WildLife Group of the SAVA Dehorning of a rhinoceros – J.G. du Toit Reasons for dehorning a rhinoceros is that a thick layer of horn is wasted with the cutting procedure. 1. The hand saw cuts slower but less waste of horn occur during the cutting procedure. A hand saw can be used as a standby tool for the chain saw when mechanical problems occur. 2. Protect the eyes (heat and fumes) and ears (noise) of a rhinoceros when a chain saw is used. 3. The down time of a dehorning procedure must be less than 10 minutes. 4. Cut horn horizontally just above the hairline. Care must be taken with young animals where the sinus is still well developed in the base of the horn. Do not round the edges of the horn because the horn will crack in the middle of the base and reduce growth and horn production. 5. Cut the front horn first and then the back horn. 6. The horn must be cut above the hairline. 7. The horns of young animals must not be cut to low to prevent cutting in the sinuses Planning a dehorning operation Factors to consider when dehorning rhinoceroses Poaching was always 0.1% of the white rhinoceros population of South Africa. The rhinoceros horn is part of the same shopping trolley of the international smuggling syndicates that is filled with drugs, abalone, cigarettes, weapons and human trafficking. The rhinoceros must be dehorned for commercial reasons and to create a legal market for the product. Ranching for horn is at least ten times more profitable than cattle ranching on the same area of land. The sale of rhinoceros horn will earn foreign currency for the country. The dehorning of rhinoceros will give the live animal a value as explained in Chapters 9 & 14. The philosophy is if you stop a free market you create a black market – this will be the end of the free living rhinoceros. However in certain cases the owners cannot dehorn their animals for reasons such as tourism or predation. This should not prevent ranchers who prefer so sell the horn of their animals instead of hunting them. According to the Norms and Standards described in Chapter 2 the following is applicable. When live rhinoceros are darted for translocation, treatment or any other management purpose, samples of the horns and blood must be collected by using the DNA kits as provided by the Veterinary Genetics Laboratory at Onderstepoort. The dehorning must be done while the rhinoceros is immob [^Y[]\HۙB[\H\\\[ۈوH]\[\X[\YܙBH\Z]\\HH[\ZܛB[[X[ [ܝ[\Hܛ]\B؝Z[YHHݚ[X[]]ܚ]H ۝X]Z[š[\\ KZܛ[X\]YBHZ[]]܈Y[][H\Y BY[YHوHZ[]\]Zܛ[[BۙH]ZXK\YX[Hۋ][YH[\ق[[[ؚ[^][ۈH[\ˈH\Y[YBMXۛZX‘Zܛ[\HH^\\HYHHYܝق[[H[[X[[H\X]Y]H[[[ؚ[^][ۈ\ˈHوHZܛ[›\][ۈ[\[ۈH[\[][ۂ[]KH^HوH\XKHY]][ۈ\Kܘ\HوH\Z[HYܙYHوX]X][ۂوH[\\\[]ܛHX\B[X\܈ZXH[^\Y[HوH\\BX[KX\Y\[X]\وH\[قZܛ[\HNH  T \[\Š\[X]Y܈ܝY\][ۘ[\H[ T H H\[\܈]]H[ [^B^[܋ LJKH[HYXY\BܙY[[\HZܛH[[X[ Y\\[^ JK(HH[X\\X\\HZܛ[[X[™YX][B
