Effect of Floor Feeding Creep Feed on the Growth Performance and Mortality of Pigs After Weaning

A total of 264 litters (PIC × Duroc (n = 180) or Choice Genetics × Duroc (n = 84)) corresponding to 2,497 nursery pigs were used in a 40-d trial (4-d pre-weaning and 36-d post-weaning) to determine the effect of floor feeding different pellet sizes of creep feed or lactation feed on the growth performance and mortality of pigs after weaning. Treatments were applied in the farrowing house for 4 d prior to weaning and consisted of a control (no creep feed), standard (1/8 in.) creep pellet, large (1/2 in.) creep pellet, or sow lactation feed. For each treatment, approximately 0.50 lb of creep feed per day, equally divided into 2 feedings (AM and PM) was provided on the mat in farrowing stalls. At weaning (approximately d 19 of age), pigs were transported to the nursery facility and randomized to pen within creep feeding treatment group. A total of 96 pens (48 feeders) were used, with one barrow pen and one gilt pen per feeder. Thus, feeder (2 pens) was the experimental unit. There were 26 pigs per pen (52 pigs per feeder) and 12 replications per creep feeding treatment. For creep feeding during lactation, floor feeding different pellet size creep feed or lactation feed had no effects on the percentage of piglets that consumed creep feed (eaters). For the first week post-weaning, pigs fed standard or large pellet creep feed had increased (P \u3c 0.001) ADG compared to pigs fed sow lactation feed or no creep feed. However, this was not driven by an improvement in ADFI. This resulted in an improved (P \u3c 0.001) F/G for pigs fed large pellet creep feed compared to pigs fed sow lactation feed or no creep feed, with pigs fed standard pellet creep feed intermediate. No differences in ADG, ADFI, or F/G were observed throughout the remainder of the nursery period. On a per pig placed basis, pigs fed large pellet creep feed had increased total BW gain (P = 0.024), ADG (P = 0.027), and improved F/G (P = 0.021) compared to pigs fed sow lactation feed, with the other two treatment groups intermediate. This response was a direct reflection of decreased (P = 0.050) total removal rate for pigs fed large pellet creep feed. In summary, floor feeding large pellet creep feed in lactation appears to improve nursery pig growth performance and fallout rates compared to creep feeding sow lactation feed, with standard pellet creep feed or no creep feed having an intermediate effect

Effects of Gruel Feeding and Oral Dextrose on the Survivability of Pigs After Weaning

Two experiments were conducted using 3,087 (Exp. 1) and 988 (Exp. 2) pigs to determine the effect of gruel feeding (Exp. 1) and administering oral dextrose (Exp. 2) on pig survivability after weaning. Upon arrival to the nursery, the smallest 10% of pigs were selected and randomly placed in designated pens with 61 to 108 pigs per pen. Pens of small pigs were assigned to 1 of 2 treatments in a completely randomized design. Treatments consisted of gruel feeding two or four times per day starting 14-d post-placement. At each gruel feeding, approximately 2.5 lb of solid feed was added to a round Rotecna bowl (Rotecna S.A., Agramunt, Spain) located at the front of the pen. Water was added to feed at a decreasing rate over time such that d 0 to 5, 6 to 10, and 11 to 14 the ratio of water to feed was 3:1, 1:1, and 1:3, respectively. In Exp. 2, every other pig removed from general population or pens of small pigs for welfare considerations (lameness, sick, or fallback) received a single 10 mL oral dose of a 50% dextrose solution (Vet One, MWI Animal Health, Boise, ID), as a source of glucose, before being placed in a removal pen. All removed pigs were tagged and weighed, blood glucose measured prior to and 30 min after entering removal pens, and their body temperature recorded. Overall, gruel feeding the small pigs two or four times per day for 14-d post-placement did not influence (P \u3e 0.10) mortality from weaning to the end of gruel feeding (3.78 vs. 4.25%, respectively). Likewise, dextrose administration did not influence (P \u3e 0.10) pig mortality after removal to approximately d 38 after weaning (21.4 vs. 23.4% respectively), even though blood glucose levels increased (P \u3c 0.001) for pigs administered dextrose compared to pigs not administered dextrose (increased by 11.4 vs. 19.1 mg/dL). An interaction was observed for blood glucose and body temperature (P \u3c 0.001). Pigs with a blood glucose less than 70 mg/dL had increased mortality as body temperature at removal increased. In contrast, pigs with a blood glucose between 70 and 120 mg/dL or greater than 120 mg/dL had decreased mortality as body temperature increased. Pigs weighing less than 10 lb at removal had an increased mortality (P \u3c 0.001) compared to pigs weighing greater than 10 lb at removal. In summary, gruel feeding four times per day vs. two times per day or providing removed pigs glucose supplementation did not improve survivability of pigs after weaning. Additionally, removed pigs with low body weight, body temperature below or above the normal range, or high blood glucose had decreased survivability

How warming and steric sea level rise relate to cumulative carbon emissions

Surface warming and steric sea level rise over the global ocean nearly linearly increase with cumulative carbon emissions for an atmosphere-ocean equilibrium, reached many centuries after emissions cease. Surface warming increases with cumulative emissions with a proportionality factor, ΔTsurface:2×CO2/(IB ln 2), ranging from 0.8 to 1.9 K (1000 PgC)−1 for surface air temperature, depending on the climate sensitivity ΔTsurface:2×CO2 and the buffered carbon inventory IB. Steric sea level rise similarly increases with cumulative emissions and depends on the climate sensitivity of the bulk ocean, ranging from 0.4 K to 2.7 K; a factor 0.4 ± 0.2 smaller than that for surface temperature based on diagnostics of two Earth System models. The implied steric sea level rise ranges from 0.7 m to 5 m for a cumulative emission of 5000 PgC, approached perhaps 500 years or more after emissions cease
