Com o objetivo de determinar o peso otimo de abate de suinos, avaliou-se o ganho de peso diario medio (GPDM), consumo de racao diario medio (CRDM) e conversao alimentar (CA) de suinos Landrace x Large White dos 25 aos 80, 100, 120 e 140 kg de peso vivo (PV), respectivamente tratamentos I, II, III e IV. Quinze machos castrados e quinze femeas foram usados em cada tratamento, recebendo agua e racao a vontade. O PV aumentou linearmente com a idade. O GPDM aumentou curvilineamente com o PV. O tratamento III apresentou maior GPDM do que os tratamentos I e IV (P<0,05), e maior, embora nao significativamente, do que o do tratamento II (P>0,05). Os machos castrados apresentaram maior GPDM do que as femeas (P<0,01). Os tratamentos III e IV apresentaram maior CRDM do que os tratamentos I e II (P<0,05). O tratamento IV apresentou a pior CA (P<0,05). Diferencas de CA entre os tratamentos I e II e entre os tratamentos II e III nao foram significativas (P>0,05). Os resultados sugerem que o desempenho dos animais foi melhor nos tratamentos I, II e III do que no tratamento IV. A escolha entre 80, 100 ou 120 kg como peso otimo de abate, depende de condicoes economicas vigentes no mercado. |

ABSTRACT: Ruzigrass (Urochloa ruziziensis) is a diploid, tropical forage grass native to Africa, widely planted in Brazil, and known for its high nutritional quality. It is closely related to other important forage species of Urochloa, playing a crucial role in the breeding program of brachiaria grasses, which is mostly focused on inter-specific hybrids. Previous studies from our group based on shallow Illumina sequencing resulted in the development of the first molecular markers for the species, as well as in assessments of germplasm diversity and structure. Assembly and analysis of complete plastid genomes for four Urochloa species allowed the characterization of their phylogenetic divergence. Here, we strengthen the set of genomic tools for tropical forage grasses by assembling long reads into a first draft for the nuclear genome of the heterozygous clone C69. We used PacBio Sequel to generate over 13.3 million raw reads (mean size 6.5 kbp), adding up to 87.5 Gbp of raw data (~142x coverage). The current assembly using FALCON contains ~1.02 Gbp in 7,628 primary contigs, with NG50 of 412 kbp. It covers almost twice the size of the estimated haploid genome size of 615 Mbp for ruzigrass, indicating that haplotypes were assembled separately. In addition, RNA-seq data was obtained, totaling 258 million reads and 26 Gbp of raw data. These will allow transcriptome characterization for different tissues and aid gene prediction and annotation. Ongoing research includes haplotype phasing, polishing, assembly curation and Hi-C scaffolding. A high-quality genome assembly for ruzigrass will aid research groups in the development and application of genomic tools in breeding and genetics of brachiaria grasses.
