Resumo: | It was aimed to evaluate the effect of the rumen degradable protein (RDP) and supplementation frequency on the consumption and digestibility of the nutrients, concentration of amoniacal nitrogen (N-NH3), ruminal pH and nitrogen compounds excreted in the urine (NUR) and serum (NS) in bovine in pasture of Brachiaria brizantha cv. Marandu during the rainy/dry transition period. Five crossbred steers, castrated, with average body weight of 350 kg, cannulated in the rumen, were used. The experiment used in Latin square design 5 X 5, with duration of 21 days each experimental period. The treatments were: SAL - mineral mix supplied ad libitum (Controls); daily RDP: supplement formulated to meet the requirements RDP, with daily supply; frequency RDP: supplement formulated to meet the requirements RDP, supplied three times on week (Mondays, Wednesdays and Fridays); RDP+: supplement formulated with increment of 10% of the requirements of RDP supplied 3X; RDP-: supplement formulated with less 10% of the requirements of RDP supplied 3X. There was statistical difference for dry matter intake (DMI), forage (CFO) and neutral detergent fiber (NDF) and apparent digestibility of DM and NDF with treatment effect (p <0.05), after being checked by statistically significant contrast analysis (p <0.05) between supplements (Ps vs. RDP daily). Providing multiple supplementation increased or reduced by 10% in RDP requirements of animals and controlled add-frequency did not affect (P> 0.05) DMI and apparent digestibility of DM, CP and NDF. The ruminal pH was different between the frequency RDP supplements vs. RDP- time 4 hours on day no supplementation. The ruminal ammonia concentration of the supplemented animals showed a difference between the RDP daily supplements vs. RDP frequency; RDP frequency vs. RDP +; RDP frequency vs. PDR-. The nitrogen serum concentration is larger (P <0.10) in animals consuming multiple supplements with increment of 10% of the requirements of RDP. |

Objetivou-se avaliar o efeito da proteína degradável no rúmen (PDR) e frequência de suplementação sobre o consumo e digestibilidade dos nutrientes, concentração de nitrogênio amoniacal (N-NH3), pH ruminal e compostos nitrogenados excretados na urina (NUR) e sérico (NS) em bovinos em pastagem de Brachiaria brizantha cv. Marandu durante o período de transição águas-seca. Foram utilizados cinco bovinos mestiços, castrados, com peso corporal médio inicial de 350 kg, fistulados no rúmen. Utilizouse o delineamento em quadrado latino 5 X 5, com duração de 21 dias cada período experimental. Os tratamentos avaliados foram: SAL - mistura mineral fornecida ad libitum (Controle); PDR diário - suplemento formulado para atendimento das exigências em PDR, com fornecimento diário; PDR frequência- suplemento formulado para atendimento das exigências em PDR fornecido três vezes por semana ( segundas, quartas e sextas -feiras); PDR+ - suplemento formulado com acréscimo de 10% nas exigências em PDR fornecido 3X; PDR- - suplemento formulado com 10% a menos da exigência em PDR fornecido 3X. Verificou-se diferença estatística para os consumos de matéria seca (CMS), forragem (CFO) e fibra em detergente neutro (CFDN) e para digestibilidade aparente da MS e FDN com efeito de tratamento (P<0,05), sendo posteriormente verificado pela análise de contraste estatisticamente significativo (P<0,05) entre os suplementos (Sal vs. PDR diário). O fornecimento de suplementação múltipla com acréscimo ou redução em 10% nas exigências em PDR dos animais e com frequências controladas do suplemento não afetou (P>0,05) o CMS e a digestibilidade aparente da MS, PB e FDN. O pH ruminal apresentou diferença entre os suplementos PDR frequência vs. PDR- no tempo 4 horas em dia de não suplementação. A concentração de amônia ruminal dos animais suplementados apresentou diferença entre os suplementos PDR diário vs. PDR frequência; PDR frequência vs. PDR+; PDR frequência vs. PDR-. A concentração de nitrogênio sérico é maior (P<0,05) em animais consumindo suplementos múltiplos com acréscimo de 10% das exigências de PDR.
