“…The NDF and ADF values obtained in this study for prickly pear cactus cultivars were similar to those reported by other authors (Gebremariam et al 2006;Batista et al 2009;Costa et al 2009;Barbosa et al 2012). The hemicellulose content calculated in this study varied in ranges from 96 to 249 g kg -1 DM, similar values to those reported in studies of Batista et al (2003) and Abidi et al (2009) where the estimated difference between NDF and ADF values were in average 102 and 123 respectively.…”

In production systems of prickly pear fruit and prickly pear cactus, significant amounts of pruned material, which could be used as an ingredient in animal feeding, is generated. The aim of this study was to measure the nutrient content, fermentation kinetics and in vitro digestibility of eleven cultivars of cladodes of prickly pear cactus. The fermentation was measured indirectly using the gas production technique, where 500 mg of DM substrate (prickly pear cactus cultivars) were placed in amber glass flasks of 125 mL with 90 mL of ruminal inoculum under a continuous flow of CO 2 . Flasks were hermetically wrapped up with a rubber stopper and a metal ring, and were placed in a water bath at 39°C. The fermentation gas pressure was measured using a monometer at 0, 2, 4, 6, 8, 12, 16, 20, 24, 32, 38, 50 and 72 h incubation. Results show that the chemical composition ranged between (g kg -1 DM): 64 and 160 g kg -1 dry matter (DM), 137-293 g kg -1 DM ash, 52-101 g kg -1 DM crude protein, 3-22 g kg -1 DM ether extract, 251-393 neutral detergent fiber and 132-192 acid detergent fiber. The gas volume was different (p \ 0.05) among cultivars, with the Red Vigor cultivar having the largest volume at 378 mL g -1 DM. The highest volume of gas was produced during the first 24 h in on average 67 % of the total produced. The in vitro DM digestibility displayed values of up to 82 % in the Roja Pelota cultivar. It can be concluded that the cladodes of prickly pear cactus from different cultivars can be used in animal feed for its good rumen fermentation characteristics.

“…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.…”

“…Thus, the animals fed this silage (21 and 42%) ingested much more water (2.5 and 3.81 kg) than those fed control diet (1.4 kg), leading to a higher urinary frequency. Barbosa et al (2012) worked with forage cactus and urea in the diet of goats and observed a higher number of urination in animals fed higher levels of forage cactus in the 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 ...

“…The degradation of crude protein can be influenced by the ratio of non-protein nitrogen (NPN-urea) to true protein (wheat bran). Non-protein nitrogen is easily degraded and absorbed, while true protein has peptide bonds that hinder microbial access to protein molecules, making them more resistant to microbial degradation (Barbosa et al, 2012). Particularly, the observed increase in rumen digestibility of CP was due to the replacement of the true protein from wheat bran by urea (NPN).…”

-The effect of replacing wheat bran with spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on the intake of nutrients, feeding behavior, and rumen digestibility of steers was assessed using digested samples collected from the omasum. Five crossbred steers (½ Holstein-Zebu) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. Samples of omasal digesta were collected for three days. Rumen was evacuated via the rumen cannula to determine the rumen pool of dry matter (DM), neutral detergent fiber (NDF), indigestible NDF (iNDF), intake (ki), passage (kp) and degradation (NDF) rates, and the passage of iNDF (kpi). Nutrient intake displayed a quadratic effect, with maximum intakes of DM (5.73 kg d −1 ), non-fiber carbohydrates (NFC, 4.63 kg d −1 ), and digestible organic matter (DOM, 3.45 kg d −1 ) estimated at the replacement levels of 54.63, 60.00, and 43.17%, respectively. The replacement levels showed no effect on feeding, rumination, or idle times. There was a linear increase in the total apparent and ruminal digestibility of CP as the spineless cactus content in the diet was increased. There was no effect on total and partial digestibilities of OM and NDF or on intestinal digestibility of CP. No effect was observed on the rumen pool of DM, NDF, or iNDF. Furthermore, ki, kp, NDF degradation, and iNDF passage rates displayed a quadratic effect, with higher concentrations estimated for replacement levels of 56.07, 56.12, 59.00, and 55.20%, respectively. Replacing 55% wheat bran with spineless cactus in sugar cane-based diets is recommended.
