Abstract
An experiment was carried out to determine the effect of replacing synthetic lysine (SL) with blood meal (BM) on apparent nutrients digestibility and hematological responses of broiler chickens. One hundred and fifty (150) unsexed Anak broiler chicks were used. There were five diets with diet (T1) containing 0.10% SL and without BM as control. Diets 2, 3, 4 and 5 contained 1.0, 2.0, 3.0 and 4.0% BM without SL respectively, representing T2, T3, T4 and T5 in the same order. The experiment was arranged in completely randomized design (CRD) with three replicates per treatment. Each treatment had 30 birds, 10 birds per replicate. Diets were isonitrogenous (23%CP and 20%CP) for starter and finisher phases and isocaloric (11.90MJME/Kg and 12.30MJME/Kg) for starter and finisher phases respectively. At the end of the experiment which lasted for 56 days (28 days for each phase), 4.0% BM significantly (P0.05) different at both phases. There was no mortality recorded in all the dietary groups.
Highlights
Broiler chickens remain the fastest source of animal protein because of their rapid growth
Maximization of productivity in broilers in form of heavy body weight with economical feed intake, is only achievable through the amount of good quality nutrients that are digested, absorbed and utilized by birds (Ndelekwute 2004).To achieve this, synthetic lysine is routinely added to chicken diets, because cereal grains and vegetable proteins which form the larger proportion of the diets contain limited lysine (D’Mello, 1993), and a major portion of the natural lysine in these plant feedstuffs are not available to the chicks (Prieto et al, 1994).since Odukwe and Njoku (1987) reported that synthetic lysine was imported and expensive in Nigeria this has not changed and increase in price has become more progressive currently
Influence of diets on nutrients digestibility and hematological parameters as shown in Table 3 for both starter and finisher phases indicates that significant difference occurred only for nutrients digestibility
Summary
Broiler chickens remain the fastest source of animal protein because of their rapid growth. Maximization of productivity in broilers in form of heavy body weight with economical feed intake, is only achievable through the amount of good quality nutrients that are digested, absorbed and utilized by birds (Ndelekwute 2004).To achieve this, synthetic lysine is routinely added to chicken diets, because cereal grains and vegetable proteins which form the larger proportion of the diets contain limited lysine (D’Mello, 1993), and a major portion of the natural lysine in these plant feedstuffs are not available to the chicks (Prieto et al, 1994).since Odukwe and Njoku (1987) reported that synthetic lysine was imported and expensive in Nigeria this has not changed and increase in price has become more progressive currently. The objective of this study was to compare the effect of replacement of 0.10% synthetic lysine with blood meal in broiler diets on nutrients digestibility and hematological parameters.
