treatments (183.4 mM, P< 0.01), followed by SBM, CONTROL, andCASEIN (163.6, 163, and 157.0 mM) which were higher (P< 0.01) thanthat of UREA and DDGS (142.5 and 121.7 mM). The acetate andpropionate ratio showed three different (P< 0.01) fermentation patterns(SBM and DDGS, 1.56 and 1.27; CASEIN and UREA, 4.53 and3.87; BIURET and CONTROL, 10.94 and 10.31). The SBM and DDGSappeared to alter the dominant species of bacteria present, either byreducing the lactic acid producing species or increasing the lactic acidfermenting species, resulting in an increased pH (SBM and DDGS vsothers, P
Menten (GMM) functions. Two pig specific random effects were includedin each function, one for predicted mature BW and one variableassociated with the age in which maximum ADG was achieved. Alternativeanalyses were completed in which a random effect for a third parameterwas predicted as a linear function of the random effect formature BW. The alternative analyses resulted in improved likelihoodstatistics, substantially smaller SEs for the between pig variance inmature BW and decreased SDs for the predicted age to achieve specifictarget market BWs. The three functions provided similar likelihoodstatistics, residual standard deviations, predicted BWâ€s and predictedmean age (140 days for barrows and 134 days of age for gilts) andmean BW (83 kg for barrows and 73 kg for gilts) at which maximumADG was achieved. The Weibull and Bridges functions predicted thatthree barrows and six gilts had mature BWs of less than 130 kg. TheGMM function allowed for more gradual growth to 50 percent greatermature BWs than the Weibull and Bridges functions. The GMM equationallows for asymmetric sigmoidal growth and in some cases mayprovide a better fit to the BW data of pigs.Key Words: Mixed effects model, Nonlinear growth functions, Piggrowth92 Analysis of the association of number of piglets born alivewith sow level factors and season of farrowing. S. S. Anil*, L. Anil,and J. Deen, University of Minnesota, St. Paul.Data from 152,015 parity records of sows from 14 US farms wereretrieved from PigCHAMP database for the period from 2002 to 2004and analyzed to evaluate the association of number of piglets born alivewith parity, season and year of farrowing, litter attributes (number ofstillborn and mummies) and the number of services required for thatlitter. The farm was included in the analysis as random effect (Procmixed, SAS version 9.1). For analysis, parity was categorized as parity1,2,3,4,5 or >5, number of services as 1 or >1, stillborn and mummies aspresent or absent and season of farrowing as four quarters (Jan-Mar,Apr-Jun, Jul-Sep and Oct-Dec). Parity 1 sows had less (P5 sows. Sows of parities2-5 had higher (P5. Sows with no stillborn or mummies had less (P
