“…These observed results are in line with previous findings in which the so-called “ Cactus Effect ” or “ Opuntia Effect ” exerted a positive action upon the reproductive outcomes without increases in live weight in sheep [27,28,29]. In fact, precedent reports have defined a positive effect of cladodes supplementation upon both growth and developmental competence of preovulatory follicles as well as the ovulation rate in sheep [5,27,28,29]. However, when compared with the supplementation of Opuntia cladodes + soybean, commercial concentrate and soybean meal, the cactus cladodes-group depicted non-different reproductive outcomes in fat-tailed Barbarine ewes [5].…”

“…Moreover, such a physiological scenario was observed in goats managed under grazing conditions during the dry season, facing an increased photoperiod (April to June; 25° N) and facing quite high environmental temperatures (>42°). These observed results are in line with previous findings in which the so-called “ Cactus Effect ” or “ Opuntia Effect ” exerted a positive action upon the reproductive outcomes without increases in live weight in sheep [27,28,29].

The effect of protein enriched Opuntia cladodes supplementation upon changes of serum total protein, urea, cholesterol, glucose as related to estrus induction (EI%), estrus latency (EL, h), and ovulation rate (OR, units) in adult anestrous goats exposed to the male effect was evaluated. In late April, anestrus goats (n = 45, 25° N) homogeneous regarding live weight (LE; 43.8 ± 1.6 kg) and body condition score (BCS; 2.3 ± 0.1 units) were randomly assigned to: (1). Protein-enriched Opuntia (PEO; n = 15; 29.8% CP, 2.2 Mcal ME kg−1), (2). Non-enriched Opuntia (NEO; n = 15; 6.4% CP, 2.1 Mcal ME kg−1), and (3). Control (CON; n = 15). NEO and PEO goats were individually supplemented with cladodes (160 g d−1; 0900–1000 h), thereafter all groups grazed in a marginal rangeland (1000–1800 h). Neither LW (p > 0.05) nor BCS (p > 0.05) differed among groups, yet an increased (p < 0.05) EI % (100, 57, 42 ± 0.16%), EL h (62, 60, 32 ± 4.2 h), and OR (1.33, 0.71, 0.43 ± 0.23 units) occurred in PEO and NEO vs. CONT, respectively. However, neither blood metabolites differed among groups nor a treatment x time interaction occurred. Peri-breeding protein enriched Opuntia cladodes supplementation of anestrous goats exposed to active males increased (p < 0.01) reproductive outcomes during the non-breeding season.

Several studies have shown the remarkable properties of Opuntia spp., a largely distributedspecies in the world. It has been used as an edible resource, especially in periods of foodshortage, and also as livestock food in arid lands. This review aimed at identifying currentliterature related to Opuntia spp. as forage and its validation through experiences withdomestic and other animals. The literature review was carried out October 3, 2014 using theScopus database. From 5,723 documents, 98 of them were selected, all of those whichinvolved experiences with animals both in housing conditions and in extensive grazing. Thefollowing items were analyzed: publication year, document type, source title, author affiliationand country, source type, language, animal species used in the experiences and a particularanalysis of the publications in the Journal of the Professional Association for CactusDevelopment according to Scopus. It was detected that Scopus omitted some documents inthe review, and there were few contributions regarding experiences that include cactus aspart of animal diets.
