In order to analyze the characteristics of fatty acids in lamb meat in different feeding regimes, the researchers conducted an experiment with thirty Suffolk lambs fed grazing on perennial ryegrass (Lolium perene<\/em>) and supplemented with ryegrass (RGH), or formulated concentrates with fish meal (FSM) or soybean meal (SBM). The results show that there is a variation of the content of fatty acids depending on the source of protein used in the feeding of these animals. The highest fatty acid content was found in pasture-fed sheep without supplementation.<\/p>\n

According to researcher Manuel Gonzalez Ronquillo, the importance of the research is to demonstrate that the fatty acid profile of lamb meat can be changed by feeding different sources of protein or unsaturated fats. “If the farmer feeds the animals with pastures, they will have less weight gain compared to animals receiving supplementation. However, the composition of fatty acid in their meat has a higher percentage, “he comments.<\/p>\n

The results of the research show that the fatty acids found in fishmeal and soybean meal supplements are transformed in the rumem of animals due to microbial activity, a process that does not happen with animals fed only with pasture. The study complements other studies carried out by Manuel\u2019 research group on the effects of different sources of fatty acids in sheep and goat milks. “We found that we can change the fatty acid profile in meat and milk, depending on the fatty acid supplementation the animal receives,” says the researcher.<\/p>\n

Researchers at the Universidad Aut\u00f3noma del Estado de M\u00e9xico<\/i> in Toluca, Mexico, have shown that fatty acid content is higher in lambs fed with pasture compared to animals whose nutrition is supplemented with fishmeal or soybean meal.
