Abstract:

【Objective】 The aim of this study was to explore the effects of the total mixed ration (TMR) based on the whole-plant corn silage on the production performance and economic profit of fattening sheep of different varieties and therefore offer theoretical support to the application of the whole-plant corn silage and healthy sheep production. 【Method】 Nutritional composition and rumen degradation characteristics of the whole-plant corn before and after ensiling were evaluated by in Sacco method. Four varieties of 3-month-old healthy male lambs (breast-milk weaned) with similar body weight (27.6±1.7) kg, were selected. There were the following four treatments accordingly: Small-Tail Han (SH), “Dorper×Small-Tail Han” F1 (DH), “Mongolia×Han” F1 (MH) and “Dorper×Wadi” F1 (DW). Each treatment had 30 lambs, which were divided into 3 replications. Forage to concentrate ratio of TMR is 25:75. There was an adaptation period of 10 days followed by an experimental period of 80 days, measuring the growth performance and slaughtering performance. 【Result】 Comparing to the whole-plant corn before ensiling, the silage did not have different content of crude protein (CP) (P>0.05) but owned greater DM, OM and rapidly degraded fraction (a) (P<0.01) and lower NDF, ADF and effective degradation rate (ED) (P<0.001). There was a tendency of higher DMI with hybrid sheep than with SH (0.05<P<0.1). The average daily gain (ADG), feed conversion ratio (FCR), carcass weight, neat weight, dressing percentage, neat percentage and neat percentage expressed in relation to carcass weight of DH and DW sheep were significantly higher than those of SH sheep (P<0.05). There was no significant difference in feed cost among all groups (P>0.05). The net meat gain, meat production efficiency and economic profit of DH and DW sheep were significantly higher than those of SH and MH sheep (P<0.01). 【Conclusion】 The whole-plant corn silage was suitable for use as the main feed source of TMR for fattening sheep, and all different breeds of sheep showed an expected production performance. The DH and DW hybrid sheep had a higher production performance and economic profit than that of SH sheep and MH hybrid sheep. However, there was no difference in production between SH and MH crossbred sheep. Therefore, DH and DW hybrid sheep were more suitable as fattening breeds in Huang-Huai-Hai farming area.
