ORTIZ-RODRIGUEZ, Ruy et al. Effect of addition of prickly pear (Opuntia ficus-indica) to the diet of lactating sows on the production and quality of milk. Nova scientia [online]. 2017, vol.9, n.18, pp.290-312. ISSN 2007-0705.  https://doi.org/10.21640/ns.v9i18.765.

It was evaluated the effect of adding prickly pears (Opuntia ficus-indica) to lactating sow’s diet on production and quality of milk. Twenty-two hybrid sows (Yorkshire x Landrace x Pietrain) close to farrowing were randomly selected and distributed in two groups (n=11): Control Group (GT) with a balanced concentrated ad libitum diet and Experimental Group (GE) with a 1% of prickly pear day-1 sow-1 (according to pre-farrowing sow’s live weight) plus ad libitum balanced concentrated per 21 days of lactation. The variables evaluated were milk production on 6, 10 and 15d postpartum, as well as lactose, protein and fat percentages on 3, 11 and 17 d of lactation. The data were analized using repited measures and the differences between groups were analized by least squares means. It was not observed differences among groups in milk production (P=0.4904), the milk production peak was observed at day 15 of lactation with 9.1 and 8.7kg for GE and GT, respectively. It was not observed effects of group on milk physical-chemical components: lactose (6.6±0.57), protein (4.5±0.40) and fat (7.9±1.6) (P>0.05). Adding prickly pears to lactating sows did not modify sow’s milk production and physical-chemical components din (protein, lactose and fat) which ensure the appropriated piglet development from birth to weaning (21days).
