| Purebred and crossbred calves (n = 3,871) were selected that were born in the sub-region of the Pantanal of Aquidauana (Brazil), derived from Nellore, Brangus, Wagyu, and ½ Brangus + ½ Nellore cows, which were artificially inseminated by bulls of the Aberdeen Angus, Red Angus, Brangus, Nellore, and Wagyubreeds. Parameters such as weaning weight, daily gain from birth to weaning, and the number of days to gain 160 kg, were assessed inthese calves and phenotypic correlations between the traits were evaluated. Data were analyzed using two statistical models. The first model included sire breed effects, the genetic group of the cow, sex, year of birth (AN), birth season (EN), and the interaction AN * EN. The second model included the genetic group of the calf,... |

| The objective of this study was to evaluate the correlations existing between nutrient intake and ingestive behavior of crossbred steers in the post-weaning phase on Brachiaria brizantha cv. Marandu, during the rainy period. Twenty-two steers were distributed into a completely randomized design, with two types of supplement and eleven replications, managed under rotational grazing, in a 6.5 ha area. Pearson’s Linear Correlation analysis was performed between the behavior variables and the performance variables values. The correlation coefficients were tested by the t test. The average daily gain (ADG) showed positive correlation with the times spent ruminating and eating at the trough and total chewing time. Positive correlation was observed between the... |

| Performance, carcass, non-carcass and commercial cuts and components of Texel × Santa Inês crossbred lambs, managed in confinement and fed diets based on soybean oil, soybeans and a conventional diet, with or without the use of monensin (78 ppm dry matter basis) were evaluated. Thirty-six Texel × Santa Inês lambs (18 males and 18 females) were managed in intensive systems. Animals were slaughtered after 87 days of confinement, and performance, carcass characteristics, weight and percentages of carcass and non-carcass components were evaluated. The animals fed the control diet had heavier carcass and parts than animals fed soybean, while the oil diet did not differ from the controls in most parameters. The animals fed soybean showed lower intake kg dry... |

| In order to evaluate the use of oilseeds in the diet of goat kids, two experiments were performed. Experimental treatments consisted of four different total mixed diets, all containing oat hay, ground corn, soybean meal and mineral supplement, and differing in oilseeds inclusion (dry matter basis), according to the treatments: 1) control (without oilseeds), 2) diet containing 7.87% flaxseed, 3) diet with 7.30% sunflower seed, and 4) diet containing 8.00% canola. In the first experiment (to evaluate the performance), 28 ¾ Boer + ¼ Saanen castrated goat kids (22.66 kg to 30.88 kg BW) were allotted in a randomized design in feedlot. There was no difference between treatments for intake of dry matter, organic matter, crude protein and ether extract, total... |
