If a few years ago we were facing the options of pig feeding systems trying to provide arguments to promote the change, today the change is already in the field.
When you arrive at a farm and the owner tells you that the best thing she could have done was to implement an automated feeding system in farrowing crates to provide appropriate nutrition to the needs of each sow, you feel pride and immense happiness.
Farmers are highly interested in utilizing tools that prioritize the well-being and health of their animals, as they witness the benefits of increased production and reduced issues.
This article provides an overview of various feeding systems tailored to specific production phases, highlighting their advantages and limitations.
FEEDING SYSTEMS FOR BREEDING SOWS
Feeding strategies during the initial 28 days of gestation
Following the insemination of sows, a critical period ensues, during which embryonic implantation takes place.
Approximately on days 12-14 post-fertilization, blastocysts undergo morphological changes and develop two filaments that enable attachment to the endometrial wall.
This stage holds immense significance for the embryo’s survival, as it ensures the provision of essential nutrients for its development.
The success of embryo implantation is negatively affected by stress, as it directly hampers the receptivity of the endometrium.
Factors like food competition and typical group hierarchy fights can pose risks during this phase. To address this, most producers house these sows in individual cages until the 28th day of gestation, ensuring proper nutrition and a calm environment for the mothers.
Feeding systems during this period are typically straightforward with minimal technological integration. However, it is essential not to neglect the needs of sows with lower body condition after giving birth.
This phase is crucial for recuperation and rest, and it is vital to provide them with suitable enrichment materials such as cotton ropes or straw. These materials contribute to their comfort and relaxation.
Feeding systems for group-housed pregnant sows
In this phase, our objective is to satisfy the sow’s maintenance requirements, avoiding excessive weight gain or loss.
It is important to remember that nutrition during this stage has a direct impact on the birth weight of piglets and milk production, particularly in the final third of gestation.
Incorporating systems that enable individual control of the feed ...
