The project has its headquarters at the Central Sheep and Wool Research Institute located in Avikanagar, Rajasthan. The project was started in 1991 and has centres located across India. Units and activitiesFarm based Cooperating units
ActivitiesThe activities include survey, evaluation and improvement of indigenous sheep breeds (Indian) under native environments.[6] Different breeds of sheep are improved through selection and inter-se mating for wool and mutton production. The mandate of the NWPSI is genetic evaluation and improvement of indigenous sheep by selection. [7] The objectives of NWPSI is Genetic improvement of indigenous sheep breeds by selection. The technical programme aims at improvement of indigenous sheep breeds under farm conditions wherein the male lambs are first ranked using selection index. Index incorporates body weight and wool yield at six months of age. Each field-based unit has four centres including a ram-rearing centre, covering a sheep population of about 1500 sheep per centre. The superior male lambs are selected from the farmers’ flocks on the basis of GFY1 and 6-month body weigh in Magra sheep and on six-month body weight basis in Madras Red sheep. Male lambs are initially identified at 3 month of age and are finally selected after first shearing. Selected male lambs from improver flocks are supplied for breeding to base flocks.[8] Breeding rams of high breeding value are produced from farm based unit every year for germplasm distribution. During the XI plan period about 900 improved breeding rams/ram lambs from five Farm Based Units were sold to different farmers/ State Govt/ NGOs for breed improvement programme and about 700 breeding rams / ram lambs were distributed in three Field Based Units for improvement of farmers flock. The Sheep Improvement Programmes will continue and efforts will be made to bring overall improvement in sheep productivity through distribution of superior germplasm and adoption of improved scientific management practices.
