“…Fecal composition was normal for a cow in this lactation phase and the apparent total tract digestibility of the different nutrients indicates a good level of digestion ( Table 1 ). These apparent total tract digestibility results are comparable to other published work with lactating dairy cattle ( 17 , 41 , 42 ).…”

“…To summarize the findings, for the considered parameters, the common minimum was often recorded between 0800 and 1,200 h, corresponding to a new TMR delivery, and the maximum between 1,800 and 0400 h, starting from 10 to 12 h after new TMR delivery, with some differences between studied parameters. These differences could be related to feeding or ruminating behavior ( 19 , 42 , 47 ).…”

IntroductionThe aim of this study was the evaluation of nutrient excretion patterns in samples of feces collected every 2 h to define the best sampling protocol for estimation of apparent digestibility.MethodsFour multiparous mid-lactation Holstein cows, housed in a tie stall barn and milked twice a day (0800; 1900 h), were enrolled. Dry total mixed ration (TMR) without silages was fed once (0800 h) per day. Feces were sampled every 2 h for 72 h. Each sample was divided in 3 portions: hourly sample sample (8, 10, 12, 14, 16, 18, 20, 22, 00, 2, 4, 6), 8-h composite sample (00–06, 08–14 and 16–22), and a 24-h composite sample. Complete chemical analyses were performed and total tract nutrient digestibility was calculated using undegraded neutral detergent fiber at 240 h of in vitro fermentation (uNDF240h) as a marker. Feeding and rumination patterns were also recorded during the trial.Results and discussionFor some parameters, excretion was not constant throughout the day: neutral detergent fiber (aNDFom), undegraded neutral detergent fiber at 24 h of in vitro fermentation (uNDF24h), uDNF240h, total tract crude protein digestibility (TTCPD), total tract neutral detergent fiber digestibility (TTaNDFomD), total tract potentially degraded neutral detergent fiber at 240 h of in vitro fermentation digestibility (TTpdNDF240hD) with minimal values after new TMR delivery and maximal values 12 h after feed delivery. Feeding and ruminating behavior seemed to have an important role in the excretion pattern, due to the pushing and evacuating effect they have. Considering our results, two fecal samples at 12 and 24 h after the TMR delivery are suggested. For one daily sample, 12 h post time of most stable and constant rumination 0000–0600 h, which is also 8 h post feed delivery is suggested.

“…However, inoculation of Lp A1 in silage resulted in substantial increases in diet DM, OM, and CP digestibilities as compared with control (Lp MTD/1) group. Based on the present results, it is easy to distinguish clearly that the difference in digestibility was caused by the nutritional differences of the silages because a difference in nutrient compositions was observed between 2 silages, particularly the fiber components ( Hosoda et al., 2012 ; Miller et al., 2021 ). This should be explained by the fact that the changes of cell wall structure by Lp A1, increased the potentially degradable fraction of the silage, which dramatically improved the nutrients availability of the silage by ruminants ( Kang et al., 2009 ; Addah et al., 2012 ).…”

“…A negative correlation between NDF content and DMI in dairy cow diets has also been found [28]. Miller et al also reported that cows fed with higher NDF diet consumed less DM than cows fed with lower NDF diet [29]. In general, this observation could be explained by the lower NDF content of PMS30 and PMS40 group compared with Control.…”

Effects of Paper Mulberry Silage on the Growth Performance, Rumen Microbiota and Muscle Fatty Acid Composition in Hu Lambs

et al. 2021

Paper mulberry (Broussonetia papyrifera) is widely ensiled to feed sheep in southwestern China, as unconventional woody forage. Feeding lambs with paper mulberry silage (PMS) may improve certain feeding characteristics, thereby affecting the growth performance and meat quality. The aim of this study is to investigate the effects of four diets of PMS on growth performance, rumen microbial composition, and muscle fatty acids profile in Hu lambs. The results showed that 30% and 40% PMS increased the dry matter intake and average daily gain of Hu lambs compared to the control group. PMS30 and PMS40 increased the content of C24:1, and PMS40 increased the content of C20:5n-3. The content of microbial protein (MCP) was higher in PMS40 than in others, but PMS30 and PMS40 reduced the total volatile fatty acid in rumen. PMS30 significantly increased the ratio of acetic acid to propionic acid. The abundance of ruminal Christensenellaceae_R-7_group and norank_f_Eubacterium_coprostanoligenes_group was significantly higher in PMS30 and PMS40 groups. Moreover, Christensenellaceae_R-7_group had a significant positive correlation with n3-polyunsaturated fatty acid. PMS40 might lead to a relatively high content of unsaturated fatty acids in longissimus dorsi muscle by increasing the relative abundance of Christensenellaceae_R-7_group in rumen.
