The effect of partial substitution of roasted soybean seed with graded levels of sweet potato (Ipomoea batatas) leaf meal on growth performances and carcass characteristics of broiler chickens

Abstract

This study was designed to assess the effects of partial substitution of roasted soybean seed with sweet potato (Ipomoea batatas) leaf meal (SPLM) on growth performances and carcass components of broiler chickens. The experiment was a completely randomized design consisting of five dietary treatments replicated four times with ten chicks each. The control diet (treatment 1, T1) contained roasted soybean seed as the major protein source without SPLM and treatment diets containing SPLM at the levels of 30 g/kg (treatment 2, T2), 60 g/kg (treatment 3, T3), 90 g/kg (treatment 4, T4) and 120 g/kg (treatment 5, T5) by partially substituting the roasted soybean seed in the control diet. The results indicated that the body weight gain in chickens reared in T1 was (p<0.01) higher than those fed on T3, T4 and T5 diets. The individual feed intake in chickens reared in T1 was (p<0.001) higher than those fed on other treatment diets. The feed conversion ratio (kg feed/kg gain) of chickens fed on T1 was (p<0.05) lower than those reared in T4 and T5 diets. Chickens fed with T2 diet had numerically higher values of slaughter, dressed carcass and breast than those reared in T4 and T5 diets. It can be concluded that the partial substitution of roasted soybean seed with sweet potato leaf might be economically feasible feeding strategy of broiler chickens in smallholder poultry farm settings.

Effect of Vegetable Waste on Growth Performance and Hematology of Broiler Chicks

“…But the lungs and large intestine are nonsignificant ( P > 0.05) among different dietary treatments described in Table 6 . This study agreed with the result of Melesse et al [ 27 ] who observed the broilers who fed on ( T 2 ) (30 g/kg SPLM) had higher slaughter weight and things weight. The current study shows controversy with Mozafari et al's [ 28 ] work who used the different level of cooked and raw potato replacing with 25 and 35% seed of maize which reported that the dietary treatments had nonsignificant effect ( P > 0.05) on weight of thighs, breast, and liver of broiler chicks.…”

“…A healthy diet should contain 1-2% of its calories from fat, according to various theories. This is because the low crude fat content of the young shoot of Urtica simensis shows that it might shield people from chronic diseases [ 25 ]. The leaves of Erucastrum abyssinicum had the least crude fibre content (7.80 ± 0.2 g/100 g), whereas the crude fibre content of Rumex abyssinicus was (34.70 ± 0.25 g/100 g).…”

“…The treatment was better compared to control (219.20 (T1), 200.10 (T2), and 215.30 (T3) vs. 243.30 U/L). Melesse et al, (2017) stated the criteria GOT were at the number less than 40 U/L. The result of the GOT may be due to M. oleifera content.…”
