Thus, a gap was created and had to be filled by improving meat and dairy products and this policy has put a large borden on the Egyptian economy. As dairy animals, buffaloes are rated the first as they produce 1.4 rrillion tons of rrilk i.e 65 % of the total national production of milk. Besides they produce 149000 tons of red meat (45.6 % of ~he national produc~icn of red ~eat). The prices of animal products are also gating higher and being affected by the increase demand for consumption and the increased prices of feedstuffs. In addition, the quantity of feed stuff in Egypt become below ~he demand and its price is progressively increasing during ~he few last years. from an econonical point of vie~ it is better to use animal feeding s~uffs which are cheeper broiler litter has been and locally produced. The dried largely used in the last decades because it was considered very rich in differed nutrients. The present study was carried ou~ ~o investigate the effect of replacing different levels of the crude protein of the concentrate feed mix~ure by dried broiler lit~er on heifer’s growth and some reproductive performance. |
