When addressing mycotoxin issues the fact that multiple ingredients make up a dairy cattle diet can be viewed both positively and negatively. Multiple feeds dilute the toxins from any given feed, resulting in a safer diet. On the other hand, since the effect of toxins can be additive, if there are multiple contaminated feeds, toxicity of individual feeds will be compounded. This article addresses ...

BackgroundCarinata (Brassica carinata) is a new oilseed that shows great potential for the Midwest. This oilseed has been selectively bred for high oil concentration ideal for biofuels and bio-oil production. Carinata meal is the co-product resulting from the oil extraction of the seeds. This meal has high protein content (36-48% crude protein), highly degradable in the rumen, and with a total dig ...

IntroductionThermostasis is the process by which cows attempt to keep their body temperature constant in spite of changes in environmental temperatures. Heat stress occurs when the cow is incapable of dissipating enough heat to maintain its core body temperature below 101.3°F. This increase in body temperature results from the combination of heat from the environment and that produced internal ...

Rumen acidosis results from an excessive acid load in the rumen not neutralized by salivary or feed buffers. Changes in physiology, metabolism, and behavior of heat-stressed cows increase their susceptibility to both sub-acute (SARA) and acute acidosis. Mishra et al. (1970) observed lower rumen pH when cows were fed 65% forage diets under warm, humid conditions (pH 6.1; 84.9F; 85% RH) compared to ...

Productivity and longevity of dairy cows are greatly influenced by proper nutrition programs. Human-animal interaction in larger dairies is limited, and ailments detection relies heavily on employees. Metabolic disorders and their complications such as hypocalcaemia, fatty liver, ketosis, displaced abomasum, acidosis, and laminitis may result from dietary inadequacies. Early veterinary attention i ...

Hormones are normal constituents of milk that are a continuous topic of debate. Hormones are usually peptides or steroids produced in one tissue, transported by blood, to cause another target tissue or organ to modify growth, metabolism, or reproduction. Hormones are essential for growth in humans and animals and can be transferred in small amounts from the blood into milk. Table 1 below defines m ...
