Research Abstract
ANS3043
Growth & Development of Domestic Animals
Objective:
The objective of this
assignment is to provide an opportunity for the student to explore in-depth, an
area of interest in the field of physiology of reproduction. This research
abstract is also intended to introduce the student to objective, critical
evaluation, and abstraction of scientific reports and reviews, and scholarly
scientific writing. A research abstract will introduce the student to one of our
most valuable resources, the library, accessible through the web.
Topic:
The subject of the research
abstract may be any topic of interest to the student in the following areas:
Abstract A - Endocrinology
Abstract B - Placental and Fetal Development
Abstract C - Muscle, Bone and Fat Development
Abstract D - Hormonal Regulation of Growth
Guideline:
1] The abstract will be a
maximum of one page (double spaced, Times Roman font-size 12, 1 inch margins)
that contains no typographical or spelling errors.
2] Scholarly English is required. A
single article from a scientific journal, at least 5 pages in length, and
published 2006 or 2008 is to be reviewed and abstracted in a style similar to the
attached example.
3] Each abstract from a
different journal introduces the student to four different journals. Journals
that are recommended but not limiting are Journal of Animal Science, Journal of
Dairy Science, Journal of Poultry Science, Endocrinology, Meats Science, and
Journal of Food Science. Articles published in refereed journals are reviewed
critically by independent scientists and only those that meet the standards for
a particular journal are published.
4] Scientific Journals at the Medical School and Marston Library are accessible via the web under Links..Libraries. You must logon with your Gator link account in order to access these journals.
Instructions for locating Journal articles for abstracts:
1. Go to ufl.edu, under Academics (left side), hit the "libraries link".
2. Go to GeoIrge A. Smathers libraries.
3. Under the heading research gateway, go to "off campus access".
4. Log in on the left side using your gatorlink username and password. Note: (If it does not work, check in with a librarian to put you in the library system.)
5. Go to the "UF Smathers Library" link.
6. Under the heading "find" use the "Databases" link.
7. It will say "By title", type in the database you wish to use.
(I use the database Pubmed, it has worked well in the past).
8. Click on "pubmed". (or other database link).
9. Now search for the topic. (You can also search by topic and date, which will put the newest articles first). (i.e. 2006-2008)
10. Now comes the tricky part, if the article is available in full text, there will be a link when you open the abstract in the top right hand corner of the article page. Usually saying "FULL TEXT" and "FREE". Some are not available in full text, due to UF not subscribing to that particular journal. It might take a few trys, but this should work. Print in PDF format to save ink and for an easy read..
5] Staple a copy of the complete article
reviewed to your abstract.
Grading: This assignment and
unannounced quizzes represent 15% of the final grade. Reports not meeting
deadline dates will be penalized a letter grade. Grading will be based on the
above instructions including content, organization, clarity of presentation, and
scholarly English.
Activities
Honors Section: Students participating in the Honors Section have the additional responsibility of attending a one hour session offered by Dr. Sally Johnson. This section will offer students an opportunity to explore additional material particularly in the molecular realm of growth and development of the embryo to the mature animal. Students will be afforded an opportunity to shadow scientist conducting research in this area of biology. Information on the Honors Section can be found under
Teaching at website www.animal.ufl.edu/fields
Seminars:
A
second honors section will be opened to give students an opportunity to attend seminars on some aspect of Developmental Biology that occur
across campus throughout the semester. These seminars offer undergraduate
students an opportunity for exposure to the latest
research presented by leading scientist in their area of expertise, meet the
faculty, and graduate students and in general observe the scientific enterprise

Effects of Twinning on Gestation Length, Retained
Placenta, and Dystocia.
S.E Echternkamp, and K. E. Gregory, USDA, ARS, Roman L.
Hruska, Objectives: The purpose of this study was to evaluate the effect of twinning on gestation length and the incidence of retained placenta and dystocia. Study Design: Incidence and causes of shorter gestation length and increased retained placenta and dystocia associated with twinning were evaluated for 3,370 single and 1,014 twin births in a population of cattle selected for natural twin births. An increase in twinning rate for cattle can be achieved through genetic selection for replacement heifers and sires. Twinning in cattle is reported to increase the incidence of dystocia and/or retained placenta, lower calf survival, lengthens the postpartum interval, and decrease conception. Obstetrical assistance was provided for cows gestating twins. Dystocia was evaluated subjectively using descriptive scores. For twins, each calf was assigned a dystocia score. Results: The incidence of retained placenta was significantly higher in females delivering twin calves. Premature induction of parturition with glucocorticoids and/or prostaglandins increases the incidence of retained placenta. Incidences of dystocia were approximately twofold greater and differed in physical nature for twin births which resulted primarily from abnormal presentation of head and/or legs for one or both twin fetuses. Conclusions: The increased incidence of fetal malpresentation with twins may result from the higher circulating concentrations of progesterone and estradiol found in cows gestating multiple fetuses, the shorter gestation length and increased incidence of dystocia and/or retained placenta and the associated effects on calf survival with twin births impose constraints to maximizing economic returns from twinning in beef cattle. A high level of management is required for twin-producing dams and their calves during the calving season to achieve the increased productivity possible with twinning technology in cattle.
