Two trials were conducted aiming to determine the chemical composition, the digestibility of nutrients and energy from dehydrated cashew apple meal, as well as to evaluate the effects generated by including increasing levels (0, 10, 20, 30, 40 and 50%) of this ingredient in growing rabbit feed, on performance, carcass characteristics and economic evaluation. In the digestibility trial, were used 24 rabbits with 55 days of age, distributed in a completely randomized design with two treatments and twelve repetitions, being one reference feed and the other test feed, composed by 70% of the reference feed and 30% DCAM. The coefficients of the dry matter digestibility, crude protein and gross energy of the DCAM were, respectively, 67.79; 30.03 and 48.61%. The digestible dry matter, digestible protein and digestible energy, based on dry matter, were, respectively, 59.55%; 4.76% and 2,119.66 kcal/kg. In the second trial, 120 mixed breed rabbits were used, with an average of 45 days of age and weight 1143 ± 153g. The animals were distributed in a completely randomized design, with six treatments and ten repetitions with two rabbits of the same sex per cage. It was observed that the inclusion of DCAM did not affect (P > 0.05) the feed intake, but reduced (P < 0.05) the feed conversion efficiency, as well as a linear reduction in carcass yield. A quadratic effect on daily weight gain and the ratio meat/bone was observed, with better inclusion level estimated at 25.31 and 24.65%, respectively. The inclusion of DCAM linearly improved economic viability to the level of 50%, however not to harm the weight gain and the ratio meat/bone, it is recommended to include up to 25%.

ResumoDois ensaios foram conduzidos com o objetivo de determinar a composição química, a digestibilidade dos nutrientes e da energia do farelo do pseudofruto do caju desidratado (FPCD), bem como avaliar os efeitos da inclusão de níveis crescentes (0, 10, 20, 30, 40 e 50%) deste ingrediente em rações para coelhos em crescimento, sobre o desempenho, características de carcaça e avaliação econômica. No ensaio de digestibilidade foram utilizados 24 coelhos com 55 dias de idade, distribuídos em um delineamento inteiramente casualizado com dois tratamentos e doze repetições, sendo uma ração referência e outra ração teste, composta por 70% da ração referência e 30% de FPCD. da matéria seca, proteína bruta e energia bruta do FPCD foram, respectivamente, 67,79; 30,03 e 48,61%.

II RESUMO Este trabalho teve por objetivo estudar a influência da fibra oriunda de diferentes fontes (feno de alfafa ABSTRACT The objective of this paper was to study the influence of fiber fractions from different sources (alfalfa hay, linseed bran and corn gluten meal) on performance, digestibility coefficients and meat characteristics of growing rabbits. The animals were distributed into a completely randomized design with three treatments and eight replications, with one reference and two test diets: AH-control diet, with alfalfa hay; LB-total substitution of alfalfa hay by linseed bran and GM-total substitution of alfalfa hay by corn gluten meal. The data were submitted to variance analysis and the averages were compared by Duncan test (P<.05). The largest amount of hemicellulose and the low hydration capacity of the diets AF and GM proportioned greater animals live weight at 89 days of age (2123 and 1934 g, respectively) versus 1797 g of the animals fed with the diet LB and better digestibility coeficients of DM and OM (average of 80.80 for DM and 81.76% for OM, respectively) in relation to diet LB (73.86 and 75.84%, respectively). The diet GM showed a higher digestibility coefficient of NDF (56.59%)

“…The gross margin was obtained by the difference between the gross profit (live animal weight × price kg live animal or carcass weight × price kg slaughtered animal) and the diet cost (weight of diet consumed × price kg diet) (Oliveira & Lui, 2006). The price of one kilogram of live animal was R$5.00, of slaughtered animal, R$12.00, and the diet cost R$0.92 kg.…”

Effect of including liquid vinasse in the diet of rabbits on growth performance

et al. 2013

-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.
