13. Feedlot performance, feed efficiency and carcass traits in Nellore cattle selected for postweaning weight
The objective of this study was to evaluate the correlated responses to selection for growth in feed efficiency and carcass traits of Nellore animals. A total of 121 animals of the Nellore control (NeC) and selection herds were subjected to performance testing and classified regarding residual feed intake (RFI). Sixty-seven of these animals were selected and

15. Prediction of retail beef yield, trim fat and proportion of high-valued cuts in Nellore cattle using ultrasound live measurements
The objective of this study was to develop equations to predict retail product and fat trim (weights and percentages) for Nellore (Bos indicus) cattle. Live ultrasound measurements of the longissimus muscle area, backfat thickness at the 12th rib and rump fat depth and shrunk body weight were obtained from 218 Nellore steers to predict weights and percentage

16. Residual feed intake and its effect on carcass and meat characteristics of feedlot Zebu cattle
The objective of this study was to evaluate the residual feed intake (RFI) and its relation with performance, carcass and meat characteristics of Zebu animals. A total of 40 Zebu steers with initial age of 18 months and initial live weight of 350 kg were confined in feedlot for 112 days. The average daily gain (ADG) and dry matter intake (DMI) were obtained

17. Net requirements of energy, protein and macrominerals for weight gain of grazing beef cattle castrated at different ages, with and without supplementation
The objective of this experiment was to estimate the requirements of energy, protein and macrominerals of grazing crossbreds calves, in Brachiaria decumbens Stapf pasture, castrated at different ages, with and without supplementation. Forty-seven young calves at initial age of 120±30.1 days and 115.3±1.97 kg of live weight were used. To estimate net energy

18. Corn silage with and without enzyme-bacteria inoculants on performance, carcass characteristics and meat quality in feedlot finished crossbred bulls
Two height cuttings of corn silage with or without enzyme inoculants were evaluated for 68 days on performance, carcass characteristics, meat quality and chemical composition of the Longissimus muscle in crossbred bulls (F1 - ½ Nellore vs. ½ Angus) finished in feedlot. Thirty-two 20-month-old bulls, with initial average weight of 374±25 kg, were kept in i

19. Morfogênese, acúmulo de forragem e teores de nutrientes de Panicum maximum cv. Tanzânia submetido a diferentes severidades de desfolhação e fertilidades contrastantes / Morphogenesis, forage net accumulation and nutritional status of Panicum maximum cv Tanzânia under contrasting fertilization rates and grazing intensities
Nitrogen is the most important nutrient regulating pasture production. Response to N fertilization depends on residual leaf area index and other nutrient availability. The aim of this study was to evaluate morphogenetic and structural characteristics, grazing interval, forage yield and nutritional status of Tanzania guinea grass under contrasting defoliation

20. Análise da relação entre contratos futuros agropecuários e mercado de ações com foco em períodos de crise / An analysis of the relationship between commodity futures contracts and the stock market focused on crisis periods
Mais do que uma ferramenta para gestão do risco de preços para produtores e consumidores, os contratos futuros agropecuários tem se tornado uma importante opção de investimento principalmente em períodos de crise quando os riscos no mercado de ações aumentam. No Brasil, a participação de investidores no mercado futuro agropecuário ainda é pequena

21. Suplementação com análogo de metionina HMB (2-Hidroxi-4-(Metil) ácido Butânico) em dieta de bovinos da raça Nelore terminados em confinamento / Supplementation with HMB (2-hydroxy-4-(methyithio) Butanoic acid) methionine analog in diet of Nellore cattle finished in feedlot
Two experiments were conducted to evaluate the inclusion of levels of HMB (DL, 2-hydroxy-4-(methyl) botanical acid) methionine in diets of Nellore beef cattle finished in feedlot. In Experiment 1, 128 male, unneutered Nellore animals, with initial weight of 290 kg ( 20,50), were housed for 111 days (21 days of adaptation and 90 days of experiment) in 16 pens

22. EXPORT OF LIVE CATTLE IN THE STATE OF PARÁ: MAPPING ON SUPPLY CHAIN AND LOGISTICS ITS PROCESSES / EXPORTAÇÃO DE BOVINOS VIVOS NO ESTADO DO PARÁ: MAPEAMENTO DE UMA CADEIA DE SUPRIMENTOS E DE SEUS PROCESSOS LOGÍSTICOS
O mercado de exportação de Bovinos Vivos surgiu e cresceu nos últimos anos, promovendo a movimentação significativa do agronegócio como um todo, com destaque a pecuária Brasileira e particularmente a Paraense. Tal crescimento fez o Brasil se posicionar entre os maiores exportadores de bovinos vivos, que, aliado à ausência de pesquisas em Engenharia

23. Avaliação in vivo da eficiência de dois imunógenos recombinantes derivados do peptídeo SBm7462 para o controle do carrapato Rhipicephalus (Boophilus) microplus (Canestrini 1887) / Evaluation efficacy in live of two recombinant immunogens derivatives of peptide SBm7462 in the control of the tick Rhipicephalus (Boophilus) microplus (Canestrini 1887)
Recombinant peptides rBmseq1 and RBmseq4 were evaluated as immunogenic for the control of ticks R. (B. ) microplus in test of stable. We used 17 bovine animals of the half-breed average degree of blood of 7/8 (H/Z), which were kept under the management routine in the Sector of isolation of bovine animals in the Department of Veterinary UFV. The animals were
