Fish produced in Aquaculture has been critical to the global supply of animal protein in human food. In Brazil, Aquaculture has been growing and in order for it to be consolidated it is necessary to computerize the fish production process in the field, in the processing that takes place in the industry, from the receipt of raw material to the shipment of the finished product and in the distribution sector of th...
To evaluate the bromatological composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Xaraés palisade grass (Urochloa brizantha ‘Xaraes’ syn Brachiaria brizantha) under grazing in integrated crop, livestock (ICL), and forest (ICLF) systems, we conducted an in situ degradability trial in randomized blocks with three non-lactat...
The agricultural industry is the main emitter of methane (CH4) and nitrous oxide (N2O), gases that each have a global warming potential that is greater than that of CO2 by 23 and 298 times, respectively. On a global scale, enteric fermentation from ruminant animal production (especially of cattle and sheep) is responsible for between 21% and 25% of total anthropogenic CH4 emissions. The search for effective, si...
Made available in DSpace on 2020-12-12T01:05:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; Production performance and methane production in two breeding and finishing systems in the state of Rondônia, Brazil, are evaluated. Study comprised totally randomized design, with two treatments, with 128 non-castrated heifers, mean initial weight 281.906 ± 1.69 kg. Production systems were classified b...
This study was conducted to validate the 9–11th rib cut to estimate the chemical composition of the carcass and of the empty body weight (EBW) of Zebu cattle. Nineteen Zebu steers with initial body weight of 266.5±32.2 kg were used. Four steers were slaughtered at the beginning to compose the reference group; three were fed at maintenance level, and the remaining were allotted to different planes of nutrition (...
This study was undertaken to examine production performance, pasture and milk intakes and nutrient digestibility in heifers supplemented with different levels of energy in a creep-feeding system on Urochloa decumbens Stapf pastures during the rainy-dry transition season. Fifty-one heifers with predominant Nellore genetic composition (average initial age and weight: 120 days and 133.4 ± 3.12 kg) and their respec...
Avaliou-se as características morfogênicas do Capim Tamani (Panicum maximum cv. BRS Tamani), estabelecido com sementes inoculadas ou não com Azospirillum brasilense em função de fontes de fosfato (superfosfato triplo e fosfato natural reativo de bayovar) e doses crescentes de nitrogênio (0, 75, 150, 300 e 600 kg ha-1) em delineamento inteiramente casualizado, organizado em esquema fatorial 2 x 2 x 5 com 4 repe...
Este trabalho foi realizado com o objetivo de avaliar o efeito de níveis de casca de algodão sobre o consumo e a digestibilidade aparente total dos nutrientes, a composição física e as características de carcaça e o rendimento dos cortes comerciais de novilhos confinados. Foram utilizados 18 novilhos mestiços, com peso vivo (PV) médio inicial de 230 kg. Dois animais foram abatidos no início do experimento para ...
Avaliaram-se os efeitos de suplementos múltiplos com diferentes níveis de uréia sobre o desempenho produtivo e os parâmetros nutricionais de bovinos em fase de terminação mantidos em pastagem diferida de capim-braquiária (Brachiaria brizantha cv. Marandu) no período de transição águas-seca. A disponibilidade estimada de matéria seca das pastagens variou de 16.360 a 9.358 kg/ha. Para avaliação do desempenho prod...
Com o objetivo de determinar as exigências de energia e as eficiências de utilização da energia metabolizável para ganho de peso e mantença de zebuínos, foi desenvolvido um experimento envolvendo 19 novilhos anelorados, com peso vivo médio inicial de 270 kg. Quatro animais foram abatidos ao início do experimento, para servirem de referência para estudos posteriores, três foram alimentados ao nível de mantença e...
