What are the tips for sow feeding and management?
(Agricultural Wealth Network) (1) Make sows give birth during the day
From 9 to 11 am 1 to 2 days before the sow is due to farrow, inject 1 to 2 milliliters of cloprostenol injection into the sow's neck muscle; this can make 98.2% of sows farrow during the daytime the next day, with an effective rate as high as 100% and a piglet survival rate of over 98%.
(2) Make sows farrow in spring and autumn
Arranging sow farrowing in spring and autumn can increase the piglet survival rate and achieve 5 litters in 2 years. The first litter can be arranged for mating in November to December, with farrowing in March to April of the following year; the second litter can be arranged for mating in May to June, with farrowing in September to October.
(3) Increase the sow farrowing rate
From 3 days after weaning to the estrus period, feed each sow 400 milligrams each of compound vitamin B and carotene and 200 milligrams of vitamin E daily; after mating, halve the dose and continue feeding for 3 weeks, which can produce 2 to 3 more piglets per litter.
(4) Early pregnancy diagnosis in sows
At 3 to 4 weeks after mating, press with the thumb and index finger on the back between the 9th thoracic vertebra and the 2nd lumbar vertebra; if the spine arches slightly, it indicates pregnancy, while if the spine is concave, it indicates not pregnant.
(5) Calculation of the sow's expected farrowing date
Add 3 months, then 3 weeks and 3 days to the mating date, and this is the expected farrowing date. For example, if the sow's mating date is April 20, the expected farrowing date is: 4+3=7 (month), 20+21 (3 weeks)+3 (days)=44 days, which is August 13.
