Advantages:  High Prolificacy: 6-12 no./litter  FCR – 1 : 2.5 – 3  Short generation interval – 2 farrowings / year  More quantity of meat/unit weight  More energy / unit weight  High meat : Bone ratio  Easily adapted to integrated or mixed farming system.  Successfully maintained on discarded feed, garden waste and kitchen waste.  High dressing percentage  High growth rate: 10 Kg./month  Early maturity: 9-10 month of age  Early puberty: 5-8 months  Length of oestrus cycle: 21 days  Oestrus period: 2-4 days  Service: 2nd /3rd day of oestrus  Rebreeding after parturition: 3-4 weeks after weaning.  The carcass yield is high: 65 -80% of live weight. (Pigs are known for their meat yield, which in terms of dressing percentage ranges from 65 - 80 in comparison to other livestock species whose dressing yields may not exceed 65%.)  Suckling Period: 56 Days  Pigs thrive well in temperature range of 20-25oC.
