| ABSTRACT We investigated the effects of dietary supplementations of yeast (YFA) or non-yeast fermented additives (NYFA) at 5.0 and 10 g kg−1 on the performance parameters and the size of digestive organs of broiler chickens. An isocaloric and isonitrogenous basal diet used as negative control was added with 5.0 or 10.0 g kg−1 of YFA or NYFA. Each of five experimental diets was given to broiler chickens kept in three randomized floor pens, each with 21 birds, from one-day old to 42 days old. Although the feed intake of broiler chickens was not significantly influenced by the diets, there were significant increases in weight gain and improvements in feed conversion ratio and carcass yield in broiler chickens fed the diets supplemented with 5.0 and 10 g kg−1... |

| ABSTRACT This study investigated the effect of transformed Lactobacillys reuteri on intestinal pH and morphology, carcass characteristics, meat quality, and serum biochemical indexes of broiler chickens. A total of 480 broilers were assigned to six treatment groups and fed a phosphorus-adequate diet, a phosphorus-deficient diet, or a phosphorus-deficient diet containing different L. reuteri recombinants. The results showed that transformed L. reuteri decreased the pH in the duodenum and jejunum of chickens at day 21, decreased drip loss and cooking loss of muscles, and improved muscle tenderness of chickens at days 21 and 42, but did not affect carcass characteristics and only slightly decreased abdominal fat. Transformed L. reuteri also significantly... |

| ABSTRACT The effects of processing of pelleted diets and their storage time on the stability of the enzyme complex SSF (solid-state fermentation) were evaluated. Two diets were formulated with the same nutritional composition, differing only in the Schizochytrium sp. levels (0 g kg-1 and 50 g kg-1). The samples were collected during the following processing steps: mixing, then pelleting, and then oven. To evaluate the storage time, the diet ready after drying was considered as day 1. On this day, two samples were obtained, being one kept in a room with ambient temperature of 25 °C and another stored in freezer at -18 °C. At 15, 30, 45, and 60 days, sub-samples were taken. All samples from the processing step and storage time were sent to the laboratory and... |
