Timing of supplementation on intake and grazing behavior dairy cows.

The objective was to evaluate the response of New Zealand Holstein cows to concentrate supplementation at contrasting times of the day on herbage intake and ingestive behavior. Two experiments were conducted in winter and spring-summer in a grazing dairy production system of Medicago sativa L. with Dactylis glomerata L.

Herbage intake of dairy cows in mixed sequential grazing with breeding ewes as followers.

This study aimed to evaluate the hypothesis that mixed sequential grazing of dairy cows and breeding ewes is beneficial. During the seasons of spring-summer 2013 and autumn-winter 2013-2014, 12 (spring-summer) and 16 (autumn-winter) Holstein Friesian cows and 24 gestating (spring-summer) and lactating (autumn-winter) Pelibuey ewes grazed on six (spring-summer) and nine (autumn-winter) paddocks of alfalfa and orchard grass mixed pastures. The treatments "single species cow grazing" (CowG) and "mixed sequential grazing with ewes as followers of cows" (MixG) were evaluated, under a completely randomized design with two replicates per paddock.
