This study was conducted to evaluate the feeding value of jambo grass (Sorghum bicolour×Sorghum sudanefe) silage and mott grass (Pennisetum purpureum) silage as a replacement of conventional fodder (jambo grass) in the diet of lactating Nili buffaloes (Bubalus bubalis). Thirty early-lactating (45±4 days), multi-parous Nili buffaloes, ten in each group, were allotted to three experimental diets. Jambo grass and mott grass were ensiled with molasses (at 2% of fodder DM) in two trench silos for 30 days. The control diet (JG) contained 75% jambo grass while the other two diets contained 75% jambo grass silage (JGS) and 75% mott grass silage (MGS). The remaining 25% DM in each diet was supplied by concentrates. Diets were mixed daily and fed twice a day ad libitum for 120 days. Dry matter intake (DMI) was higher with the JG diet compared with JGS and MGS diets. However, DMI as % body weight did not differ significantly in buffaloes fed either fodder or silage based diets. Crude protein (CP), digestible CP and NDF intakes were significantly higher on JG compared with silage-based diets. Apparent total tract digestibilities of DM, CP and NDF were similar in buffaloes fed JG, JGS and MGS diets. Milk yield (4% FCM) was similar in buffaloes fed JG and silage based diets. Fat, total solids, solid not fat, CP, true protein and non-protein nitrogen content of milk were similar in buffaloes fed fodder or silage based diets. The present results indicated that jambo grass and mott grass ensiled with 2% molasses for 30 days could safely replace the conventional fresh grass fodder (75% DM) in the diet of lactating Nili buffaloes without affecting their milk yield.

Zusammenfassung Die freiwillige Aufnahme von Natriumhydroxyd‐behandelten Weizenstrohpellets beim Schaf. 1. Der Einfluß der Natriumhydroxydkonzentration Vier wachsende Schafe, die 54,2 ± 4,1 kg wogen, bekamen in einer 12wöchigen Versuchsperiode in einem 4X4 Latin Square Versuch pelletiertes Futter, das 70% Weizenstroh enthielt, welches mit 0, 2,4, 4,1 bzw. 5,6% NaOH behandelt worden war. Futter und Wasser wurde den Tieren ad libitum verabreicht. Die Aufnahmen von verdaulicher organischer Substanz waren 779, 1075, 1269 bzw. 1085 g pro Tag von diesem Futter. Die korrespondierenden Mengen von Natrium und Wasser waren 11,3, 25,1, 41,8 bzw. 47,7 g und 4,8, 6,5, 8,1 bzw. 8,3 Liter. Es wurde konkludiert, daß die Futteraufnahme — was das mit 5,6% NaOH behandelte Stroh betrifft — von der Natriummenge begrenzt wurde. Die Schafe vertrugen maximal pro kg0.75 Körpergewicht 2,2–2,4 g Natrium im Futter, wenn ihnen Wasser ad libitum verabreicht wurde.
