Abstract White clover can reduce fertilizer‐N requirements, improve sward nutritive value and increase environmental sustainability of grazed grasslands. Results previous experiments in glasshouse conditions on mown plots have suggested that white may be more susceptible than perennial ryegrass to treading damage wet soils. However, this phenomenon has not been investigated under actual grazing conditions. This experiment examined the effects content, herbage production soil properties...
Abstract Two field experiments were conducted at Teagasc, Moorepark, Ireland, to determine the effect of sowing date and nitrogen application on dry‐matter (DM) yield crude protein (CP) content forage rape stubble turnips. The first experiment consisted three dates (1 August, 15 August 31 August) with four rates fertilizer N (0, 40, 80 120 kg ha −1 ) DM yields. second over two soil sites (fertile or depleted) turnip A delay in from 1 characterized a 74·5% decrease yield, while decreased by...
Abstract The effects on the performance of dairy cows offered kale, swedes, and perennial ryegrass in situ silage fed indoors to pre‐partum during winter Ireland was examined. Eighty‐eight spring‐calving were randomly assigned one four treatments; (i) 8 kg dry matter (DM) kale leaf stem + 4 DM (treatment K), (ii) root swedes S), (iii) 12 herbage G) (iv) ad libitum ID). Cows treatments K, S ID had a greater ( P < 0·001) increase body condition score (0·20, 0·14 0·50 units respectively)...
Abstract Sixty multiparous, Holstein–Friesian pregnant dry dairy cows were allocated to three forage treatments ( n = 20; fodder beet, kale or grass silage) at two feeding allowances 30; high and low) for 70 (s.e. of mean, 16) d before parturition. Cows offered the allowance 9 kg matter (DM) beet grazed in situ plus 5 DM baled silage daily clamp ad libitum indoors. low 6 3·5 daily, 9·5 After calving, all received a 14 perennial ryegrass herbage pasture 4 concentrate cow −1 first 35...
Abstract Semi-natural grassland habitats have declined significantly throughout Europe. To halt the decline, conservation measures been included in most European agri-environment schemes. This is first study to compare botanical composition of managed under Irish Agri-Environment Options Scheme (AEOS). Sixty fields on drystock pastoral farms receipt payments for were surveyed, with 20 being enrolled each following AEOS options: Traditional Hay Meadow (THM), Species-Rich Grassland (SRG) and...
The objective of this systems-scale study was to investigate grazing season timeframes on pasture and milk production processability dairy systems with compact spring-calving cows white clover (Trifolium repens L.) based grassland. Fifty-four primiparous multiparous Holstein-Friesian were used in a one-factor 3 (n = 18) repeated over 2 yr (2008/09 2009/10). were: early spring calving annual fertilizer N input 100 kg·ha−1 applied (ES100N; 2.1 cows·ha−1; February November), without (ES0N; 1.6...
