Rice Bran as an Alternative Feedstuff in Broiler Nutrition and Impact of Liposorb® and Vitamin E-Se on Sustainability of Performance, Carcass Traits, Blood Biochemistry, and Antioxidant Indices

Abstract

The impact of dietary rice bran with or without feed additives on the performance, carcasses, and blood profiles of chickens was examined. A total of 245 unsexed one-week-old broiler chicks were divided into seven groups, with seven replications of five chicks each. The treatments were: (1) control, (2) 5% rice bran, (3) 5% rice bran + 0.5 g/kg of Liposorb®, (4) 5% rice bran + 1 g/kg of vitamin E-Se, (5) 10% rice bran, (6) 10% rice bran + 0.5 g/kg Liposorb®, and (7) 10% rice bran + 1 g/kg of vitamin E–selenium. Considering the entire experimental period, it did not affect the in vivo performance of the broilers. However, all the experimental diets decreased dressing % compared with the control (p < 0.01) and the worst values were obtained for the 10% RB groups (75.7, 75.9, and 75.8%, respectively, for 10%RB, 10%RB + Liposorb, and 10%RB + Vit. E-Se groups). All the experimental diets decreased (p < 0.01) the albumin/globulin ratio due to an increased level of serum globulins. Differences in lipid profiles, antioxidants, and immunity parameters in plasma were not related to dietary treatments. In conclusion, the use of rice bran up to 10% in diets had no harmful effect on the overall growth performance of the broilers from 1 to 5 weeks of age. Still, carcass characteristics were negatively affected, except for heart percentage. In addition, the supplementation of Liposorb® or vitamin E-Se to rice bran diets did not recover these harmful effects. Thus, rice bran could be utilized at 10% in broiler diets when growth performance was considered; further research is required.

The Requirements of Chickens for Nutritional Compounds for Growth, An advanced Nutritional outlook

“…It can be used in adult chickens and adult chickens by no more than 10% and increases in ducks, geese and turkeys up to 35%. it is noted that the percentage of phosphorus is not available in it, and the utilization of phosphorus can be improved by adding the enzyme phytase [50].…”

Cereal by-products as alternative energy sources in poultry diets: A review

“…The high levels of unsaturated fats in rice bran make it susceptible to oxidative rancidity; thus, stabilizers such as ethoxyquin are often added to rice-based diets. Raw rice bran contains anti-nutritional factors such as trypsin inhibitors and phytic acid that hinder growth and feed efficiency in poultry (Attia et al, 2023; Leeson & Summers, 2005) [6,23] . The nutritive value of rice bran is improved through fermentation technologies and the use of feed enzymes (Attia et al, 2023) [6] .…”

The Role of Vitamin E as an Antioxidant and Preventing Damage Caused by Free Radicals

“…Tocopherols, which are dominant, are found in high concentrations in wheat germ, corn, cottonseeds, and sunflower seeds [6], [7]. Absorption of vitamin E with fat occurs in the small intestine, but it is concentrated in the duodenum depending on the functions of the pancreas and bile secretions.…”
