Thirty multiparous lactating Holstein cows with an average live body weight of 642 ± 21 kg and an average daily milk yield of 30.46 ± 0.59 kg were used in this study. Cows with parities of 2 and 4 were used following their peak period, and were divided into three groups, with ten cows in each group. The control group was fed yellow corn grain rations (YCG), while for the 2nd and 3rd groups, 25 and 50% of YCG was replaced with dry sugar beet pulp (DSBP), denoted as DSBP25 and DSBP50, respectively. The contents of dry matter, organic matter, ether extract, nitrogen-free extract, and fiber carbohydrate in the experimental rations tended to decrease; however, crude protein, crude fiber, ash, and fiber fractions tended to increase in the DSBP25 and DSBP50 groups. Only crude fiber digestibility increased (p < 0.05) in the DSBP rations. Rumen pH value and concentration of ammonia nitrogen (NH3-N) decreased, while the concentration of total volatile fatty acids (TVFAs) increased in the DSBP25 and DSBP50 groups. The concentrations of total protein and globulin in blood plasma were higher (p < 0.05) in DSBP25 and DSBP50 than in YCG. However, plasma albumin concentration, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) activities were lower (p < 0.05) in DSBP50 than in YCG. Milk yield and yield of 4% fat-corrected milk (4% FCM) were higher (p < 0.05) in DSBP25 and DSBP50 than in YCG. Fat, protein, solids not fat (SNF), and total solids (TS) contents in milk increased significantly (p < 0.05) for feeding rations containing DSBP. Feed cost was reduced, but the output of milk yield increased with DSBP. In conclusion, introducing DSBP into the rations of Holstein dairy cows led to significant improvements in their productive performance.

Beet Pulp

Sugar beet pulp (SBP) was used as low value adsorbent for the removal of calcium from hard water. Batch experiments were conducted to determine the factors affecting adsorption of the process such as pH value and Ca concentration. The adsorption equilibrium of Ca2+ by the SBP is reached after 100min and a pseudo second-order kinetic model can describe the adsorption process. The initial concentrations of Ca varied from 927 to 1127mgCa2+/L. A dose of 30g/L sugar beet pulp was sufficient for the optimum removal of calcium. The overall uptake of Ca ions by sugar beet pulp has its maximum at pH=8. The adsorption equilibrium data fitted well with the Langmuir adsorption isotherm equation.

This study deals with effects of pressing of ensiled sugar-beet pulp and of application of a chemical preservative on the quality of fermentation process. The experimental silages had a better sensory evaluation than the control ones. In silages treated chemically with a mixture of acids, statistically significantly (P &lt; 0.01) higher dry matter content, lowest pH value, the value of lactic acid and the lowest content of all acids in dry matter were found after 180 days of storage from the beginning of the experiment. The statistically significantly (P &lt; 0.01) highest lactic acid content (43.39 &plusmn; 1.25 g/kg DM) was determined in the control pressed silage. The highest LA/VFA ratio (1.40 &plusmn; 0.18) was calculated for non-pressed experimental silage (D &ndash; 3 l/t of KEM). As compared with untreated control the highest percentage (P &lt; 0.01) of lactic acid and of all fermentation acids was found out in silage D treated with 3 l/t of KEM (58.18 &plusmn; 0.47 g/kg DM). Undesirable butyric and propionic acids were not found in chemically treated silage samples (C, D, E, F). However, the highest (P &lt; 0.01) contents of butyric acid (26.37 &plusmn; 0.91 g/DM) and propionic acid (4.58 &plusmn; 0.78 g/DM) were measured in untreated non-pressed silage samples (B). The highest (P &lt; 0.01) contents of acetic acid and ethanol were found in control silage samples. The quality of these silages was evaluated as very low. &nbsp;

In this paper, the viability of thermophilic anaerobic co-digestion of exhausted sugar beet pulp (ESBP) and pig manure (PM) was evaluated. The effect of the proportion of ESBP on biogas production was investigated by using a series of lab-scale batch assays, in duplicates. The following five ESBP:PM mixture ratios were studied: 0:100, 10:90, 25:75, 50:50, and 100:0. The highest cumulative methane production (212.4 mL CH4/g VSadded) was reached for the mixture 25:75. The experimental results showed that the increase in the proportion of ESBP in the mixture led to the distortion of the process, due to acidification by the volatile fatty acids generated. Acetic acid was the predominant acid in all the cases, representing more than 78% of the total acidity. Moreover, the results obtained by operating at thermophilic temperatures have been compared with those obtained in a previous study conducted at mesophilic temperatures. The results have shown that in the individual digestion of ESBP, the activity of acetoclastic methanogens was affected in both temperatures, but especially in thermophilic conditions. Thus, the methane produced in the individual thermophilic digestion of ESBP came almost entirely from the activity of hydrogen-utilizing methanogenic archaea.

AbstractTwenty-four Friesian dairy cows were divided into two groups of 12 between 12 and 18 weeks prior to calving and fed to achieve condition scores at calving of 3·2 (F) or 2·3 (T). For the first 11 weeks of lactation, six cows from each group (H) were given daily 9 kg of a high-fat compound (acid ether extract (AEE) 96 g/kg dry matter (DM)), 3 kg molassed sugar-beet pulp and hay ad libitum. The other six cows in each group (L) were given 10 kg of a low-fat compound (AEE 29 g/kg DM), 2 kg sugar-beet pulp and hay ad libitum. Allowances of compound and sugar-beet pulp were designed to provide equal amounts of energy, neutral-detergent fibre and protein. The fat source used in compound H was a calcium salt of palm acid oil (Megalac®).DM intake was not affected by treatment but fat intake was significantly higher on diet H (P < 0·001). Group TH had higher intakes of digestible energy (DE) than group FH (249 v. 229 MJ/day; P < 0·05), but condition at calving did not affect DE intake with diet L (FL = 230, TL = 233 MJ/day). Milk yield was not significantly affected by treatment, although cows in group TL tended to yield less milk than other groups (28·3, 27·3, 28·0 and 24·3 kg/day for FH, FL, TH and TL respectively). The concentration of milk fat was higher and of milk protein lower with diet H compared with diet L (milk fat 48·1, 42·2, 42·9 and 39·6; milk protein 28·0, 31·0, 28·4 and 30·5 g/kg for FH, FL, TH and TL respectively). Loss of condition score was greater for cows in group F (0·65 units) than for those in group T (0·04 units). Within group F, loss of condition tended to be greater with diet L.It is concluded that the increased intake of fat with diet H tended to decrease loss of condition in cows that were fat at calving but increase milk yield in cows that were thin at calving. It also tended to increase milk fat concentration but decreased milk protein concentration.

Sugar beet by-products are a lignocellulosic waste generated from sugar beet industry during the sugar production process and stand out for their high carbon content. Moreover, cow manure (CM) is hugely produced in rural areas and livestock industry, which requires proper disposal. Anaerobic digestion of such organic wastes has shown to be a suitable technology for these wastes valorization and bioenergy production. In this context, the biomethane production from the anaerobic co-digestion of exhausted sugar beet pulp (ESBP) and CM was investigated in this study. Four mixtures (0:100, 50:50, 75:25, and 90:10) of cow manure and sugar beet by-products were evaluated for methane generation by thermophilic batch anaerobic co-digestion assays. The results showed the highest methane production was observed in mixtures with 75% of CM (159.5 mL CH4/g VolatileSolids added). Nevertheless, the hydrolysis was inhibited by volatile fatty acids accumulation in the 0:100 mixture, which refers to the assay without CM addition. The modified Gompertz model was used to fit the experimental results of methane productions and the results of the modeling show a good fit between the estimated and the observed data.

SUMMARYPregnant beef heifers allowed ad libitum access to oat straw were given 2·7 kg molassed sugar-beet pulp alone or with additional dicalcium phosphate or urea or a combination of both materials in a Latin square design involving four feeding periods each of 21 days. Supplementation with urea to increase the total daily intake of digestible crude protein from about 130 to 290 g/day increased straw consumption by 20%. This increased the total intake of metabolizable energy from about 13 to 15 Meal/day. Increasing the total intake of phosphorus from about 6 to about 17 g P/day did not increase straw intake or digestibility or the total intake of metabolizable energy in either the presence or absence of additional urea.Supplementation with urea increased the concentration of urea and glucose in the blood plasma and the concentration of ammonia in the rumen liquor, but did not increase the concentrations or alter the proportions of rumen volatile fatty acids. Addition of urea tended to increase the digestibility of the dry matter and crude fibre of the straw. Phosphorus supplementation increased the concentration of phosphorus in the blood plasma.

Twenty-eight Suffolk-cross male castrated lambs aged 7 to 8 months, initial live weight 36 (s.e. 149) kg were given four diets which contained unground pelleted molassed sugar-beet pulp and rolled barley (940 g/kg, fresh weight basis) in the following proportions either A, 0·8 to 0·2 or B, 0·5 to 0·5, with 60 g soya-bean meal per kg. Diets A and B were offered with or without a yeast culture product Yea-Sacc. Diets zvere offered twice daily to appetite with 100 g hay per head. Yeast culture had no effect on any measurement made (P > 0·05). Lambs given diet B consumed more dry matter (DM), grew faster and had superior food conversion efficiencies (all P < 0·01). Rumen fluid taken 3 h after feeding contained higher concentrations of ammonia (F < 0·01), total volatile fatty acids (F < 0·001) and acetic acid (F < 0·001) in samples from lambs given diet A. Rumen fluid samples collected before the 10·00 h meal, produced more gas from diet A than diet B after 6 and 24 h in vitro incubation (F < 0·001) suggesting the presence of more undigested food. When ground diets were incubated, more gas was produced from diet A after 6h (F < 0·05) but not after 24 h fP > 0·05). It is suggested that diet B supported faster growth of the lambs as a result of faster rate of digestion, higher DM intake and superior food conversion.

Ten dairy cows in early lactation were given five different supplements with grass silage ad libitum according to two 5x5 Latin square designs. The supplements consisted of barley (Ba), unmolassed sugar beet pulp (SBP) and molasses (Mo) on dry matter (DM) basis as follows: (A) Ba 1000g, (B) Ba 667 g and Mo 326 g, (C) Ba 417 g, SBP 410 g and Mo 163 g, (D) SBP 983 g and (E) 656 g SBP and 326 g Mo per kg. The lower fat content of SBP and molasses than of Ba was balanced with rapeseed oil. These supplements were fed at the level of 6 kg DM/d. In addition, 1 kg of rapeseed meal was given as a protein supplement. No differences in silage DM intake between the Ba and SBP supplements were found, but inclusion of a high level of Mo depressed silage and total DM intake. Cows given SBP supplements yielded 1.1kg (P < 0.01) more milk and 32 g (P < 0.05) more protein than those given Ba supplements. Milk fat concentration was lower (P < 0.001) on SBP (46.0 g/kg) than on Ba diets (49.1 g/kg) and thus there was no difference in the yield of fat corrected milk(FCM) and milk fat between the two supplements. Inclusion of 2 kg of DM of More reduced the milk (P < 0.001), FCM, fat and protein yields (P < 0.01) compared to diets without molasses. Supplement C increased (P < 0.05) the milk yield compared to the other diets but the milk composition was not affected. The effect of supplements on the digestibility of the ration was determined using acid insoluble ash as a marker. The apparent digestibility of organic matter averaged 0.743 and was not significantly affected by the diet. Digestibility of neutral detergent fibre was higher (P < 0.001) for SBP diets (0.680) than for Ba diets (0.596). Similar differences were observed in the digestibility of other fibre components. However, the digestibility of the silage was not affected by the treatment. Feeding SBP diets resulted in lower (P < 0.001) digestibility of crude protein than did Ba diets. Metabolizable energy (ME) of SBP diets tended to be used more efficiently for milk synthesis than ME of Ba diets. Inclusion of Mo in Ba or SBP did not reduce the efficiency, although the milk yield was decreased. The passage rate of liquid was determined with CoEDTA and that of particles with Cr-labelled straw. The average mean retention time of liquid ranged from 18.0 to 19.9 h and that of particles from 36.8 to 37.7h. Neither time was affected by the treatment. The passage rate of particles from the rumen ranged from 0.045 to 0.048 and that of liquid from 0.096 to 0.104, irrespective of the diet.

Gut Fermentation

The equid has been estimated to derive 70% of energy from volatile fatty acids (VFA) production. Hind gut fermentation in the equid degrades structural carbohydrates to VFA's that are oxidised by the liver as a source of energy. Maximising this potential source of energy is an important consideration when attempting to improve the utilisation of fibre feeds by the equid. It is generally accepted that the acetate:propionate:butyrate are produced in a ratio of 76:18:5 by horses consuming forage diets (Moore–Colyer 2000). This optimum can be unbalanced by the inclusion of high levels of cereal–based concentrates in the diet. Therefore to maximise hindgut function it is important to maximise the use of high–energy fibrous feeds such as alfalfa and sugar beet pulp (USBP), while reducing the inclusion of concentrate feeds. This experiment sought to determine the effect of feed preparation, namely particle size on VFA profiles from a range of alfalfa : unmolassed sugar beet pulp diets.
