Desempenho e características dos dejetos produzidos por cabritos em diferentes idades e alimentados com diferentes proporções entre volumoso e concentrado

This study was conducted to evaluate the performance and characteristics of manure produced by Saanen goats with 90, 120 and 150 days of age and fed three diets, diets 1 = 80 % roughage (R) and 20 % concentrate (C), diets 2 = 60 % R and 40 % C, diets 3 = 40 % R and 60 % C. Were evaluated 24 goats (divided into three groups according to diet ) during the fattening stage, making up the collection of waste at 90, 120 and 150 days of age to quantify the mass of manure produced each day, beyond the content of N, P, K, Ca, Mg, Na, Fe, Cu, Zn and Mn. The animals were weighed weekly and during the collection of waste is evaluated the digestibility of DM, CP and NDF, in addition to the estimate of feed conversion and rate of waste. The best results of feed conversion coefficient of waste and the apparent digestibilities of DM, CP and NDF occurred at the age of 150 days and in animals fed diets containing higher proportions of concentrate. Insofar as the increased age of the animal and level of concentrate in the diets were verified higher production of faeces. All nutrients were also affected, with higher concentrations occurred in the feces of animals at 150 days old and fed with diet 40% R and 60% C.

Valor nutritivo do capim Piatã adubado com diferentes doses de biofertilizante

The aim of this study was to verify the influence of different doses of biofertilizers made from waste produced by cattle and pigs at growing-finishing on nutritive value of Piatã grass. The experiment was carried out at green house using a split plot design with a completely randomized factorial. Plots were divided into eight treatments: four doses of two biofertilizers, and four different periods of subplots cut. Biofertilizers were applied at a single dose, after the cut to standardize the plots, using doses of Nitrogen of 0, 100, 200 and 300 kg ha-1 . The results showed no significant difference among types of biofertilizer and also, the biofertilizer x dose interaction was not significant, making possible to recommend both of biofertilizers, with no risk of plant injure. Contents of neutral detergent fiber, acid detergent fiber, cellulose, hemicellulose and lignin showed negative linear behavior as a function of increasing doses of nitrogen. Contents of crude protein and “in vitro” dry matter digestibility coefficients replied linearly and positively to nitrogen doses. It also observed the effect of cut periods, since plants that were cut in summer showed nutritive value superior to those plants that were cut in autumn.
