“…In our study, harvesting at HDM increased the proportion of intact kernels and decreased the KPS compared with LDM. Lower KPS has been associated with lower starch digestibility and milk yield (Ferraretto and Shaver, 2012;Braman and Kurtz, 2015;Salvati et al, 2017).…”

“…In Brazil, pull-type forage harvesters without a kernel processor are still widely used by farmers (Bernardes and Do Rêgo, 2014;Daniel et al, 2019). Pull-type forage harvesters typically result in poor kernel processing and, in turn, lower starch digestibility (Salvati et al, 2017;Ferraretto et al, 2018). Additionally, corn hybrids grown in tropical areas predominantly have a greater proportion of vitreous endosperm, which is also associated with lower starch digestibility (Correa et al, 2002).…”

“…Moreover, the use of other NDF sources would bring other digestible nutrients to the diet and be a confounding factor in the study. The beneficial effects of starch on overall rumen fermentation and microbial protein synthesis are well documented (Beckman and Weiss, 2005;Hristov et al, 2005;Salvati et al, 2021). Recent studies have demonstrated the possibility of maintaining cow performance even when lowering starch content in diets by replacing corn grain by nonforage fiber sources (e.g., beet pulp, wheat middlings; Dann et al, 2014Dann et al, , 2015 by increasing the amount of forage in the diet with the use of brown midrib silage hybrids Lim et al, 2015) or by supplementation of the diet with EEP (Arriola et al, 2017;Tirado-González et al, 2018).…”

The objective of this study was to investigate the effects of supplementation of an exogenous enzyme preparation (EEP) on performance, total-tract digestibility of nutrients, plasma AA profile, and milk fatty acids composition in lactating dairy cows fed a reduced-starch diet compared with a normal-starch diet (i.e., positive control). Forty-eight Holstein cows (28 primiparous and 20 multiparous) were enrolled in a 10-wk randomized complete block design experiment with 16 cows per treatment. Treatments were as follows: (1) normal-starch diet (control) containing (% dry matter basis) 24.8% starch and 33.0% neutral detergent fiber (NDF), (2) reduced-starch diet (RSD) containing 18.4% starch and 39.1% NDF, or (3) RSD supplemented with 10 g/cow per day of an EEP (ENZ). The EEP contained amylolytic and fibrolytic activities and was top-dressed on the total mixed ration at the time of feeding. Compared with normal-starch diet, dry matter intake and milk and energy-corrected milk (ECM) yields were lower (on average by 7.1, 9.5, and 7.2%, respectively) for cows on the RSD treatments. Concentrations, but not yields, of milk fat and total solids were increased by RSD. Energy-corrected milk feed efficiency did not differ among treatments. Totaltract digestibility of NDF tended to increase by RSD treatments. Plasma AA concentrations were not affected by treatment, except that of 3-methylhistidine was increased by ENZ, compared with RSD. Blood glucose concentration tended to be lower in cows on the RSD treatments, but ENZ increased glucose and tended to increase insulin concentrations at 4 h after feeding when compared with RSD. Cows on the RSD treatments had decreased concentrations of de novo fatty acids and tended to have increased concentrations of preformed fatty acids in milk. Overall, decreasing dietary starch concentration by 26% decreased dry matter intake, milk, and ECM yields, but ECM feed efficiency was not different among treatments. The negative effects of reducing dietary starch on production were not attenuated by the EEP.

“…The data on the characteristics of the silages present in Table 1, do not include statistical analysis, but the SPFH increased particles in the 8 mm sieve and, as a consequence, increased the MPL. Salvati et al (2020) evaluated the effect of 3 TLC configurations (6, 12 and 18 mm) in an SPFH with processor roller set to 3-mm gap, and observed the same effect, the increase of the TLC from 6 to 18 mm increased the percentage of particles retained on the 8 mm sieve (56.2% to 63.1%) and MPL (7.7 mm to 10.7 mm). The increase in medium particle size (8 to 19 mm) for WPCS harvested with SPFH is also in agreement with other studies (Andrae et al, 2001;Jonhson et al, 2002).…”
