Industrial food animal production uses huge amounts of antibiotics worldwide. Livestock, their excreta used for manure and meat subproducts not intended for human consumption can all play important roles in the transmission of bacterial resistance to wildlife. Vultures and other scavengers can be directly exposed to active antibiotics ingested while feeding on livestock carcasses. This study evaluates whether bacterial resistance in the red kite (Milvus milvus) differs between two wintering areas selected based on patent differences in farming practices—particularly in the industrial production of food animals (primarily swine and poultry) vs. scarce and declining sheep herding. The results support the hypothesis that intensification in food animal production is associated with increased bacterial multidrug resistance in wildlife. Resistance was positively correlated with time elapsed since the beginning of the commercial application of each antibiotic in human and veterinary medicine, with clear differences depending on farming intensification between areas. Monitoring programs are encouraged to use red kites and other avian scavengers as valuable sentinels of contamination by antibiotics and clinically relevant resistant pathogens from livestock operations of variable intensities. Farms authorized for supplementary feeding of threatened scavengers should avoid supplying carcasses with active antibiotic residues to avoid bacterial resistance in scavenger wildlife.

Background: Punjab being a productive state in agriculture and livestock farming, various institutions are actively involved in Self Help Group formation for socio- economic development of low-income group. Rural women are engaged in small-scale entrepreneurship programme with the help of Self Help Groups. The present study was conducted to assess the impact of livestock based Self Help Groups on knowledge level regarding the scientific livestock farming practices among the beneficiaries of Self Help Groups and non-beneficiaries. Methods: The study was undertaken in Ludhiana district of Punjab. A multistage random sampling procedure was applied to draw the sample for the study. For meeting the objective; 120 beneficiaries and 60 non-beneficiaries were subjected to structured interview schedule. Result: The study revealed that majority of the beneficiaries (50.00%) and non-beneficiaries (55.00%) had medium level of knowledge regarding overall scientific livestock farming practices. Knowledge Index was higher in case of beneficiaries (61.46) than that of non-beneficiaries (56.68). Self Help Groups had made a significant positive impact on knowledge level of the beneficiaries and thus helped in improving overall socio-economic conditions of the rural women.

Leptospirosis in cattle has important economic effects on the infected farms. Moreover, livestock farming is considered a major occupational risk factor for the transmission of Leptospira infection to humans. A survey was performed to determine the overall and within-herd seroprevalence and mapping of different Leptospira serovars in dairy cattle from farms located in some municipalities of the Colombian department of Boyacá. Nine hundred and fifty-nine animals, from 20 unvaccinated and one vaccinated herd, were included in the study. Anti-Leptospira serum antibodies were detected by the microscopic agglutination test (MAT). Only one herd was seronegative. Overall seroprevalence to at least one serovar of Leptospira was 24.1% for unvaccinated animals and 62.3% for animals from the vaccinated herd. A very high within-herd seroprevalence (>60%) was present in 20% of the unvaccinated herds. The presence in the vaccinated herd of 20/398 animals showing high titers, between 1000 and 4000, to at least one serovar of Leptospira suggest that some animals could have been infected. Moreover, due to the presence of seronegative animals, a failure of vaccination immunity or the presence of unvaccinated animals in the vaccinated herd cannot be excluded. In all farms, domestic animals other than cattle were present. Considering the farming practices occurring on dairy farms in the study area, higher hygienic standards and stricter biosecurity measures are suggested.

The U.S. Department of Agriculture last delineated the regional boundary of the Corn Belt in 1950. Mixed-grain and livestock farming practices have today transitioned to annually rotating corn and soybeans, which has altered the geographic bounds of this region. To illustrate the changing geography of the Corn Belt, ArcGIS geoprocessing and spatial analysis tools, along with a simple, summative assessment using Census of Agriculture data, were used to map how the region's boundary has changed as myriad internal and external driving forces influence where farmers grow corn. Since 1950 the region's core has remained spatially stable as corn production has intensified, while the region's periphery has shifted to the northwest. The methods used to create this contemporary Corn Belt region illustrate how a regional boundary and internal regional intensities can be used to map agricultural land use change.

Abstract COVID-19, caused by a newly discovered strain of coronavirus (SARS-CoV-2), has had a significant impact on many sectors at the global, regional, and national levels, including the livestock sector. Study Methods: A questionnaire survey and observational study were carried out from September 2020 to November 2020 with the aim of assessing the impacts of COVID 19 on livestock farming practices, market chain, consumption of animal products, and animal health care services in selected districts of East Wollega zone. Small scale farmers, abattoir workers, consumers, and private sectors involved in the production, processing, and distribution of livestock products, and veterinarians were purposively selected for this study. Based on the survey, 365 (91.25%) respondents agreed as the pandemic was the major challenge to livestock farming practices. The assessment shows that COVID 19 created worst 270 (67.5%) and high impact 75 (18.75%). The major reasons mentioned were measures taken by the government such as lockdown, economic decline, low number of manpower due to calls to stay at home, and social distance. Observational studies indicated that dairy shops, meat shops, and local abattoirs, hotels, and restaurants were totally/partially closed, especially during the first 6 months of the pandemic. The average monthly income from livestock and their products showed about 60.93% shortfalls (from 1,130,500 birr to 688,800 birr). Regarding consumer perception, there was low demand for livestock products mainly due to the perceived disease risk. The most important animal health constraints during this pandemic were unusual preventive practices such as lack of vaccination and deworming, scarcity of drugs at the veterinary clinic, low number of veterinarians and inability to cover the cost of drugs and personnel. The present study suggests that the pandemic's impact on the livestock production, product supply chain and animal health services might be continue, which will have a significant effect on the sustainability of livestock production systems and the contribution of livestock subsectors on the household and national economy and global food security. It is therefore, essential that the government and other concerned bodies should give attention to the livestock sector to mitigate the impacts of the disease.
