چکیده
Abstract Background Nutritional strategies for sows designed to reduce peripartum stress are suggested support postpartum recovery and productivity. Spray-dried plasma (SDP) in sow feed has been reported benefit litter performance. Stressed animals fed diets with SDP have a more efficient immune response supporting animal health. The objectives of the present study using 452 (147 parity 1 sows, 148 2 sows) were determine if 0, 0.5 or 2.5% spray-dried porcine (SDPP) provided from entry maternity through day 5 lactation affects productivity serological oxidation status markers around parturition. Post-weaning parameters including size at next parturition was evaluated, but only during first Results In parturition, total born lower ( P < 0.05) especially allotted diet SDPP.

Effect of fructose consumption during lactation on sow and litter performance and sow plasma constituents.
The effects of dietary consumption of high-fructose corn syrup (HFCS) and dextrose during a 28-d lactation on sow and litter performance and sow plasma constituents were examined in 45 multiparous and 36 primiparous crossbred sows. Isocaloric and isonitrogenous corn-soybean meal diets were formulated to contain either 20% fructose or 20% glucose. Diets were fed on a metabolic BW basis from d 0 ...

Seventy-two primiparous and multiparous sows (36 per dietary treatment) farrowed in 4 groups were used to evaluate the effects of spray-dried plasma protein (SDP) on sow and litter performance during lactation. Dietary lactation treatments consisted of a corn-soybean meal control and a corn-soybean meal diet containing 0.5% SDP. Both diets were formulated to contain 1.0% total Lys and 3.46 Mcal...

The objective of this pilot study was to determine the effect of dietary porcine plasma on circulating insulin-like growth factor 1 (IGF-1) concentrations in gestating sows and characteristics of their litters. Primiparous and multiparous sows were randomly allocated to two treatment groups of sows fed a basal diet or sows fed the basal diet plus 6 g of porcine plasma throughout gestation. On 4...

A novel ultraviolet light irradiation (UV-C, 254 nm) process was designed as an additional safety feature for manufacturing of spray dried porcine plasma (SDPP). In Exp. 1, three 10-L batches of bovine plasma were inoculated with 10(5.2 ± 0.12) tissue culture infectious dose 50 (TCID50) of porcine parvovirus (PPV) per mL of plasma and subjected to UV-C ranging from 0 to 9180 J/L. No viable PPV ...

An experiment was performed to study the effect of litter size before weaning on subsequent body development and composition, feed intake, and reproductive performance of young rabbit does with the objective to improve reproductive performance. Litter size (LS) before weaning (treatment) was 6, 9, or 12 kits. After weaning (30 d), 58 female kits per treatment (in two successive replicates) were...
