Use points of piglet feed additives
With the acceleration of the pace of modern life, the progress of a civilized and harmonious society, the quality of life concepts has been continuously improved, and the health of animal-derived foods has caused concern of the state and society. The scientific hygiene and food safety of the pig industry have also attracted the attention of consumers. Not only do the pig facilities need to be improved and improved continuously, but also the living environment of pigs is required to be standardized, and the feed and additives of pigs are micro-ecological. The use of Chinese herbal medicine - Astragalus and Ginkgo, micro-ecological preparations such as probiotics, chlorella, Bifidobacterium, bacitracin zinc, oligomerization, bioactive oligopeptide sugar, yeast powder and other new additives to prevent drug residues. Achieve safe farming without pollution, pollution and environmental protection. We will use micro-ecological preparations to improve the quality of pig production and food hygiene. The industry needs to master the continuous learning and updating of breeding technology, and scientifically master and apply the technology of adding pig feed drugs. The main links must master the following points.
1. The principle of matching piglet feed additives
The growth rate of piglets is determined by the nutrition of the feed. Nutrition is the material basis for the growth of pigs. The nutrients required for their functions should be divided into five categories. The lack of which type will cause the growth of piglets to slow down or become sick, causing serious death. Therefore, it is crucial to pay attention to the type, quality and management of feed. How to choose feed and pharmaceutical additives is the key to promote the growth of piglets. Specifically, 1-3% of oils are added to resist oxidation, broad-spectrum antibiotics are antibacterial and anti-parasitic, and probiotics are promoted by zinc. Strictly according to the growth stage, the standard mix feed is used. The scientific pig raising is to manage the pig's life in several stages. The piglet feed is used in the piglet stage, and the feed of the weaned piglet is characterized by the flavor. You can add egg acid and lysine, or stir fry. Cooked soybeans and soy flour should be added with pepsin due to lack of digestive juice. The shelf pig's feed is characterized by a salty taste and can be added with fishmeal. Sows can add feeds such as syrup and yeast to help digestion, increase appetite, promote transformation, and grow faster.
2. Characteristics of common drug additives for piglets
Oils and fats are widely used, and there are many types of fats and oils used in feeds, and they are also fixed components contained in feeds, and the difference is in the amount contained. Cake feeds such as bean cake, peanut cake, cottonseed cake, and sunflower cake have different oil content, at least between 3-8%, and the formulated feed should be compatible with the proportion of added vitamins, which may cause rancidity. Especially in the summer when the temperature is high, the effect of rancidity is large to prevent the oxidation process. Adding fat to the feed can improve the utilization rate of the feed, especially for the piglets after weaning. It improves the taste of the piglets and promotes the appetite of the piglets. It is an additive that must be added to the feed of piglets. If fat is lacking, it will cause The lack of essential fatty acids, accompanied by the lack of fat-soluble vitamins, such as VA, VD, VE, VK, these four essential vitamins, fat-soluble vitamins that can not be synthesized in piglets, the amount of piglets in the feed will grow Fast, the hair is bright and the appetite is constantly increasing. If not enough, there will be deficiency, such as loss of appetite, indigestion, and slow growth. Severe can become stagnant or cause death.
3 antibiotics: There are many types of antibiotics. The broad-spectrum oxytetracyclines and sulfonamides used in piglet feed are often used for dyspepsia enteritis, prevention of chronic parasites, and also for promoting and fattening. In view of the damage to the kidneys, the residues in the meat, and the harm to the carnivores, the Ministry of Agriculture has implemented restrictions on the use of bacteriostatic food safety standards. Newly formulated and revised standards, including food contaminants, pathogens and pesticide residue limits, use of food additives, general hygiene standards for food production, and other food safety national standards, as well as related food standards, hygiene in production and operation processes Requirements and supporting inspection methods to limit application. Scientific experiments have shown that the addition of Chinese herbal medicine can replace antibiotics, promote growth and prevent infectious diseases. The piglet stage controls the infectious disease, and there is no need to worry about growing in the fattening stage.
4 micro-ecology: mainly beneficial bacteria in the intestine, containing peptides, enzymes, sputum, amino acid vitamins and minerals, is an ideal drug-free residue, can replace protein additives. Such as probiotics, bifidobacteria, Bacillus subtilis, yeast, sputum. Due to the fast growth of piglets, it is necessary to have complete nutrition and a small number of intestinal microbes. It is necessary to supplement from the outside. Most farmers use yeast and fertilizers. Nowadays, chlorella is popular. Chlorella is a new high-tech additive. Chlorella has the characteristics of heat resistance, acid resistance and antibiotic resistance. It is very suitable for feeding piglets with feed. It is rich in essential amino acids of protein. The use and addition method of chlorella is the same as that of probiotics.
5 Chinese herbal medicine additives: There are many kinds of Chinese herbal medicines for feeding pigs, mainly including Buzhong Yiqi. The Buzhong Yiqi Fertilizer mainly contains Astragalus, Angelica, Chenpi, Pumpkin, etc. The herbal medicines in this formula are widely available. It is also cheap, and it has the effect of deworming and fattening the bloody stools, and the effect is particularly obvious. There are a lot of pigs in this town who use this side. The piglets are fed quickly and the disease is high, and the income is high.
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.
