3. Zeolite Microporous, aluminosilicate minerals
Found mainly in volcanic Rock
245 unique frameworks
Clinoptilolite
Natural occurring zeolite
(Na2,K2,Ca)3Al6Si30O72·24H2O
Zeolite A
Synthetic for of zeolite

4. Clinoptilolite Studies have shown to lower occurrences of Milk Fever
Increase DM digestibility and increase digestibility of individual nutrients
Has also shown to increase ADG and feed efficiency in Feedlot Cattle
Shown to lower BUN in Dairy cattle supplemented with zeolite
Has shown to have a high affinity to bind to ammonia

5. Objective of Study
objective of this study is to determine if supplementation of Clinoptilolite to Dairy Cattle will Lower BUN, MUN, and Increase Nitrogen utilization

6. Experiment Materials Lactating Dairy Cattle 15 – Control
15 – Zeolite Treatment (High Inclusion Rate)
15 – Zeolite Treatment (Low Inclusion Rate_
TMR
Control
Inclusion Rate of 2.5% (low) and 5% (high) of DM diet
Clinoptilolite – 85% purity
Equipment needed to take blood and milk samples from cattle

7. Experiment Methods 3 Treatment Groups
Animals will be fed diet for 45 days
Blood and Milk samples will be taken daily
Samples taken when BUN and MUN at highest concentrations
Get urine sample
Measure BUN and MUN
Measure ammonia concentration
Ammonia quantified by titration
Fat must be removed before measuring ammonia
SAS will be used for statistical analysis of results

8. Expected Results
See a lower BUN and MUN in animals that are supplemented with zeolite
See a lower concentration of ammonia in the urine of the supplemented animals
See a difference in the two different inclusion rates
See a difference in the nitrogen utilization between all three treatment groups

9. Conclusion
Increase nitrogen utilization and decrease nitrogen loss decreasing environmental effects
Increase in nitrogen utilization → better use of protein fed to animal
Supplementation to animals that receive high amounts of nitrates could help with protein metabolism and glucose utilization
