Effect of canola meal inclusion as a major protein source in gestation and lactation sow diets with or without enzymes on reproductive performance, milk composition, fecal bacterial profile and nutrient digestibility

Abstract

The objectives of this research were to determine the effects of high inclusion of canola meal (CM) in gestation and lactation diets on lactation performance, milk composition, energy and nutrient digestibility, and gut health in sows and suckling piglet performance. Standardized ileal digestibility (SID) of CP and AA and standardized total tract digestibility (STTD) of P in CM fed to gestating and lactating sows with or without a multi-enzyme complex (MC) was also determined. In Study 1, results showed no differences in sow and litter performance when soybean meal was replaced with increasing levels of CM in lactation diets. However, energy and nutrient digestibilities were reduced with increasing dietary CM inclusion, probably due to increased fiber content. Results indicated that inclusion of up to 30% CM in lactation diet could support satisfactory sow and suckling piglet performance. Results from Study 2 indicated that up to 30% CM could be included in sow diets as a sole protein source from early gestation until weaning without affecting sow and suckling piglet performance, energy and nutrient digestibility, along with an increase in the abundance of beneficial bacteria in the gut. Furthermore, enzyme supplementation improved P digestibility post-farrowing in sows fed CM-containing diets. From

Rapeseed (Brassica napus): Processing, Utilization, and Genetic Improvement

“…It was revealed that the dehulled rapeseed meal could improve the digestibility of phosphorus but did not alter the bodyweight of pigs [185]. Otherwise, Velayudhan et al [186] studied the impact of incorporating rapeseed meal in sows during gestation and lactation and reported that a ratio of 300 g/kg of rapeseed meal could support sows and suckling piglet performances without negative impacts on nutrient digestibility and energy value, and with a positive impact on the sows' gut lactic acid bacteria. In contrast to pigs, sheep could tolerate high-glucosinolate meals and could be fed with rapeseed meals, with no bad effects on the consumption of the meal, the growth performance and weight of sheep, and milk production [187][188][189].…”
