The Rabbit
Research Program at TAMUKThe Rabbit
Research Program at TAMUK
A rabbit research program was established in 1994 at Texas A&M University-Kingsville.
The facility is 80 feet long and 17 feet wide. The building is narrow to help
improve air flow to keep
the rabbits cool. The barn faces a southeast direction
to maximize the prevailing wind air flow for better circulation. Engineers have
designed the barn to be 10° F cooler inside than the outside temperature.
This facility has a metal roof with insulation underneath to help keep inside
temperature cooler. These interventions are especially important with the extreme
high temperature that do occur quite often in south Texas. During the cooler
months there are adjustable plywood panels on both the southeast and northwest
sides of the barn that can be lowered to protect the rabbits against drafts
or storms.
fryers
per year. For example, a doe will be bred and 14 days later she will be palpated
for pregnancy. If the doe is pregnant, 14 days later a nest box will be placed
in her cage. The same doe would be serviced again 14 days postpartum. If the doe
is not pregnant, she will be bred back immediately and palpated again 14 days
later. The replacement does and bucks are first mated at 5 or 6 months of age.
All rabbits are housed in commercial wire cages that are equipped with an
automatic watering system. A part-time student manager maintains the research
facility and keeps the operation going smoothly. Graduate students conduct
research experiments as part of their specialization training.
the commercial
meat rabbit industry, was obtained in the mid-1980's from Pel-Freez. In recent
years, this line has been crossed with commercial lines from Florida and
Louisiana. This composite maternal line is well adapted under hot and humid
conditions. There is little to no fancy or show breeding in this line. Does exemplify
desirable maternal characteristics, such as large litters, well developed nests,
good milking ability, and strong maternal instincts. The breeding management regime
involves a 14-day breedback system.
Altex - This is a commercial sire breed of rabbit that was developed in Alabama
and Texas. Foundation
breeds were Flemish Giant, Champagne d' Argent, and Californian.
The Altex was genetically selected for heavy 70 day market weights for over
15 generations. Color markings are that of a Californian (CAL), but weights are heavier
ranging from 10 to 20 pounds. Altex x New Zealand White crossbred fryers
typically reach market weight a week earlier than NZW purebred fryers. Another
recommended cross is the mating from an Altex buck to a CAL X NZW crossbred doe.
Breeding stock
($20.00) can be purchased. We sell at the door. It is emphasized that these
are commercial-bred rabbits. They were not developed to do well at rabbit
shows. We want our rabbits to be long-bodied with large ears, non-dense fur,
etc., so as to be more heat tolerant and better litter producers. For more information about the Altex breed, the following paper can be read
which was published in Domestic Rabbits Magazine (Sep.-Oct. 1996,
24(5):20-21).

A Heifer International Publication. This book was written as a series of lesson plans for professionals (e.g., extension workers, missionairies, Peace Corps volunteers, and social workers) who train poor people, especially in the lesser developed countries, how to start small-scale, backyard rabbit operations that are supported by on-farm resources to produce inexpensive meat, to improve small farms, and to increase family income. A section of the book covers the steps in designing and implementing sustainable, grassroots level rabbit projects. Copies are available by directly contacting Heifer (http://www.heifer.org)
The Rabbit - Husbandry, Health and Production by the eminent French rabbit research team: Drs. F. Lebas, P. Coudert, H. deRochambeau and R.G. Thebault (1997, 2nd Edition). This is an outstanding text that covers technical aspects of rabbit production (published by the FAO).
