Pełny tekst źródłaTannins increased the excretion of nitrogenous compounds and sialic acid, and reduced nutrient digestibility of most feeds tested, as measured by the4 poultry model. Tannins reduced the proportion of uric acid nitrogen in the excreta. Tannins in lotus reduced intestinal digestion of N as measured by mobile bag and in vitro methods. Nitrogen digestibility of soyabean meal and chickpea as measured by the mobile bag and in vitro methods was not affected by QT. Mimosa tannin (MT) inhibited the attachment of microbes to cellulose and decreased gas production. Polyethylene glycol completely restored the gas production from cellulose treated with MT. Pectin improved microbial attachment in the presence of MT, and the inhibition of the gas production from cellulose was partially restored. The gas production from maize shoots decreased with MT, and it was restored with the addition of PEG. Pectin did not improve the gas production from MT-treated maize shoots. The presence of both MT and pectin improved EMPS, but reduced the incorporation of 15N into microbial protein.

Pełny tekst źródłaThe objective of this trial was to evaluate the effects of polyclonal antibodies preparation (PAP) against specific rumen bacteria Streptococcus bovis and Fusobacterium necrophorum on rumen fermentation parameters in ruminally cannulated cows adapted or not to highly fermentable carbohydrates diets (HFC) after an acidosis challenge. The experimental design was two 3X3 Latin squares in a factorial arrangement of treatments 3X2 regarding two feed additives (PAP in powder presentation - PAPP and PAP in liquid presentation - PAPL) plus control group (CON) and two managements of diets adaptation, resulting in six treatments. The first Latin square had a step-up diet adaptation: from D0 to D4 100% forage; D5 to D9 30% of concentrates and D10 to D14 60% of concentrates. The second Latin square received 100% forage from D0 to D14. On D15 and D16, all animals received a diet with 80% of concentrates. For analysis, rumen fluid was sampled at 0 and every 3 h posfeeding totaling 36 h (D15 and D16) of challenge with a diet with 80% of concentrates. Data were analyzed by MIXED procedure with a significance level of 0.05. An interaction between time and adaptation (P<0,05) was observed for ruminal pH. At 0, 3, 6, 9, 12 and 36 h postfeeding, the non-adapted group had higher values compared to the adapted group and at 24 h postfeeding, the inverse was observed. For total short-chain fatty acids concentration, at 0, 3, 6, 9 and 36 h postfeeding, the adapted group had higher values compared to non-adapted group. For molar proportion of acetate at 0h postfeeding, the non-adapted group had higher values than the adapted group, and at 24, 27 and 30h, the adapted group had greater values than the non-adapted group. For molar proportion of propionate the non-adapted group had greater values compared to the adapted group from 3 to 36h postfeeding. For acetate:propionate (Ac:Pr) ratio at 6, 12, 24, 27, 30 and 36 h postfeeding, the adapted group had greater values compared to the nonadapted group. For butyrate molar proportion at 0, 3, 6, 9, 12, 33 and 36h postfeeding the adapted group had greater values than the non-adapted group. For ammonia nitrogen (NH3- N) concentration at 6h, the non-adapted group had greater values than the adapted group (26.1 vs. 19.3, respectively), however at 9, 30, 33 and 36h postfeeding, the adapted group had higher values compared to the non-adapted group. It was also observed an interaction between time and additive (P=0.0430) for butyrate molar proportion, but when the analysis was performed by time no effect was observed. For the relative values of protozoa measured (Dasytricha, Isotricha, Epidinium, Diplodinium and Entodinium) only Entodinium presented adaptation effect (P<0.0236) with a higher proportion in the adapted group. Haptoglobin values was also not influenced (P>0.05) by additive or adaptation effect. Polyclonal antibodies preparation was not as effective as the gradual adaptation to the diet high concentrate to control changes of ruminal parameters.

Pełny tekst źródłaL'obiettivo di questa tesi era di determinare l'effetto degli integratori lievito sulle prestazioni e la salute dei bovini da carne durante il periodo di ricevimento e finissaggio. Inoltre, un altro obiettivo di questo studio era di valutare l'applicabilità di ruminocentesi sui bovini da carne e la possibilità di utilizzare l'ecografia transaddominale della mucosa ruminale come uno strumento diagnostico non invasivo per identificare i bovini affetti da SARA. Tre prove sono state condotte al fine di fare raggiungere questo obiettivo. Trail I e II sono stati condotti simultaneamente utilizzando gli stessi animali, mentre per la terza prova utilizzato un campione più grande, ma sempre nella stessa azienda zootecnica. Trail I e II ha valutato l'effetto della supplementazione alimentare di pareti di lieviti (JWC) e lievito cellule vive (LY) a diversi dosaggi di metaboliti nel rumine. Sessanta vitelloni di razza Charolaise sono stati divisi in due gruppi sulla base della loro fase di alimentazione: accrescimento e finissaggio. Il fluido ruminale è stato raccolto al tempo zero e dopo 21 e 42 giorni del periodo sperimentale al fine di valutare le concentrazioni degli acidi grassi volatili e del pH. I campioni di feci sono stati raccolti prima (T0), dopo il 21 (T1) e 42 (T2) giorni dall'inizio dello studio, e sono stati analizzati per sostanza secca (DM), ceneri, proteina grezza (CP), estratto etereo (EE), fibra neutra detergente (NDF), fibra detergente acido (ADF), acido detergente lignina (ADL) e amido.I risultati ottenuti suggeriscono che la supplementazione di lievito non hanno effetti benefici con tutti i tipi di condizione di dieta. L'analisi statistica dei dati di VFA ha mostrato un effetto significativo di tempo (P <.05) su tutti i parametri studiati, eccetto l'acido iso-Valerianico sia nei gruppi di crescita e di finissaggio. 408/5000 Sono stati riscontrati cambiamenti tra sottogruppi crescita (P <.05) su acido propionico, acido acetico, acido iso-butirrico e l'acido n-butirrico, mentre non è stata trovata significatività statistica tra sottogruppi del finissaggio. Trail III è stato condotto su 478 bovini da carne di razza Charolaise, sono stati monitorati per tre volte durante il ciclo di bestiame al fine di valutare il pH del fluido ruminale e per valutare le misure della parete ruminale.Effetto Periodo (P <0.001) è stato riscontrato tra i tre periodi dopo 10 giorni dall'arrivo. Valori di pH ruminale erano inferiori al valore di soglia di 5.71 in T0 rispetto al T1 e T2. L'analisi di Pearson ha mostrato interazione tra il pH e spessore ad ultrasuoni totale di parete ruminale (-0,700; p <0,0001) e del rumine mucosa (-0,7921; p <0,0001). Lo studio dimostrano che l'ecografia transaddominale della mucosa ruminale ha il potenziale per essere uno strumento diagnostico adatto per identificare i tori da ingrasso affetti da SARA.

Os objetivos deste trabalho foram verificar os efeitos das relações amido:fibra solúvel em detergente neutro (FSDN) das dietas sobre os parâmetros ruminais, digestivos e de desempenho de ovinos Dorper x Santa Inês. As dietas foram caracterizadas pelas altas concentrações de amido (25%MS) ou de FSDN (25%MS) ou concentrações equivalentes destes nutrientes (18%amido+18%fibra solúvel na MS). No primeiro experimento foram utilizados seis borregos canulados ruminalmente, distribuídos em delineamento quadrado latino duplo (3 dietas x 3 períodos) para avaliação ruminal da concentração de amônia, pH e qualificação de massa microbiana. O segundo experimento avaliou o consumo, a digestibilidade total da matéria seca e dos nutrientes e os balanços de nitrogênio e energia das dietas experimentais, utilizando 15 borregos distribuídos em delineamento inteiramente casualizado. No terceiro experimento realizou-se um confinamento utilizando 24 borregos não castrados distribuídos em delineamento em blocos completos casualizados. Após 74 dias de confinamento os animais foram avaliados quanto ao ganho em peso, consumo, conversão e eficiência alimentar. Posteriormente foram abatidos e avaliados quanto ao peso de abate, características de carcaças e composição química do músculo Longissimus. Os valores de pH (6,29) não diferiam (P>0,05) entre as dietas enquanto que a maior concentração de amônia foi encontrada para a dieta com 25% de FSDN. Aproximadamente 60% dos microrganismos ruminais estavam associados a fase líquida, contudo as dietas não interferiram (P>0,05) na população microbiana ruminal. Elevados coeficientes de digestibilidade foram observados, independentementemente do tipo de carboidrato solúvel utilizado em maior proporção. O consumo de matéria seca foi menor para a dieta FSDN (1,075 kg) quanto comparado às demais dietas, afetando a maioria das variáveis...
The objective of this study was to evaluate the effects of dietary starch:neutral detergent soluble fiber (NDSF) relation on ruminal, digestibility and performance of Dorper x Santa Inês ram lambs. The diets were characterized by high concentrations of starch (25% DM) or NDSF (25% DM) or equivalent concentrations of these nutrients (18% starch +18% soluble fiber at MS). In the first experiment six lambs with ruminal cannula were used, distributed in Latin square design (3 diets x 3 periods) to assess ruminal ammonia concentration, pH and classification of microbes. The second experiment assessed intake, total digestibility of dry matter and nutrients and nitrogen balance and energy of diets, using 15 lambs distributed in a completely randomized design. In the third experiment ram lambs were distributed in a complete randomized block design. After 74 days of confinement all animals were evaluated weight gain, intake, feed conversion and efficience. Later were slaughter and evaluated by slaughter weight, carcass characteristics and Longissimus chemical composition. Average pH (6.29) did not differ (P>0.05) amoung diets while the highest concentration of ammonia was found for the diet with 25% of NDSF. Approximately 60% of ruminal microorganisms were associated with the liquid phase, however the diets did not affect (P>0.05) ruminal microbial populations. High digestibility coefficients were observed, regardless of the type of soluble carbohydrate used. Dry matter intake was lower (P<0.05) for NDSF (1.075 kg) compared to the other diets, affecting most of the performance variables. It is recommended the use of diets with 18% starch and 18% of fsdn to sheep fed high proportions of concentrate
