Corn production for silage in nitrogen and potassium levels in covering fertilization Sci. Agrar.Paran. / SAP
Neumann, Mikael; Horst, Egon Henrique; Dochwat, André; Leão, Guilherme Fernando Mattos; Carneiro, Murilo klosovski; Mello, Richard Paglia de.
The objective was to evaluate the productivity, morphological and chemical composition, in addition to the economic viability of the corn crop (Zea mays L.) for the production of silage under different levels of nitrogen and potassium fertilization in coverage. Treatments consisted of four coverage levels: T1 (217 kg ha-1 N + 137 kg ha-1 K2O); T2 (295 kg ha-1 N + 163 kg ha-1 K2O); T3 (374 kg ha-1 N + 190 kg ha-1 K2O); and T4 (452 ​​kg ha-1 N + 216 kg ha-1 of K2O). It was found that the fertilization level had no effect (P> 0.05) in the parameters related to plant height, height of the first insertion spike and grain production, however, higher (P <0.05) dry biomass production was obtained with 374 kg ha-1 N + 190 kg ha-1 coverage K2O (32,346 kg...

Prediction of carcass tissue composition of F1 crossbred goats finished on native pasture R. Bras. Zootec.
Silva,Rayana de Medeiros; Pereira Filho,José Morais; Silva,Aderbal Marcos de Azevêdo; Cezar,Marcílio Fontes; Silva,Anderson Luiz Nascimento da; Medeiros,Ariosvaldo Nunes de.
The objective of this study was to estimate tissue composition of the carcass from physical composition of commercial cuts of F1 crossbred goats (Boer with females of non-defined racial standard) finished on native pasture with four levels of supplementation with concentrate (0.0; 0.5; 1.0 and 1.5% of BW in dry matter). It was used 24 non-castrated animals at initial body weight of 15.52 kg and at 120 days of age. The carcass was sectioned in the half, and from the lefthalf carcass, the following cuts were detached: leg, loin, ribs, shoulder and neck, which were dissected in muscle, bone and fat. Carcass weight and yield were predicted from the weight and yield of tissues in the commercial cuts by regression analysis. All the cuts can be used to predict...
