Analyses of Feed and Energy Intakes During Lactation for Three Breeds of Sows

Year: 2010

Type: article

Abstract: Daily feed intakes from 993 lactation records from 3 breeds of sows (42 Duroc, 405 Landrace, and 358 Yorkshire sows) were evaluated over a 19-mo period. Mixed models were evaluated for the Bridges, negative exponential, and generalized Michaelis-Menten functions. The generalized Michaelis-Menten function with 2 random effects provided the best fit to both daily feed intake (residual SD = 0.93 kg/d) and ME intake (residual SD = 3.04 Mcal/d). Duroc sows had lower (P 0.10) by stage of lactation (68 early, 77 mid-, and 82 late lactation). The incidence of transient reductions in feed intake was affected (P < 0.05) by season, with incidence rates of 18.8, 16.3, 22.2, and 16.3% for summer, fall, winter, and spring, respectively.
