These feeds cannot feed pigs

Piled up for a long time with heat and rotten succulent vegetables, juicy vegetables and grass, long-term storage or keeping the pot closed at a low temperature of about 50°C for a long time, all can promote the rapid propagation of nitrogen bacteria, which will be contained in succulent vegetables and grasses. Nitrate is reduced to nitrite and the pig feeds on poison. When green feeds must be cooked freshly, they should be filled with the fire, boiled quickly, uncover the lid, and do not stay in the pot overnight. Mildly deteriorating feeds such as corn, wheat bran and compound feeds are wet and moldy. After eating pigs, a variety of mold poisonings will occur, usually about 10 days. Acute poisoning performance is dull, does not eat, the hindquarters are weak, the mucous membrane is pale, the body temperature is normal, the feces is dry. Sometimes present with neurological symptoms, stand upright or reach under the wall. Chronic poisoning is apathetic, walking is stiff and heterophobic. Often left alone, head down, bow back. There are also symptoms such as excitement. Visible yellow smear. Do not feed moldy, rotten corn, wheat bran, and compound feeds to find poisoning. Immediately stop feeding and feed green and easily digestible feed. The poorly preserved distillers' grain is poorly preserved, the lees are poorly smashed, and a small amount of ethanol remaining inside fails to form acetic acid. A large number of long-term feeding pigs can easily cause acetic acid poisoning. Gastrointestinal symptoms, abdominal pain, and diarrhea were mainly present during acute poisoning. Chronic poisoning has dyspepsia, jaundice, dermatitis, hematuria and other symptoms. When severe, the paralysis collapsed and died. Pregnant sows often cause miscarriage. Distillers' grains should be mixed with other feeds. Do not add more than 20% of the fresh distillers' grains in the feed. Distillers dried grains must not exceed 10%. Dirt avoid feeding pregnant and lactating sows, and avoid feeding pigs.

Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.

       The advantages are as follows:

    (1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
 
    (2) Saving labor and operating expenses.
 
    (3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
 
    (4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
 
       classification:

       First, fully automated Irrigation System

       The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
    
       Second, semi-automatic irrigation system

       In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.

       Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
