Desempenho e qualidade da carne de bovinos Nelore e F1 Brangus × Nelore recebendo suplemento com cromo complexado à molécula orgânica na terminação a pasto

Objetivou-se avaliar o efeito da suplementação com cromo complexado à molécula orgânica do suplemento no desempenho produtivo, nas características de carcaça e na qualidade da carne de bovinos terminados em regime de pastagem. Foram utilizados 18 bovinos Nelore e 18 F1 Brangus × Nelore castrados, com 16 meses de idade, mantidos com suplementação mineral protéica, com ou sem cromo complexado à molécula orgânica e abatidos aos 22 meses de idade. O ganho médio diário de peso vivo (GMD) não diferiu entre grupos genéticos, entretanto animais mantidos com suplemento contendo cromo apresentaram maior GMD (494 g) em comparação aos demais (420 g). A adição de cromo orgânico no suplemento não promoveu alterações na área de olho-de-lombo (63,42 cm²) e na espessura de gordura subcutânea do dorso (5,46 mm) e da garupa (5,58 mm), tomados por meio do ultra-som. O peso médio de carcaça quente foi 235 kg e o rendimento médio de carcaça quente, 52,09%, com superioridade do suplemento contendo cromo (238 kg e 52,9%) em relação ao controle (231 kg e 51,2%). Animais Nelore e F1 Brangus × Nelore apresentam potencial similar de produção de carne a pasto. A suplementação mineral protéica com adição de cromo complexado à molécula orgânica aumenta o ganho de peso e o rendimento de carcaça, mas não influencia os parâmetros qualitativos da carne.

Utilização de NaCl no suplemento como alternativa para viabilizar o sistema de alimentação de bezerros em creep-feeding

Thirty two Canchim suckling calves, maintained on rotational grazing system of Brachiaria brizantha cv. Marandu, were divided in three groups corresponding to three evaluated treatments: control (without creep-feeding); SAL5 (addition of 5% of NaCl to concentrate fed in creep-feeding); and SAL10 (addition of 10% of NaCl to concentrate fed in creep-feeding). Feeding in a creep-feeding system lasted 90 days, divided in three subperiods of 30 days. The body weight gain was greater in the subperiods 1 and 2 for SAL10 and SAL5 treatments, respectively. There were no differences in the third subperiod and, in the overall period, the SAL10 treatment (0.91 kg.animal-1.day-1) was better than control treatment (0.81 kg,animal-1.day-1). The monthly remuneration provided by the treatments SAL5 e SAL10 related to the control group were-12.5 and 6.0%, respectively. The body weight differentials at weaning, compared to the control group, for creep-feeding provide a monthly net profit of 0, 0.6, 1.2, and 6.0% should be 10.8, 11.0, 11.2, and 12.8 kg.animal-1 for SAL5 and 7.6, 7.7, 7.8, and 9.0 kg.animal-1 for SAL10. It was concluded that the limited supplement intake in creep-feeding was necessary to obtain economic viability.

Desenvolvimento de núcleos de Apis mellifera alimentados com suplemento aminoácido vitamínico, Promotor L

The development in the area of creates was studied of 14 nuclei with four mass off cells from the division of nine beehives of africanized Apis mellifera honeybees, distributed in two treatments: TPL - nuclei fed with inverted sugar + 3.5ml of the vitaminic amino acid supplement (Promotor L® ), composition for six nuclei and TAI - nuclei fed with composed inverted sugar for eight nuclei. The nuclei had been fed weekly in individual feeder's type tray, and the evaluations carried through in four periods, totalizing 74 days. The treatments had not presented significant difference, being that, number the TPL presented area of creates inferior to TAI (233.63 versus. 273.02cm 2, respectively). How much to the periods the four was superior (P<0.05) to the first and as second, being that the third did not present significant difference (P<0.05) in relation to the others. The use of the TAI was economically more favorable in relation to the TPL in R$0.21 in relation to the cost for production of 1kg of food.

Fração de excreção de sódio, osmolaridade e densidade urinária em recém-nascidos prematuros alimentados com leite humano de banco adicionado de suplemento

Objective: This research was performed with the objective of investigating the renal effects on premature newborn infants of fortifying banked donor human milk. Methods: Clinical intervention trial, of the before-and-after type, involving 28 premature newborn infants split into two groups by postconceptional age at the start of the study: GI < 34 weeks (n = 14) and GII ≥ 34 weeks (n = 14), and assessed at three sample points: S1, on unfortified donor human milk, S2, after 3 days, and S3, after 10-13 days on fortified donor human milk. Nutrient intake, weight gain, fractional sodium excretion, urinary osmolality and specific density were compared with two-way ANOVA for repeated measures. Results: Fluids, energy and sodium intakes were similar for both groups, and weight gain was satisfactory. Among the preterms with < 34 weeks postconceptional age, serum sodium was lower at the end of the study and the fractional sodium excretion was elevated at the start and at the end of the study (S1 = 2.11±1.05; S2 = 1.25±0.64; S3 = 1.62±0.88), with a significant difference in relation to GII (S1 = 1.34±0.94; S2 = 0.90±0.54; S3 = 0.91±0.82). Osmolality and urinary specific density were normal, with no differences between groups or collection dates. Conclusions: No adverse effects on the renal function of these preterms were detected as a result of being fed fortified donor human milk. Copyright © 2006 by Sociedade Brasileira de Pediatria.

Comportamento ingestivo de novilhas Nelore em pastejo recebendo suplemento a base de própolis ou monensina sódica

We evaluated the effect of additives the basis of propolis and monensin on ingestive behavior (grazing -GRA, rumination lying -RLY, rumination in foot -RFO, rumination -RUM; idleness lying -ILY, idleness in standing -IDS, idleness -IDL, walking -WAL, posture standing -POS, posture lying -PLY, intake of supplement and water -ISW) of heifers in Tifton 85 grazing. The treatments were: no additive (NAD); propolis - PRO (33.24 mg animal-1 of total flavonoid in apigenin), and monensin -MON (100 mg animal(-1)). Were used five heifers treatment(-1) for evaluation of ingestive behavior during 12 hours of total valuation, which was divided into three periods. Used a factorial design into 3 x 3 for evaluation of ingestive behavior as a function of the evaluation periods. Were utilized three paddocks of 2.9 acres of grass Tifton 85. The additives and mineral supplement (50 g animal(-1)) were provided with 200 g of corn meal to 17 hours. For all activities of the ingestive behaviors observed the effect of period on the time spent on of different activities. The activities of GRA and ISW were higher in the third period (15hours to 19hours) compared to the first period (7hours at 11hours). For IDL and PLY, there was a higher time in minutes for heifers treatment with PRO in the period of 7hours at 11hours, compared to other treatments (NAD and MON). Thus, it is concluded that the use of the additive based on propolis enables sodium monensin replacement, to heifers maintained on pasture without changing eating behavior as well as providing greater idleness during the day the without affecting animal performance.
