Systems and methods provide sugar alcohol to heat stressed ruminants to improve performance. During periods of high temperature or humidity, heat stressed ruminants may exhibit decreased dry matter intake, and in response, an effective amount of sugar alcohol such as sorbitol may be provided in the ruminant diet to cause performance to increase, which may include increased milk yield, improved feed efficiency or both compared to heat stressed dairy cattle without sugar alcohol in the diet.

1. A method of feeding a lactating ruminant, the method comprising: during a period of ambient temperature conditions of at least 70° F., determining the lactating ruminant is experiencing heat stress by observing two or more of an about 10 percent decrease in dry matter intake, reduced milk product
1. A method of feeding a lactating ruminant, the method comprising: during a period of ambient temperature conditions of at least 70° F., determining the lactating ruminant is experiencing heat stress by observing two or more of an about 10 percent decrease in dry matter intake, reduced milk production, increased respirations, elevated internal body temperature, open mouth breathing, increased panting, sweating, or failed reproduction; andfeeding the heat stressed lactating ruminant a daily feed ration comprising an amount of sugar alcohol effective to improve a milk-to-feed ratio,wherein the sugar alcohol comprises at least one of sorbitol, xylitol, adonitol, allitol, altritol, arabitol, dulcitol, erythritol, galactitol, glucitol, iditol, inositol, isomalt, lactitol, maltitol, mannitol, perseitol, ribitol, rhamnitol or threitol. 2. The method of claim 1, wherein the sugar alcohol is sorbitol. 3. The method of claim 1, wherein the lactating ruminant is in a post-peak phase of lactation. 4. The method of claim 1, further comprising one or more of: cooling an environment in which the heat stressed lactating ruminant resides; orcooling the heat stressed lactating ruminant using an evaporative cooling method on the ruminant. 5. The method of claim 1, wherein the amount of sugar alcohol is further effective to increase milk yield, increase production of energy corrected milk or increase production of fat corrected milk. 6. A method of feeding a lactating ruminant, the method comprising: during a period of ambient temperature conditions of at least 70° F., determining the lactating ruminant is experiencing heat stress by observing two or more of an about 10 percent decrease in dry matter intake, reduced milk production, increased respirations, elevated internal body temperature, open mouth breathing, increased panting, sweating, or failed reproduction; andfeeding the heat stressed lactating ruminant a daily feed ration comprising an amount of sugar alcohol effective to improve milk production without increasing dry matter intake,wherein the sugar alcohol comprises at least one of sorbitol, xylitol, adonitol, allitol, altritol, arabitol, dulcitol, erythritol, galactitol, glucitol, iditol, inositol, isomalt, lactitol, maltitol, mannitol, perseitol, ribitol, rhamnitol or threitol. 7. The method of claim 6, wherein the improved milk production comprises one or more of increased milk yield, increased production of energy corrected milk or increased production of fat-corrected milk. 8. The method of claim 6, wherein the sugar alcohol is sorbitol. 9. The method of claim 6, wherein the lactating ruminant is in a post-peak phase of lactation. 10. The method of claim 6, further comprising one or more of: cooling an environment in which the heat stressed lactating ruminant resides; orcooling the heat stressed lactating ruminant using an evaporative cooling method on the ruminant. 11. A method of feeding sugar alcohol to a transition ruminant, the method comprising: during a period where ambient temperature conditions are at least 70° F., determining the transition ruminant is experiencing heat stress while the transition ruminant is pregnant by observing one or more of an about 10 percent decrease in dry matter intake or increased respirations; andfeeding the heat stressed transition ruminant a daily feed ration comprising an amount of sugar alcohol effective to reduce beta hydroxyl butyrate levels in the transition ruminant during at least a portion of the transition phase;wherein the transition phase is defined by a period during which the ruminant is pregnant and extending through calving by the ruminant, andwherein the sugar alcohol comprises at least one of sorbitol, xylitol, adonitol, allitol, altritol, arabitol, dulcitol, erythritol, galactitol, glucitol, iditol, inositol, isomalt, lactitol, maltitol, mannitol, perseitol, ribitol, rhamnitol or threitol. 12. The method of claim 11, wherein the sugar alcohol is sorbitol. 13. The method of claim 11, further comprising one or more of: cooling an environment in which the heat stressed transition ruminant resides; orcooling the heat stressed transition ruminant using an evaporative cooling method on the ruminant. 14. The method of claim 1, wherein the sugar alcohol comprises at least sorbitol. 15. The method of claim 6, wherein the sugar alcohol comprises at least sorbitol. 16. The method of claim 11, wherein the sugar alcohol comprises at least sorbitol.
