What nutrient concentration is appropriate for sow feed?
Nutrient concentration of sow feed?
Hello, teachers! I have been working on sow feed recently. But the nutrient concentration for sows is always inconsistent. I looked at the nutrient concentration for sow feed in our country's newly released 2005 standards and there are some differences from the NRC concentrations. Take the data for protein, calcium and phosphorus, for example. Our country's lactating sow feed is 14, CA is 0.8, available P is 0.32, but I saw at the Qingdao Sow Nutrition Conference that the protein in lactating sow feed should be at least 16, and available phosphorus should be 0.35. Teachers, could you introduce to me here the nutrient concentrations you use when making sow feed, and pass on a bit of your experience values? Thank you!
--------------------------------------
For high-lean-type lactating sow feed, protein is at 18%, and the lysine value is around 1.0%;
--------------------------------------
Look at how large the feed intake is. If the feeding amount can meet the nutritional needs of sows at different stages, then that is enough. If you are not sure, then go by the highest!
--------------------------------------
I heard that current sow feed is not very good, especially lactating sow feed. What exactly is the reason?
--------------------------------------
Maybe the nutrition cannot keep up!
--------------------------------------
The nutrient concentration for sows must be combined with feed intake. Formulas should be adjusted for the different seasons of winter and summer. In particular, the concentrations of multiple minerals and multiple vitamins for pregnant sows should be higher.
--------------------------------------
In the new national standards, the standards for finishing pigs are divided quite finely, and sows should actually be treated the same way. For breeds with relatively high lean meat percentage and relatively fast growth speed, it definitely will not work to follow the previous feed. The feed intake of this kind of sow itself is already very low. When the nutrient concentration of the feed is low, problems such as lactation and their own weight loss become even more prominent.
So I have always advised farmers not to raise excessively pure foreign-breed sows. When feed and feeding management cannot meet the requirements, their production performance is worse than that of ordinary breeds.
And for many hybrid-line sows, judging from their performance in Northeast China, they are all still quite good.
--------------------------------------
I would like to ask, are the nutritional requirements of French-line pigs a bit higher than those of D, L, and Y?
--------------------------------------
For sow feed, pig farms care most about the problems of constipation in summer and milk supply and leg problems during lactation.
--------------------------------------
Oh, thank you!!
