As early as eating colostrum, eating enough colostrum due to as many as 6 layers of sow placenta tissue, while the immune antibody in the sow blood is a macromolecule glycoprotein, can not pass through the placenta into the piglets, so there is no birth of newborn piglets Immunity, it can not produce antibodies before 10 days of age, eating colostrum has important significance in the nutrition and immunity of piglets. Colostric effect: (1) It can provide special protein to prevent disease, which is due to the fact that sows provide γ-globulin or antibodies to fight disease; (2) The protein content is high, and it contains magnesium salts that can relieve diarrhea. Promote meconium excretion; (3) High acidity can compensate for imperfect digestive tract and impaired digestive gland function in newborn piglets; (4) Although macromolecular compounds of immunoglobulins are not available from 18 hours to 24 hours after birth The intestinal wall absorbs directly, but the various nutrients of colostrum within a few hours of being born are absorbed almost entirely in the small intestine, which is beneficial to the growth of physical strength and warmth. (5) Supplementary energy If the piglets cannot be established after the first time, the liver glycogen stored in the body rapidly decomposes and declines. If the blood sugar is too low and the piglet died, within 24 hours after birth, it should be able to ingest 0.25 liters of colostrum. Ensure its energy supply. Influencing factors: Colostrum quality and composition Colostrum is a very complex substance, and each ingredient plays an important and special role. The amount of colostrum secreted: Within 24 hours after delivery, the sow can only secrete 1200 grams of colostrum, which is not enough to supply a single piglet. Precautions: Piglets should eat colostrum early and eat colostrum in order to obtain enough antibodies. Normally, it is best not to exceed 2 hours from the time of birth until the first time to eat colostrum. The piglets are given breastmilk once every 1 hour and gradually extended to 2 hours or longer. After 3 days, the sow can be breast-fed. Solutions for Colostrum Insufficiency: Prepare Colostrum Replacement Mix 10-15 kg of cold water at 40°C per kilogram in the non-sows suckling suckling pig's nutritional milk powder. Stir well and add 1-20 ml of porcine antibody serum. Replace colostrum with colostrum replacement instead of colostrum can solve the problem of colostrum insufficiency; the application of this technology can save the sow's lactation period and increase the production efficiency of sows; and reduce the stress of weaning pigs caused by weaning. , can greatly reduce the production costs of suckling pigs, improve the economic benefits of suckling pig production.
Sun-Shading Net is a series of colored shade
nets with special optical properties which improve the utilization of solar
radiation by agricultural crops. This technology promotes differential
stimulation of desirable physiological responses, which determine the
commercial value of each crop. This is an economical and environmentally
friendly alternative to current labor-consuming methods (such as pruning and
thinning) and intensive use of growth regulators and other chemicals.
ChromatiNet enables growers to control vegetative growth characteristics, such
as leaf size, branch length and plant height in plants, as well as the rate of
maturation and flowering. This enables adaptation to market preferences, with
clear economic advantages.
Greenhouse Sun-Shading System can reduce solar load, and cool down the inside temperature and create a comfortable environment for the plants.
