“…The values obtained in this study for rumination efficiency in g DM/h corroborates those verified by Vieira et al (2011), who found no significant difference for this parameter when soybean meal was substituted by DCBM at the levels of 0; 50; 75 and 100% with respective means of 198. 06; 202.75; 197.14 and 224.19 g DM/hour.…”

“…The values obtained in this study for DM intake corroborate those verified by Vieira et al (2011), who found no significant difference for this parameter when substituting soybean meal by detoxified castor bean meal at the levels of 0; 50; 75 and 100% with respective means of 1550; 1490; 1530 and 1490 g/animal/day, confirming that the use of this co-product in the feeding of sheep does not limit DM intake.…”

“…In the evaluations of the ingestive behavior of Morada Nova crossbred sheep, fed diets containing levels of detoxified castor bean meal similar to those evaluated in this study, Vieira et al (2011) found an interaction between the evaluation periods and the time spent in activities of feeding, rumination and idle. In this situation, the shortest feeding time was observed in animals receiving diets with 0 and 100% of substitution of soybean meal by detoxified castor bean meal, in the period from 17 to 20 hours.…”

Castor bean crops stand out in the Northeastern Brazil for oil production, producing coproducts with potential for animal diets. Thus, this work evaluated the effect on ingestive behavior when 0, 33, 67 and 100% of detoxified castor bean meal (DCBM) were included to substitute soy bean meal in diets for sheep. The randomized blocks design was used with five sheep in each treatment. Dry matter intake and neutral detergent fiber intake were not affected (P > .05) by the inclusion of DCBM in the diet, with means of 1362.6 and 582.98 g/animal/day, respectively. Substitution of soybean meal by DCBM did not affect (P > .05) times of rumination, idle and total chewing, with averages of 181.33, 347.04 and 366.24 minute/12 h, respectively. A quadratic effect (P < .05) was found for feeding time, with minimum of 164.56 min/12 h, when 60% of DCBM was included in the diet. A quadratic effect (P < .05) was verified for eating efficiency with maximum of 4.43 g DM/minute and 2.08 g NDF/minute. Rumination efficiency in g DM and NDF/minute were not affected (P < .05), with means of 4.31 and 1.84, respectively. The substitution of soybean meal by DCBM decreases feeding time when 60% of it was used but does not influence the intake of DM and NDF, time spent in ruminating and idle, and total chewing time. The use of 60% of DCBM increases feeding efficiency of DM and NDF, and does not compromise the efficiency of rumination.

“…Regarding the time spent in rumination, the intervals between 11 and 15 h were the first It was possible to observe that in all treatments the rumination process started one to two hours after feed intake. According to Vieira et al (2011) the rumination peaks between 01h and 07h are due to the rest of the animals, where the activities alternate between the processing of the ingested food and idleness (Figure 2). concentrates, because the greater proportion of hay promotes the faster filling of the rumen, leading the animals to idle state .…”

Feeding behavior of goats, castrated and uncastrated, supplemented with Vitamin E

et al. 2019

The objective of this study was to evaluate the ethological and feeding behavior of male goats under the influence of climatic conditions, castration and supplementation with Vitamin E. The responses were analyzed by a behavior test factorial design with 2 x 2 (not spayed or neutered animal, the presence or absence of supplementation with Vitamin E), with 6 replicates. The time of feed intake, rumination, other activities, entertainment, salt intake frequency, water, urination and defecation were evaluated. The factors did not have any effect on the animal’s condition, or the vitamin supplementation (P>0.05) on rumination, other activities, defecation frequency and water consumption. Vitamin E intake had no effect on food and entertainment (P>0.05). There was a significant condition of the animal (P<0.05) on the salt intake and urination, for uncastrated animals without Vitamin E. Periods of the day (P<0.05) affected feed intake in all treatments. There was a significant difference (P<0.05) for rumination time. Vitamin E had little influence on ethological behavior, and castration is directly linked to the behavioral parameters of goats.

“…Isso pode ser explicado pela ausência de variação significativa no consumo de MS e de FDN, e pela condição isonutricional das dietas testadas. Resultados semelhantes foram observados por Vieira et al (2011) que ao trabalharem com borregos Morada Nova alimentados com dietas contendo 0; 50; 75 ou 100% de farelo de mamona autoclavado em substituição ao farelo de soja não verificaram diferenças quanto ao consumo de MS, tempos de alimentação e de ruminação, eficiências de alimentação e de ruminação, tempo de mastigação total, número de bolos ruminais, tempo de mastigação merícica por bolo ruminal e número de mastigações merícicas por bolo. O tempo de alimentação dos animais recebendo a dieta NT foi semelhante ao dos animais recebendo as rações com torta de mamona tratada, não se confirmando Como a composição química das dietas foi próxima, assemelhando-se, assim, na densidade nutricional, os animais atingiram suas exigências nutricionais em tempos similares, não ocorrendo diferenças no tempo em ócio.…”

RESUMO -A torta de mamona tem potencial para utilização na alimentação de ovinos em regiões semiáridas, mas apresenta como limitação a ricina, que pode causar intoxicação. Objetivou-se avaliar influência de dietas contendo torta de mamona em comportamento ingestivo, consumo e desempenho em ovinos. Foram distribuídos 20 ovinos Morada Nova em blocos ao acaso (dois blocos) com cinco tratamentos (torta de mamona não tratada, tratada com calcário calcítico, com ureia, com fosfato monobicálcico e autoclavada) e quatro repetições. O consumo dos nutrientes não foi influenciado pelos tratamentos de destoxificação, além dos animais não terem apresentado sintomas de intoxicação. Quanto ao comportamento ingestivo, não houve diferença para a maioria das variáveis entre tratamentos, bem como não se confirmou possível rejeição dos ovinos pela torta não tratada. Foi observado que os animais alimentados com dieta contendo torta de mamona autoclavada apresentaram desempenho superior aos que receberam torta não tratada. Apesar dos animais alimentados com torta de mamona tratada com fosfato monobicálcico não terem sido superiores aos alimentados com torta não tratada, apresentaram ganho médio diário 27,3% maior, consumiram menos 10,5% de alimento para ganhar 1 kg e, para ganharem 12 kg, precisaram de 24 dias a menos. A terminação de ovinos utilizando dietas contendo torta de mamona autoclavada apresenta resposta superior à terminação desses animais alimentados com dietas contendo torta de mamona não tratada ou destoxificada com ureia. Além disso, animais terminados com dietas contendo torta destoxificada com fosfato monobicálcico ou calcário calcítico apresentam resposta intermediária. Palavras-chave: Ricinus communis L.. Destoxificação. Ganho médio diário.ABSTRACT -Castor cake shows potential for use in sheep feed in semi-arid regions, but as a limitation, contains ricin, which can cause poisoning. The aim of his study was to evaluate the influence of diets containing castor cake on feeding behaviour, intake and performance in sheep. Twenty Morada Nova sheep were distributed into two randomised blocks with five treatments (untreated castor cake, castor cake treated with limestone, with urea, with monodicalcium phosphate and autoclaved) and four replications. Nutrient intake was not influenced by the detoxification treatments, with the animals displaying no symptoms of poisoning. There was no difference in feeding behaviour between treatments for most of the variables, and the possible rejection of the untreated cake by the sheep was not confirmed. It was found that animals fed diets containing autoclaved castor cake performed better than those which received untreated cake. Although the animals fed castor cake treated with monodicalcium phosphate were not superior to those fed untreated cake, they had a 27.3% greater average daily gain, consumed 10.5% less feed to gain 1 kg, and took 24 days less to gain 12 kg. The finishing of sheep fed diets containing autoclaved castor cake shows a superior response to the finishing of these an...
