Effect diets dining and dehydrated waste on kitchen backfat, body weight and yield of sows in gestation and lactation

Abstract

The effect of substituting 0, 10 and 20% commercial concentrate for dehydrated waste room (DCCD) on growth performance and metabolic profiles in lactating sows was assessed. Yorkshire, Hampshire and Landrace 24 commercial sow’s crosses were used.

 Measurement indicators were weight and back fat at calving and weaning bellies, number of piglets born alive and dead; individual weight of the piglet and litter birth, individual weight and litter weaning. Based on the weight and back fat sow there were no significant differences (P < 0.05). With regard to the weight of piglets at birth for the treatment containing 0 and 10% (DCCD), are considered heavy (g) 1846 and 1897, although for the treatment containing 20% (DCCD), are within the average range with a weight of 1709g. For the variable weight of piglets at weaning and litter was no significant difference (p≥0.05) between treatment 1 and 2 while for treatment 3 if a low weight for piglets and for litter weight observed , same as can be observed in weight loss and back fat in sows are statistically different. It is concluded that the quality of the diet is reflected in the production stage of the  sow and depends largely on the content of nutrients. Body weight and backfat (mm) at birth and weaning and the number and weight of piglets, showed variations between treatments. Although for the size and weight of the litter it was lower for the treatment containing (DCCD) than desirable. We must remember that productivity is measured by the number of piglets born alive per litter and the number of weaned piglets, to observe the productivity of sows it is concluded that these parameters obtained are within normal ranges.
