<p>This study aimed to evaluate the effects of supplementation of oral probiotics on performance, blood biochemical parameters, incidence of diarrhea, and mortality of piglets with high and low birth weight. Seventy-two litters (DB20® × DB30® DanBred Brasil) were randomly distributed in a 2 × 3 factorial arrangement. The treatments consisted of different oral probiotics for piglets in the farrowing stage (12 to 14 piglets/litter): T1—Control group, T2—Probiotic Blend 1, T3—Probiotic Blend 2. The piglets were grouped according to birth weight as low birth weight (LBW) if birth weight (BW) ≤ 1.15&#xa0;kg and high birth weight (HBW) if BW &gt; 1.15&#xa0;kg, totaling six treatments. Performance, glucose levels by glucometer, urea, creatinine, mortality, incidence of diarrhea, and rectal temperature of piglets in the farrowing stage were evaluated. In the nursery stage, we evaluated performance, glucose, urea, creatinine, mortality, and incidence of diarrhea. For mortality, an interaction between BW and treatment was observed.

摘要

This study aimed to evaluate the effects of supplementation of oral probiotics on performance, blood biochemical parameters, incidence of diarrhea, and mortality of piglets with high and low birth weight. Seventy-two litters (DB20® × DB30® DanBred Brasil) were randomly distributed in a 2 × 3 factorial arrangement. The treatments consisted of different oral probiotics for piglets in the farrowing stage (12 to 14 piglets/litter): T1—Control group, T2—Probiotic Blend 1, T3—Probiotic Blend 2. The piglets were grouped according to birth weight as low birth weight (LBW) if birth weight (BW) ≤ 1.15 kg and high birth weight (HBW) if BW > 1.15 kg, totaling six treatments. Performance, glucose levels by glucometer, urea, creatinine, mortality, incidence of diarrhea, and rectal temperature of piglets in the farrowing stage were evaluated. In the nursery stage, we evaluated performance, glucose, urea, creatinine, mortality, and incidence of diarrhea. For mortality, an interaction between BW and treatment was observed. LBW piglets in the Control group had high mortality, whereas LBW piglets in the Blend 1 group showed low mortality. HBW piglets had better daily weight gain (DWG) and daily feed intake (DFI) than LBW piglets at birth, both in the farrowing and nursery stages. The urea and creatinine levels did not change in any of the stages. Glucose levels in the farrowing stage were affected, with the Control group showing lower levels 30 min, 1, and 2 h later glucose level measurement. Thus, the mortality rate may decrease in the farrowing stage in LBW piglets when supplemented with oral probiotics. The performance values showed that HBW piglets are superior to LBW piglets in the farrowing and nursery stages.
