Health foods contain a certain amount of functional health ingredients, which can regulate the functions of the human body, have specific effects, and are suitable for specific groups of people. General food does not have specific functions, and there is no specific range of people to eat. Health food cannot be directly used to treat diseases. It is a human body mechanism regulator and nutritional supplement.

Broiler Chicken Breeding Management
Achieve better egg production and egg quality (ie fertilization rate, hatching rate), in addition to nutrition to meet the breeder, there should also be supporting scientific management. Management of breeder chickens mainly starts with lighting, temperature of the house, quiet environment and whether the air is fresh. Supplemental light can not only extend the feeding time of the hens, but also can pass through the hen's optic nerve and promote the secretion of hormones needed for egg production in the anterior pituitary. Therefore, the number of laying times of the hens is closely related to the light. Egg-laying hens can only increase the light time during the laying period, and must not be shortened. When they increase, they should gradually increase, and the amplitude should not be too large. Silky chickens should be increased to 15-16H per day during the laying period. The light intensity requirements of 15 square meters 40 watts is good, the light intensity should not be reduced, the light color is not changed from white to shade. There are three ways to add light: A, plus artificial light in the morning. B. Add artificial light at night. C. Add artificial photos each morning and evening. It is generally better to use C light to add artificial light immediately and lately because it is consistent with people’s working hours and avoids turning lights on too early and late to affect rest. For example, in order to reach 16 hours of light, lights can be turned on at 5 a.m. and turned off at 10 a.m. The suitable temperature for black-bone laying is 13-25°C. When the average daily temperature is above 30°C and below 10°C, the egg production rate will be significantly reduced. Therefore, providing a suitable temperature is another important condition for ensuring a higher hen production rate. In addition, the chicken bones are scared and scared. Any agitation will affect the feeding, drinking, and mating of the flock until the activity will not only affect the laying rate of the hens, but also the light shell egg rate will increase accordingly. Therefore, the breeding house should be Keep the environment quiet and prevent adverse reactions in the flock. To sum up the above points, the season of management of breeding chickens can be summarized as follows: Spring management. The spring climate is mild, and various microbes are easy to breed. Various viruses and pathogens are prone to long-term survival in and outside the homes. It is a season of easy onset, and strict prevention and disinfection should be done. Before the weather turns warm, a thorough disinfection should be conducted to reduce the chance of the disease. The spring is also a good season for egg production and reproduction. Should seize the opportunity, carefully feeding and management, for more eggs, more than hatching chickens. At the same time, in the early spring season, due to the fact that the weather is still cold, attention should be paid to keeping the breeders warm. The ground of the chicken house should be kept dry, bedding changed frequently, pay attention to ventilation, and keep the air in the house fresh. 2. Summer management. Summer is hot and there is more rainfall. The poor appetite of the chickens and the reduced feed intake are the main reason for the prevention of heatstroke. The shed must be ventilated to open doors and windows. When the temperature is higher than 30°C, feather water spray and drinking soda water should be used to reduce the temperature of the chicken body. The stadium roof should be covered with straw, but also can plant some luxuriant plants. When feeding, feed more and sooner or later, feed less at midday, and supply some green fodder at noon. 3. Autumn management. In the autumn in the south, the temperature in the early period was still high, and it was not until before the Mid-Autumn Festival that the heat was reduced, but the light was getting shorter. After a short production season, the flock began moulting and stopped production. During periods of high egg production, rich nutritious feed is needed to promote longer-term egg production. For those with early molting, fewer eggs and weak hens should be eliminated in time. The moulting stage should provide enough protein, especially methionine and cystine. Inoculation and deworming can be carried out during the season and the impact on laying eggs can be minimized. 4. Winter management. In winter, the temperature is low and the light is short, and the chicken production is greatly affected. The central task of winter management is cold insulation. If you use fine sand as litter, you should use warm materials such as chaff, sawdust, or chopped straw instead. To prevent icing in the sink, warm water should be available if conditions permit. Put the chicken late in the morning and close the chicken early in the evening. When you put your chicken in the morning, you should first open the window so that when the temperature inside or outside the house is not too large, you can open the door and put the chicken. The density of flock in winter can be increased appropriately, but ventilation and air exchange should be taken care of to remove harmful gases in the house. The energy feed in the diet should not be too high to prevent the birds from becoming over-fat and affect egg production.
