“…These results are consistent with those reported by Costa et al (2011), for the total chewing time, number of cuds and number of chews per day (SILVA et al, 2005), and total chewing time, as well as Pereira et al (2007) and Mendonça et al (2004), for the number of chews per cud and rumination efficiency, which also found no significant effect of treatment on these variables. Pereira et al (2007) tested diets with different levels of fiber for confined dairy heifers and verified that the increase in NDF content in the diet increases total chewing time, number of chews per cud and per day and number of cuds.…”

This study evaluated the feeding behavior of lactating cows on pasture of Brachiaria (Urochloa) decumbens fed with concentrate supplementation containing different levels of castor meal inclusion treated with calcium hydroxide Ca (OH) 2, in the proportions of 0; 3.3; 6.6 to 10% of the total diet. Eight cows (degree of blood ½ to ¾ Holstein x Zebu), with previous average production of 3000-4000 kg adjusted to 300 days of lactation and average body weight of 465.16 kg ± 65.45 kg were distributed in two 4 x 4 Latin squares. The behavior was assessed every five minutes for 24 hours on the 21 st day of each period. The results were tested by analysis of variance and regression at p < 0.05 probability. The time spent in grazing, rumination, idle and in the trough; total chewing time, number of cuds per day, chewing per day; chewing per cud; the number of periods of grazing, rumination, idle and in the trough; time spent by period of grazing, rumination, idle and in the trough were not different between treatments. The feed efficiency (g DM h -1 ; g NDFa h -1 and g TDN h -1 ) and time spent per cud ruminated TSR sec cud -1 ) were linearly reduced. It is recommended to include up to 10% castor meal treated with Ca (OH) 2 in the total diet. Key words: Bite. Co-product. Pasture. Ruminant.

Utilizaram-se oito vacas (grau de sangue ½ a ¾ Holandês x Zebu), com produção média anterior entre 3.000 a 4.000 kg, ajustada para 300 dias de lactação e peso corporal médio 465,16 kg ± 65,45 kg. cinco minutos, durante 24 horas no 21º dia de cada período. Os resultados foram submetidos a análises de variância e regressão a 0,05 de probabilidade.

A eficiência de alimentação (em g MS h -1 ; g FDNc h -1 e g NDT h -1 ) e tempo gasto por bolo ruminado TRB seg bolo -1 reduziram linearmente.

Resumo -O objetivo deste trabalho foi estudar os efeitos de diferentes níveis de farelo de cacau e torta de dendê (0, 15 e 30%) em substituição ao milho e farelo de soja no concentrado, sobre o comportamento ingestivo de cinco cabras Saanen, lactantes, não prenhes, com peso corporal médio inicial de 41,6 kg, alojadas em baias individuais durante cinco períodos experimentais. O volumoso utilizado foi a silagem de milho, em proporção de 40:60 (volumoso:concentrado). Distribuídos em um delineamento em quadrado latino 5x5, os animais foram observados em cada um dos cinco tratamentos, ao final de cada período experimental, durante 24 horas, a intervalos de 10 minutos. Não houve diferença entre os tempos de alimentação, ruminação e ócio. Embora os animais que receberam 30% de farelo de cacau tenham reduzido o consumo de matéria seca (MS), a eficiência alimentar (em g de MS/h e g de FDN/h) foi semelhante em todos os tratamentos. No entanto, a eficiência de ruminação (em g de MS/h e g de FDN/h) e a quantidade de MS e FDN (g/bolo ruminado) foram maiores nos animais com dietas de 30% de farelo de cacau. O tempo total de mastigações (h/dia), o número de bolos ruminados (n o /dia), o número de mastigações merícicas (n o /dia e n o /bolo) e o tempo de mastigações merícicas por bolo (s/bolo) não apresentaram diferenças significativas. A inclusão de farelo de cacau ou torta de dendê na dieta influenciou parâmetros do comportamento ingestivo.Termos para indexação: alimentação, descanso, ruminação, subprodutos. Ingestive behavior of dairy goats fed on cocoa meal or palm cakeAbstract -The objective of this work was to study the effects of different cocoa meal and palm cake levels (0, 15 and 30%) in substitution to corn and soybean meal, on the ingestive behavior of five non-pregnant lactating Saanen goats, with initial body weight of 41.6 kg. Animals were housed in individual barns during five experimental periods and were distribuided in a 5x5 latin square desing. Each animal was observed in each treatment, at the end of the experimental period, during 24 hours, with 10 minutes intervals. The roughage used was corn silage in 40:60 roughage:concentrate proportion. There was no difference in the feeding, ruminating and idle times. Although animals receiving 30% cocoa meal showed a reduction in dry matter intake, the feeding efficiency, in g of DM/h and g of NDF/h, was similar in all treatments. Rumination efficiency, in g of DM/h and g of NDF/h, and DM and grams of DM of NDF/ruminated boli were decreased by 30% cocoa meal. The total chewing time (h/day), the number of ruminated (boli/day), the ruminating chews (no/day and no/boli) and the time of ruminating chews boli (sec/boli) did not show any significant difference. The cocoa meal or palm cake inclusion in the diet influenced some ingestive behavior parameters.

“…Studying the ingestive behavior is an important tool for evaluating the animal response to certain diets, because it allows for understanding the factors acting on the regulation of the intake of feed and water, thus making it possible to establish adjustments in the feeding management of animals aiming at better productive performance (CARVALHO et al, 2004;MENDONÇA et al, 2004). Therefore, strategies in the elaboration of diets, to meet the different production systems, in the arid and semi-arid environments, are of utmost importance, since these regions present low forage availability and one of the most scarce essential elements for life is water.…”

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.
