“…All species in this study contained low levels of rapidly degradable TP fraction (B1) (average of 8 % of the TP). The CP and TP fraction values for alfalfa are in good agreement with those reported in the literature, and indicate that intermediately degradable protein is the main protein fraction in this species (Lintzenich et al. 1995, NRC 1996, 2001, Mustafa et al.…”

Kura clover (Trifolium ambiguum M.B.) is a persistent rhizomatous forage legume with great potential for permanent pastures. The effects of a soil moisture deficit on forage quality, digestibility and protein fractionation of two cultivars of Kura clover (Endura and Rhizo) were investigated in this study for 1 year. The responses of alfalfa (Medicago sativa L.) and red clover (Trifolium pratense L.) were also characterized. Stands of each species were field-grown and submitted to two soil water regimes promoting soil moisture deficits and well-watered (i.e. control) conditions. There were no interactions between species and soil water regimes. Soil moisture deficit increased acid detergent fibre (ADF) but reduced acid detergent lignin (ADL) content and consequently increased forage digestibility. It had only minor effects on protein content and fractionation. Species varied for most parameters measured. Kura clover generally had the lowest neutral detergent fibre (NDF), ADF and ADL contents, and consequently the greatest digestibility (83.9 %). Species also differed in their crude protein fractionation. Kura clover and red clover had a lower proportion of non-protein nitrogen (NPN; A fraction) and a greater proportion of true protein (B fraction) (30.9 and 64.5 %, respectively) than alfalfa (36.4 and 57.4 %, respectively). Kura clover also had the lowest proportion (i.e. 4.7 %) of acid detergent insoluble protein (ADIP; C fraction) of all species tested. Endura Kura clover often had a higher forage quality than Rhizo. This study confirms that Kura clover produces high-quality forage and provides the first estimates of protein fractionation in this species.

“…High levels of rapidly degradable carbohydrates have also been reported for other forages. 27 Total digestible nutrients concentrations were similar for the cactus varieties and averaged 667 g kg −1 . Based on NRC 8 values, the TDN (Total digestive nutrient) values of cactus may be equivalent to that of good quality alfalfa hay.…”

“…However, values of true protein fractions reported in this study for cacti are similar to those reported for other forages, such as alfalfa products. 27 Mineral analysis showed that cactus varieties contained high calcium (Ca) and magnesium and low phosphorus (P) and copper concentrations ( Table 3). The Miúda variety contained higher (P < 0.05) Ca and lower (P < 0.05) manganese levels than the other two varieties.…”

This study determined the chemical composition, in situ ruminal nutrient disappearance and in vitro gas production kinetics of three cactus varieties grown in northeastern Brazil. The varieties were Gigante, IPA-20 and Miúda. Results of the chemical analysis showed no significant differences in ash, ether extract, crude protein (CP) and neutral detergent fibre (NDF) between the cactus varieties. However, acid detergent fibre was highest (P < 0.05) for IPA-20, intermediate (P < 0.05) for Gigante, and lowest (P < 0.05) for Miúda. Fractionation of carbohydrate and true protein based on rates of ruminal degradation indicated that the main carbohydrate component was the rapidly degradable fraction, whereas the main true protein component was the intermediately degradable fraction. No differences in carbohydrate or protein fractions were observed between the cactus varieties. Results of the in situ experiment showed no differences in ruminal dry matter (DM, average 803 g kg −1 of DM), CP (900 g kg −1 of CP) and NDF (611 g kg −1 of NDF) disappearance between the three cactus varieties after 48 h of ruminal incubation. Potential gas production at the end of 48 h of incubation was higher (P < 0.05) for Gigante than for the Miúda or IPA-20 variety. However, rate of gas production and lag time in gas production were similar for the three cactus varieties at 6.8% h −1 and 0.6 h respectively. Our results showed little or no differences in chemical composition or ruminal nutrient degradabilities between the three cactus varieties.

“…Lucerne is mainly used to make hay and silage, but can also be used for grazing purposes, because of its high yield, quality and wide adaptability to different climates and soil types (NLO, 2010). Lucerne may be grown as a cover crop and often increases yield of succeeding crops such as potatoes, rice, cucumber, lettuce and tomatoes (Mustafa et al , 2001).…”

PurposeThe aim of this review is to focus on the potential utilisation of lucerne which could contribute more effectively to human nutrition and food sustainability. It aims to explore a proposed cycle for the promotion of lucerne for human consumption. Furthermore it seeks to propose lucerne as a potential vegetable and to briefly discuss the chemical composition, protein application, safety and medicinal uses of lucerne.Design/methodology/approachA non‐experimental approach, namely a systematic literature study, was used. During the study searches were done on the scientific databases Science Direct, Sabinet online, Emerald, EbscoHost and SpringerLink. Moreover internet searches were undertaken on the search engine, Google Scholar. Additionally, available textbooks and theses were consulted. Different combinations of keywords as well as synonyms for keywords were used during the searches. Some keywords used included lucerne, alfalfa and legumes.FindingsThe high costs of animal protein have led to a growing interest in the industrial applications of lucerne in developing countries as lucerne is a valuable source of protein, suitable to produce nutritional food for human consumers. The full development of lucerne's potential is hindered by a lack of awareness among consumers as well as by a lack of capacity within a research community. Therefore the key steps in the proposed cycle can be used to aid in the diversification of lucerne in the market place.Originality/valueTo the author's knowledge there exists a lack of previous reviews on lucerne. It is important for scientists to become aware of the nutritional and entrepreneurial potential and contribution for human consumption purposes in the future in order for the lucerne industry to diversify.
