“…Lymphoid tissues play an important role in the body defence against microorganisms. The bursa and spleen are sites of B cells and T cells differentiation, respectively (Fasina et al 2006). The relative lymphoid organs weight is used to investigate the immune status of birds and changes in weight may be associated to alterations in the function of lymphoid organs (Cooper et al 1966).…”

The objective of this experiment was to evaluate the effect of bee glue (BG) on the performance, relative visceral weights, some blood parameters, and immune status of broilers. A total of 200 male Ross 308 broiler chicks were randomly assigned to 5 dietary treatments: basal diet (BD), and basal diet supplemented with 600, 700, 800, and 900 mg kg −1 of BG. Each of the 5 diets was fed to 4 replicates of 10 chicks each from 0 to 42 days of age. The results indicated that the highest body weight, average daily gain, average daily feed intake, carcass weight, and carcass yield were observed in broilers offered 800 mg kg −1 of BG (P < .05). Inclusion of BG improved the feed conversion ratio compared with the control group (P < .01). The calculated European broiler index and crop percentage were greater for the birds received 800 and 900 mg kg −1 of BG compared with that of the control birds (P < .05). Inclusion of 900 mg kg −1 of BG significantly increased the relative weight of spleen and bursa, but reduced total triglycerides, cholesterol, LDL, and LDL: HDL ratio than the control group (P < .05). The serum IgG and IgM levels were increased for the birds received 700 to 900 mg kg −1 BG (P < .01), and addition of BG to the basal diet significantly increased antibody response against sheep red blood cell at 35 days of age (P < .05). It was concluded that an addition of 800 mg kg −1 BG to diet improves economic efficiency possibly by creating miniscule improvement in FCR and promoting immune response of broilers. ARTICLE HISTORY

“…Structure of small intestine plays a vital role in nutrient digestion and absorption (Lenhardt and Mozes, 2003); however, manipulation in the feed may alter villus height to crypt depth ratio, and absorptive area of intestine (Fasina et al, 2006). Moreover, the supplementation of phenolic compounds, like curcumin, may decrease gut inflammation, increase nutrients digestibility and metabolic activity (de Beer et al, 2008;Buchanan et al, 2008;Giannenas et al, 2010).…”

The objective of this study was to determine the appropriate concentration of dietary supplementation of curcumin, and its effect on growth performance, intestinal morphology, fat metabolism and nutrients utilization of broiler chicks. Four hundred eighty, 1-day-old Arbor Acre broiler chicks were allocated into four groups with 6 replicates of 20 birds per cage. Birds were fed a corn-soybean basal diet supplemented with curcumin at 0 (control, CRM0), 100 (CRM100), 150 (CRM150) and 200 mg/kg (CRM200) levels for 42 days. All birds were kept in wire floor triple deck battery cages under semi-intensive housing management. The results revealed that dietary supplementation of curcumin at 200 mg/kg significantly improved live body weight and feed efficiency at marketing age (42 d); while, there was no significant difference on feed intake as compared to control. Curcumin significantly improved utilization of apparent metabolizable energy and decreased abdominal fat at 42 d in CRM150 and CRM200 broilers, respectively. Plasma T4 hormone level and fat utilization were significantly increased; while plasma cholesterol level was significantly reduced in dose dependent manner for CRM200 broilers. The results showed that dietary supplementation of curcumin influenced the histomorphological measurements of small intestinal villi. The villus height was significantly increased in duodenum, jejunum and ileum in curcumin supplemented broilers. Villus width was also significantly increased in duodenum and jejunum (42 d). While, there was no significant difference in ileum villus width. Furthermore, villus height to crypt depth ratio was significantly increased in all segments (except jejunum 42 d) of small intestine in CRM200 group; however, the intestinal crypt depth was lowered in curcumin supplemented broilers. In conclusion, supplementation of curcumin at 200 mg/kg feed enhanced the growth performance and fat metabolism, and increased villus absorptive area of small intestine, resulting in improved nutrients absorption in CRM200 group.

“…The relative weight of lymphoid organs is often used to predict the immune status of an animal ( Abdel-Fattah et al, 2008 ); changes in weight may be related to alterations in the lymphoid organs’ function, and could result in an increased susceptibility to infections or a reduction in the ability of the animal to maintain productivity during a sanitary challenge ( Fasina et al, 2006 ). According to Fan et al (2013) propolis is able to enhance lymphocyte proliferation, and this can reflect in the lymphoid organs weight, impacting on immune function and disease resistance ability.…”

This study was conducted to evaluate the effect of inclusion of propolis extraction residue in the feed of broilers from 1 to 21 d of age on phagocytic activity of macrophages, cutaneous basophil hypersensitivity response to phytohemagglutinin, antibody production against Newcastle disease, lymphoid organ weight and hematological profile and to determine the optimal level of inclusion. 120 chicks, reared in metabolism cages until 21 days of age, were distributed in a completely randomized design, with five treatments (0%, 1%, 2%, 3%, and 4% of propolis residue) and six replications. The relative weight of thymus and monocyte percentage were affected by propolis residue, with a quadratic response (p<0.05) and lowest values estimated at 2.38% and 2.49%, respectively. Changes in relative weight of cloacal bursa and spleen, percentage of lymphocyte, heterophil, basophil, eosinophil, and heterophil:lymphocyte ratio, antibody production against Newcastle disease, phagocytic activity of macrophages and the average number of phagocytosed erythrocytes were not observed. The nitric oxide production with regard to positive control (macrophages+erythrocytes) decreased linearly (p<0.05) with increased doses of propolis residue. The remaining variables of nitric oxide production (negative control – macrophages, and difference between the controls) were not affected by propolis residue. The cutaneous basophil hypersensitivity response to phytohemagglutinin as determined by the increase in interdigital skin thickness exhibited a quadratic response (p<0.05), which predicted a lower reaction response at a dose of 2.60% of propolis residue and highest reaction response after 43.05 hours of phytohemagglutinin injection. The inclusion of 1% to 4% of propolis extraction residue in broiler diets from 1 to 21 days of age was not able to improve the immune parameters, despite the modest changes in the relative weight in thymus, blood monocyte percentage, nitric oxide concentration, and interdigital reaction to phytohemagglutinin.
