“…The increase in jejunal IgA from 1 to 5 d of age may be partly due to the secretion of biliary IgA into the intestinal tract. In previous research, Piquer (1990) and Piquer et al (1991) reported that IgA concentration in bile decreased markedly from 1 to 9 d of age.…”

Two 21-d experiments were conducted to document the effects of an early immunologic stress and changes in dietary ME(n) on selected characteristics of immune function of newly hatched turkeys. Eight treatments were included in each experiment. Treatments were the result of complete factorial arrangements of two types of injection and four isonitrogenous diets. Turkeys in both experiments were injected i.p. with .5, .5, and .2 mL of saline (SAL) or .5, .5, and .2 mL of a solution of Escherichia coli lipopolysaccharide (LPS) (100 micrograms LPS/mL SAL) at 1, 3, and 5 d of age, respectively. In Experiment 1, two diets were formulated to contain 2,800 kcal ME(n)/kg. One was a corn-soybean meal based diet (CSBM) and the other contained 8% Solkafloc (SKF). A third diet (3,100 kcal ME(n)/kg) was formulated by substituting 8% sucrose (SUC) for the 8% SKF. The fourth diet (HE) included in Experiment 1 was formulated to contain 3,700 kcal ME(n)/kg. The CSBM and SUC diets and two additional diets were tested in Experiment 2. The latter were the CSBM diet containing 74.5 mg ibuprofen/kg (IBU) and a corn-soybean meal diet formulated to contain 3,100 kcal ME(n)/kg (CS31). Concentrations of plasma IgG and jejunal IgG and IgA were not affected by injection or diet. Age-related changes in Ig concentrations were consistently observed in Experiments 1 and 2. Injection with LPS reduced the number or responses of blood leukocytes to mitogens at 8 d of age (P < .01), as compared with samples from turkeys injected with SAL. Leukocytes in whole blood samples from turkeys fed the HE diet responded less to LPS stimulation than those fed the SUC diet (P < .01). Injection with LPS did not markedly affect the characteristics of immune function studied, and feeding a diet with 3,100 kcal ME(n)/kg and 28.5% crude protein did not measurably affect the characteristics of immune function of young turkeys.

“…The immune system plays a vital role in the development of the gastrointestinal tract, helping the intestine to act as a barrier between the environment and the body. However, the immune system of poultry is immature at the time of hatching, and this observation has been confirmed by several reports (Jeurissen et al, 1989;Piquer et al, 1991;Schat and Myers, 1991). Piquer et al (1991) observed a very low concentration of immunoglobulin A in intestine of poults until 9 d after hatch, followed by a marked increase until 29 d of age.…”

SUMMAYuring recent years, researchers evaluated many of eco-friendly alternatives to antibiotics such natural bee products as growth promoters in poultry production to improve the productive efficiency, modify the gut microflora, control diseases and enhancing the immune-response. The present study aimed at assessing the impacts of bee venom in drinking water on the growth performance, carcass merits, blood health, and immunity of broilers. Three hundreds and seventy five unsexed one-day old Avian chicks with an initial body weight of (45.2 ± 0.7g), were obtained from a local commercial hatchery. Chicks were kept at a private poultry farm under supervision of Animal Production Department, Faculty of Agriculture, Tanta University. Chicks were divided randomly into five equal experimental groups; each group divided into 3 replicates; each replicate has 25 birds. Control group (C) received drinking water without any supplementation (tap water). Treatment 1, 2, 3 and 4 received drinking water treated with bee venom at the level of (0.5, 1.0, 1.5 and 2.0 mg/Liter), respectively. Results showed that, birds received bee venom at the level of 2.0 mg/L drinking water had significantly (P≤0.05 and 0.01) the highest body weight. Chicks received bee venom at the level of 2.0, 1.5 and 1.0 mg/L. drinking water recorded superior (p≤0.05) weekly body weight gains than those fed 0.5 mg/L and control group. The highest (p≤0.05) amount (3008.9gm) of total feed consumption per bird recorded by the control group compared to (2908.9, 2907.0, 2916.6 or 2916.2) of those received bee venom at the levels of 2.0, 1.5, 1.0 or 0.5 mg/L, respectively. Regarding feed conversion ratio, through the whole experimental period (0 to 5 week), there were no significant differences among treated groups while, it has a significant improvement compared to birds in control group. There were significant (P≤0.05) effects for carcass, dressing, abdominal fat and relative liver, thymus, and spleen weights between broilers received drinking water supplemented with different levels of bee venom and those of the control. No significant differences (P>0.05) were observed for each IgA, IgG, and IgM. It could be concluded that the use of bee venom in drinking water of broilers up to 2mg/L. is able to improve productive performance, carcass traits and some blood biochemical parameters.
