Effect of the use of exogenous fibrolytic enzymes in blood parameters in local goats

Abstract

The study was carried out in the ruminant researches station / department of livestock research section / office of agricultural research in the district of Abu Ghraib / Baghdad to assess the effect of exogenous fibrolytic enzyme (EFE) (Safizym - France) in blood characters of local male kids. The experiment was conducted during the period from 21 May 2017 to 17 July 2017 (57) day. Eighteen males of domestic goats aged 4-5 months were used in this study. The animals were randomly assigned to three treatments (6 animals for each treatment) a control treatment was fed on basal ration without enzyme (Tc), a treated groups were supplemented with the EFE of 500 g / ton of concentrate feed (T1) and a treatment with the EFE of 1000 g / ton of concentrate feed (T2). The results showed no significant effect of the adding with EFE in the total protein, albumin and globulin, while there was an effect of the period of the weeks in the T1, where the superiority (P≤0.05) of the eighth week. The results showed a significant differences (P≤0.05) in the serum urea concentration. The second treatment decreased during the second and sixth weeks compared to the T1 and the control Tc. There was an effect of the period of the weeks within the same treatment, where all means in all treatments were reduced with progress the time of the experiment. The results showed no significant effect of the adding with EFE in both glucose and cholesterol. The means were within the normal range and the triglycerides were not affected but there were differences between the weeks within the treatment. Concentrations of HDL, LDL and VLDL were not affected by the addition of EFE, but significant differences (P≤0.05) were observed between the weeks within the treatments. The results showed that T2 treatment was superior during the zero time in the concentration of the ALP enzyme for T1 and Tc, and significant differences between the weeks within the treatments. T1 treatment (P≤0.05) exceeded T2 and Tc in the concentration of the ALT enzyme during the zero time and the fourth and sixth weeks with no effect for the period of the weeks within the same treatment. The treatment and period of the weeks did not affect the concentration of AST enzyme in the serum.
