Composition Of Goat Meat Research Articles

Meat quality of suckling goat raised in differents feeding systems

The objective of this work was to evaluate the effect of three breeding systems on the organoleptic quality and the physico-chemical composition of kids goat meat. Were used thirty newborn baby goats of 3.35 kg ± 0.65 kg crossed Parda Alpina x Undefined Race (SPRD) submitted to three breeding systems: Traditional system-TS; Intensive Feeding System without Concentrate- IS and Intensive Feeding System with Concentrate- IS+C. When the goats reached 12 kg, the animals were slaughtered and chemical and physical analyzes were performed in the evaluation of the meat and sensorial. The experimental design was completely randomized, submitted to analysis of variance and compared by the Tukey test and Ryan-Einot-Gabriel-Welsh at 5%. All analyzed variables were also submitted to Pearson correlation. The meat of the goats submitted to IS+C and IS presented higher intramuscular fat content and better flavor and aroma scores. A of Goats that used concentrated ration (TS and IS+C) showed a more intense red color in the meat than the animals that did not receive concentrate in their diets, besides presenting higher lipid contents in their composition, better scores for these two organoleptic characteristics. The chemical composition of goat meat in both breeding systems indicates that it is low in fat and high in moisture and therefore classified as very tender and juicy. The meat obtained from the IS+C, in general, presented better attributes than the others, believing it in the markets of meat of high quality.

Growth of Pre-ruminant Kid Goats and the Composition of Carcass Fat Deposits: Effects of Providing a PUFA-rich Fat in the Milk Replacer and Influence of the Kidding Season

The aim of this study is to investigate the possibility of improving the composition of goat meat in terms overall, of the fatty acid composition of different fat deposits. The experiment is designed in an 2 × 2 factorial arrangement. The treatments consist of two different milk replacers, one including and one excluding 2% of fish oil, and two different kidding seasons (spring or autumn). Twelve animals are allocated at random, to each treatment. Animals are slaughtered when they reached a body weight of 7000 ± 200 g. The inclusion of fish oil has no significant effect on growth rate, food efficiency ratio or dressing percentage. The cover, intermuscular and intramuscular fat of the leg from the animals fed with the milk replacer including fish oil, present higher and lower proportions of n-3 PUFA and saturated fatty acids respectively, while that of n-6 PUFA remains unchanged. The inclusion of fish oil in the milk replacer increases the 20 : 5 content in the leg muscle from about 0.4 to 3.5% and 22: 6 content from 0.4 to 2.3%. The fatty acids 20: 5 and 22: 6 are also detected in the cover and intermuscular fat when fish oil is included in the diet. The kid goats born in autumn, show a higher birth weight and growth rate. The leg obtained from these animals, presents a higher proportion of muscle and a lower proportion of bone. However, in the animals born in spring, a somewhat more favourable composition is obtained in the leg fat deposits. The improvement in the quality of meat obtained is discussed, taking into account the feeding strategy provided and the class of animals in question.
