Algas marinhas calcárias na alimentação de fêmeas suínas

Abstract

The present study aimed to evaluate the combination of calcitic limestone (CL), dicalcium phosphate (DP) and calcareous seaweed (CS) in swine females’ diets on productive performance parameters and blood indicators, as well as the effect on productive performance, indicators blood, organ biometrics, intestinal microbiology and gastrointestinal and bone tracts parameters of their litters. A total of 35 swine (DB-DanBred swine genetics) were allocated in a complete randomized block design within two experimental treatments, composed of a control diet (DC) containing CL + DP or DC plus (CS addition in the proportion of 0.4%). The results indicated that there was an increase in litter weight and in the number of piglets weaned for CS addition compared to the control group. In relation to the sows yield differences were observed between the parity orders, where a considerable increase was verified from the second parturition. For milk composition parameters, the treatment with CS showed values higher to the temperature control, density, defatted total solids, protein, lactose and ash. The count of Enterobacteriaceae in the cecum content of animals fed with the CS addition showed a higher value than the control. Therefore, based on the evaluation criteria of the present study, the CS addition as a source of organic calcium in the feeding of swine females can be used as an alternative in the gestation and lactation stages, positively affecting the productive indexes, without harming the biological response of the piglets.
