“…Alterations in the feeding, rumination and idle activities can be often verified in studies where the experimental diets vary in the fiber contents, as observed in an experiment conducted by Carvalho et al (2006), who supplied increasing levels of NDF from the forage in diets for dairy goats and found increase in the feeding and rumination times and decrease in the idle time. 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.…”

“…As the NDF level in the diet was elevated, the use efficiency of these fractions (feed and rumination efficiencies) also increased, due to the greater difficulty to reduce the particle size, which in turn may cause the feed intake to reduce (CARVALHO et al, 2006).…”

“…The groundwater found in the Brazilian Northeast semi-arid region is highly variable, containing water with different mineral concentrations, which range from 0.00002 or 0.0128 mg/l of TDS to 75 dS/m or 48,000 mg/l of TDS (CPRM, 2012), and good quality regarding the electric conductivity; and saline waters, which are improper for human consumption. These unsuitable waters for consumption can be utilized to water animals in times of scarcity or even under water shortages, so it is necessary to know the maximum concentration of salts animals can tolerate in these saline waters found in artesian wells in the Brazilian Northeast.…”

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.

“…Rumination time (RT) increased linearly with the levels of mesquite pod meal addition, because of the higher levels of NDF provided by the high participation of this ingredient in the diet. Changes in the time spent feeding and ruminating have been commonly observed in studies in which experimental diets had different fibre levels (Beauchemin, 1991;Carvalho et al, 2006). But the time spent idle (IT) increased linearly as the levels of MPM in substitution of corn were increased.…”

This study aimed to evaluate intake, digestibility, ingestive behaviour, and body weight variation in lambs fed mesquite pod meal (0, 30, 60 and 90%) in substitution of ground corn grains (as-fed basis) in pelleted diets. Twelve Santa Ines×Dorper lambs with average body weight of 25.0±1.8 kg were distributed through three 4×4 Latin Squares consisting of four periods and four treatments. Diets consisted of 30% alfalfa hay and 70% concentrate. The experimental period was 60 days, divided into 15-day periods. The intakes of dry matter (DM), total carbohydrates (TC) and total digestible nutrients (TDN) were not influenced (P>0.05) by the different levels of mesquite pod meal added in substitution of corn. The digestibility coefficients of DM, organic matter (OM), ether extracts (EE), neutral detergent fibre free of ash and protein (NDFap), TC and the TDN decreased linearly (P<0.05) as the level of mesquite pod meal in the diet was increased. Feed efficiency [g DM and neutral detergent fibre (NDF)/hour] was not influenced (P>0.05) by the mesquite pod meal levels; contrastingly, this feedstuff caused a reduction of 12.13 and 1.9 g in rumination efficiency (g DM and NDF/hour, respectively) for every percentage unit added. The average weight gain showed quadratic behaviour (P<0.05) as a result of the substitution level, and maximum weight gain was estimated at 275.9 g/day at the substitution level of 47.5%.

“…Sabe-se que as EI MS e ERU MS podem ser reduzidas quando são fornecidas aos animais dietas com elevado tamanho de partícula ou alto teor de fibra, tendo em vista a maior dificuldade para reduzir o tamanho das partículas originadas destes materiais fibrosos, com consequente queda na ingestão de alimentos (Dulphy et al, 1980;Van Soest, 1994). Da mesma forma, Carvalho et al (2006) observaram que, em cabras lactantes alimentadas com dietas contendo diferentes níveis de FDN, também houve redução nas eficiências de alimentação e ruminação com o aumento do teor de FDN das dietas.…”

 RESUMOAvaliou-se o efeito de dieta com torta de girassol, oriunda da produção de biodiesel, sobre o comportamento ingestivo e a resposta fisiológica de 32 cabritos ½ sangue Boer, não castrados, com peso médio inicial de 15,3±3,2kg e idade média de 135 dias. Utilizou-se delineamento inteiramente ao acaso, com quatro tratamentos 0; 8; 16 e 24% de inclusão da torta de girassol e oito repetições. O tempo despendido com ruminação, ócio e mastigação total não foi influenciado pela dieta, e observou-se efeito linear crescente sobre o tempo de ingestão em min/período e em min/dia. A eficiência de ingestão e ruminação da matéria seca e da fibra em detergente neutro também não diferiu entre dietas. Quanto às respostas fisiológicas, as frequências respiratória e cardíaca e as temperaturas retal e superficial não sofreram influência da dieta. Concluiu-se que a torta de girassol pode ser incluída até 24% da matéria seca em dietas de cabritos ½ sangue Boer sem comprometer o comportamento ingestivo e os parâmetros fisiológicos desses animais. O fornecimento de dietas com até 24% de matéria seca de torta de girassol não interfere no estresse calórico de cabritos.Palavras-chave: caprino, ingestão, ruminação, temperatura retal, torta de oleaginosa ABSTRACT
