Resumo
In order to evaluate the effects of adding
water to mash diets on nutrients and energy
digestibility, performance, water intake and quality
of pig excrement at the growing phase, 12 barrows
with initial weight of 44.0 ± 3.1 kg were used. For
the digestibility trial, the animals were distributed
into a randomized block design based on their
weight. For the performance test, 18 barrows and
18 females with initial weight of 33.0 ± 3.5 kg were
distributed into a completely randomized design.
All animals were hybrids lineage Agroceres Pic.
Treatment one consisted of a diet formulated to
meet the animals' requirement. Treatments two
and three consisted the following of water:feed
ration (kg:kg) 1:1 and 2:1. There was no statistical
difference among treatments for the coefficients
of dry matter digestibility, gross energy, ether
extract, calcium and phosphorus, and for the
variables of performance, moisture, and fecal
nitrogen and phosphorus. In absolute terms, the
reduction of fresh water intake and of phosphorus
excretion for animals receiving liquid diet is 17.81 %
and 15.40 %, respectively. The addition of water
to pig diets at growing phase does not influence
the nutrients digestibility and the performance of
the animals when they are fed twice a day.
