We discussed seminal plasma and how it affects sperm, and the role extender plays in a situation like shipping semen.  Based off that discussion, answer each of the following questions with just one of the two words in quotes.   1. Is seminal plasma considered “good” or “bad” for sperm if they are in contact for extended periods of time?  2. Although it must be vacated from the uterus, is seminal plasma considered “beneficial” or “detrimental” to the mare’s uterus following breeding?  3. With frozen semen, seminal plasma is almost entirely removed from the ejaculate prior to freezing.  Frozen semen straws therefore contain very concentrated quantities of sperm in a fluid medium mostly consisting of extender.  So knowing that, and based on your answers above, if a mare was prone to retaining fluid following breeding, would frozen semen be a “good” or “bad” choice for her as a breeding method? 

The feto-placental unit is very important to establishing and maintaining the equine pregnancy. 1) Describe what is meant by the term “feto-placental unit.” (1 pt) 2) How does it affect the profile of both the mare’s A) estrogens and B) progestins seen during the fetal period? (4 pts)

Besides and AV, list three other larger pieces of equipment (not a horse!) that you would want to buy if you were starting up a breeding program and needed to collect semen from stallions in order to AI your mares: 

Besides general physical condition, list 2 major areas (= not parts of one category) that could be evaluated for a stallion on his BSE, and briefly describe 2 reasons why an owner would want a BSE done. Areas evaluated: 1. 2. Reasons to do a BSE: 1. 2.

The following semen evaluation number for Total Concentration was attained for a 10 yr old, healthy stallion in the middle of May – mark if the estimated number for his ejaculate would be considered Low, Average, or High:  220 million / mL 

The earliest you can ultrasound a mare to detect a pregnancy is day 16 post-ovulation.

A stallion owner is trying to decide between the different breeding methods available to him.  His stallion is 4 years old and has never been bred before. The owner has about 6 or 7 mares of his own he would like to breed to his stallion, but the stallion has also generated interest from mare owners in other states. 1) Give this owner your recommendation for which method to use (choose only one). 2) Provide the reasoning behind your suggestion, include two potential advantages and two disadvantages for this option.

All instruments playing the same melody is a type of Polyphonic texture.

When determining if a mare is ready to be bred, we often will evaluate signs of estrus by scoring her behavior.  Match the score with the behavior:
