Polyunsaturated (PUFA) long-chain fatty acids (LCFAs) are more potent in eliciting molecular and tissue functional changes in monogastrics than saturated LCFA. From −21 through 10 days relative to parturition dairy cows were fed no supplemental LCFA (control), saturated LCFA (SFAT; mainly 16:0 and 18:0), or fish oil (FISH; high-PUFA). Twenty-seven genes were measured via quantitative RT-PCR in liver tissue on day −14 and day 10. Expression of nuclear receptor co-activators (CARM1, MED1), LCFA metabolism (ACSL1, SCD, ACOX1), and inflammation (IL6, TBK1, IKBKE) genes was lower with SFAT than control on day −14. Expression of SCD, however, was markedly lower with FISH than control or SFAT on both −14 and 10 days. FISH led to further decreases in expression on day 10 of LCFA metabolism (CD36, PLIN2, ACSL1, ACOX1), intracellular energy (UCP2, STK11, PRKAA1), de novo cholesterol synthesis (SREBF2), inflammation (IL6, TBK1, IKBKE), and nuclear receptor signaling genes (PPARD, MED1, NRIP1). No change in expression was observed for PPARA and RXRA. The increase of DGAT2, PLIN2, ACSL1, and ACOX1 on day 10 versus −14 in cows fed SFAT suggested upregulation of both beta-oxidation and lipid droplet (LD) formation. However, liver triacylglycerol concentration was similar among treatments. The hepatokine FGF21 and the gluconeogenic genes PC and PCK1 increased markedly on day 10 versus −14 only in controls. At the levels supplemented, the change in the profile of metabolic genes after parturition in cows fed saturated fat suggested a greater capacity for uptake of fatty acids and intracellular handling without excessive storage of LD.

The diversification of species for bioenergy silviculture in Amazonia will help several local and/or regional industrial segments. Thus, the expansion of knowledge on silvicultural practices of Tachigali vulgaris will support future commercial-scale plantations in Amazonia. This study aimed to evaluate possible differences in diameter, height, and wood volume of T. vulgaris trees grown under different nutritional doses, on two soil texture classes. In addition, we sought to determine the appropriate nutritional dose for the studied types of soil texture aiming at the production of energy wood. The study was conducted in two experimental areas of 1.6 ha each, located in the municipality of Almeirim – Pará, Brazil. Independent analyses were performed in both experimental areas at each age. The experiments were set up in a randomized block design with four blocks. A factorial scheme considering four phosphorus and three potassium doses were adopted, totaling 12 treatments. The diameter at 1.30 m (DBH), equivalent diameter, total height of the trees, and the commercial wood volume with bark per hectare (Vwb ha−1) were evaluated. A significant effect of nutrient doses was reported on DBH at the age of 2 years for the soil with a sandy loam texture. The Vwb ha−1 of the trees at 4, 5, and 6 years old was significantly affected by fertilization in clayey soils. Under the conditions of the present study, the nutritional doses of 0 kg ha−1 of triple superphosphate and 172 kg ha−1 of potassium chloride are recommended for the area with Oxisol of sandy loam texture and 195 kg ha−1 of triple superphosphate and 343 kg ha−1 of potassium chloride are recommended for the area with Oxisol of clayey texture.
