English Abstract
This experiment was conducted to study the effect of molasses as sorghum replacer on the performance, carcass yield and meat quality of Sudan Baladi rabbitlets. Forty five, entire male Baladi rabbits, 40-45 days old were assigned randomly to five groups, offered five experimental diets (21 % CP, 3Mcal), with a control group A without molasses, 30, 40, 50 and 60 % molasses for test groups B, C, D and E respectively, replacing Dura (60 %) in the ration. The rabbits were fed their respective diets for 56 days.
Data on feed intake was taken daily and liveweight weekly.
The rabbits were slaughtered terminally and their carcasses were analyzed and the meat was evaluated chemically. Final liveweights, average daily gains and total gains (g) were not significantly influenced (p>0.05) by the dietary treatment.
Group B daily gain (8.43±1.98) and total gain (474.57±111.32) were higher and group E was lower for both parameters.
Daily intake (g) of groups A, B and C were higher (p<0.05) than groups D and E (28.73±1.60).
No statistical difference (p>0.05) between treatment groups on FCR but group B appeared to be more efficient feed converter (3.97±1.19) than other treatment groups.
No significant (p>0.05) differences were observed on most percent slaughter and carcass values.
Carcass cuts (except for the shoulder and foreleg) were not significantly (p>0.05) influenced by treatments.
Treatment effect was not significant (p>0.05) in all values of carcass yield.
Group D was highest than the other groups on the mean values of hot carcass % (59.96±1.93) while group C was lowest one on mean values of hot carcass % (55.71±3.30).
Treatment effect on commercial cuts was not significant (p>0.05), but there was a significant (p<0.05) treatment effect in shoulder and foreleg, total lean and total bone. Total lean of group D (503.50±1.56) was highest than groups B, C, A and E (412.6±35.50) in descending order.
Total bone of group D was highest (122.40±1.56) than the other treatment groups.
Meat: bone ratio ranged 3.7 : 1 for group B (lowest) to 4.3:1 for group C (highest).
Lean ultimate pH range was 6.00-6.20, and moisture was 61.73-67.66 and 0.80-0.90 % ash.
On the other hand minerals content of the rabbit meat varied between 0.081-0.086 Ca, 1.20-1.40 P, 0.0050-0.0059 Fe، 0.041-0.059 Cu, 0.17-0.20 Na and 0.46-0.54 K.
Use of molasses in replacement of cereal. grain in rabbit rations can be adopted 30-60 % of the ration by weight giving similar performance values to the conventional rations.
The Baladi type rabbit is a good converter of feed and it actually parallels all other specialized meat rabbit types.
Growth rates are negatively corelated with molasses replacement values.
