Vinasse in the diet of lactating sows and its effect on litter

The aim of this study was to verify the impact of adding vinasse as an acidifier in sows diet during the lactating period and its effect on litter. A total of 14 agroceres females were used from the first day of lactation until weaning. The vinasse was obtained in a mill near the experimental facility and was stored in sterilized barrels. Animals were distributed in a completely randomized experimental design into two treatments: control liquid diet and liquid diet with the inclusion of vinasse in each feed supply of the day. The diets were supplied four times a day, containing a mixture of ½ L of vinasse and ½ L of water. Feed leftovers were weighted daily. Feed intake was used to evaluate sows performance. The piglets were weighted every week after birth until weaning in order to obtain weight gain. Vinasse inclusion showed an increase (p < 0.05) in feed intake of lactating sows, improving diet palatability. Inclusion of acidifier in the diet did not show (p > 0.05) difference in weight gain of piglets. Vinasse consumption by sows did not influence litter performance. The inclusion of vinasse in the diet of lactating sows is beneficial because increases feed consumption.(AU)

Natural and synthetic pigments in diet of Japanese quails

The objective of this study was to evaluate productive performance and egg quality of Japanese quails (Cortunix japonica) fed with synthetic and natural pigments. The treatments used were: 0.8% paprika extract (Capsicum annuum), 0.8% marigold flower extract, 4% paprika extract and 4% marigold flower extract and 0.045% synthetic pigment (Canthaxanthin) in feed. A total of 240 Japanese quails at 20 weeks of age were distributed in a completely randomized experimental design with five treatments and six replicates, with eight quails per experimental unit (30 experimental units). There was no difference (p > 0.05) for the evaluated parameters, except for yolk color which showed significant difference (p < 0.05) between the treatments used. The inclusion of 0.8% natural pigments in diet of Japanese quails can be used to substitute canthaxathin because it is effective on improving yolk color without affect performance and the quails egg quality.(AU)

The diets were supplied four times a day, containing a mixture of ½ L of vinasse and ½ L of water. Feed leftovers were weighted daily. Feed intake was used to evaluate sows’ performance. The piglets were weighted every week after birth until weaning in order to obtain weight gain. Vinasse inclusion showed an increase (p 0.05) difference in weight gain of piglets. Vinasse consumption by sows did not influence litter performance. The inclusion of vinasse in the diet of lactating sows is beneficial because increases feed consumption.
