Embodiment Construction

[0011] It has now been found that a diet supplemented with whole algae (eg, Schizochytrium or Nannochloropsis) comprising grass is effective for feeding cattle. This diet allows for the production of grass-fed beef high in omega-3, while addressing two separate consumer needs. It has been found that cattle fed this diet are able to consume more whole algae and thus are comparable to cattle fed using existing methods of increasing omega-3 levels in beef (i.e., fed whole algae under typical feedlot conditions). produce beef products that contain higher levels of omega-3s than cattle). Thus, the application of new grasses and algal diets not only allows the production of grass-fed beef, but the resulting grass-fed beef is superior to existing high omega-3 beef in terms of omega-3 content.

[0012] If the cattle were fed only pasture (which would yield less than about 2% fat on a 17-25 lb dry matter basis), the cattle would be able to consume more algae along with the pasture and...

Abstract

A method for increasing the levels of omega-3 fatty acids ("omega-3s"), particularly docosahexaenoic acid (DHA) and eicosapentaenoic / icosapentaenoic acid (EPA), in beef products by feeding cattle a diet containing grass as the primary ingredient supplemented with whole algae high in omega-3s. A method of increasing the levels of omega-3s in beef comprising feeding beef animals a daily food ration comprising grass and whole algae.

Description

Background technique [0001] Consumer demand for beef products high in omega-3 fatty acids ("omega-3s") is growing. Existing methods for increasing omega-3 levels in beef generally consist of feeding whole algae (eg, Schizochytrium or Nannochloropsis) to cattle under common feedlot conditions. Under these conditions, algae are typically mixed with conventional feedlot ingredients such as grain and harvested forage (eg, corn, wheat, barley, corn gluten feed, wet or dried distillers grains (DDG) and / or chopped hay). [0002] The effectiveness of feeding algae high in polyunsaturated fatty acids (PUFAs), including omega-3s, to cattle depends on several factors: the strength of the outer cell wall of the algae, the acidic environment in the rumen of the animal, the presence of omega-3s in the algae and the amount of omega-3s in the algae relative to the total fat of the diet (ie, algae plus feedlot ingredients). In order to effectively increase the levels of omega-3s in cattle, t...
