Evaluation and characterization of triticale silage (x. Triticosecale wittmack) to replace Sorghum bicolor (L.) Moench (S. vulgare Pers.) silage as feed for beef cattle

Semina Ciências Agrárias (2019)

Éderson Luis Henz Leandro das Dôres Ferreira da Silva Valter Harry Bumbieris Fernando Luiz Massaro Ediane Zanin

The objective of this study was to evaluate the nutritional quality of silages containing 0, 25, 50, 75 and 100% triticale replacing sorghum silage feed for beef cattle. It was carried out fractionation of carbohydrates and proteins, and the parameters of ruminal degradation kinetics estimated by semiautomatic in vitro method of cumulative gas production of the silages. The experimental design completely randomized with five treatments and four replicates. Sorghum silage has less non-fibrous carbohydrates, and its substitution may explain the linear increase in the composition of fractions A and B1. In general, the proportions of fractions "A" and "B1 + B2" demonstrated that as sorghum replaced by triticale, the abundance of high availability proteins increased, as did the abundance of rapidly degradable proteins in the rumen. The final volume of gases produced by the fermentation of non-fibrous carbohydrates presented a negative linear relationship with increased triticale silage (P = 0.0001), while the degradation rates presented a positive linear relationship (P = 0.0001). Thus, there was rapid release of energy and nitrogen, which may meet the needs of microorganisms. Therefore, triticale silage can be substituted for sorghum silage in cattle feed as an excellent source of protein and energy without altering nutritional parameters.

<b>Nutritional composition of pre-dried silage of different winter cereals

Acta Scientiarum Animal Sciences (2018)

Egon Henrique Horst Mikael Neumann Juliana Mareze Guilherme Fernando Mattos Leão Valter Harry Bumbieris

This study aimed to assess the chemical composition of the forage and pre-dried silage from twelve winter cereals harvested at pre-flowering. We used black oat (Avena strigosa) cv. EMB 139 and cv. IAPAR 61; white oat (Avena sativa) cv. IPR and 126 hp. URS Taura; barley (Hordeum vulgare) cv. BRS Brau and cv. BRS Cauê; wheat (Triticum aestivum) cv. BRS Umbu and cv. BRS Tarumã; rye (Secale cereale) cv. Temprano and cv. BRS Serrano; and triticale (X. Triticosecale) cv. IPR and 111 hp. BRS Saturno. Plants were harvested at pre-flowering, when they were pre-dried and ensiled. The analysis of variance evidenced nutritional differences between species and cultivars. Triticale cv. IPR 111 showed notorious chemical characteristics in relation to the other treatments, highest protein content (113.7 g kg-1) and lower content of NDF and ADF (657.9 and 380.9 g kg-1, respectively). Among the pre-dried silages, barley cv. BRS Cauê had the highest level of NDT (614.7 g kg-1). Triticale cv. IPR 111 was shown as a high-quality nutritional food as forage and kept these characteristics after conservation. On the other hand, the pre-dried silage of barley cv. BRS Cauê showed the highest potential for nutrient degradability.

Degradabilidade ruminal e fracionamento de carboidratos e proteínas em silagens de triticale em cultivo singular ou em misturas com aveia e/ou leguminosas

Semina Ciências Agrárias (2011)

Valter Harry Bumbieris Clóves Cabreira Jobim Jean-Claude Émile Robson Marcelo Rossi Moysés Calixto

It was aimed to evaluate the ruminal degradability, and the fractioning of carbohydrates, as well as of the nitrogen fractions of triticale silages in singular culture or in mixtures with oats and/or legumes. The treatments had been: triticale silage (X. Triticosecale Wittimack) (ST); triticale silage + forage pea (Pisum arvense) (STE); triticale silage + oats (Avena strigosa Scheb) + forage pea + vetch (Vicia sativa) (STAE). Three castrated bovine Prim’Holstein males had been used, with average live weight of 300 kg, having ruminal cannulas. The incubation times had duration of 0, 6, 12, 24, 48, 72 and 96 hours. Fractions, a, c and ED of the DM of STAE silage was higher (30,33; 0,026 and 45,45%) than others silages. Fraction b of the DM of ST silage was higher (58,45%) than STE silages (45,36%) and STAE (44,37%). In CP the ST silage presented higher fraction (72.12%). For the potentially degradability fraction (b) of CP it was not observed difference among treatments. The degradation rate (c) of the CP was higher for STE silage (0.063%) than ST ensilage (0,012%), however this was similar to the STAE (0,045%). ED of CP was better for STE silage (77,71%). ST silage presented fraction a and b for NDF highest (8,62 and 81,99%) than others silages. The degradation rate (c) of NDF was higher for STAE (0,027%). ED for NDF did not present difference among treatments. ST silage presented the best values for the total carbohydrates (83,97%) than STE (79,87%) and STAE silages (76,77%). STE and STAE silages presented better DM degradability and suggest to be a potential source of non degradable protein in the rumen. The exclusive triticale silage revealed superior with regard to the degradability of fiber fraction, also presenting higher amount of total carbohydrates potentially degraded.

Introduction of sugar cane bagasse pellets in diets devoid of long fiber for feedlots finished steers

Semina Ciências Agrárias (2016)

Mikael Neumann Robson Kyoshi Ueno Letícia Farias Perussolo Luiz Fernando Menegazzo Gheller Mateus Poczynek

The use of diets without roughage in beef feedlot has become common in recent years due to practicality, feasibility and availability of inputs. However, the introduction of roughage that does not harm the operation of the feeding management can bring health benefits to animals and economic gain. This study aimed to evaluate the productive and economic performance of steers finished in feedlot, fed three levels of sugar cane bagasse pellets (SBP) in diets without long-fiber. The treatments consisted of 0%, 7% and 14% of SBP in a mixture of concentrate, comprising 80% whole corn grain plus 20% of a protein core. The experimental design was completely randomized with four replications. The diet with 0% of SBP promoted lower dry matter intake and weight gain. Feed conversion was similar between treatments, with an average of 6.21 kg-1. The lower dry matter digestibility was found in the diet with 14% of SBP. The introduction of SBP did not change the rumination, averaging 1.9 hours day-1. Animals fed 7% of SBP showed higher fat thickness. Due to the numerical differences between treatments for feed conversion in housing and daily cost of food, the profit margin was maximal in the diet with 0% of SBP, with values of R$ 338.1; R$ 311.6 and R$ 305,1 per animal, respectively 0%, 7% and 14% of SBP. The introduction of SBP promoted improvements in production performance, but did not improve the economic results of steers finished in feedlot.

Efectos del suero ácido sobre la calidad química fermentativa y la estabilidad aeróbica del ensilado de grano de maíz rehidratado

Revista Mexicana de Ciencias Pecuarias (2022)

Ediane Zanin Egon Henrique Horst Caio Abércio da Silva Valter Harry Bumbieris

The objective was to evaluate the fermentative, chemical characteristics and aerobic stability of corn grain silages rehydrated with whey fluid (WF) or whey powder (WP) and water, with or without the addition of inoculant (I). The corn grain was ground and hydrated adding water without chlorine and/or whey to reach 35 % humidity and stored in silos of 4.36 kg. After 45 d of fermentation, samples of the silages were submitted to chemical-fermentative analyses in opening of silos and 240 h of exposure to air. The aerobic stability of the silages was evaluating during 240 h has considered to the loss when the temperature of the ensiled mass exceeded the ambient temperature by 2 °C. A reduction in the acid detergent fiber (ADF) and lignin content of the silages was observed with the use of WF and WP. The levels of ammoniacal nitrogen (NH3-N) were the lowest for WF and WP (0.7 and 0.9 g/kg TN) and pH was 4.31 for WF after 240 h of aerobic exposure. The use of inoculants provided higher levels of Ash, ether extract (EE), and low buffering capacity (BC), in addition to reductions in ADF levels. The inoculated silages showed higher levels of NH3-N and pH after 240 h. The silage of corn grains rehydrated with WF provided ideal pH values, low NH3-N content, reduced levels of ADF and lignin, and improved aerobic stability. In addition to being a sustainable alternative, the use of fluid whey to rehydrate corn grains adds nutritional value and improves silage fermentation.

Effects of dietary energy level on the performance and carcass characteristics of lambs

Semina Ciências Agrárias (2020)

Walter Piola Filipe Alexandre Boscaro de Castro Valter Harry Bumbieris Leandro das Dôres Ferreira da Silva Carolina Amália Souza Dantas Muniz

The objective of this study was to evaluate the influence of ration energy levels on the performance and carcass characteristics of confined lambs. Four energy levels were evaluated: 2.00; 2.28; 2.54, and 2.80 Mcal of ME kg-1DM, with the last content being recommended by the National Research Council [NRC] (2007) for daily weight gains of 300 g. Twenty-four crossbred Ile de France ram lambs (six per treatment) at 240.0 ± 9.6 days of age and 26.6 ± 3.8 kg body weight, fed with isoprotein diets (158 g kg-1, CP) were used. The confinement lasted 57 days. Final body weight, cold carcass weight, and cold carcass yield were linearly and positively influenced by diet energy content. Food intake, average daily weight gain, and feed conversion were quadratically influenced by energy level, where the highest averages were observed under diets containing between 2.54 and 2.80 Mcal. In percentage terms, the main carcass cuts (leg and shoulder) were not influenced by diet energy level. In terms of the shoulder tissue composition, it was observed that bone content decreased linearly, fat content increased quadratically, and muscle content was not affected by the energy content of the diet. It was concluded that diets with higher energy densities lead to the production of heavier carcasses with higher yields, as well as increased weight gains. Optimal diets should therefore contain between 2.54 and 2.80 Mcal of ME kg-1DM.

Enthalpy as a thermal comfort index in broiler poultry production

Revista Brasileira de Engenharia Agrícola e Ambiental (2023)

César A. Pecoraro João Carlos Gonçalves Emanuele H. Nunes Valter Harry Bumbieris João Tavares Filho

ABSTRACT Enthalpy is currently suggested as a suitable index for assessing the internal environment of poultry production, primarily dependents on air temperature and relative air humidity. This study aimed to analyze enthalpy in bird production in Londrina, located in the northern region of Paraná, Brazil, and to model the comfort enthalpy required for enhanced production efficiency. Data from 1961 to 2021 from the Instituto Nacional de Meteorologia (INMET), Brasília, Federal District, Brazil, were utilized to compare the thermal comfort conditions and critical limits set for the birds. The meteorological data from this period were scrutinized to understand their variations and interrelationship through a descriptive study and correlation analysis of different parameters. The research findings, based on the enthalpy indices derive historical averages, suggest that heating is crucial for birds during the first and second weeks of housing, during the winter, given the location’s low temperatures. For birds housed during the third to sixth weeks of age, the enthalpy indices indicated the necessity of cooling systems.

Rondineli Pavezzi Barbero Marco Aurélio Alves de Freitas Barbosa Letícia Maria de Castro Edson Luís de Azambuja Ribeiro Ivone Yurika Mizubuti

Foram avaliados os efeitos economicos de quatro alturas de pastejo (20; 40; 60 e 80 cm) do capim Tanzânia para bovinos de corte. A area total foi de 12 hectares divididos em piquetes de um hectare, com tres repeticoes. Foram utilizados tres bovinos, machos, Nelore por piquete, mais animais adicionais conforme necessidade de ajuste para as alturas pretendidas. A reducao da altura do pasto permitiu maior taxa de lotacao, onde, mesmo com reducao no desempenho individual, houve maior producao por area. A taxa de juros atribuida sobre o capital do imovel representou a maior parcela no custo final de producao. A participacao das variaveis fixas apresentou comportamento linear positivo em funcao do aumento na altura dos pastos, se mostrando sensivel a reducao da escala de producao. Houve reducao do custo de producao anual por hectare com aumento da altura de pastejo. Nao foram detectadas diferencas nos indicadores economicos determinados, e os quatro sistemas remuneraram o capital investido.
