Resumen: Early gestation may be the best period for sows to recover body reserve losses from previous lactation. The aim of this study was to investigate the effect of different levels of restricted feeding in early gestation on the body status, productive and reproductive performance, and hormonal-metabolic status of primiparous and multiparous sows. A total of 130 sows were randomly assigned to one of three feeding levels: Treatment I, which sows were fed at the level commonly used from day 3 to 28 of gestation (2.5 kg⋅d-1 of a diet with 2.18 Mcal NE⋅kg-1 and 13.72 g CP⋅kg-1), and Treatments II and III, where feed was increased by 25% and 50%, respectively. Sow body status, litter size and weight, early mortalities, reproductive rates, weaning-to-estrus interval, and hormones linked to metabolism were recorded. The highest weight gain, body condition score, and backfat thickness were found in sows fed Treatment III compared to those fed the usual feeding level (Treatment I). No differences among treatment groups were found in litter size or litter weight, although a tendency for more live born piglets and fewer stillbirths was found in sows fed Treatment III. In contrast, litters from sows fed at higher feeding levels had a higher mortality at 72 h compared to those fed at the lowest feeding level (I), which was partly linked to a higher percentage of piglets culled at birth and piglets weighing less than 800 g. There were no differences in conception and farrowing rates, leptin, progesterone, insulin, or cortisol among treatment groups applied in early gestation. In conclusion, increasing the feeding level in sows during early gestation to improve their short-term productive and reproductive performance remains controversial. Further studies are needed to focus on how the restricted feeding level applied could affect the viability and proportion of low-weight piglets.

Título: Effect of Parity on Reproductive Performance and Composition of Sow Colostrum during First 24 h Postpartum
Autor/es principal/es: Segura, Mónica M.; Martínez-Miró, Silvia; López, Miguel J.; Madrid, Josefa; Hernández, Fuensanta
Resumen: The aim of this study is to assess the e ects of parity number on sow reproductive
performance and the chemical and immunological composition of colostrum and immunoglobin
concentrations in the sera of the sows. Colostrum samples were collected at 0, 6 and 24 h after
the births of the first piglets from 56 sows with di erent numbers of parturitions (ranging 1–6).
The piglets born alive to primiparous sows had lower birth weights (p < 0.05) than piglets from
second and fourth parturition sows. The colostrum composition was influenced (p < 0.05) by parity
number: primiparous sows had higher concentrations of dry matter, fat, lactose and non-fat-solids.
No parity-dependent di erences were found concerning total protein amount. Colostrumcomposition
was drastically a ected (p < 0.001) by sampling time—the highest concentrations of dry matter
and protein and lowest concentrations of fat and lactose were found immediately after parturition
(0 h). The study revealed no e ect of parity (p 0.05) on the concentrations of immunoglobulins
in colostrum. The immunoglobulin with the highest level in sow serum at day 110 of gestation
was IgG, while IgA showed the lowest values and greater variability with respect to parity from
an immunological point of view. Regarding the relationship between serum Ig levels at the end
of gestation and colostrum Ig, serum IgG showed a strong correlation with colostrum IgG and
IgM, while colostrum IgG was strongly related with colostrum IgM, but not with IgA. IgA did not
correlate with any other immunoglobulin. The di erent behaviors of the immunoglobins in colostrum
were probably due to IgG coming almost exclusively from the sows’ sera, whereas IgA is mainly
synthetized by the mammary gland

Resumen: Purpose Iron (Fe) deficiency anemia in young children is a global health concern which can be reduced by Fe fortification of foods. Cereal is often one of the first foods given to infants, providing adequate quantities of Fe during weaning. In this work, we have compared iron bioavailability and iron status of four iron sources used to fortify infant cereals, employing piglets as an animal model.
Method The study was conducted on 36 piglets, 30 of them with induced anemia. From day 28 of life, the weaned piglets were fed with four experimental diets (n = 6) each fortified with 120 mg Fe/kg by ferrous sulfate heptahydrate (FSH), electrolytic iron (EI), ferrous fumarate (FF), or micronized dispersible ferric pyrophosphate (MDFP) for another 21 days. In addition, one group of six anemic piglets fed with the basal diet with no iron added (Control−) and a Control+ group of non-anemic piglets (n = 6) were also studied. Blood indicators of iron status were measured after depletion and during the repletion period. The Fe content in organs, hemoglobin regeneration efficiency, and relative bioavailability (RBV) was also determined.
Results The Fe salts adequately treated anemia in the piglets, allowing the animals to recover from the anemic state, although EI was less efficient with regard to replenishing Fe stores giving lower concentrations of plasma ferritin and iron in the spleen, liver, lung, and kidney. In addition, the RBV of EI was 88.27% with respect to the reference iron salt (FSH). Conclusions Ferrous fumarate and MDFP were equally as bioavailable as the reference salt, and were used significantly better than EI in piglets. These results contribute to extend the evidence-based results for recommending the most suitable fortificant for infant cereals.

Resumen: The aim of the present study was to ascertain whether an Allium spp. extract rich in organosulfur compounds, such as propyl thiosulfonate (PTSO), added to the feed of growing-finishing pigs at 5 g/kg enhances growth performance or a ects the fecal microbiome, the levels of short-chain fatty acids, or the antioxidant capacity of the animals. Fifty male growing pigs (large white) of 23.07 2.87 kg average body weight were randomly allotted to two treatments in a 103-day trial. The trial was divided into two periods, an initial growing phase (56-days) and a finishing phase (47-days). Two dietary treatments for each phase (growing and finishing) were used: a control diet (CON) and an experimental diet consisting of the control diet to which 5 g/kg of Allium spp. extract was added to substitute sepiolite (GAR). Throughout the study, body weight, average daily gain (kg/day, ADG), feed intake (kg/day), and feed conversion ratio (kg/kg) were measured, while the backfat thickness and muscle depth were determined at the end of the study. Besides, feces samples were taken for bacterial counts by means of real-time PCR and short- chain fatty acid (SCFA) profile determination, and the antioxidant capacity was assessed in serum and saliva. In the animals receiving Allium spp. extract (5 g/kg) in the feed, ADG increased (p < 0.05) throughout the trial, Salmonella spp. and Clostridium spp. counts in feces had decreased (p < 0.05) when measured on day 56, and, by day 103, Salmonella spp., Clostridium spp., and Enterobacteriaceae counts had decreased (p < 0.05) and Lactobacillus spp. counts had increased (p < 0.01) in feces. Regarding the SCFA profile in feces and antioxidant capacity measured in serum and saliva, supplementation with Allium spp. extract significantly increased the levels of propionic, isobutyric, and isovaleric acids and the percentage of total branched fatty acids, while the c2/c3 and (c2 + c4)/c3 ratios were lower (p < 0.05) in feces; the Trolox equivalent antioxidant capacity and the cupric reducing antioxidant capacity levels in serum were significantly higher in the same pigs on day 103 than on day 0. Consequently, based on the current results, Allium spp. extract rich in organosulfur compounds, added to the diet at 5 g/kg,had a beneficial e ect on the microbiota and would seem to be a possible alternative for increasing the growth performance of growing-finishing pigs. However, further studies on the e ects of Allium spp. supplementation on carcass quality are necessary.
