  The objectives of this cross-sectional study were to determine the underlying disorders and effective treatment of postpartum anoestrus. Rectal examination accompanied by ultrasonography was performed twice in a 10-day interval on crossbred (HolsteinxZebu) anoestrus cows at = 60 days postpartum to diagnose their cyclic status. Cows diagnosed as silent estrus and true anoestrus were allotted to different treatment and Artificial Insemination (AI) protocols. The pregnancy was diagnosed thereafter by ultrasonography between 30-35 days post AI. The prevalence of anoestrus was 18.5% (83 out of 448 cows) as reported by the farmers with silent estrus 53.0% (n = 44), true anoestrus 42.2% (n = 35), cystic ovarian disease 2.4% (n = 2) and uterine infections 2.4% (n = 2) as the underlying disorders. Treatment of silent estrus was revealed estrus and conception; respectively, in 52 and 43% cows carefully monitored of estrus signs for AI (Group I, n = 23) and in 73 and 45% prostaglandin treated cows with AI on observed estrus (Group II, n = 11). Prostaglandin treatment followed by timed AI with GnRH administration at first AI (Group III, n = 10) revealed 60% conception. The difference in rates of conception was not significant among different treatment groups (p>0.05). Treatment of true anoestrus was revealed estrus and conception; respectively, in 82 and 64% nutritionally supplemented cows (Group IV, n = 11) and in 50 and 40% suckling restricted cows (Group V, n = 10). GnRH treatment followed by PGF2α administration and timed AI with GnRH at first AI (Group VI, n = 9) revealed 44% conception. Control anoestrus cows (Group VII, n = 5) without any treatment did not show estrus. The difference in rates of conception was significant (p<0.05) between the groups. In conclusions, close monitoring of silent estrous cows for estrus and nutritional supplementation for true anoestrus could be effective tools for successful reproduction.

  Most of the researches done in the fields of skin detection has been trained and tested on human images of African, Mongolian and Anglo-Saxon ethnic origins for face recognition, human motion detection, pornographic and nude image prediction, etc. Although, there are several intensity invariant approaches to skin detection, the skin color of Indian sub-continentals have not been focused separately. The approach of this research is to make a comparative study between three image segmentation approaches using Indian sub-continental human images, to optimize the detection criteria and to find some efficient parameters to detect the skin area from these images. The experiments observed that HSV color model based approach to Indian sub-continental skin detection is more suitable with considerable success rate of 91.1% true positives and 88.1% true negatives.

  Cattle among other livestock species available are the most versatile component in relation to existing integrated agricultural farming system in Bangladesh. About 90% of total 24.5 million cattle are of non-descript indigenous in origin along with 10% crossbred constitute national herd. Among indigenous cattle (Zebu) in different region non-descript Deshi, Pabna, Red Chittagong and North Bengal Grey are predominant. The reproductive performance of these cattle and other crossbred are poor. Indigenous Pabna cattle attain puberty relatively earlier than other types. It is found that about two services are required for conception. Average calving interval ranged from 365-536 days and average postpartum service period is ranged from 103-161 days among the indigenous and crossbred cattle. Anestrus and repeated conception failure are major causes of the reproductive inefficiencies. Higher prevalence of Brucellosis is reported although its impact in cattle reproduction and human health yet to determine.
