“…It has been observed that the use of several additives in sugarcane has brought great benefits such as increase of the nitrogenous fraction (Pires et al, 2004b;Carvalho et al, 2006a;Amaral, 2007). However, the use of alkaline additives such as sodium hydroxide and calcium oxide does not contribute to the increase of nitrogen uptake, sometimes triggering a greater effect of hydrolysis on the cell wall of roughages, improving the fiber digestibility and intake (Andrade et al,R.…”

-The objective of this study was to evaluate intake, performance and nutrient digestibility of sheep supplemented with sugarcane ensiled with four levels of calcium oxide (0.0, 0.8, 1.6 and 2.4%) and urea (1.5%), on a natural matter basis. Twenty castrated Santa Ines lambs with 24.09 kg average weight were housed in individual 1.5 m 2 pens, distributed in a completely randomized design. The diet supplied had a roughage:concentrate ratio of 70:30 and the experimental period lasted 77 days, of which 14 days were used for adaptation to the diet and three 21-day periods for data collection. No differences were observed for the average daily intake of dry matter, ether extract, neutral detergent fiber, neutral detergent fiber corrected for ash and protein, total carbohydrates, hemicellulose and total digestible nutrients. The treatment with urea showed differences for the intake (kg/day) of crude protein, acid detergent fiber and non-fibrous carbohydrates. There was no effect of diets on the digestibility of dry matter, ether extract, neutral detergent fiber, acid detergent fiber or total digestible nutrients, but there was a quadratic effect for total carbohydrates and increasing linear effect for non-fibrous carbohydrates. The calcium intake increased as the levels of calcium oxide in the sugarcane were elevated. The calcium:phosphorus ratio in the silage of calcium oxide was different from the silage with urea and control. No effect was observed for the performance characteristics of sheep. Sugarcane silages with calcium oxide levels of up to 2.4% or with urea do not improve the intake or weight gain of sheep.

ResumoO experimento foi conduzido com objetivo de avaliar o comportamento ingestivo de cordeiros alimentados com dietas contendo 0; 12,5 e 25,0% de feno de amoreira em substituição ao concentrado. Foram utilizados vinte e quatro cordeiros Ile de France, com 25 kg de peso corporal e aproximadamente 4 meses de idade, confinados, em delineamento experimental inteiramente casualizado. Os tempos diários de alimentação (242,01 min), ruminação (435,48 min) e ócio (762,50 min), o número de bolos ruminados por dia (658,36) e o tempo gasto por bolo (40,03 seg) não foram afetados (P>0,05) pelos diferentes níveis de feno de amoreira no concentrado. As ingestões voluntárias de matéria seca (1,258 kg/dia) e fibra em detergente neutro (0,302 kg/dia), assim como as eficiências de ingestão e ruminação da matéria seca (316,24 e 173,54 g/h, respectivamente) e da fibra em detergente neutro (75,89 e 41,68 g/h, respectivamente) foram semelhantes em todos os tratamentos. A mastigação merícica expressa em hora/dia (11,29) e o número de mastigação expresso por bolo (72,65) e por dia (47.638,06), assim como o número e o tempo gasto por refeição (22,02 refeições e 11,23 min/refeição), ruminação (25,95 ruminações e 17,29 min/ruminação) e ócio (41,81 ócios e 18,30 min/ócio) também não foram afetados (P>0,05). A inclusão de feno de amoreira não alterou a ruminação expressa em g de MS e FDN/bolo (1,91 e 0,46, respectivamente) e por min/kg de MS e FDN (361,51 e 1.505,78, respectivamente), bem como a mastigação total expressa em min/kg de MS e FDN (563,70 e 2.347,19, respectivamente). A utilização do feno de amoreira em substituição parcial ao concentrado, não altera o comportamento ingestivo de cordeiros em confinamento.

“…The recent progress in nutrition, reproduction, and genetic improvement has also exerted a positive influence on meat and milk production. However, a better understanding of animal behavior is needed in order to better manage food consumption, which would allow farmers to adjust the feeding of animals to improve their performance (CARVALHO et al, 2006;PIRES et al, 2009). To reduce the cost of feeding and to increase profitability, it is necessary to use alternative feeds that improve animal productivity, while also maintaining a high quality of meat and milk (OLIVEIRA et al, 2010) and meeting the nutritional needs of the animals.…”

“…However, the cakes and meals produced by the biodiesel industry, for example, have a high potential for use in the feeding of ruminants, considering their elevated protein and ethereal extract concentrations, which characterize them as high-protein, highenergy foods that can meet the nutritional needs of animals . Another byproduct, palm kernel meal (PKM), is obtained during the extraction of palm oil from Elaeis guineensis, through the use of pressure and organic solvents, and although the meal contains a high fraction of cell wall material (CARVALHO et al, 2006), PKM is still considered a high-energy and average-quality food for ruminants.…”

“…However, it is necessary to evaluate the feeding behavior of animals with the inclusion of these agroindustry byproducts, since the chemical and physical properties of these foods are different from those of fodder plants and may affect the degradation and transit of food in the gastrointestinal tract (CARVALHO et al, 2006). Through the observation of feeding duration and efficiency, the evaluation of feeding behavior enables us to better understand the digestion of foods TREVISAN et al, 2005), including utilization efficiency, absorption efficiency, and rumination conditions (MENDES NETO et al, 2007).…”

In order to evaluate the feeding behavior of sheep fed with diets containing different levels of palm kernel meal (PKM) substituted for corn silage, a metabolic assay was performed on 20 ewes (5 treatments × 4 replicates) over 25 d. The animals received corn silage diets with the addition of increasing levels of PKM (0, 15, 30, 45, and 60%). The following parameters were evaluated: dry matter (DM) intake, neutral detergent fiber (NDF) intake, feeding time, rumination time, idle time, number of merycism mastications per bolus, time spent ruminating each bolus, DM and NDF per bolus, number of ruminated boluses per day, feeding and rumination efficiency, total chewing time, and number of merycism mastications per day. The daily intake of both DM and NDF increased linearly (P < 0.05), and when sheep were fed diets of at least 43.18 and 39.15% PKM, respectively, the consumption values were significantly different than when sheep were fed diets with 0% PKM (P < 0.05). In contrast, feeding time declined linearly, and in response to diets with at least 28.05% PKM, the sheep exhibited significantly different feeding times from those of sheep fed 0% PKM, with a reduction of 0.0613 percentage points per 1% increase in PKM. Idle time, rumination time, and rumination time per bolus each exhibited quadratic responses (P < 0.05), and the minimum rumination time per bolus was 44.37 s with 35.19% PKM. A quadratic response was also observed for total chewing time and both measures of merycism mastications (P < 0.05). Therefore, we concluded that the inclusion of PKM in the diets of sheep improves some parameters of feeding behavior, and the use of PKM is recommended at DM percentages of up to 40%. ResumoPara avaliar o comportamento ingestivo de ovinos alimentados com dietas contendo diferentes níveis de farelo de dendê em substituição à silagem de milho, realizou-se ensaio metabólico, com 20 ovinos fêmeas, cinco tratamentos e quatro repetições, durante 25 dias. Os animais receberam dieta com silagem de milho (SM) e níveis crescentes de inclusão (0%, 15%, 30%, 45 e 60%) de farelo de dendê (FD). Foram avaliados o consumo de matéria seca (CMS) e de fibra detergente neutra (CFDN), tempo em alimentação (TAL), ruminação (TRU) e ócio (TOC), número de mastigações merícicas por bolo (NMM/ bolo), tempo despendido para ruminação de cada bolo (TR/bolo), gramas de MS e FDN por bolo, número de bolos ruminados por dia (NBR/dia), eficiências de ingestão e ruminação, em g MS/hora e g FDN/hora, tempo de mastigação total (TMT), em h/dia, e número de mastigações merícicas por dia (NMM/dia
