Cereal pastures are a crucial source of forage to reduce grazing pressure on shrublands in the Mediterranean basin. This study aimed at investigating the grazing preferences and behaviours of goats with different genotypes, when a grazing area of shrubland (0.18 ha), which was composed of 88% shrubs, 10% herbaceous species and 2% footpath and wheat (Triticum aestivum L.) pasture (0.20 ha) were offered together. Twelve lactating mature (in 2007) and 15 non-lactating yearling goats (in 2008) of three genotypes (Gokceada, Maltese and Turkish Saanen) were used. The study was carried out for 45 days during the months of April and May. Animals stayed in the pasture for 8 h daily. No roughage or concentrate was offered. Grazing, lying, standing and ruminating behaviours were recorded at 10-min intervals, whereas bipedal stance and walking behaviours were continuously monitored by observers. Mature goats spent one-third and yearling goats spent half of their time in the shrubs. The frequency of preferences to pasture types differed among mature goat genotypes (P ≤ 0.05), but not among the yearling goats (P > 0.05). Grazing of wheat pasture by Gokceada, of herbaceous plants in the shrubland by Maltese and of shrubs by Turkish Saanen goats were more prominent (P ≤ 0.05). In conclusion, goats gave priority to wheat pasture and grazing preferences and behaviours differed by genotypes. Turkish Saanen goats tended to show more bipedal stance behaviour than the other genotypes. However, there were high individual variations within genotype and age groups.

This study aimed at identifying changes in natural pastures during the grazing season and investigating the effects of these changes on pasture feeding potential for high yielding dairy goats. During the study, 12 dairy goats were grazed on a 1.5 ha natural pasture for three months from April to June in 2003, 2004 and 2005. The goats were fed 0.5 kg/day of concentrate as a supplement during the grazing season. Botanical composition, herbage production and intake, crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of the pasture were determined. Live weight, milk yield, milk dry matter (DM) and fat content of the goats were monitored. The data were analyzed using a linear model, which evaluated the effects of grazing seasons in each year. Based on the three-year average, 87% of pasture was herbaceous plants and the remaining was shrubs in DM basis with Cistus creticus, Quercus ithaburensis, Pistacia atlantica and Asparagus acutifolius being the major shrub species. The herbage yield in June was significantly lower than in other months in all years (P = 0.001). In all experimental years, the CP content of the pasture decreased but the structural carbohydrates increased as the grazing season proceeded. While live weight was not affected by grazing periods except for 2004 (P = 0.001), milk yield significantly decreased with advancing grazing period (P = 0.001). The results of the present study indicate that natural pasture has a supportive effect in April and May on the milk yield of lactating goats which are in mid-lactation, and suggested that supplementary feeding is required in consecutive grazing periods.
