this purpose. Some completehutch designs provide for anenclosed wooden rear compartmentfor w<strong>in</strong>ter protection,although this compartmentshould be blocked <strong>of</strong>fdur<strong>in</strong>g summer monthsbecause the rabbits will getoverheated if they hide or nest<strong>in</strong> it. In unusually cold periods,hutches or cages can bewrapped with <strong>in</strong>expensivepolyethylene sheets or oldblankets if necessary.Heat StressManagementIn periods <strong>of</strong> extreme heat,proper management techniquescan be followed toma<strong>in</strong>ta<strong>in</strong> normal fertility levels<strong>in</strong> commercial breed<strong>in</strong>gstock. The buck is more pronethan the doe to experience<strong>in</strong>fertility <strong>in</strong> the summer.Buck fertility may decl<strong>in</strong>ewhen temperatures are above85 o F for several consecutivedays, which actually representsseveral months out <strong>of</strong>the year <strong>in</strong> <strong>Texas</strong>. Youngbucks (6 to 9 months old)have higher fertility and sexdrive than older bucks andcan be mated to does dur<strong>in</strong>gthe summer season to achievereproductive success.To further cope with heatstress conditions, one strategyis to ensure that the <strong>in</strong>sidetemperature where the rabbitsare housed is at least 10degrees cooler than the outsidetemperature.Thermometers can beplaced both <strong>in</strong>side and outside<strong>of</strong> the shed (or other build<strong>in</strong>g)as a check. A well-ventilatedshed or even shade trees willhelp meet this objective.Dur<strong>in</strong>g the heat <strong>of</strong> the day,you can place spr<strong>in</strong>kler hoseson the ro<strong>of</strong> <strong>of</strong> the shed orhutches and turn them on andwet the grounds around thehutches with a garden hose topromote evaporative cool<strong>in</strong>g.Water directly reduces thesurround<strong>in</strong>g temperature, and,when water comes <strong>in</strong> contactwith prevail<strong>in</strong>g breezes, thiscools the stock. If necessary,you can also freeze plastic s<strong>of</strong>tdr<strong>in</strong>k bottles filled with wateror water-soaked burlap sacksor towels and place them <strong>in</strong>the cages. You can even putice <strong>in</strong> the cages on especiallyhot, humid days when there isno breeze. In particularlyadverse situations, large fansor commercial fog mist systemsmay be justified. Becareful to avoid gett<strong>in</strong>g theanimals wet.Proper tim<strong>in</strong>g and consistency<strong>in</strong> implement<strong>in</strong>g theseheat stress management <strong>in</strong>terventionsis vital to the comfort,productivity, and evensurvival <strong>of</strong> the stock.Basic Hous<strong>in</strong>g andEquipmentIf you do not already have ashed, there is little economicjustification for the expense <strong>of</strong>build<strong>in</strong>g a new shed just forrais<strong>in</strong>g rabbits. A wiser <strong>in</strong>vestmentwould be to construct acomplete rabbit hutch (Figure1). You should locate thehutch <strong>in</strong> a safe area (for example,under shade trees or <strong>in</strong> afenced lot), so that the rabbitswill be protected from the naturalelements, <strong>in</strong>clud<strong>in</strong>gpredators. Wire cages aredesigned for hang<strong>in</strong>g <strong>in</strong>sidesheds or other build<strong>in</strong>gs.Cages are usually about 30<strong>in</strong>ches wide, 30 <strong>in</strong>ches long,and 18 <strong>in</strong>ches high for doeproduction or fryer growthpurposes. For grow<strong>in</strong>g fryers,one cage for every 2 does isrecommended. Ideally, fryerscan be grown <strong>in</strong> used cages to<strong>of</strong>fset costs. Bucks may beaccommodated <strong>in</strong> cages withdimensions <strong>of</strong> 30 x 24 x 18 or24 x 24 x 18 <strong>in</strong>ches, depend<strong>in</strong>gon the size or breed <strong>of</strong> rabbit.Commercially availablefeeder and automatic water<strong>in</strong>gequipment can be used <strong>in</strong> thebackyard rabbit operation(Figure 2). Water bottles orcrocks are also popular. Nestboxes are discussed <strong>in</strong> theReproduction section. For<strong>in</strong>formation on cages, feeders,waterers, and other equipmentspecifically designed forrabbits, you can request a freecatalogue from the BassEquipment Company (P.O.Box 352, Monett, Missouri,65708 or 1-800-798-0150).Breeds andSelectionBreed<strong>in</strong>g StockThe American <strong>Rabbit</strong>Breeders Association recognizesmore than fifty breeds <strong>of</strong>rabbit. However, most <strong>of</strong> thesebreeds are bred and raisedstrictly for fancy or showexhibition. In general, a fancybred doe is unsuitable foryear-round meat production.In other words, fancy rabbitsare selectively bred for theshow table rather than for themeat table. Examples <strong>of</strong> showtable traits <strong>in</strong>clude body,head, and fur type and coatand toenail color.Similarly, rabbits from petstores and flea markets arenot a good source <strong>of</strong> breed<strong>in</strong>gstock. This is because suchrabbits have an unknownbackground or are not from4
