Key points and precautions of feed management in chicken farm in summer

Summer weather is hot and there is a lot of precipitation, which easily has a great impact on chicken farms, such as high temperature and high humidity.

Under this condition, chickens in chicken farms are prone to stress reaction, and their food intake will be significantly reduced, resulting in insufficient nutrient intake and affecting normal and healthy growth.

Therefore, it is an effective means to improve the production performance of chickens by implementing reasonable feed management methods in chicken farms in summer high temperature season.

Let's take a look at the key points and precautions of feed management in chicken farms in summer.

1, energy should be increased.

Chickens are prone to anorexia in summer. Appropriate amount of oil can be added to the daily feed to change the palatability of the feed. At the same time, oil can prolong the residence time in the digestive system and effectively promote the feed intake and digestion and absorption of chickens.

If the chickens in the chicken farm have heat stress reaction, you can add 2%-3% fat energy to the feed appropriately, and reduce the consumption of corn accordingly.

It should be noted that fat is easily oxidized and deteriorated, so antioxidants should be added to the diet at the same time as fat.

2, protein raw materials should not be too high.

In summer, ordinary farmers often make up for the lack of protein intake of laying hens by increasing the crude protein content in feed.

In fact, a big misunderstanding is that protein produces far more calories than carbohydrates and fats, thus increasing the heat burden of chickens. Therefore, protein raw materials should not be too high.

The correct way should be to reduce the consumption of raw materials with low utilization rate in protein, such as miscellaneous meal, appropriately reduce the consumption of animal protein feed, such as fish meal, and increase the raw materials with high protein content and high utilization rate, such as soybean meal, generally by increasing 10- 15% on the basis of the original diet, so that the added amount can reach 360mg of methionine and 720mg of lysine per chicken per day, and pay attention to maintaining amino acids.

3. Regulation of minerals and vitamins

Heat stress in summer easily affects the quality of eggshells of laying hens, and also affects the absorption of elements such as magnesium, manganese and calcium. Therefore, the proportion of these calcium elements in the summer diet formula should be adjusted according to the decrease of food intake.

In principle, the adjustment level of calcium should not exceed 4%, and the adjustment level of available phosphorus should not exceed 0.42%.

In addition, attention should also be paid to the supply granularity of calcium source, and it is best to use 2/3 granular phosphorus source.

Moreover, heat stress has a great influence on the absorption of vitamin E, vitamin C and B vitamins, and the amount added in summer should be adjusted to 2-3 times of the normal amount.

4. Add anti-stress drugs to relieve summer heat.

Qiangzhuang powder is a commonly used anti-stress drug for relieving summer heat. Appropriate addition of this product to feed can play a role in invigorating qi and blood, eliminating dampness and expelling toxin, and strengthening chicken physique. And it is beneficial to improve the egg laying rate, prolong the egg laying peak period, reduce the feed-egg ratio, increase the egg weight and improve the egg quality.

To sum up, chicken farms are prone to heat stress in summer, which easily leads to confusion in chicken feed management.

Therefore, according to the actual situation, we should adjust the feed balance, unify the standards of various elements, do a good job in relieving summer heat and humidity, and really do a good job in feed management of chicken farms in summer.
