“…In addition, the DM and total DM intakes were 0.39 and 0.89 kg/d, respectively, lower than those observed by Gomes et al (2012), who evaluated the inclusion of soybean hulls in the diet of male calves during the preweaning period and found a mean DM intake from concentrate feed of 0.49 kg/d. However, despite the lower intakes, the feed conversion results were better, and the animals needed to consume 1.70 kg of total DM to gain one kilogram of live weight, whereas in the study by Gomes et al (2012), the animals needed 1.91 kg/d. This shows that the animals were highly efficient, which impacted their weight gain as evidenced by their ADG of 0.56 kg/d.…”

The objective of this study was to assess the effects of two levels of soybean hulls (0 and 400.1 g/kg) and whole or ground corn in the diet of newborn crossbred dairy male calves on intake, performance, blood indicators, and feeding cost. Twenty-eight calves with an average weight of 33.0±6.2 kg and four days of age were distributed into four treatment groups in a completely randomized design (n = 7) for 56 days. Weekly samples of feed, diets, and leftovers were collected to determine dry matter and nutrient intakes. To evaluate apparent digestibility, samples were taken using titanium dioxide as a maker. Blood samples were also collected to evaluate blood indicators. The inclusion of soybean hulls resulted in greater neutral detergent fiber intake by the calves, but reduced their non-fibrous carbohydrates intake, which was also reduced by the use of whole corn in the diet. Although the total digestible nutrients content of diets decreased with the use of whole corn and inclusion of soybean hulls, its intake did not vary (0.75 kg/d), regardless of the factors analyzed. The apparent digestibilities of dry matter (0.87 kg/kg) and crude protein (0.89 kg/kg) were similar, resulting in similar performance between the animals, regardless of the factors analyzed. In the quantities evaluated, the use of soybean hulls or whole corn did not affect blood indicators and was insufficient to reduce feed costs; the cost of daily feed was $2.06, while the cost per kilogram of gain was $3.74. The inclusion of up to 400.1 g/kg of soybean hulls or the replacement of ground corn with whole corn does not affect the performance of crossbred dairy calves during the preweaning period, demonstrating that both can be used in animal feed during this phase of production.

“…Rump height (RH) and height at the withers (HW) were not affected (P > 0.05) by the substitution of GC by SH, averaging 138.99 and 133.62 cm, respectively (Table 4). Gomes et al (2012) described similar results in an experiment investigating the inclusion of SH levels (0, 15, 30, and 45%) replacing corn in calf diets. In their study, no alterations were found in HW or RH, which reflects the similar ADG observed across treatments.…”

We examined the production performance of Nellore heifers fed high-concentrate (90%) diets in which ground corn (GC) was substituted by ground soybean hulls (SH) at increasing levels (0, 33, 66, and 100%), in the concentrate portion. A total of 144 heifers (263.40 ± 13.90 kg average initial weight; 27 months old) received the test diets in a feedlot for 112 days. The experiment was set up as a completely randomised design with four treatments. Data were subjected to ANOVA and orthogonal contrasts, adopting ? = 5%. The sum of squares of treatments in the contrast analysis was decomposed into two orthogonal contrasts (L - linear and Q - quadratic effect) for the level of SH substituting GC. Dry matter intake was not changed by the GC substitution levels, averaging 2.51% of body weight. There was a linear increase in neutral detergent fibre intake (1.08, 2.03, 2.92, 3.78, 4.85 kg/day) and feed conversion (6.20, 7.08, 7.77, and 8.67 kg/kg); and a linear decrease in total digestible nutrient intake (5.78, 5.16, 5.03, 5.12, and 3.66 kg/day), average daily gain (1.24, 1.11, 1.02, and 0.89 kg/day), and slaughter weight (383.52, 374.71, 363.25, and 366.27 kg) as the substitution level was increased (0, 33, 66, and 100%, respectively). Subcutaneous fat thickness and loin-eye area were not influenced (P > 0.05), averaging 5.30 mm and 53.09 cm2, respectively. Substituting ground corn by ground soybean hulls in high-concentrate diets determined a reduction in production performance of feedlot-finished Nellore heifers.

“…These results were lower than those observed in the work of [24], which evaluated the inclusion of soybean hulls in the diet of calves during the breeding phase and found a mean DMI of concentrated feed of 0.49 kg/d. However, despite the lower consumption values, the feed conversion results were better, and the animals needed to consume 1.70 kg of TDM to gain one kilogram live weight, whereas in the work by [31], the animals needed 1.91 kg/d, showing that the animals were highly efficient, what corresponded to a reflex in the weight gain, since the animals presented ADG of 0.56 kg/d.…”

24This work evaluated the use of soybean hulls and whole or ground corn in the diets of 25 suckling calves. Diets containing two levels of soybean hull inclusion (0 and 400.1 g/kg) and 26 corn in different physical forms (whole or ground) were evaluated in the diets of newborn 27 crossbred dairy calves that were housed and received experimental diets plus four liters of 28 milk per day over 56 days. Weekly samples of food, diets and leftovers were taken to 29 determine dry matter and nutrient intake. To evaluate the apparent digestibility, samples were 30 taken from the diets, leftovers and feces for three consecutive days using titanium dioxide as 31 an indicator. Blood samples were also collected to evaluate the blood indicators. Including 32 soybean hulls in the diet increased the consumption of neutral detergent fiber but reduced the 33 consumption of non-fibrous carbohydrates, which was also reduced by using whole corn in 34 the diet. Total digestible nutrient consumption did not vary, although its value was reduced by 35 using whole corn and including soybean hulls. The apparent digestibilities of the dry matter 36 and crude protein were similar, resulting in similar performances between the animals, 37 regardless of the factors analyzed. Using soybean hulls or whole corn did not affect blood 38 indicators or feeding costs. Soybean hull or whole corn usage did not affect the performance 39 of crossbred dairy calves during rearing. 41 Although milk producers are efficient at producing heifers, male cattle production is 42 typically neglected. In Brazil, the number of cows milked corresponds to 23 million animals 43 [1] with a birth rate of 50% male; thus, 11.5 million calves are produced annually. Although 44 no official data exist on the number of calves slaughtered shortly after birth in Brazil, 45 approximately 40% of these calves are slaughtered in their first days of life, representing 46 approximately 4.6 million calves. This occurs because producers consider that these calves 47 will increase their production costs without favorable financial returns; however, these 48 animals can yield good productive results when their nutritional and hygiene requirements are 49 fulfilled [2], mainly during the first days of the animal's life (0 to 60 days). 50This period is the most costly in the production system; thus, solutions are needed to 51 balance these costs, such as using palatable solid foods, which stimulate the animals to eat. 52This allows the animals' weaning age to be reduced because they benefit from more efficient 53 use of the nutrients in solid food [3,4], which reduces the problems caused by weaning the 54 animals early [5][6][7], increases the amount of milk available for sale and reduces the demand 55 for labor. 56However, the use of feedstuff, such as corn and soybeans meal, which are traditionally 57 used in animal feed, in the biofuel production, has increased the price of these inputs [8]. 58Thus, alternatives to these foods are needed to reduce feed costs, such as by-produ...
