Abstract

      This research was conducted to study the effect of using the product (ALiplus) on the components of the diet on growth and some characteristics of calves carcasses. Thirty local calves, close in age, with an average live weight (206.51) kg, were randomly divided into two nutritional groups, close in ratio of crude protein and metabolic energy. The first treatment included feeding the calves on a standard diet consisting of (soybean meal, yellow corn, wheat bran, wheat flour, barley, molasses of cane, limestone, and salt), while the second treatment included feeding the calves on a ration treated with (ALiplus) as a non-protein nitrogen source, replaces soybean meal in the first ratio. For a fattening period that lasted (6) months, during which the quantities of consumed fodder, the rates of live weight gain, and some characteristics of carcasses were calculated. The results showed that there were no significant differences between the experimental treatments in the rates of daily and total weight gain and the final weight of calves. Although the statistical analysis of the consumed feed was not conducted because the feeding was collective, no arithmetical difference was observed between the transactions in the daily consumed quantities of feed, which in the first treatment amounted to (5.836) kg of concentrated feed/day/calf and in the second treatment (5.768) kg. Concentrate feed /day/calf , and feed conversion rates did not differ among the experimental treatments. The statistical analysis also showed that there were no significant differences between the experimental treatments in the weight of the carcass and the dressing percentage.
