Abstract

The aim of research was to evaluate the meat quality of Nellore young bulls in grazing supplemented with or without addition of lipids. Twenty–four young bulls, 301 ± 5.8 kg in body weight, were used in the experiment and randomly distributed into four groups according to treatment: only Panicum maximum cv. Mombasa grass; Mombasa grass with concentrated supplementation based on soybean meal; Mombasa grass with concentrate containing lipids from soybean oil; and Mombasa grass with concentrate containing lipids derived from soybean grains. There were no differences (P>0.05) between the treatments for temperature, pH, thawing, cooking and total losses, shear force, sarcomere length and collagen in bulls. Nellore young bulls raised in fertilized and irrigated Mombasa grass fed Mombasa grass only or supplemented with or without addition of lipids were similar regarding meat quality.

Highlights

The Brazilian beef industry is specialized in raising grass-fed cattle, due to variations in the quantity and quality of forage offered, the performance of the animals can be compromised (SANTANA et al, 2017)
As lipid supplementation can positively impact meat quality, such forms of supplementation have been the focus of study, as the requirements imposed for the physicochemical characteristics of meat for consumer markets have increased steadily
It was hypothesized that Nellore bulls supplemented with the addition of lipids, regardless of source, could exhibit improved meat quality of young Nellore bulls in grazing

Summary

Introduction

The Brazilian beef industry is specialized in raising grass-fed cattle, due to variations in the quantity and quality of forage offered, the performance of the animals can be compromised (SANTANA et al, 2017). Supplementation of grazing cattle is a common practice used to improve performance as well as the quality of the meat produced (CARVALHO et al, 2017). Among the various types of supplements available, lipid supplements have stood out, since they increase the energy density of the diets and improve the quality of the meat of the cattle (FIORENTINI et al, 2015), increasing tenderness and juiciness of the product (PHOEMCHALARD; URIYAPONGSON, 2015). As lipid supplementation can positively impact meat quality, such forms of supplementation have been the focus of study, as the requirements imposed for the physicochemical characteristics of meat for consumer markets have increased steadily. It was hypothesized that Nellore bulls supplemented with the addition of lipids, regardless of source, could exhibit improved meat quality of young Nellore bulls in grazing. This study aimed to evaluate the effect of supplementation with or without the addition of lipids in the feed of Nellore bulls on physicochemical characteristics of meat
