A good diet is not enough to prevent post-weaning diarrhoea in the youngest, lightest animals, since they do not eat as much as they should.
The article suggests various environmental and feed program changes and assesses their effect on pig performance and feed cost.
The use of proven phytases in swine, is recognized to be an extremely useful tool for nutritionists not only in formulating more affordable feed without altering animal performance, but even improving it.
The difference in the conversion rate expected within a practical range of average particle sizes between 600 and 1000 microns can be of up to 2-4% between both ends.
The results show that digestibility of the same diets is indeed higher for gestating and lactating sows than it is for growing pigs.
Making use of the NET energy system for sows to formulate feeds makes it possible to achieve a smooth transition from gestation to lactation diets, which makes the transition period around farrowing easier for the sows.
The nutrient requirements of the sow change during gestation and the feed provision must meet this demand; hence the need for phase feeding.
