Wet Distiller's Grains

SUMMARYTwelve British Friesian and 12 Ayrshire castrated male calves were fed ad libitum one of three complete diets of differing energy concentration from approximately 140 to 410 kg live weight. Differences in energy concentration of the diets were achieved by inclusion of different proportions of wet distiller's grains (WDG). Increasing the proportion of WDG in the diet caused reductions in performance. This effect was more marked with the Friesians than with the Ayrshires. The treatments had small and generally non-significant effects on carcass conformation and composition.

Wet Distiller's Grains

SUMMARY1. Weaned single-suckled calves (castrates) were housed at 260·7 kg live weight. Six genotypes, all two- or three-way crossbreds, were represented. A diet of bruised barley, wet distiller's grains, swedes and grass silage was offered until the required minimum live weight (363 kg) and body composition was reached. The cattle were then slaughtered (treatment A), or retained for 8 (treatment B) or 16 weeks (treatment C). During the period when treatment B and C animals were retained their diet was 53% bruised barley and 47% wet distiller's grains offered ad libitum.2. Live weights at slaughter were 418·2, 458·6 and 496·1 kg (P < 0·001), carcass weights 240·5, 266·2 and 295·7 kg (P < 0·001), and killing-out percentages 57·5, 58·1 and 59·6 (P<0·01) for treatments A, B and C respectively. Daily live-weight gain did not decline during the 8 or 16 weeks cattle were retained on treatments B and C.3. Retaining the cattle to slaughter points B and C caused increases in the percentage of low-value joints in the carcass, carcass fat percentage, dry matter and fat contents of the dissected m. longissimus dorsi; and decreases in the percentage of high-value joints, carcass lean and bone percentage, crude protein and ash contents of m. longissimus dorsi. The carcass composition was 55·6, 53·5 and 51·4% lean (P<0·001); 30·7, 33·3 and 36·2% fat (P<0·001); 13·7, 13·2 and 12·4% bone (P< 0·001) for treatments A, B and C respectively.4. The results are discussed in relation to the choice made by beef producers between slaughter and retention of cattle which have reached suitable live weight and condition for marketing.

Effect Of Feeding

SUMMARY1. Two experiments are described in which castrated Ayrshire cattle were reared on a conventional all-concentrate diet to 250 kg live weight. In Experiment 1 the effect of feeding a 1: 1 mixture (by weight) of barley and wet distiller's grains (WDG) from 250 to 408 kg live weight was examined. In Experiment 2 swedes and grass silage were offered in addition to WDG and barley during the growth phase from 250 kg live weight to slaughter. In both experiments a control group was fed an all-concentrate diet.2. The introduction of WDG to the diet (Experiment 1) caused a significantly lower daily live-weight gain (P < 0·01) and an increase i n time to slaughter (P < 0·01). Carcasses from the control and treated animals were similar in weight, conformation and composition. There were no differences in growth rates in Experiment 2. The treated animals were heavier (P < 0·01) and older at slaughter (P < 0·001) than those in the control group and they produced heavier carcasses (P < 0·05). The carcasses were similar in composition but some differences in conformation occurred. These effects were the consequence of selecting animals for slaughter on the basis of equal finish (i.e. the ratio of muscle plus fat to bone assessed subjectively).3. The effect of reducing the dietary energy concentration appears t o be smaller with cattle over 250 kg live weight than with younger, lighter cattle. The results, which are discussed in economic terms, suggest that castrated Ayrshire cattle reared on all-concentrate diets should be changed to a diet of lower energy concentration using cheaper feed sources at 250 kg live weight.

In Vitro Rumen Fermentation

Abstract Two sets of in vitro rumen fermentation experiments were conducted to determine effects of diets that included wet distiller’s grains plus solubles (WDGS) and tannin-rich peanut skin (PS) on the in vitro digestibility, greenhouse gas (GHG) and other gas emissions, fermentation rate, and microbial changes. The objectives were to assess associative effects of various levels of PS or WDGS on the in vitro digestibility, GHG and other gas emissions, fermentation rate, and microbial changes in the rumen. All gases were collected using an ANKOM Gas Production system for methane (CH4), carbon dioxide (CO2), nitrous oxide (N2O), and hydrogen sulfide (H2S) analyses. Cumulative ruminal gas production was determined using 250 mL ANKOM sampling bottles containing 50 mL of ruminal fluid (pH 5.8), 40 mL of artificial saliva (pH 6.8), and 6 g of mixed diets after a maximum of 24 h of incubation. Fermenters were flushed with CO2 gas and held at 39 °C in a shaking incubator for 24 h. Triplicate quantitative real-time polymerase chain reaction (qPCR) analyses were conducted to determine microbial diversity. When WDGS was supplied in the diet, in the absence of PS, cumulative CH4 production increased (P < 0.05) with 40% WDGS. In the presence of PS, production of CH4 was reduced but the reduction was less at 40% WDGS. In the presence of PS, ruminal lactate, succinate, and acetate/propionate (A/P) ratio tended to be less with a WDGS interaction (P < 0.01). In the presence of PS and with 40% WDGS, average populations of Bacteroidetes, total methanogens, Methanobrevibacter sp. AbM4, and total protozoa were less. The population of total methanogens (R2 = 0.57; P < 0.01), Firmicutes (R2 = 0.46: P < 0.05), and Firmicutes/Bacteroidetes (F/B) ratio (R2 = 0.46; P < 0.03) were strongly correlated with ruminal CH4 production. Therefore, there was an associative effect of tannin-rich PS and WDGS, which suppressed methanogenesis both directly and indirectly by modifying populations of ruminal methanogens.
