“…NDF and ADF) and in vitro digestibility of spineless cactus are functions of maturation stage and are in agreement with Repetto et al (2003). In this regard, Batista et al (2003) stated that IVDMD of spineless cactus could be similar or higher than that of conventional forages such as lucerne. Therefore, the kinetic variables of its IVDMD suggest that spineless cactus could be good forage to ruminants.…”

A randomized complete block design with five replications was used to assess biomass yield, in vitro dry matter digestibility (IVDMD) and nutritional value of spineless cactus (Opuntia ficus-indica) produced under drip irrigation and fertilization. Cladodes were harvested from an established plantation at 30, 37, 45, 60, 75 and 90 d of growth. Weight per cladode increased linearly and length increased quadratically with maturity. Biomass yield (t/ha), gross energy (GE), dry matter (DM), crude protein (CP), neutral detergent fibre and acid detergent fibre increased quadratically with maturity. Thus, the curve became asymptotic at 60 d of growth (28.9 ± 2.1 cm). As growth progressed, concentration of CP and nitrates decreased, and that of fibre increased. In vitro solubility, potential digestibility and digestibility rate of DM decreased linearly with increased maturity of the cladodes. However, there was a quadratic effect of maturity on total digestibility of DM. Thus, the curve became asymptote at 75 d. The optimal yield of nutrients, nutritional value and IVDMD of cladodes were recorded between 60 and 75 d of age when they were 29 to 31 cm in length.

“…O aumento do IEUrK já era esperado devido a grande quantidade de K existente na palma forrageira (Batista et al 2003), já que ao aumentar a ingestão de K aumenta também a secreção de aldosterona e, consequentemente, maior IEUrK. Já a relação existente entre a concentração do Na e K no palma, esta justifica o comportamento da excreção urinária, uma vez que o menor IEUrNa foi observado nos animais que receberam palma na condição in natura, devendo-se a menor concentração deste eletrólito na composição da palma, refletindo diretamente não só a concentração sanguínea, quanto a urinária.…”

“…Batista et al (2003) analisando a composição mineral da palma forrageira, encontraram valores mais elevados de K (50mg/100g de MS), Ca (18-57mg/100g de MS) e Mg (11-17mg/100g de MS), seguidos por manganês (Mn) (62-103µg/g de MS), Fe (59-66µg/g de MS), Zn (22-27µg/g de MS), e Cu (8-9µg/g de MS), a variação encontrada na composição mineral da palma é decorrente da espécie, local de cultivo e do estado fisiológico do cladódio. O teor de P presente na palma forrageira é considerado baixo (0,08-0,16) (Germano et al 1999).…”

ABSTRACT.-Neto J.P., Soares P.C., Batisa A.M.V., Andrade S.F.J., Andrade R.P.X., Lucena R. This study aimed to assess fluid balance and renal excretion of metabolites in lambs without defined breed standard, fed different forage cactus (Nopalea cochenillifera Salm Dyck), in natura and bran. 20 lambs were used, with initial body weight of 20 kg and were distributed in a completely randomized design, with five treatments and four repetitions. The experimental diets consisted of a control diet based on Bermuda grass hay, soybean meal, limestone and mineral supplement, other treatments aimed at testing different levels of cactus pear plus urea in two forms: fresh and mash and two levels of substitution (50 and 100%) of dry matter of hay. Blood and urine samples were collected for determination of different metabolites and minerals and use of equations to determine the rates of urinary excretion of these metabolites, rate of endogenous creatinine clearance and electrolyte reabsorption of free water, in addition to recording of water intake and urine volume. The voluntary water intake was influenced by the diets, and the animals subjected to diets containing soybean meal and hay palm and cactus meal were higher than other treatments. Water intake via food was also influenced by diet, being higher in animals fed palm fresh and bran over palm in nature. With respect to total water intake was greater for cows fed diets containing palm in nature compared to the other treatments. The experimental diets influenced the renal excretion of purine metabolites and minerals derived, without changing renal function. The presence of cactus pear both as bran as in nature provides increased urine volume without changing renal function, and to be considered as an excellent food strategy in semiarid.

“…The cladodes of spiny and spineless cactus pears are used as feed for livestock during the frequent periods of food shortages or droughts in many arid and semi-arid regions (De Kock & Aucamp, 1970;Felker, 1995;Pretorius et al, 1997;Ben Salem et al, 2002;Tegegne, 2002b;Batista et al, 2003). Spineless cactus pears are valued by many farmers because of their drought resistance, high biomass yield, palatability and adaptability to a range of soils and climatic regions (Ben Salem et al, 1996;Batista et al, 2003).…”

Cactus pear cladodes in ruminant diets are characterized by the production of wet faeces and assumed to be diarrhoea. Incremental levels of sun-dried and coarsely ground spineless cactus pear (Opuntia ficusindica var. Algerian) cladodes were used to substitute part of the lucerne hay in balanced sheep diets. Feed and water intake and faeces and urine excretion were determined with 24 Dorper wethers. The four diets (T0, T12, T24 and T36) comprised respectively (air dry basis) 0, 120, 240 or 360 g/kg sun-dried, coarsely ground Opuntia cladodes; 660, 535, 410 or 285 g/kg coarsely ground lucerne hay; 300 g/kg yellow maize meal; 0, 5, 10 or 15 g/kg feed grade urea; and 40 g/kg molasses meal. The wethers drank significantly more water with increasing inclusion of Opuntia in the diets, while urine excretion showed little increase. Food intake and faeces dry matter (DM) excreted remained the same for all diets, but the DM content of the faeces decreased with higher levels of Opuntia inclusion. The wetter faeces produced by the sheep lacked the customary foul smell associated with diarrhoea and this is ascribed to the water-binding capacity of the mucilage in Opuntia. Although more definitive research is needed, it is concluded that the wetter faeces produced by the sheep on diets T12, T24 and T36 were not diarrhoea induced by the sun-dried and coarsely ground Opuntia cladodes, but the result of larger quantities of water that were not reabsorbed from the lower digestive tract.
