Key points to pay attention to when raising laying hens in spring
Spring is the beginning of a new year, and the quality of spring management directly determines whether the egg chicken farm is profitable. So spring feeding management is very important, and below we will introduce it from several aspects.
1、 Temperature
The temperature difference between day and night in spring varies greatly, and sometimes there may be a sudden drop in temperature due to late spring cold. Therefore, insulation measures should be taken, and insulation facilities should not be removed quickly just because the temperature rises. Timely response should be made according to temperature changes to ensure that the temperature of the egg and chicken coop is within a suitable range.
2、 Humidity
The humidity range for laying hens is 40% to 70%, and the suitable humidity is 50% to 65%, preferably not exceeding 70%. Low or high humidity can affect the stress of chicken flocks, and can exacerbate disease susceptibility. In spring, the relative humidity inside the house is high, and it is necessary to adjust the humidity on the basis of maintaining temperature in order to improve the egg production of laying hens.
3、 Feed
1. Raw material quality
Pay attention to the quality of corn and bran, especially the moisture content. In spring, the humidity in the air is high, and the temperature is suitable for the growth of fungi. At this time, it is important to pay attention to the hygiene indicators of corn and bran, especially mycotoxins. Mycotoxins are harmful to laying hens. Mycotoxins not only reduce the nutritional value of feed, but also reduce the immunity of laying hens. As a result, the incidence rate of laying hens increases, making it difficult for laying hens to breed. See the following figure for details.
For example, aflatoxin B1 mainly causes damage to the liver and can cause liver cell degeneration, necrosis, and acute liver damage. It can also lead to a decrease in hatching rate, decreased egg production, which takes several weeks to recover, smaller eggs, and reduced yolk weight. Causing immune suppression, inducing coccidiosis, marek's disease, salmonellosis, etc.
Detoxifiers, as an effective means of preventing the harm of fungal toxins, are widely used in animal husbandry production. As a professional provider of mycotoxin solutions, Zhengchang Feed Technology has been committed to the research and product development of feed mycotoxins. Jiemolin products are processed using patented production processes, with a high decomposition rate for mycotoxins, especially for aflatoxins, which can reach up to 100%. The decomposition rate of Jiemolin for different fungal toxins is as follows:
2. Reasonable ratio
It is necessary to strictly follow the recommended formula ingredients for the compound premixed feed of laying hens, and not change the formula arbitrarily, otherwise it will affect production performance. For example, there is a difference in the proportion of soybean meal added to the pre mixed feed for laying hens between 20 and 25. The 20 soybean meal is based on the high nutrition of the pre mixed feed, making up for the deficiency in the diet, while reducing the amount of soybean meal used and lowering feed costs. Therefore, the price of the 20 soybean meal pre mixed feed is higher, while the price of the 25 soybean meal pre mixed feed is lower.
If 20 soybean meal is mixed into 25 soybean meal, the nutritional content of the feed exceeds the needs of the laying hens, which will increase the burden on the laying hens, cause metabolic diseases, and reduce production performance. For example, the eggs will become larger, affecting the use time of the laying hens, and the maintenance time of the egg production peak period will be short, causing losses that outweigh the gains; In addition, the 25 soybean meal premix, combined with 20 soybean meal, results in insufficient nutrition in the feed, decreased weight and uniformity of the chicken flock, smaller or fluctuating egg size, shorter peak egg laying period, and lighter weight of laying hens, directly affecting the economic benefits of laying hens.
Each type of Zhengchang egg laying chicken premix uses high-quality feed ingredients, scientific ratios, and has been obtained through scientific experiments and verification by numerous breeding farms. The Zhengchang 20 soybean meal egg laying chicken premix not only does not affect production performance, but also reduces feed costs. As the saying goes, "the best plan for a year is in spring." Spring is the beginning of the year, and strengthening breeding management in spring lays a solid foundation for a bountiful harvest throughout the year.
