Blood biochemical parameters of broilers fed differently thermal processed soybean meal

Abstract

Objective. A 42-days feeding trial was carried out to evaluate the influences of differently thermal processed soybean meal on the broilers blood biochemical parameters. Materials and methods. A total of 200 male birds of Ross strain were allocated into five different diets formulated using differently heat-treated soybean meals, with ten birds per treatment and per replicate. Diets contained: raw soybean (controls), autoclaved for a short (121°C, 20 min; Aut1 group) or medium length period (121°C, 30 min; Aut2 group) soybean meal, micro-waved soybean meal (46°C, 540 Watt, 7 min; McW group) and browned soybean meal (120°C, 20 min; Brn group). Results. Blood serum metabolites showed that all treated diets presented lower lipid metabolism makers and higher protein metabolism markers. Broilers showed increased final body weight when fed heat-treated meals compared with control. Results suggested that thermal treatments altered the lipid metabolism in broilers that might originate a decrease in abdominal fat deposition. Conclusions. Comparison of the results for all the treated groups showed the Aut2 treatment is the most suitable method for soybean thermal treatment processing; in contrast, the Aut1 treatment had the closest results to the control group.

Effect of Antibiotic, Phytobiotic and Probiotic Supplementation on Growth, Blood Indices and Intestine Health in Broiler Chicks Challenged with Clostridium perfringens

“…Glucose is an important cellular source of energy and serves as a metabolic substrate [74]. The chicks that were administered probiotic-supplemented diets showed a significant increase (p ≤ 0.05) in their glucose levels and decreased ALT concentrations compared to the chicks in the positive control group.…”

Effect of partial replacement of soybean and corn with raw or processed chickpea

“…It was concluded that the autoclaving process reduced the MUFA content of the egg yolk compared with raw chickpeas, and microwaving elevated it. In contrast, observed blood serum metabolites indicated reduced lipid metabolism by birds fed heat-treated soybean meal (Nahavandinejad et al, 2014).…”

“…Various practices are carried out to remove or reduce the harmful effects of anti-nutritional factors when using legume grains in animal feeds. The goal of thermal processing of grain legumes for poultry nutrition is to increase the nutritional value of the feed and maximize bird performance (Nahavandinejad et al, 2014). These include removing the grain chaff, breaking the integrity of the grain (grinding, crushing), heating (dry heat roasting, cooking in water, steaming), treating with water and various chemical substances, and fermenting (Kaya & Yalcin, 1999).…”

Summer Savory (Satureja hortensis L.) Extract as Natural Feed Additive in Broilers: Effects on Growth, Plasma Constituents, Immune Response, and Ileal Microflora

“…Parameters determined were as follows: glucose, triglycerides, uric acid, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), HDL to LDL ratio, and alkaline phosphatase. Blood traits were determined based on standard protocols using commercial kits as reported in Nahavandinejad et al [13].…”
