Concentrate Levels And Saccharomyces Cerevisiae Affect Rumen Fluid-Associated Bacteria Numbers In Dairy Heifers, G. J. Lascano, G. I. Zanton, A. J. Heinrichs
Concentrate Levels And Saccharomyces Cerevisiae Affect Rumen Fluid-Associated Bacteria Numbers In Dairy Heifers, G. J. Lascano, G. I. Zanton, A. J. Heinrichs
Dairy Science
Total viable rumenbacteria counts through the use of colony-unit forming assays lack accuracy because they only include culturable bacteria capable of initiating cell division. Thus, bacterial counts can be underestimated. The use of fluorescent characteristics of cell membranes allows flow cytometry to enumerate and distinguish dead from live bacteria cells. The objective of this experiment was to investigate the viable and total ruminal bacteria counts when 3 levels of forage:concentrate in diets were fed at restricted levels with the addition of Saccharomycescerevisiae (YC). Three cannulated post-pubertal Holstein heifers (age 18 ± 1.0 months) were fed corn silage (CS)-based diets in …

Algae As An Economical Protein Source For Dairy Cattle Nutrition, Brian Azevedo
Algae As An Economical Protein Source For Dairy Cattle Nutrition, Brian Azevedo
Dairy Science
Dairying continues to change with economic and environmental demands of today’s fast moving society. Feed costs continue to rise and now account for a large majority of expenses on dairies; especially protein, which has become expensive to purchase. I believe that Algae can serve as a possible solution to aid in alleviating this problem. Algae grow rapidly and consume undesirable carbon dioxide to release oxygen to the environment, making it an environmentally friendly source of feed. There are particular strands of algae that are high in protein. During the course of this project, I intend to discover how effective protein …

Usage Of The Penn State Forage Separator For Evaluating Particle Size Of Tmrs, Ashley Rene Garcia
Dairy Science
Particle size has many effects on the cow. Adequate forage particle length is necessary for proper rumen function. Dairymen are also having a hard time measuring particle size. Proper particle size distribution of feeds is an important part of ration formulation. Management of forage particle size starts with harvesting forages at the proper stage of maturity. Chopping the crop at the right length helps to achieve the desired particle length in a TMR. Measuring particle length of the forages is only a portion of the solution. Analyzing the TMR particle size is the main goal in measuring the distribution of …

Cal Poly’s “Learn by Doing” philosophy is one of the great traits that the University holds. However it is this philosophy that is also one of the most expensive and hardest to maintain. “Production agriculture majors use more dollars per unit than any other major in the entire college,” as Dr. Golden stated during his talks about herd cut backs. Never the less the College of Agriculture prides itself on supplying knowledgeable and experienced students to the industry that supports it so much. One of the amazing classes that are offered at the university is the Dairy Science Artificial Insemination …
Rumen Fermentation Pattern Of Dairy Heifers Fed Restricted Amounts Of Low, Medium, And High Concentrate Diets Without And With Yeast Culture, G. J. Lascano, A. J. Heinrichs
Rumen Fermentation Pattern Of Dairy Heifers Fed Restricted Amounts Of Low, Medium, And High Concentrate Diets Without And With Yeast Culture, G. J. Lascano, A. J. Heinrichs
Dairy Science
Restricted feeding and highconcentratediets are potential strategies for growing dairyheifers. Ruminal manipulation with additives such as Saccharomyces cerevisiaeyeastculture (YC) has been shown to alter digestibility when added to this type of diet. An experiment was conducted to investigate the ruminal fermentation and in situ digestibility of diets with 3 different levels of forage to concentrate (F:C) fed at restricted intake without and with YC addition. Three cannulated post-pubertal Holstein heifers (age 18.0 ± 1.2 months; body weight 449.6 ± 19.7 kg) were feddiets consisting of corn silage as the sole forage source in a 3 period (35-day) Latin square …
