“…The time spent idle and rumination efficiency of DM increased linearly (P < 0.05), while total chewing time and feeding efficiency of NDF decreased linearly with the increase of the NFC:NDF ratio (P < 0.05, Table 4). In diets based on cactus cladodes, due to their processing in forage machinery, the mucilage is exposed which favors the adherence of particles of dietary ingredients, thus, promoting less time spent on feeding when compared to diets based on other fibrous roughage sources (Rezende et al, 2020;Siqueira et al, 2018). Despite this fact, it was observed in this study that there was no difference in the time spent on feeding, which may possibly be related to the particle size when the elephant grass was chopped, favoring better incorporation of the other ingredients, as well as the age of the grass.…”

This study aimed to evaluate the effect of different non-fibrous carbohydrate (NFC):neutral detergent fiber (NDF) ratios (0.70:1, 0.90:1, 1.14:1, 1.42:1, and 1.85:1) in diets containing cactus cladodes on intake, digestibility, ruminal parameters, ingestive behavior, and microbial protein of growing heifers. Five rumen-cannulated heifers (194 ± 70 kg of body weight) were distributed in a Latin square design (5 x 5). There was a quadratic effect on the intake of dry matter (DM) (Kg day-1 and %BW) and crude protein (CP) with the increase in non-fibrous carbohydrate (NFC): neutral detergent fiber (NDF) ratio, with maximum values of 7.07 kg day-1, 2.86%, and 0.949 kg day-1, estimated for 1.37:1, 1.39:1, and 1.27:1 ratios. When the intake of NDF decreased, in turn, the intakes of NFC and TDN increased. The NDF digestibility decreased with increasing NFC levels in diets. The other nutrients were not influenced. The ruminal pH showed the lowest values at 4 hours after feeding, mainly for animals fed the 1.85:1 ratio. There was a quadratic effect for rumination time with maximum values estimated for an NFC:NDF ratio of 0.88:1. The time spent idle increased linearly, while total chewing time and feeding efficiency of NDF decreased. The urinary volume increased linearly. However, microbial protein synthesis and the efficiency of the synthesis were not influenced. The number of protozoa increased by 64.5% with the elevation of the NFC:NDF ratio. We recommend a NFC:NDF ratio of 1.37:1 in diets containing cactus cladodes, to improve the use of nutrients, without negatively affecting ruminal parameters.

“…These differences aligned with the environmental conditions under which these species exist and offer a rare insight into Opuntia traits that extend beyond applied animal feed science studies (e.g. Rezende et al ., 2020). However, these differences and the variation encompassing them are not likely to impose biologically meaningful constraints on either of the moth species focused on in this study.…”

1. Relationships between prickly pear cactus (Cactaceae: Opuntia) and specialist moth larvae (Lepidoptera: Pyralidae) are exemplar of exclusive interactions between herbivorous insects and host plants. 2. We measured nutritional and defensive factors indicative of Opuntia quality to native and invasive host-specialised moth larvae. Our goals were to investigate whether host qualities varied among and within Opuntia species, use that information to test whether host quality axes predicted occupancy by larvae in two focal O. engelmannii populations, and draw conclusions about whether these herbivores were resource limited. 3. There were minimal differences in protein, carbohydrate, fatty acid, fibre, water, and cuticular thickness, among four Opuntia species distributed throughout Texas. Macronutrient content did not differ between most species. Mucilage exudation was an induced response to herbivory. Field experiments compared pairs of O. engelmannii in which one individual hosted native Melitara doddalis or invasive Cactoblastis cactorum larvae, and the other did not; host quality and nutritional space did not predict herbivore occupancy. Moreover, ordination of host quality traits did not reveal spatial aggregation of cacti with and without herbivores. 4. These results demonstrated that neither moth species was resource limited. An overall lack of variation among and within Texas Opuntia indicate that these species were suitable resources to invasive C. cactorum that recently established in Texas. 5. Outcomes of this study have serious implications for Opuntia, native moths, and associated food webs, that will soon interact with an expanding C. cactorum population as it spreads inland from the Texas Gulf Coast.

“…De acordo com Oliveira et al (2007), na dieta de vacas holandesas em lactação, substitui o milho e parte do feno do capim-tifton sem alterar a produção e a composição do leite. Em um estudo realizado com ovinos, Rezende et al (2020), observaram que a substituição de 80% da silagem de sorgo (com 35% de concentrado) aumentou substancialmente a ingestão de nutrientes, principalmente energia. De acordo com Monteiro et al (2018), a utilização da palma forrageira em uma dieta com taxa de volumoso concentrado de 70:30 atendeu os requerimentos nutricionais de vacas em lactação com rendimento médio de dessa cultura.…”

Pesquisas com palma forrageira em regiões Semiáridas são movidas pela importância de sua produção de frutos e caules suculentos (cladódios), que garantem fonte de água e nutrientes em quantidade e qualidade para as pessoas e animais destes locais. Recentemente, a busca por substâncias naturais, incluindo os metabólitos secundários de plantas (MSPs), evidenciou uma quantidade expressiva desses compostos na palma forrageira, com efeitos na alimentação e saúde. Esta revisão foi baseada em resultados de pesquisas científicas realizadas por especialistas da área com o objetivo de investigar a presença dos dos MSPs e seus benefícios na saúde e na alimentação das pessoas e animais ruminantes. Foi observado efeito positivo MSPs, como antioxidantes, agindo na prevenç ão de doenças, minimizando doenças crônicas em humanos e melhorando a produção animal, ao proporcionar aumento da ingestão de nutrientes, melhoria na fermentação ruminal, diminuição do estresse oxidativo e da excreção de metano. Portanto, a habitual utilização de palma forrageira na alimentação de ruminantes no Semiárido brasileiro e sua riqueza em MSPs requerem pesquisas que assegurem a ação destes quando presentes na dieta de ruminantes. Assim, a palma forrageira merece destaque pelos seus múltiplos benefícios em relação à saúde e alimentação, além de agregar valor aos produtos de origem animal e vegetal, contribuindo com a sustentabilidade das regiões áridas.
