Response of lactating cows to live yeast supplementation during summer

Effect of yeast culture supplementation of alfalfa silage or alfalfa hay fed to lactating dairy cows

Effect of live yeast culture supplementation on rumen fermentation in lactating dairy goats

Addition of yeast to dairy cow diets might be beneficial for milk production. However, data concerning goats are scarce, especially on the role of yeast on rumen metabolism. Thus, four goats, according to a cross-over design, received successively two diets with or without living yeasts. Animals were in mid-lactation and received a total mixed diet ad libitum. For the yeast diet (Y), each goat ...

Performance of Lactating Dairy Cows Fed Yeast and Fibrolytic Enzymes

We evaluated the effect of supplementing typical dairy diets with yeast and fibrolytic enzymes on dairy cow performance. Twentyfour Holstein cows were used to evaluate the effects of yeast (Procreatin-7, a live culture of Saccharomyces cerevisiae) and various amounts of FP800 (a fibrolytic enzyme mixture) on lactation performance. Treatments were arranged in a 4 × 2 factorial design consisting ...

Milk Production, Milk Composition, Live Weight Change and Milk Fatty Acid Composition in Lactating Dairy Cows in Response to Whole Linseed Supplementation

The objective of this study was to determine the effects of whole linseed supplementation on performances and milk fatty acid composition of dairy cows. Thirty six Holstein Friesian crossbred lactating dairy cows were blocked by milking days first and then stratified random balanced for milk yields and body weight into three groups of 12 cows each. The control group received 300 g of palm oil. ...

Electrolytes Supplementation through Drinking Water to Revive Broiler Production during Tropical Summer Stresses Management

This experiment was carried out for a period of 4 weeks with 240 day old straight- run broiler (Cobb-500) chicks to investigate the effects of administering electrolytes in drinking water on the productive performance (live weight, body weight gain, feed consumption, feed conversion and water consumption) and to determine the economic impact of using electrolytes. The chicks were randomly distr...
