When it comes to feeding sows, every detail counts
One of the key factors in maximizing the potential reproductive capacity of a sow – and her lifetime performance – is maintaining appropriate levels of body fat and protein, also known as body condition.
Trouw Nutrition/Shur-Gain has developed feeding programs and tools for sows in gestation and lactation, which make up our MISSION sow program. The purpose of the program is to ensure that dry sows are fed correctly to achieve an optimal condition at farrowing.
Sows that are too lean or too fat will show reproductive failure, including reduced fertility or small litters, increased farrowing difficulties or more stillborn piglets, reduced milk yield or lower weaning weights, and increased wean-to-breed interval. It is imperative to maintain appropriate levels of fat and/or body condition for sows in gestation and lactation in order to have success.
The MISSION program accounts for all of these important details.
A customized feeding program for your farm
The MISSION feeding program enables customized feeding of pregnant sows according to their individual energy needs based on live weight (parity), fat depth, genotype, productivity of the sows, room temperature, and whether the sows are housed in groups or as individuals.
The MISSION gestation feeding program can be specific but adapted to the context of your farm.
Three phase program
The gestation program is divided into three phases.
The first third of the program allows the sows to recover their body condition.
The second third is a maintenance period in which piglets and mammary glands develop. Its important to not overfeed sows during this period so as to not compromise milk production, among other things.
During the last third, during late pregnancy, it is important to support the significant weight gain of piglets and the mammary gland.
It’s crucial to feed appropriate levels during gestation to restore and maintain appropriate target levels of body fat, and then encourage the sow to eat according to her appetite during lactation. This approach to sow feeding will lead to maximum milk yield and minimize sows’ fat and protein losses, and is a more sustainable method of maintaining reproductive efficiency than attempting to manage large body weight and fat variations between gestation and lactation.
