| Popis: | We hypothesized that diet choice of mixed-breed goats on xerophytic shrubland of northern Mexico depends on their milk yield potential. During winter and spring (dry season), milk yield was recorded and forage samples were collected weekly. Goats were separated into a medium (MP; n = 20) or low-milk yielding groups (LP; n = 20). Total milk yield for 105 d lactation was 45.2 ± 12.5 and 20.7 ± 5.2 L for MP and LP goats, respectively. Dam bodyweight was positively related to milk yield (P |
