Effect of different levels of feed added coriander (coriandrum sativum) leaves meal on the performance, carcass quality, immune response and blood profile of quails (corturnix cortunix japonica)

Abstract

An experiment was conducted to study the effect of different levels of feed added Coriander sativum leaf meal (CLM) on the growth performance viz., weight gain, feed intake and feed conversion ratio, carcass characteristics, immune response and some blood parameters of quails. One hundred and eighty (one week) old Japanese quails were used for this study, the birds were reared in a wooden cage with dimensions of 1 × 1 × 0.4 m (length, width, height). They were divided into four dietary groups and each group was subdivided into three replicates of fifteen quails each. The groups were assigned to four diets containing 0, 2.0, 4.0 and 6.0% CLM. Feed and water were provided ad libitum throughout the experimental period which lasted for 8 weeks. The results showed that there was a no significant (P>0.05) difference in body weight, weight gain and feed conversion ratio between treatment groups. The relative weights of the organs examined were not significantly (P>0.05) different across dietary treatments. All the hematological and serum biochemical parameters evaluated: Pack cell volume (PCV), Hemoglobin (Hb), White blood cell (WBC), Mean corpuscular volume (MCV), Mean corpuscular hemoglobin (MCH), Mean corpuscular hemoglobin concentration(MCHC), Albumin, globulin, Aspartate aminotransferase (ALT), Alkaline phosphatase(ALP), Glucose, Urea serum glutamic oxaloacetate transaminase (SGOT) and serum glutamic pyruvate transaminase (SGPT) were not significantly (P>0.05) affected by the inclusion of CLM. Significant influences (P<0.05) were observed for immune response and mortality. The results of this experiment demonstrated that CLM can be included up to 6.0% level in quail rations without any adverse effect on growth performance, carcass characteristics and blood profile of birds.
