Pigs can be used in the formation of coffee seedlings; it gradually provides essential nutrients for the development of plants, in addition to promoting the improvement of the substrate and water retention. It was decided, with this work, to evaluate the use of pig compost in the formation of coffee seedlings. The topics studied were: T1 - Witness (absence of organic compound); T2-30% concentration of cattle compost; T3-15% concentration of pig compost; T4 - 30% concentration of pig compost; T5 - 45% concentration of pig compost. The five treatments were arranged in a randomized block design, with five replications. The best treatment for plant height and collection diameter was 45% of pig compost. The best results for the total dry matter were obtained with treatments with 30 and 45% of pig compost. The compost based on pig manure at 30% stood out in comparison to the standard cattle manure at 30%, providing higher levels of M, O, P, Mg and micronutrients (B, Cu, Mn, Zn). The use of 30 or 45% of manure-based compost produces coffee seedlings similar to the 30% of cattle manure composting.
