“…For example, interaction between tannins and lectins removed the inhibitory action of tannins on amylase (Fish and Thompson, 1991), while interactions between tannins and cyanogenic glycosides (Goldstein and Spencer, 1985) or tannin and saponin (Freeland et al, 1985) reduced the deleterious effects of the latter.…”

“…Simultaneous consumption of saponin and tannin resulted in the loss of their individual toxicity to rats (Freeland et al, 1985). This is considered to be due to chemical reactions between them, leading to the formation of tannin-saponin complexes, inactivating the biological activity of both.…”

“…This finding suggests that deactivation of the saponins may have occurred before reaching the rumen, probably in the mouth by saliva. Saponins bind with tannins in the gut (Freeland et al 1985). The nullification of the toxic effects of tannins was dependent on the relative proportions of tannin and saponin (Freeland et al 1985).…”

Inadequate nutrition is the main cause of low productivity by ruminants in sub-Saharan Africa. The primary feed resources in the region include natural pasture and crop residues that have tough texture, poor digestibility and are deficient in nutrients. These deficiencies can be corrected by supplementation with high-density feeds such as oilseed cakes and proteins of animal origin. However, protein sources such as oilseed cakes are beyond the economic reach of most farmers, while the incidence of bovine spongiform encephalopathy in Western intensive animal production may be thought to argue against the use of animal proteins. Local tree legumes have been investigated as potential supplements for ruminants because of their beneficial effect of increasing metabolizable energy intake, N intake and feed efficiency, and improving animal performance. However, our work has suggested that some plant materials may have a nutritional value beyond simply their nutrient content, i.e. as rumen-manipulating agents. The foliage of some tree legumes has been shown to be selectively toxic to rumen protozoa. Rumen protozoa ingest and digest bacteria and fungi, degrading their cellular protein to NH3. Microbial protein turnover due to protozoal predation in the rumen may result in the net microbial protein outflow being less than half the total protein synthesized. Results fromin vivoexperiments have clearly shown that duodenal flow of both undegraded dietary and bacterial protein is generally increased by defaunation. However, no practical method has been developed to date to eliminate protozoa. Anti-protozoal plants may be promising, safe, natural defaunating agents.

“…Eating a combination of plants with complementary SC can thus be beneficial compared with eating any one SC in isolation . Rats eat more of a combination of foods containing tannins and saponins, evidently because tannins and saponins chelate in the intestinal tract, reducing the negative effects of both components (Freeland et al, 1985), although such complementarities were not observed with sheep (Burritt and Provenza, 2000). When lambs can choose between foods that contain either amygdalin or lithium chloride, they eat more than lambs offered a food that contains only one of these compounds; the same is true with nitrate and oxalate (Burritt and Provenza, 2000).…”

We determined whether plant diversity and sequence of plant ingestion affected foraging when cattle chose from plants that varied in concentrations of alkaloids, tannins and saponins. We hypothesized cattle that ate high-alkaloid grasses (endophyteinfected tall fescue (TF) or reed canarygrass (RCG)) would prefer forages high in tannins (birdsfoot trefoil, BFT1) or saponins (alfalfa, ALF1), because tannins and saponins can bind to alkaloids, presumably reducing their absorption. We further hypothesized that forages with tannins or saponins consumed before, rather than after, foraging on high-alkaloid grasses would promote greater use of those grasses presumably by binding to alkaloids, thereby reducing their absorption. In Phase 1, cattle (n 5 32) grazed on either high (1) or low (2) alkaloid grass (TF or RCG) pastures for 30 min each morning at 0600 h and were then offered a choice of BFT1, BFT2, ALF1 and ALF2 for 60 min each day for 12 days. In Phase 2, cattle (n 5 32) were first offered a choice of BFT1 or ALF1 for 30 min at 0600 h and then placed on grass (TF1 or 2, or RCG1 or 2) pastures for 60 min for 12 days. In both phases, we had four spatial replications of four treatments with 2 per calves assigned to each of the 16 replications per treatment combinations. Scan samples of individuals at 2-min intervals were used to determine incidence of foraging on each plant species (%). Cattle grazed more on RCG than on TF in Phases 1 (62% v. 27%; P 5 0.0015) and 2 (71% v. 32%; P 5 0.0005). In Phase 1, cattle that first foraged on RCG1 or TF2 subsequently preferred ALF over BFT, whereas cattle offered RCG2 or TF1 foraged on ALF and BFT equally. Foraging by cattle on RCG was cyclic during Phase 1, whereas cattle foraging on TF markedly decreased incidence of use of TF from 41% to only 16% by the end of the 12-day trial (P 5 0.0029). Contrary to the cyclic (RCG) or steadily declining (TF) use of grasses in Phase 1, cattle steadily and dramatically increased foraging on both RCG and TF throughout Phase 2, when they first grazed BFT1 or ALF1 followed by high-alkaloid grasses (P 5 0.0159). Our findings suggest that in plant species the sequence of ingestion influenced foraging behavior of cattle and that secondary compounds influenced those responses.
