Inclusion of pig feces deep bed compost in feeding of double purpouse crossbred heifer

The objective of this investigation was to evaluate the inclusion of deep bed compost (CP) of rice husk and pig feces in the feeding of double-purpose crossed heifers. For this, 18 heifers fed with CP processed in 12 months were used, obtained from the Hato Porcino Teaching, Research and Linking Unit of the Escuela Superior Politécnica Agropecuaria de Manabí “Manuel Félix López ". An ramdon desing was applied with a bifactorial arrangement [first factor: age (less than 25 months of age and greater than 25 months of age and pregnant with different gestation periods); second factor: levels of deep bed compost (0%, 10% and 20%)], was considered as a covariate to the initial weight. The nutritional composition of the bed compost was determined by a proximal analysis with 5.71% crude protein. No significant differences were found (P> 0.05) in each of the factors and in the interaction of these, the group of animals under 25 months of age had a better weight at the end of the research with 308.48 Kg (± 2.24), while the animals that were fed a diet that included 20% CP had an average weight of 310.18 Kg (± 2.10) at the end of the experiment. It is concluded that the nutritional content found in the deep bed compost did not disadvantage the weight gain and feed conversion, so the diets supplied 20% of porquinaza could be used to improve the productive
