Guidelines For Visual Assessment Of Herbage Mass In Pastures, Thomas Griggs, K. Pack

All Current Publications

This fact sheet provides pasture managers with a technique to improve their abilities to budget forage to livestock and determine amounts of forage to reserve for mechanical harvest. They can also use the technique to estimate harvest efficiency and pasture growth rates, forecast future forage supply and plan adjustments in stocking rate to balance forage supply with livestock demand.

Re-Assessment Of Carrying Capacities In The Ashburton River Catchment, Alan L. Payne, A M E Van Vreeswyk, K A. Leighton

Agriculture reports

Potential carrying capacities for land systems in the catchment of the Ashburton River were first estimated in 1983 as a result of a rangeland survey of the area undertaken during 1976, 1977 and 1978. Potential carrying capacity (termed capability capacity in the 1988 report) is a suggested sustainable level of use assuming that all pastures are in good range condition, the entire station is adequately watered for the effective management of livestock and seasonal conditions are average. The Ashburton Land Conservation District Committee had previously requested a re-assessment of carrying capacities for Ashburton stations following the widespread establishment of buffel …

Nutritive Value Of Pastures In Kars District I. Botanical And Nutrient Composition At Different Stages Of Maturity, İsmai̇l Kaya, Ahmet Öncüer, Yücel Ünal, Sedat Yildiz

Turkish Journal of Veterinary & Animal Sciences

The objectives of this study were to examine the botanical composition and determine the nutritive value of pastures in 9 different locations in Kars district with respect to stages of maturity. Samples were collected bi-weekly from 21 May to 30 July 1999. The Gramineae, Leguminoseae and other plant families constituted 64.2, 22.8 and 13.0% of the plant population, respectively. There was a variation in the nutrient composition of samples collected from different locations (P < 0.05). Average dry matter (DM) content was 28.8% and concentrations of organic matter (OM), crude protein (CP), crude fiber (CF), neutral detergent fiber (NDF), nitrogen-free extract (NFE), ether extract (EE) and ash on a DM basis were 90.8, 15.3, 30.0, 57.6, 43.4, 2.0 and 9.2%, respectively. Stage of maturity altered nutrient composition (P < 0.5). Concentrations of OM, NFE and ash did not change, CP linearly decreased, and CF and NDF quadratically increased with advancing maturity. In conclusion, the Gramineae were the predominant flora of pastures in northeastern Turkey. Moreover, mathematical models developed to characterize changes in the nutrient composition of pastures with advancing maturity may help to improve current feeding strategies.

Nutritive Value Of Pastures In Kars District Ii. Degradation Kinetics In The Rumen With Respect To Stages Of Maturity, İsmai̇l Kaya, Sedat Yildiz, Selma Kaya, Ahmet Öncüer

Turkish Journal of Veterinary & Animal Sciences

This study was conducted to determine the ruminal degradation characteristics of nutrients with respect to pasture stage of maturity in Kars district. The nutritional parameters were dry matter (DM), organic matter (OM), crude protein (CP) and crude fiber (CF). Samples were collected from pastures of 9 vicinities of Kars district over a 28-day interval. Three adult Morkaraman rams were fitted with a rumen cannula and samples were incubated in the rumen for 4, 8, 16, 24 and 48 h. Parameters for degradation kinetics included readily degraded fraction, slowly degraded fraction, lag phase and fractional rate of passage. The cumulative disappearance …
