The effects of different ratios of sugarcane and elephant grass (0:100, 25:75, 50:50, 75:25 and 100:0% of the natural basis) were assessed on the chemical composition and losses in silages treated with a bacterial inoculant, using laboratory silos. A 2 × 5 factorial arrangement (with and without inoculant and five elephant grass ratios) in a randomized blocks design with three replications was used. Interaction was observed in the sugarcane and elephant grass ratio × bacterial inoculant for crude protein (CP) […]

An experiment was conducted with the objective of evaluating the effects of different levels of benzoic acid (Vevovitall) on the performance and intestinal morphology of the duodenum in piglets from 28 to 70 days of age. One hundred and sixty Dalland × Penarlan piglets weaned at 21 day old, separated by sex, were used. The experiment was divided into pre-initial 1 (28 to 35 days), pre-initial 2 (36 to 46 days) and initial (47 to 70 days) phases. A randomized […]

The objective of this study was to evaluate the effects of chemical additives on the fermentative dynamics and chemical composition of sugarcane silages. The experiment was conducted in a randomized complete design with five replications. Sugarcane was ensiled without additives or with calcium oxide and limestone (1% as-fed basis) constituing three treatments. The fermentative dynamic was analyzed based on gas losses, organic acids and ethanol production and, silages chemical composition. The calcium oxide and limestone treatments showed the lowest values […]

An efficient digestion and nutrients absorption, coupled with good animal health status, are fundamental needs in the competitive animal protein industry. Poor absorption of nutrients cause economic losses, and are a source of imbalance in the microbial intestinal microflora, opening doors to diarrhea and other intestinal diseases, or even facilitating systemic problems of animal health. These problems become even more critical in the current scenario of increased risk with the progressive restriction of the use of antibiotic growth promoters around […]

This study aimed to evaluate the effect of intraruminal infusion of propionic acid (RPA) associated to two (80:20 and 60:40) forage:concentrate ratios (FCR), for young bulls. Four Holstein × Zebu crossbred young bulls with average age of 7 months and 160 kg of body weight (BW) were distributed to a 4 × 4 Latin square design. A total mixed ration, isonitrogenous diets, was ad libitum fed to animals. The propionic acid was obtained by fermentation of reconstituted milk whey by […]

To evaluate the effects of the dietary supplementation of maltodextrin in partial replacement of lactose and acidifiers on performance, digestibility and economical viability of weanling pigs, 144 Dalland piglets with initial weights of 6.0 ± 0.45 kg were used in trial 1, where more complex diets were used, and 5.8 ± 0.53 kg in trial 2. A completely randomized block design in a 2 × 2 factorial arrangement was used for the treatments (absence or presence of maltodextrin ´ absence […]

This study was carried out to evaluate the effect of the supplementation of organic acids in the diets and ortho-phosphoric acid in the drinking water on broiler performance. A total of 2,112 broiler chicks was allotted to six treatments, each one with eight replications. The diets, all vegetable, were composed by corn-soybean meal without antibiotic growth promoters or anticoccidials. A control diet did not have organic acids, whereas the other treatments had supplementation of organic acid blends as follow for […]

The objectives of this trial were to evaluate the effects of regrowth age of elephantgrass (Pennisetum purpureum Schum. cv. Napier), and citrus pulp addition on the fermentation pattern and aerobic stability of their silage. In addition to that, this research also aimed to create a recommendation index of citrus pulp addition taking into account the moisture concentration of the grass, in order to decrease costs of technology adoption. Laboratory silos (6 L-capacity each) were used and 20 treatments were tested, […]

The experiment was carried out to evaluate the fermentative and microbiological dynamics of the tropical grass silages using pelleted citrus pulp (PCP) as an additive. The Tanzania (Panicum maximum cv. Tanzania) and Marandu (Brachiaria brizantha (Hochst. ex. A. RICH) Stapf cv. Marandu) grasses were harvested at 64 and 49 days of regrowth, respectively. The following treatments were evaluated: control (0%), addition of 5% and 10% of pelleted citrus pulp (PCP) in a fresh matter basis, and seven fermentation periods (1, […]

The effects of increasing levels of citrus pulp on fermentation pattern and nutritive value of elephantgrass silage was evaluated. Elephantgrass harvested at 90 days was ensiled with increasing levels of dried citrus pulp: 0, 2.5, 5, 7.5, 10, 12.5 and 15% (fresh matter basis). Silages were produced in 28 plastic experimental silos (4 replicates/treatment) bearing Bunsen valves. Silos were opened 106 days after ensiling, when samples were taken for the analysis of silages organic acids and chemical components. Silage dry […]
