Abstract

The objective of this experiment was to investigate the effects of forage species and feeding systems on ruminal fermentation, microbiota (Butyrivibrio fibrisolvens, Fibrobacter succinogenes and total bacteria) and conjugated linoleic acid (CLA) concentration of milk in dairy goats. Twenty female crossbred Saanen lactating goats (~35 ± 3.0 kg bodyweight) in early to mid-lactation stage were assigned to a 45-day completely randomised-design feeding experiment, with the following four forage (roughage) treatments: cut-and-carry grass (CG), grazing of grass (GG), cut-and-carry leucaena (CL) and grazing of leucaena (GL; n = 5). All animals were given concentrate equivalent to 1.5% of their bodyweight. The grass used in the study was napier Pak Chong 1 grass (Pennisetum purpureum × Pennisetum americanum hybrid). The results showed that irrespective of the type of forage, grazing goats (GG and GL) had a higher (P < 0.05) forage intake and, thus, total dry-matter and crude-protein intakes than did those fed indoors (CG and CL). However, the intake of C18:2n6 and particularly of C18:3n3 was generally higher for grass-fed goats than for leucaena-fed goats. Treatments did not exert significant differences on rumen fermentation characteristics. However, the populations of B. fibrisolvens, F. succinogenes and total bacteria were significantly (P < 0.05) higher in grazing goats (GG and GL) than in their counterparts fed with the cut-and-carry system (CG and CL). Goats in the grazing system also had a higher (P < 0.05) milk yield, and milk fat, c9, t11 CLA and omega-3 fatty acid concentrations than did those in the cut-and-carry system and only grazing goats produced detectable levels of t10, c12 CLA in milk. Putting the above together, it can be concluded that allowing dairy goats to outdoor grazing stimulates a higher forage intake, including that of C18:2n6 and C18:3n3, as well as enhancing population of B. fibrisolvens (involved in the synthesis of milk CLA), resulting in a higher milk yield, and enhances c9, t11 and t10, c12 CLA in goat milk.
