Netto, Antonio Joelson; De Azevedo Silva, Aderbal Marcos; Bezerra, Leilson Rocha; De Barros Carvalho, Ariádne; Da Silva Agostini, Deuber LinconMade available in DSpace on 2022-04-29T08:46:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Context: Urea is widely used in ruminant diets as a source of non-protein nitrogen (NPN), partially substituting for true protein in feed, but high levels of urea in the diet may cause toxicity. Aims: This study investigated the microencapsulation of urea in carnauba wax for slow release in the rumen to...

Soares, Kallyne Sousa; Souza, Marthyna Pessoa; Silva-Filho, Edson C.; Barud, Hernane Silva; Ribeiro, Clóvis Augusto [UNESP]; Santos, Diógenes DiasMade available in DSpace on 2022-05-01T11:07:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-12-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); The production of edible film from onion (Allium cepa L.) to be applied as packaging is attractive, due to its chemical properties and biodegradable characteristics. Thus, we tested the hypothesis that edible onion film can positively influe...
Performance, body composition and net requirements of protein and energy for we...
Rocha, Tiago Cunha; Fontes, Carlos Augusto de Alencar; Processi, Elizabeth Fonsêca; Bendia, Laila Cecília Ramos; Silveira Filho, Clóvis CarlosThis research aimed to evaluate the performance, body composition and net requirements for protein and energy in grazing Nellore steers supplemented with or without addition of lipids. Twenty-eight steers, 301 ± 5.8 kg BW, were used in the experiment. The comparative slaughter method was used, with four steers used as references. The remaining 24 steers were randomly distributed into four groups, during 180 day...
Evaluation of methodologies of urine collection to estimate microbial synthesis...
Bendia, Laila Cecília Ramos; Fontes, Carlos Augusto de Alencar; Processi, Elizabeth Fonsêca; Silveira Filho, Clóvis Carlos; Lombardi, Cláudio TeixeiraThis study investigated the effectiveness of the urine sample collection method in predicting the volume urinary and synthesis of microbial nitrogen. Eight fistulated steers were used with accessible rumens and kept in individual stalls. Their diets consisted of corn silage; corn silage + concentrate; corn silage + concentrate with addition of lipids in the form of soybean oil; and corn silage + concentrate wit...
Growth performance and carcass traits of young nellore bulls supplemented with ...
Silveira Filho, Clóvis Carlos; Fontes, Carlos Augusto de Alencar; Processi, Elizabeth Fonsêca; Bendia, Laila Cecília RamosThe aim of research was to evaluate the performance and characteristics of the carcasses of Nellore young bulls in grazing supplemented with or without addition of lipids. Twenty–eight young bulls, 301 ± 5.8 kg in body weight, which four constituted the reference group and the twenty-four remnants were used in the experiment and randomly distributed into four groups according to treatment: only Panicum maximum ...
Intake, nitrogen balance and microbial protein synthesis of steers fed with or ...
Bendia, Laila Cecília Ramos; Fontes, Carlos Augusto de Alencar; Processi, Elizabeth Fonsêca; Silveira Filho, Clóvis Carlos; Lombardi, Cláudio TeixeiraThis study investigated the influence of energy supplementation with or without the addition of lipids on microbial production, microbial synthesis efficiency and nitrogen balance. Eight fistulated steers were used with accessible rumens and kept in individual stalls. Their diets consisted of corn silage; corn silage + concentrate; corn silage + concentrate with addition of lipids in the form of soybean oil; an...

Silveira Filho, Clóvis Carlos; Fontes, Carlos Augusto de Alencar; Processi, Elizabeth Fonsêca; Bendia, Laila Cecília Ramos; Lombardi, Cláudio TeixeiraThe aim of research was to evaluate the meat quality of Nellore young bulls in grazing supplemented with or without addition of lipids. Twenty–four young bulls, 301 ± 5.8 kg in body weight, were used in the experiment and randomly distributed into four groups according to treatment: only Panicum maximum cv. Mombasa grass; Mombasa grass with concentrated supplementation based on soybean meal; Mombasa grass with ...
Changes in hematological biomarkers of Nellore cows at different reproductive s...
Oliveira, Wagner Dias Coelho de; Dias e Silva, Tairon Pannunzio; Araújo, Marcos Jácome de; Edvan, Ricardo Loiola; Oliveira, Ronaldo LopesThis study was conducted to evaluate changes in hematological biomarkers of Nellore cows at different reproductive stages. Fifteen multiparous cows with 4 ± 1 years of age and live weight of 400 ± 50 kg were used at different stages (non-pregnant, in the initial, middle and late pregnancy, at birth, one day postpartum, 30 and 60 days postpartum). Blood collections were performed every 30 days and assayed for th...
Cama de frango e suplemento à base de microbiota ruminal em dietas de novilhas ...
Pereira, José Carlos; Silva, Paulo Roberto de Carvalho e; Cecon, Paulo Roberto; Resende Filho, Moisés de Andrade; Oliveira, Ronaldo LopesO trabalho foi conduzido para avaliar o desempenho de novilhas de rebanhos leiteiros recebendo dietas contendo cama-de-frango (CF) e suplemento à base de microbiota ruminal (SMR). Foram utilizadas 20 novilhas mestiças Holandês-zebu, com peso médio inicial de 276 kg e idade média de 13,8 meses. Os animais foram distribuídos aleatoriamente em arranjo fatorial 2x2, no qual foram estudados dois níveis de CF (15 e 3...
Características ruminais e eficiência de síntese microbiana em novilhos aliment...
Oliveira, Ronaldo Lopes; Pereira, José Carlos; Silva, Paulo Roberto de Carvalho e; Euclydes, Ricardo FredericoO experimento foi realizado para avaliar o efeito de dois níveis de cama de frango (15,0 e 30,0%), associada ou não a um suplemento à base de microbiota ruminal liofilizada de bovinos adultos (0 e 10 g/anim.dia), na alimentação de novilhos Holandês/Zebu. Quatro novilhos fistulados no rúmen e abomaso foram distribuídos em quadrado latino 4 x 4 em arranjo fatorial 2 x 2 (nível de cama de frango x com ou sem micob...
