    Colostrum is a nutrient-dense fluid secreted by female mammals for the first few days following birth. Colostrum can be supplemented to poultry diets as a feed additive due to its nutritious and performance-enhancing properties. This study was conducted to determine the effect of dietary colostrum powder (CL-P, Alpha Lipid Lifeline Colostrum, New Zealand) on growing performance, carcass weight and yield, organ weights, serum vitamins and malondialdehyde (MDA) levels in quails (Coturnix coturnix japonica). A total of 90 birds, one day old, were divided into 3 groups consisting of 6 replicate cages, 5 birds per cage. Birds were randomly fed on one of three diets: basal diet and basal diet supplemented with 2.5% or 5% of CL-P. At the end of the period of 42 days, CL-P supplementation increased final body weight (P < .0001), weight gain (P < .0001), feed intake (P = .03), feed efficiency (P < .0001), carcass weight (P < .0001) and carcass yield (P < .01). Amounts of serum MDA (P < .001) levels also increased with increasing supplemental CL-P. As a result, growth performance can be improved and serum lipid peroxidation can effectively be attenuated by dietary CL-P supplementation at 5% of diets in Japanese quail.

    Effect of Supplementary Liquid Colostrum on Growth Performance, Carcass Yield, Ceruloplasmin, Sialic Acid and Some Antioxidant Levels in Quails
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2017) Baran, Murat Sedat; Bayril, Tahir; Akdemir, Fatih; Aksit, Hasan; Kahraman, Mucahit
    This study was conducted to determine the effects of supplementary liquid-colostrum (LiqC) on growth performance, carcass yield, ceruloplasmin, sialic acid, and antioxidant levels in growing quails. In this study, a total of 90 ten-days-old mixed-sexed Japanese quail chicks were used. Quails were divided randomly into 3 groups. Chicks were fed one of three diets: basal diet or basal diet supplemented with 2% or 4% liquid colostrum. Birds were exposed to a 14L: 10D illumination cycle for 32 (days of 10-42) days. When the effects of dietary liquid colostrum supplementation on performance were examined, values of final body weight, live weight gain, cumulative feed intake, feed efficiency, cold carcass weight and cold carcass yield in quails were higher in the trial groups compared to control group (P<0.05); but organ weights were not affected (P>0.05). Levels of liver malondialdehyde (MDA), ceruloplasmin, and sialic acid were lower, but levels of superoxide dismutase (SOD) were higher in trial groups (P<0.05), and there was no effect on total antioxidant status (TAS) levels (P>0.05). Serum MDA levels were lower and SOD levels were higher in liquid colostrum supplemented groups (P<0.05), although a numerical increase was found in TAS levels, no statistically important difference was found in trial groups. In conclusion, the oxidative, transport and slaughter stresses can be attenuated by liquid colostrum supplementation at 4% of diets in quail.
