The key driver of profitability is the
number of kittens weaned per doe per year. A determinant of this is
the number of litters per year for each doe. As commercial rabbit
farmers it is imperative to learn how
to accurately diagnose pregnancy at 10 to 14 days of gestation.
Possible
Benefits
Accurately determining provides the rabbitry manager with some very
valuable information. This procedure saves waiting the additional 17
days to see if the doe is pregnant. There are many advantages for
pregnancy detection. These are as follows:
1. Allows
the rebreeding of the non-pregnant does immediately. This increases
the efficiency and the usefulness of the doe. This allows the
non-pregnant doe that is rebred, the opportunity to be more than
half way into another pregnancy. This is beneficial as it allows the
most possible number of kits from that individual doe per year.
2. Allows
the manager to maintain the doe in proper and appropriate body
condition. Pregnant does have increased nutritional requirements
during the last one-third of gestation period and require increased
feed intake to insure the healthiest offspring possible. Does that
have the feed intake increased and are not pregnant have a tendency
to get fat and will have excessive fat around the reproductive
organs. Does that are too fat tend to have reproductive problems and
many become difficult to join. Often these does have to be culled
from the herd for lack of productivity. This is a dramatic financial
loss when breeding stock is lost from the herd.
3. Saves
time, money and labour. Preparing, inserting and maintaining a nest
box for the doe requires sanitation, filling the box with nesting
materials, time and effort in placing the box in the doe's cage and
supervision. In addition to the increased amount of feed required
when the doe is not pregnant. These are all wasted expenses and
effort.
4. Saves
and prevents disappointment. Everyone anticipates the arrival of a
new litter of rabbits.
