0% total Lys and 3.46 Mcal/ kg of ME and were fed from d 107 +/- 1.2 of gestation to weaning. Sows were allotted to dietary treatment based on breed, parity, and the date of d 107 of gestation. Litters were standardized within diet, and pigs were weaned
at an average age of 19 +/- 2.1 d. Sows were fed 3 times daily during lactation. After weaning, sows were fed a common gestation diet and checked twice daily for estrus. Sows were grouped by parity (young sows, <= 3; HSP990 cost mature sows, > 3) for statistical analysis. The data were analyzed as a 2 x 2 factorial arrangement of treatments; the factors were parity (<= 3 or > 3) and SDP (0 or 0.5%). Treatment differences were considered significant at P < 0.10. Mature sows had a greater BW on d 107 of gestation, on d 1 postfarrowing, and at weaning; greater lactation
ADFI; and greater litter BW after cross-fostering, but pig survival to weaning was decreased. Sows fed SDP had a greater gestation interval, litter BW at weaning, and litter ADG, with 1 less lactation day. The effect of SDP addition was dependent PHA-848125 chemical structure on sow parity, as noted by numerous SDP x parity interactions. The addition of SDP increased lactation ADFI in mature sows but decreased ADFI in young sows. Mature sows fed SDP had a greater number of pigs weaned per litter, litter and pig weaning weights, pig survival to weaning, and number of pigs weaned per litter weighing more than 3.6 kg, but the SDP diet had little to no effect on these responses in young sows. Subsequent farrowing data were collected, but no dietary treatment effects (P > 0.10) were observed. The results of this research indicate that SDP increased
productivity of sows in parity 4 or greater.”
“In a previous work, the shape of Arabidopsis seed was described as a cardioid Mocetinostat order modified by a factor of Phi. In addition, J index was defined as the similarity of the seed (in an orthogonal, bi-dimensional image) to a cardioid, thus allowing the quantitative comparison of seed shape in seeds of varieties and mutants at different stages of development. Here, J index is used for modeling changes in seed morphology during the dynamic process of seed imbibition before germination. The analysis was carried out by means of a general linear model with two fixed factors (genotype and time) applied to two Arabidopsis varieties: Columbia and Wassilewskija and two mutants in cellulose synthesis: prc1-1 (CESA6 in Columbia) and kor1-1 (in Wassilewskija). Equations representing the changes in seed form during imbibition are given. The analysis of changes in seed shape by this procedure provides (1) a quantitative method to record changes in seed shape and to compare between genotypes or treatments showing the time points with maximum differences, and (2) the observation of remarkable differences between wild-type seeds and mutants in cellulose biosynthesis, indicating new phenotypic characteristics previously unknown in the latter.
