Abstract/ Executive Summary:

Reproductive diseases of crossbred dairy cows significantly reduce productivity which is of great concern of dairy producers worldwide. The objectives of this study were to determine the prevalence of reproductive diseases and its associated risk factors in crossbred dairy cows in selected areas of Bangladesh. The study was conducted at eight villages of Ullapara Upazila under Sirajganj district. A total of 197 dairy farms having 488 breedable crossbred dairy cows (395 cows + 93 heifers) were randomly selected. A questionnaire as well as examination of cows was made to collect data on occurrence of reproductive diseases. The overall prevalence of reproductive diseases was 39.4%. Among the diseases, post calving anoestrus was 8.6%, delayed puberty was 6.8%, repeat breeding was 5.7%, retained placenta was 4.7%, metritis was 3.9%, dystocia was 3.3%, vaginal prolapse was 2.7%, abortion was 2.1% and uterine prolapse was 1.6%. The body condition score (BCS) of cows significantly (P<0.05) influenced the occurrence of reproductive disease. However, feeding practice, suckling, milk yield and parity did not influence significantly (P>0.05) the occurrence of reproductive diseases in crossbred dairy cows. In conclusion, further studies are needed with more number of cows to confirm the findings.

Commodity: Cow

Objectives:

To investigate the prevalence of reproductive diseases and its associated risk factors in crossbred dairy cows in selected area of Bangladesh.

Methodology:

A total of 197 dairy farms having 488 crossbred dairy cows (395 cows + 93 heifers) were randomly selected in eight villages of Ullapara Upazila under Sirajganj district during the period from December 2012 to April 2013. The villages were Mohonpur, Aliapur, Vangri, Changtia, Dharail, Nandakusha, Mordoho and Boyra where Community-based Dairy Veterinary Foundation (CDVF), Bangladesh Agricultural University, Mymensingh has been providing services to the farms. Farmers housed their cows in traditional houses. Most cows were fed with straw, green grass and little concentrate with free access to water. Farmers practice routine deworming and vaccination against FMD and Anthrax. The cows are milked by hand milking keeping calves at feet of the cows. A questionnaire was prepared according to the objectives of the investigation and was designed in a simple way so that the farmers could understand easily. The questionnaire included questions to collect information of age, breed, BCS, respiration, pulse, temperature, feeding practices, reproductive diseases, other diseases, age at puberty (month), parity, last calving date, service needed for previous pregnancy, date of first service after last parturition, date of last service, type of service, pregnancy period (month), service needed for present conception, number of service given, problem at last pregnancy, problem at parturition, suckling and milk yield. The data were collected directly from owner of dairy farms by interviewing, by examination of records, if any, and by examination of animals and sheds. Information was collected on all breedable animals (cows that calved 60 or more days before but did not conceive and heifers those are 24 or more months old but were not pregnant) and pregnant cows. Cows seemed to suffer from delayed puberty, repeat breeding, post-calving anoestrus and metritis was examined by per rectal palpation of genital tracts to confirm the diagnosis.

Achievement/Findings:

The present study reveal that the overall prevalence of reproductive diseases in crossbred cows is 39.4%. Major diagnosed reproductive diseases are post calving anoestrus, delayed puberty, repeat breeding, retained placenta, metritis, dystocia, vaginal prolapse, abortion and uterine prolapse. BCS of cows significantly influences the occurrence of reproductive disease. Feeding practice, suckling, milk yield and parity do not influence the occurrence of reproductive diseases. Further studies are needed with more number of cows to confirm the findings.
