The chicks mentioned here are chicks within 42 days of age. This period chicken management must be scientific. Through the practice of raising chickens in the spring of recent years, the author believes that the farmers must pay attention to the following eight aspects, that is, “eight attentionsâ€. First, pay attention to drinking water. First-time chicks first drink first-time drinking water, early drinking water is best to use 18 °C sugar water or warm water, early drinking should be carried out before the first feeding; drinking water to prevent chickens just hatched after the weak or lack of water, promote Digestion and absorption of yolk in vivo; conditional, every 50 chicks are equipped with a 4.5 liter automatic drinking water dispenser, the drinking fountain should be often sterilized, the water should be hygienic, and 80 million units of gentamycin can be added to every 0.5 kg of water. Allowing chickens to bake can prevent diseases. The second is to pay attention to temperature. Temperature is the key to brooding. Newly hatched chicks generally require an ambient temperature of 32-35°C, and then drop 2°C per week. Whether the temperature is appropriate or not, in addition to measuring through the thermometer, the chick's spirit and activity performance should be observed. If the chicks are piled in the center of the heat source, The occurrence of "squeaking", unrest, slowness of movement, and uneasy feathers indicate that the temperature is too low. If you stay away from heat, breathe openly and drink plenty of water, indicating that the temperature is too high; if the chicken is well-distributed, lively, quiet, and comfortable to sleep , indicating that the temperature is moderate. The third is to pay attention to feeding. After hatching, the first feeding of the chicks is called opening; it is generally good to eat 12-24 hours after hatching. Within 12 hours after hatching, there are 5 grams of egg yolk in the chicken body to have enough energy; use corn flour, small pieces. The rice is mixed with wet or dry materials to eat; for the first few days, the principle of “less feeding and adding 80% full†is used, and the feed is sprinkled on the dark plastic sheet and gradually changed to a food tank; Add 1% gravel to the feed to aid digestion and add a certain proportion of green feed to the feed. The fourth is to pay attention to humidity. At the beginning of brooding, the humidity should be greater, which is conducive to the absorption of abdominal yolk to prevent the body from dissipating water; the humidity before 10 days of age is generally 60-65%, 50-60% after 10 days of age; under the conditions of high temperature and high humidity, Microorganisms are prone to growth and reproduction. Chick evaporating and heat dissipation are hindered, resulting in high body temperature. This makes the disease of chickens particularly susceptible to coccidiosis. Therefore, attention should be paid to ventilation and ventilation, ground watering and ground-breaking. The fifth is to pay attention to the light. With the increase of the chick's age, the daily light time should be maintained at a certain or slightly reduced, can not increase; 1-3 days due to poor visual acuity, in order to ensure the intake of food and drinking, 22-23 hours a day light, after each week gradually The reduction of 20 minutes until 9 hours of light every day, until 20 weeks of age; to make the indoor lighting evenly, the lights should be hung in the water above the trough and the trough, the appropriate light intensity brooding can be calculated according to 30 watts / 10m2. Sixth, pay attention to ventilation. Ventilation and ventilation can ensure fresh air in the brooding room. Bacteria, viruses and dust in the house can be discharged through ventilation. Natural ventilation is generally adopted. The temperature difference between inside and outside is used to open some doors and windows to allow indoor and outdoor air exchange. Seven is to pay attention to grouping. Group chickens according to their size and strength and adjust them every half month. If the chicken density is too high, chicks will grow slowly and prone to paralysis. Eight is to pay attention to disease prevention. "Preventing stress is an effective measure for farmers to raise good chickens; vaccination is an important means to prevent the occurrence of chicken diseases; common chicken immunization procedures are: 1 day old injection of Marek's vaccine; 10 days old chicken bursa vaccine Drinking water; 15 days of age with chicken II lineage drops or eye drops or drinking water; 21 days old chicken pox thorn seed; 35 days old chicken bursa vaccine drinking; 40 days old chicken II line seedlings and infectious bronchus Yan H120 mixed drinking water.
Food
additives are substances added to food to preserve flavor or enhance its taste
and appearance. Some additives have been used for centuries. With the advent of
processed foods in the second half of the twentieth century, many more
additives have been introduced, of both natural and artificial origin.
Sweetener is a food additive that gives sweet drinks a sweet taste. Sweeteners
by nutritional value can be divided into two kinds of nutritional
sweeteners and non-nutritious sweetener; according to their sweetness r
bit is divided into low sweetness sweetener and high sweetness sweet
taste; according to its Sources can be divided into natural sweeteners and synthetic sweeteners.The natural sweeteners including stevia sweetner,natural sweetners.
main effect
The main role of sweeteners in food is as follows:
(1)
taste: sweetness is one of many food indicators, in order to make food,
drink with a palatable feeling, need to add a certain amount of
sweetener.
(2) the flavor of the regulation and
enhancement, in the pastry generally need sweet; in the beverage, the
flavor adjustment there is "sugar and acid ratio" one. The sweetener gives the product a good flavor and retains fresh flavors.
(3)
the formation of flavor, sweet and the flavor of many food is
complementary, the taste of many products is derived from the
combination of flavor substances and sweeteners, so many foods are added
sweeteners.
