Disease relevance of ADG

  • The average daily weight gain (ADG) was calculated on piglets from birth to Day-45 (ADG(45)) and birth to Day-70 (ADG(70)) [1].
  • Both total body weight gain and ADG increased linearly (P less than .01) as stage of gestation progressed [2].
  • Mean differences in ADG between seropositive and seronegative pigs were 18 g/d (0.04 lb/d) for SIV, 40 g/d (0.09 lb/d) for PRRSV, 38 g/d (0.08 lb/d) for M hyopneumoniae, and 116 g/d (0.26 lb/d) for TGEV [3].
  • Hogs with both anteroventral pneumonia and severe atrophic rhinitis had a 17.6% lower ADG than hogs with neither disease [4].
  • The effect of vaccination was measured by average daily weight gain (ADG), mortality due to edema disease within the 1st 4 wk after weaning, and weight at 3-6 mo of age [5].

Psychiatry related information on ADG

  • Feeding behavior, aggression and social rank were associated with ADG in time-restricted systems but not in ad libitum systems [6].

High impact information on ADG

  • The objective of our cohort study was to identify risk factors in the farrowing section associated with average daily weight gain (ADG) of piglets from birth to weaning [7].
  • Mild reductions in ADG occurred after the Phase I to II dietary change in both weaning groups (P < 0.05), but serum IGF-1 decreased only in the 2W group (P < 0.05) [8].
  • With 20% of the pedigrees in error, the advantages in genetic gain of using BLUP over SP, the method unaffected by errors in pedigree, were 10.5, 3.8 and 14.6% for LS, BF and ADG, respectively [9].
  • No differences existed for postweaning average daily gain (ADG) and probe backfat thickness (PBF); however, progeny sired by HI Hampshire boars were an average of 5.66 units better for the index (I) compared with progeny of LI Hampshire boars [10].
  • The performance traits analyzed were average daily gain (ADG) and backfat adjusted to 105 kg (ABF) [11].

Biological context of ADG

  • It is suggested tentatively that, through enhanced disease resistance, supplementation with ALA of the diets on the farms studied might have a positive influence on ADG [12].

Anatomical context of ADG

  • Correlation between severity of turbinate atrophy and ADG was only partial [13].

Associations of ADG with chemical compounds

  • The results showed pigs treated with 10 mg/kg cadmium significantly decreased average daily gain (ADG) (p<0.05) and increased feed/gain ratio (F/G) (p<0.05) compared to the control [14].

Other interactions of ADG

  • In the Duroc breed one DNA restriction fragment was associated with decreased INDEX (P less than 0.05) and decreased ADG (P less than 0.05) whereas two other fragments were associated with increased BF (P less than 0.05) [15].
  • The methods used to rank boars were: 1) individual record (ADG, ABF), 2) individual record deviated from the contemporary group mean, and 3/4) individual record plus performance of relatives (including/excluding reference boars) using expected progeny differences (EPD) estimated from a reduced animal model (RAM) statistical procedure [11].
  • In the serovar 15 challenged pigs, the only significant difference detected was that the Porcilis APP vaccinated pigs had a better postchallenge ADG than the controls [16].

Analytical, diagnostic and therapeutic context of ADG

  • Pigs fed the 13% protein diet containing added Lys (.17%) or Lys + C had average daily gains (ADG) similar to those fed the 16% protein diet (positive control group) and greater (P less than .05) than those of pigs fed the 13% protein diet (negative controls) [17].
  • Vaccination resulted in a statistically significant increase in ADG in the nursery period but not in the grower-finishing period [5].
