Abstract
This study was carried out at the Animal Farm of the Department of Animal Production, Faculty of Agriculture, Minia University during the period from January, 2001 till February, 2002. This study included two experimental periods, the growth period (from January till August 2001), and the reproductive period (from September 2001 till February 2002).
The main objective of this study was to evaluate the effects of dietary Al supplementation at 1000, 2000 and 3000 ppm on some productive, reproductive and physiological traits in rabbits.
Ninety six (48 males and 48 females) of weanling New Zealand White rabbits (5 weeks old) were used at the beginning of the experiment and were divided into 4 groups (12 males and 12 females in each). The averages of body weight were ranged from 478 to 498 gm for young males and from 464 to 489 gm for young females rabbits. The rabbits were fed ad libitum on pelleted commercial diet containing alfalfa hay 37.5 %, barley cereals 16%, yellow corn 20 %, wheat bran 15 %, soybean meal 10 %, sugar beet molasses 1%, calcium carbonate 0.15 %, sodium chloride 0.1%, as well as minerals and vitamins mixture 0.25 % .
The experimental diet contents were mixed with Al sulphate compound to supply the following treatments : -
1- Control diet : pelleted commercial diet (free from Al).
2- Diet of first treatment (T1): pelleted commercial diet containing Al at 1000 ppm .
3- Diet of second treatment (T2): pelleted commercial diet containing Al at 2000 ppm .
4- Diet of third treatment (T3): pelleted commercial diet containing Al at 3000 ppm .
