Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

992
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Area of Science:

  • Animal Science
  • Ruminant Nutrition
  • Animal Behavior

Background:

  • Dairy cattle exhibit feed sorting behavior, selectively consuming portions of their total mixed rations (TMR).
  • This sorting impacts individual nutrient intake, reduces the nutritional value of uneaten feed, and is linked to negative health and production outcomes like reduced rumen pH and altered milk composition.
  • Factors influencing feed sorting include ration characteristics, feeding strategies, and herd-level management, with individual variability suggesting additional influencing factors.

Purpose of the Study:

  • To explore the influences of ration characteristics, feeding strategies, and management factors on feed sorting behavior in dairy cattle.
  • To understand the underlying reasons for feed sorting and identify methods to reduce it on farms.
  • To investigate the development and persistence of feed sorting behavior in young calves and its potential feedback mechanisms.

Main Methods:

  • Review of numerous studies examining feed sorting in mature cows and young calves.
  • Analysis of how forage inclusion rate, particle size, dry matter content, and feeding strategies affect sorting behavior.
  • Exploration of herd-level factors, individual variability, early life exposure, and postingestive feedback mechanisms.

Main Results:

  • Feed sorting is influenced by forage characteristics and feeding strategies, with increased feeding time potentially exacerbating the behavior.
  • Young calves exposed to mixed diets early may develop persistent sorting habits.
  • Cattle demonstrate a capacity to adjust sorting behavior, favoring physically effective fiber to mitigate low rumen pH, indicating a role for postingestive feedback.

Conclusions:

  • Feed sorting in dairy cattle generally needs to be reduced through management or by discouraging early development of the behavior to ensure optimal nutrition.
  • While often detrimental, feed sorting may serve functional roles in specific scenarios.
  • Further research is essential to fully elucidate the feedback mechanisms governing feed selection and sorting across different cattle life stages.
