The Effect of Different Levels of Spearmint (Mentha Spicata) Extract on Immune System and Blood Parameters of Broiler Chickens

The study determined the effect of three different levels of Boswellia serrata tree resin (BSR) supplementation in diets for broiler chickens on the growth performance, selected slaughter analysis, nutrient digestibility, as well as haematology, biochemical and some humoral immunity blood parameters. In total, 200 1-day-old broiler chickens were assigned randomly to four treatments. The broiler chickens were fed diets containing 0 (C), 1.5 (BSR1.5), 2 (BSR2), or 2.5% Boswellia serrata resin (BSR2.5). The BSR treatments improved (P < 0.05) the feed intake and feed conversion ratio at breeding Days 22–35, but did not differentiate the nutrient digestibility in the diets. The best-quality carcass with a high proportion of muscles and low fat content (Control versus BSR diets, linear, P < 0.05) was obtained in broiler chickens fed diets supplemented with 2% and 2.5% BSR. The blood profile was affected by the BSR treatments. The lymphocyte count increased linearly in blood (P < 0.05) along the increasing amounts of BSR. The content of uric acid and aspartate aminotransferase activity in blood plasma decreased upon the BSR supplementation (Control vs BSR diets, linear, P < 0.05; and Control vs BSR diets, linear, P < 0.01, respectively). The resin of Boswellia serrata can be considered as a good botanical feed additive, which can have positive effects on the performance and health of broiler chickens.

Different Levels

The use of herbs and spices has gained increasing interest as feed additives and possible alternative to antibiotics in poultry production. The effects of using different levels of coriander seed powder or extract on selected blood parameters, intestinal microflora, and immune response of broiler chickens were investigated in this study. A total of 420-day-old broiler chicks were randomly assigned to 7 treatments with 4 replicates and fed for 42 days. Results showed that inclusion of 2.0% coriander powder in broiler diets lowered total cholesterol while blood urea was significantly higher in birds on T4compared to T1and T2. Furthermore, there were no treatment effects onLactobacillusbacteria; however, the population ofE. coliwas significantly higher in the ileum of chickens fed T0. Noticeable significant improvements of antibody titer against Newcastle, infectious bronchitis, and infectious bursal disease were observed in birds receiving coriander extract in water. Immunoglobulin G antibody against sheep red blood cells showed significant improvement in birds fed T3; likewise, immunoglobulin M was significantly higher in birds on T2and T3at 28 d of age. These results revealed that coriander extract or powder can be used as antibiotic alternative in broiler feeds.

Abstract This study was performed to investigate the effect of different levels of aspirin on the diet of broilers. The experiment was conducted in a completely randomized design using 120 one-day-old male broiler chicks of commercial Ross 308 strain to study the effects of three different levels of aspirin (0, 50 and 100 mg/kg) in 3 treatments, in 4 replicates, each including 10 chicks, during 42 days. The effects of different levels of aspirin, added to a basic diet, on performance, carcass characteristics and digestive organs, blood plasma components, liver enzymes, immune system, secal microflora, and acid profile of breast meat of broiler chickens were investigated. Data analysis was performed by SAS statistical software and the comparison of the means with Duncan's multiple-range test at 5% probability level. The results showed that in the final period, the chickens fed by a diet containing 100 mg/kg of aspirin (A) had the highest feed intake and weight gain and the best feed conversion ratio compared to the other treatments. Also, according to the tables, the lowest production cost and the best European factor were related to treatment A100, which was statistically significant compared to the control (P < 0.05). In addition, the use of the same level of aspirin resulted in a significant increase in some carcass properties and a decrease in ventricular fat compared to the control (P < 0.05). On the other hand, the effects of using two different levels of aspirin on blood parameters and liver enzymes of broilers except for alkaline phosphatase were not significant throughout the period (P ≥ 0.05). Also, the use of the same level of aspirin had no significant effect on the function of the humoral immune system in response to antigen injection, antibody titer against sheep red blood cells (SRBC) and antibody titer against Newcastle disease and influenza virus (P ≥ 0.05). But according to the table, the highest percentage of neutrophils and eosinophils was related to this treatment. Also, aspirin treatments increased the levels of unsaturated fatty acids and decreased saturated fatty acids. Moreover, aspirin treatment led to a reduction in the population of Escherichia coli. So, based on the results of the present study, the use of 100 mg/kg aspirin in the diet of broilers is recommended.
