Abstract
This behavioral study analyzes the relationship between water intake and growth performance in pre-weaned piglets. Growth is paramount in pork production, and maximizing growth in weaned piglets has been thoroughly researched. However, one crucial aspect of growth is often overlooked: water, especially in neonatal piglets. Therefore, this study aimed to determine if there is a positive relationship between water intake and performance in pre-weaned piglets by observing different behaviors. Weights were recorded at birth, after 7-10 days, and at weaning. Piglets were observed three times a day, in the morning, afternoon, and evening, for 21 days via scan sampling. Observation periods lasted 15 minutes, and a variety of behaviors were documented, with an emphasis on water visits and drinking. The impact of observation day and observation time on drinking behavior was analyzed via chi-square analysis and was significant for both traits (P < 0.0001), though results regarding observation day were ambiguous. The relationship between drinking behavior and body weights was analyzed via a mixed model analysis, and statistical significance was found between drinking and Day 21 weights (P = 0.0012). Any changes in drinking behaviors impacting weight gain can positively impact pork production. Even a small increase in growth during the pre-weaning phase could mean greater profits for producers and more pork available for consumption. Increasing water availability and consumption by neonatal piglets can also have a positive impact on overall animal welfare.
