Abstract

Effects of creep grazing and stocking rate on diet selection and nutritive value of Spanish does with Boer × Spanish kids and Boer × Spanish does with 3/4 Boer–1/4 Spanish kids were determined in ten 0.4-ha grass/forb pastures of the American Institute for Goat Research of Langston University, Langston, Oklahoma, USA. There were four treatments, three involving stocking rate and one creep grazing, with two animal groups per treatment. Groups had 4 does with 8 kids for the low SR (L), 6 does with 12 kids for a moderate SR (M), and 8 does with 16 kids for both the high SR (H) and creep grazing treatments (C). Kids on the C treatment also had access to similar 0.4-ha pastures but that contained the tree legume mimosa (Albizia julibrissin Durazz) planted in rows. This species was used because of the high nutritive value of leaves (23.9% CP, 22.9% NDF, 5.7% ADL, and 91.8% in vitro true DM digestibility (IVDMD)) and ready consumption by goats. Each pasture consisted of four equal-size paddocks that were rotationally grazed twice during the 76-day study. A direct observation and simulation method was applied to determine botanical composition and nutritive value of the diet selected by does and kids. There were no effects (P > 0.05) of stocking rate or animal type on the diet selected. Diets were higher (P
