Effect of pomegranate-residue supplement in neonatal calves

Cryptosporidium parvum is considered one of the most common enteropathogens, responsible for the high incidence of diarrhea and deleterious implications on immunity and health in neonatal calves. FULL STORY »

No adverse effects of GE feeds in livestock diets

An article published in the peer-reviewed Journal of Animal Science concludes feeding livestock diets that contain genetically engineered (GE) crops has no impact on the health or productivity of those animals. FULL STORY »

Statistical filtering improves feed composition database accuracy

Dairy ration formulation models assume the nutrient composition of individual ingredients is known with certainty, and that the dietary concentration of a nutrient equals the weighted average of the nutrients provided by each ingredient. Both assumptions are invalid to varying degrees. FULL STORY »

Corn bran vs. corn grain at two forage levels

The objective of this study was to determine the effect of substituting corn bran (CB) for dried ground corn grain (CG) in the nonforage portion of high-forage (HF) and low-forage (LF) diets. Twelve multiparous and 12 primiparous Holsteins were assigned to four diets. The effects of these treatments on performance, intake, and apparent total-tract digestibility of the diets were evaluated. FULL STORY »

Low-starch, low-forage diets can support normal rumen function

Many factors, including ethanol production, have led to lower starch rations using more non-forage fiber sources. We know that lower starch does not generally lead to problems in the rumen, but the combination of low starch and lower forage has been relatively unexplored. This trial looked at the effect of feeding a lower-starch diet with different amounts of forage. FULL STORY »

Effects of PMRs on rumen and milk production

With the increase of robot milking systems, this study may lend some insight as to feeding strategies that may be most effective for stabilizing rumen environment. FULL STORY »

Viseral fat concentration not captured through BCS

Relatively little is known about changes in mass or function of internal fat deposits in dairy cows, particularly during the periparturient period. FULL STORY »

Accurate tools for cow-side measurement of BHBA concentrations

Hyperketonemia is defined as an abnormally high concentration of circulating ketone and is an indicator of excessive negative energy balance in transition dairy cows. The gold standard for diagnosing hyperketonemia is the measurement of BHBA in serum or plasma. Implementing a hyperketonemia surveillance program using DHI monthly milk test data could be a practical approach. FULL STORY »

Melatonin feeding compared to long day lighting

In lactating dairy cows, exposure to a long-day photoperiod is associated consistently with an increase in prolactin concentration and milk production. FULL STORY »

Relationships: Fertility and postpartum changes in BCS, weight

The relationship between energy status and fertility in dairy cattle was retrospectively analyzed by comparing fertility with body condition score (BCS) near artificial insemination (AI); early postpartum changes in BCS; and postpartum changes in body weight (BW). FULL STORY »

Rumination time around calving to detect disease risk

The main objective of this experiment was to evaluate the use of rumination time (RT) during the peripartum period as a tool for early disease detection. The study was carried out in an experimental freestall barn and involved 23 Italian Friesian cows (9 primiparous and 14 multiparous). FULL STORY »
