Os efeitos do pólen apícola (PA) sobre a produtividade de coelhas e láparos e sobre a carcaça e órgãos dos coelhos foram avaliados. Foram utilizadas 20 coelhas Nova Zelândia Branco e seus láparos em delineamento em blocos ao acaso, com quatro tratamentos e cinco blocos, em arranjo fatorial 2 x 2 com dois níveis de suplementação para a coelha e para os láparos após o desmame. A suplementação com PA para as coelhas não influenciou (p > 0,05) a produtividade da coelha e dos láparos durante a lactação, exceto pela taxa de sobrevivência dos láparos (p < 0,003) e a produção total (p < 0,002) e diária (p < 0,001) de leite que aumentou nas coelhas suplementadas. A suplementação para as coelhas e/ou láparos não afetou (p > 0,05) o desempenho dos coelhos do desmame até a idade ao abate, o peso ao abate, características da carcaça, exceto pelos pesos do baço e intestino delgado, maiores em coelhos suplementados. Não foi recomendada a suplementação com PA para coelhas e/ou láparos por não melhorar o desempenho produtivo.

It was evaluated the effects of bee pollen (BP) on the doe and kits productivity and on the carcass and organs of the rabbits. Twenty White New Zealand does and their kits were used in a randomized block design, with four treatments and five blocks, in a factorial arrangement 2 x 2 with two supplementation levels for the doe and for the kits after the weaning. BP supplementation for the does did not influence (p > 0.05) the doe and kit productivity during the lactation, except by the kits survival rate (p < 0.003), the total (p < 0.002) and daily (p < 0.001) milk production that increased in supplemented doe. BP supplementation for the doe and/or kits did not affect (p > 0.05) the rabbit performance from the weaning until the slaughter age, the slaughter weight, carcass characteristics, except by the spleen and small intestine weights, higher in supplemented rabbits. It was not recommended that BP supplementation for does and/or rabbits for not improving the rabbit productive performance.

The effects of liquid vinasse (LV) in the diet for growing rabbits on performance, carcass yield and intestinal morphometry were assessed. Eighty New Zealand white rabbits were used in a randomized block design with five treatments (LV inclusion at 0, 25, 50, 75 and 100 g/kg diet) and four replications. There was no effect of the treatment on final weight, daily weight gain, mortality rate and carcass yield characteristics. The daily intakes of feed, dry matter, crude protein and energy and feed conversion decreased linearly with increase in LV in the diet. Including LV affected the duodenum crypt depth and the ilium villus perimeter and height linearly and affected the duodenum villus perimeter, height and the absorption surfaces and ilium crypt depth and absorption surface quadratically. There was no effect of including LV on jejunum morphometry. Vinasse can be used to feed growing rabbits at up to 87.8 g per kilogram of diet.
