Sow reproductive and progeny growth performance when fed yeast postbiotic: systematic review and meta-analysis.

Previous research suggested that feeding sows with a product containing an inactivated strain specific yeast postbiotic (; Citristim, ADM Animal Nutrition, Quincy, IL) has the potential to support fecundity, and progeny performance at birth, weaning, and after weaning. To summarize these effects, a systematic review followed by a meta-analysis was carried out to determine the effects of feeding sows with PG during gestation and lactation on reproductive the performance of sows and the growth of progeny after weaning. All experiments included were randomized trials reporting side-by-side comparisons of an appropriate control () and the CON with the inclusion of PG.

Feeding a whole-cell inactivated yeast to gestating and lactating sows in a commercial production system.

A total of 606 sows (PIC 1050) and their progeny (PIC 1050 × 280) were used to determine if feeding gestating and lactating sows a proprietary strain of as a whole-cell inactivated yeast product (; CitriStim, ADM Animal Nutrition, Quincy, IL) improves sow and litter performance in a commercial production system. Once confirmed pregnant at d 35 post-breeding pregnancy check, sows were fed a basal gestation control () diet (0.55% SID lysine) or the control diet fortified with 0.

The effects of maternal dietary supplementation of cholecalciferol (vitamin D) and 25(OH)D on sow and progeny performance.

A total of 69 sows (DNA Line 200 × 400) and their progeny were used to determine if feeding a combination of vitamin D and 25(OH)D influences neonatal and sow vitamin D status, muscle fiber morphometrics at birth and weaning, and subsequent growth performance. Within 3 d of breeding, sows were allotted to one of three dietary treatments fortified with 1,500 IU/kg vitamin D (CON), 500 IU/kg vitamin D + 25 μg/kg 25(OH)D (DL), or 1,500 IU/kg vitamin D + 50 μg/kg 25(OH)D (DH). When pigs were sacrificed at birth, there were no treatment effects for all fiber morphometric measures ( > 0.
