The Effects Of Drinking Formalin On The Intake Digestion And Metabolism By Lambs And Small Tail Han Sheep

In this experiment, the lambs (Experiment.1 and 2, the average weight are 14.3Kg and 24.1 Kg respectively, n=3) fed with their diets, almost made of concentrated feed. The Small Tail Han sheep (Experiment.3, the average weight is 54.3 Kg, n=5) fed with diet, almost made of corn straw. We study on the effects of drinking formalin on the intake, digestion and metabolism of lambs and SmallTail Han sheep. The results show that, drinking formalin can increase the intake of experimental animals, from 929.0±108.8 to 1329.2±269.0g/lamb/d(Experiment.1),from124.8±155.9to1701.1±465.9g/lamb/d(Experiment.2),andfrom1632.3±118.3to1746.4±201.2g/sheep/d(Experiment.3).the retention of Nitrogen increase,from16.01±2.87to21.45±0.24g/lamb/d(Experiment.1),from16.33±3.64to25.05±1.40g/lamb/d(Experiment.2), and from 9.39±3.02 to 12.82±2.70 g/sheep/d(Experiment.3) . The day of weight gain also increase, from 207.6±30.3 to 328.8±78.3g/lamb/d(Experiment.1), from 204.5±2.3 to 310.6±34.7 g/lamb/d (Experiment.2), and from 75.0±15.3 to 92.5±24.4 g/sheep/d(Experiment.3), but drinking formalin don't affect their diet digestibility significantly. This study shows that drinking formalin can increase the production ability by a big margin.
