How to save feed for rearing ducks
Meat ducks have the advantages of fast growth, short feeding cycle, easy feeding, and less disease. At present, raising ducks has become one of the most important pillar industries for farmers to increase their income and make a good living. However, the feed cost of breeding meat ducks is high, and the feed cost often accounts for about 80% of the total feeding cost. Therefore, to improve the economic benefits of breeding ducks, it is crucial to reduce material consumption. Here are some ways to save meat for ducks: The meat ducks with excellent varieties and excellent quality have high genetic potential for production performance, fast growth, strong disease resistance, and high utilization of feed. At the same age, the same amount of feed is consumed, and its weight gain is much faster than that of other breeds of meat ducks. The suitable temperature for controlling the environment temperature of the meat duck is generally between 12 and 24°C, and the feed can be effectively utilized in this temperature range. Therefore, it is necessary to create conditions as far as possible, such as adopting winter greenhouses, summer shelters and other measures to keep warm and cool to increase feed remuneration. The balance of the diet is to “eat according to energy†for all poultry. When the energy level of the diet is high, the feed intake is small. When the dietary energy level is low, the feed intake is high. Therefore, the proportion of protein and energy in the meat duck's feed must be balanced. Otherwise, the consumption of feed increases, resulting in the waste of certain nutrients. For example, diets with low energy and high protein waste protein as energy consumption. The feed must be fresh and the raw material must be fresh. The second is to store the feed in a well-ventilated and dry place, and put a layer of moisture-proof material between the ground and the ground. Mixing materials should be used up as soon as possible, so that it can be fed with the ground to prevent the build-up and mildew. Mildew feeds are likely to cause poisoning in meat ducks, pull maggots, etc., thereby reducing feed utilization. In addition feed and duck houses should pay attention to pest control, rat damage and so on. Reasonable use of additives such as minerals, vitamins, amino acids, and other nutritional additives is necessary, and other non-nutrient additives are also helpful in improving the growth rate and feed utilization of meat ducks. Such as probiotics, enzyme preparations, organic acids, peptides, etc., have a significant effect on increasing meat weight gain and feed utilization. Feeding method should be reasonable and generally do not feed the original grain, raw grain smashing, with the granularity of the full-price material, can vary according to the duck's age, but should not be too fine, otherwise it is easy to fly and cause waste. When you add materials, you can't save time and add too much at once. In addition to the structure and height of the trough should be appropriate, we must also pay attention to timely repair troughs in order to prevent waste caused by leakage. Timely slaughter of meat ducks is generally suitable for slaughter in 40-48 days, because the weight gain and feed remuneration of meat ducks have reached a peak at this time. After 50 days of age, the weight gain of ducks decreased, and the feed rewards decreased. Therefore, timely slaughter is an effective measure to save feed. Imported Premium Chain Extender properties of the products. Chain extenders are alcohols or amines with low molecular weight multifunctional groups containing hydroxyl or amino groups. Common alcohols chain extenders include 1,4 dibutanediol (BDO), 1,6 dihexanediol, glycerol, trimethylolpropane, diethylene glycol (DEG), triethylene glycol, neopentyl glycol (NPG), sorbitol, diethylaminoethanol (DEAE), etc. Amine chain extenders include MOCA and formaldehyde modified liquid MOCA, ethylenediamine (DA), N, N-dihydroxyl (diisopropyl) aniline (HPA), etc. There is hydroquinone two (-hydroxyethyl) ether (HQEE), used as a polyurethane adhesive chain extender, its products heat resistance, hardness and elasticity are higher than the general use of chain extender.

Necessary reagents in the production of polyurethane, polyurethane is a prepolymer formed by the reaction of aliphatic and aromatic monomers containing diisonitrile with polyesters or polyethers containing binary or polyols. When applied, chain extenders are added to shape the resin. Common chain extensions are small alcohols containing binary or polyols, amino, iminoid, or ether alcohols.
