RECOMMENDATIONS<br />

Based on (Ullrey et al 1997)<br />

• All collections MUST undertake regular analysis of hays for dry matter,<br />

crude protein, acid detergent fibre, neutral detergent fibre, lignin,<br />

calcium, and phosphorus in a laboratory with demonstrated expertise.<br />

• Elephant diets should be based on a grass hay of known composition.<br />

• Using published recommendations, any supplemental sources of<br />

energy, protein, minerals, vitamins or fatty acids required should be<br />

calculated and extra feeds added to the diet accordingly.<br />

• Consideration should be given to the regular measurement of<br />

circulating α-tocopherol levels to ensure that elephants are obtaining<br />

adequate dietary vitamin E.<br />

• <strong>Elephants</strong> should have daily outdoor exercise to ensure adequate<br />

synthesis of vitamin D3, which is essential for promoting the absorption<br />

and utilization of calcium and phosphorus.<br />

• Water and grass hay with an ADF of >30% should be provided ad<br />

libitum.<br />

• All dietary changes should be made gradually (over 1-2 weeks) to avoid<br />

digestive upsets.<br />

• <strong>Elephants</strong> should be regularly weighed (or measured) and the diets<br />

altered accordingly to avoid weight loss or obesity.<br />

• No changes to the diet should be made without consultation with the<br />

nutritionist and veterinarian.<br />

3.4.3 Hand Rearing<br />

Information on hand rearing has been extracted from a report by Colleen<br />

Kinzley and Karen Emanuelson of Oakland <strong>Zoo</strong>, which was compiled from<br />

the Elephant Hand Raising Notebook (Kinzley 1997). Milk samples have been<br />

analysed (Mainka et al 1994) and data on composition suggests that diluted<br />

whole cow’s milk (1:1) with supplemental vitamin C fed at intervals of 2 to 3<br />

hours, totalling 4-5 litres per day (Dierenfeld 1994). At the end of the first<br />

month undiluted milk with added saturated fat should be used. Bovine<br />

bottles and nipples are suitable. Grober Company located in Cambridge,<br />

Ontario produces the most commonly used elephant milk replacer in North<br />

America and full instructions are provided with this. Colostrum replacers<br />

have also been given in the first week. It is also recommended that a plan to<br />

reintroduce the calf to the dam should be drawn up. There are instances of<br />

successful reintroduction after a period of up to 10 days. In some cases the<br />

dam can be milked, enabling the calf to receive some colostrum and milk.<br />

Ideally elephant milk replacer should be used (Reitkerk et al 1993).<br />

To summarise it is recommended that for handrearing Grober’s milk<br />

replacement is used. Two versions of Elephant Gro are available, one<br />

formulated for African and one for Asian <strong>Elephants</strong> (www.grober.com).<br />

Colostrum should be given, ideally that milked from the dam. If this is not<br />

possible artificial or cow colostrums can be used or elephant plasma<br />
