“…The direct correlation between feeding and the ingestion of cell wall justifies the small differences in average forage NDF (643.57 g kg -1 of dry matter [DM]) and average forage DM between treatments (Table 1) (Carlotto et al, 2010). It is of note that a study found that concentrate intake was negatively correlated with rumination time (Pizzuti et al, 2012;Santana et al, 2012), and the latter was not correlated with weight gain and feed conversion (Santana et al, 2013). The time spent ruminating and at each feeding station (385 and 42 min day -1 , respectively) were not affected by the level of The decrease in grazing time did not affect average daily weight gain because steers consumed less forage but more concentrate (Goes et al, 2010;Sales et al, 2011;Benatti et al, 2012).…”

The present study was developed at the Beef Cattle Laboratory of the Federal University of Santa Maria and evaluated the effect of three levels of concentrate supplementation (S 0.8, S 1.0, and S 1.2, corresponding to 0.8%, 1.0%, and 1.2% of bodyweight, respectively) on the ingestive behavior and movement patterns of 24 steers grazing on sorghum. The experiments were performed using a completely randomized block design in a 3 ? 3 factorial arrangement (three levels of supplementation ?three experimental periods), and the grazing time was evaluated using a 3 ? 24 factorial arrangement (three levels of supplementation ? 24 hours of observation). The steers fed S 0.8 presented longer(P=0.009) grazing time in the morning (241 min day-1) compared to animals fed S 1.2(172 min day-1). The number of bites per feeding station was higher (4.05) during the second experimental period, and the number of bites min-1 increased from 25.4 to 31.4 from the first to the second experimental period. The changes in sward structure during the growth stages of sorghum affected the number of bites per feeding station and the number of bites per minute.

“…Digestibility can be influenced by several factors such as the com-justment of animal feeding management to obtain better productive performance. However, associations between behavioral and metabolic variables have been found in research discussions, most of the times without the proper scientific basis for these correlations (Santana Júnior et al, 2012).…”

Objetivou-se avaliar as correlações lineares do comportamento ingestivo e a digestibilidade aparente em borregos confinados. Foram utilizados 50 ovinos machos, castrados, da raça Santa Inês, com peso corporal médio de 20 ± 4,38 kg e quatro meses de idade. Os animais receberam níveis de oferta de dieta com o objetivo de promover variações no consumo alimentar e digestibilidade aparente. Foram mensurados a digestibilidade e o comportamento ingestivo dos animais. As análises foram realizadas usando correlações lineares de Pearson utilizando o teste t, a 5% de probabilidade. Verificou-se correlação positiva do tempo de alimentação e a digestibilidade aparente de extrato etéreo e os nutrientes digestíveis totais (NDT) (p

The objective of this study was to evaluate the effect of increasing the supply of protein with different degradation rates on the performance and metabolism of growing Nellore cattle reared on Brachiaria brizantha cv. Marandu pasture during the transition period from the dry to rainy season. The experiment was installed on an area of 34 ha, divided into 12 paddocks with an average area of 2.85 ha. In the performance evaluation were utilized 72 recently weaned, non-castrated Nellore cattle with an initial body weight (BW) of 199 kg (SEM = 16). The following supplements were used: energy protein supplement containing 25% crude protein (CP) (C-25) and energy protein supplements containing 40% CP with one third highly degradable CP and two thirds poorly degradable CP (40-1/3NPN), one half highly degradable CP and one half poorly degradable CP (40-1/2NPN), and two thirds highly degradable CP and one third poorly degradable CP (40-2/3NPN). Higher protein degradation rates reduced supplement intake (P < 0.01). In the first period, animals consuming supplement 40-1/3NPN exhibited higher average daily gain (ADG) (0.30 kg/day), similar to that of animals receiving supplement 40-1/2NPN (P = 0.04). In the second period, supplement 40-2/3NPN resulted in lower ADG (0.19 kg/day less than the other supplements). There was no effect of supplement on animal performance in the third period (P > 0.10), when ADG was 0.56 kg/day. In conclusion, the response to supplementation is associated with interactions with characteristics of the forage canopy. Supplementation with a true protein source will be beneficial only during the early stage of the dry-rainy season transition period.
