Abstract

The objective of this study was to determine the effect of urea-molasses and di-calcium phosphate additives on silage quality and milk yield of cows. Hence, three types of silages were prepared from Napier fodder namely-Napier silage, urea and molasses added Napier silage (UMN); and di-calcium phosphate added Napier (DCPN) silage. These types of silage fed to the selected nine lactating Holstein-Friesian crossbred cows and divided into three groups considering three of each. Along with 5 kg of respective silages, ad-libitum rice straw and 3 kg concentrate mixture supplied to each group of cows. Physical attributes of all prepared silages were possessing characteristics of good quality silage. Dry matter content in UMN and DCPN silages were 1.67 and 1.01% higher than Napier silage. UMN silage had 1.59 and 2.33% lower ADF from Napier and DCPN silage, respectively. Again, 1.29% higher NH3-N presents in UMN silage than Napier silage. From 1st to 4th fortnight milk yield data it was found that 23.70, 23.19 and 27.06% milk production increased those cows received Napier, UMN and DCPN silage, respectively. Considering above these, it might be concluded that addition of di-calcium phosphate as additive during silage making would be beneficial for the dairy farmers. Asian Australas. J. Biosci.

添加不同添加剂对泌乳杂交奶牛青贮品质及产奶量的影响

本试验旨在研究尿素糖蜜和磷酸二钙添加剂对奶牛青贮品质和产奶量的影响。因此，以纳皮尔饲料为原料制备纳皮尔青贮、尿素和添加纳皮尔青贮糖蜜(UMN) 3种青贮;磷酸二钙添加纳皮尔青贮。选取9头泌乳荷斯泰因-弗里西亚杂交奶牛饲喂这些青贮饲料，每组3头。每组奶牛分别饲喂青贮料5公斤、秸秆和精料混合物3公斤。各青贮物性指标均具有优质青贮的特点。UMN和DCPN青贮的干物质含量分别比Napier青贮高1.67%和1.01%。UMN青贮的ADF分别比Napier和DCPN青贮低1.59%和2.33%。同样，UMN青贮的NH3-N比Napier青贮高1.29%。从第1 ~ 4周产奶量数据看，饲喂Napier、UMN和DCPN青贮的奶牛产奶量分别提高23.70%、23.19%和27.06%。综上所述，在青贮过程中添加磷酸二钙添加剂对奶农有利。亚洲Australas。j .
