The objective of the present study were evaluated the performance, quantitative and qualitative characteristics of the carcass in growing rabbits feeding with diets contents different starch levels (22 or 32% on average) by high or low inclusion of corn grain and different fiber sources (alfalfa hay or soybean hulls), in 2×2 factorial design. The experimental diets were pellets and fed ad libitum during 40 days to 40 rabbits weaned at 35 days, housed individually and assigned to a complete randomized […]

The objective of this study was to evaluate the caecal microbial activity and caecotrophy nutritional contribution in rabbits fed diets with differents starch levels (22 or 32% on average) from a high or low inclusion of corn grain and differents fiber sources (alfalfa hay or soybean hulls), in a 2×2 factorial design. In the first experiment, 40 rabbits were individually housed in fattening cages within entirely randomized design, and fed ad libitum from 45 to 85 days of age, when […]

The objective was to evaluate the effect of temporary mother-litter separation on the reproductive performance of lactating does and growth performance of their litters up to 70 days of age. A total of 415 presentations of 157 lactating does assigned to two groups: control, with free nest access, and treated, whose nest access was closed during the 39 hours that preceded mating, were analyzed. From the 415 presentations, 387 resulted in matings and 264 in parturitions. Does of the treated […]

The objective of the present study was to evaluate the nutrients apparent digestibilities in growing rabbits fed diets with different starch levels (22 or 32% on average) by high or low inclusion of corn grain and different fiber sources (alfalfa hay or soybean hulls), in 2×2 factorial outline. The diets were pelleted and supplied to 64 New Zealand White rabbits (16 replicates per treatment), weaned at 34 days, housed individually in metabolism cages and allotted to a complete randomized design. […]

A trial was carried out to verify the effects of the addition of fumaric acid, oligosaccharide mannose (BIO-MOS®), acidifiers (ACID-ALL® ) and oligosaccharide + acidifiers in diets growing rabbits on performance. One hundred NZW rabbits, 50 males and 50 females from 39 to 75 days old, distributed in a randomized experimental design with five treatments, 10 replications and two animals by experimental unit. In the period from 39-50 and 39-75 days of experiment none of these performance characteristics was affected […]

With the objective to evaluate the effect of dietary starch on the productive yield and cecal microbial activity for rabbits in the growing, four experimental diets were formulated to contain increasing corn starch levels (23, 28, 33 and 38 % total starch levels in dry matter basis). A total of 32 White New Zealand rabbits were allotted to finishing cages in a completely randomized block design. The results showed a decreasing linear effect for the feed intake and feed:gain ratio, […]

With the objective to evaluate the effect of dietetic starch on the nutrients apparent digestibility for rabbits in the growing phase, four experimental diets were formulated to contain increasing corn starch levels (23, 28, 33 and 38% total starch levels in dry matter [DM] basis). A total of 20 White New Zealand rabbits were allotted to metabolism cages in a completely randomized design. The results showed a crescent linear effect for the coefficients of apparent digestibility for DM, organic matter […]

Adigestibility assay was carried out to evaluate the nutritional value of hay from the upper third of cassava foliage, variety “Mantiqueira” (Manihot esculenta, Crantz) in sixteen rabbits of New Zeland White breed, eight males and eight females, with 50 days of age. A completely randomized design, with two treatments and eight replicates for treatment, was used. In the test diet, cassava foliage hay replaced 30% DM of the reference diet, containing 19.30% of crude protein, 12.86% of crude fiber and […]

This experiment was conducted to evaluate the effect of the addition of different levels of fumaric acid to diet (.0, .5, 1.0, 1.5, and 2,0%) on the performance of growing rabbits. Fifty rabbits of White New Zealand breed, 25 males and 25 females, from 40 to 80 days of age were alloted to a randomized blocks experimental design with five treatments and ten replicates with one animal per experimental unit. The addition of fumaric acid to the diets did not […]
