Please note that some trial reports have been translated in their entirety, while for others only the abstract has been translated. Either way, a PDF version of the text will be available for download.
The addition of Hy-D to sow feed increased the number of pigs weaned and litter weight at weaning. It also doubled the vitamin D¬3 content in the blood of the sows in the trial.
Replacing inorganic with organically bound micro minerals showed no biological effects in sows when their need for micro minerals is covered via their feed.
The addition of more than 80 mg iron per feed unit to lactation feed does not affect the haemoglobin level in sows.
The current standards for protein and amino acids for gestating sows fully cover the animals' requirements when the sows are moved to the farrowing facility 5 days before expected farrowing.
The phosphorus requirement of sows is met when they are fed lactation feed with 7.5 g Ca and 2.6 g dig. P/FUsow and gestation feed with 6.4 g Ca and 2.0 g dig. P/FUsow. The amount of P discharged with these diets will be eliminated by the plants.
The production results were the same when phase-feeding lactating sows with two diets as when using only one diet.
Gastric health in sows improved when fibre content increased in gestation diets as well as lactation diets. Increasing the texture of gestation feed by adding rolled oats had no effect on gastric health.
Backfat of LY gilts increases when protein drops and energy supply increases in the weight interval 100-140 kg. A backfat thickness of 12-18 mm at service does not affect production results or longevity of the gilts.
The large piglets in a litter can be moved from the sow 6 hrs post-partum without adversely affecting their survival. Moving the largest piglets from a litter did not improve survival rates of the smallest piglets.
