“…In recent decades, much research has been carried out concerning the effects of molasses inclusion or feed based on molasses on dairy cattle [ 35 , 36 , 37 , 38 , 39 , 40 ]. However, the results do not always agree since they are often influenced by both the different diets and the different amounts of molasses used.…”

“…In a recent study, de Ondarza et al [ 39 ] analyzed 24 research using a mixed model linear regression analysis. They considered different levels of sugars added in the rations (control, 1.5–3%, 3–5% and 5–7% of DM), days in milk category (within treatment), control milk yield category (within treatment), and several continuous nutrient variables.…”

“…According to experts [ 28 ], the advantages of molasses in dairy cow feeding can be summarized as follows: (a) increased availability of net energy and digestible protein; (b) increased dry matter intake, milk production, lactation curve persistency and milk fat content; (c) improved fiber digestion and nutritional efficiency; (d) reduction in the risk of subclinical acidosis and rumen sub-acidosis, mucosa damage and innate immune system stimuli, and (e) a reduction in the weight loss of lactating subjects and a decrease in the incidence of ketosis. It is necessary to limit the daily intake of molasses to values below 10% (6.75% of diet DM; [ 39 ]). In practice, it is suggested to not exceed 1 kg/head/day for beef cattle and 0.5, 1, 1.5 kg/head/day in heifers and in dry and lactating cows, respectively.…”

In the past fifty years, agriculture, and particularly livestock production, has become more resource-intensive, with negative implications regarding world environmental status. Currently, the circular economy 3R principles (to reduce, reuse and recycle materials) can offer many opportunities for the agri-food industry to become more resource-efficient. The closed-loop agri-food supply chain has the great potential of reducing environmental and economic costs, which result from food waste disposal. To meet these principles, the use of crop byproducts, such as molasses, in animal nutrition improves the nutritive value of coarse and poorly desired feedstuff, which could present a real opportunity. The aims of this study were to summarize the possible applications of molasses for animal nutrition, to improve hay and silage quality for beef and dairy cattle, to enhance industrial byproduct values using liquid feed in swine production, and to improve extensive livestock production with feed blocks. The study focused on both feed characteristics, based on molasses, and on ruminal fermentation of its carbohydrates; the techniques of the production, conservation and administration of molasses to animals have been widely described as being capable of positively influencing animal performance, milk and meat quality.

“…Several studies reported that molasses addition would reduce cow sorting activity (DeVries and Gill 2012), stimulate DMI due to a sweetening effect (Murphy et al 1997), increase butyrate production (DeFrain et al 2004(DeFrain et al , 2006Chibisa et al 2015;Oba et al 2015), and affect milk fat, FCM, ruminal ammonia, MUN, and fibre digestibility (Broderick and Radloff 2004;Brito et al 2015). Overall, molasses could be added to the diets in substitution of starch sources, due to a different impact on rumen fermentations and pH (Oelker et al 2009;Brito et al 2017;De Ondarza et al 2017), effect related to their sugar fraction composition. Molasses contain mono-di-, and tri-saccharides, composed by hexoses, as well as pentoses in traces (Palmonari et al 2020).…”

Beet and cane molasses mainly contain mono-di-, and tri-saccharides, composed by hexoses, as well as pentoses in traces. However, rationing software consider sugars as only one entity, with a rate of digestion $20% h À1 . The aim of this initial study was to investigate and evaluate the in vitro digestion dynamics and rates of the sugar fraction in molasses. Three beet and three cane molasses were randomly selected from a variety of samples collected world-wide and digested via in vitro rumen fermentation, at 1, 2, 3, 4, 6, 8, and 24 h. Samples were then analysed with a specific enzymatic kit to quantify residual sucrose, glucose, fructose, raffinose, galactose, and arabinose. Complete disappearance of sucrose happened within 3 hours of incubation. Glucose and fructose were completely digested within 4-6 h, showing variability among samples. Even if not so representative, galactose showed a similar trend of digestion (97% digestion within 3-4 h). Raffinose was quite slower in cane molasses, while it was completely digested within 1 h in beet molasses. Arabinose, a pentose, never reached a complete digestion, and its fermentation dynamic was different compared to other sugars. Calculated rates of digestion for sucrose, glucose and fructose, most representative sugars in molasses, were higher than 50% h À1 in both cane and beet. Obtained results showed that sugar fraction in molasses may vary, and different sugars are rapidly fermented by rumen microbes. Modern rationing models should consider a modification of sugar rates of digestion, since the actual one appears too slow than those observed in vitro. HIGHLIGHTS Molasses are unique blends of several sugars Major sugars are digested in few hours Rationing software should consider a faster rate of digestion for different sugars ARTICLE HISTORY

“…Another factor that affects the length of rumination is lying time (Schirmann et al, 2012) and heat time (Reith and Hoy, 2012;Mičiaková et al, 2018). According to de Ondarza et al (2017) changes in rumination time may indicate health problem earlier than clinical changes occur and before decrease of milk production. Optimal rumination time in cattle should be in range of 8 to 10 hours, eventually 12 hour a day in 4 to 20 time intervals that last from 10 to 60 minutes (Gáspárdy et al, 2014;Liboreiro et al, 2015).…”

Rumination time is one of possible parameters for observing not only feed management and health status, but also some reproductive characteristics such as heat or periparturient period. The evaluation of rumination time in this study was done on Holstein dairy cows in period around heat (n = 297) and around parturition (n = 322) during one year. SAS 9.3 was used for statistic evaluation. Factors such as heat or periparturient period but also a parity or month within the year have significant impact on rumination time. The decrease of rumination time in the average of 19% (more than 100 minutes) was observed in heat time against days before heat. Similarly, decrease of rumination time more than 110 minutes was observed on the day of parturition in comparison with days before that day. However, the return to normal rumination time values was gradual within 3 day after calving. The results indicated that in healthy cows the rumination time can be a good indicator not only of approaching periparturient but also of incoming heat.
