Brief analysis of the role of adding fish oil in feed!

Fish oil is a by-product of fishmeal processing is obtained by steaming, pressing separating fish their wastes.

The main components of fish oil are: triglycerides, phospholipids, lipids lipid solubility, vitamins, protein degradation products, etc. No toxic substances such as mercury, arsenic lead were detected in Marine fish. Potassium, copper, aluminum cadmium were all below the allowable values. Pesticide residues were almost zero. Therefore, the quality of fish oil processed fish their wastes is reliable.

1. A gram of protein has twice as many calories as a gram of carbohydrates. The digestibility of animals is high. It was proved that the total utilization rate of fish oil eel bait was more than 90%. After absorption, animals are mainly converted into energy for activity consumption, improve the available energy in the feed, reduce part of the protein as energy consumption, so as to save protein, improve feed energy, reduce feed cost, promote animal growth development.

2. Phospholipids in fish oil are indispensable components of animal brain, nerve tissue, bone marrow, heart, liver, egg spleen.

At the same time, it is beneficial to the digestion, absorption formation of lipids. It is also an important structural material for biofilms.

3. In addition to providing animals with essential n-3 long-chain polyunsaturated fatty acids, refined fish oil is also used as a carrier of fat-soluble vitamins A, D carotenoids. Vitamins are absorbed used together with fat-soluble substances. Animals lack of essential fatty acids can lead to stunted growth, reproductive function decline, the skin water swelling, bleeding, body color dim, etc., especially can increase the content of n - 3 fatty acids in diet, these fatty acids can reduce prostaglandin, thus improve the level of animal antibody production, saving livestock antibiotics usage, to heal disease prevention.

Linoleic acid in fish oil affects the size of the egg, but has no effect on the oil content of total fat in the yolk, but affects the level composition of fat in the liver. Linoleic acid is a key factor in controlling the synthesis of lipoproteins in the liver, which travel through the blood to the ovaries form bubbles, which control egg size. It has been shown that consuming 2.75 grams of linoleic acid per layer significantly increases egg weight. In addition, adding fish oil to the diet of laying hens can reduce cholesterol levels in eggs by 20 percent, so that people who eat eggs do change their blood cholesterol levels, which can be increased by eating regular eggs.

The laying rate of laying ducks is generally about 80% in the peak period, will drop to about 605 after the peak period. According to the report, this phenomenon is related to the lack of fat, vitamin, protein amino acid nutrition in the diet, which is just made up by the fish oil capsule. If 2% fish oil was added after the peak laying period, the laying rate could be increased to about 73% the average income per feather increased by 70%.

Adding FISH OIL which ACCOUNTS FOR 3% ~ 5% OF TOTAL FEED IN feed processing can improve feed nutrition, promote biological growth, improve the meat quality of fish livestock in aquaculture industry, prevent excessive animal fat. In addition, fish oil has a strong fishy taste a strong food appeal. In addition, fish oil contains large amounts of fat-soluble vitamins a D, which can ensure the comparative needs of livestock aquatic animals.
