After the prohibition of antibiotics growth promoter (AGP), the biggest challenge farms facing is the increase of piglet diarrhea, which brings problems such as decline in production performance. The root cause of these problems is the sudden lose of functions of AGP: bacteriostasis and sterilization, adjustment of bacterial balance, improve feed efficiency, resulting in damage to the intestinal structure, imbalance of the intestinal flora, and decreased digestion and absorption of nutrients. Therefore, more attention must be paid to intestinal health after AGP disabled!
The key for intestinal health is to ensure intestinal cell nutrition and microbial nutrition to protect the intestinal cell structure and the intestinal micro-flora balance. However, the structural integrity of intestinal cells and the balance of the flora are closely related to protein nutrition. Therefore, it is necessary to select protein sources with high nutritional value, high health-care value, high commercial value while low risk to promote the intestinal health of piglets, alleviate the risk of diarrhea, and improve production performance.
How to judge whether the protein material has the characteristics of the "three-high and one-low"?Let’s look at our analysis on the truth of protein raw materials.
High nutritional value
Evaluation indicators Total deposited protein: crude protein * apparent ileal digestibility (AID) * deposition rate
Significance behind Higher value of total deposited protein will benefit more to the growth and development of the functional organs, such as the intestine and liver, increase muscle deposition, and increase the growth speed.
Method of determination
High health-care value
a. Low anti-nutritional contents
Evaluation indexes Plant protein (anti-nutritional factors), animal protein (protein spoilage products, oxidative rancidity products)
Significance behind Lower the anti-nutrient content will bring less damage to the intestines of piglets, and the better digestion and absorption capacity.
Method of determination
a. High functional ingredients
Evaluation index Functional ingredients in protein materials
Significance behind The higher content of functional ingredients will promote intestinal development, reduce intestinal permeability, promote repair after intestinal injury, and maintain intestinal health
Method of determination
Low risk
Evaluation content Biological safety and stability (quality, supply, price)
Significance behind Biosecurity under ASF situation directly determines the success of farming, and the instability of raw materials directly leads to instability of feeds.
Method of determination
High commercial value
Evaluation index Production performance of piglets, grower and finisher, sow
Significance behind Choose high-quality functional protein materials to improve product competitiveness for feed companies, reduce diarrhea, stabilize product quality, and gain more customers; improve performance for farms and obtain more economic benefits. Under AGP-free, a good piglet feed can drive the grower and finisher pig and sows to play a better commercial value.
Method of determination
In summary
When selecting protein raw materials for piglets under the background of AGP-free, you can’t just look at the protein content. You need to refer to the selection criteria of protein raw materials (high nutritional value, high health-care value, high commercial value, low risk), comprehensive evaluation from many aspects, and for the same characteristics require comprehensive analysis of multiple indicators to make accurate judgments. Reasonable selection and application of protein materials can effectively protect the intestinal structure of piglets from damage, maintain the balance of intestinal flora, thereby achieving intestinal health, alleviating the risk of diarrhea, and improving production performance.
