THE EFFETS OF BORON (ORTHOBORIC ACID) SUPPLEMENTATION ON MEAT PROTEIN AND LIPID PROFILES OF LAYING HENS

Abstract

Boron is a metalloid element from Group IIIA of the periodic table. The principal uses for boron compounds include industrial purposes. It is believed to be boron an essential nutrient and influences the concentrations or activity of many macromolecules and plays a role in a large number of metabolic events and growth by affecting energy substrate utilization. This study was carried out to determine the effects of boron (orthoboric acid) supplementation into the diets of hens in the late laying period on protein and lipid profiles of meats. Two hundred and eighty eight Lohman commercial laying hens 62 weeks old were fed with 0, 50, 75 and 150 mg/kg of boron for 12 weeks. In the present study boron supplementation up to 150 mg/kg in to the diets did not affect protein concentrations and profiles of meats negatively. However, increased TG, PL percentages, while decreased FFA, DAG and COL percentages in the total lipids.
