“…In Figure 1 we can observe that during the daily period, for all experimental treatments, the animals showed higher feeding peaks, with 25 and 30% for the periods of 06:00 to 11:00 h and 12:00 to 17:00 h, respectively, during 24 hours, which corresponded to the times of feed supply, which were precisely at 09:00 and 15:00 h. This is in agreement with the reports of Abijaoude et al (2000), who claimed that, in general, ruminants (goat, sheep and cattle) present two long feeding periods during the day, especially when kept confined. These results also corroborate Mendes Neto et al (2007), who also supplied a diet twice daily and observed that the ingestion period (75.68%) was longer during the day.…”

The objective of the present study was to evaluate the effect of four water salinity levels on the ingestive behavior of non-castrated crossbred Santa Inês sheep. Thirty-two non-castrated crossbred Santa Inês sheep in feedlot, at seven months of age and initial average weight of 21.76±1.25 kg, were used in the experiment. The experimental design was completely randomized, with four treatments and eight replicates. Four concentrations of salts in the water fed to the animals were evaluated: low (640 mg/l); medium (3,188 mg/l); high (5,740 mg/l) and very high (8,326 mg/l) levels of total dissolved solids (TDS). For the ingestive behaviors, the animals were observed every ten minutes, for 24 hours, to determine the time spent feeding, ruminating and idle. Also, cud chewing and the average number of defecations and urinations and the frequency of water ingestion were determined. The time spent feeding, ruminating and idle were not changed by the salinity levels in the water. Dry matter intake, neutral detergent fiber intake, total chewing time, total cud chews per day, number of daily meals, average duration of each meal and number of defecations per day did not change either. However, feeding and rumination efficiency in grams of DM/h, water intake and number of urinations were linearly affected, whereas the variables rumination efficiency in grams of NDF/h, grams of dry matter per cud, grams of neutral detergent fiber per cud, number of cuds, number of chews per cud and chewing time per cud presented quadratic effect. The different levels of total dissolved solids (640; 3,188; 5,740; and 8.326 mg/l) in the water fed to the sheep did not cause alterations in their ingestive behavior. In conclusion, water with up to 8,326 mg TDS/l can be an alternative strategic and seasonal method to water crossbred Santa Ines sheep.

“…Likewise, several authors found no differences for number of chewing per bolus ruminated in lactating cows and heifers finished in feedlot and fed with different diets. The observed values were close to 52 chewing per bolus and 46 seconds per each ruminated bolus (MENDONçA et al, 2004;MENDES NETO et al, 2007). Those published data show that such parameters exhibit great variation depending on the various factors that can influence these variables.…”

Glycerin and cashew and castor oils in the diets for bulls in finished in feed lot: ingestive behavior

et al. 2014

This study was carried out to evaluate partial replacing of corn (15% of total diet DM) and cashew and castor oils addition on ingestive behavior of Nellore bulls in feedlot. Thirty bulls of 24 ± 2 months old and 400 ± 34 kg body weight were used. The bulls were distributed in a completely randomized design (10 bulls per treatment) and housed in collective pens. The experimental diets were: Control -CON; Glycerine -GLY and Glycerine + Functional oils. The observation scales did not influence time spent eating, ruminating or resting, as well as, the total number of chewing; however the number of periods and the time period for such activities differed among the scales time. There was no difference for the number of observations turns and number of observations per turn for analyzed variables. Glycerine inclusion in the diets caused a decrease on ruminating time and an increase in resting time. The numbers for both eating and resting periods, and time per resting period differed among diets, however, the number for ruminating period, eating time and rumination period were similar among diets. Both glycerine and functional oils inclusion in the diets increased the number of ruminated bolus per day, number of chewed per day and total chewing time for cattle.

Trinta bovinos de 24 ± 2 meses de idade e 400 ± 34 kg de peso corporal foram usados. Os animais foram distribuídos em um modelo estatístico inteiramente casualizado (10 animais por tratamento) e estabulados em baias coletivas. As dietas experimentais foram: Controle -CON; Glicerina -GLI e GOF -Glicerina + óleos funcionais. As escalas de observações não influenciaram o tempo de ingestão, ruminação e ócio, assim como o número total de mastigação; entretanto, o número de período e o tempo de período de cada atividade diferiram entre os tempos de escalas. Não houve diferença para os turnos

“…However, it was higher than that observed by Marques et al (2003) who assessed ingestive behavior of steers for 24 hours in Panicum maximum cv IPR86 Millennium in the northwestern Paraná during the summer and found approximately 66.75% of grazing time from 6 a.m. to 6 p.m., with 310.52 minutes grazing time. Mendes Neto et al (2007) also found that the food intake was higher during the day (75.68% of feeding activity occurred between 6 a.m. and 6 p.m.).…”

-It was aimed to verify the effect of the presence of trees and their heights in silvipastoral system on the intake behavior of Nellore heifers in the summer. Ten heifers for the following systems were used: system without shade, silvipastoral system with 8-meter and 18-meter trees. The data were collected in three days during 12 hours, subdivided in morning (7:15 a.m. to 1. p.m.) and afternoon (1:15 p.m. to 7 p.m.). It was evaluated the times and frequency of grazing, rumination, idle and the percentage of time that the animals remained in the shade; black globe-humidity index, whose average and minimum values (86 and 82) were equal for 8-meter tree system and 18-meter tree system; however they were lower when compared to the without shade system (89 and 86). There was an interaction between the systems and the periods for all the analyzed variables, except for the rumination frequency. For system without shade, the grazing time did not differ between morning (202 min) and afternoon (187 min); however the grazing frequency was lower for the afternoon (3.17). For 8-meter trees systems and 18 meter trees system, the grazing time in the afternoon, respectively, with 195.50 and 219.00 min was higher than in the morning, respectively, with 128.00 and 158.50 minutes. The rumination time was higher in the morning for all systems. The grazing frequency for 8-meter trees was 3.58, for the without shade system it was 3.05 and for 18-meter tree system it was 2.22. A higher idle time and the idle frequency was found in system without shade (97.50 min and 3.80 respectively) in the afternoon. For 8-meter tree system (98.50 min and 4.47 respectively) and 18-meter tree system (127.00 min and 4.27 respectively), they were higher in the morning.
