Theses and Dissertations--Animal and Food Sciences
Eight steers were used in a replicated 4 x 4 Latin square design experiment to study the rumen metabolism of polyunsaturated fatty acids. The animals were fed a concentrate diet based on cracked corn grain, corn silage and hay fescue (K31). The dietary fat treatments were a negative control, tallow added at 60g/day, fish oil at 60g/day and heterotrophically grown microalgae high in DHA at 100g/day. Treatments were incorporated immediately prior to feeding each day and dosed through a ruminal fistula mixed with 0.45kg of the diet. Animals were fed at 1.75 x NEm once daily during adaptation then switched …
Effects Of Feeding A Yeast-Based Supplement Containing Docosahexaenoic Acid (Dha) From A Heterotrophically Grown Microalgae, Vitamin E, And Selenium On Stallion Sperm Motion Characteristics, Lauren D. Goedde
Theses and Dissertations--Veterinary Science
The use of cooled and frozen stallion semen has become quite popular. However, there are some stallions that have sperm that are quite susceptible to cold shock. Thus, there is a need for techniques that will alter sperm so that they can withstand the stresses of cooling and freezing and thus improve pregnancy rates achieved with cooled or frozen spermatozoa. Studies have shown that a diet high in omega-3 (n-3) fatty acids can improve the motility of cooled and frozen/thawed sperm. Many of the omega-3 fatty acid products for stallions have low levels of docosahexaenoic acid (DHA) and are based …
