Use of anions and catins in sows

摘要

It has been shown that balancing the diet for anions and cations plays an important role in preventing milk fever in dairy cows. Therefore, why not benefit from this knowledge and use it in sows too? Of course sows are not usually afflicted with milkfever, but delayed farrowings resulting in increased numbers of still births are a common problem in sow herds (see Table I). The causes include: Tedious labour (too weak muscle tones) as a result of too low blood calcium levels. Insufficient release ofoxytocin, the hormone which elicits labour pains, milk flow and milk let-down. Too narrow birth canals due to genetics, constipation and primi-parous sows. Parity number.
