Pregnant gilts (n = 126) were assigned randomly to 12 0.4-ha old world-spar bluestem (Bothriochloa ischaemum) pastures in an outdoor swine (Sus scrofa) production system to examine effects of stocking rates (17.5 or 35 gilts/ha; 7 or 14 gilts per pasture) and dietary N on percentage of ground cover, soil nitrate (NO3-) concentration, and reproductive performance. Treatments were arranged factor...

xix). Despite a tendency to interpretative ad hoc-ism, it does bring together the important monographic work (e.g. Bynum, Searle, Stocking, Young) that has been done, and in some instances offers perceptive independent readings of particular figures. One might quarrel with the decision to focus on the natural sciences in isolation from the social (and the failure adequately to appreciate the wa...

The objective of this study was to evaluate the effects of monensin supplementation on animals receiving warm-season grass with limited supplementation. In Exp. 1, treatments were a factorial combination of 2 stocking rates (1.2 and 1.7 animal unit [AU] [500 kg BW]/ha) and supplementation with monensin (200 mg/d) or control (no monensin) distributed in a complete randomized design with 3 replic...

Stocking density and salinity influence on the growth and survival of golden Anabas fry were studied. Experiments were carried out at Hatchery Unit, Institute of Bioscience, Universiti Putra Malaysia, Serdang Selangor, Malaysia. Growth parameters were measured once a month. While survival was monitored daily throughout the experimental period. Water quality such as temperature, dissolved oxygen...

This study was carried out to evaluate the growth response of Nile tilapia; O. niloticus L. to dietary protein levels at two stocking densities. This study was bifactorial designed (3 protein levels × 2 stocking densities). Fish (1.8-2.5 g/fish) was randomly distributed into the aquaria at a rate of 15 or 30 fish/100 L. The temperature was adjusted at 27±1oC. Fish of each density were fed eithe...

In less intensive shrimp culture systems, polychaetes are known to be a major food item of several penaeid species. Under these conditions, very little is known about their population dynamics and the possible interactions with penaeid predation and artificial feeding. This work examined the effects of Penaeus subtilis, predation, stocking density and supplemental feeding on the population dyna...
