Matching feed purchase
(1) according to the different broiler production purposes, different production levels and nutritional needs at different developmental stages, correctly choose the right compound feed;
(2) According to the label, check whether it meets the national quality standards and whether it is used within the specified warranty period;
(3) When using the feed produced by a certain manufacturer for the first time, it is best to carry out a feeding test to make scientific judgments on the quality of the compounded feed according to the appetite and health status, weight gain and feed consumption.
The concentrate consists of protein feed, vitamins, minerals and other non-nutritive additives. It does not include 60%-80% of the grain feed (energy feed). It is especially suitable for use in areas with a wide range of grain feed sources. The following points should be noted in the application:
(1) Choose a good manufacturer. Choose a reputable manufacturer and buy it from regular channels.
(2) Select the model number. There are many kinds of concentrated materials, different concentrated materials in different production stages, and different concentrations of concentrated materials in the same production stage. Therefore, be sure to read the instructions when purchasing, according to the proportions and varieties required by the instructions, add appropriate amount, do not make a mistake.
(3) Mix with the grain material must be sufficient.
A homogeneous mixture made up of different types of feed additives according to a certain formula, referred to as "premix" or "composite premix". Therefore, the premix has the added amount of almost active ingredients required by the broiler, and has a comprehensive additive effect. The following points should be noted when using the premix:
(1) To choose a manufacturer with reliable quality;
(2) selecting the appropriate concentration and the corresponding feeding stage;
(3) Accurate calculation of dosage, proper preservation, avoiding the loss of ingredients or the reduction of full price caused by long-term backlog;
(4) When preparing the feed, it must be mixed evenly.
Diesel Engine water pump is a common industrial equipment, which is widely used in agriculture, construction, engineering, fire protection and other fields. Its main function is to convert the power generated by the diesel engine into the power of water, so as to realize the delivery and supply of water. This article will introduce the working principle, structural characteristics, application fields and maintenance of diesel engine water pump.
The working principle of the diesel engine water pump is to use the power generated by the combustion capacity of the diesel engine to transmit the power to the water pump through the connecting rod mechanism, so as to drive the water pump to work. The working process of diesel engine water pump can be divided into three stages: water absorption, water pressure and drainage. In the suction stage, the diesel engine generates negative pressure through the up and down movement of the piston to draw water from the water source into the water inlet of the water pump; in the pressurized water stage, the piston of the diesel engine moves upwards to press the water into the pressurized water chamber of the water pump; in the drainage stage, the piston of the diesel engine moves downward to discharge the water from the outlet of the water pump.
