Abstract

Eighteen Beetal does in early lactation were randomly distributed into three groups of six goats. The first group was fed 125% (A), the second 100% (B) and a third 75% (C) of a digestible protein (DP) standard for sheep. Energy (TDN) level was constant in all three groups at 100% of the standard. A randomised block design was followed. Around mid-lactation (from the 7th to the 11th week), a metabolism trial was conducted to measure feed intake, nitrogen balance and milk production. Mean intakes (±s.e.) of dry matter (DM), DP and TDN were 81.5±3.1, 9.3±0.3 and 62.1±2.6 g/kg metabolic body weight (W0.75) respectively in treatment A, 87.7±3.7, 8.0±0.3 and 66.2±2.8 g/kg W0.75 in treatment B, and 86.4±5.2, 6.4±0.3 and 65.01±3.9 g/kg W0.75 in treatment C. There were no significant differences among the three treatments in DM and TDN intake, while DP intake was different (P<0.01). Requirements of total protein (TP) and DP for maintenance of lactating goats were 6.54 and 3.96 g/day per kg W0.75 respectively. For 100 g protein (N×6.38) secreted in milk the requirement was 186.97 g TP or 132.13 g DP.
