| 總結: | The objective of the present work was to investigate if the practice of a dry-off period in goats maintained under grazing conditions, increases milk yield and therefore the quantity of its compounds. In goats without dry-off, females were hand milked until parturition (SPS; n = 9). Hand milking of goats from dry-off period was stopped 50 days prior occurrence of parturition (CPS; n = 11). We used a factorial design with a lineal model with fixed effects to compare milk yield and quantity of its main compounds, in response to the treatment, time, and time × treatment interaction. There was a treatment effect on milk yield during lactation, with higher values in CPS group than SPS group (P<0.001). In the same way, the quantity of milk compounds was influenced by the treatment (P<0.001). In conclusion, the practice of the dry period in goats under grazing conditions, increase milk production during subsequent lactation and therefore the quantity of its components. |
