Perilla, both food and medicine, can develop a variety of health foods. Its leaves, stems and seeds can be used as medicines, and has a wide range of uses in medicine and food industry. In recent years, basil has gradually been used as a feed additive to breed animals, and the effect is good. The Ziyue Yousheng feed additives approved by the Ministry of Agriculture are particularly prominent, which can promote animal growth, improve production performance, improve animal product quality, and prevent diseases. effect.
The following experiments are conducted: The effect of Ziyueyousheng, a feed additive of Perilla seed extract, on the growth performance of weaned piglets was studied using weaned piglets.
A total of 22 weaned piglets weighing approximately 6 kg were selected and the weaning days were 28 days. The weaning piglets were divided into experimental and control groups. The test period was 30 days. The control group was fed the basal diet, and the experimental group was supplemented with basal yolk eugenics in the basal diet. The basal diet was a twin piglet pellet.
From the start of the trial, the piglets were observed and recorded daily for mental status, diet, defecation, and death.
Both groups of weaned piglets had diarrhea, 4 had diarrhea in the control group, and medications had diarrhea. Diarrhea was cured 5 days later. In the experimental group, there were 3 diarrhea cases, one of which was diarrhea during feeding, and the body weight was smaller. No treatment was given. After 3 days of feeding Ziyoushengsheng, the diarrhea of ​​the piglets in the experimental group began to improve, and the smallest one was fed. Increased, the fur is also soft and smooth from the previous mess. After feeding for half a month, the piglets in the two groups were observed. In the experimental group, the piglet skin was softer and brighter than the control group.
After the end of the trial, the weight of the two smaller groups in each group was removed. The daily gain of the test group was 5.8% higher than the control group, and the feed weight ratio was reduced by 4.56%.
From the test results, the overall effect is good. The diarrhea piglets in the experimental group with Ziyueshengsheng supplementation were able to self-heal without additional drug treatment, and the fur was soft and bright, and the growth rate increased, which significantly increased feed remuneration. It follows that Ziyueshengsheng has a preventive effect on diarrhea in piglets, and it helps diarrhea piglets to recover as soon as possible.
Everything You Need To Know About LED Lighting
LEDs are a simple invention with huge potential to change the lighting industry for the better. Don`t know much about them? Here are three big things you need to know to get your feet under you:
1.What Does LED Stand For?
2.LED stands for light-emitting diode.
A diode is an electrical device or component with two electrodes (an anode and a cathode) through which electricity flows - characteristically in only one direction (in through the anode and out through the cathode). Diodes are generally made from semi-conductive materials such as silicon or selenium - substances that conduct electricity in some circumstances and not in others (e.g. at certain voltages, current levels, or light intensities).
2.A light-emitting diode is a semiconductor device that emits visible light when an electrical current passes through it. It is essentially the opposite of a photo-voltaic cell (a device that converts visible light into electrical current).
Did You Know? There is a similar device to an LED called an IRED (Infrared Emitting Diode). Instead of visible light, IRED devices emit IR energy when electrical current is run through them.
1.How Do LED Lights Work?
2.It`s really simple actually, and very cheap to produce, which is why there was so much excitement when LED lights were first invented!
The p-type and n-type materials are created by introducing the original material to atoms of another element. These new atoms replace some of the previously existing atoms and in so doing, alter the physical and chemical structure. The p-type materials are created using elements (such as boron) that have less valence electrons than the intrinsic material (oftentimes silicon). The n-type materials are created using elements (such as phosphorus) that have more valence electrons that the intrinsic material (oftentimes silicon). The net effect is the creation of a p-n junction with interesting and useful properties for electronic applications. What those properties are exactly depends mostly on the external voltage applied to the circuit (if any) and the direction of current (i.e. which side, the p-type or the n-type, is connected to the positive terminal and which is connected to the negative terminal).
Application of the Technical Details to LED Lighting:
When a light-emitting diode (LED) has a voltage source connected with the positive side on the anode and the negative side on the cathode, current will flow (and light will be emitted, a condition known as forward bias). If the positive and negative ends of the voltage source were inversely connected (positive to the cathode and negative to the anode), current would not flow (a condition known as reverse bias). Forward bias allows current to flow through the LED and in so doing, emits light. Reverse bias prevents current from flowing through the LED (at least up until a certain point where it is unable to keep the current at bay - known as the peak inverse voltage - a point that if reached, will irreversibly damage the device).
