O objetivo desta pesquisa foi avaliar a influência da sanificação usando peróxido de hidrogênio (H2O2) e dicloro isocianurato de sódio (NaDCC) em melão ´Amarelo´minimamente processado visando diminuir a carga microbiana, com consequente aumento no período da vida de prateleira. Para a limpeza superficial dos frutos usou-se detergente comercial e água. Os frutos limpos foram mergulhados em solução de H2O2 5% a 50°C por 15 minutos. Logo após, estes foram descascados, retiradas as sementes, cortados em cubos e mergulhados por 3 minutos em soluções de NaDCC (50, 100 e 200 ppm), H2O2 (2%, 4% e 6%) e água destilada (controle). Para a avaliação sensorial foram testados apenas os tratamentos H2O2 2%, NaDCC 50 ppm e controle. Após a sanificação, os frutos foram acondicionados em embalagens de polietileno e armazenados a 4°C por 15 dias. As análises realizadas foram: fungos filamentosos e leveduras, microrganismos aeróbios mesófilos e psicrotróficos, coliformes a 35°C e 45°C, bactérias do ácido lático, determinação da presença de Escherichia coli, quantificação de Staphylococcus coagulase positivo, sólidos solúveis totais (SST), pH, acidez total titulável (ATT), perda de massa, sabor, textura, aparência e cor. Os tratamentos com H2O2 4% e 6% foram mais efetivos em reduzir as contagens de fungos filamentosos, leveduras e coliformes a 35°C. |

The objective of the study was to evaluate feed efficiency of Nellore young bull in the feedlot using the evaluation of the residual feed intake (RFI). The experiment was carried out at the experimental farm Orestes Prata Tibery Júnior (ABCZ), located in Uberaba, MG, Brazil (lat. 19º 47' 68" S.; long. 47º 58' 50'' W, 788 m West). Nellore young bulls (n = 101), pure breed, with initial age of 17 months and mean live weight of 486 kg were housed in a feedlot containing electronic troughs and weighing scales. The experimental period lasted 98 days, with 28 of adaptation and 70 days of evaluation, from 03/17/2021 to 06/23/2021. The diet was formulated to provide 1.700 kg live weight/head/day and had a forage:concentrate ratio of 40:60, with 40% of corn silage and 60% of concentrate, containing 15.3% CP and 76.8% TDN on dry matter (DM) basis. The RFI was determined during the experimental period and the animals were separated in two experimental groups: positive and negative RFI. It was evaluated average daily gain (ADG), feed conversion (FC), daily dry matter intake (DMI) and gross feed efficiency (GFE). The experimental design was completely randomized and means were compared using Tukey test at 5% significance. In the evaluation of 101 young bulls, 56 had negative RFI and 45 had positive RFI, about 55.4% had lower DMI compared to estimated, which was considered the most efficient. The difference between the lowest and the highest individual intake followed was -1.87 kg (negative RFI) and 3.52 kg (positive RFI), with the difference of 5.39 kg of RFI, showing variability and chance of selection for more efficient and lower cost young bulls. It was observed effect of youn bull RFI group on DMI - 13.59 and 12.05 kg/day, and 2.51 and 2.24% LW, respectively for positive and negative RFI. There was a reduction of 11.3% in DMI during the experimental period. Feed conversion (6.28 and 6.93 kg of DM/kg ADG for negative and positive RFI) and GFE (0.16 and 0.15 kg ADG/kg DMI for negative and positive RFI) were influenced by RFI group. There was no effect (P>0.05) of RFI group on ADG - 1.95 (negative RFI) and 1.98 kg/head/day (positive RFI). Young bulls presenting negative RFI had lower intake with the same ADG, enabling better-feed conversion in the finishing phase, which directly affects the reduction of feed and production costs.
