Published 2004Staff ViewISSN: 1365-2494Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Current policies for upland pasture management in the UK encourage the integration of environmental objectives with livestock production through extensification of grazing systems. This study tested the hypothesis that a greater sward height in the summer would increase the diversity and abundance of grassland beetles (Coleoptera) as has been demonstrated for insects of indigenous grasslands.The hypothesis was tested with an experiment on an upland sheep pasture in mid-Wales. Experimental treatments received different nitrogen fertilizer inputs (0 or 50 kg ha−1), sheep stocking densities (12 or 9 ewes ha−1) and average sward heights in summer were constrained to 3·5 or 5·5 cm by conserving surplus grass for silage in subplots. Five treatments, replicated in three randomized blocks, combined the two stocking densities and two sward heights without nitrogen fertilizer inputs, with the fifth combining the higher stocking density, shortest sward height and the nitrogen fertilizer input. Beetles were sampled with twelve pitfall traps in each of the fifteen plots from June to September in 1993 and 1995.In years 1 (1993) and 3 (1995) of the experiment, more Coleoptera species occurred in the tall sward (an average of nine species in addition to the forty-one species present in the sward with the conventional sward height). Continuously grazed as opposed to ensiled subplots supported more beetle species but fewer individuals. Species composition of ground (Carabidae) and rove (Staphylinidae) beetles varied between treatments more than the arithmetic differences in species number.The experimental results supported the hypothesis but the benefits of taller swards to species diversity were small in the sown pastures of the study compared with indigenous upland grasslands (c. 33% fewer species). Inheritance effects of drainage, fertilizer and lime inputs, and the different species and management of cultivated pastures, may constrain the conservation benefits of altered pasture management compared with indigenous grasslands.Type of Medium: Electronic ResourceURL: -

Published 2003Staff ViewISSN: 1365-2494Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Abstract The implications for the agricultural productivity of the UK upland sheep systems of reducing nitrogen fertilizer application and lowering stocking rates on perennial ryegrass/white clover swards were studied over 4 years at a site in Wales. The system involved grazing ewes and lambs from birth to weaning on swards maintained at a constant height with surplus herbage made into silage, thereafter ewes and weaned lambs grazed on separate areas until the onset of winter with adjustments to the size of the areas grazed and utilizing surplus pasture areas for silage. Four stocking rates [SR 18, 15, 12 and 9 ewes ha−1 on the total area (grazed and ensiled)] and two levels of annual nitrogen fertilizer application (N 200 and 50 kg ha−1) were studied in five treatments (N200/SR18, N200/SR15, N50/SR15, N50/SR12 and N50/SR9). Average white clover content was negatively correlated with the level of annual nitrogen fertilizer application. White clover content of the swards was maintained over the duration of the experiment with an increasing proportion of clover in the swards receiving 50 kg N ha−1. Control of sward height and the contribution from white clover resulted in similar levels of lamb liveweight gain from birth to weaning in all treatments but fewer lambs reached the slaughter live weight by September at the higher stocking rates and with the lower level of fertilizer application. Three of the five treatments provided adequate winter fodder as silage (N200/SR15, N50/SR12 and N50/SR9). Because of the failure to make adequate winter fodder and the failure of white clover to fully compensate for reduction in nitrogen fertilizer application, it is concluded that nitrogen fertilizer can only be reduced on upland sheep pastures if accompanied by reduced stocking rates.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2494Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Sixty-four samples were used to measure the accuracy of in vitro techniques using rumen fluid-pepsin or pepsin-cellulase for predicting digestibility of grasses grown with different levels of fertilizer calcium(Ca), sulphur(S), phosphorus (P) and nitrogen (N). In each case, fertilizers changed in vivo dry matter digestibility (DMD) and the in vitro techniques accurately predicted the changes in in vivo DMD caused by fertilizer Ca, P and N. The in vitro techniques gave biased estimates of in vivo DMD in studies with fertilizer S. This bias was caused by a decrease in the digestive efficiency of the sheep when fed the unfertilized feed. It was concluded that biased estimates of DMD may be associated with low fertilizer levels and these cannot be eliminated by improving the in vitro techniques and would also apply to estimates of DMD based on chemical analysis of the feed.Type of Medium: Electronic ResourceURL: -

Published 1997Staff ViewISSN: 1365-2494Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Grazed sward surface height was controlled within the range 3·25–4·75 cm during spring and summer in two experiments. In Experiment 1, the effects of stocking two breeds of ewe of similar size but different potential levels of reproductive performance [Brecknock Cheviot (C) and Beulah Speckled Face (B)] at different annual stocking rates of twelve (SR12) and twenty (SR20) per hectare, rates of nitrogen fertilizer of 100 (N100) and 200 (N200) kg N ha−1 annum−1 and different lamb:ewe ratios (C1·2, B1·2 and B1·5) were measured in four treatments (SR20N200C1·2; SR20N200B1·2; SR20N200B1·5; SR12N100C1·2) replicated three times. In each of three years animal performance and yield of silage from areas of pasture surplus to grazing requirements were measured. In Experiment 2, breed B was compared with the Welsh Mule (W) breed, a larger with a higher potential reproductive performance, at two stocking rates, two rates of nitrogen fertilizer and two lamb:ewe ratios set on the basis of results from Experiment 1 (SR18N200B1·5; SR12N100B1·5; SR18N200W1·5; SR18N200W1·7). The treatments were replicated three times. The same terminal sire (Suffolk) was used in both experiments. A primary aim of the experiments was to test the validity of the experimental procedures used for comparing breeds of sheep where nutrition is provided predominately from grazed pastures. In Experiment 1, there was no difference between breeds C and B in the live weights of individual lambs at weaning at the same SR (20), N rate (200) and lamb:ewe ratio (1·2). Breeds C and B produced similar total yields of lamb (633 kg lamb ha−1± 10·5) and silage (193 kg DM ewe−1± 37·7), but breed B had a higher level of potential reproductive performance (1·59 vs. 1·37 lambs ewe−1: P 〈 0·001). The treatments SR20N200B1·5 and SR12N100C1·2 produced, respectively, greater and lesser yields of lamb (725 vs. 384 kg lamb ha−1, P 〈 0·001) and lesser and greater yields of silage (123 vs. 327 kg DM ewe−1, P 〈 0·001). In Experiment 2, the live weight of lambs at weaning from breed W were heavier than from breed B (29·1 vs. 26·2 kg lamb−1, P 〈 0·01) but there was no significant difference in total yield of lamb weaned between breeds W and B at the same SR (18), N rate (200) and lamb:ewe ratio (1·5) (747 kg lamb ha−1± 19·2), or in the yield of silage (66 kg DM ewe−1± 16·4), but breed W had a higher potential reproductive performance (1·85 vs. 1·58 lambs ewe−1, P 〈 0·05). The treatments SR18N200W1·7 and SR12N100B1·5 produced, respectively, greater and lesser yields of lamb (840 vs. 473 kg lamb ha−1, P 〈 0·001) and similar and greater yields of silage (60 vs. 141 kg DM ewe−1, P 〈 0·05). The experimental approach adopted and the management protocols used provided a basis for ranking the performance of the breeds of ewes examined at appropriate levels of annual stocking rate, N-fertilizer input and lamb:ewe ratio.Type of Medium: Electronic ResourceURL: -

ISSN: 1744-313XSource: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyMedicineNotes: Serum IgG (7S) levels differed significantly for chickens from 10 different inbred lines. Within lines differences between B blood groups were statistically significant.The genetic control of serum IgG was further examined using birds from B complex haplotypes marked at the B locus and the Ir-GAT locus. Birds from each of five subgroup haplotypes (B1B1Ir-GAT-Lo and -Hi, B19B19Ir-GAT-Lo and -Hi, and B2B2Ir-GAT intermediate) were tested for levels of serum IgG at 3, 6, 9, and 21 weeks of age. The rate and level of IgG reached in the serum was more than two-fold greater in the GAT-Hi birds than in the GAT-Lo. The Ir region of the B complex exerts some control over the ontogenesis of IgG, though most of the genetic variation seems not to be B complex associated.Type of Medium: Electronic ResourceURL: -
