“…It is likely that the higher neutral detergent fibre content of diets containing higher levels of lucerne meal contributes to an increase in the bulkiness of the diet, which places a physical limitation on appetite as gut capacity is reached 40. In addition, the presence of compounds such as saponins has been suggested to reduce the palatability of lucerne 10–12…”

“…The principal problem with lucerne is the fact that it has a low energy level due to its high crude fibre content 5. In addition, the protein in lucerne is poorly digested,6–9 while toxins such as saponins reduce the palatability of lucerne, resulting in a reduced growth rate for pigs fed diets containing high levels of dehydrated lucerne 10–12…”

BACKGROUND: Plant breeders have attempted to improve the nutritonal value of lucerne (alfalfa) by selecting for higher protein and lower fibre concentrations. Although targeted at ruminants, such changes could also improve the nutritional value of lucerne for monogastrics. The objective of this study was to determine the effects of graded levels of dehydrated lucerne meal on nutrient digestibility, performance and carcass traits of swine.

“…But an addition of more than 5% alfalfa meal in a diet had a negative effect on average daily gain in the present study. The growth rate decreased by increasing the amounts of alfalfa meal in a diet, partly due to the low palatability of alfalfa (Leamaster and Cheeke 1979) and the subsequent reduction in feed intake (Thacker and Haq 2008).…”

Effect of Graded Levels of Fiber from Alfalfa Meal on Nutrient Digestibility and Flow of Fattening Pigs

The fiber level and composition have an important effect on nutrient digestibility of swine diets. Little information is known about the effects of fiber level and composition from alfalfa meal on nutrient digestibility of fattening pigs fed a corn-soybean meal-based diet. The objective of this experiment was to determine the effects of alfalfa fiber on the growth performance, intestinal nutrient flow, and apparent total tract digestibility (ATTD) of nutrients in fattening pigs. Twenty-four barrows (Duroc×(Large White×Landrace), body weight=(60.6±0.7) kg) were randomly allotted to 4 treatments with 6 replicates of 1 pig per replicate. The pigs were provided a control diet or a diet contained 5, 10 or 20% of alfalfa meal during a 14-d experiment period. Average daily gain (ADG) and the ATTD of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and gross energy (GE) reduced linearly as the level of alfalfa meal in the diet increased (P<0.01). The total tract flow of DM, OM, CP, NDF, ADF, and GE increased with the increase in dietary alfalfa (linear, P<0.05). Growth performance and nutrient digestion were not affected by inclusion of 5% alfalfa meal in the diet (P>0.05). A multiple linear regression analysis, taking into account both soluble and insoluble fiber intake, explained approximately 70% of the variation in the ATTD of DM, OM, NDF, and GE (P<0.01). In conclusion, alfalfa meal should be limited to less than 5% of the diet in fattening pigs to maximize growth performance and nutrient digestion. Soluble and insoluble fiber from alfalfa meal has the differential roles in nutrient digestion, which may help explain the main variation observed in nutrient digestibility. These findings suggest that knowledge of specific fiber components is necessary to accurately predict the effects of dietary fiber on nutrient digestibility.

“…For example, Leamaster and Cheeke (1979) showed that at all dietary levels of alfalfa exceeding 0.5% of the diet, pigs preferred an alfalfa-free control diet. Various avian species (goose, turkey, quail, chicken) likewise showed an aversion to low dietary levels of alfalfa meal .…”

Saponins occur in numerous forages and crop plants used to provide feed for domestic animals. The objective of this paper is to review the significance of saponins to animal production, with particular emphasis on new findings. In some cases, saponins are being revisited after a period of many years of inactivity. This applies, for example, to the roles of saponins in bloat and photosensitization.Forage saponins of concern have traditionally been those of alfalfa and to a lesser extent clovers. Recently, saponins in tropical grasses have been found to have important implications in performance of grazing animals and a dermatitic condition called secondary photosensitization. Pasture and range weeds containing saponins have been implicated in photosensitization and reproductive disorders. Crop plants containing saponins include soybeans and minor grains such as quinoa and amaranth. The saponin-rich extracts of Yucca schidigera have been of extensive interest in animal and poultry production, because of their ammonia-binding properties.The physiological effects of saponins have been reviewed previously
