Spring is the peak season for hatching. In order to ensure the hatching rate and the quality of the chicks, eggs will be preserved. The first time the egg is laid is 5-6 days after hatching, the main inspection is the fertilization rate and embryonic development of the egg. Under normal light conditions, embryos that are normally developing can be observed to float upward, and the vascular network on the yolk sac expands into a spider web. The weakly embryonic blood vessels are slender and have a small expansion surface; no zygote, the egg is transparent, and the shadow of the egg yolk appears vaguely; the dead zygote shows blood lines or blood rings, and sometimes the black spots of the sticky shell are visible. The second time the eggs were hatched for 11 days. When the large stereoscopic hatchery used eggs for the second time, a lot of sampling methods were used to spot the embryos of several egg trays. In a normal developing embryo, the allantoic sac closes at the tip of the egg, enveloping the protein in the egg, and the tip of the egg is covered with blood vessels; the stunted embryo, the allantois have not been closed, there is no blood vessel distribution at the tip of the egg; Distribution, translucent inside the egg, there is a fuzzy mass in the egg. The third time the egg was laid on the eggs, 18 to 19 days after hatching. In a normal developing embryo, the air chamber is enlarged, the edge of the air chamber is curved and tilted, and the blood vessel is thick. Occasionally, the embryo flashes, that is, fetal movement, commonly known as turning and flashing hair. Embryos that are about to be hatched occupy embryonic eggs; embryos that are stunted have enlarged air chambers, are flush, blood vessels are visible, and the tip of the egg is bright; dead embryonic egg chambers have little or no curvature at the edge of the air chamber, and the tip of the egg is made Bright, dark inside the egg, muddy, touch without warmth. When a large-scale modern hatchery is hatched at a large scale, the fertilization rate of the egg is high, and the performance of the hatchery is better. Therefore, egg inspection is generally not required, which can save manpower and time. If the fertility rate is less than 85% at the time of spot check, eggs are still kept to ensure hatchability and chick quality.
PRODUCT INTRODUCTION:
With corn starch as raw material, through the enzyme, after liquefaction, concentration, drying and a series of processes and gained white powder products, can promote bifidobacterium of the body significantly and have the functions of water soluble dietary fiber, low calorific value, prevent dental caries etc., so it is a kind of functional oligosaccharides used widely.
