Consumers are concerned about the safety of livestock feed stuff with the increasing use of genetically modified organisms. The aim of the present study was to compare the effect of non-GMO sugar-beet pulp (SBP) and canola meal (CM) in the diet with GMO corn-soybean meal basal diets on reproduction performance in gestation-lactation sows and the performance of their litters. A total of 16 lactating sows (Landrace × Yorkshire) with an average parity of 2.4, were randomly allotted to 1 of 2 treatments with 8 sows per treatment starting from the last 4 weeks of gestation to 21 day of lactation. Treatments consisted of genetically modified organism (GMO) basal diet (CON) and GMO basal diet supplemented with Non-GMO beet pulp and canola meal (NO). Sows were individually fed gestation and lactation diets that were formulated to meet or exceed NRC (2012) recommendations for all nutrients. The amount of feed consumed during the lactation periods was recorded and used to calculate the average daily feed intake (ADFI). Number of piglets born and piglets weaned were also recorded to calculate the survival rate. Individual piglet body weight (BW) and litter weights were assessed on days 0, and 26 to calculate average daily gain (ADG). All data were subjected to the GLM procedures of SAS in a randomized complete block design. A probability level of P< 0.05 was considered to be statistically significant.
As a result, in the current study, the inclusion of non-GMO feed ingredients diets showed no comparable effects on the reproductive performance of the sows as that of the basal diet. BW, ADFI, back fat thickness, body condition score, and estrus interval of sows did not differ between treatments. In addition, there was also no significant difference in growth performance of piglets fed NO treatment diets compared with CON diet.
In conclusion, no differences could be observed between CON and NO diets, on neither sow nor litter performance. These results suggest that the utilization of non-GMO sugar-beet pulp and canola meal do not have any adverse effect on the performance of sows and their litters and might be a good alternative for replacing dietary GMO corn-soybean meal.
