  • Goats have been subjected to production schemes with increasing levels of intensity, which imply space limitations and a decrease or even removal of the possibility to show behaviours they have developed during their evolution. The objectives of the present study were to: 1) evaluate the effect of environmental enrichment on welfare and behaviour and 2) find alternatives of handling through environmental enrichment in Murciano-Granadina suckling dairy goat kids in confinement. Two treatments, enriched and non-enriched, were the randomly assigned to 7-day-old dairy goat kids (n=96), with four replications of each treatment (n=12 for each replica). Enrichment elements were feeding on high, straw bales, concrete blocks and bricks. Observations were carried out by video (132 h), during 3 periods of 11 days each, during the 90 days of the experiment. The behaviours studied were: ingestion, body care, locomotion, exploration, rest-sleep and agonistic. Data were analyzed using a non-parametric test (Mann-Whitney) for comparisons between treatment groups The enriched compared to the non-enriched kids carried out more ingestive (2.55 ± 3.01 vs. 0.34 ± 0.52), body care (1.62 ± 1.56 vs. 1.16 ± 1.73), locomotion (8.43 ± 6.97 vs. 3.31 ± 4.67), exploration (2.83 ± 2.24 vs. 1.32 ± 1.67) and rest-sleep (3.81 ± 2.79 vs. 2.30 ± 2.10) (P< 0.01). The difference in agonistic behaviour (0.66 ± 0.97 vs. 0.98 ± 1.68) was not significant (P>0.05). Exploration in non-enriched goats was directed to the elements of the pens, adversely affecting facilities. This study suggests that simple and low cost changes in the environment have significant effects in the behaviour and perhaps the welfare of kids in confinement
