Problems solved by technology

Although effective, ethoxyquin is generally more effective as an antioxidant in fish oils and animal fats and less effective in controlling oxidation in plant-derived oils
Furthermore, dietary antioxidants are generally only used to control oxidation during storage of fat sources and not after fat sources have been fed to ruminants

Embodiment 1

[0109] Example 1 Efficacy of Antioxidant Blends and Individual Antioxidants in Stabilizing Oils or Fats

[0110] The aim of the study was to compare the efficacy of a blend of ethoxyquin (ETX) and tert-butylhydroquinone (TBHQ) with ETX alone or TBHQ alone in preventing oxidation of soybean oil, yellow grease, and wet distiller's grain. ETX and TBHQ combined under the trade name AGRADO PLUS Purchased from (Novas International Inc.; St. Louis, MO). AGRADO PLUS is a blend of 65% ethoxyquin, 7% t-butyl hydroquinone, 7% citric acid, 19% propylene glycol, and 2% corn oil. ETX products under the trade name AGRADO and SANTOQUIN Purchased from (Novas International Inc.; St. Louis, MO).

[0111] method The stability of lipid materials was assessed using the Active Oxygen Method (AOM) and / or Oil Stability Index (OSI) method. The AOM measures oil or fat stability by bubbling air through an oil or fat sample at specified flow rates, temperatures, and concentrations. The temper...

Embodiment 2

[0116] Example 2 The combination of ethoxyquin and tert-butylhydroquinone can stabilize oil and fat used in ruminant diets

[0117] The purpose of this study was to evaluate the ability of the combination of ethoxyquin and TBHQ to stabilize non-inert oils and fats used in cattle diets.

[0118] method. The degree of oxidation and fatty acid profiles of five different edible oils or fat sources were determined before and after artificial oxidative stress. The oils or fats are: corn oil (co), soybean oil (so); herring fish oil (fo); yellow grease (yg); and a blend of corn oil, fish oil and yellow grease (bo). The quality of various oils or fats is determined by the degree of oxidation (initial peroxide value, ipv). The initial peroxide value measures the concentration of peroxide and hydrogen peroxide formed during the initial stages of lipid oxidation. The milliequivalent of peroxide per kilogram of fat (meq / kg) was measured by iodide titration.

Embodiment 3

[0130] The combination of embodiment 3 ethoxyquin and TBHQ can prevent the oxidation of fatty acid in solid feed

[0131] Approximately 50% of the lipids in a cattle diet come from feeds other than supplementary oils and fats. Feeds such as cottonseed, distiller's grains, soybean products or fishmeal contribute significantly to total dietary lipids. Lipids from these components mostly contain high levels of easily oxidized unsaturated fatty acids. For example, distillers grains from the ethanol industry are a very unstable source of unsaturated fatty acids. The heat treatment during distillation and the high water content of wet distiller's grains exacerbate the oxidation process of unsaturated fatty acids. The end result is that the fats in the stillage are highly oxidized and unstable. The aim of the study was to determine the efficacy of the ETX+TBHQ combination to stabilize lipids in wet distillers grains (WDG) or linseed.

Abstract

The present invention provides a combination of antioxidants that effectively stabilize different types of fats utilized in a ruminant diet. When included in a ruminant feed ration or water source, the antioxidant combination typically increases nutrient digestion, such as fiber and protein, improves rumen fermentation, improves microbial growth, improves microbial efficiency, increases milk production and / or milk fat, improves antioxidant status of the ruminant, and attenuates the negative effects of some fats in the ruminant animal.

Description

field of invention [0001] The present invention generally provides a combination of antioxidants for ruminant feed rations. The combination of antioxidants when fed to a ruminant reduces the formation of free radicals in the diet, improves the digestion of nutrients, and optimizes fermentation in the animal's rumen. Additionally, the present invention provides methods of increasing milk production and / or milk fat content, improving the antioxidant status of ruminants, and reducing adverse rumen effects associated with feeding ruminants with non-inert fat sources. Background of the invention [0002] Fat is a concentrated source of energy and its inclusion in feed rations for cattle and other ruminants is standard practice. Fats, however, are susceptible to oxidation, a degradation process (ie, rancidity) that reduces their nutritional value and produces volatile compounds that have an unpleasant odor and taste. The rate of oxidation increases with the degree of unsaturatio...
