Abstract: Recent genetic improvement has developed pigs with maximum potential for protein deposit at higher weights; however, their optimal slaughter weight still needs to be determined. The objective of the study was to evaluate live performance, carcass traits, and economic viability of 417 Agroceres PIC pigs slaughtered with 100, 115, 130, and 145kg live weight. Pigs were reared in pens with 10-11 barrows and gilts each, offered a feed allowance of 2.8kg/pig/day until the following slaughter weights (SW):99.65±0.82kg, 118.53±0.98kg, 133.97±1.17kg, and 143.90±1.24. There was no interaction between sex and SW (P>0.05). Backfat thickness, fat area, and loin eye area linearly increased with SW (P<0.001; R2: 70.12-77.44%), and carcass yield increased in a quadratic manner (P<0.001; R²=24.66%). Lean yield was not affected (P>0.05), and feed conversion ratio (R²=43.29%) linearly worsened with SW (P<0.001), but the effect of SW on live production cost (R$/kg) was quadratic, with the minimum point at 134.8kg. It was concluded that, under the applied management, increasing SW results in larger amount of lean tissue with no change in its yield and little effect on growth performance. Resumo: A evolução das linhagens sintéticas de suínos propiciou a obtenção de animais com potencial máximo de deposição proteica em pesos superiores; entretanto o peso ótimo de abate dessas linhagens não é conhecido. O objetivo do estudo foi avaliar o desempenho, características de carcaça e avaliação econômica de 417 suínos da linhagem Agroceres PIC abatidos com 100, 115, 130 e 145kg de peso vivo. Os suínos foram criados em baias com 10-11 machos ou fêmeas, com fornecimento programado de 2,8kg de ração por animal, por dia, a partir de 80kg até os pesos de abate (PA) de 99.65±0.82kg, 118.53±0.98kg, 133.97±1.17kg, e 143.90±1.24. Não houve interação entre sexo e PA (P>0,05). A espessura de toucinho, área de gordura e área de olho de lombo aumentaram linearmente com o PA (P<0,001; R² entre 70,12 e 77,44%), e o rendimento de carcaça aumentou de forma quadrática (P<0,001; R²=24,66%). A porcentagem de carne magra não foi afetada (P>0.05) e a conversão alimentar (R²=43,29%) apresentou discreta piora linear com o PA (P<0,001), mas o efeito sobre o custo de produção (R$/Kg) foi quadrático, com ponto de mínima aos 134,85kg. Conclui-se que, com o manejo utilizado, a elevação do PA resulta em aumento na quantidade de carne produzida sem alteração no seu rendimento e apresenta pouco efeito sobre o desempenho.

The evolution of sex determination (SD) in teleosts is amazingly dynamic, as reflected by the variety of different master sex-determining genes identified. Pangasiids are economically important catfishes in South Asian countries, but little is known about their SD system. Here, we generated novel genomic resources for 12 Pangasiids and characterized their SD system. Based on a Pangasianodon hypophthalmus chromosome-scale genome assembly, we identified an anti-Müllerian hormone receptor type II gene (amhr2) duplication, which was further characterized as being sex-linked in males and expressed only in testes. These results point to a Y chromosome male-specific duplication (amhr2by) of the autosomal amhr2a. Sequence annotation revealed that the P. hypophthalmus Amhr2by is truncated in its N-terminal domain, lacking the cysteine-rich extracellular part of the receptor that is crucial for ligand binding, suggesting a potential route for its neofunctionalization. Reference-guided assembly of 11 additional Pangasiids, along with sex-linkage studies, revealed that this truncated amhr2by duplication is a male-specific conserved gene in Pangasiids. Reconstructions of the amhr2 phylogeny suggested that amhr2by arose from an ancient duplication/insertion event at the root of the Siluroidei radiation that is dated to ~100 million years ago. Together these results bring multiple lines of evidence supporting that amhr2by is an ancient and conserved master sex-determining gene in Pangasiids, a finding that high-lights the recurrent use of the transforming growth factor ? pathway, which is often used for the recruitment of teleost master SD genes, and provides another empirical case towards firther understanding of dynamics of SD systems.
