“…Including maize silage in the ration increased forage DM intake by 21% when fed as the sole forage, and 16% when mixed with grass silage. These improvements in forage intake are comparable with responses reported recently for cattle (Juniper et al, 2005;Kirkland and Patterson, 2006), although the intake of maize silage can be up to 60% higher when compared with grass silage of low nutritive value (Burke et al, 2007). Previous studies comparing grass and maize silage in pregnant ewe rations have reported forage intakes which were higher (Crosby et al, 2004), similar (O'Doherty et al, 1997) or lower (Brown and Thomas, 1989) than those in ewes fed maize silage.…”

A study was undertaken to investigate the performance of breeding ewes fed a range of forage and concentrate-based diets in late pregnancy, balanced for supply of metabolizable protein (MP). For the final 6 weeks before lambing, 104 twin-bearing multiparous ewes were offered one of four diets: ad libitum precision-chop grass silage 1 0.55 kg/day concentrates (GS); ad libitum maize silage 1 0.55 kg/day concentrates (MS); a 1 : 1 mixture (on a dry matter (DM) basis) of grass silage and maize silage fed ad libitum 1 0.55 kg/day (GSMS); or 1.55 kg/day concentrates 1 50 g/day chopped barley straw (C). The CP content of the concentrates was varied between treatments (157 to 296 g/kg DM) with the aim of achieving a daily intake of 130 g/day MP across all treatments. Compared with ewes fed GS, forage DM intake was higher ( P , 0.05) in ewes fed MS (10.21 kg/day) and GSMS (10.16 kg/day), resulting in higher ( P , 0.001) total DM intakes with these treatments. C ewes had the lowest total DM intake of all the treatments examined ( P , 0.001). C ewes lost more live weight (LW; P , 0.001) and body condition score (BCS; P , 0.05) during the first 3 weeks of the study but there were no dietary effects on ewe LW or BCS thereafter. The incidence of dystocia was lower ( P , 0.01) in C ewes compared with those offered silage-based diets (7.5% v. 37.4% ewes), and was higher ( P , 0.01) in ewes fed MS compared with GS or GSMS (50.7%, 34.7% and 26.9%, respectively). There were no significant dietary effects on the plasma metabolite concentrations of ewes in late pregnancy, pre-weaning lamb mortality, weaned lamb output per ewe or on lamb growth rate. The results of this study demonstrate that both maize silage and all-concentrate diets can replace grass silage in pregnant ewe rations without impacting on performance, provided the supply of MP is non-limiting. The higher incidence of dystocia in ewes fed maize silage as the sole forage is a concern.

“…Similarly, Dawson (2012) reported that forage type (lupins/triticale silage and grass silage) had no effect on live weight gain, carcass gain or feed efficiency. Kirkland and Patterson (2006) observed that including CS along with grass silage increased feed intake, whereas there was no effect on live weight gain. Dewhurst et al (2009) reported that ruminants consuming legumes had higher T × S = interaction between inoculated treatment and silage type; MDA = malondialdehyde; Cor = cortisol; CK = creatine kinase; SOD = superoxide dismutase; T-AOC = total antioxidative capacity; Car = carbonyl.…”

As lack of forage resource, alternative roughage sources have been developed for ruminant production and their inclusion would exert a great effect on the dietary nutrition, consequently affecting animal performance. Four silages (corn silage (CS), corn stalk silage (SS), inoculated CS and inoculated SS) were separately offered to 60 Bohai Black cattle (15 cattle/group) during a 24-week finishing period, in which the growth performance, carcass trait, beef quality and oxidative stability of steers were determined. Neither silage material nor silage inoculant exerted a significant effect on the growth performance, carcass trait and oxidative stability of beef cattle (P>0.05). As to beef quality, cattle offered CS had higher (P0.05) on the proximate components and fatty acids profile of beef muscle. There was neither an interaction (P>0.05) between inoculated treatment and silage material. There were no differences (P>0.05) in cholesterol content and meat quality traits in animals fed alternative silages. The collective findings suggest that it is not economical to substitute high-quality forage for relative low-quality forage in a high-concentrate finishing ration of beef cattle and silage inoculant inclusion would not exert a direct effect on animal performance.

“…The red clover and corn silages were more typical of these materials in the United Kingdom, with pH and ammonia-N relatively low for the red clover silage (Dewhurst et al, 2003) and the corn silage starch content relatively high (Kirkland and Patterson, 2006). Wholecrop oat silage is not common in the United Kingdom; the material used for this study contained more NDF and starch and less CP than spring-sown oat silages used in Canada (Khorasani et al, 1993(Khorasani et al, , 1997.…”

Nine multiparous Holstein-Friesian cows (initially 97 d in milk), were used in a 3×3 lattice square design experiment with 4-wk periods. All cows received 4 kg/d concentrates and dietary treatments were based on silages offered ad libitum: perennial ryegrass (PRG); timothy (TIM); tall fescue (TF); red clover (RC); red clover/corn silage mixture [40/60 on a dry matter (DM) basis; RCC]; red clover/whole-crop oat silage mixture (40/60 on a DM basis; RCO); or red clover/whole-crop oat silage mixture (25/75 on a DM basis; ORC). The remaining treatments were based on RCO with feed intake restricted to the level of PRG (RCOr) or with a low protein concentrate (50/50 mixture of barley and molassed sugar beet pulp; RCOlp). Experiment objectives were to evaluate diet effects on N partitioning and N isotopic fractionation. Yields of milk and milk protein were consistently high for diets RC, RCC, and RCO and low for the diets based on poorly ensiled grass silages. Restriction of intake (RCOr) and inclusion of a higher proportion of whole-crop oat silage (ORC) and the low-protein concentrate (RCOlp) led to some loss of production. Diet had little effect on milk fat, protein, and lactose concentrations: low concentrations of milk protein and lactose reflect the restricted energy intakes for all treatments. The highest diet digestibilities were measured for RC and PRG, whereas increasing inclusion of the whole-crop oat silage (0, 60, and 75% of forage DM) led to a marked decrease in diet digestibility (0.717, 0.624, and 0.574 g/g, respectively). Urinary excretion of purine derivatives, an indicator for rumen microbial protein synthesis, was significantly higher for RCC than for TIM and TF. Nitrogen intake ranged between 359 and 626 g/d (treatment means). Partitioning of N intake to feces and urine was closely related to N intake, although urinary N losses were less than predicted from N intake for the 60/40 mixtures of cereal silage and red clover silage. The 15N content of milk, urine, and feces were all influenced by diet 15N content. Isotopic fractionation meant that feces and milk were enriched and urine was depleted in 15N relative to the diet. Significant relationships were observed between the extent of enrichment of urine, feces, and milk, suggesting some commonality in fractionation pathways. The trend for the lowest 15N enrichment in milk protein occurring in diets with low N-use efficiency (milk N/feed N) was contrary to expectations, possibly because of endogenous contributions to milk protein or fractionation when dietary ammonia was incorporated into microbial protein.
