Philosophy: I believe that Animal Scientist should seek to better understand the form and function of animal systems and utilize this knowledge to develop and or improve approaches that will enhance the productivity and profitability of farming operations, in so doing, conserve and improve our animal genetic resources, reduce food insecurity, and improve the livelihood of the producer and the welfare of the world’s citizens.
Research Focus: Focused on increasing productivity of small ruminants by increasing reproductive performance, enhancing reproductive outcome and productivity in sheep, dairy cattle and water buffaloes. These efforts were supported entirely from grants/awards, in kind donations and partnerships with producers.
I also partnered with the Division of Natural Resources and Design and USDA Natural Resources Conservation Service (NRCS) to develop models for assessing Real Property Market Value for the Wetland and Grassland Reserve Programs.
Sheep Reproductive Performance: Research on enhancing sheep reproductive performance have been aimed at enhancing lifetime productivity of the ewe by reducing the age at first lambing; increasing the frequency of lambing through rebreeding early postpartum in both the breeding, and non-breeding season, increasing feasibility and reproductive outcome from synchronized breeding, and increasing total weight of lambs weaned. My studies was the basis for FDA approval of a progesterone delivery device (CIDRs) for use in breeding non-lactating ewes during the anestrous period. My graduate students and I followed up on these studies and investigated approaches to enhance reproductive outcome from out-of-season breeding in dry mature ewes, lactating ewes and nulliparous females. Similar studies were conducted in hair sheep in Trinidad.
Improving Reproductive Outcome and Productivity of Animals in Tropical Latitudes: Efforts in this area focused on the following:
Evaluation of Timed Artificial Insemination (TAI) Protocols in Dairy Cattle. Pregnancy rates in dairy cattle in the tropics can be less than 10% in part due to poor estrous detection rates (less than 25%) and the availability of a limited-centralized artificial insemination program. Therefore, appropriate TAI treatments can have a positive impact on productivity and profitability of dairy cattle operations under these conditions.
Evaluation of Timed Artificial Insemination (TAI) Protocols in Water Buffaloes:
Evaluation of Lactation Induction (LAI) Protocols in Dairy Cattle. Milk production of dairy cattle in tropical latitudes is often low and associated with poor reproductive performance reflected in extended age at first calving, long calving intervals with a high proportion of animals in extended lactation and a high proportion of open and dry (non-lactating animals). Lactation induction was evaluated as a possible option for rapidly increasing the proportion of lactating cows and in so doing increase milk production. This study formed the basis for the award of the M.Phil in Livestock Science to Mr. Reeza Ramgattie.
Relationship between circulating concentrations of Anti-mullerian Hormone (AMH), Age, Follicle Growth and Response to Superovulatory Treatments in Water Buffaloes.
Conservation, improvement and dissemination of water buffalo genetics are hampered by the low embryo yield following superovulation. AMH is known to be a reliable marker of the antral follicle population and superovulatory response in some species. Our studies characterized the circulating systemic concentrations of AMH and determines its relationship to follicle growth and development and superovulatory response in water buffaloes. These studied for the basis for the dissertation of Dr. Adam redhead
