TABLE OF NUTRIENT REQUIREMENTS

The nutrient requirements presented in Table 1 can be used to formulate diets for the different classes and categories of goats by proper use of available feedstuffs. The table lists nutrient requirements for maintenance at different levels of muscular activity and additional requirements for growth, pregnancy, lactation, and mohair production. The daily energy requirements for maintenance are 101.38 kcal ME/Wkg0.75 [1 kg TDN=4.409 Mcal DE (Garrett et al., 1959) or 76 DE=62 ME=35 NE; protein requirements are related to energy needs as follows: 22 g DP or 32 g TP per Mcal DE]. The energy requirement for growth is 7.25 kcal ME/g of gain. Goat kids at very young ages may not be able to consume the suggested required quantities of DM. Similar situations can exist with high-producing dairy goats, but intakes of more than 5 percent of body weight have been reported (Haenlein, 1978). The energy requirements per kg FCM at 4 percent are 1246.12 kcal ME; and a 0.5 percent fat change in 4 percent FCM is 16.28 kcal ME. Additional requirements for mohair production are also presented. Details on Table 1 are discussed in Chapter 2.
