Serum concentrations of creatine kinase and of triglycerides during lactation in gilts bred older and in multiparous sows fed ad libitum Arq. Bras. Med. Vet. Zootec.
Nogueira,R.H.G.; Guedes,R.M.C.; Souza,J.C.A..
The aim of this paper was to assess the possible variation in blood concentrations of creatine kinase (CK) and triglycerides in gilts bred older in comparison with multiparous sows. Ten primiparous and ten Camborough multiparous sows from the fourth to seventh parities were used. Breeding age and weight of gilts averaged respectively 231 days and 149.5kg. All females were moved into individual farrowing crates and were managed under the same conditions. Blood samples were collected by puncturing the coccygeal artery on day 7 before expected farrowing, and on days 2, 7, 14, 21 of lactation and 2 days after weaning. No difference in triglycerides and CK serum concentrations between groups were observed. The CK levels were low before farrowing, increased...

Phenotypic correlation of characteristics in the gilt performance test with an average number of live-born piglets through all achieved births, during the reproductive exploitation Arq. Bras. Med. Vet. Zootec.
Radović,I.; Dragin,S.; Katanić,N.; Beuković,D.; Stančić,I.; Mirkov,M.; Horvatovic,M. P..
ABSTRACT Reproductive efficacy of sows dictates the level of profitability of the production itself, and the moment of testing and selection of gilts for breeding (as the parents of a future generation), represents a very important moment. Given the fact that the selection of gilts for breeding is partly based on the weight-gain in the test, in this study we examined the influence of a daily weight-gain of gilts in the test of the manifestation of important reproductive characteristics - the size of the litter of the first and the other parities, as well as the percentage of sows that gave birth in relation to previous breeding process. Data of the 11637 tested gilts that completed the performance test have been used for the test. The studied...

Influence of a spray-dried fat enriched with EPA and DHA on the fatty acid composition of sow milk Ciencia e Investigación Agraria
Grez,Mariola; Gandarillas,Mónica; González,Fernando; Vargas-Bello-Pérez,Einar.
Supplementation with eicosapentaenoic and docosahexaenoic acids (EPA and DHA) through the addition of fish oils to mammal diets during lactation benefits milk production, litter growth and the litter immune system, but there is little evidence supporting the use of oils that have been dried using a spray-drying method designed to cool and crystalize fat particles. The objective of this study was to evaluate the effect of a spray-dried dietary fat enriched with EPA and DHA on the fatty acid composition of sow milk. Fifteen pregnant sows were assigned to three dietary treatments from day 100 of gestation until weaning (day 28). Control sows (CONT) were fed an unsupplemented basal diet, and supplemented sows were fed the basal diet plus 20 g (FOPF20) or 40 g...

Economic Impact of a Ban on the Use of Over-the-Counter Antibiotics in U.S. Swine Rations AgEcon
Hayes, Dermot J.; Jensen, Helen H.; Backstrom, Lennart; Fabiosa, Jacinto F..
Antibiotic drugs are currently used in 90 percent of starter feeds, 75 percent of grower feeds, more than 50 percent of finishing feeds and at least 20 percent of sow feeds (USDA/APHIS). A ban on the use of feed-grade antibiotics would lead to changes in production processes and practices in production of pork, and hence would have an economic impact on the U.S. pork industry and pork market. This study considers the economic effects of a ban in pork production, with no change of regulation on other meats. The analysis uses a set of technical assumptions that are based in large part on a historical analysis of how the Swedish ban influenced the Swedish pork industry to anticipate the potential economic effects. A range of cases is examined. The cases use...

Identification of differentially expressed microRNAs in middle-size ovarian follicles of Meishan and Duroc sows R. Bras. Zootec.
Ma,Li-Peng; Zhao,Zhi-Chao; Li,Tao; Li,Da-Quan; Wang,Xiao-Yan; Song,Cheng-Yi; Qi,Ya-Yin; Huang,Tao.
ABSTRACT This study aimed to investigate the roles of miRNA in the development of ovarian follicles in sows with high ovulation rate. The miRNA expression profiles in middle-size ovarian follicles between Meishan and Duroc sows were characterized by Affymetrix miRNA GeneChip. Seven differentially expressed miRNA were identified. KEGG pathways analyzed the predicted target genes of differentially expressed miRNA by using the DAVID website. The MAPK signaling pathway may affect the process of ovarian follicle development. Our study suggested that miR-21, miR-199a, miR-708, and miR-4334 might play a vital role in the development of ovarian follicles of sow.

Creep feeding improves growth performance of suckling piglets R. Bras. Zootec.
Lee,Sang In; Kim,In Ho.
ABSTRACT The present study evaluated the optimal duration of creep feeding that improves the growth performance and fecal score of piglets and the performance and estrus interval of sows. Sixteen sows (Yorkshire × Landrace) and their litters were used in this 24-day trial. Dietary treatments were: Treatment 1, in which creep feed was not provided; treatment 2, in which creep feed was provided at the 7th day of life (day 7 to weaning); treatment 3, in which creep feed was provided at the 14th day of life (day 14 to weaning); and treatment 4, in which creep feed was provided at the 21st day of life (day 21 to weaning). There was no difference in body weight or loss, backfat thickness or loss, or estrus interval among treatments in the sows. Piglets in...
