“…The supplementation of tannins did not change (P>0.05) the in vitro ammoniacal nitrogen content (NH 3 -N) of all the feedstuffs (Table 5). This is consistent with previous studies that have reported no significant effect of tannin supplementation on ammoniacal nitrogen content (Martello et al, 2020).The fitted models consisted of combinations of Eq. ( 1) with the variance functions described by equations Eq.…”

The objective of this study was to evaluate the effects of the daily supplementation with a low dosage of a blend of condensed and hydrolysable tannins on the in vitro and in situ digestibility of protein and fibrous feedstuffs. In situ ruminal incubation assays were conducted on seven protein and five roughage feedstuffs with and without tannin supplementation (1 g/kg DM intake). From these same cattle, rumen fluid was collected for in vitro incubations of the same feedstuffs. In vitro assays we evaluated the gas production (GP) up to 24 h and, sequentially, digestibility of dry matter (IVDMD), crude protein (IVCPD), fiber (IVNDFD), and ammonia nitrogen (NH3-N). For in situ assays, the disappearance curves were modeled and then the potentially degradable (), digestion rate (), and undegradable () fractions were estimated. Of all the variables studied, only IVCPD of soybean meal showed effect (P<0.05) with the addition of dose of tannins. The supplementation of tannin affected only of the DM and CP of the cottonseed meal. The of DM and CP increased with the supplementation of the tannin blend only for Marandu (dry season), soybean and cottonseed meal. Additionally, the of the DM of corn silage was reduced. The of CP was affected by the increase of tannin supplementation for soybean and cottonseed meal. Daily supplementation with a low dose of tannin blend for grazing cattle affects for grazing cattle affects the ruminal digestibility of some of the evaluated feedstuffs, which are soybean and cottonseed meal.

“…However, the effect of tannin types may compromise microbial digestion of fibrous materials. Therefore, the addition of tannins as a dietary supplement has been mainly studied to increase the supply of metabolizable protein to grazing ruminants without negatively affecting ruminal fiber digestion (Martello et al, 2020;Cidrini et al, 2022).…”

“…In addition, the tannin content of the four alfalfa varieties was possibly due to enhancing nitrogen utilization in animals when added to feedstuffs. Martello et al (2020) found that beef cattle were reared in 0.25 ha (per head) of Urochloa brizantha cv. Marandu found increased CP digestibility when of 0.1% in blend tannin (85% of CT and 15% of HT) and in dietary DM (10 g/head/day) together with 2% of urea in the DM.…”

This study proposed to examine the alfalfa varieties suitable for further field experiments in Sa Kaeo province in order to cultivate alfalfa plants for a meat goat diet. Four varieties of alfalfa were collected from four distributors, source from the Republic of Turkey (coded as AC1), source from the United Kingdom (coded as AC2) and source from the United States of America (coded as AC3 and AC4, respectively). Their growth rate, yield and chemical composition were analysed in Sa Kaeo province. The results show that the plant height, the number of leaves per plant and the leaf width increased from 30 to 90 days after all the varieties were planted. There were significant differences between the varieties in their chemical composition after the first (90 days) and second (120 days) harvest times except for dry matter (DM) 90 days after planting. To determine the effects of increasing levels of alfalfa dehydrated pellets (ADP) in total mixed ration (TMR) on feed intake and productive performance of meat goat, a randomized complete block design experiment was conducted with 9 crossbred Native-Anglo Nubian goats, 3-4 months’ old, with body weight ranging from 8-10 kg which were fed received 0%, 10% and 20% of ADP in a TMR. The results revealed that increasing levels of ADP with 10% and 20% in the diet had no effect on DM intake, average daily gain, nutrient digestibility and blood urea nitrogen.

“…(kg/day) (Table 5), which was slightly superior when compared to findings by Fernandes (2019), who had beef cattle submitted to grazing (Urochloa brizantha) systems during dry and rainy season, with overall DMI average of 6.15 (kg/day). Martello et al (2020) found a much lower feed intake for forage DMI of 4.56 (kg/day) for cannulated Nellore cattle allocated in grazing system in Urochloa brizantha pastures.…”
