| ABSTRACT The objectives of this twelve-week feeding trial were to determine the effects of dietary Saccharomyces cerevisiae and/or zinc oxide on epididymal sperm characteristics, testicular morphometric traits, and growth parameters of bucks. 16 (New Zealand White) bucks 16-wk-old, weighing 2.8kg were randomly allotted to one of 4 treatment groups. Each treatment was replicated four times, with 1 buck per replicate, in a completely randomized design (CRD). Each treatment group was randomly assigned to one of the four commercial experimental diets designated thus: TA = control diet with no additives, TB = 0.12g/kg Saccharomyces cerevisiae, TC = 150mg/kg zinc oxide and TD = 0.12g/kg Saccharomyces cerevisiae +150 mg/kg zinc oxide. Although treatment had no... |

| This study aimed at evaluating the alternative method of zinc oxide and fasting to induce molt in Japanese quails. A total number of 190 48-week-old quails was used. They were at end of laying cycle, and presented low egg production. Quails molted by zinc oxide (Z) were fed a diet containing 25,000 ppm of zinc oxide, and received water ad libitum. Quails treated by fasting (F) received no feed and a day of water restriction. The treatment period was determined by the experimental level of body weight loss (BWL). Birds were submitted to different levels of BWL in order to analyze reproductive system regression (ovary + oviduct), and livability. The following groups were established according to their BWL: Control (untreated quails); F25 (25% BWL by F); F35... |

| The aim of this study was to investigate the presence of Salmonella in common quails submitted to forced molting. A total of 240 quails were divided at 40 weeks of age into four groups: CG (control, quails not submitted to molting); FM (fasting method); WM (fed wheat midds ad libitum); and ZM (zinc oxide method). From each group, 10 cloacal swabs, 10 fecal samples, and 20 egg samples were collected before molting (two weeks) and after molting (two weeks). The microbiological procedures for Salmonella spp. identification were performed in four steps. The agglutination test, using somatic and flagellar antigens, was used to confirm Salmonella-suspected colonies. According to the methodology applied, none of the samples was positive for Salmonella spp. The... |

| ABSTRACT This experiment was carried out to evaluate the effect of different dietary supplementation levels of zinc oxide and of an organic acid blend on broiler performance, carcass traits, and serum parameters. A total of 2400 one-day-old male Ross 308 broiler chicks, with average initial body weight 44.21±0.19g, was distributed according to a completely randomized design in a 2 x 3 factorial arrangement. Six treatments, consisting of diets containing two zinc oxide levels (0 and 0.01% of the diet) and three organic acid blend levels (0, 0.15, and 0.30%) were applied, with eight replicates of 50 birds each. The experimental diets were supplied ad libitum for 42 days. There were significant performance differences among birds fed the different zinc oxide... |
