the cost recovery of the revolving fund of veterinary drug in each district

Approaches and Methodologies

Approach

Participatory research methods are presented based on the research framework of the mixed crop farming system involving the farmers' community and other stakeholders. The basic principle of this system is based on the participation of farmers in the evaluation and planning of their needs using a multidisciplinary approach and it correctly acknowledges the involvement of different stakeholders in the progression of animal health services development [2,8].

Accordingly, in the East Gojjam zone, this settlement in order to conduct system analysis, interdisciplinary research and research were conducted with veterinary service delivery system experts.

Survey Design and Data Collection

The study employed a mix of qualitative survey techniques and tools to generate data from primary and secondary sources that served its purpose. Prior to the implementation of field research, an extensive desk review was conducted to identify critical data gaps that served as input for designing survey instruments for primary data collection.

As well as the evaluation of secondary data to confirm the results of the qualitative research report. It should be noted that writing was an important part of the process. The research work is carried out by published and unpublished documents of the Ethiopian Agricultural Research Institute, the Central Statistics Authority (CSA) and the Ministry of Agriculture, other governmental and non-governmental organizations. A review of some major secondary data includes scientific papers; Amhara Agricultural Research Institute, Unpublished documents of East Gojjam Zone Livestock Breeding Office and Related Investigative Breeding System Research Reports. After the first extensive table evaluation work, the research team in animal health developed important semi-structured survey instruments covering service and supply issues affecting the livestock sector.

A field survey (SMS) spanning over five years was conducted to generate primary data from the livestock owner and veterinary practitioner community. A study design was conducted to identify the vaccination coverage and trends in the study area. This was done from data from public and private veterinary clinics in all districts that reported annually to the East Gojjam Zonal Livestock Development Office (EGZODO) from 2020 to 2024. By gathering. The study was designed in consultation with animal husbandry experts of Debre Markos University, Staff and zonal office animals and divided the East Gojjam zone into three levels: plateau (high elevation), plateau (middle ground), and kola (lowland) to show the difference in the natural distribution system. Following the classification of the zones, districts representing the agricultural sector were identified based on expert opinion from the Zonal Livestock Sector Office. Accordingly, Bibune District (Dega), Gozamen, Enmay and Awabel Districts (Wyna Dega); Dejen and Gendwein Districts (Kola) were selected for community-level surveys.

A combination of different qualitative survey techniques, such as key informant surveys (KIS) and field observation was used to generate primary data. The selection of livestock breeding with knowledgeable and experienced farmers was done in consultation with technical experts from various district livestock breeding offices. In addition, the research team conducted a diligent KIS from the Zonal Animal Health Service, Animal Husbandry Member of Debre Markos University and District Level Animal Husbandry Offices.

Data Management and Analysis

Data from the recorded data were stored, filtered, and entered into a Microsoft Excel 2010 spreadsheet and transferred to SPSS version 22.0 statistical software for statistical analysis. Descriptive statistics were used to determine vaccination coverage, which was the ratio of the number of animals vaccinated to the total number of animals recorded annually during the five-year study (2020-2024). Vaccination coverage percentage and trend were shown by line graphs.

Description of East Gojjam Zone

Location and pasture land use pattern: East Gojjam in Ethiopia It is one of the ANRS Management Zones in the Blue Nile Basin. Currently, it is composed of seventeen districts and eight city administrations. The total skin area of the zone is 14,010 square km, which is equivalent to 1.40 million hectares of land [5]. However, data from the Zonal Animal Office indicates that the total land area is 1.46 million hectares, characterized by different grazing land uses. About 45% of Abokut's land is arable, and an additional 8% of irrigated land is suitable for irrigated agriculture. Different forest cover and pasture land account for 13 percent and 11 percent of the total land cover.

Number of Animals

East Gojjam zone is one of the areas with the highest potential for animal husbandry in the Amhara region. The livestock population is estimated to be 2.4 million cattle, 951,982 sheep, 549,778 goats, 31,096 horses, 29,088 mules and 258,407 donkeys, in addition to 1,924,685 poultry and 241,713 bee colonies. The zone has 57% of the total cattle population and 23% sheep, 13% goats, 1% horse, 1% mule and 6% donkey population in ANRS. In addition, the highlands of the East Gojjam zone has nearly 24% of the total horse population in the Amhara region and the regional share of other animal populations is also high, such as donkeys (15%) and mules (12%). Most of the animal species are indigenous with good adaptation to the local agro-ecology [13].

Topography and Agroecology

The East Gojjam zone covers a diverse topography ranging from 800 to 4200 meters above sea level. The maximum Mount Choke, 4100 meter above sea level high, is located in this zone. The detailed topographical features with percentage distribution of zonal slope are clearly illustrated. According to the data obtained from the Zonal Agriculture Office, the topography of the zone traditionally consists of 67.3% flat terrain, 7.8% mountainous terrain and 24.9% steep terrain. The latter is not suitable for agricultural use but due to reported that increasing population pressure, agricultural activities are encroaching on those poor lands. Land degradation is a major environmental problem in those poor areas. It has been pointed out.

Analysis and Accuracy of Survey Results

Animal Health Services Sector: Main Activities, Delivery Methods and Impacts

Animal Health Services Sector in 18 districts in East Gojam zone, the main interventions to prevent and control animal diseases was identified through a survey.

Vaccination interventions: Animal vaccination is the cornerstone of disease prevention, resulting in high efficacy and safety. vaccination strategies vary depending on program objectives and local conditions. Major roads in 18 districts in East Gojam zone include:

Ring Vaccination: It is administered in a radius of 5-10 km to contain the spread. Vaccination activities are dependent on animal density and market activity.

Blanket Vaccination: Mass vaccination is given during a large outbreak to match the cost of vaccination when it causes significant damage to animals.

Targeted Vaccination: Works on high value animals or high risk areas. This works in line with OIE recommendations to monitor virus transmission in unvaccinated animals (10-20%).

Vaccination coverage: The findings of the study show that, from 2020 to 2024, the percentage coverage of anthrax vaccine will increase from 23.6% to 39.6%, 39.2% to 68.4%and 12.8% to 92.8% in cattle, sheep and goats. Found information it shows. And equine, respectively, but in 2024 the anthrax vaccine compared to other consecutive years, it decreased. Because of no peace and as if war, the problem is not being able to vaccinate (Figure 2). The reason for this is due to the decrease in the number of diseases that have occurred in recent years. Blackleg vaccination coverage will increase from 2020 (8.8%) to 2024 (14.7%) but may decrease to 1% in 202 (Figure 3).
