Fish meal is an excellent source of protein easily digestible, rich in omega-3 fatty acids (EPA and DHA) and essential vitamins and minerals (IFOMA, 2001). Quality fish meal depends on the ingredients used and the method of processing involved.

Fish meal is considered to be a useful source of protein among existing animal proteins. It is one of the most prominent animal proteins, contributing to the balance and assimilation of amino acid constituents.

Lack of protein in the diet, animals will grow slowly, effective use of food is low.

Animal diets lacking protein or protein in the development stage of the slow-growing and susceptible to disease, during maturation, lack of nitrogen, Meat, such as pork and chicken, has only bones with very few flesh, but the meat does not taste good, in reproduction, mating and conception poorly, giving birth to a baby or small egg, spawning, Less milk, less prone to death.

-Fish meal is a source of Rumen Degradable Protein and is therefore used as a protein by-pass. Use Fish Meal for Food Feed Dairy cows, as compared to undegradable protein sources such as soybean meal or cottonseed meal, produced higher fish meal (Broderick, 2005; Broderick et al., 2000; Korhonen et al. Improvement of amino acid balance and reduction of N secretion (Ohgi, 2004; Abu-Ghazaleh et al., 2001; Schroeder et al., 2000).

Cows reacted with fishmeal proteins were improved by treating urea in a rice-based diet (Talukder et al., 1990; Khan et al., 1990). Fish meal increased milk yield and protein yield in cow's milk (Malleson et al., 2008, Ibarra et al., 2006; Broderick, 2004; Ohgi, 2004; Yeo et al., 2003; Korhonen et al., 2002; Hill et al., 1999; Wright et al., 1998), especially if the rate of feed / concentrate is high (Pike et al., 1994). However, some reports suggest that it did not affect milk yield or milk protein content (Moussavi et al., 2008 and 2007; Serbester et al., 2005; Allison et al., 2002).

Fish meal was also added to cattle to meet the high frequency of lactation (Yeo et al., 2003). And lowering levels of PGF2α may have affected early miscarriage in cattle (Mattos et al., 2002), because Thus higher conception rates (Staples et al., 1998). Feeding of fishmeal may also increase n-3 fatty acid content (Abu-Ghazaleh et al., 2001)

-Use fish meal for sheep

The unrestricted protein content of fishmeal is excellent in sheep because it increases feed intake in sheep from 2.5% in sheep to 7.5% in sheep (FIN, 2000).

High protein content improves immunity status: breeding late-fetal females with reduced fish meal and thus reducing anthelmintic treatments (Donaldson et al., 1998).

Fish meal supplementation increases the reproductive performance in female sheep: conception rate, litter size, lamb weight, lamb life at birth, colostrum and oestrus production (Vipond et al. Robinson et al., 1989; Robinson et al., 1999).

Lactating mothers with fishmeal supplement had higher milk yields. Fish meal was also improved to increase the high survival rate of weaned sheep (Poppi et al., 1988)

-Use Fish Meal for Pigs

Use Fish meal as food for pigsThe fish has high biological value for pigs. Protein of fish meal is of good quality: it has a high content of methionine and easily digestible protein. Its composition includes vitamins, fatty acids n-3 and minerals are very valuable for pigs. The level of company establishment varies from 5 to 10% in adult pigs or sows (piglets eat about 3%) (FIN, 2000; Patience et al., 1995).

Various studies have demonstrated that fish meal is beneficial for pigs that start feeding and weaners (Lopes et al., 2007; Zivkovic et al., 2007; Kats et al., 1992; Aas et al. 1984) at less than 10% (higher rates result in loss of economic efficiency) (Patience et al., 1995).

Fish meal was also reported to be hypoallergenic to piglets and was found to reduce diarrhea during postweaning (Gore et al., 1990). It may be useful for improving low-level health in piglets daily (Bergstrom et al., 1997).

-Use Fish meal as food for Poultry

Use Fish Meal for Poultry Fish meal is an attractive protein source for poultry. Fish meal has a high biological value in poultry, not only as a source of protein but also as a source of minerals such as P, Ca and trace elements such as Se or I. However, Consumption and a rate of around or under 5% of diet ingestion (Blair, 2008; Chadd, 2008).

Including fish meal in the chicken diet increases body weight gain, daily weight gain and increased intake. Fish meal has a greater effect on broiler growth than it was at the beginning. It works for both small turkeys. Using lamb meal for chicken laying can cause a fishy smell in eggs and meat. (Blair, 2008).

-Use fish meal as rabbit food

Fish meal is a valuable feed for rabbits. Due to its cost, there have been many attempts to replace it with less expensive products: it was able to completely or partially replace fish meal with quinoa, blood meal, waste products from incubator plants Eggs, meat meal and poultry organ meal (Lebas, 2004).

-Use fish meal for seafood

Use fish meal for fish. Fish meal is an essential amino acid supplement, ideal for fish or shrimp, a major source of protein for aquaculture. Protein digestibility of good quality fish meal is very high in amino acids (Anderson et al., 1995). Fish meal is also an essential source of essential fatty acids, minerals and trace elements.

Existing data show that of the 6 million tonnes of fish meal available globally, over 65% is used in fish and crustacean feeds. Combination levels of fishmeal may range from 40-60% in marine fish feeds to less than 5% in carp, catfish and tilapia feeds (Tacon et al., 2008).

Most cyprinids cultured in semi-intensive ponds are fed with virtually no fish meal. In recent years, much progress has been made towards replacing fish meal with a mix of different vegetable protein sources, even in salmon or marine fish farming, thus leading to significant economies of scale. Issues of sustainable development (Kaushik, 1990; Kaushik et al., 2004; Kaushik et al., 2008).
