Resumo: The objective of this study was to evaluate the impact of cow's weight variation during gestation on the development and productive characteristics of the carcass and the meat of heifers slaughtered at 18 months of age. Thirty - five cows and their progeny were used. The evaluated treatments were determined according to the matrix weight variation during gestation, expressed as a percentage of the live weight of the matrix at the end of the breeding period. Treatments were: G10, cows that gained from 0.1 to 10.0% of live weight during gestation; P10, cows that lost 0.1 to 10.0% of live weight during gestation; P20, cows that lost from 10.1 to 20.0% of live weight during gestation. Data were analyzed statistically through multivariate analysis and the main components technique. The variables PNAS, PAJDESM, PAJ365, PAJ420, PAJ540, GMD, RCQ, RCF, AOL, GORD, ICC, DIAN, COST, CON, MAT and EGS of heifers were not influenced by maternal performance during gestation. The PCQ, PCF, MUSC, OSSO, TRAS and MARM presented significant correlation with two main components. The G10 treatment presented higher values for PCQ, PCF, TRAS, MUSC and MARM, being located in the I quadrant. Treatment P10 presented a greater amount of OSSO in the carcass, in the IV quadrant. On the other hand, the P20 treatment was located in the II quadrant, presenting the worst values for these variables. The variation in the weight of the cow during pregnancy does not influence the development of the progeny, but it does impact the carcass and meat characteristics.

Se utilizaron 35 vacas y su progenie. Los tratamientos evaluados se determinaron de acuerdo con la variación de peso de la matriz durante la gestación, expresada como porcentaje del peso vivo de la matriz al final del período reproductivo. Los tratamientos fueron: G10, vacas que ganaron 0,1 a 10,0% del peso vivo durante la gestación; P10, vacas que perdieron de 0.1 a 10.0% del peso vivo durante la gestación; P20, vacas que perdieron del 10,1 al 20,0% del peso vivo durante la gestación. Los datos se analizaron estadísticamente mediante análisis multivariado y la técnica de componentes principales. Las variables PNAS, PAJDESM, PAJ365, PAJ420, PAJ540, GMD, RCQ, RCF, AOL, GORD, ICC, DIAN, COST, CON, MAT y EGS no fueron influenciadas por el desempeño materno. El PCQ, PCF, MUSC, OSSO, TRAS y MARM presentaron una correlación significativa con dos componentes principales. El tratamiento G10 mostró valores más altos para PCQ, PCF, TRAS, MUSC y MARM, ubicándose en el cuadrante I. El tratamiento P10 mostró una mayor cantidad de HUESO en la canal, en el cuadrante IV. El tratamiento P20 se ubicó en el cuadrante II, presentando los peores valores para las variables referidas. La variación en el peso de la vaca durante la gestación no influye en el desarrollo de la progenie, pero sí afecta las características de la canal y la carne.Objetivou-se avaliar o impacto da variação de peso da vaca durante a gestação no desenvolvimento e nas características produtivas da carcaça e da carne de novilhas abatidas aos 18 meses de idade. Foram utilizadas 35 vacas e sua progenie. Os tratamentos avaliados foram determinados de acordo com a variação de peso da matriz durante a gestação, expresso em porcentagem do peso vivo da matriz no final do período de reprodução. Os tratamentos foram: G10, vacas que ganharam de 0,1 a 10,0 % do peso vivo durante a gestação; P10, vacas que perderam de 0,1 a 10,0 % do peso vivo durante a gestação; P20, vacas que perderam de 10,1 a 20,0 % do peso vivo durante a gestação. Os dados foram analisados estatisticamente através de análise multivariada e da técnica de componentes principais. As variáveis PNAS, PAJDESM, PAJ365, PAJ420, PAJ540, GMD, RCQ, RCF, AOL, GORD, ICC, DIAN, COST, CON, MAT e EGS não foram influenciadas pelo desempenho materno durante a gestação. Já o PCQ, PCF, MUSC, OSSO, TRAS e MARM apresentaram correlação significativa com dois componentes principais. O tratamento G10 apresentou maiores valores para PCQ, PCF, TRAS, MUSC e MARM, ficando localizadas no quadrante I. O tratamento P10 apresentou maior quantidade de OSSO na carcaça, no quadrante IV. Já o tratamento P20 ficou localizado no quadrante II, apresentando os piores valores para as referidas variáveis. A variação de peso da vaca durante a gestação não influencia no desenvolvimento da progênie, porém impacta nas características de carcaça e carne.Research, Society and Development2021-02-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1207710.33448/rsd-v10i2.12077Research, Society and Development; Vol. 10 No. 2; e14110212077Research, Society and Development; Vol. 10 Núm. 2; e14110212077Research, Society and Development; v. 10 n. 2; e141102120772525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/12077/11070Copyright (c) 2021 Leonel da Silva Rodrigues; Amanda Farias de Moura; Dari Celestino Alves Filho; Ivan Luiz Brondani; John Lenon Klein; Sander Martinho Adams; Joziane Michelon Cocco; Lucas Braido Pereirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRodrigues, Leonel da SilvaMoura, Amanda Farias deAlves Filho, Dari CelestinoBrondani, Ivan LuizKlein, John LenonAdams, Sander MartinhoCocco, Joziane MichelonPereira, Lucas Braido2021-03-02T09:32:39Zoai:ojs.pkp.sfu.ca:article/12077Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:33:45.169034Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
