In the last two decades breeders have focused on hybridization within the grass genus Brachiaria in order to integrate the most outstanding characteristics of several species to enhance animal performance in forage-livestock system, especially when addressing edaphoclimatic conditions and pest susceptibility. The objective of this study was to compare herbage accumulation, nutritive value, and animal performance of ?Ipyporã? [B. ruziziensis Germ. & Evrard × B. brizantha (Hochst. ex A. Rich.) Stapf] and ?Mulato II? (B. ruziziensis × B. brizantha× B. decumbens Stapf) brachiariagrasses in the Brazilian Amazon biome. All experimental units were continuously stocked using a variable stocking rate from May 2016 to May 2018. Herbage accumulation (HA) was greater in Mulato II (17,370 kg DM ha?1) than Ipyporã (14,930 kg DM ha?1), resulting in 25 and 23% greater stocking rate (SR) and gain ha?1 than Ipyporã, respectively. Herbage allowance did not differ between grasses (averaging 6.52 kg DM kg?1 BW). The crude protein (CP), neutral (NDF), and acid (ADF) detergent fiber concentrations did not differ between cultivars (P > 0.05). Greater annual HA and gain ha-1 for Mulato II support its use in intensive forage-based systems. However, susceptibility of Mulato II to spittlebug requires regular monitoring and treatment in regions like the Amazon biome, where risk of spittlebug damage is great. In contrast, spittlebug-resistant Ipyporã can provide excellent plant and animal response with no spittlebug risk, offering a sustainable alternative to Mulato II for forage diversification.

Abstract: The aim of this study was to determine the median lethal concentration (LC50-96h), effective concentration (EC50-96h), risk assessment, and development of Nile tilapia Oreochromis niloticus larvae submitted to florfenicol (FF) exposure. Fish (n-147; 8.6 ± 0.6 mg; 7 fish/aquarium) were randomly distributed in 21 aquaria (1 L) and exposed to five concentrations of FF 58.73; 131.31; 198.96; 241.88 and 381.81 mg L-1 plus one control and a control with solvent, totalizing seven treatments and three replicates. The estimated median LC50-96h of FF for Nile tilapia larvae was 349.94 mg L-1. The EC50-96h of FF was 500 mg L-1 for weight reduction and was 1040 mg L-1 for length reduction. After the exposure period, final weight and length differed (p < 0.05) among treatments, showing the lowest biometric values with the highest concentrations of FF. The pH and dissolved oxygen were altered (p < 0.05) during the experimental period. The FF high doses used to determine the LC 50 after 96 h negatively affected the development of the larvae. On the other hand, through risk assessment analysis this antibiotic can be classified as low toxicity to Nile tilapia larvae and show low environmental risk. |
