Abstract
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.
Claims28
A method of feeding a lactating ruminant sugar alcohol for improving performance during periods of heat stress 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 performance, increased respirations, elevated internal body temperature, open mouth breathing, increased panting, sweating, or failed reproduction;
- and
- feeding the heat stressed lactating ruminant an amount of sugar alcohol effective to improve performance;
- 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;
- and
- wherein the amount of sugar alcohol effective to improve performance is from about 50 grams to about 150 grams of sugar alcohol per ruminant per day.
A method of feeding sugar alcohol to a transition ruminant in a transition phase during periods of heat stress to improve milk production after calving, 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;
- and
- feeding the heat stressed transition ruminant a daily feed ration comprising an amount of sugar alcohol effective to improve milk production after calving;
- 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;
- wherein the amount of sugar alcohol effective to improve performance is from about 50 grams to about 150 grams of sugar alcohol per ruminant per day;
- and
- wherein the transition phase is defined by a period during which the ruminant is pregnant and extending through calving by the ruminant.
A method of feeding a lactating ruminant sugar alcohol for improving performance during periods of heat stress 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 performance, increased respirations, elevated internal body temperature, open mouth breathing, increased panting, sweating, or failed reproduction;
- and
- feeding the heat stressed lactating ruminant an amount of sugar alcohol effective to improve performance, wherein the sugar alcohol comprises sorbitol.
A method of feeding sugar alcohol to a transition ruminant in a transition phase during periods of heat stress to improve milk production after calving, 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;
- and
- feeding the heat stressed transition ruminant a daily feed ration comprising an amount of sugar alcohol effective to improve milk production after calving, wherein the sugar alcohol comprises sorbitol;
- and
- wherein the transition phase is defined by a period during which the ruminant is pregnant and extending through calving by the ruminant.
