“…Water disappearance (Table 2) only considers the water disappeared at the drinker level and does not distinguish what was ingested from what was wasted. The results measured for this variable are consistent with those found by Li et al (2005), Tavares et al (2014), and Rivest et al (2015) (7.31, 7.72, and 8.30 L/animal respectively), who also evaluated WD in pigs in the growing and finishing phases. The average ratio between WD and DMI was 3.43, which demonstrates the existence of the interaction between these variables.…”

“…Although there are studies that have evaluated the water intake of growing-finishing pigs (Li et al, 2005;Andersen et al, 2014;Tavares et al, 2014;Maselyne et al, 2016), the interaction of water disappearance with environmental variables and nutrient intake in natural conditions has still not been adequately explored. The objective of this study was to measure the disappearance and pattern of water intake, estimate water wasted, and generate information about the daily behaviour of water intake of pigs in the growing and finishing phases.…”

The objective of this study was to measure the water disappearance in the drinker and the pattern of daily water intake and estimate the amount of water wasted in pig production. The study will also generate information about the daily behaviour of water intake of pigs in the growing and finishing phases. Sixty male pigs with an average initial weight of 44.43 kg subjected to immunocastration were used. Animals received feed and water ad libitum. The animal-performance data, temperature and humidity, and feed and water intake behaviour were collected in real time during the entire experimental period, while water volume consumed was measured daily. The average water disappearance (WD) was 7.98 L, which increased during the studied period, and 29.07% of this corresponds to the estimated water wasted. The daily WD behaviour revealed an increasing pattern throughout the day for growing and finishing periods, with the registered peak at 16:00 and 15:00 h and intake of 6.24 and 9.48 L, respectively. The time spent drinking (TSD) and number of drinker visits (NDV) also showed a peak in the afternoon: 13:00 and 17:00 h for growing and finishing phases, respectively. The TSD was 282.73 and 268.36 s, and the NDV values were 16.13 and 13.84 for growing and finishing phases, respectively. The results demonstrated an increasing pattern during the animal housing period in WD that is proportional to dry matter intake and body weight, and the water wasted represents a significant portion of WD. The daily pattern of WD, TSD, and NDV increase during the total and growing periods, presenting peak activity at 13:00 h. During the finishing phase, TSD and NDV present a pattern similar to the growing phase, but the peak occurs in the last hour of the day.

“…Accumulation and distribution of copper and zinc in soils following the application of pig slurry for three to thirty years in a microwatershed of southern Brazil Rafael The state of Santa Catarina contains the largest pig herd in Brazil (ICEPA 2013), with 8,000,000 animals generating an average of 69,000,000 m 3 of slurry yr -1 (Oliveira 1993;Tavares et al 2014). However, because the farms in this state only cover a small land area of 15-60 ha and the areas suitable for agriculture are limited, an average of 270 m 3 of slurry ha -1 is applied to the soil each year (Couto et al 2010).…”
