The animals were fed ad libitum for 9. The results show that molasses can be included in fattening diets up to a maximum level of 3. There was little difference in feedlot performance between steers and heifers. The practice of fattening cattle on maize- based high energy diets has become uneconomical due mainly to the high cost of maize grain relative to beef producer prices in Zimbabwe. In an earlier trial a less expensive diet than the conventional maize- based fattening diet was achieved by using cane molasses, a by- product of the sugar industry (Chakanyuka, Sibanda, Grant and Mlilo, 1. Molasses was incorporated into this diet at the rate of about 2. However, since it is cheaper than maize grain, as much of it as possible should be included in fattening diets. It was therefore necessary to determine the maximum level of molasses which could be used in cattle fattening diets without adversely affecting performance. This study was carried out to investigate the relationship between the level of molasses in the diet and the performance in feedlot of both steers and heifers over a 9. A total of 1. 00 eighteen month old steers and heifers, 5. Sussex x Africaner and the other 5. Hereford x Mashona x Sussex crossbreds, with an average starved body weight of about 2. Animals of each sex were divided into 5 equal groups of 1. A 6th group of 1. Table 1. Formulation and chemical composition (% air fresh) of cattle fattening diets. The 6 animals in each sub- group were housed in one pen and group- fed ad libitum for a period of 9. The animals were weighed fortnightly and food intake was calculated weekly. At the end of the feeding period the animals were slaughtered and carcass measurements taken. There was no significant difference between the steers and heifers, although the heifers had marginally smaller body weight changes than the steers. There was a significant (P< 0. Body weight changes for the animals on 1. P< 0. 0. 5) than the zero and 4. The 4. 0 per cent molasses diet gave the lowest body weight change but this was not significantly lower than that of the conventional zero molasses diet. Initial body weight as a covariate of body weight change and the interaction between sex and diet were not important. Regression equations (1) and (2) were used for steers and heifers, respectively. CW = 1. 33. 2 ln BW - 6. The carcass weight changes of heifers and steers were similar (Table 3). There was a significant (P< 0. The mean carcass weight change of the conventional zero molasses animals was lower (P< 0. The diets containing 1. P< 0. 0. 5) than those of the zero and 4. The highest mean carcass weight changes were achieved by the animals on the 2. As with body weight gains, initial body weight as a covariate of carcass weight change and interaction between sex and level of molasses was not important. The efficiency of food conversion for body and carcass weight gain was the same for steers and heifers (Table 4). The efficiency of conversion for body weight gain exhibited a linear relationship with the level of molasses in the diet as the rate of decrease continued to increase with higher levels of molasses, but the decline became very marked (P< 0. The rate of decrease in efficiency of food- conversion decreased as the level of molasses increased. However, there was no significant difference between the efficiency of food- conversion for carcass weight gains of the zero, 1. The 4. 0 per cent molasses diet produced a significantly (P< 0. There was no interaction between sex and diets and similarly initial body weight as a covariate of efficiency of food- conversion for carcass and body weight gain was not important. Body weight changes (kg) of cattle fattened on diets with different levels of molasses. Carcass weight changes (kg) of cattle fattened on diets with different levels of molasses. Total food intake (kg/head, air- fresh) and efficiency of food- conversion for body weight gain (kg food/kg body weight gain) and carcass weight gain (kg of food/kg carcass weight gain) of cattle fattened on diets with different levels of molasses. The fleshing index is based on the ratio of carcass weight to length. Classes 1 and 2 depict animals with adequate fat cover, class 3 would be underfat and class 9 overfat. The last two classes carry some form of penalty. Overall the highest fleshing grades were obtained with the 2. The fleshing grades for heifers fell more markedly than those for steers at molasses levels higher than 2. There was little difference between the treatments in fat grades, although heifers tended to be fatter than steers. The results of this study agree with earlier trials carried out in this laboratory (Chakanyuka et al. Lishman 1. 96. 7; Elliot and O'Donovan 1. Van Niekerk 1. 98. They indicated that molasses can make up to 3. This confirms the results of the earlier work in which a diet containing 2. Chakanyuka et al. This would mean that animals on molasses diets would have fewer digestive problems and would take a shorter time to adapt to the diets. In the present trial in took up to three weeks before the animals on the conventional zero molasses diet stopped scouring, while those on the molasses diets did not scour at all. On as fed basis all molasses diets produced lower efficiency of food- conversion, a finding which confirms earlier studies in this country (Elliot and O'Donovan 1. Chakanyuka et al. Van Niekerk and Voges 1. Van Niekerk 1. 98. Carcass grades (%) of cattle fattened on diets with different levels of molasses. Therefore the ME in the diets containing 1. These results are in agreement with the last trials when the ME in the diet containing 2. Chakanyuka et al. While the conventional diet may exhibit a higher efficiency of food- conversion the returns from it are likely to be lower due to the resultant smaller carcass and lower grades. The results of the present trial show that there was no difference between steers and heifers in efficiency of food- conversion for carcass weight gain. However, the fat grades indicate that heifers may tend to get fatter. It may be advisable to slaughter heifers earlier than steers of similar size. Molasses can be included in fattening diets by up to 3. This would result in relatively cheaper diets, provided the molasses was available and continued to be cheaper than maize grain. These results apply to both steers and heifers, although heifers may need to be slaughtered earlier to prevent them from getting overly fat.
