## Departments

CSWRI is departmentalised into six divisions, each attending to a specific set of activities.

### Division of Animal Genetics and Breeding

Division of Animal Genetics and Breeding was started in 1966 under the name Sheep Genetic Section with a mandate to conduct research on improvement of indigenous breeds of sheep for wool and meat. It was renamed as Division of Animal Genetics and Breeding in 1975. Animal Genetics and Breeding Division carried out pioneer work in the field of crossbreeding for improving the production of mutton, carpet wool, apparel wool and pelt. Various crosses like Avikalin, Bharat Merino, Avimaans, Indian Karakul, Awassi X Malpura and Avivastra were developed at this division. Research was also carried out with indigenous goats (Marwari, Sirohi and Kutchi) to evolve milk and meat producing goats. The biochemical polymorphic studies were undertaken to study the inheritance of various blood constituents and to determine the possible association of these biochemical parameters with economic traits. Cytogenetic studies were initiated in 1982. In 1997, Garole, a prolific microsheep of West Bengal was introduced for increasing prolificacy of Malpura sheep. Marker Assisted Selection (MAS) for prolificacy has been practically used in the routine breeding programme. In 2008, Patanwadi inheritance was introduced into prolificacy project to improve the milk yield and mothering ability. Three breed prolific cross was produced in 2009 and strengthening of prolific flock is in progress. Recently study on understanding the genetic basis of immune response variability in sheep has been initiated. Stalwarts like Dr. M V Krishna Rao, Dr. O N Singh, Dr. R M Acharya, Dr. R Nagercenkar, Dr. A L Chaudhary, Dr. R N Singh, Dr. C L Arora, Dr. S D J Bohra, Dr. B U Khan, Dr. V K Singh and Dr. A L Arora had shaped the development and progress of this division.

Network Project on Sheep Improvement (NWPSI) was initiated on to undertake survey, evaluation and improvement of indigenous sheep breeds under native environment. Different breeds of sheep are being improved through selection and inter-se mating for wool and mutton production. The mandate of NWPSI is genetic evaluation and improvement of indigenous sheep by selection. Presently, there are six ongoing centres of NWPSI including four farm based units and two field based units located at difference parts of the country. Coordination Cell: Project Coordinator Cell, NWPSI, ICAR-CSWRI, Avikanagar
Cooperating Units:
A. Farm based Cooperating units
1.ARC (CSWRI), Bikaner - Marwari sheep for Carpet Wool
2.CIRG, Makhdoom - Muzaffarnagri sheep for Dual purpose
3.MPKV, Rahuri - Deccani sheep for Dual purpose
4.SVVU, Palamner - Nellore sheep for Mutton
B. Field based Cooperating units
1.TANUVAS, Kattupakkam - Madras Red sheep for Mutton
2.ARC (CSWRI), Bikaner- Magra Sheep for Carpet wool
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.
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.
