The nutritional quality of chuck and shank meat of thin-tailed sheep supplemented with protected aldehyde in the rations

Abstract

The purpose of this study was to determine the effect of aldehyde supplementation, protected and without protection on the nutritional quality of chuck and shank meat of thintailed sheep. Thin tailed sheep were fattened for 3 months with 30% forage and 70% concentrate. The chuck and shank meat were obtained via carcass preparation by AMLC method. Meat samples taken from the right carcass pieces and tested for nutritional quality including moisture content, protein content, fat content and cholesterol. Feed treatments were P0 = 30% elephant grass + 70% basal concentrate; P1 = 30% elephant grass + 60% basal concentrate + 10% soybean groats without formaldehyde protected; and P2 = 30% elephant grass + 60% basal concentrate + 10% soybean groats without formaldehyde unprotected. The difference in feed treatment significantly affected the cholesterol levels of chuck and shank meat (P <0.05) and protein content of chuck meat (P <0.05). The conclusion was that chuck and shank meat of thin-tailed sheep contained lower cholesterol in thin-tailed sheep which was given protected and non-protective supplement than control. The thin-tailed sheep which were supplemented with protected and without protection containing higher protein than control.
