摘要

The objective of the present study was to determine the pasture intake of European wild boar and domestic pigs throughout their growth period (from 60 to 207 days of age). The proportion of time that each animal type spent grazing was also determined. Twelve 60-day-old pure-bred European wild boar (six castrated males and six females, average live-weight (卤s.e.m.) 6路8 卤 0路37 kg) and 12 70-day-old domestic pigs (Large White 脳 Landrace, six castrated males and six females, average live-weight [ 卤 s.e.m.] 24路1 卤 0路66 kg) were used in the study. Each day during the study, the animals grazed from 08路00 until 16路00 h, after which they had ad-libitum access to a supplemental diet for 1 h. Every 14 days throughout the study (a total of ten determinations), the pasture consumption was determined as the difference between the pasture dry matter (DM) availability pre- and post-grazing. The supplemental diet consumption was also determined. Three times during the study (age of animals 85, 140 and 198 days), the behaviour of each animal was observed over four consecutive days while grazing. When considered on a metabolic bodyweight basis, the pasture consumption of the European wild boar was greater than that in the domestic pigs. Approximately 0路20 of the total DM intake by the wild boar was pasture, whereas only 0路10 of the total DM intake by the domestic pigs was pasture. However, domestic pigs consumed a greater quantity of supplemental diet than the wild boar. The wild boar obtained 0路20 of their total daily dietary apparent energy intake from pasture, compared with 0路07 in the domestic pigs. Wild boar were more active during 8-h grazing periods spending 0路54 of their time grazing or moving around, compared with 0路32 of the time in domestic pigs.
