Elevated Plasma

The aim of this study was to determine if total plasma homocysteine (HCY) concentrations and mortality rates due to ascites syndrome and (AS) sudden death syndrome (SDS) in broiler chickens could be lowered by diet. Elevated plasma HCY is an independent risk factor for cardiovascular disease in humans. A total of 828 day-old male broiler chickens (Arbor Acre) were fed, for 6 wk, either a basal practical diet or one supplemented with excess vitamins B6 and B12, folic acid and betaine to stimulate the degradation of HCY. The supplemented diet decreased plasma HCY by 17% (P < 0.05; n = 16 per diet). Total mortality due to AS and SDS was 18% lower in the supplemented diet but this difference was not statistically significant.

AbstractSudden death syndrome (SDS) is an economically important disorder in broiler chickens with unknown aetiology. The aim of the present study was to evaluate the metabolic and molecular alterations related to hypoxia in the myocardium of broiler chickens with SDS. Samples from the cardiac muscle of internal control broiler chickens (ICs) (n = 36) and chickens having died of SDS (n = 36) were obtained during the rearing period. The activities of lactate dehydrogenase (LDH) and creatine phosphokinase (CPK) and the concentration of lactate were measured in the cardiac tissue using available commercial kits. The expression of hypoxia-inducing factor 1α (HIF1α), glucose transporter 1 (GLUT1), pyruvate dehydrogenase kinase 4 (PDHK4) and monocarboxylate transporter 4 (MCT4) genes was determined in the myocardium by real-time PCR analysis. The results showed the elevation of lactate level and activities of LDH and CPK in the cardiac muscle of SDS-affected chickens compared with the IC birds (P < 0.05). The cardiac muscle expression of HIF1α, MCT4 and GLUT1 genes was increased, while the PDHK4 mRNA level was decreased in the SDS-affected group compared to those in the IC chickens (P < 0.05). Our results showed that metabolic remodelling associated with hypoxia in the cardiac tissues may have an important role in the pathogenesis of cardiac insufficiency and SDS in broiler chickens.

Protein Components

Three experiments involving 11 600 male broiler chickens sought to determine if the pelleting process affects the dietary micronutrient, fat and protein components to increase the incidence of sudden death syndrome. Processed dietary micronutrient and fat components were not significantly associated with an increase in sudden death syndrome among broiler chickens. In one of the experiments, the incidence of sudden death syndrome was reduced (P < 0.01) when the dietary protein supplements (soybean meal, canola meal and fishmeal) bypassed the pelleting process.

Overall Mortality

A total of 2400 broiler chickens were used in four experiments to estimate the effects of using 0.04, 0.08 and 0.16% aspirin (ASA) as dietary supplements. Not only did the ASA dietary supplementation have no significant (P < 0.05) beneficial effect on the incidence of sudden death syndrome but it also had a deleterious effect on overall mortality which was significant (P < 0.01) in two of the four experiments. Furthermore, the addition of ASA at 0.16% to the diet resulted in reduced body weights which were significant at P < 0.05 in two experiments and at P < 0.10 in the other two experiments.
