Effect of lasalocid addition in diet on growth performance, digestibility, carcass traits, and blood constituents in growing rabbits

Zanaty G.A.A., Abou-Zeid A.E., Amber K.H.

Sixty-four New Zealand white rabbits about 5 weeks old were allotted to four groups. Treatments consisted of two levels of crude protein High (18.1 per cent) and Low (14.2 per cent). Each level was tested with and without Lasalocid at 40 mg/kg diet. During 6 weeks, live weight and feed intake were recorded weekly. At the last week the faeces and urine were collected to determine the apparent digestibility and nitrogen balance. Six animals from each group were sacrificed to study carcass characteristics. Final body weight, growth rate and live weight gain were improved by (p £ 0.001) as a result to increase protein level and lasalocid addition. DM intake (g/d) was decreased (p £ 0.001) by 7.8g when protein level increased and 2.2 g by lasalocid supplemented. Also feed conversion rate (g/g) was improved (p £ 0.001) by 1.13 and 0.31 per cent due to increase protein level and lasalocid addition respectively. The DM, EE and CF digestibility were improved significantly by 3.9, 3.5 and 5.9 per cent respectively when protein level increased in diets the same trend observed with lasalocid supplementation 1.8, 2.4 and 1.0 per cent with lasalocide supplemention. The Cp digestability was improved by (p £ 0.001) by 3.7 per cent and 3.4 per cent due to increase protein level and lasalocid addition. Dressing per cent was increased (p £ 0.01) while bone per cent was decreased (p £ 0.05) when protein level increased.
