“…The lack of interaction between monensin and tannins on rumen kinetics may indicate independence of these additives. The lack of effect of monensin on rumen kinetics (Tables 4 and 5) was also observed by Perna Junior et al (2017) in Holstein cows. The linear reduction of the RED of DM and NDF (Table 4) was also observed by Perna Junior (2018), although only on the effective degradability of NDF and CP, but not on DM.…”

“…The evaluation of this study found no evidence of possible interaction between monensin and tannins in ruminat feeding. The meta-analyzes of Duffield et al (2008b) and Duffield et al (2012), which evaluated the effects of monensin, have shown a reduction of DMI in dairy and beef cattle, but the studies of Hamilton et al (2010), Mullins et al (2012), Perna Junior et al (2017) as well as the present study, found no effect of monensin on DMI (Table 3). These differences may suggest that the effect might depend on the study.…”

2020) Effect of tannins and monensin on feeding behaviour, feed intake, digestive parameters and microbial efficiency of nellore cowsABSTRACT This study aimed to evaluate the associative effect of monensin and tannins on intake, feeding behaviour, digestibility, rumen kinetics, microbial protein synthesis and nitrogen balance. In a 2 Â 4 factorial arrangement, 8 rumen cannulated Nellore cows were distributed in 2 contemporary 4 Â 4 Latin squares and received 8 diets that differed in the level of tannins (0.00, 0.75, 1.50 and 2.25% DM) and presence of monensin. Monensin was daily administered to each cow in one square (about 32 mg/kg DM). No interaction between monensin and tannins was observed (p > .05). Tannins linearly reduced feed intake, but linearly increased daily eating time (p < .05), although these did not alter the number of meals. Monensin increased CP digestibility by 6% (p ¼ .0387) while tannins linearly reduced digestibility of DM, CP, OM and TDN, whereas the reduction was quadratic for ADF and NDF. Tannins linearly reduced the rumen disappearance rate by linearly reducing both passage and digestion rates. Tannins also linearly reduced urinary urea, though neither additive affected microbial protein synthesis. Monensin reduced the proportion of N excreted in faeces, whereas tannins linearly increased faecal N and linearly reduced both urinary and retained N. Monensin and tannins have shown independent effects on feeding behaviour, feed intake, digestive parameters, microbial protein synthesis and N balance, but they did not improve nutrient usage, although monensin alone has shown to have potential to promote N utilisation. Tannins may play an important role in reducing the excretion of N in urine. HIGHLIGHTSTannins reduce the efficiency of nutrient usage in cattle. Tannins change the pathway of the excretion of the feeding nitrogen. The emission of N 2 O from the urine may be reduced by the use of tannins in cattle feeding. ARTICLE HISTORYpromoting the production of propionate (Duffield et al., 2008a). This may alter the feeding behaviour and reduce DMI by a metabolic-feedback effect. The meta-analysis of Duffield et al. (2012) shows that monensin reduces DMI and improves average daily gain through improvement of feed efficiency. But other studies, such as of Hamilton et al.

“…They consequently result in a high CH 4 production in both species. Studies indicate that the use of saponins in ruminant feed rations may reduce the production of biogenic methane [58][59][60], while [61][62][63] indicate that the inclusion of more digestible forages in ruminant diets may reduce emissions from the ruminant's fermentation. This is in line with the equation (10.18b) suggested by [1]; the digestibility of feed ingested by ruminants plays a key role in the emission factor.…”

Effect of Feed Concentrate Intake on the Environmental Impact of Dairy Cows in an Alpine Mountain Region Including Soil Carbon Sequestration and Effect on Biodiversity

Several studies on the environmental impacts of livestock enterprises are based on the application of life cycle assessments (LCA). In Alpine regions, soil carbon sequestration can play an important role in reducing environmental impacts. However, there is no official methodology to calculate this possible reduction. Biodiversity plays an important role in the Alpine environment and is affected by human activities, such as cattle farming. Our aim was to estimate the carbon footprint (CF) of four different dairy production systems (different in breeds and feeding intensity) by using the LCA approach. The present study included 44 dairy Alpine farms located in the autonomous province of Bolzano in northern Italy. Half of the farms (n = 22) kept Alpine Grey and the other half (n = 22) Brown Swiss cattle. Within breeds, the farms were divided by the amount of concentrated feed per cow and day into high concentrate (HC) and low concentrate (LC). This resulted in 11 Alpine Grey low concentrate (AGLC) farms feeding an average amount of 3.0 kg concentrated feed/cow/day and 11 Alpine Grey high concentrate (AGHC) farms with an average amount of 6.3 kg concentrated feed/cow/day. Eleven farms kept Brown Swiss cows with an average amount of 3.7 kg concentrated feed/cow/day (BSLC) and another 11 farms feeding on average 7.6 kg concentrated feed/cow/day (BSHC). CF for the four systems was estimated using the LCA approach. The functional unit was 1 kg of fat and protein corrected milk (FPCM). Furthermore, two methodologies have been applied to estimate soil carbon sequestration and effect on biodiversity. The system with the lowest environmental impact in terms of CF was BSHC (1.14 kg CO2-eq/kg of FPCM), while the most impactful system was the AGLC group (1.55 kg CO2-eq/kg of FPCM). Including the CF reduction due to soil carbon sequestered from grassland, it decreased differently for the two applied methods. For all four systems, the main factor for CF was enteric emission, while the main pollutant was biogenic CH4. Conversely, AGLC had the lowest impact when the damage to biodiversity was considered (damage score = 0.41/kg of FPCM, damage to ecosystem diversity = 1.78 E-07 species*yr/kg FPCM). In comparison, BSHC had the greatest impact in terms of damage to biodiversity (damage score = 0.56/kg of FPCM, damage to ecosystem diversity = 2.49 E-07 species*yr/kg FPCM). This study indicates the importance of including soil carbon sequestration from grasslands and effects on biodiversity when calculating the environmental performance of dairy farms.

“…The adequacy of diets for the nutritional requirements of food-production animals and the use of feed additives that modify the ruminal environment are common methods used to increase energy retention (Perna et al, 2017) and protein utilization by ruminants (Del Valle et al, 2017). The most used feed additives in animal nutrition are ionophores antibiotics, non-ionophores antibiotics and probiotics (Nicodemo, 2001).…”

Essential oil (EO) from Brazilian red pepper fruit contains compounds with antimicrobial activity, and could be possible substitutes for the antibiotics commonly used in ruminant nutrition. Te objectives of the present study were to evaluate the efects of the Brazilian red pepper fruit EO (Schinus terebinthifolius) as a substitute for monensin on performance, carcass characteristics and meat of lambs fed high concentrate diets. Forty-eight lambs were used, 24 males (20 ½ Dorper × ½ Santa Inês and 4 Santa Inês) and 24 females (24 ½ Dorper × ½ Santa Inês), with 21.54 ± 0.88 kg of initial body weight (BW) and 78 ± 2.4 days of age, in a randomized complete block design. Te experiment lasted 56 days, divided into 2 periods of 28 days each. Te treatments were defned by the inclusion in diets of 8 ppm of monensin (MON), and the doses 0.14% (14EO), 0.28% (28EO) and 0.42% (42EO) of red pepper fruit EO. Te additives were included in a base diet with a 10:90 of forage to concentrate ratio. At the end of 56 days, 32 animals were slaughtered for the measurement of carcass parameters and meat composition. Tere was no interaction among treatments and periods for average daily gain (P = 0.08), DM intake (P = 0.36), feed efciency (P = 0.24) and oocyst of Eimeria ssp. in feces (P = 0.46). Te treatments did not afect (P > 0.05) the average daily gain (ADG), dry matter intake (DMI) and feed efciency. Lambs fed diets containing monensin had less (P < 0.01) oocyst/g compared with the diet 14EO. Tere was no efect of diets on carcass characteristics. Te treatments with higher doses of the Brazilian red pepper fruit EO had reduced mineral content of meat compared to monensin. Te red pepper fruit EO demonstrated the potential to replace monensin in feedlot lambs fed high concentrate diets, maintaining performance and carcass characteristics. However, the monensin has greater capacity to control coccidiosis in feedlot lambs.
