“…These data differ from what was found for cattle (Mendes Neto et al, 2007) that were fed with different percentages of citrus pulp. Analysis of the rumination data according to the diet provided showed that the concentrate-rich diets led the sheep to ruminate more during the day, in a similar way to what has been observed among cattle and goats (Beauchemin, 1991;Desnoyers et al, 2009), and inversely to what has been observed among grazing sheep, which mainly ruminate and rest during darkness (Lin et al 2011).…”

In this study we examined the effects of different feed concentrates on sheep behaviour. Our hypothesis was that citric pulp would stimulate rumination and be capable of replacing other concentrates traditionally used for feeding in confinement, to reduce the risk of urolithiasis. Ten adult Santa Inês sheep were distributed in a Latin square with five different diets, one control diet with 80% hay and 20% commercial feed and four diets containing 30% coast-cross hay and 70% of the following concentrates: pelleted citrus pulp, citrus pulp meal, cornmeal or wheat bran. After 21d of adaptation to each one of the five diets, the sheep were visually monitored for 24 h at 3 min intervals to record the time spent ruminating, time spent eating and time spent resting; the animals' positions (standing or lying down) were also noted. Daytime was considered to be from 06:00h to 18:00h. The data were evaluated using ANOVA, with Tukey post-hoc test or throughout Two-sample T test for circadian and position assessment. Citrus pulp diets resulted in time spent ruminating similar to the control diet (601, 590 and 669 min, respectively), but greater (P<0.05) than the cornmeal group (421min), which showed that citrus pulp generated effective rumination. The estimated saliva production in the control diet (26L) was greater than in the other groups, and was greater in the citrus pulp groups (24L/d) than cornmeal (21L/d). Feeding with cornmeal led to shorter time spent eating and time spent ruminating than all other diets. The sheep had higher time spent resting at night when fed concentrates (P<0.05). For all diets, about 90% of the time spent ruminating occurred with the animals lying down. Pelleted citrus pulp, citrus pulp meal and to a lesser degree wheat bran, led to adequate time spent ruminating. The use of citrus pulp can act as a preventive management measure to reduce the incidence of urolithiasis in sheep flocks.Keywords: feed behaviour, citric pulp, rumination, urolithiasis, cornmeal Palavras-chave: comportamento alimentar, polpa cítrica, ruminação, urolitíase, fubá de milho RESUMO

“…This may be explained by the longer time spent ruminating that sheep exhibit, compared with cattle, thereby favouring greater dispersal of the results and, consequently, a higher coefficient of variation for behaviour among animals consuming a diet similar to that of dairy cattle (Mendes Neto et al, 2007).…”

“…Through the observation of feeding duration and efficiency, the evaluation of feeding behavior enables us to better understand the digestion of foods TREVISAN et al, 2005), including utilization efficiency, absorption efficiency, and rumination conditions (MENDES NETO et al, 2007). Thus, the present study was conducted to evaluate the feeding behavior of sheep fed corn silage diets with different levels of PKM.…”

In order to evaluate the feeding behavior of sheep fed with diets containing different levels of palm kernel meal (PKM) substituted for corn silage, a metabolic assay was performed on 20 ewes (5 treatments × 4 replicates) over 25 d. The animals received corn silage diets with the addition of increasing levels of PKM (0, 15, 30, 45, and 60%). The following parameters were evaluated: dry matter (DM) intake, neutral detergent fiber (NDF) intake, feeding time, rumination time, idle time, number of merycism mastications per bolus, time spent ruminating each bolus, DM and NDF per bolus, number of ruminated boluses per day, feeding and rumination efficiency, total chewing time, and number of merycism mastications per day. The daily intake of both DM and NDF increased linearly (P < 0.05), and when sheep were fed diets of at least 43.18 and 39.15% PKM, respectively, the consumption values were significantly different than when sheep were fed diets with 0% PKM (P < 0.05). In contrast, feeding time declined linearly, and in response to diets with at least 28.05% PKM, the sheep exhibited significantly different feeding times from those of sheep fed 0% PKM, with a reduction of 0.0613 percentage points per 1% increase in PKM. Idle time, rumination time, and rumination time per bolus each exhibited quadratic responses (P < 0.05), and the minimum rumination time per bolus was 44.37 s with 35.19% PKM. A quadratic response was also observed for total chewing time and both measures of merycism mastications (P < 0.05). Therefore, we concluded that the inclusion of PKM in the diets of sheep improves some parameters of feeding behavior, and the use of PKM is recommended at DM percentages of up to 40%.

Os animais receberam dieta com silagem de milho (SM) e níveis crescentes de inclusão (0%, 15%, 30%, 45 e 60%) de farelo de dendê (FD).

“…The pelletized citrus pulp is a byproduct, of citrus juice production and has been gaining more space in the national livestock market, mainly due to its price and nutritional qualities (MENDES NETO et al, 2007). Citrus pulp is from mainly orange juice extraction, but can be made up from by-products of other citrus fruits such as lemon, tangerine and pineapple (FRAPE, 2008).…”
