Abstract (sommario):

Fertilisers are usually evaluated by their effects on herbage DM yield and occasionally herbage composition. Rarely are the effects on animal production considered, even though there is evidence for example that increasing the sodium (Na) contents of herbage can increase the milk yield of dairy cows (Chiy and Phillips, 1991), and that dietary sulphur (S) contents in excess of l-2g/kg DM will lead to reduced intake and productivity in ruminants (Raisbeck, 1982). In the UK the use of sulphur fertilizer is widely advocated, since herbage growth is often restricted by deficiency now that industria

Abstract (sommario):

Prevailing weather conditions are one factor that influences herbage growth and quality, and therefore may have a substantial impact on animal production. The objective of the present study was to quantify the associations between weather, herbage quality and mineral concentration, and animal production. Daily weather data and weekly records of herbage quality and mineral concentration, as well as dairy cattle production, were available from a research farm and nearby weather station across the years 1995 to 2001, inclusive. Animal production variables of interest included individual cow milk

Abstract (sommario):

Leymus chinensis (Trin.) Tzvelev grassland is the most widely distributed native steppe vegetation type suitable for haymaking in the semiarid pastoral regions of north-east Asia. The long-term effects of four mowing regimes (mowing once a year, twice a year, once every 2 years and twice every 3 years), and climatic variability on the hay production from L. chinensis grassland were investigated using permanent plots over 27 years. The results showed that (i) the overall cumulative annual herbage production over the 27 years was the highest under ‘mowing once a year’, and ‘mowing twice a year’

Abstract (sommario):

Grasslands in many parts of China are vulnerable to natural disasters which can bring large economic losses to pastoralists. As an effective method to manage the risk, insurance has gradually become an important means used in the management of grassland disasters. Because of insufficient statistical data on annual production of grass herbage, insurance-rate-making has become the core challenge in grassland insurance programs in China.

Abstract (sommario):

The efficiency of wool production – which in the context of this review means largely the production of fine wool in Australia, the largest grower – depends on local conditions and management systems. The main factors, other than genetic, are climatic and edaphic; the proportion of herbage utilized by the sheep; and the proportion of ingested herbage converted into wool.

Species composition and herbage production were determined for different range types used by ungulates in northern British Columbia. In addition, the effect of N fertilization on alpine grasslands was measured. Fire-induced subalpine grasslands produced much more herbage than other range types. Graminoid production, but not forb production, was greater in wet growing seasons. Fertilization of alpine ranges with 17–35 kg N/ha did not increase the herbage production.

Abstract (sommario):

The effects of intensive herbage removal by either grazing or clipping on yield of pinegrass (Calamagrostis rubescens Buckl.) the following year were compared. Both treatments had a similar effect on the subsequent year yield of pinegrass. During the season of treatment, grazing stimulated new tiller production whereas clipping did not. This new tiller production may partially compensate for the fact that grazing removes additional herbage owing to pull-up. In 1 of 2 yr, grazing on about 1 June caused less stand deterioration than grazing near 1 July or 1 Aug.Key words: Pinegrass, herbage remo

Insufficient water availability is one of the most serious environmental stresses for a plant and can be a major limitation to herbage production in many regions.

However, there is little research available concerning the effect on pasture grasses.

Abstract (sommario):

Strategies to increase herbage dry-matter (DM) production are sought for dairy systems. One proposed strategy is tactical spring defoliation with greater pre-grazing herbage mass and higher post-grazing heights. However, there are concerns over the effects of these strategies on herbage quality, DM intake and milk production. Irrigated, diverse pastures in Canterbury, New Zealand, containing perennial ryegrass, white clover, chicory, plantain and lucerne, were managed over two grazing rotations in spring under normal (grazed to 3.5 cm) or lax management (grazed to 5 cm, allowing early ryegrass

Grasslands Maku. An interaction between cutting height and cutting interval was measured for both rhizome number and length. As cutting interval became more frequent, cutting height was more critical, with cutting to 2 cm every 4 weeks producing fewer and shorter rhizomes. Rhizome production increased with increased cutting height and frequent cutting intervals

Pastures fertilised with GB were compared with unfertilised pastures and

Abstract (sommario):

This experiment investigated the effects of defoliation management of Persian clover (Trifolium resupinatum) on herbage production, and in particular, regrowth and losses of production due to senescence. Three heights of defoliation of Persian clover (0, 5, 10 cm above soil level) were superimposed on 3 frequencies of defoliation (4, 6, 12 weeks between harvests until early October; 3, 4.5, 9 weeks subsequently) in a completely randomised pot experiment with 3 replicates. Defoliation management had a large effect on yield of harvested herbage, in agreement with earlier studies with Persian clo

Abstract (sommario):

Twenty percent of forage farmland was devoted to seeded and native pastures in 1991. Common white clover is widely found in native pastures but ladino clover is the main legume recommended. Timothy is the most popular grass for seeded pasture and its yield is increased by N fertilization. More than 30% ladino in pasture decreases the N fertilizer requirement. High fertilization of pasture where beef steers are kept at high stocking rates and moderately fertilized pasture where beef steers are kept at low stocking rates result in similar average daily gains. Excessive steer stocking rates can r

Abstract (sommario):

Sod moisture may be adequate for rapid plant growth for prolonged periods at any time of year In the Charleville district. However, in pastures growing on mulga soils (acid, red earths), the majority of herbage is produced during the warm summer season (October 1 - March 31). Winter rams have to be well above average for herbage grown during these months to exceed 50% of annual production. The predominance of summer-growing (C4) grasses and absence of cool season grasses in the regional flora is the main reason for this pattern. The density of mulga scrub has no effect on seasonal distribution

The herbage yield responses to phosphorus (P) fertilization show large variation and, unlike to cereals, initial soil test P (STP) does not always predict such variation. By using meta-analysis, we reviewed quantitatively 38 Finnish field experiments related to the effects of P fertilization on herbage dry matter (DM) yields in the 1960s – 2000s. The current meta-analysis has several advantages over other type of research aiming to summarize the effect of P fertilization on herbage production. It involves large number of studies, diversity of soils and cultivation zones, and it enables to high

The best grade of native hill sward is the bent-fescue (Agrostis/Festuca) association.

Herbage 7.5 m from a busy dual carriageway has been recorded with 454 mg Pb/kg DM (Motto et al., 1970).The avoidance of lead-contaminated herbage may be the result of low digestibility of the leadcontaminated herbage, so the digestion rate of samples of
