“…Considering the biological limits and economics of the operation involved, many workers in tropical and sub-tropical regions have set a range of 40-60 days as an optimum dry period for the perspective of cow's health and farmer's profit. The findings of estimated DO was higher than 85.6±5.6 days reported in Asella town, Oromia regional state, Ethiopia [12] and 2.9 ±3.7 months reported in crossbred cattle in and around Gondar, North Western Ethiopia [13]. Shorter DO of 148±1.72 days reported in dairy cows in urban and peri-urban dairy production system of Addis Ababa milk-shade [14] and 5.19±1.72 months in Zebu X Holstein-Friesian crossbred dairy cows in Jimma Town, Oromia, Ethiopia [2].…”

“…Therefore, the CI, as seen in this study, suggest a large need for future improvement. Higher CI of 372.8 days reported in Asella town, Oromia regional state, Ethiopia [12] and 13.4 ±5.1 months in crossbred cattle in and around Gondar, North Western Ethiopia [13]. This estimated CI in this study was less than 21.36±3.84 months in Zebu X Holstein-Friesian crossbred dairy cows in Jimma Town, Oromia, Ethiopia [2], 487 days in crossbred dairy cows in different production systems in the central Highlands of Ethiopia [18]; 552 days in Boran cattle and their Friesian crosses at Abernossa Ranch, Ethiopia [19] and 475 days in crossbred cattle in Central Ethiopia [20].…”

The study was conducted on altogether 411 milch animals comprising of 172 indigenous and 239 Holstein-Friesian (HF) crossbred cows maintained under farmer's managemental system in and around Gondar (Ethiopia). Collected data were analyzed according to Least Squares Analysis to study the magnitude as well as direction of variation in their days open (DO), calving interval (CI) and number of services per conception (NSC) due to genetic and some non-genetic factors. The overall Least Squares Means for DO, CI and NSC were estimated to be 116.5242.51 days, 439.0366.34 days and 1.80.3 respectively. The genetic constitution of the animals influenced DO, CI and NSC significantly (P<0.01). Location of herd had also significant (P<0.05) effect on DO, CI and NSC. Lactation order had significant (P<0.01) effect on CI and NSC. Its effect on DO was also found to be significant (P<0.05). Variations in all the traits due to herd-size, season of calving and farming system were statistically non-significant.

“…Both farm size and calving season were not significantly correlated to AFC. The current finding is comparable with the previous studies by [16][17][18] who have reported 34.8 ± 4 months of mean AFC in Assela, 36.4 ± 1.7 months in Mekelle and 34.8 months in Asella, respectively. The mean AFC obtained in this study was higher than most of the reports including 18.7 ± 3.5 months in two towns (Bishoftu and Akaki) in central Ethiopia [19], 31.9 ± 0.22 months for crossbred cattle in Ziway [20] and 32.4 [21].…”

The longer calving interval in this study might be related to poor heat detection, poor feeding practices and related managemental factors.…”

This study was conducted to assess the reproductive and productive performances of smallholder crossbred dairy farms in Wolaita Sodo town of Southern Ethiopia. Twelve smallholder crossbred dairy cattle farms were studied longitudinally for two years. Almost all of the farms were intensively managed and basic farm management practices with acceptable animal health and artificial insemination services from the nearby animal health care organization had been practiced. However, professional assisted pregnancy diagnosis and farm animal record keeping were less experienced. The overall means and standard error (M ± SE) of age at first calving, calving interval, calving to conception interval and number of services per conception were 37.5 ± 0.6 months, 518.0 ± 22.5 days, 253.9 ± 22.6 days and 2.1 ± 0.2, respectively. Among independent variables considered in the study only farm size had significant influence on age at first calving (P<0.05). The mean of average daily milk yield, lactation length and lactation milk yield were estimated to be 8.32 ± 0.6 liter, 423.79 ± 16 days and 3534.16 ± 311 kg/cow, respectively. Generally, the observed reproductive and productive indices showed poor performances which are below the recommendations of crossbred smallholder dairy farming in the tropics. Several reproductive health problems were prevalent in the study area with mastitis being the most prevalent. Accordingly, training on managemental aspects of dairy farming and extension services to enhance production and reproduction is needed. Furthermore, detailed investigation is necessary to identify and quantify the factors that affect the reproductive and productive performances.

Reproductive disorders are one of the most important problems that affect the production and productivity of dairy cows. The study which employed both questionnaire and regular follow up was conducted in Dessie and Kombolcha with the objectives of determining the prevalence of major reproductive health problems of dairy cattle and to asses possible risk factors and to forward the possible recommendations to the prevention and control approaches in 22 dairy farms from November 2015 to May 2016. A total of 487 dairy cattle 456(93.6%) cross and 31 (6.4%) local breed which were kept under different management system 444 (91.2%) intensive and 43(8.8%) semi intensive were included, out of which 39.8% (n=194) had at least one of the reproductive disorders. Repeat breeder, Retained Fetal membrane (RFM), anestrous, and dystocia were found to be the major reproductive health problems containing 9.9%, 7.6%, 5.3% and 4.5% prevalence rate respectively and other reproductive health problems observed with lower prevalence include mixed, vaginal prolapsed, abortion and uterine prolapsed having 4.1%, 3.3%, 3.1%, and 2.1% prevalence rate respectively in the study farms of the two towns. The prevalence of reproductive problems showed significant difference (p<0.05) with respect to age, BCS and parity of dairy cows Whereas, breed, management system and place of farm were not found to have a significant influence (p>0.05) on the occurrence of reproductive problems in dairy cows where major reproductive health problems were observed in cross breed and intensive production system as well as in Kombolcha dairy farms. Therefore, it is recommended that awareness creation to farm owners, attendants and improved management such as, proper feeding, accurate heat detection, considering the size of sire and dam while using AI, and health management should be improved to minimize the occurrence of these problems and associated economic losses in the dairy farms of the area
