“…In addition, the higher water intake caused by diets with cactus cladodes represents one of the reasons for the low DM content in the faeces of animals that receive this feed. Silva et al (2021a), observed strong and significant correlation between faecal dry matter and water intake (r = − 0.91; P = 0.001), so that these two variables were negatively related.…”

“…In Brazil, cactus cladodes are used as animal feed, especially during periods of drought, configuring a strategic forage resource to livestock in drylands (Pessoa et al ., 2020; Rocha Filho et al ., 2021). Regardless of the genus, Opuntia or Nopalea , the cactus cladodes have a high metabolizable energy content (2.29–2.39 Mcal/kg dry matter) and represent an important source of water (Rocha Filho et al ., 2021; Silva et al ., 2021 a , 2021b).…”

The water balance and urinary parameters of lambs fed diets containing cactus cladodes varieties were evaluated. Thirty-six uncastrated male Santa Inês lambs (22.0 ± 2.9 kg initial body weight) were distributed in a completely randomized design, with three treatments and 12 replicates. The animals were fed a control diet (Tifton-85 hay as exclusive roughage), Miúda or Orelha de Elefante Mexicana (OEM) cactus-based diets. Urine samples were collected 45 days after the introduction of the tested diets, and voluntary water intake was measured over 10 days, during the experimental period. Diets containing Miúda or OEM cactus caused a reduction of 68.35 and 77.03% in voluntary water intake, respectively. In addition, the Miúda cactus cladodes caused urinary alkalinization (pH = 8.14) and reduction in the urinary excretion index (UEI) and on the fractional excretion rate (FER) of total calcium (Ca). The diets with OEM cactus cladodes caused higher oxalates intake (6.21 g/day) and increase in urinary volume. Regardless of the variety, there was a reduction in the urinary concentrations of urea, creatinine, total proteins, Ca, phosphorus (P), UEI of urea and P, as well as in FER of P, compared to the control diet. Urinary Mg content and UEI of uric acid and Mg increased and FER of P decreased by diets supplemented with different varieties of cactus cladodes. In conclusion, the cactus cladodes increased water intake and retention, and diuresis in lambs, altered urine parameters, without compromising kidney function.
