An investigation was taken up to study the relationship of preovulatory follicle size at the time of first postpartum AI and CL biometry with conception using transrectal ultrasonography in 70 parous Graded Murrah buffaloes maintained under rural conditions. POF sizes were measured ultrasonographically and grouped in to small preovulatory follicle (SPF), medium preovulatory follicle (MPF) and large preovulatory follicle (LPF). Serum progesterone concentration at the time of AI and pregnancy status was negatively correlated indicating that when progesterone level declined to < 0.3 ng/ml (basal level) at the time of AI, the chances of the animal becoming pregnant was increased. The size of the POF was positively correlated to the size of the CL on day 10 in pregnant buffaloes. The overall POF diameter at the time of estrum was 12.31 ± 0.29 mm (Range 9 to 16 mm) in Graded Murrah buffaloes and 50 % of the buffaloes had POF size > 12 -14 mm. They conceived only if the POF diameter was more than 9 mm at the time of AI however there was no significant correlation between the POF size at the time of AI and conception. Thus, it was concluded that physiological maturity rather than the diameter of the follicle influenced the fertility in Graded Murrah buffaloes under field conditions.

Background: Long bone fracture in small animals has become a problem of concern in urban areas as well as rural areas because of road accidents. Canine long bone fracture cases presented at surgery wards of the hospital during 2017-20 were analysed for determining their incidence, occurrence and classification of fractures. Methods: The present study was conducted on long bone fractures in dogs presented to the surgery ward of SVVU Super Speciality Veterinary Hospital, Visakhapatnam from 2017 to 2020. Detailed history and signalment was followed by detailed physical examination to determine the site of fracture, extent of soft tissue swelling and presence of open wounds. Radiographic evaluation was done to localize the seat of fracture, to identify the type of fracture and to find out relation between the fracture fragments Result: Of all the cases of dog patients presented to the surgery ward 2.02% were diagnosed to have fracture of different bones. Fracture of long bones (326), comprised 1.50% of total cases and 74.42% of fractures cases. The highest incidence was recorded in mongrel dogs and the most common affected bone was tibia fibula. Fall from height was reported as an etiological factor in majority of the cases and Juvenile group of animals was found more affected.

Background: The dairy and livestock sector plays a very important role in national economy of India by contributing close to one third of gross income of rural households and nearly half of gross income in case of those without land. Subestrus is the most prevalent, frustrating and challenging problem encountered in postpartum buffaloes. Postpartum subestrus is one of the most prevalent, frustrating and challenging reproductive problem encountered in rural resulting into prolonged inter-calving period, reduced milk production and thus greatly affecting the economy of our farming community. Methods: The present study was carried out on Graded Murrah buffaloes during the period from September 2017 to August 2019 (includes breeding and low breeding season) which were maintained at farm and field. Treatment of sub-estrus lactating graded Murrah buffaloes (Bubalus bubalis) using Double PGF2 α (DPG) and Presynch-Ovsynch (POVS) their influence on fertility in farm and field condition during breeding and low breeding season was studied. Total cholesterol and progesterone concentration was recorded during different days/period of protocols. Further, overall per cent conception and pregnancy rates were recorded and compared between two protocols. Result: Progesterone levels increased significantly on day 21 post AI in pregnant buffaloes, whereas decreased significantly in non-pregnant buffaloes both in farm and field during breeding and low breeding season. The overall per cent conception and pregnancy rates were higher in POVS group than DPG group at both farm and field as well as during breeding and low breeding seasons.

The present investigation was conducted to study the
