“…While eating, cows are unable to ruminate (Van Soest, 1994); a comparison between Figures 3 and 4 shows that the rumination peaks indeed appeared at least an hour after the eating peaks during the daytime, and also during the nighttime hours (2400 to 0600 h) when cows were not eating. A similar distribution of eating peaks was also demonstrated in previous studies (Miron et al, 2003;Adin et al, 2008).…”

“…These differences in TMR ingredients and their chemical compositions (Tables 1 and 2), were expressed in a greater intake per meal (by 13.3%, P = 0.03), a higher rate of meal consumption (by 23.2%, P = 0.02), a similar number of meals per day (7.92 and 8.35), a shorter daily eating duration (by 13%, P = 0.05), and a greater total daily DMI (by 7.2%, P = 0.02) in the EXP cows as compared with the CON cows (Table 3). Similar effects on rate of eating and daily DMI were obtained in previous studies that used soyhulls as a partial roughage replacement in TMR of midlactating cows (Miron et al, 2003(Miron et al, , 2008Adin et al 2008). Improvement of DMI in a similar feeding system was shown also by Weidner and Grant (1994).…”

“…Recently, we suggested increasing the voluntary energy consumption of the lactating cow by replacing part of the dietary roughage component with by-products rich in readily digestible NDF, such as soyhulls (Miron et al, 2003). In previous studies (Miron et al, 2003(Miron et al, , 2008Adin et al, 2008), we demonstrated that feed-ing dairy cows with soyhulls during midlactation as a partial roughage replacement increased DMI by 6.9% and milk yield by 5.5% (P < 0.05). However, there is a lack of knowledge on how the cow would respond to such a diet during the early stage of lactation.…”

This study measured the effects of including soyhulls as partial roughage replacement in total mixed rations (TMR) fed to 25 pairs of cows during early lactation, on the dry matter (DM) intake, particle kinetics, rumination, in vivo DM and NDF digestibility, milk and FCM yields, and BW changes. The 2 diets used in this study differed in the content of roughage and roughage NDF [23.5 vs. 35.0%, and 12.8 vs. 18.7% in the experimental (EXP) and control (CON) TMR, respectively]. The EXP TMR contained 20.5% less physically effective NDF than the CON TMR (11.7 vs. 14.1% of DM, respectively). These differences were expressed in a greater intake per meal (by 13.3%), a higher rate of meal intake (by 23.2%), a similar number of meals per day, a shorter daily eating duration (by 13%), and a higher total daily DMI (by 7.2%) in the EXP cows as compared with the CON cows. The in vivo DM and NDF digestibility was higher by 4.9 and 22.7%, respectively, in the EXP cows than in the CON cows. The rumination time for the TMR in the EXP cows was 12.7% (54.3 min/d) shorter than in the CON cows, and this was probably related to the difference of 12.4% in physically effective NDF intake between the 2 groups. Patterns of daily rumination and feed consumption throughout an average day showed a delay of approximately 1 to 2 h between the eating and rumination peaks. Particle flow from the rumen of the EXP cows was characterized by a longer rumen mean retention time (by 17.8%) and longer rumination time per kilogram of roughage ingested (by 23.5%) as compared with the CON cows. Thus, favorable conditions for NDF digestion were created in the rumen of the EXP cows, as reflected in their rumen pH values (6.67). The advantage of the EXP cows in intake and digestibility was reflected in a concomitant increase of 7.4% in milk production and of 9.2% in FCM yield as compared with the CON cows. No difference was found between the 2 groups with respect to efficiency of feed utilization for milk production and BW changes.

“…The farmer needs useful and practical information about the incidence of calving disease in the farm. In the past researchers demonstrated the positive relationship between NDF intake and RT and showed that reduced feed intake in late pregnancy increased the risk of calving diseases (Kim and Suh, 2003;Urton et al, 2005;Adin et al, 2008;Trevisi et al, 2010a). Our hypothesis is that cows with reduced RT before and after calving would be at greater risk to suffer from one of the calving diseases.…”

The main objective of this experiment was to monitor the rumination pattern during the transition period in primiparous (PR) and pluriparous (PL) dairy cows and to investigate its relationships with metabolic conditions, milk yield, and health status. The study was carried out in an experimental free-stall barn and involved 32 Italian Friesian cows (9 PR and 23 PL) during the transition phase. The rumination time (RT) was recorded with an automatic system (HR-Tag), and data were calculated and summarized in 2-h intervals. Blood samples were collected during the transition phase to assess biochemical variables related to energy, protein, and mineral metabolism, as well as markers of inflammatory conditions and some enzyme activity. Daily milk yield, BW, nutritional condition, and health status were also recorded. The average RT before calving (-20 to -6 d) was 463 min/d in PR (range 270 to 620) and 522 min/d in PL (range 411 to 640). In the early lactation [15 to 40 d in milk (DIM)], the average RT was 504 min/d in PR (range 400 to 585) and 562 min/d in PL (range 414 to 685) and was positively correlated with milk yield (r = 0.36; P < 0.001). The RT reached the minimum at calving d (262 min/d in PR and 278 min/d in PL). Before calving the percentage of RT during the nighttime was 60% in PR and 62% in PL, whereas the values decreased after calving (55% in PR and 57% in PL). During the first weeks of lactation, PR showed a shorter RT than PL in the 2-h intervals that included milkings. Cows with reduced RT before calving maintained reduced RT after calving and suffered a greater frequency of disease than cows with greater RT in late pregnancy. Moreover, cows characterized by mild inflammatory conditions and without health disorders or only mild health disorders during the puerperium showed a greater average rumination time (over 520 min/d) during the first 10 d of lactation. Conversely, the decreased RT (450 min/d) during the first few days of lactation was observed in cows with subclinical diseases or health disorders. Cows affected by clinical mastitis during the trial showed a reduction of RT and a change in its variability already some days before the drug treatment. Our results suggest that the automatic measurement of RT is useful to predict calving time and to quickly obtain information on health status of the animals in a period as critical as the transition phase.

“…Eff ect of diff erent amount of roughage neutral detergent fi ber (NDF) in feeding ration on milk yield was evaluated by Adin et al, (2008) Lower content of roughage NDF (12 %) with soy hulls addition increased milk yield from 32.2 to 34.6 kg and sti mula ted also milk protein production. According to Sinclair et al, (2003), fermented whole crop wheat can provide a comparable milk production to good quality grass silage and the harvesting at a later stage of maturity had negligible eff ect on milk production, although milk protein levels tended to be higher in cows fed feedstuff containing higher starch content.…”

Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 5, pp. 369-376 The aim of this study was to evaluate the possible eff ects of maize replacement in feeding rations on the amino acid content in cows´ milk. Cows were fed total mix ration based on the maize, clover silage and hay. There was a diff erence in the concentrate of the feeding ration. The fi rst group (fed maize) was the control group, another two groups were experimental, one fed wheat and second fed triticale. During six weeks, totally 26 milk samples were taken from dairy cows of Czech Pied breed. Feed groups were preferably balanced in terms of milk yield, stage and number of lactations. The samples of feedstuff s as well as milk were modifi ed for the analysis using acidic and oxidative hydrolyses. The analysis of amino acids content and composition of the sample hydrolysates was performed chromatographically by an AAA 400 analyzer, using Na-citrate buff ers and ninhydrin detection. Total nitrogen content was determined according to Kjehldahl and the crude protein of the samples was determined by conversion from the nitrogen content multiplied by appropriate factor. The high content of crude protein in wheat did not infl uenced composition of milk from dairy cows fed this type of feedstuff . With respect to resulting amino acid content and composition of milk samples, none of the tested grains can be re com men ded as a full-value maize replacement. Each feedstuff is an abundant source of several and ty pi cal amino acids in milk. However, triticale (cultivar Kitaro) seems to be acceptable replacement of maize owing to better crude protein effi ciency, composition and health indicators of milk quality. dairy cow, maize, wheat, triticale, amino acids
