Joe's Rules
In Joe's Rules, what is the first priority of the cow?
I will live.
What is the difference between vitreous and flowery corn?
Vitreous- yellow glassy starch
Floury- white/powdery (softer)
List 5 factors that can affect DMI.
-Body Size, Production, Water Availability, Ration, Feeding Frequency, Ration Changes, Ration Moisture Content, Social Interactions, Forage Quality, Feed Access, Feed Management, Feeding Sequence, Bunk Managment, Environment, Health
What are the absorptive structures in the rumen?
Papillae
Metabolizable Energy =
DE- urinary+ gaseous loss
In Joe's rules, what is the second priority for the cow?
I will feed my calf.
In what way could there end up being 3 rations on a dairy, and what should the goal be?
-Formulated by the nutritionist
-Mixed by the feeder
-consumed by the cows
-goal is to have the same ration for all 3 or as close as possible
What are the three main factors to consider when looking at what affects DMI?
The animal, the feed, and the human
What shape is the absorptive surface in the reticulum?
Honeycomb
Gross Energy
DE+ Fecal Loss
In Joe's Rules, what is the third priority of the cow?
I will reproduce.
What do animals do?
Maintanence
Growth
Production
Movement
List two ways we can maximize DMI.
-always have fresh feed accessible to cows, high quality and quantity of water, ( balance, mix, and deliver rations properly), high-quality ration, consistency and gradual changes, healthy cows in a good environment, keep cows chewing and ruminating
What is the absorptive surface in the omasum?
Digestible Energy =
NE+heat+urinary+gaseous lsses
Based on the rations you have balanced,what is a way the concept of joes rules, and ration balancing can be connected?
Considering the differences for animals at maintanence/growth/weight
What are some things we can do to monitor DMI?
- use scales, know the amounts of feed fed and refused, use moisture tests, Know the number of cows in the group, Calculate and Graph DMI
