Objectives:To produce 70 breeding rams of a specific breed every year to cover about 2500 breedable ewes for enhancing quantity and quality of meat and/or wool production
Capacity building in SAUs/ICAR institutes to produce above number of improved breeding rams.

RESEARCH ACHIEVEMENTS:
Highlights

Updation of flock status in home tract of Mandya sheep through systematic survey.
Distributed 393 elite breeding rams to 392 beneficiary farmers to cover their 14,000 breedable ewes for enhancing quality and quantity meat production.
Strengthened the conservation of Mandya Sheep in the form of in-situ conservation through the establishment of Elite Mandya sheep seed flock as nucleus breeding unit at LRIC(S), Nagamangala, KVAFSU, Karnataka.
Growth and reproductive performance of Farm flock and progenies of the distributed Elite breeding Rams is being carried out for assessing improvement of productive and reproductive traits in field flocks.

Saleable technology developed

Formulation of feed for different age group of sheep to improve the growth and production performance.
Formulation of feeding schedule for breeding rams, breeding ewes, pregnant ewes, lactating ewes, yearlings, hoggets (3-6 month), lambs (2-3 months) and young lambs (birth to 1 month).
Developed the feed trays for different age group of sheep to avoid the wastage of feed and fodder.
Status of Mandya sheep rearing in the home tract area has been documented.
Adoption of different breeding technologies to improve the reproductive efficiency of Mandya Sheep and streamline of different breeding strategies.
Oestrus synchronization and Artificial Insemination technology has been introduced in the field flock of Mandya sheep.
Studied the physical and morphological characteristic of Mandya Ram.
Generation of Growth performance of Mandya Sheep.
Generation of Average daily gain of Mandya Sheep.
Generation of Reproductive performance of Mandya Sheep.
Selection criteria at six month to bring about improvement in later ages.
Reduced the age at sexual maturity, age at first lambing and lambing interval through artificial breeding technologies.
Mortality pattern in different seasons and their control measures.
Newer breeding techniques.
Silage making and straw enrichment with locally available fodder.
Agro forestry as a means of conventional fodder.

Technology commercialized

Breeding plans for improved growth and reproductive performance.
