“…According to Piluzza et al (2013), there have been conflicting reports on the presence of CT in forage chicory; in fact, the presence of CT was not detected in other studies on chicory (Waghorn et al, 2002;Bullitta and Piluzza, 2005;Tava, 2005;Sulas et al, 2007).…”

Knowledge about the forage yield potential and bioactive compound contents of Mediterranean natural populations of chicory is still scarce, even though it could be very helpful in view of the exploitation of the feeding value of local chicory germplasm for ruminants. Dry matter yield, chemical composition, antioxidant capacity, total polyphenols, flavonoids, and condensed tannins content were determined in 7 natural populations of Mediterranean wild chicory and, as a comparison, in the chicory commercial variety Spadona. Original seed was collected in different pastureland areas of Sardinia (Italy) and plants were grown in North Sardinia. Statistically significant differences were found in the leaf dry matter yield, ranging from 1.3 to 3.8 t ha -1 , and were not found in protein and fiber contents. The local populations were comparable to the commercial variety; however, the antioxidant activities, detected by means of 2 in vitro assays, significantly differed between populations. Among bioactive compounds, total flavonoids ranged from 27 to 37 g catechin equivalent kg -1 dry weight and statistically significant differences were also found in total polyphenol content and nontannic polyphenols; condensed tannins were not detected. Considering the importance of some bioactive compounds for the enhancement of animal nutrition and welfare, the exploitation of variability in bioactive compound content and antioxidant capacity of the chicory natural populations can be important for a more complete valorization of its Mediterranean germplasm.

“…The beneficial effects of sulla on ruminant production is particularly attributable to its high protein content, high ratio of non-structural to structural carbohydrates and moderate CT concentration ranging from 0.8% to 5% of whole-plant dry matter (DM) (Ruisi et al, 2011). Moderate CT levels (<6% DM) protect dietary protein from ruminal degradation due to the ability of CT to bind protein, thereby increasing its utilisation in the intestinal tract, and are active in the control of gastrointestinal nematode parasitism (Min et al, 2003;Piluzza et al, 2014).…”

Sulla (Sulla coronarium L.) forage is valued for its positive impact on ruminant production, in part due to its moderate content of condensed tannin (CT). The duration of daily grazing is a factor affecting the feed intake and milk production of ewes. In this study, the effects of grazing sulla pasture compared with annual ryegrass, and the extension of grazing from 8 to 22 h/day, were evaluated with regard to ewe forage intake and milk production, as well as the physicochemical properties and fatty acid (FA) composition of cheese. During 42 days in the spring, 28 ewes of the Comisana breed were divided into four groups (S8, S22, R8 and R22) that grazed sulla (S) or ryegrass (R) for 8 (0800 to 1600 h) or 22 h/day, and received no feeding supplement. In six cheese-making sessions, cheeses were manufactured from the 48 h bulk milk of each group. Compared with ewes grazing ryegrass, those grazing sulla had higher dry matter (DM) intake, intake rate and milk yield, and produced milk that was lower in fat and higher in casein. Ewes grazing for 22 h spent more time eating, which reduced the intake rate, increased DM and nutrient intake and milk yield, and reduced milk fat. Due to the ability of CT to inhibit the complete ruminal biohydrogenation of polyunsaturated fatty acids (PUFA), the FA composition of sulla cheese was more beneficial for consumer health compared with ryegrass cheese, having lower levels of saturated fatty acids and higher levels of PUFA and n-3 FA. The FA profile of S8 cheese was better than that of S22 cheese, as it was higher in branched-chain FA, monounsaturated FA, PUFA, rumenic acid (c9,t11-C18:2), and had a greater health-promoting index. The effect of short grazing time on sulla was attributed to major inhibition of PUFA biohydrogenating ruminal bacteria, presumably stimulated by the higher accumulation of sulla CT in the rumen, which is related to a higher intake rate over a shorter eating time. Thus, grazing sulla improved the performance of ewes, thereby increasing, especially with short grazing time, the nutritional properties of cheese fat.

“…Tannin has the ability to form complexes with macromolecules such as protein and carbohydrate particularly via its multiple hydroxyl groups, making the nutrients less available for rumen microbial degradation (Piluzza et al, 2014) and hence less degradability.…”

This study aimed to observe the effects of rice straw ammoniation and supplementation of Paraserianthes falcataria and Sapindus rarak on rumen fermentation and methane production in vitro. Rice straw was ammoniated by adding 2% urea. Rice straw, ammoniated rice straw, P. falcataria leaves and S. rarak fruits were oven-dried and finely ground. Experimental treatments were arranged as follow: rice straw (T1), ammoniated rice straw (T2), T2 80% + P. falcataria 20% (T3), T2 60% + P. falcataria 40% (T4), T2 80% + P. falcataria 10% + S. rarak 10% (T5), and T2 60% + P. falcataria 20% + S. rarak 20% (T6). An amount of 1 g sample from each treatment was added with 100 ml rumen fluid and buffer mixture (1:2 v/v), and incubated in a water bath at 39 ºC for 48 h. The incubation was performed in four replicates and each replicate was represented by four incubation bottles. Results showed that urea treatment increased gas production of rice straw at 24 and 48 h, higher ammonia production, higher IVDMD, and lower methane production as compared to the untreated rice straw (P<0.05). Addition of P. falcataria or S. rarak at lower level produced similar ammonia concentration as ammoniated rice straw whereas their addition at higher level decreased ammonia concentration (P<0.05). Paraserianthes falcataria addition to ammoniated rice straw decreased protozoa population (P<0.05) and S. rarak further decreased the fauna population (P<0.05) as well. Inclusion of S. rarak at 20% DM (T6) produced the lowest methane production both at 24 and 48 h after incubation and lowest methane production per unit of DM degraded. It was concluded that ammoniation of rice straw improved its nutritional quality with lower methane production, and its mixture with P. falcataria and S. rarak further increased the quality and lower the production of methane, respectively.
