The birds challenged with 24 h before being slaughtered, then, caeca removed subjected counts....

In commercial layer poultry farming, molt induction is an important tool used by egg producers to prolong the production cycle of laying hens. Conventional programs involve total feed withdrawal, which raises questions about animal welfare and increased infection susceptibility. The high incidence paratyphoid salmonellosis infections in farming still health challenge because addition affecting birds, such also cause public problems. this context, experiments were performed with hens at 79 wk...

This study aimed to assess the effects of a Lactobacillus helveticus ATCC 15009-derived postbiotic in mitigating experimental Salmonella Gallinarum infection. For this purpose, sample sp. was inoculated 2 different media, each containing postbiotics (sensitized and nonsensitized). Both inocula had their antagonistic effect over S. tested through spot-on-the-lawn method. It revealed that sensitized higher action potential than nonsensitized one (P < 0.05). Then, 48 day hatch chicks were...

The health of poultry is closely related to how the animals are raised, and gut microbiota plays a key role in fulfillment their productive potential. Lactobacillus spp. bacteria present natural that, when employed as probiotic agents, should several characteristics. This study aims at performing vitro isolation characterization Isolates were obtained from ceca content healthy turkeys through identification morphological, molecular, physiologic They identified Gram staining, catalase...

Contents This study evaluated the reproductive performance of gilts inseminated at three intervals before ovulation (0–12, 13–23, 24–30 h) with sperm doses (SD) stored for 0–48 and 96–120 h. A total 218 PIC Camborough 22 ® were once SD 1.5 × 10 9 sperms. Pregnant (n = 166) slaughtered 30.8 ± 3.7 days after artificial insemination. The number corpora lutea (CL) embryos (TE) was counted.
