A) Winter Season (Dec. – Jan. & Feb.) It is the time of extremely cold temperate and moderately cold temperate in N.W. Region and eastern and southern region. Grazing condition deteriorates due to poor growth of grass. During this period take preventive measures as follows: i) Provide supplementary feeding to ewes and rams. ii) Mature animals are now to be prepared to face the coming mating season. iii) Protection against cold in temperate region. B) Spring Season (March & April) I) In Dry northern, Southern and Eastern Region:-

i)	Ewes are planned for mating.  Estrous in ewes range from 20-42 hours with an average of 30 hours.  Ovulation occurs about 24-30 hours after the onset of estrous.  If the ewe is not bred or if she fails to conceive, estrous recurs after an interval of about 17 days.
ii)	Just prior to breeding season shearing of the flocks make them more active and in many cases, will improve their fertility.  Sheep are shorn at the end of winter season when warm weather commences and sufficient grazing in the field is available.
iii)	Dipping at this time of the season is another essential provision for safeguarding sheep for the following reasons:

a) To remove excess of faulty materials and dung from the fleece prior to clipping. b) To cleanse the skin from the products of sweat, shed epithelial scales and other waste materials. c) To erradicate the common parasitic agents such as lice, ticks etc. d) To prevent attack by the sheep blowflies and consequent infestation with maggots.
