Differential gestation feeding levels on sow and litter performance, nutrient digestibility and energy homeostasis
… to determine the effects of differential feeding levels during gestation on sow and litter performance, nutrient digestibility and energy homeostasis. In Exp. 1, a total of 160 multiparous sows were allotted to 1 of 4 dietary treatments using a randomized complete block design with BW (BW) …

An investigation of the pathway of nitrogen incorporation into the leaf and root metabolism of Helianthus annuus L
… annuus fed at 50 µg N cm and 300 ~g N cm feeding level was analysed for nitrate, ammonia, and amino compounds. Nitrate accounted for 771to 94% of the total nitrogen transported via the xylem stream. The pathway of nitrate-N assimilation into amino compounds by the leaves and roots of …

The pathway of nitrogen assimilation in Datura stramonium L
… roots of Datura stramonium at different nitrate feeding levels has been investigated using 15N tracer experimentation, enzyme inhibitor studies and enzymological assays. Leaves were fed via their xylem stream with potassium nitrate at -1 -1 two concentration levels: 200 pg. N. ml and 25 JJ8 N. ml …

Growth Potential of Young Black Sea Bass, Centropristis Striata, in Artificial Environments
… a natural diet and a commercial diet at various feeding levels.</p> <p>Growth was affected by type of food, food consumption rate, and fish body weight. For fish having positive weight gain, absolute growth rate (gram/day) increased exponentially as food consumption rate (percent of body weight …

A 14C and 15N study of the effects of ammonium or nitrate nutrition on carbon allocation in Triticum aestivum L. and Zea mays L
… were carried out at 4mM and 12mM nitrogen feeding levels in sand and hydroponic culture respectively. pH of growth media was maintained at 6.0 to 6.5. Measurements made included shoot : root ratios, photosynthetic and root respiratory rates, plant water content, xylem sap analysis, and ¹⁴C …

Nutritional Regulation of Serum Insulin-Like Growth Factor-I Concentration in Cattle
… this objective. In the first study, effects of feeding levels on basal and growth hormone (GH)-stimulated serum concentrations of IGF-I, IGF binding protein-3 (IGFBP-3) and acid-labile subunit (ALS), and their mRNA expression in the liver were determined in beef cows. It was found that increased …
