Digestibility and Digestive Tract Measurement of Wild Boar(Sus scrofa)

Digestibility of wild boar(Sus scrofa) weighing 53±2.3 kg and digestive tract characters of wild boar weighing 33~43 kg is studied,compared with that of a Chinese domesticate pig-Bamei.The results showed that daily diet intake of wild boar was siginificantly lower than that of Bamei(2.44±0.15 kg vs.3.43±0.28 kg)(P0.05),and it is the same case for quantity of daily digestive crude protein(CP)(0.231±0.126kg vs.0.309±0.084kg)(P0.05).However,digestibility for CP and utilized quantity of phosphorous(P) of wild boar were all significantly higher than those of Bamei(75.89±1.26% vs.72.3±0.45% and 27.67±1.91% vs.19.99±1.79%,respectively).Quantity of daily digestive crude fiber(0.059±0.028 kg) of wild boar and its digestibility were all significantly lower than those of Bamei.Large intestine length (3.36±0.38 m),large intestine capacity(5.91±1.04 L),stomach capacity(1.82±1.36 L) and small intestine length(14.15±0.31 L) were all extremely significantly lower than those of Bamei.(P0.01).
