• a “ruminant” is generally a suborder of mammal with a multiple chamber stomach that gives the animal the ability to digest cellulose-based food by softening it within a first chamber (rumen) of the stomach and to regurgitate the semi-digested mass to be chewed again by the ruminant for digestion in one or more other chambers of the stomach.
• ruminants include, but are not limited to, lactating animals such as cattle, goats and sheep.
• Cattle may include dairy cows, which are generally animals of the species Bos taurus. The milk produced by ruminants is widely used in a variety of dairy-based products.
• the present disclosure generally relates to fatty acid compositions, ruminant feed mixtures, the dietary compositions made therefrom, and to the methods for making the dietary compositions that can be fed to ruminants.
• the dietary compositions may be configured to improve various aspects of milk production in the ruminants. For instance, some embodiments provide that the dietary compositions may increase the amount of milk production by the ruminant, increase the fat content of the milk produced by the ruminant, increase the protein content of the milk produced by the ruminant, or all three.
• Specific compositions described herein may include ruminant feed mixtures, supplements, or the like.
• the dietary compositions may include liquids, solids or combinations thereof, such as dry particles, pellets, liquid suspensions, emulsions, slurries, pastes, gels, or the like.
• the nutrients such as fat, amino acids, and vitamins etc. in the feed may be degraded or modified by the rumen microbes. This may cause several potential undesirable effects: first, nutrients that are not inert in the rumen may not reach the lower digestive tract and therefore become unavailable to the ruminant; second, the nutrients that are not inert in the rumen may have a negative effect on rumen digestion and health and therefore may decrease feed intake and decrease rumen digestibility of the feed; and, third, the metabolite from the rumen metabolism of some nutrients may negatively affect milk production.
• feeding of vegetable oils can have negative effects on both rumen function and milk formation.
• the ruminal microbes may convert unsaturated fats to saturated fats in a sequence of events called biohydrogenation. It has been hypothesized that this act of biohydrogenation by bacteria is an attempt to protect themselves, as unsaturated fats can be toxic to bacteria, primarily the bacteria that digest fiber. If the feeding of unsaturated fats reduces the numbers or activity of fiber-digesting bacteria in the rumen, then feed intake may decrease, milk production may decrease, and milk fat concentration may decrease.
• trans fatty acids such as the trans- 10, cis-12 conjugated linoleic acid (CLA) and the trans-10 C18: l .
• CLA cis-12 conjugated linoleic acid
• trans-10 C18: l trans-10 C18
• trans fatty acids may negatively impact milk fat synthesis when they leave the rumen, are absorbed into the blood stream, and are taken up by the mammary gland.
• the milk fat concentration may decrease, and the proportion of trans fatty acids may increase.
• a typical fatty acid composition of milk fat may contain more than about 70% saturated fatty acids and a total amount of trans fatty acids may be from about 3% to about 10%. When vegetable oil is added into the feed, the proportion of trans fatty acids may rise to more than about 10%.
• Fat biohydrogenation can be decreased, for example, by protecting fats from rumen bacteria with formaldehyde-treated casein.
• Another alternative is to feed the ruminant insoluble fatty acid calcium salts whereby hydrogenation in the rumen can be reduced.
• fatty acid salts typically have a pungent taste that may result in decreased feed intake by the ruminant.
• the salts may also disturb certain processes for forming the feed into pellets.
• a rumen by-pass composition may allow for the transfer of a nutritional agent from via the digestive tract into the blood circulation of a ruminant. This may improve the energy efficiency of milk production and the utilization of energy by the ruminant. When the utilization of energy becomes more effective, milk production, milk solids production, the concentrations of milk protein, the concentration of milk fat, or all of the above may rise.
• the dietary composition may be configured to enhance fat synthesis in the mammary gland by bringing milk fat components to the cell such that energy consuming synthesis in the mammary gland is not necessary. As a result, glucose may be used more efficiently for lactose production causing increased milk production.
• the milk protein content may increase because there is no need to produce glucose from amino acids. Accordingly, the ruminant may not lose weight at the beginning of the lactation period, thereby improving the fertility of the ruminant.
• the application provides rumen by-pass compositions.
• the application provides a rumen by-pass composition, comprising a first rumen by-pass component and a nutritional composition, wherein the first rumen by-pass component comprises a first fatty acid composition having a melting point not less than 40°C and an Iodine Value not greater than 30.
