Abstract: Few studies have registered signs of mutilation on cetaceans in Brazil, especially from shark attacks. This work describes interactions between cookiecutter sharks Isistius spp. and cetaceans through the analysis of bite records for cetacean carcasses washed ashore on the Bahia coast between 1996 and 2005. Twenty bite records were analyzed in 13 cetacean species, of which the Delphinidae family was the most frequent. After the analysis, Isistius plutodus was identified as the aggressor species on 80% of the records, followed by I. brasiliensis (20%), based on the characteristic shape of the mutilations. The areas most subject to attack in cetaceans were: flanks 40%; head and abdomen 20% each; dorsal 15%; and genital with 5%. The relatively high number of bites on the flanks was probably due to its larger area, which offered greater opportunities to the cookiecutter shark. At least three bite records were related to the possible causes of strandings in delphinids. We recommend further studies on interactions between sharks and cetaceans along the Brazilian coast.

Abstract: the effect of antimicrobial (a) replacement with dehydrated egg (de) and of type of litter (new and recycled) used in the floor covering on pullet performance was evaluated in 1,440 1-d chicks, 720 of each strain (white and brown), allotted to 72 boxes (1 x 1.5 m). recycled litter consisted of sugar cane bagasse containing droppings of broilers chicks with symptoms of coccidiose. the pullets were weighed and assigned to a complete randomized design with a 3 x 2 x 2 (three diets x two litter x two strains) factorial arrangement, in a total of 12 treatments with six replications of 20 pullets. the experimental diets (d) were: d1 = diet with commercial dose of antimicrobial; d2 = diet without antimicrobial; and d3 = diet without antimicrobial + 0.6% of de. de was composed by dehydrated yolk+albumen (55°c for 72 hours) and showed negative result to samonella spp. test. the use of recycled litter decreased pullet performance of two genetic groups, specially the brown ones, that showed lower weights of spleen and bursa of fabricius. this fact suggests better enlargement of lymphoid tissues, and that probably explains the smaller tolerance of white pullets to recycled litter. the antimicrobials minimize negative effect of recycled litter on pullet performance. dehydrated egg is a good alternative to antimicrobials and can improve performance of pullets in the pre-starter on conventional environment.
