In the past it has often been difficult to hand- rear certain species of antelope, but recently the Lincoln Park Zoo, Chicago, has had the oppor- tunity of hand-rearing Grant’s gazelles G a d l a granti with good results.

When young antelopes are rejected or have difficulty in suckling they are placed in our chil- dren’s zoo. One such animal, a female, was born OR 28 May 1968, and it was immediately seen that she was having difficulty in suckling. The subsequent formulae were as follows:

Day I : Colostrum from a domestic cow was given to the infant.

Day 2 : 50% colostrum, 25”/0 tap water and 2jo/o

evaporated milk, by volume. Day 3: Feeds consisting of 66”; tap water, 3496

evaporated milk and six drops of a multi- vitamin preparation.

Day 4 onward to the end of bottle-feeding: 34y0 evaporated milk, 66% tap water, 18 drops of multi-vitamin preparation. T o 225 ml(8 oz) of this formula were added three teaspoons of pablum.

From the end of the first week 0.6 ml cod-liver

Feeding was by means of a standard 8 oz plastic oil was also added per 225 ml(8 oz) of formula.

feeding bottle fitted with a large holed nipple. Force-feeding was necessary for the first 24 hours, but subsequently the baby drank eagerly. We have found that the addition of a teaspoonful of Karo syrup makes the formula more palatable.

Feeds were given six times during each 24 hours, five feeds during the day and one at night. At each the young animal was given as much as it wanted; the most being taken at one time amounting to 510 ml (18 oz). After day 18 the night feed was discontinued, and each feed con- sisted of 340 to 400 ml (12-14 oz) of formula.

At the age of four weeks the gazelle was offered alfalfa and D & F Chow. When it was accepting these foods readily, it was moved to our hoofed stock area and given cow’s milk from a pan once daily in addition to the alfalfa and D & F Chow.

We have also found that this formula and feed- ing schedule is very successful for Ihand-rearing Thornson’s gazelle Gazella thomsonii.

The successful breeding of pelicans is still a rare event in zoos generally, but since 1957 pelicans have laid eggs every year at East Berlin Zoo. At first, it was only the Crested pelican Pelecanus crispus and the White pelican P. onocrotalus, but

in later years eggs were also laid by the Pink- backed pelican P. rufiscens, the Rough-billed pelican P. erythrorhynchos and the Brown pelican P. occidentalis. It was not until 1961 that a young White pelican was hatched. This was the first
