“…Ammonium spent sulphite liquor (Salo and Puumala 1978) and spent sulphite liquor (Chang et al 1977), which contain more lignosulphonates than wood molasses have been found to decrease the digestibility of forages and soyabean-alfalfa substrate in vitro. In contrast, relative to cane molasses wood molasses (Masonex) has been found to have positive effect on cellulose digestibility in steers (Crawford et al 1978). The wood molasses used in the present experiment contains, however, more lignosulphonates than Masonex.…”

Abstract. The effect of wood molasses ensiled barley on ration digestibility and nitrogen utilization (Exp. 1 and Exp. 2) and on rumen fermentation and degradation rate in sacco (Exp. 2) was investigated in two experiments. The ration contained 0.9 kg of DM. The proportion of hay was 30 % in Exp. 1 and 40 % in Exp. 2. In Exp. I the experimental diets were dried barley (DB) and barley ensiled with a level of 8 (WMB8) or 16 % (WMBI6) wood molasses of barley DM. In Exp. 2 the diets were dried barley (DB), propionic acid-treated barley (PAB) and barleys ensiled with 0.3 % v/w <7o of AIV II solution (AIVB) or with wood molasses at a level of 12 % of barley DM (WMBI2).The ration digestibility decreased with increasing levels of wood molasses. The difference in DM and organic matter (OM) digestibility was significant (P < 0.05) between DB and WMBI6. Wood molasses tended to decrease the apparent digestibility of crude protein and crude fibre and to increase nitrogen retention. The percentages of nitrogen retained of ingested were in Exp. 1 on DB, WMBB and WMBI6 diets 13.1, 17.8 and 15.8 % and in Exp. 2 on DB, PAB, AIVB and WMBI2 diets 13.8, 13.2, 10.3 and 14.5 %, respectively.After feeding, the concentration of total VFA in the rumen was higher when ensiled barleys were fed. The proportion of propionic acid in the total VFA was greater with DB and PAB than with AIVB and WMBI2 diets (P < 0.01), and butyric acid was correspondingly lower (P < 0.01 and P > 0.05). The proportion of isovaleric and valeric acids was highest on AIVB diet. On DB and PAB diets the ammonia concentration in the rumen decreased after feeding, but on AIVB and WMBI2 diets the highest value was reached 1.5 hours after feeding. The degradation rate of DM and CP as determined by nylon bag method was faster on AIVB and WMBI2 than on DB and PAB diets.

“…The effect of wood molasses was similar that reported by others. Crawford et al (1978) found the feeding value of wood molasses from the Masonite process to be equal to cane molasses at a level of 10 % in the diet. When spent sulphite liquor (SSL) was fed at levels of 8 and 12°/o on DM basis, no differences were detected between SSL groups and the control (Chang et al 1977).…”

Abstract. In two experiments the feeding value for growing cattle of barley ensiled with wood molasses (55 Vo DM) was compared with dried barley (DB) and barley ensiled with AIV 11 solution (AIVB). Wood molasses was applied at levels of 8 (WMB8) The average daily gains of 1107 and 1178 g for DB and WMBB, 1182 and 1129 g for DB and WMBI6 and 1248 and 1251 g for AIVB and WMBI2 were not significantly different. Nor did the groups show any significant differences in feed conversion rate, carcass characteristics and rumen fermentation except the lower (P < 0.05) dressing percentage of the WMBI6 group in Exp. 1. Plasma urea N was higher (P < 0.01) and cholesterol lower (P < 0.01) in the AIVB group than in the WMBI2 group. Plasma concentrations of glucose, alanine aminotransferase, asparte aminotransferase and creatinine did not differ significantly in the different groups.

“…As for the proxy traits, the measurement of SFT and REA was on the 12th rib in most publications except for Murphy & Loerch (1994, 6, 7, 8th rib); Crawford, Anthony, and Harris (1978) and Rossi, Loerch, and Fluharty (2000) who did not define the rib number. The MAR was measured on the 12th rib but was expressed according to different scoring scales depending on the year of publication.…”

The chemical composition of carcasses can be predicted from proxy traits in finishing male beef cattle: A meta-analysis

Management practices can contribute to improving carcass quality if carcass quality could be simply evaluated under a wide range of conditions. The objective of this study was to derive quantitative relationships between the most accurate (but laborious) measurements of carcass chemical composition and proxy traits easily obtainable at slaughter (yield grade, subcutaneous fat thickness, marbling, ribeye area and hot carcass weight) by meta-analysis. Data from 34 publications using male beef cattle were used to develop and validate the models. The breeds were characterized according to origin, rate of maturity, production purpose and frame size. The results indicated that the changes in carcass fat and protein can be predicted from the yield grade or subcutaneous fat thickness, and hot carcass weight, with prediction errors ranging between 9 and 12%. Including the breed characteristics in the models did not improve the fit. The relationships are applicable to group values of male beef cattle having light and fatty carcasses from early-maturing British breeds.
