The objective of this experiment was to determine whether feed form and water supplementation could jointly affect performance of newly weaned piglets. A total of 1319 PIC 359 piglets were randomly allocated to 2 dietary treatments and 2 water treatments in a 2 x 2 factorial design. The diet was either a crumbled pellet (COMPLETE), or a diet formulated using the same crumbled pellet as 70% of the diet together with other ingredients, in meal form, to make an isonitrogenous ration (PARTIAL). No feed grade antibiotics were used and from d 21 all pigs received a common diet. Water treatments were straight water (WATER) or a probiotic nutritional supplement (Furst Water Boost, FWB) that was administered at 16 oz per gallon of stock solution for the first 2 and ½ days post-arrival, metered at 1:128. Pigs were allocated by environment, sex and BW with 33 pigs per pen and 10 replications per treatment. Pens of pigs were weighed and feed disappearance was recorded on d 0, 21, 41, and 54 and used to calculate ADG, ADFI, and G:F. Dead (% mortality) and pulled (% morbidity) pigs were recorded. All data were analyzed using the MIXED procedure of SAS with a randomized complete block design of 2×2 factorial arrangement. Pen served as the experimental unit. There were no diet by water interactions for any measurement. COMPLETE x FWB had the numerically highest ADG and 54-d BW. Overall COMPLETE increased BW, ADG and G:F (P < 0.01) and FWB tended (P < 0.10) to increase BW and increased ADG (P < 0.05) with no effect on G:F. From d 21-41 COMPLETE improved ADG (P = 0.0021) and FWB tended to improve ADG (P = 0.067). In conclusion, effects on piglet performance by diet form and water supplementation were found to be additive, with no interactions. |
