“…This higher efficiency observed in animals fed forage cactus silage is probably due to the absence of differences in feeding time between treatments and the higher dry matter intake observed in animals fed this silage, allowing them to consume more food per unit of time. This result is in accordance with that observed by Bispo et al (2010), who observed an increase in feeding efficiency when using forage cactus replacing elephant grass hay in sheep diet.…”

This study aimed to assess the effect of using forage cactus silage in the diet of sheep under intermittent water supply on its ingestive behavior and thermoregulation. We used in the experiment thirty-six intact male sheep of undefined genotype with an initial average weight of 19.8 ± 2.1 kg and age of approximately six months. The experimental design was a randomized block design in a 3 × 3 factorial scheme composed of three levels of forage cactus silage in the diet (0, 21, and 42%), three water supply periods (0, 24, and 48 hours), and four replications. For the ingestive behavior, observations were carried out every 5 minutes for 2 periods of 24 hours. Thermoregulatory responses were taken at 7:00 and 15:00 h on days other than those intended for ingestive behavior tests. Intermittent water supply did not affect any of the studied variables (P > 0.05). The use of forage cactus silage significantly influenced the ingestive behavior of animals (P < 0.05). Sheep fed forage cactus silage in the diet presented an average feeding efficiency of 255.77 g DM h −1 and an average rumination efficiency of 102.16 g DM h , respectively. Urinary frequency increased according to the levels of forage cactus silage in the diet, with 23.60 urination per day in animals fed diets with 42% of forage cactus silage and 10.83 urination per day in animals fed control diet. However, the search for water reduced, with averages of 2.73 and 0.54 per day for animals fed 0 and 42% forage cactus silage, respectively. The use of forage cactus silage also increased thermoregulatory responses of sheep, with an average respiratory rate of 103.35 mov. min −1 and heart rate of 140.08 mov. min−1 in the warmest period of the day (in the afternoon). Thus, sheep fed forage cactus silage increases its feeding and rumination efficiencies, decreases its search for water, and increases its thermoregulatory responses. The intermittent water supply within 48 hours does not influence the ingestive behavior and thermoregulation of confined sheep. Key words: Animal welfare. Physiological parameters. Thermoregulatory responses. Rumination. ResumoObjetivou-se avaliar o efeito da utilização de silagem de palma forrageira na dieta de ovinos submetidos a oferta intermitente de água sobre o comportamento ingestivo e a termorregulação de ovinos. Foram utilizados 36 ovinos machos não castrados sem padrão racial, com peso médio inicial de 19,8 + 2,1 kg e idade aproximada de seis meses, distribuídos em delineamento de blocos ao acaso, em esquema fatorial 3 x 3, composto por três proporções de silagem de palma na dieta (0; 21 e 42 %) e três períodos de oferta de água (0; 24 e 48 horas), com quatro repetições. Para o comportamento ingestivo foram realizadas observações a cada 5 minutos durante 2 períodos de 24 horas. As respostas termorregulatórias foram tomadas nos horários das 7 e 15 horas, em dias diferentes daqueles destinados ao comportamento. Observou-se que a oferta intermitente de água não afetou nenhuma das variáveis estudadas (P > 0,05). A utilização ...

“…Due to the high amount of water in forage cactus, the animals that fed this silage had part of their water needs already met, reducing the search for water in the drinking troughs. Bispo et al (2010), Barbosa et al (2012), andCosta et al (2012) also observed similar results.…”

“…Cactus forage is an excellent source of NFC, important source of energy for ruminants (Ferreira, Silva, Bispo, & Azevedo, 2009). The results of the present behavioral research corroborate with Bispo et al (2010), who reported an increase in DM intake by sheep when associated with cactus fiber sources, especially hay.…”

“…NFC levels in diets increased as they rapidly degraded the rumen, disappearing rapidly, increasing energy supply and favoring microbial growth and, consequently, digestion (Bispo et al, 2010).…”

The objective of this study was to evaluate the use of sorghum silage, Buffel grass hay and forage palm fodder in the diet of dairy goats by means of performance tests and economic viability of different roughage sources. Eight Anglo-Nubian goats, multiparous, weighing around 40.13 ± 2.76 kg of live weight were used. The experiment lasted 84 days, consisting of four periods of 21 days, distributed in two Latin squares (4x4). The treatments represented by diets with different volumetric sources: SSCF: (sorghum silage+ forage palm+ concentrate); BHCF: (Buffel grass hay + cactus forage+ concentrate); SS: (sorghum silage+ concentrate) and BH: (Buffel grass hay + concentrate). Nutritional intake, digestibility, feed behavior, milk production and chemical composition and economic analysis were evaluated. Animals fed the BHCF diet had higher nutrient intakes and consequently were more productive in fat, protein, lactose, fat free solids and total solids. The BHCF diet led to a higher gross income in Brazilian currency. The safety margin of the SSCF diet presented the highest percentage, with 43.06%, and the BHCF diet, the lowest percentage, of 14.89. The association of forage palm with sorghum silage and Buffel grass hay can be used as a bulky source in lactating goat diets.

“…Miranda et al (1999) worked with Holstein x Zebu crossbred heifers fed diets based on sugar cane, using different levels of NPN and probiotics and found no difference in feeding time. Bispo et al (2010) worked with lactating cows in which they added palm and urea in the diets and observed no change in feeding and idle time, probably due to the fact that consumption of DM and NDF was not influenced by the inclusion of these foods and the concentration of NDF in the diets are similar. Despite the changes in feeding and idle times, the DM and NDF intakes (Table 5) were similar (P > 0.05) between the different levels of substitution of soybean brain by urea, suggesting an adaptation of the ingestive behavior of the cows.…”

This work aimed to evaluate the ingestive behavior and milk production of F1 Holstein x Zebu cows subjected to increasing levels of urea in the diets. Diets contained 0, 33, 66 and 100% replacement of soybean bran by urea, which corresponded to 0, 0.92, 1.84 and 2.77% of CP in the form of NPN, formulated to be isoproteic and for an average production of 10 liters of milk per cow day-1. We used two 4 x 4 Latin squares, with 4 animals, 4 diets and 4 experimental periods of 18 days each, with the first 15 days of diet adaptation and the last three days for evaluation of ingestive behavior and milk production. The cows were subjected to visual observation at each period, for two consecutive days. There were differences in feeding and idle times, and total chewing time, with quadratic behavior for these variables. Feeding time decreased with 1.78% NPN and idle time increased with the level of 1.96% of CP in the form of NPN. The total chewing time decreased with 1.95% of CP in the form of NPN. The intake, chewing and ruminating time and the efficiencies of feeding and rumination of the DM and of the NDF did not differ. The replacement of soybean brain by urea in the diet of crossbred cows produced changes in the feeding, idle and total chewing times, however, it did not influence milk production of the cows.Keywords: intake, non-protein nitrogen, rumination. ResumoObjetivou-se por meio deste trabalho avaliar o comportamento ingestivo e a produção de leite de vacas F1 Holandês x Zebu submetidas a níveis crescentes de ureia nas dietas. As dietas foram constituídas de 0, 33, 66 e 100% de substituição do farelo de soja pela ureia, o que correspondeu a 0, 0,92, 1,84 e 2,77% de PB na forma de NNP, formuladas para serem isoproteicas e para uma produção média de 10 litros de leite por vaca/dia -1 . Foram utilizados dois quadrados latinos 4 x 4, com 4 animais, 4 dietas e 4 períodos experimentais de 18 dias cada, sendo os primeiros 15 dias de adaptação às dietas e os três últimos dias para avaliações do comportamento ingestivo e produção de leite. As vacas foram submetidas à observação visual a cada período, durante dois dias consecutivos. Houve diferença para os tempos de alimentação, ócio e tempo total de mastigação, com comportamento quadrático para estas variáveis. O tempo de alimentação diminuiu com 1,78% NNP e o tempo em ócio aumentou com o nível de 1,96% de PB na forma de NNP. O tempo total de mastigação diminuiu com 1,95% de PB na forma de NNP. Os tempos de consumo, mastigação e ruminação e as eficiências de alimentação e ruminação da MS e da FDN, não diferiram. A substituição do farelo de soja pela ureia na dieta de vacas mestiças ocasionou mudanças nos tempos de alimentação, ócio e tempo total de mastigação, entretanto, não influenciou a produção de leite das vacas.Palavras-chave: consumo, nitrogênio não proteico, ruminação.
