Moderator: Now, the price of this egg is going up for a while. It is only a bit of a child who buys eggs. But the heart of selling eggs mentions the eyes of the blind. Is there a way to reduce the risk of raising chickens? What is the lowest? One understands that the number of feeds for egg-laying chickens is relatively large, which accounts for 65-75% of the cost of breeding. Chickens eat nutritious soybean meal and corn, and the price goes high, which also causes aquaculture costs. The increase. Egg-to-egg ratio: Ratio of consumed feed to egg per unit of production. Under normal husbandry conditions, the production of 1 kg of eggs consumes 2.5 kg of feed material. The ratio of eggs to eggs is 2.5:1 if the chicken can eat less? No, eating less or not, not getting the eggs, it's not even worse. Reporter: Want to run the horse, do not want the horse to eat grass. This is where the best of both worlds can be found. However, today we introduce to everyone the small grain-type egg farm Nongda 3, eat less, save food. ) In comparison, there is still a difference. The chicken leg called Nongda 3 is only 7.5 cm long. The average chicken leg is 9-11 cm long. It is better than not knowing it, but it is 10 centimeters taller and shorter, and the body length is also longer. The difference is 3-4 cm. Because this leg is short, it is also called bantam. But can a small child save money? Ning Zhonghua: (Professor at China Agricultural University) This is where there is a lot of scientific stuff. This kind of chicken has introduced a dwarf gene called DW gene. After introducing this gene, the chicken's body shape will naturally become smaller than ordinary chicken. About 30% smaller, but this does not affect the utilization of feed, it eats less, but its utilization of feed is high. With this DW gene, it can improve the efficiency of feed conversion, another you see this chicken, Its activity is very small and relatively honest, so it can also save some energy. After 10 years of cultivation, researchers at the China Agricultural University extracted dwarf genes and introduced this dwarf gene into high-producing layer chickens. The grain can produce eggs with high yield. The hen used as a parent of a dwarf chicken and a common brown hen as a female parent is the Nongda 3 small hen. Ning Zhonghua (professor at China Agricultural University): What is said, the high feed utilization rate is because the dwarf chicken has more glandular stomach nipples than the average chicken, that is, developed digestive organs, so it is well absorbed and saves feed. This savings is not a single point, can save 20% -30%, under normal production conditions, dwarf egg layer than ordinary chicken as long as the income of 7,8 yuan it, especially in feed prices rise, egg prices are not high This advantage will be more apparent. Reporter: (I don't think, however, that the eggs produced by small chickens in this section of the diet are smaller than those I bought from the market. Wouldn't it be appropriate to calculate it?) Ning Zhonghua (Professor, China Agricultural University) Although this chicken has a relatively small number of eggs, its province has a particularly large number of feeds. In general, one egg production period saves 10 kg of feed compared to ordinary chickens. Small eggs only affect 1.5 kg of eggs, which is 1.5 times less than ordinary chickens. For kilograms of eggs, it is more cost-effective than 10 kg of feed and 1.5 kg of eggs. Different regions have different consumption habits for eggs. The South likes to buy small eggs. The bigger the better the North. However, the performance of this small chicken is very good, with few broken eggs, soft shell eggs and misshapen eggs. In addition, the small eggs have a high dry matter content, a stronger flavor and a better taste. Feeding small-scale hens of saving diets is almost the same as feeding ordinary hens. Updating them can reduce costs. Reporter: The body is small, and the area occupied is small. The original raising layer chickens were raised with three layers of cages. This can lower the height of the cage and turn it into a four-layer cage. The total height remains unchanged. We also want to be more profitable. In addition to saving feed, if we can produce green eggs, the selling price will certainly be higher. As farmer chickens are free to eat, the eggs they produce are already recognized by consumers and the price is high. However, the egg production of the chickens is relatively low, and the high-yielding, small-scale layer chickens are free-ranged and can also produce green eggs. The price is more than twice as high as the eggs laid by laying hens. The Nongda 3 uses Orchard. The way of raising can be achieved. So, this will not cause harm to the orchard? Ning Zhonghua (Professor of China Agricultural University): No, you see this chicken is quite honest. Its short legs will not fly to the tree, so it has no effect on the fruit on the tree. The chicken eats the bugs on the fallen fruit trees in the tree, which is conducive to ecological farming in the orchards. The insects will not invade the fruit trees. The fruit trees can fight less or even fight drugs, so that the fruits can be green and pollution-free. Chicken droppings were thrown into the ground by chickens to increase soil fertility. Fertilized so it forms a complementary interest. You would say: Isn't it common for ordinary layer chickens to be free-range in the orchard? Put chickens in the orchard, but also to select suitable stocking breeds, it is not appropriate to run wildly in layers. Nongda 3, a small egg breeder, has small legs and can't fly. Even if it is on a tree, it can only stand on a small scale. On the branch, the tree will not eat fruit, and its temperate, easy management, is very suitable for free-range orchards in the orchard. There are also large eggs under ordinary laying hens. In the case of free-range chickens, they are easily damaged and affect the efficiency. This also shows the advantages of producing small eggs. Although the food is abundant in free range, it is necessary to supplement the whole price of feed and clean drinking water. The chicken shed is built in the corner of the orchard and faces the south. It can shelter the wind and shelter the chicken from the rain. This is a simple home for chickens. The laying hens have the characteristics of light ovulation. In order to promote egg production, the lights are turned on every day to fill the light. It is very important to pick eggs in time because the eggs will be contaminated in the coops or trampled, and it is better to pick them once every hour. Ning Zhonghua (Professor at China Agricultural University): The quality of eggs is not only high but also guaranteed. Caged chicken raises a large number of chickens in a confined space, leaving no room for chickens. The physical and mental health of the caged chickens was seriously hurt. In Europe and some other countries, it has been advocated that animal husbandry is called free-living. Our country must also promote animal welfare.
