Ruminant Nutrition

Nutritional Evaluation of Feedstuffs

  • Application new techniques for the determination of chemical composition of forage and concentrate.
  • Application of in vivo, in situ and in vitro methods for ruminal and post-ruminal digestibility of common and new feedstuff.
  • Ruminal degradability of forage and concentrate.
  • Effects of TMR rations and different ratios of forage to concentrate on rumination, chewing activity and ruminal parameters of dairy cattle.
  • Determination of  the passage rate and digestion kinetics of feeds in ruminants.

 

Feed Processing

  • Applying different methods along with additives for forage silages.
  • Grinding, eradiation, heating, steam rolling, and flaking of cereal and oil seeds.

 

Dairy Cattle Metabolism and Milk Production

  • Application of feed additives for improving ruminal fermentation rate and increasing the quality and quantity of milk production.
  • Feed processing to change the ruminal parameters, hepatic metabolism, and save energy.
  • The relationship between ruminal parameters, blood metabolites, milk production and milk quality.
  • Alterations of ruminal bacterial, protozoa and fungi populations in response to different rations.
  • Application of the protected amino acids and trace minerals for improving milk production and the immune system.

 

Sheep Metabolism

  • The effect of different forages and concentrates on ruminal parameters, blood metabolites, growth rate, and meat quality.
  • Compensatory growth rate of lambs.
  • Hormonal evaluation in response to nutrition.

 

Weaning Age of Calves

  • Feed additives and essential oils for reducing the weaning age.
  • The use of management methods to enhance growth, health, ruminal microbial flora and fermentation.
