Studies have shown that providing nesting material to farrowing sows reduces the occurrence of redirected nest-building behaviors, improves farrowing traits and maternal behavior, and decreases pre-weaning mortality. However, in some studies, access to nesting material had no effect on farrowing traits and piglet performance. Further, sow response to nest materials are largely variable among studies, mainly influenced by the type and quantity of nesting material provided and farrowing system. Thus, a systematic review and meta-analysis were carried out to evaluate the effects of the provision of nesting materials on farrowing performance, maternal behavior, and piglet performance. A total of 26 articles met the inclusion criteria. Nest-building behavior was enhanced when nesting material was provided. The systematic review indicates that sows supplied with nesting material had reduced pre-farrowing redirected nest-building behavior and reduced postural changes during farrowing. Sows provided with nesting material had increased nursing bouts and had better response to piglet distress call. An increase (P = 0.03) in the number of piglets born alive were observed for sows provided with nesting material. Provision of nesting materials reduced (P < 0.05) piglet birth interval and pre-weaning mortality. The use of straw or lucerne hay as nest materials reduced (P < 0.05) stillbirth rate and pre-weaning mortality. The use of man-made materials (e.g., hessian, jute, or burlap sacks) tended to reduce stillbirth rate (P = 0.06). Provision of nesting materials had no effect (P > 0.05) on weaning weight. The present study strengthened the hypothesis that provision of nesting material to sows prior to farrowing increases sow maternal care traits and piglet performance. • Provide nesting material is essential to increase pre-partal sows-welfare; • Nesting materials reduce stereotypes and postural changes during pre and -farrowing; • Nesting material increase born alive and maternal carefulness after farrowing; • Provide nesting material reduces piglets birth-interval and pre-weaning mortality; • Straw or lucerne reduces stillbirth and man-made materials tend to reduce stillbirth.}, journal={APPLIED ANIMAL BEHAVIOUR SCIENCE}, author={Monteiro, Matheus S. and Muro, Bruno B.

The present study evaluated the effects of altrenogest supplementation in sows during days 6 and 12 of pregnancy on reproductive performance. On day 6 of pregnancy, 301 females were allocated at random to one of the following treatments: CON (Control: non-supplemented females, n = 163) or ALT (females daily supplemented with 20 mg of altrenogest, orally, from day 6 to 12 of pregnancy, n = 138). Ovulation was considered as occurred at 48 h after the first estrus detection to standardize the first day of pregnancy. The supplementation increased the number of total piglets born (ALT: 17.3 ± 0.4; CON: 16.6 ± 0.4), piglets born alive (ALT: 15.6 ± 0.4; CON: 14.8 ± 0.3), and placenta weight (ALT: 4.2 ± 0.1; CON: 3.8 ± 0.1) and decreased the stillbirth rate (ALT: 5.9 ± 0.6; CON: 7.6 ± 0.6) and the number of piglets born weighing less than 800 g (ALT: 6.6 ± 0.6; CON: 8.0 ± 0.6), without impairment on farrowing rate. These results demonstrated that altrenogest supplementation on swine females between days 6 and 12 of pregnancy may be used to improve reproductive performance.}, number={14}, journal={ANIMALS}, author={Donatelli Muro, Bruno Bracco and Rodrigues Oliveira, Ana Clara and Carnevale, Rafaella Fernandes and Leal, Diego Feitosa and Monteiro, Matheus Saliba and Poor, Andre Pegoraro and Pereira, Francisco Alves and Souza, Leury Jesus and Ferreira, Juliana Bonin and Almond, Glen William and et al.}, year={2022}, month={Jul} }

On day12 of the estrus cycle (D0 = first day of standing estrus), 52 gilts were assigned at random to two experimental groups: non-treated gilts (CON, n = 22), serving as controls, and prolonged luteal function group (CYP, n = 30), receiving a single treatment with 10 mg of estradiol cypionate intramuscularly Starting on day 12, blood samples were collected for estradiol and progesterone assays. Estrus detection started on day 17. Gilts from the CON group were inseminated at the onset of natural estrus. On day 28 CYP gilts were treated with PGF2α to induce luteolysis and inseminated at the onset of estrus. Gilts were slaughtered 5 d after the last insemination. A single treatment with estradiol cypionate prolonged luteal function in 90% of treated gilts. The duration of the estrous cycle was longer (p < 0.0001) for CYP gilts compared to CON gilts. CYP gilts showed synchronized estrus 3.96 ± 0.19 d after induction of luteolysis. The conception rate was similar (p = 0.10) for CON and CYP gilts. No difference was observed in the embryo recovery rate (p = 0.18) and total number of embryos per female (p = 0.06). The percentage of unfertilized oocytes, fragmented embryos and viable embryos was similar among females from CON and CYP groups (p > 0.05). The treatment of gilts with a single application of 10 mg of estradiol cypionate on day 12 of the estrous cycle was effective in prolonging luteal function and treatment with PGF2α resulted in synchronized estrus. Additionally, the synchronization protocol had no deleterious effect on fertility and embryonic development.}, number={23}, journal={ANIMALS}, author={Leal, Diego Feitosa and Viana, Carlos Henrique Cabral and Almond, Glen William and Monteiro, Matheus Saliba and Garbossa, Cesar Augusto Pospissil and Carnevale, Rafaella Fernandes and Muro, Bruno Bracco Donatelli and Poor, Andre Pegoraro and Pugliesi, Guilherme and Nichi, Marcilio and et al.}, year={2022}, month={Dec} }

It evinces a strong antioxidant, anti-inflammatory and potential antimicrobial capacity. Selenium biological function is primarily achieved by its presence in selenoproteins as a form of selenocysteine. Selenium deficiency may result in an array of health disorders, affecting many organs and systems; to prevent this, dietary supplementation, mainly in the forms of organic (i.e., selenomethionine and selenocysteine) inorganic (i.e., selenate and selenite) sources is used. In pigs as well as other food animals, dietary selenium supplementation has been used for improving growth performance, immune function, and meat quality. A substantial body of knowledge demonstrates that dietary selenium supplementation is positively associated with overall animal health especially due to its immunomodulatory activity and protection from oxidative damage. Selenium also possesses potential antiviral activity and this is achieved by protecting immune cells against oxidative damage and decreasing viral replication. In this review we endeavor to combine established and novel knowledge on the beneficial effects of dietary selenium supplementation, its antioxidant and immunomodulatory actions, and the putative antimicrobial effect thereof. Furthermore, our review demonstrates the gaps in knowledge pertaining to the use of selenium as an antiviral, underscoring the need for further in vivo and in vitro studies, particularly in pigs.}, number={1}, journal={Journal of Animal Science and Biotechnology}, author={Pecoraro, B.M. and Leal, D.F. and Frias-De-Diego, A. and Browning, M. and Odle, J. and Crisci, E.}, year={2022}, pages={58} }

However, the agents that compose the vaginal microbiota of sows and their changes during infections are not well understood. The first goal of this study was to characterize and compare the vaginal bacterial content of healthy (HE, n = 40) and purulent vulvar discharge sows (VD, n = 270) by a culture-dependent method and MALDI-TOF MS identification. Secondly, we performed 16S rRNA targeted metagenomic approach (n = 72) to compare the vaginal microbiota between these groups. We found a wide variety of bacteria, with Proteobacteria, Firmicutes, and Bacteroidota being the most abundant phyla in both groups, as well as Escherichia-Shigella, Streptococcus, and Bacteroides at the genus level. Most agents identified in the sequencing method also grew in the culture-dependent method, showing the viability of these bacteria. Alpha diversity did not differ between HE and VD sows, regarding sample richness and diversity, but a beta-diversity index showed a different microbiota composition between these groups in two tested herds. ANCOM analysis revealed that Bacteroides pyogenes were more abundant in VD females and can be a marker for this group. Other agents also require attention, such as the Streptococcus dysgalactiae and Staphylococcus hyicus found in remarkably greater relative abundance in VD sows. Network analysis revealed important positive correlations between some potentially pathogenic genera, such as between Escherichia-Shigella, Trueperella, Streptococcus, Corynebacterium, and Prevotella, which did not occur in healthy sows. We conclude that the alteration of the vaginal microbiota between healthy and purulent vulvar discharge sows, although not extreme, could be due to the increase in the relative abundance of specific agents and to associations between potentially pathogenic bacteria.}, number={1}, journal={SCIENTIFIC REPORTS}, author={Poor, Andre P. and Moreno, Luisa Z. and Monteiro, Matheus S. and Matajira, Carlos E.
