Adding the right amount of green tea powder to fattening pigs can increase the nucleic acid content of pork by 20%, the cholesterol content by 10%, and the taste is more delicious. Feeding pigs at the end of tea can also increase the disease resistance of pigs and shorten the fattening time (from weaning to fattening for about 100 days). The cost is low and there are no side effects. It is a new technology worth promoting.
First, the feed formula.
When the weaned pigs are more than 15 kg, the best benefits can be achieved by feeding the ingredients in the early, middle and late stages.
1 40 days in the early period, pig weight 15 kg ~ 30 kg. Feed formula: 20 kg of corn, 15 kg of bran, 15 kg of dried hawthorn (dried sweet potato), 8 kg of rapeseed cake, 1 kg of fish meal, 200 g of salt, 40 kg of rice bran, 20 g of copper sulfate, 10 g of ferrous sulfate, 10 grams of zinc sulfate, 60 grams of green tea powder.
2 In the mid 30 days, the pig weighs 30 kg to 50 kg. Feed formula: 15 kg of corn, 10 kg of bran, 15 kg of hawthorn, 5 kg of rapeseed cake, 4 kg of bean cake, 1 kg of fish meal, 50 kg of rice bran, 200 g of salt, 25 g of copper sulfate, 12 g of ferrous sulfate, 10 g of zinc sulfate and 60 g of green tea powder.
3 in the late 30 days, pig weight 50 kg ~ 100 kg. Feed formula: 15 kg of corn, 10 kg of bran, 15 kg of hawthorn, 4 kg of rapeseed cake, 4 kg of bean cake, 1 kg of fish meal, 200 g of salt, 50 kg of rice bran, 30 g of copper sulfate, 15 g of ferrous sulfate, 10 g of zinc sulfate and 70 g of green tea powder.
Second, scientific management.
1 piglet before the fattening, use the insect repellent to clean the back of the pig's ear to expel the parasite; or take 1 gram of trichlorfon per 10 kg of body weight, feed the mixture.
2 feed fermented for feeding. Dissolve copper sulfate, ferrous sulfate, and zinc sulfate in warm water, sprinkle them evenly on the feed, add an appropriate amount of water to stir, and see the water with the fingers but not dripping. Then it is sealed in a cylinder or a wooden barrel, the temperature is maintained at 37~42 °C, the feed is fermented, and the feed can be fed when the wine emits aroma.
3 Fermented compound feed must be fed four times a day, the first time in the morning for 6 hours and a half, then every 4 hours, and the fourth time at 9:00. The amount of feed increased as the pig gained weight. Green feed is not limited. Feeding standards for compound feeds are: 1 kg to 1.25 kg per day for pigs from 15 kg to 30 kg; 1.5 kg for pigs per day for 31 kg to 50 kg; and 1.75 kg per day for 50 kg or more. Less feed, add water, feed after drinking.
4 According to the size of the pigs, the size of the pigs is raised to prevent the pigs from eating unevenly or eating and biting. The pigs should be conditioned to defecate and cleaned twice a day to keep the pig house dry. Raise to 100 kilograms.
Tangless Helicoil Inserts do not require a tang to complete the installation process and therefore, do not require breaking of a tang after installation resulting in spent coil sections for disposal. Instead, a Tangless coil Thread insert includes an insert-driving notch to aid in the installation process.
