Simulation of Sandsage-Bluestem Forage Growth Under Varying Stocking Rates

The effect of stocking rate on forage growth has attracted much research attention in forage science. Findings show that forage growth may be affected by stocking rate, and there is a consensus that high stocking rates lead to soil compaction, which could also in turn affect forage growth because of the changing soil hydrology and increased soil impedance to forage root penetration. In this stu...

Heifer Performance Under Two Stocking Rates on Fourwing Saltbush-Dominated Rangeland

The efficiency of livestock production in shortgrass steppe may be increased by grazing fourwing saltbush (Atriplex canescens [Pursh] Nutt)-dominated rangeland in late fall and/or early spring, but there is a paucity of information concerning stocking rates and animal gains. The objective of this study was to compare the effects of light and moderate stocking rates on weight gains of heifers gr...

Optimization of stocking rates of tiger shrimp under modified improved culture system

With the target of increasing the shrimp (Penaeus monodon) production through farm development and improved grow out management, an experiment was conducted with three different stocking densities viz. 5/m (T1), 7/m (T2) and 9/m (T3). Results of the experiment revealed that, among the water quality parameters, values of dissolved oxygen and transparency were lower in the higher stocking densiti...

Responses of growth rates and growth hormone levels of African catfish (Clarias gariepinus) to stocking density

In order to estimate responses of growth rate and growth hormone of Clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-L tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. On day 30 and 60, the fish growth rates were measured, pituitary growth hormone (GH) mRNA levels and serum GH concentrations were examined by real-time qPCR and ELISA te...
