Weaning Piglets

This study was aimed at evaluating the effects of activated charcoal-herb extractum complex (CHC) on antioxidant status, serum lipid metabolites and its safety supplement in weaning piglets. In experiment 1, a total of 216 piglets (Duroc × Landrace × Large White) weaned at 28 days of age with initial body weight of 8.55 ± 1.18 kg were assigned randomly to six treatment groups. each treatment group had six pens, with six pigs per pen. Pigs were fed a corn-soybean meal-based diet supplemented with 500, 1000, 1500 or 2000 mg kg−1 of CHC over two 14-d periods. Diets supplemented with 0 and 1000 mg kg−1 of montmorillonite (MMT) were set as the negative and positive controls, respectively. In experiment 2, pigs (n = 108) weaned at 28 days of age with initial body weight of 8.58 ± 0.04 kg were randomly assigned to three treatment groups. Each treatment group had six pens, with six pigs per pen. Pigs were fed a corn-soybean meal-based diet supplemented with 0, 1000 or 10,000 mg kg−1 of CHC over two 14-d periods. In experiment 1, on day 14, supplementation with CHC significantly decreased very low-density lipoprotein (VLDL) concentration while they decreased low-density lipoprotein (LDL) concentration on d 28, CHC at 500, 1000 or 1500 mg kg−1 significantly increase high-density lipoprotein (HDL) concentration. Supplementation with 500 or 1000 mg kg−1 CHC reduced serum malondialdehyde (MDA) concentration during the entire experimental period and increased the concentration of serum total superoxide dismutase (T-SOD) on d 14. CHC at 500 or 1000 mg kg−1 significantly reduced the liver MDA concentration and increased liver T-SOD concentration. In experiment 2, increased ADG was obvious during the first 14 days and the whole period in 1000 mg kg−1 supplemented pigs, similarly F: G was lowest in the first 14 days. There was no difference in growth performance, visceral index, haematological and serum biochemical parameters and visceral organs morphology between pigs fed 10,000 mg kg−1 of CHC and control. Together, 500 to 1000 mg kg−1 CHC was confirmed to improve antioxidant status, and serum lipid metabolites in this study and excess supplementation of CHC is safe in weaning piglets.

Abstract We previously found that i.m. injection of GRA, similar to in-feed antibiotics, improves measures of intestinal integrity, nutrient digestibility, and overall growth performance in nursery pigs. In addition, we have demonstrated that the mitigating effects of GRA on the stress of weaning is predominantly done by subsiding the inflammatory response that often accompanies early weaning. The objective of the current study was to explore the most practical methods for delivering GRA to newly weaned pigs. One-hundred and sixty-seven PIC pigs were weaned at 25 ±1.0 days of age (BW 7 ±1.2 kg), and assigned to fourteen treatments (3-4 pigs /pen; 3 pens/treatment). Seven treatments were tested within two sexes (gilts vs. barrows). The treatments were: 1) i.m. injection of GRA (two injections, 0.2 mg/kg BW at -1 and 3 d post-weaning), 2) two levels of in-water GRA (0.8 and 1.6 ppm), 3) in-feed GRA (2.5 and 5.0 ppm), 4) in-feed antibiotic (ANT, 100 ppm tylosin), and 5) control. Dexamethasone was used as GRA. Pigs had free access to in-feed or in-water GRA or ANT during the 1st-week post-weaning. Parameters of growth performance were measured weekly until the end of the nursery phase. A completely randomized design and repeated measurement ANOVA (PROC MIXED) in SAS were used for statistical analyses. In-water, in-feed, and i.m. GRA treatments resulted in growth performance outcomes comparable to that of in-feed ANT. Relative to CON pigs, both ANT and GRA improved ADG and G: F during the nursery phase (P < 0.05). Among the delivery methods tested, 2.5 ppm of in-feed GRA resulted in superior ADG (GRA vs. CON; 0.29 vs. 0.20 kg/d) and G: F (0.63 vs. 0.40 ± 0.05), compared to the control group (P < 0.02). Collectively, these results suggested that in-feed treatment is the best method for delivering GRA to newly weaned pigs.

Hulled Barley

Abstract Barley grain containing more fermentable starch or fiber might be an attractive energy source in weaned pig diets due to benefits on gut health. Barley rapidly-fermentable carbohydrates may serve as prebiotic and slowly-fermentable fiber may decrease diarrhea in weaned pigs. Steam-explosion processing may disrupt the fiber matrix of hulls, increasing slowly-fermentable fiber of barley. To explore, 220 pigs were fed 1 of 5 diets containing 60% cereal grain: 1) low-fermentable hulled barley (LFB); 2) LFB steam-exploded (LFB-E; 1.2 MPa, 120 s); 3) high β-glucan (10% DM) hull-less barley (HFB); 4) high amylose (17% DM) hull-less barley (HFA); or 5) low-fermentable wheat (LFW). Diets were fed starting 1-week post-weaning and formulated to provide 2.4 and 2.3 Mcal net energy (NE)/kg, 5.5 and 5.1 g standardized ileal digestible lysine/Mcal NE for phase 1 (day 1–14) and phase 2 (day 15–35), respectively. For the entire trial (day 1–35), average daily feed intake (ADFI) and average daily gain (ADG) of pigs did not differ among diets. Gain:feed (G:F) did not differ between LFB and LFW diets, but steam-explosion of hulled barley reduced (P < 0.05) G:F. Feces consistency did not differ between LFB and LFW diets, but was better (P < 0.05) for LFB than HFB, HFA and LFB-E diets. For phase 1, G:F of pigs was lower (P < 0.05) for LFB-E diet than LFW diet. For days 22–28, LFB-E diet had greater (P < 0.01) ADFI than HFA diet and tended (P = 0.09) to have a greater ADG than HFB diet. In conclusion, hulled or hull-less barley grain replaced wheat grain without affecting growth performance in weaned pigs. Hulled barley increased feces consistency. Steam-explosion of hulled barley did not increase growth performance of weaned pigs. Barley grain is an attractive energy source for weaned pigs for managing growth and feces consistency.
