SUMMARYThe objective of the current study was to evaluate the effects of calcium propionate supplementation on rumen fermentation, urinary excretion of purine derivatives (PD) and feed digestibility in the total gastrointestinal tract of steers. Eight ruminally cannulated Simmental steers (462±14 kg) were used in a replicated 4×4 Latin square arrangement of treatments with experimental periods of 21 days. The treatments were: control (without calcium propionate), LCaP (calcium propionate – low), MCaP (calcium propionate – medium) and HCaP (calcium propionate – high) with 100, 200 and 300 g calcium propionate per steer per day. Diet consisted of 0·60 maize stover and 0·40 concentrate (dry matter (DM) basis). DM intake (average 9 kg/day) was restricted to a maximum of 0·90 ofad libitumintake. Ruminal pH (range of 6·7–6·5) linearly (P<0·003) and quadratically (P<0·005) decreased, and total volatile fatty acid (VFA) concentration (range of 64·4–67·1 mm) tended (P<0·087) to increase linearly with rising calcium propionate supplementation. Ratio of acetate to propionate fell linearly (P<0·006) and quadratically (P<0·008) from 3·5 to 2·6 as calcium propionate supplementation increased due to the additional propionate supplementation.In situruminal neutral detergent fibre (NDF) degradation of maize stover and crude protein (CP) degradability of concentrate mix were improved with increasing concentration of calcium propionate. Urinary excretion of PD was linearly (P<0·032) and quadratically (P<0·048) increased with greater calcium propionate supplementation (72, 74, 77 and 76 mmol/day for control, LCaP, MCaP and HCaP, respectively). Similarly, digestibilities of organic matter (OM), NDF and CP in the total tract were also linearly and quadratically improved with increasing calcium propionate. The results indicate that the calcium propionate supplementation potentially improves rumen fermentation and feed digestion in beef cattle. It is speculated that calcium propionate stimulates the digestive microorganisms or enzymes in a dose-dependent manner. In the experimental conditions of the current trial, the optimum calcium propionate dose was about 200 g calcium propionate per steer per day.

Yeast culture (YC) based on Saccharomyces cerevisiae is gaining increasing acceptance as a feed additive for ruminants. Production responses to YC have been reported in growing and lactating animals. It has been suggested that these responses are at least partly due to enhanced microbial growth in and microbial nitrogen flow from the rumen (Williams and Newbold, 1990). The aim of the present study was to investigate the effect of YC on rumen fermentation, microbial growth and liveweight gain in bulls fed isonitrogenous diets containing either urea or soya.Thirty two Limousin cross Friesian bulls (liveweight 344 kg) were allocated to treatments on the basis of previous growth rate and initial liveweight. Animals received mixed diets of barley/urea (92% rolled barley, 5% cane molasses, 1.5% urea and 1.5% minerals/vitamin mix) or barley/soya (86.75% rolled barley, 5% cane molasses, 0.75% urea, 6% soyabean meal and 1.5% minerals/vitamin mix) plus or minus 1.5 kg/ tonne YC (Yea-sacc1026 , Alltech, UK) (Table 1). YC was added to the diet prior to mixing. All rations were offered ad libitum twice daily until slaughter (460 kg). Rumen fluid samples were withdrawn by stomach tube 5 and 10 weeks after the beginning of the trial. The outflow of microbial nitrogen from the rumen was estimated from the appearance of purine derivatives in the urine as described previously (Chen et al., 1990).
