Abstract/ Executive Summary:

Retained placenta is an economically important reproductive disorder which occurs at the end of the reproductive cycle and has repercussions on the next. The study was conducted a total 1205 dairy cows from 9 upazila and 4 Metro Thana of Rajshahi during the period from July 2010 to June 2011. To evaluate the incidence of retained placenta in relation to breed, age, parity and body condition score of dairy cows. A questionnaire was prepared including information viz. name and address of farmer, breed, age; parity and body condition score for achievement of the study. The overall prevalence of retained placenta was 13.4%. The influencing factors including breed, age, parity, body condition score had significant effect (P<0.05) on retained placenta. The highest prevalence was 10.7%, 4.5%, 5.6% and 7.1% observed in cross-breed, > 3 years age, 1st parity and fair body condition group of cows, respectively. From this study, it might be concluded that local breed, ≥ 3 years but less than 5 years age group, 3rd parity had least risk for retained placenta.

Keywords: Incidence, Retained placenta, Age, Parity, Body condition and Dairy cows.

Commodity: Cow

Objectives:

The present study has been taken to evaluate the prevalence of retained placenta in dairy cows on different factors at Rajshahi district in Bangladesh.

Methodology:

The study area and data collection: The study was conducted a total 1205 calvings from 1205 dairy cows from 9 upazila and 4 Metro Thana of Rajshahi. The name of 9 upazilas were viz., Poba, Godagari, Tanor, Mohonpur, Bagmara, Puthia, Durgapur, Bagha and Charghat and 4 Metro Thanas namely Boalia, Rajpara, Motihar and Shamukhdum at Rajshahi district in Bangladesh during the period from July 2010 to June 2011. A structural questionnaire prepared for collecting the information and estimates the incidence of retained placenta in relation with age, parity and body weight and body condition of dairy cows. The data collected directly from owner of dairy farms and register books of government and private farms. Management of cows: In experimental, the individual cow owners were housed their cows were traditional housing and most of them feeding straw and green grass, few concentrate feeding and little feeding balanced diet; very few were deworming and vaccinating their cows and most of the farmer were not waiting more than twelve hours for placental come out, after one to two hours they called doctors for manually removed. But mini and large sized dairy farmer had improved practiced on rearing, feeding, deworming and vaccination. When the cows prior to calved most of our farmer fed their animals worm rice gruel and separated from others animal with paddy straw bedding were used. Grouping of Experimental Cows: To achieve the goal animals were group according to following considering factors: Breed- The cows was classified in Indigenous or Local (n = 470) and Crossbred (n = 735). Age- The age cows were determined from birth register and examined by teeth and cornual ring reading. After confirmation of age of these cows and then classified as follows- Group I: < 3 years (n=295), Group II: 3- <5 years (n=430), Group III: 5 - <7 years (n=291) and Group IV: > 7 years (n=189). Parity- The cows those gave 1st calf considered as parity 1 (P1), those gave 2nd calf consider as parity 2 (P2), 3rd calf as parity 3 (P3) and so on. Where, Poor = Marked emaciated. Fair = Ribs are usually visible, little fat covered dorsal spines are barely visible. Good = Animals are smooth and well covered but fat deposits are not marked. Statistical analysis: The data were compiled; SPSS program [11] to analyze the incidence and chi-square method used for interpretation of the findings. Retention of placenta (retained placenta, fetal membrane or afterbirth) was defined in this study as failure of spontaneous expulsion of the placenta within 12 hours after parturition.
