There are large quantities of agricultural wastes available annually in Egypt - economically unexploited agricultural by-products, the most important of which are hay, rice straw, wood and green thrones.These can be used as animal feeds after mechanical, chemical or biological treatments to increase their nutritional valueEspecially since most of these residues are low in crude protein and high in fiber and cellulosic substances that decrease digestion and palatability when feeding animals without any treatment.It is estimated that the total amount of agricultural residues in Egypt ranges from 13-15 million tons per year, although there is a deficit in coarse feed estimated at 4.5 million tons and aims to develop livestock in Egypt to eliminate the current gap in animal products,Average annual per capita consumption of domestic livestock products is estimated at about 12 kg of red meat, 8.6 kg of poultry meat, 10.2 kg of fish, 71.9 kg of milk and 3.9 kilograms of eggs according to 2016 estimates, well below the average consumption in many developing countriesThe lack of feed resources is a major constraint to the development of livestock in Egypt, where it is estimated that the balance of feed (the relationship between feed needs and available feed resources) that Egypt suffers an annual shortage of about 3.5 million tons of digested food T. D.N, Poultry and animals, the cost of the state about 13.7 billion poundsTherefore, about 6.8 million tons of maize were imported in 2015 to be used in the manufacture of feedstuffs. It is estimated that the value of animal production requirements is estimated at 68 billion pounds, representing about 72% of the total value of agricultural production requirements estimated at 94.6 billion. Pounds,This leads to an increase in the cost of local resources as a result of the high prices of livestock inputs.This leads to the contraction of domestic supply in light of the liberalization of foreign trade as a result of the competition of imported meat, where increasing quantities of imported red meat for low prices, as previous studies indicate the relative importance of the costs of feeding dairy animals, which represents about 72% of the average total .
