“…In Ethiopia, the distribution of BTB in animal populations has long been described [ 8 ] and most studies also showed that BTB is prevalent mainly in cattle in wide areas of the country [ 9 – 11 ]. Absence of regular surveillance or any control measure strategies in the country aggravates the widespread and endemicity of BTB and being a threat to public health [ 12 , 13 ]. In Ethiopia, different studies conducted so far on animals are based mostly on slaughterhouse reports made by researchers and veterinarians investigating gross tuberculous lesions of BTB, and also through the use of skin tuberculin testing [ 14 ], with a prevalence ranging from 4.7 to 10.2% for gross tuberculous lesions [ 10 , 15 , 16 ] and 9.7 to 50% when using tuberculin skin testing [ 13 , 17 ].…”

Background In Ethiopia, the distribution of bovine tuberculosis (BTB) has long been known and documented as a major problem of animal health. However, the burden of circulating M. bovis strains is poorly understood in the country. Therefore; this study aimed to identify and characterize the mycobacterial isolates responsible for BTB in Northwest Ethiopia. Methods A cross-sectional study was conducted on tuberculous lesions that had been collected from slaughtered cattle between September 2018 to June 2019. Collected lesions were cultured and tested for tuberculous bacilli. The MPT64 assay and Genotype line probe assay (LPA) were used for identification of mycobacterial isolates, and region of deletion 4 (RD4) typing and spoligotyping were used to characterize the M. bovis strains. Results Of the total 1458 examined slaughtered cattle, only 62 (4.3, 95%CI; 0.0328–0.0542) had tuberculous lesions. The highest number of gross tuberculous lesions were observed from the lymph nodes of the thoracic cavity; at the mediastinal (40.3%, 25/62) and bronchial (22.6%, 14/62) lymph nodes. Of the 62 collected tuberculous lesions; 18 (29.0%) were culture positive for mycobacterium isolates, and only five isolates were confirmed for M. tuberculosis complex (MTBc) by the MPT64 assay and LPA. All the five MTBc isolates were positive for RD4 typing of M. bovis with a PCR product size of 446 bp, and no isolate was noticed to have M. tuberculosis. The detected M. bovis strains displayed five spoligotypes; with the common SB1176 and SB0133 M. bovis strains, although the two spoligotypes had not been previously reported. Conclusion The present study shows that BTB in North Gondar, Ethiopia, is caused by M. bovis strains SB1176 and SB0033, with low frequency. Thus, the finding highlights the importance of continuous surveillance for mycobacterial strains in cattle populations.

Reproductive performance of dairy cattle in terms of age at first service (AFS), age at first calving (AFC), calving interval (CI), day open (DO), and a number of service preconceptions (NSPC) in the different production system in Ethiopia is reviewed. The reproductive performance parameter of dairy cattle like age at first serves (AFS), age at first calving (AFC), calving interval (CI), Day opens (DO), and the number of service preconceptions (NSPC) under different production system is quite different. Age at first calving (AFC) in pastoral and agro-pastoral and intensive dairy production systems were 43.5±1.5months and 33.2 months, respectively. Days open (DO) in pastoral and agro-pastoral, smallholder dairy production, and urban and dairy products for local cows were 141±7 days, 185±51.2days, and 199.8±11.60 days, respectively. 85 to 115days considered as optimum for a dairy herd, 116 to 130 days indicate slight problems, 131 to 145 days moderate problems. This, indicated that days open in the different production system is not within the normal range. Similarly, for cross dairy cows in an intensive dairy production system was157.8 days. The calving interval (CI) in pastoral and agro-pastoral, smallholder dairy production systems, urban and pre-urban for local cows were 14.63±10 months, 14.36± 1.03 months, and 22.17±0.79 months, respectively. Whereas urban and pre-urban and intensive dairy production for cross dairy cows were12.42±5.9 months, 15.820±.41months, and 14.56 months, respectively. NSPC for Horro x Jersey (1.8) and Horror (2.1) are not within the normal range, But for Borana (1.6), Fogera (1.28), Friesian x Zebu (1.56) were within the normal range. This difference might be due to poor management in terms of nutrition, health care, housing, heat detection, timely insemination, and breeding as well as environmental factors. It could be concluded that proper management in terms of nutrition, health care, housing, heat detection, and timely insemination would improve reproductive performance under different production systems. Besides this, to boost dairy cattle reproductive performance, intensification of dairy cattle production should be promoted in Ethiopia to meet the increasing demand for dairy products and to reduce imports of dairy commodities. Thus, all coordinated works of all concerned bodies should be in place to boost production and productivity and thereby enhance the livelihood of the dairy farmers.

“…However, some businessmen and retired civil servants also keep some dairy animals depending, wholly or partly, on hired labor. Producers are market oriented and respond to improved technical, input supply and marketing services (Bogale et al, 2014).The main feed resources are agro-industrial by-products, purchased roughage, crop residue and pasture land. The primary objective of milk production is generating additional cash income (Aneteneh et al, 2010) Mixed crop-livestock Dairy production system Mixed crop-livestock dairy production is a subsistenceoriented farming system concentrated in the mid-and high-altitude agro-ecological zones where cereals and cash crops are dominant farm activities.…”

Reproductive performance of dairy cattle under different production system was reviewed in Ethiopia. The reproductive performance parameter of dairy cattle like age at first serves (AFS), age at first calving (AFC), calving interval (CI), Day opens (DO) and number of service per conception (NSPC) under different production system was quite different. Age at first calving was in Pastoral (43.5±1.5) months, Agro-pastoral (43.5±1.5) and Urban (33.2±0.79) months. Days open, for local breeds were in Pastoral (141±7 days), Agro-pastoral (141±7 days) and urban (185±51.2. The calving interval for local breed were in pastoral (14.63±10 months), agro-pastoral (14.36± 1.03 months) and pre-urban (22.17±0.79 months) whereas for cross dairy cows were, urban 14±0.56 months, pre-urban 15.820±.41months and intensive12.42±5.9 months. The number of service per conception were for Horro x Jersey (1.8), Horro (2.1) Borana (1.6), Fogera (1.28), Friesian x Zebu (1.56), respectively. This difference was due different production system. It could be concluded that proper management in terms of nutrition, health care, housing, heat detection, timely insemination would improve reproductive performance under different production system. Beside this, to boost dairy cattle reproductive performance, intensification of dairy cattle production should be promoted in Ethiopia to meet increasing demand for dairy products and to reduce imports of dairy commodities. Thus, all coordinated works of all concerned bodies should be in place to boost the production and productivity and thereby enhance the livelihood of the dairy farmers.
