Resumo: | This study aimed to assess how maternal nutrition in the final third of gestation affects progeny weight performance and body composition. Forty-one steers were included, born to cows subjected to different nutritional levels during this period: 13 cows without supplementation and under nutritional restriction (RES), 16 cows supplemented to meet 100% of requirements (REQ), and 12 cows supplemented to meet 150% of requirements (HIGH). The study design was completely randomized. Progeny performance was not influenced by maternal nutrition during gestation (P > 0.05). However, RES animals excelled during challenging periods, while REQ and HIGH animals performed better in nutritionally favorable environments. Maternal nutrition in the final third of gestation did not impact the contribution of non-carcass components (16.42%) and internal organs (3.17%). RES and HIGH steers had a higher relative weight of the rumen (2.48%) compared to REQ steers (2.24%), resulting in a greater proportion of the gastrointestinal tract (8.25% vs. 7.63%). Carcass characteristics did not differ significantly between treatments (P > 0.05), with an average hot carcass weight and yield of 304.28 kg and 57.80%, respectively. The primary fore, side, and hind cuts represented 39.22%, 10.64%, and 50.67% of the carcass, respectively. Overall, maternal nutrition during gestation affects fetal development, leading to modifications in body composition and, consequently, the productive potential of the offspring.Keywords: carcass yield; gastrointestinal tract; slaughter weight; vital organs |

Foram utilizados 41 novilhos de vacas submetidas a diferentes níveis nutricionais durante o terço final de gestação: 13 vacas sem suplementação sob restrição nutricional (RES); 16 vacas suplementadas para atender 100% das exigências (REQ); 12 vacas suplementadas para atender 150% das exigências (HIGH). O delineamento experimental foi inteiramente casualizado. O desempenho da progênie não foi influenciado pela nutrição materna na gestação (P > 0,05), porém, animais RES se sobresaem em períodos desafiadores, enquanto que os REQ e HIGH desempenharam melhor em ambientes nutricionalmente favoráveis. A nutrição materna no terço final da gestação não influenciou a participação dos componentes não carcaça (16,42%) e órgãos internos (3,17%). O peso relativo do rúmen foi maior nos novilhos RES e HIGH (2,48%) em relação aos novilhos REQ (2,24%), resultando em maior participação do trato gastrointestinal (8,25 vs 7,63%, respectivamente). As características quantitativas da carcaça foram semelhantes entre os tratamentos (P > 0,05), com peso médio de carcaça quente e rendimento equivalente a 304,28 kg e 57,80%. A participação dos cortes primários dianteiro, lateral e traseiro foi de 39,22, 10,64 e 50,67%, respectivamente. Diante do exposto, concluímos que a nutrição materna na gestação afeta a formação fetal de modo a modificar a composição corporal e consequentemente o potencial produtivo dos descendentes.Palavras-chave: órgãos vitais; peso de abate; rendimento de carcaça; trato gastrointestinalUniversidade Federal de Goiás2023-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://revistas.ufg.br/vet/article/view/74730Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 24 (2023): Continuous publicationCiência Animal Brasileira / Brazilian Animal Science; v. 24 (2023): Publicação contínua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporenghttps://revistas.ufg.br/vet/article/view/74730/39830https://revistas.ufg.br/vet/article/view/74730/40027https://revistas.ufg.br/vet/article/view/74730/39831https://revistas.ufg.br/vet/article/view/74730/40028Copyright (c) 2023 Ciência Animal Brasileira / Brazilian Animal Sciencehttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessKlein, John LenonAdams, Sander MartinhoAlves Filho, Dari CelestinoBrondani, Ivan LuizPizutti, Luiz Ângelo DamianCocco, Joziane Michelon2023-08-24T18:50:54Zoai:ojs.revistas.ufg.br:article/74730Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:34.695119Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
