Nutrient digestibility, ruminal fermentation, and milk yield in dairy cows fed a blend of essential oils and amylase

Abstract: Two experiments were carried out to evaluate a blend of essential oils (EO) combined with amylase as an alternative to ionophores and its potential for reducing the use of antibiotics in the dairy industry. In experiment 1, 8 rumen-cannulated Holstein cows (576 ± 100 kg of body weight, 146 ± 35 d in milk, and 35.1 ± 4.0 kg/d of milk yield at the start of the experiment) were assigned to a 4 × 4 Latin square experiment with 21-d periods to determine the influence of feed additives on total apparent digestibilit… Show more

“…All samples were analysed for dry matter (DM) by drying in a forced-air oven at 105 C for 2 h (Method 930.15), crude protein (CP) (Method 990.03), ether extract (EE) (Method 920.39), acid detergent fibre (ADF) (Method 973.18), neutral detergent fibre (NDF) (Method 2002.04) according to AOAC (2007). The indigestible ADF (iADF) was used as an internal marker to evaluate total-tract digestibility of DM, CP, EE, NDF, and ADF, calculated using the equations of Silva et al (2018).…”

“…Body condition score development is an important indicator of mobilization and, thus, energy metabolism and ketosis risk in cows (Isensee et al, ). Diets rich in tannins and other phytochemicals like essential oils may have a positive effect on body weight and body condition (Broderick et al, ; Silva et al, ; Tedesco et al, ; Ulger, Onmaz, & Ayasan, ). In contrast, no effect of HFA on BCS was observed in the current study.…”

“…In DF, milk urea was slightly lower in the HFA-100 group, but the effect was not statistically significant (Table 3). Previous reports about the influence of essential oils on milk yields and composition have been inconsistent (Braun, Schrapers, Mahlkow-Nerge, Stumpff, & Rosendahl, 2018;Silva et al, 2018).…”

“…Maize ( Zea mays , L.) silage represents one of the most important forages used for dairy cow feed and beef cattle rations in temperate regions (Grant & Adesogan, ; Marchesini, Serva, Garbin, Mirisola, & Andrighetto, ), owing to its high productivity, ease of ensiling and nutritional profile, including both starch and physically effective fibre (Grant & Ferraretto, ; Khan, Yu, Ali, Cone, & Hendriks, ). For these reasons, it is often included in rations at over 30%–40% of dry matter (DM) and over 50% of a ration's fodder (Castillo‐Lopez et al, ; Grant & Adesogan, ; Silva et al, ).…”
