“…Despite the lack of a significant effect of preweaning creep feeding on medication usage and clinical cases postweaning, it is interesting to note that pigs supplemented with LMR + S had a numerically lower incidence of diarrhea (−13%) postweaning compared to the control. This is in agreement with Vodolazska et al (2023) who observed an increase in fecal dry matter early postweaning when liquid feed had been provided to suckling pigs. Supplementing a liquid mixture of milk replacer and starter diet or dry starter diet alone could therefore have familiarized the pig to these indigenous ingredients preweaning, thereby limiting their damaging effect on the intestinal tract early postweaning.…”

“…In the current study, it might be that the period of supplementation with liquid milk replacer was too short (only 3 d) for the LMR + S treatment. Vodolazska et al (2023) supplemented piglets for 10 d and did not observe an increase in weight at weaning. It is likely that liquid milk replacer should be supplemented for a longer period in order to increase weaning weight.…”

“…Suckling piglets have high lactase activity in their small intestine and only a poorly developed capacity to digest starch and other substrates from plant-based ingredients ( Pluske et al, 1997 ). Regarding the lack of response of LMR + S on weaning weight, others have also found that liquid creep feeding did not increase pig weight at weaning ( Martins et al, 2020 ; Byrgesen et al, 2021 ; Vodolazska et al, 2023 ) even when DMd was higher than for dry creep feed (45 g/piglet vs. 25 g/piglet; Byrgesen et al [2021 ]). In the current study, it might be that the period of supplementation with liquid milk replacer was too short (only 3 d) for the LMR + S treatment.…”

The aim of this study was to assess the effect of creep feeding solid starter diet, liquid milk replacer and a liquid mixture of starter diet and milk replacer to suckling pigs on their growth and medication usage up to target slaughter weight (~120 kg). Ninety-one sows and their litters were randomly assigned to one of four post-farrowing treatments at day 107 of gestation; 1) no creep feed provided to weaning at day 28 of age (CONTROL; n=20), 2) dry pelleted starter diet provided as creep feed from day 10 of age to weaning (DPS; n=25), 3) liquid milk replacer provided as creep feed from day 3 of age to weaning (LMR; n=23), and 4) liquid milk replacer provided from day 3 to 6 of age followed by a mixture of liquid milk replacer with an increasing proportion of liquid starter diet to weaning provided as creep feed (LMR+S; n=23). Pig weight and dry matter disappearance (DMd) were recorded during lactation and post-weaning until pigs reached target slaughter weight (~120 kg). At target slaughter weight, carcass weight and quality were recorded. Medication (antibiotic and anti-inflammatory) usage per pig on a litter basis, and number of injections and clinical cases of disease per litter were recorded from birth to slaughter. At day 5 post-weaning, a subset of pigs (n=40) were sacrificed and intestinal samples were collected for histological analysis. Piglets supplemented with DPS had higher DMd of creep feed than those supplemented with LMR or LMR+S (P<0.001). Providing LMR+S to suckling piglets reduced the coefficient of variation (CV) for within-litter piglet weaning weight (P<0.01) compared to DPS and LMR, but CV of LMR+S was similar to that of CONTROL. Providing DPS or LMR to suckling piglets increased piglet weaning weight compared to CONTROL (P<0.001) but pig weight was not significantly different from CONTROL at time-points thereafter. Gain to feed ratio from weaning to day 6 post-weaning was less for LMR pigs compared to all other treatments (P<0.001). Providing DPS or LMR+S to suckling piglets tended to increase post-weaning ileal villus height (P=0.07). Diarrhoea incidence, as well as the number of clinical cases of disease and injections per litter and volume of antibiotic and anti-inflammatory administered per pig pre- and post-weaning were not affected by treatment (P>0.05). In conclusion, supplementing suckling pigs with liquid milk replacer or dry pelleted starter improved growth at weaning, but the benefit did not persist to slaughter.
