Abstract

Small animal farms are currently adding and mixing of feed materials manually, which may cause wasting the amount of it. Transfer and delivery of the mixed animal feed to feedlots may be causes the difficulty of achieving distributed recommended ratios of feed mixing operation. Some of the interactions between the components may occur after leaving period which may cause rot and damage to the feed materials.  Grinded (concentrated) animal feed is difficult to add directly in the form of powder separately.  Preferably mixed them with roughage materials and adding feed materials blended automatically. To obtain the mentioned aim, locally manufactured machine achieved mixing and adding at the same time with recommended ratios obtaining a little bit losses of feed materials. To performance and evaluation of new machine, experimented in the animal farm at the three different tested factors. Four forward speeds (Fs1 = 1.2) & (Fs2 = 2.2) & (Fs3 = 3.1) & (Fs4 = 4.2) km/h., Four opening hopper gate ratios (roughage feed material gate : concentrated feed material gate) (G1 = 1:1) & (G2 = 1:2) & (G3 = 1:3) & (G4 = 1:4) and three Revolution ratios (Mixing auger revolution : stirring shaft revolution) ( R1 = 1:1 ) & ( R2 = 1:2 ) & ( R3 = 1:3 ). The animal feed adding rate as kg to one longitudinal meter of feedlot (kg/m), mixing quality of animal feed materials were measured. The obtained results showed that, the new machine works properly at lowest forward speed (Fs1 = 1.2 km/h) with deferent other treatments under study, but the optimal quantity of feed additives by machine 16 kg/m achieved with (R2 = 1:2), also new machine had highest efficiency of animal feed mixing process quality with all treatments under study specially with (G3 = 1:3)
