This study examined whether nutritional support can improve the growth rate of piglets identified as having poor growth potential. Cross-fostering (CF) and CF plus a milk supplement (CF + MS) were used to attempt to improve the growth performance of pigs. Blood was collected at d1 post-parturition for measurement of plasma AGP for all pigs in 28 litters contributing to the experiment. Piglets with the highest plasma AGP level were weight and sex matched to a littermate with a low plasma AGP concentration and four pairs of these weight and sex matched pigs were grouped into four foster litters per treatment (control, CF, CF + MS). The control group was assembled by pairing littermates remaining in donor litters. Pigs stayed on treatment until weaning at 21 days of age. At 35 days of age, dual energy X-ray absorptiometry (DXA) was performed on CF and CF + MS pigs to evaluate carcass composition. Control pairs differed in weaning weight, with pigs with higher plasma AGP at 1 day of age having smaller weaning weights than their littermates of similar birth weight (P < 0.05). However, CF eliminated the difference in weaning weight between the slow growing pigs and their birth weight matched littermates. CF + MS produced a similar effect as CF (P > 0.05). At 35 days of age, body weights were still similar between CF littermates and between CF + MS littermates (P > 0.05). DXA analysis demonstrated that body composition was similar between CF or CF + MS treated pigs and their littermates. These data demonstrate that CF can be used to correct the growth impairment in pigs predicted using plasma AGP as the marker. CF + MS can do the same, but at greater expense.展开更多

The radionuclides were determined by Gross alpha, beta and gamma spectrometry Proportional counter + NaI(Tl) detector type(XLB5) and gamma-ray spectroscopy with (HPGe) techniques. The activity concentration of 40K ranged from 124.1 Bq/kg in (Crust sample) to 88.3 Bq/kg in (Chamomile sample), for gross alpha ranged from (N.D.) in (Flax sample) to 0.4 cpm in (Anise sample), while for beta ranged from 5.7 cpm in (Flax sample) to 25.6 cpm in (Latency sample) and for gamma ranged from 0.6 cpm in (Thyme sample) to 5.10 cpm in (Coriander and Flax samples).展开更多

Both hexadecapole deformation and deformed surface diffuseness can affect barrier characteristics and enhance fusion cross-section. Good agreement between experimental data and theoretical calculations with quadrupole and hexadecapole deformation and deformed surface diffuseness were observed for the 4^He＋^154^Sm,235^U,237^Np reactions.展开更多
