Abstract

The influence of different supplement types on the performance and nutrient dynamics of goats stocked in woodlands is not known. The objective of this study was to evaluate the effect of supplement type on the performance and the concentration of fecal nutrients of nursing does and the performance of kids raised in woodlands. One group of goats (SG, 9 does; 18 kids) was allowed supplemental grazing in adjacent silvopasture plots for 3–4 h daily and another group (SF, 8 does; 15 kids) was supplemented with corn (0.5% of metabolic weight) and ad libitum hay. Vegetation samples were collected and analyzed for productivity and quality (crude protein, CP; acid detergent fiber, ADF; neutral detergent fiber, NDF). The quality of the hay (N, ADF, NDF) and fecal samples (N, P, Ca) was analyzed. The animals’ live weight, FAMACHA score, and body condition score were collected. The browsing height for does consuming woodland vegetation was measured. Data were analyzed using the GLM procedure, Mixed procedure, and MEANS procedure in SAS 9.4. SG does showed better FAMACHA scores vs. SF does (p < 0.05). Fecal N and ADF were greater (p < 0.0001) in SG does vs. SF does. The findings showed a better performance and greater concentration of fecal nutrients in SG does vs. SF does, suggesting grazing quality pastures is a better option than using feedstuffs to supplement nursing does in woodland.
