With the development of animal husbandry, the use of feed additives has spread to thousands of households. At present, various growth-promoting additives on the market, such as micro-ecological preparations, enzyme preparations, acidifiers, antioxidants, functional peptides, etc., and even some Products made with nanotechnology have their own benefits and promote poultry growth and development in different aspects.
However, in the production and use of feed additives, the following problems exist:
1. Abuse of antibiotics and hormones in feed additives In the early production of feed additives, low-dose antibiotics or sulfonamides were used to prevent diseases or diarrhea in livestock and poultry. This low-dose antibiotic will destroy the ecological balance between microorganisms (including pathogenic microorganisms) in the natural environment, and there are residues in food, which will seriously affect human disease treatment and human inheritance.
2. The amount of some trace elements is too much or insufficient. The trace elements commonly used in feed additives are iron, copper, manganese, zinc, iodine, selenium, etc. These elements enter the human body and are complex compounds with ions, molecules or structures. The state of existence, the biochemical effects in different states are also different. Too little will cause deficiency, too much will cause poisoning or imbalance. Therefore, the content must be appropriate and evenly mixed, otherwise it will have the opposite effect.
3, excessively exaggerated the role of feed additives, feed additives to balance the diet, promote the production and growth of livestock and poultry is affirmative. Generally, it can increase yield by 5%-25% compared with the control group without additives. However, some products exaggerate their role in advertising, and these unrealistic propaganda should be vigilant.
In short, any additive can only perform its intended effect when it is used reasonably. Farmers should rationally mix according to the various nutrients required by different growth stages of various livestock and poultry. According to the purpose of feeding, breeding conditions and health status, select reliable quality additives, and add them according to the accurate calculation of the instructions. use. It should be noted that livestock additives should not be used in poultry. Because the proportion of additives is very small, it must be fully mixed evenly in the compound feed to avoid excessive consumption and cause poisoning.
