This study compared the dry matter intake (DMI) of Nellore heifers and bulls in the feedlot, predicted by the BR-Corte (2010 and 2016) and NRC (2000) nutritional systems. Hence, two experiments were conducted in a completely randomized design. The first one used 47 Nellore bulls, not castrated, with an average initial weight of 413 kg, and 19 months of age. The second experiment used 24 Nellore heifers with an average initial weight of 300 kg and 23 months of age. The accuracy and approximation of the DMI estimates by the nutritional systems were adjusted with the simple linear regression model and the root mean square error of prediction (RMSEP). The DMI was 8.06 kg day-1 for Nellore heifers and 11.54 kg day-1 for bulls, which are higher than the values ​​ predicted by the nutritional systems. The NRC (2000) and BR-Corte (2010 and 2016) underestimated DMI in 20.84, 20.09, and 19.35% for heifers and 28.07, 16.20, and 11.78% for bulls, respectively. It was concluded that the BR-Corte 2010 and 2016 were the most suitable models to estimate the DMI of Nellore heifers and bulls for higher precision and accuracy.

The objective was to compare the dry matter consumption (CMS) observed, through the use of the GrowSafe® electronic system, with that predicted by the BR-Corte (2010 and 2016) and NRC (2000) nutritional systems in confined Senepol bulls. To this end, 24 Senepol Bulls were used in a completely randomized design, uncastrated with an average initial weight of 368 kg and 16 months of age. The evaluation of the accuracy and approximation of the CMS estimates by the nutritional systems was adjusted by the simple linear regression model and the decomposition of the mean square of the prediction error (QMEP). The mean CMS observed was 10.33 kg.day-1, higher than the values predicted by the nutritional systems, in which the values predicted by the NRC (2000) and BR-Corte 2010 and 2016 underestimated the CMS by 29.62, 6.19 and 2.03%, respectively. The verification of QMEP and its decomposition made it possible to infer the proximity of the values predicted by the BR-Corte 2010 and 2016 models and the values observed, which presented a better adjustment in relation to the NRC. Surprisingly the values predicted by the NRC, created from a database with Bos taurus animals, showed greater distance from the values predicted and observed, and it was expected greater accuracy of the NRC models for this category and animal breed. It is concluded that the BR-Corte 2016 was the most appropriate model to estimate the CMS of confined Senepol bulls.

Industrialization of the Babassu coconut for edible oil production generates many co-products and has great potential to be used in ruminant nutrition. The aim of this study was to evaluate the effect of different inclusions of endocarp meal type II of Babassu coconut (BEMII) on intake and digestibility of sheep diets. Twenty non-castrated male sheep with an undefined breed were distributed in a completely randomized design with four treatments and five replications. The animals received an experimental diet with increasing inclusions of BEMII (0.0%, 7.5%, 15.0%, and 22.5%). Increasing additions of the coproduct negatively influenced dry matter intake (g/BW and g/kg0.75). Crude protein intake (in grams) per day decreased linearly with the inclusion of BEMII, presenting a reduction of 49.35 g/d. The inclusion of 7.5% showed the best response for energy balance among all inclusions and presented the closest nitrogen balance value when compared to the control group; therefore, this inclusion percentage is the best for endocarp meal utilization.

This study was conducted to investigate the effects of feeding varying levels of Cochlospermum planchonii using 25 WAD goats. The study lasted for 84 days during which feed intake and haematological and biochemical parameters were monitored in 25 goats using a completely randomized design. Five diets consisting of pulverized Cochlospermum planchonii rhizome at varying proportions of 0 %. 5 %, 10 %, 20 % and 40 % respectively and designated as T1, T2, T3, T4 and T5 were compounded with other feed ingredients. Goats were offered concentrate and Gamba grass (Andropogon gayanus) at 08:30 am. The results obtained revealed that there was no significant difference in dry matter intake of forage but the amount of concentrate consumed by T5 was significantly (P < 0.05) lower than the other treatments. Haematological parameters such as; PCV, Hb, RBC, MCV, MCH, MCHC, WBC, neutrophils, lymphocytes and eosinophils did not differ across the treatments, while biochemical parameters such as; total protein, albumin, globulin, glucose, creatinine, urea and ALT were also similar across the treatments, however, cholesterol, AST and ALP were significantly different (P < 0.05). The study revealed that inclusion of Cochlospermum planchonii in the diets of WAD goats had no adverse effects on the haematological and serum biochemical parameters. Therefore, dietary inclusion or drenching with the plant is safe especially at 20 % inclusion.

Ingestive Behaviour

Voluntary consumption (VolC) and ingestive behaviour (IB) of lambs fed diets containing different percentages (0.0; 7.5; 15.0 and 22.5%) of babassu mesocarp bran (I-BMB) were evaluated. The trial was at the Federal University of Tocantins, Campus de Araguaína-TO. Twenty lambs were evaluated using a completely randomized design, and five replications were performed. VolC data was obtained by measuring total volumes of both food supplied and food remaining after feeding. IB was evaluated throughout two, non-consecutive 24-h periods, with observations were recorded every five minutes that described the following behavioural variables: resting (REST), rumination (RUM), intake (INT) and chewing (CHEW). The particle size was also measured using a Penn State particle separator. All VolC parameters (dry matter intake, DMI; crude protein intake, CPI; neutral detergent fibre intake, NDFI; and acid detergent fibre intake, ADFI) increased linearly with I-BMB intake. I-BMB consumption did not interfere with water intake, nor did it affect I-BMB did not affect the duration of DMI, NDFI and ADFI. However, linear increases of rumination and chewing activities associated with DMI, NDFI and ADFI were observed as I-BMB levels increased. In summary, effects of inclusion I-BMB in diets of lambs included increased voluntary consumption, and reduced rumination and chewing, but not ingestion, efficiency. When economically favorable, these data suggest that inclusion of up to 22.5% I-BMB within balanced diets should be applied.

This study aimed to verify the effects of supplying different energy patterns on ingestive behavior of feedlot-finished cattle. Twenty-seven pure and crossbred Charolais or Nellore steers with an initial average age and weight of 22 months and 252.8 kg, respectively, were used. Three treatments were carried out, two of them with an increasing rate of concentrate in the diet during the finishing period (IT5 and IT10) and one with constant roughage to concentrate ratio (CT). The experimental design was a completely randomized design with three treatments, five periods, and nine replications. Feeding time was higher for CT (4.31 hours) when compared to IT5 (3.85 hours). Steers from the treatment IT10 remained longer in lying leisure (8.14 hours) when compared to the treatment CT (7.24 hours). A superiority of chewing per ruminated bolus was observed in IT10 (58.59 seconds) when compared to IT5 (54.11 seconds) whereas a higher number of ruminated bolus was observed in TC5 (534.68 ruminated bolus day?1) when compared to IT10 (473.77 ruminated bolus day?1). Animals from CT presented a higher dry matter intake (9.54 kg day?1) than those from IT10 (8.63 kg day?1). Steers from CT and IT5 showed a higher NDF intake (3.63 and 3.58 kg NDF day?1, respectively) when compared to IT10 (3.29 kg NDF day?1). The constant energy pattern increases feeding time and dry matter intake. The one of less vigorous growth increases the number of bolus ruminated per day, while the one of more vigorous growth increases idle time and chews per bolus and decreases the intake of neutral detergent fiber.

ABSTRACT Cowpea is broadly cultivated worldwide, especially in semi-arid or arid regions where soil or irrigation water salt contents can negatively influence the species’ productive capacity. The objective of this study was to evaluate the morphophysiological responses of cowpea genotypes to irrigation water salinity. The experiment was conducted in a greenhouse, under a completely randomized design with nine replications and in a 5x3 factorial scheme. Treatments consisted of five levels of irrigation water electrical conductivity - EC (EC0: 0.55; EC1: 1.60; EC2: 3.20; EC3: 4.80 and EC4: 6.40 dS m-1), applied from the 15th day after sowing (DAS), and three cowpea genotypes (G1: BRS Imponente; G2: MNC04-795F-168 and G3: MNC04-795F-159). EC increases at 35 DAS promoted stem diameter reductions of 8.0% (G1), 11.4% (G2), and 7.7% (G3), indicating different resistance to salinity by each genotype. Leaf area reductions at 25 and 38 DAS were 30.9% and 38.8% for EC0 and EC4, respectively. The BRS Imponente cultivar presented a performance superior to those of G2 and G3 in relation to stem diameter and stem dry matter at 25 DAS, and root-shoot and root-leaf ratios at 38 DAS.
