Effect of supplementation of cotton seed oil and its bypass fat on nutrient intake, utilization and growth in goat kids

A trial was conducted to study the effect of supplementing cotton seed oil and its bypass fat on nutrient utilisation and growth in kids. Eighteen male Beetal kids (3 months-old) were divided into three group viz., T₁ (control): offered basal diet without any supplementation. T₂ : offered basal diet and supplemented with cottonseed oil @ 2% of total dry matter intake (DMI) and T₃ : offered basal diet and supplemented bypass fat (prepared from cottonseed oil) @ 2% of total DMI. The results showed that ether extract digestibility (%) was significantly (P<0.05) increased in T₂ (75.81±0.34) and T₃ (75.03±0.23) as compared to control (73.50±0.33). Dry matter and nitrogen free extract digestibility (%) were increased significantly (P<0.05) in T₃ (66.97±0.29 and 71.01±0.40) as compared to T₁ (65.41±0.33 and 68.76±0.54). Ca balance (g/d) was significantly (P<0.05) increased in T₃ (2.95±0.11) as compared to T₁ (1.93±0.13) and T₂ (1.98±0.08). Average daily gains of kids (g) were significantly (P<0.05) increased for both the supplemented groups T₂ (102.99±1.09) and T₃ (114.24± 0.85) than control (94.79±0.37). The feed conversion ratio was significantly (P<0.05) increased in bypass fat supplemented (8.73± 0.25) than control (10.01± 0.35). It can be concluded that supplementation of bypass fat significantly increased the nutrient digestibility, average daily gain and feed efficiency in kids.
