Short-term changes in plasma and milk fatty acid profiles in cows fed chopped e...
Lopes, Fernando César Ferraz; Ribeiro, Carlos Gustavo Santos; Rodriguez, Norberto Mario; Gama, Marco Antônio Sundfeld da; Morenz, Mirton José FrotaThe study was carried out in a randomized block design, in a 2 x 2 factorial arrangement, with the aim to evaluating during 21 days the short-term changes in plasma and milk fatty acid (FA) profile in Holstein x Gyr cows (444±84 kg; 75±31 days in milk; 15.4±4.8 kg day-1 of milk) fed 600 g kg-1 DM chopped elephant grass-based diets supplemented with 45 g kg-1 DM sunflower oil (SO). Two types of SO were evaluated...

Lopes, Fernando César Ferraz; Ribeiro, Carlos Gustavo Santos; Rodriguez, Norberto Mario; Gama, Marco Antônio Sundfeld da; Morenz, Mirton José FrotaTwo experiments were carried out in a 2 x 2 factorial arrangement with the objective of evaluating two methods of concentrate feeding for Holstein x Gyr cows fed 600 g kg-1 chopped elephantgrass-based diets supplemented at 45 g kg-1 DM with two types of sunflower oil (SO). The types of SO differed in the levels of oleic and linoleic fatty acids (FAs): high oleic/low linoleic acid – HO (73 and 10 g 100 g-1 FA, r...
Butter fatty acid composition as a function of soybean oil supplementation and ...
Lopes, Fernando César Ferraz; Ribeiro, Carlos Gustavo Santos; Rodriguez, Norberto Mario; Gama, Marco Antônio Sundfeld da; Morenz, Mirton José FrotaThe aim of this study was to evaluate the performance of cows fed with a total mixed ration composed of elephant grass and a concentrate containing 0.0% (control), 1.5%, 3.0% or 4.5% soybean oil on a dry matter basis. The effect of milking time (morning versus afternoon) on butter fatty acid composition was also evaluated. Twelve multiparous Holstein x Gyr cows with an average milk production of 18.0±4.6 kg day...

Ribeiro, Carlos Gustavo Santos; Lopes, Fernando César Ferraz; Rodriguez, Norberto Mario; Gama, Marco Antônio Sundfeld da; Morenz, Mirton José FrotaThe aim of this study was to evaluate the ruminal parameters of fermentation and degradation, kinetic flow of rumen digesta, and milk fatty acid composition of cows fed 52% chopped elephantgrass-based diets containing 0.0% (control), 1.5%, 3.0% and 4.5% soybean oil (SO) on a dry matter (DM) basis. Four rumen-cannulated Holstein x Gyr dairy cows with an average milk production of 15.6 ± 3.0 kg day-1 and 90 ± 25 ...
Fatty acid composition of milk from Holstein x Gyr cows grazing on marandu gras...
Silva, Bárbara Cardoso da Mata e; Rodriguez, Norberto Mario; Morenz, Mirton José Frota; Gomide, Carlos Augusto de Miranda; Martins, Carlos EugênioThe inclusion of plant oils in the diets of grazing cows represents a promising nutritional strategy for the production of milk naturally enriched with bioactive compounds, such as rumenic (cis-9, trans-11 CLA), vaccenic (trans-11 C18:1) and oleic (cis-9 C18:1) acids. The aim of this study was to evaluate the effect of dietary supplementation with sunflower oil (SO) on the fatty acid (FA) composition of milk fr...
2,6-Diaminopimelic acid (DAPA) in microbial protein quantification of heifers f...
Couto Filho, Cristovão Colombo de Carvalho; Saliba, Eloísa de Oliveira Simões; Rodriguez, Norberto Mario; Barbosa, Geraldo Sérgio Senra CarneiroThe objective of this study was to evaluate the flow of nitrogenous compounds, protein degradability, rumen degradation of total carbohydrate and organic matter and microbial efficiency in heifers subjected to diets containing corn silage, sugarcane or Tifton. For this purpose, the 2,6-diaminopimelic acid (DAPA) technique was adopted and analytical procedures for amino acids by HPLC were adapted. Six rumen-fist...
Chemical composition and ruminal degradation kinetics of crude protein and amin...
Miranda, Lidia Ferreira; Rodriguez, Norberto Mario; Pereira, Elzânia Sales; Queiroz, Augusto César de; Sainz, Roberto DanielThe objective of this research was to determine the chemical composition and ruminal degradation of the crude protein (CP), total and individual amino acids of leaves from tropical forages: perennial soybean (Neonotonia wightii), cassava (Manihot esculenta), leucaena (Leucaena leucocephala) and ramie (Boehmeria nivea), and to estimate the intestinal digestibility of the rumen undegradable protein (RUDP) and ind...

Veloso, Cristina Mattos; Rodriguez, Norberto Mario; Carvalho, Gleidson Giordano Pinto de; Pires, Aureliano José Vieira; Mourão, Gerson BarretoForam determinadas as degradabilidades in situ da MS e PB dos folíolos de três leguminosas tropicais leucena (Leucaena leucocephala (Lam.) de Wit), guandu (Cajanus cajan (L.) Millsp.) e soja perene (Neonotonia wightii) e de folhas de outras duas forrageiras tropicais rami (Boehmeria nivea (L.) Gaudich) e mandioca (Manihot esculenta Crantz). Amostras de 3 g (guandu, soja e rami) ou 5 g (leucena e mandioca) do ma...

Evaluation of silages from hybrid m734 of sunflower obteined in diferent cuttin...
Pereira, Luiz Gustavo Ribeiro; Maurício, Rogério Martins; Gonçalves, Lúcio Carlos; Tomich, Thierry Ribeiro; Rodrigues, José Avelino SantosPara que o girassol possa ser utilizado com sucesso na forma de silagem, é necessário que se determine o ponto ideal de ensilagem. O objetivo desse experimento foi avaliar através da técnica in vitro semi-automática de produção de gases a cinética de degradação da matéria orgânica (MO) e matéria seca (MS) das silagens do híbrido M734 ensilado com 100, 107, 114 e 121 dias após o plantio. As leituras de pressão d...
