ABSTRACT The objective of this study was to describe the growth of freshwater angelfish (Pterophyllum scalare) using the Gompertz model, determining the relative growth and allometric coefficients of body components in relation to body weight and protein weight. Six hundred animals were grown until 233 days of age. Data on chemical composition (water, lipid, protein, and ash) and weight measurements were obtained each 30 days. The Gompertz growth equation was used to analyze chemical allometry and to estimate growth parameters. The relationship between chemical components and body protein was estimated. Protein and body weight increased proportionally, with ash being the earliest nutrient (209.2 days), while lipid deposition occurred later. Linear...

The chemical composition and energy value of guava and tomato wastes for broilers at different ages were determined in this research. The metabolism assays were carried out by using the methodology of total excreta collection to calculate the chemical composition of wastes collected in different months. A total of 270 COBB broiler chicks was used: 150 in the period from 1 to 8 days of age (phase 1) and 120 chicks were used in the period from 10 to 17 days of age (phase 2). The trials were analyzed as completely randomized design with three treatments with five replications of 10 and 8 birds at the respective ages. The treatments consisted of different diets: one reference diet, one with 30% tomato meal and another with 20% guava meal, both partially...

Autores: Bendezu,Hilda Cristina Palma; Sakomura,Nilva Kazue; Hauschild,Luciano; Silva,Edney Pereira da; Dorigam,Juliano Cesar de Paula; Malheiros,Euclides Braga; Fernandes,João Batista Kochenborger.
The objective of this study was to measure the response of Dekalb White laying hens to different intakes of digestible methionine + cystine (met+cys) to optimise their performance. Two hundred eighty-eight Dekalb White laying hens, ranging in age from 33 to 48 weeks, were used in the study. The birds were randomly allocated into eight treatment (levels of met+cys and the control treatment) groups with six replicates of six hens per unit. The experimental diets consisted of seven increasing levels of met+cys (1.37, 2.75, 4.14, 5.51, 6.89, 7.92 and 8.95 g kg−1) and were prepared using a dilution technique. A control treatment was used to confirm that the limiting response was due to met+cys intake. Egg production, feed intake, egg weight, egg mass and feed...

Provedor de dados: 96
Autores: Silva,Edney Pereira da; Rabello,Carlos Bôa-Viagem; Albino,Luiz Fernando Teixeira; Ludke,Jorge Victor; Lima,Michele Bernardino de; Dutra Junior,Wilson Moreira.
This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and that had AMEn and TMEn values obtained by the total excreta collection method from growing broiler chickens and the chemical composition in crude protein (CP), ether extract (EE), mineral matter (MM), gross energy (GE), calcium (Ca) and phosphorus (P). The general equation obtained to estimate AMEn values of poultry offal meal was: AMEn = -2315.69 +...

RESUMO Objetivou-se avaliar o efeito do nível de substituição do gérmen integral de milho (GIM) sobre os valores energéticos obtidos pelos métodos de Matterson e da regressão. Foram utilizadas 120 aves com 45 semanas de idade, da linhagem Embrapa 051. O ensaio foi delineado inteiramente ao acaso, com cinco tratamentos e seis repetições de 4 aves. Os tratamentos foram compostos pela ração referência (RR) e quatro níveis de substituição da RR (10, 20, 30 e 40% pelo GIM). Foi utilizado o método de coleta total de excretas. As variáveis analisadas foram: energia metabolizável aparente (EMA), aparente corrigida para o balanço de nitrogênio (EMAn), tempo (TP) e taxa de passagem (TxP) do GIM. A relação entre as variáveis e os níveis de GIM foi estudada por...

ABSTRACT The purpose of this research was analyze the fit of Gompertz function with or without fixing some of the parameters to describe body growth and major bodily chemical constituents of growing pullets. Weekly, data of body weight and chemical components of body free of feathers and feathers were collected from 1,200 chicks of four laying strains (Hisex Brown, Hisex White, Hy Line Brown and Hy Line White W36) until 18 weeks of age. The variables were subjected to two adjustments fixing, or not, some parameters of Gompertz function. The allometric model parameters were calculated for the chemical components. The lipid and protein composition of the body free of feathers were the components with the biggest change in the last weeks. Moreover, the...

An outstanding feature of poultry production that provides animal protein yield for human feeding is its short production cycle. This characteristic has a linear relationship with waste production. Increasing the inclusion of this residue in diets in the near future is desirable in step with the growth of poultry production since it offers a better environmental and nutritional alternative to current methods. We evaluated the effects on the performance and carcass characteristics of broiler chickens produced by the inclusion of poultry offal meal (POM) in their feed. Treatments consisted of a control diet (corn, Zea mays and soybean, Glycine max) and four diets with inclusion of 30, 60, 90 and 120 g kg-1 of POM. The diets were formulated based on the level...

Provedor de dados: 63
Autores: Dorigam,Juliano Cesar De Paula; Sakomura,Nilva Kazue; Hauschild,Luciano; Silva,Edney Pereira da; Bendezu,Hilda Cristina Palma; Fernandes,João Batista Kochenborger.
Broiler strains available in the poultry industry present different requirements for dietary lysine due to their different growth potentials as a result of their genetic makeup. This study aimed to determine the model parameters for maximum nitrogen retention (NRmaxT), the nitrogen maintenance requirement (NMR) and the efficiency of lysine utilization (bc-1) to reevaluate the lysine (Lys) requirements of male and female broilers. Nitrogen balance trials were performed during three periods (I: 6-21 days, II: 22-37 days, and III: 38-53 days). Seven treatments were used for males and females; the treatments consisted of seven diets with protein levels ranging from 61 to 364 g kg-1 dry matter, with Lys being limiting in the dietary nitrogen (4.91 g of Lys in...

Reading model to estimate optimum economic intakes of amino acids for poultry
Provedor de dados: 65
Autores: Silva,Edney Pereira da; Sakomura,Nilva Kazue; Hauschild,Luciano; Gous,Robert Mervyn.
The use of a linear-plateau procedure to describe the response of an individual in the population has theoretical support, since the maximum potential performance of each individual is genetically determined, and any increment in intake of the limiting nutrient above maintenance will result in a linear response in output until this genetic potential, and hence requirement, is reached. However, because of the distribution of body weights and maximum potential outputs in the population, the mean response of the population is curvilinear, which negates the possibility of defining a 'requirement' for the limiting nutrient, and instead leads to the possibility of defining an optimum economic intake of the nutrient.. The Reading model describes the response of a...

Provedor de dados: 64
Autores: Pereira,Marcelo Maia; Mansano,Cleber Fernando Menegasso; Silva,Edney Pereira da; Stéfani,Marta Verardino De.
Knowledge of the growth of animals is important so that zootechnical activity can be more accurate and sustainable. The objective of this study was to describe the live weight, development of liver tissue and fat body, leg growth, and cumulative food intake of bullfrogs during the fattening phase using nonlinear models. A total of 2,375 bullfrog froglets with an initial weight of 7.03 ± 0.16 g were housed in five fattening pens (12 m²). Ten samplings were performed at intervals of 14 days to obtain the variables studied. These data were used to estimate the parameters of Gompertz and logistic models as a function of time. The estimated values of weight (Wm) and food intake (FIm) at maturity and time when the growth rate is maximum (t*) were closer to...
