| The objective of this work was to evaluate the reproductive performance of Santa Inês ewes fed a diet supplemented with protected fat. Intervals from lambing to first clinical estrus and to conception, conception rate, prolificacy, live weight and body condition were determined. After lambing, 60 ewes and their offsprings were weighted and randomly assigned to three treatments, based on age, body weight and number of born lambs. Treatments consisted of: control diet, or control diet plus 30 g of protected fat, from lambing to day 25 of post-lambing (Sup25), or to day 60 of post-lambing (Sup60). Out of 60 evaluated ewes, 93.3% returned to estrus, and 74.5% got pregnant, with 73.53% lambing rate and 196.5 days lambing interval. The average periods from... |

| The objective of this work was to evaluate the effect of inclusion of dietary glycerol in replacement to starch on the growth and energy metabolism of Nile tilapia juveniles. The experiment was carried out in a completely randomized design with four treatments (0, 5, 10, and 15% purified glycerol) and six replicates. Pelleted, isonitrogenous, and isocaloric diets were provided for 60 days. Growth performance parameters and muscle glucose and protein concentrations were not affected by dietary glycerol levels. The treatment with 15% glycerol presented higher levels of muscle and liver triglycerides. A quadratic effect of treatments on muscle and liver triglyceride concentrations was observed. The treatment with 0% glycerol presented higher hepatic glucose... |

| Abstract: The objective of this work was to evaluate the effect of copper on the chemical composition of coffee beans and on the quality of the beverage, relating both of them to the Cu leaf contents in coffee (Coffea arabica) plants. Coffee plants were grown in a hydroponic system containing 0.2, 0.4, 0.8, 1.6, and 3.2 μmol L-1 Cu until fruit setting. Coffee bean production was evaluated, and, after the cherries were dried, the following characteristics were determined: leaf Cu content; total titratable acidity; color index; electrical conductivity; leached K; polyphenol oxidase (PPO) activity; concentrations of caffeine, trigonelline, organic acids, total phenols, chlorogenic acids (3-CQA, 4-CQA, and 5-CQA), sucrose, glucose, arabinose, mannose, and... |

| The objective of this work was to evaluate the effects of parboiled rice whole bran (PRWB) inclusion in laying diets for Japanese quails, on their performance, egg quality, and economic viability. A total of 448 17-week-old quails were weighed and distributed in a completely randomized design with seven treatments and eight replicates of eight birds each. A control diet (no PRWB) and six diets, containing 5, 10, 15, 20, 25, and 30% of PRWB, were tested. The increasing levels of PRWB did not affected nutrient digestibility coefficient, dietary energy use, feed intake, egg production, egg weight, egg mass, and the economic viability indices. However, there was a linear decrease in egg shell percentage, specific weight, and yolk color. The inclusion of up to... |

| Abstract: The objective of this work was to characterize banana and plantain genotypes and to identify the most promising for flour production. Sixteen plantain genotypes and four banana cultivars were evaluated for dry matter content and flour yield. The obtained flours were characterized by color (L*, C*, and h*) and by moisture, total and resistant starch, ash, protein, lipid, and fiber contents. A low genetic variability was observed among plantains for the evaluated physicochemical and nutritional characteristics. The Chifre de Vaca, Comprida, Terra Ponta Aparada, Trois Vert, Terrinha, and Terra Maranhão plantains showed the highest dry matter contents and flour yield. The Chifre de Vaca, Comprida, Curare Enano, Mongolo, Trois Vert, and Terra Maranhão... |

| Abstract: The objective of this work was to determine the apparent digestibility coefficient (ADC) of crude protein, crude energy, fat, and dry matter of fish protein hydrolysate (FPH), made of by-products of Nile tilapia (Oreochromis niloticus) and whole sardines (Cetengraulis edentulus), and to evaluate the productive performance and muscle fiber growth of Nile tilapia post-larvae. Two trials were conducted, the first one to determine the digestibility in 120 fingerlings (70.0±2.0 g), and the second one to evaluate the productive performance of 375 post-larvae, with three days of age, which were distributed in 25 aquaria with 30 L of useful volume. Five diets were prepared based on vegetable ingredients, to which fish were included at 0, 2, 4, 6, and 8%... |

| Abstract: The objective of this work was to evaluate the effect of nitrogen fertilization on the mineral composition of leaves, initial growth, and yield of peach (Prunus persica) tree advanced selections grown at a high-planting density. The experiment was carried out between 2012 and 2015 in a randomized complete block design, with a combination of advanced selections of the 'Cascata 1513' and 'Cascata 1067' peach trees and of N fertilization doses (0, 30, 60, and 120 kg ha-1 N). Green weight after pruning, diameter, and increase of trunk diameter, canopy volume, plant height, branch length, number of buds per centimeter of shoot, chlorophyll index, leaf area, rust incidence, average production, number of fruit, and mass of fruit were evaluated. Genotype... |

| The objective of this work was to determine the proper levels of protein and energy in diets of Hoplias lacerdae fingerlings. The dietary crude protein (CP) and gross energy (GE) levels for fingerlings of giant trahira were evaluated in a completely randomized 4x3 factorial design with 35, 39, 43 and 47% CP and 4,100, 4,300 and 4,500 kcal kg-1 of GE, and four replicates. The survival rate was 99.22%, and a linear improvement on the performance parameters was detected after increasing diet crude protein levels. Feed conversion ratio decreased with increasing levels of dietary protein and energy in the diets. A significant interaction between crude protein and gross energy was observed over body protein and mineral matter. Body lipid has increased linearly... |

| Quantile Regression methods have much to offer the investigation of the determinants of dietary intake. Dietary inadequacy or excess occurs at the tails of nutrient and food intakes, and it seems intuitive that intake responses in these areas will differ from elsewhere along the intake distribution. We apply quantile regression to examine the drivers of a key aspect of dietary health, fat density of energy intake in China. The sample of 2612 individuals between the ages of 20 and 45 is derived from the China Health and Nutrition Survey. The following insights emerge: (i) Fat density increases with income, but worryingly the income effect is more pronounced at the upper conditional tail of fat intake (ii) While it is confirmed that an urban location... |

| Feed grains researchers have abundant technical opportunities to select various options for improvement of nutritional characteristics of feed grains. Choosing between those opportunities is a difficult issue for research funding organisations. In this paper, efforts to address the relative economic benefits from the different options for feed grains nutritional improvement are reported. The economic benefits arising from nutritional improvements in various feed grains are examined and compared to the benefits from increasing yields of the feed grains rather than improving their nutritional value. The results of the analysis of these options are presented in an economic surplus framework that enables the major beneficiaries and the relative gains for the... |

| The NAHMS Cattle on Feed Evaluation (COFE) was designed to provide both participants and the industry with information on the nation's feedlot animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid producer sample (3,214 producers) to provide inferences to the nation's feedlot animal population. Included in the study were 13 states that accounted for 85.8 percent of the U.S. cattle-on-feed inventory as of January 1, 1994. NASS telephone interviewers contacted a total of 3,214 producers by telephone or personal interview from August 1 through September 16, 1994 for Part I. Contact for this paper: David Dargatz |
