This study aimed to assess the bioeconomic performance of feedlot steers fed diets with high concentrate (80%) containing different levels of grounded grain of millet as a replacement for grounded corn grain. We used 89 European-zebu crossbred bulls, with initial average weight of 317.8±15.1kg and average initial age of two years, randomly assigned to diets with different levels of substitution of corn by millet (0, 33, 66 and 100%).The animals were allocated in 16 collective pens. The experimental design was a completely randomized design with four treatments and four replicates (pens). The nutrient intake, except neutral detergent fiber and non-fiber carbohydrates, did not differ between the diets tested (P>0.05). The average daily weight gain, body weight and final body codition score were not affected (P>0.05) by increasing the level of millet in the diet. The feed conversion increased 0.0048 kg of dry matter/kg of weight gain for each percentage point of millet in the diet. The total cost decreased linearly (P<0.05) with increasing the level of millet in the diet, reflecting the linear reduction in feed cost. As a result, the profit of finishing feedlot steers increased R$ 0.675 for each percentage point of millet in replacing corn. The millet can replace corn in diets with high concentrate for feedlot cattle, enabling reduction of production cost and increasing profits.

This study aimed to assess the carcass characteristics of European crossbred young bulls or Zebu feedlot finished with diets with high percentage of concentrate (80%) containing different levels of pearl millet grain as replacement for corn grain (0, 33, 66 and 100%). Forty-five young bulls with genotype predominance of Aberdeen Angus and forty-four young bulls with genotype predominance Nellore with average initial weight of 317.8 and 320.7 kg, respectively, and average age of 21 month, were allocated in 16 collective pens. At the end of the finishing period were slaughtered six animals of each genetic group, chosen according to the body weight and degree of finishing each treatment. The experimental design was the completely randomized design with treatments in a 4x2 factorial arrangement using six replicates. The replacement of corn grain by millet grain did not significantly influence slaughter weight (480.4 kg), hot carcass weight (259.5 kg), carcass yield (54.1%) and subcutaneous fat thickness (3.95 mm). Young bulls with genotype predominance of Aberdeen Angus showed significantly higher values for slaughter weight (507.6 vs. 453.3 kg), hot carcass weight (269.6 vs. 249.3 kg) and longissimus dorsi area (65.34 vs 56.83 cm2), however, were lower in carcass yield (53.2 vs. 55.0%). Millet grain can be used in substitution to corn grain for finishing steers since it does not change carcass traits of economic interest.

The objective of this work was to evaluate the fatty acid profile of crossbreed steers, in confinement, fed with diets containing increasing levels of ground millet grain in replacement to ground corn grain. Twenty-four European crossbred bulls and 24 Zebu crossbred bulls, slaughtered at 24 months of age, after 96 days in confinement, were used. The experimental design was completely randomized with treatments in a 4×2 factorial arrangement (four diets with 0, 33, 66, and 100% of pearl millet in the concentrate and two genetic groups) with six replicates. The increase in the levels of pearl millet grain in the diet increased linearly the participation of the arachidic (C20:0), heneicosanoic (C21:0), α-linolenic (C18:3 n-3), and dihomo-γ-linolenic (C20:3 n-6) fatty acids. European bulls showed meat with lower content of myristic (C14:0), heneicosanoic (C21:0), and γ-linolenic (C18:3 n-6) fatty acids than the Zebu bulls. The total concentration of saturated (45.2%), monounsaturated (41.2%), and polyunsaturated (8.7%) fatty acids, and the monounsaturated/saturated (1.09) and polyunsaturated/saturated (0.18) ratio were not affected by the genetic groups and diets. The increase in the percentage of millet grain in the diet of European and Zebu bulls improves the ratio between ω-6/ω-3 fatty acids.

This study aimed to evaluate the effects of including virginiamycin (VM) in two levels, the proteinenergy supplement for growing beef cattle diet with the tropical grass base in the dry season. Three treatments were evaluated: control treatment, only Mineral Supplement ME - Production - F.10 proteinenergy (SPE); 100 virginiamycin treatment (VM 100) + SPE 108 mg (Phigrow®) VM/animal/day and treatment virginiamycin 200 (200 MV) + SPE 216 mg (Phigrow®) VM/animal/day. The variables analyzed were the supplement intake (SI), average daily gain (ADG), biometric measurements and body condition score (BCS) in experiment 1 and the average daily supplement intake (ADSI), ruminal pH, ammonia nitrogen, in situ ruminal degradability of dry matter (DM), acid detergent fiber (ADF) and neutral detergent fiber (NDF) in experiment 2. There was no statistical difference for ADG, SI and biometric measurements (P>0.05), ADG for VM 200 of 0,431; VM 100 of 0.391 and control 0.398 kg/animal/day. There was no significant difference (P>0.05) for ruminal pH, the ammonia concentration and the variables at the in situ degradability of DM, NDF and ADF. The virginiamycin conveyed in SPE for beef cattle grazing can promote changes in consumption did not cause significant effects on the values of ruminal pH and ammonia nitrogen and do not show significant effects on the degradability of DM, NDF and ADF.

Cutaneous food allergy is an adverse immunological response, triggered by antigenic dietary components that may escape the digestion process and are absorbed intact through the gastrointestinal mucosa. In Brazil, there are only a few reports on cutaneous food allergy and antigenicity of food components used in pet food production. Thus, the aim of this report was to assess and describe data from medical records of canine patients diagnosed with cutaneous food allergy at a Veterinary Teaching Hospital from Jaboticabal, SP, Brazil, in order to evaluate epidemiological and clinical aspects related to this skin problem. From 2007 to 2012, 29 dogs received the diagnosis of cutaneous food allergy after an eight-week hypoallergenic elimination trial. Among them, purebred dogs were more frequent, as well as females, and their mean age was 50.4 months old. Pruritus was reported in all cases, especially in interdigital areas. In order to establish the diagnosis, most patients received home-cooked elimination diet, based on potato and lamb in approximately 80% of the cases. Besides, it was highlighted the importance of the hypoallergenic elimination diet being rigorously followed by dogs’ owners, aiming the adequate control of the clinical signs related to cutaneous food allergy. © 2014, Universidade Federal de Santa Maria.

The experiment was carried out at the Comigo Technology Center, in Rio Verde, State of Goiás, Brazil, with the objective of evaluating the effects of supplementation with calcium butyrate, as a growth promoting agent for the duodenal mucosa and Bacillus subtilis as a probiotic performance enhancer in feedlot cattle. Calcium butyrate (5 and 10 g per animal per day) and Bacillus (10 g per animal per day) were added to a basal diet. There were used 85 Nelore bulls, with average weight of 315 ± 7 kg. The experiment lasted 118 days, including the adaptation period, until slaughter at 30 months of age. Diets were distributed in a completely randomized design with four treatments, where: T1 = control (basal diet); T2 = basal diet + 5 g calcium butyrate; T3 = basal diet + 10 g calcium butyrate and T4 = basal diet + 10 g calcium butyrate + 10 g probiotic with four replications and five to six animals per replication. It was used a forage: concentrate ratio of 30:70, the roughage used was the corn silage. Height and width measurements of intestinal villi were taken, and carcass and meat quality were evaluated. The supplementation of calcium butyrate and Bacillus subtilis positively influenced (p < 0.05) the carcass marbling level and calcium butyrate increased the villus height in the small intestine. © 2016, Eduem - Editora da Universidade Estadual de Maringa.

This study was carried out to evaluate the effects of pequi peel flour (PPF) in the diet of laying Japanese quails on their productive performance and on the quality and cost of the eggs produced. A total of 160 quail (Coturnix coturnix japonica) were distributed in a completely randomized design with four treatments and five replicates with eight birds each. Treatments consisted of different levels of PPF (0, 1, 2 and 3%) in a commercial diet based on sorghum. Evaluated parameters were productive performance (daily feed intake, laying rate, egg weight, egg mass and feed conversion rate), egg quality (yolk, albumen and eggshell weight and measures, yolk colour, ash and calcium content of eggshell, specific weight, Haugh unit, and nutrient content of the egg) and average cost of the production. PPF did not affect (p > 0.05) productive performance and nutritional composition, quality or average cost of the eggs; however, yolk colour was linearly increased (p < 0.05) with the PPF levels in the diets. It was concluded that PPF might be included in the commercial diets of Japanese quails up to 3% due to the improvement in yolk colour. © 2016, Eduem - Editora da Universidade Estadual de Maringa.

Anacardium othonianum Rizz. is a medicinal plant species that is native to the Brazilian savannah. Adult plants are different from other genus members in this ecosystem due to their size, and efforts to locate the plants may lead to their extraction from the savannah and, frequently, plant death. Micropropagation has played a significant role in the propagation and preservation of specimens of several plant species; therefore, this study evaluated the effect of various salt concentrations and culture medium volumes on the in vitro cultivation of A. othonianum Rizz. Trial (I) evaluated two culture media (MS and WPM) and three salt concentrations (100, 50and 25%) in a completely randomized design. Trial (II) evaluated two culture media and salt concentrations, MS(50%) and WPM (100%), and five medium volumes (10, 15, 20, 25 and 30 mL per test tube) as a 2 × 5 factorial in a completely randomized design. After 30 and 60 days of growth, the percentage of plantlet survival, average plantlet and leaf lengths and the average number of leaves and buds per explant were evaluated. The MS (50 and 25%) media and WPM (100 and 50%) media were the most effective for plantlet regeneration. The best responses were observed in 15- and 25-mL volumes of the MS (50%) medium. Therefore, the use of a 15-mL volume is suggested for greater medium economy.
