“…, 2008). In Canterbury, New Zealand, soil Olsen P (11 and 20 mg/L) had no effect on individual lamb LWG and clover content of irrigated swards, but increased P contents in ryegrass (0.36–0.45%) and clover (0.34–0.36%) herbage and LWG in kg/ha/yr over 3 yrs (Black et al. , 2007).…”

Phosphorus is essential for plant and animal health. The aim was to determine the impacts of P fertilizer on changes in Morgan's soil test P (STP) and liveweight gain (LWG) of mature beef animals over the last 10 yrs (1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008) of a 40 yr P experiment on temperate permanent grassland in northwestern Europe. There were three original treatments: 0 (P0), 15 (P15) and 30 (P30) kg ⁄ ha ⁄ yr P for 40 yrs , and three new treatments on the same area that started in 1999: P0 for 30 yrs then 30 kg P ⁄ ha ⁄ yr for 10 yrs (P0-30), P15 then 5 kg P ⁄ ha ⁄ yr (P15-5) and P30 then zero P (P30-0). Six plots (0.18 0.27 ha) per treatment were rotationally grazed by beef animals from April to October. The STP levels on the three original treatments were stable over the last 10 yrs and averaged 2.4 (P0), 5.8 (P15) and 16.0 (P30) mg ⁄ L soil. The STP decreased from 18.0 to 8.5 mg ⁄ L in the P30-0 treatment, from 6.5 to 5.0 mg ⁄ L in the P15-5 treatment and increased from 2.4 to 4.8 mg ⁄ L in the P0-30 treatment. Liveweight gains were lowest on P0 but similar on the other treatments (mean of 651 compared to 988 kg ⁄ ha ⁄ yr). It is concluded that of the order of 4-6 mg ⁄ L STP and a fertilizer input of 810 kg ⁄ ha ⁄ yr P was adequate for beef production on a grazing system under the conditions of this experiment.

“…The advantage of Caucasian clover (Trifolium ambiguum; CC) over traditional legumes has been illustrated in a number of animal and pasture production studies (Taylor & Smith 1998). For example, at an irrigated lowland site in Canterbury, Black et al (2007) reported greater liveweight gain for lambs grazing mixed CC-ryegrass (Lolium perenne; RG) pastures than white clover (T. repens; WC)-RG pastures. Similarly, in Wisconsin, USA, Mouriño et al (2003) showed that the liveweight gain of steers on CC-grass pastures was 20% greater than on red clover (T. pratense)-grass pastures.…”

Dry matter yield of dryland and irrigated mixtures of Caucasian clover, white clover and perennial ryegrass over 5 years at Lincoln University

This experiment investigated the effects of Caucasian clover (CC), white clover (WC), perennial ryegrass (RG) and their mixtures on dry matter (DM) yield under dryland and irrigated conditions over 5 years (1st July-30th June) at Lincoln University. Seven mixtures of the three species (three pure, three binary and one ternary) were sown in November 1999, grown with and without irrigation, and grazed by sheep. Total annual DM yield in Years 2-6 (2000/2001-2004/2005) was analysed. Clover-RG mixtures yielded more than the average monoculture yields of their constituent species (over-yielding). This diversity effect was 1.8-7.0 t DM/ha for WC-RG over all 5 years and 2.7-4.6 t DM/ ha for CC-RG in Years 3-6. There was no additional yield benefit from the three-species mixture. Diversity effects were due to synergistic interactions between the clovers and RG, which were similar for CC and WC once established. The interspecific interactions persisted despite changes in botanical composition across irrigation levels and years.

Intake and performance of sheep or cattle grazing legume-based swards were assessed over 2 years at four locations in Europe with different climatic conditions: Sardinia (Italy), southern France, northern Germany and south-west England (UK). Legume species were sown in mixtures with locally appropriate companion grass species. Standard legume species commonly used at the location (Medicago polymorpha in Italy, Medicago sativa in France, and Trifolium repens in Germany and UK) were compared with two alternative legume species characterized by different agronomic or nutritional characteristics. They were: Trifolium subterraneum and Hedysarum coronarium in Italy; Trifolium incarnatum and Onobrychis sativa in France; Trifolium pratense and Lotus corniculatus in Germany; and Trifolium ambiguum and L. corniculatus in the UK. Lactating milk sheep in Italy, non-lactating ewes in southern France, growing cattle in Germany, and ewes and lambs in the UK were used in three replicates per treatment. Intake and performance of sheep and cattle in various treatments varied with location, year and period within year. In Germany, intake and performance by cattle were not affected by treatment. In contrast, at the other locations, sheep grazing standard or alternative legume species known to contain condensed tannins (sulla, sainfoin and birdsfoot trefoil) had higher proportions of legume and crude protein (CP) concentrations in the diet and higher CP intakes than those grazing the other alternative legume species. Sheep performance paralleled these results. It is concluded that there is potential for a greater use of alternative legume species, at least for sheep-grazing systems, in both the Mediterranean and cool temperate zones of Europe.
