“…In this study, a high level of NH 3 decreased the serum globulin concentration on the third week, which is partly in agreement with the results of previous research (Javed et al, 1995;Stanley et al, 2004;Gao et al, 2009;Andretta et al, 2012;Li et al, 2012). Moreover, in this study, NH 3 and RH had an additive detrimental effect on albumin, total protein, and globulin.…”

ABSTRACT.To investigate the effect of ammonia (NH 3 ) and humidity on the immune response of broilers, broilers were exposed to 30 or 70 mg/kg atmospheric NH 3 for 21 days. Additionally, birds were exposed to 35, 60, and 85% relative humidity (RH). The relative weights of lymphoid organs, serum total protein, serum globulin, serum albumin, serum lysozyme, proliferation index of peripheral blood lymphocytes, and splenic cytokine gene expression were determined. Exposure to 70 mg/kg NH 3 decreased the relative weight of the spleen during the experimental period, serum lysozyme concentration in the first and second weeks, and serum globulin concentration in the third week. The proliferation of peripheral blood lymphocytes was reduced. High levels of NH 3 caused increase in IL-1β gene expression in the experimental period and IL-4 gene expression in the first week. Birds exposed to 85% RH had lower thymus and bursa of Fabricius weights in the third week and serum lysozyme concentration in the first week; IL-1β and IL-4 expressions were higher in the second and third weeks and first and second weeks, respectively, than in birds exposed to 60% RH. IL-4 expression was lower during the first week, and IL-1β expression was higher during the second week with 35% RH than with 60% RH. In conclusion, high NH 3 level in the poultry house suppressed the immune response of broiler chickens. Neither high nor low RH benefited the immune response of broilers. Furthermore, there was an interactive effect between NH 3 and RH on the immune response of broilers.

“…Under stress conditions, YC was reported to have a beneficial effect on broiler performance when birds were challenged with Eimeria spp. (Stanley et al, 2004a) or aflatoxin (Stanley et al, 2004b). The response to antimicrobial agents was greater in a "dirty" environment (Cromwell, 2000).…”

Effects of Yeast Culture in Broiler Diets on Performance and Immunomodulatory Functions

et al. 2008

A study was conducted to evaluate the effect of supplemental yeast culture (Diamond V XP Yeast Culture; YC) in broiler diets on performance, digestibility, mucosal development, and immunomodulatory functions. One-day-old Arbor Acres chicks (n = 960) were randomly assigned to 1 of 4 dietary treatments based on corn and soybean meal and containing 0, 2.5, 5.0, and 7.5 g/kg of YC in the diet for 42 d. Each treatment consisted of 12 replicates of 20 broilers each. Nutrient digestibility was determined on d 15 and 35 by total fecal collection. On d 21 and 42, 12 birds per treatment were sacrificed to evaluate gut morphology and secretory IgA. Broilers were vaccinated with Newcastle disease vaccine by eye drop on d 7 and 28 and antibody titer was determined on d 14, 21, 35, and 42. Dietary supplemental YC at 2.5 g/kg improved average daily gain and feed conversion during grower and overall periods (P 0.05) protein retention and energy digestibility. Villus height to crypt depth ratios in the duodenum and jejunum (d 42) and ileum (d 21) were increased (P

“…Brake et al (2000) reported that there were dose-related decreases in body weight and feed consumption indicating feed refusal, as well as dose-related increases in the extent of mouth lesions of broiler breeders fed with 0.00, 5.00, 10.00, or 20.00mg DAS/kg diet from 24 to 25 wk of age. Stanley et al (2004) reported that feeding aflatoxin at the rate of 3mg/kg to 35 week's old Cobb broiler breeder hens for three weeks significantly reduced serum total protein, albumin, calcium and phosphorus levels. Sypecka et al (2004), reported that only trace amounts of Fusarium mycotoxins are transferred into the eggs of laying hens, which are unlikely to be of significance with respect to embryonic mortality.…”
