“…The prevalence rate of abortion 1.66% recorded in this study is similar to the 2.23%, 2.56%, and 2.9% reported by Bekana et al [ 25 , 19 ] and Tulu and Gebeyehu [ 16 ] in Ethiopia, respectively, and lower than 5.68% reported by [ 26 ] in dairy cattle, India; 6.32% reported by [ 15 ] in chauries of Nepal; and 8.16% reported by [ 27 ] in cattle of Bangladesh. The differences in abortion prevalence can be attributed by various factors such as breed, management systems (especially feeding and standard practices), overcrowding, and intra-group aggression leading to traumatic abortions [ 28 ].…”

Cow is the national animal of Nepal, yet it is one of the most abused animal species here. Under realized utilities of cow that is nonlactating or pregnant is the reason for demonic cruelty. Since the Vedic period, gaushalas have been caring for cows. At present, most gaushalas have responsibility to rescue, offer refuge, and treat poorly treated or confiscated cattle from smuggling rackets in Nepal. It is no surprise that these abused animals suffer from many health issues and compromised reproductive ability. This study was conducted to know about husbandry practice and to determine prevalence of reproductive disorders in cows of Gaushala from Nepal. Altogether, 27 gaushalas were visited throughout the study period and cows (≥2 years) (n = 2959) were included for the study. From the study, respondents from 14.81% Gaushala admitted indigenous cattle only, 11.11% admitted any breed (indigenous and crossbreed), 44.44% admitted stray animals only, and 29.63% admitted all types (indigenous, crossbreed, and stray animals). The study revealed that among (n = 2959) animals examined, 5.54% (n = 164) were affected by either one or more reproductive problems. The major reproductive disorders identified in study area were repeat breeding 0.47%, cervico-vaginal and uterine prolapse 0.34%, retention of placenta 2.13%, dystocia 0.61%, and abortion 1.66%. Herd size of Gaushala had a significant difference (P<0.05) on the overall prevalence of reproductive problems in cows of Gaushala. The main issues with gaushalas included a lack of resources like adequate fund, feeds, fodder, and water, shortage of grazing acreage, veterinary services, and difficulties in managing male cattle. To mitigate the issues and welfare related to gaushalas strict adherence to disease surveillance and biosecurity rules, avoidance of unlimited reproduction in cows, and separation of males and females, fund raising and resource management, collaboration with local government and NGOs, veterinary hospital, clinics, research, and innovation with veterinary institution and universities.

This study investigates the environmental and food security implications of livestock abortions and calf mortality in Tanzanian dairy systems and Kenyan beef systems by utilizing data from previously published studies. The environmental impact of livestock abortion is assessed in Tanzanian dairy systems, examining indigenous and exotic breeds of cattle and goats in Northern Tanzania. Calf mortality’s impact is evaluated in Kenyan beef systems, involving local cattle breeds in western Kenya. Greenhouse gas (GHG) emission intensity (EI) is estimated for both countries. The GHG emissions in Tanzania consider enteric fermentation, manure management, and feed production in different cattle and goat groups, as well as total milk production. In Kenya, enteric methane (CH4) EI related to calf mortality is assessed by estimating lifetime enteric CH4 emissions and total carcass production from dams and their offspring. The EI is compared between the observed scenario (16% calf mortality) and alternative scenarios (8, 4, and 0% calf mortality). A life cycle assessment using the Global Livestock Environmental Assessment Model-interactive (GLEAM-i) examines GHG sources and potential tradeoffs. Estimates are made for milk and carcass losses due to abortions and calf mortality, scaled to represent the entire country. Abortion increases milk EI by 4–18% in Tanzania, while Kenya’s EI ranges from 25.9 to 27.6 kg CO2 eq per kg carcass weight. Animal protein loss due to abortions is equivalent to the potential annual animal protein requirements of approximately 649 thousand people in Tanzania, while a 16% calf mortality rate in Kenya is equivalent to per capita consumption of 4.5 million people. The findings highlight the significant impact of abortions and calf mortality on GHG emissions and animal protein availability, emphasizing the potential for reduced emissions and improved food security through mitigation efforts. The contribution of emissions from enteric fermentation and manure management is significant across both countries, underscoring the importance of a systems perspective in evaluating the environmental impact of livestock production. This study provides insights into the environmental and food security implications of livestock abortions and calf mortality in Tanzania and Kenya, emphasizing the need for targeted interventions in sustainable livestock production.
