Effect of Additives of Silybum Marianum in Some Growth Performance of Common Carp Cyprinus Carpio L.

Abstract

This experiment was conducted in the laboratory of Animal Production Department, College of Agricultural Engineering Sciences, University of Baghdad for the period for 3 months from 25/8/2019 in order to evaluate dried plant and seed meal of Silybum marianum as substitute to corn in feeding of common carp Cyprinus carpio L.. 14 aquaria with dimensions of 40 x 30 x 30 cm were used, with a capacity of 36 liters and 84 fish carp were distributed randomly with an individual weight of 2 ± 5 g / fish over seven treatments with a ratio of two replicates. Seven diets was made with iso energy and protein content and with different replacement ratios were from seeds Silybum marianum plant and powder, (5,10,15,20)% plants and 5%, 10% for seeds for the treatments T2, T3, T4, T5, T6 and T7 respectively, While as a control treatment which did not contain Silybum marianum powder, Fish were fed experimental diets at 6% of their weights. Growth parameters were calculated, . The results showed that the control and T4 treatments were the best. As they gave the highest levels for most of the studied traits. The results of the current study indicated that there was a significant different (P <0.01) between the control and T4 treatments with the other treatments in the rate of body weight, total weight gain, relative and specific growth rate. As for the best food conversion ratio treatment was T4. We have conclude from this study that there is an important role for Silybum marianum meal and seeds by add it to diets to improve growth parameters, which is reflected in the productive characteristics and improving their health status.

“…On the contrary, the addition of dietary SM seeds at a rate of 5-10% did not improve the growth performance of common carp, C. carpio L. (Al-Jubouri et al, 2021). Furthermore, the addition of SM to the diet of C. auratus gibelio at a level of 4 mg kg -1 diet did not influence growth performance or feed consumption (Yi et al, 2012).…”
