Resumo: | This study evaluated the productive and reproductive performances of Santa Inês sheep and their Dorper crossbreeds during the lactation period amidst the dry season in the semi-arid region of Paraíba, Brazil. Conducted at the experimental goat farm of the State University of Paraíba (UEPB), Campus IV, Catolé do Rocha, the investigation included a cohort of 24 ewes (12 Santa Inês and 12 Dorper crossbreeds [comprising 87.5% Dorper and 12.5% Santa Inês]) and 30 lambs (10 males and 20 females). Observations were recorded from birth and continued at 30-day intervals up to 90 days. Using a two-way ANOVA with a 2 x 2 factorial design (two genetic groups and two sexes), the study monitored both ewes and lambs. The animals adhered to traditional regional management, grazing in paddocks by day and secured in shelters by dusk. The study found that both Santa Inês and Dorper crossbred ewes produced similar quantities of milk (P=0.8310) for the first 60 days of lactation. There was no discernible effect of the ewes’ genetic backgrounds on their live weights, body condition scores at lambing, throughout the subsequent 30, 60, and 90 days of lactation, or on the overall productive efficiency and total weight of weaned lambs per ewe. In contrast, Dorper lambs demonstrated a higher weaning weight (P=0.0349) and greater weight gain (P=0.0403). The study also noted that the sex of the lambs did not notably influence their performance within the first 90 days of suckling. |

O experimento foi conduzido no Setor de Caprinovinocultura da Universidade Estadual da Paraíba/UEPB/Campus-IV, Catolé do Rocha/PB. Foram utilizadas 24 ovelhas multíparas, sendo 12 da raça Santa Inês e 12 mestiças da raça Dorper (87,5% Dorper + 12,5% Santa Inês) paridas com 30 ovinos jovens, sendo 10 machos e 20 fêmeas. O período experimental se iniciou no momento do parto e os dados foram coletados ao nascimento, aos 30, 60 e 90 dias de idade. Foi utilizada análise de variância para as ovelhas e para os cordeiros esquema fatorial 2 x 2 (dois grupos genéticos e dois sexos). Os cordeiros permaneceram com suas mães em piquetes durante o dia e à noite no aprisco, manejo tradicional da região. As ovelhas Santa Inês e mestiças Dorper produziram quantidades de leite semelhantes (P=0,8310) até os 60 dias de lactação. O grupo genético das ovelhas não influenciou os pesos vivos e escore de corporal ao parto, 30, 60 e 90 dias de lactação, como também a eficiência produtiva e peso total de crias desmamadas por ovelha. Os cordeiros e cordeiras Dorper apresentaram maiores pesos vivos (P=0,0349) e ganhos de peso (P=0,0403), por outro lado, o sexo dos ovinos jovens não influenciou o desempenho até os 90 dias de amamentação.Universidade Federal de Goiás2024-01-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://revistas.ufg.br/vet/article/view/75817Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 25 (2024): Publicação continuaCiência Animal Brasileira / Brazilian Animal Science; v. 25 (2024): Publicação continua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporenghttps://revistas.ufg.br/vet/article/view/75817/40731https://revistas.ufg.br/vet/article/view/75817/40732https://revistas.ufg.br/vet/article/view/75817/40858https://revistas.ufg.br/vet/article/view/75817/40859Copyright (c) 2024 Ciência Animal Brasileira / Brazilian Animal Sciencehttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBrandão, Júlio César de Araújo Bezerra Cartaxo, Felipe QueirogaPinto, Maria do Socorro de Caldas Targino, Luciano CamposGomes, Rayane NunesSouza, Daniela Dourado Romão deCardoso, André Filipe Monteiro Morais, Larissa Kellen da CunhaFarias, Carolina Araujo de Ramos, João Paulo de Farias2024-03-09T21:11:36Zoai:ojs.revistas.ufg.br:article/75817Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:36.995278Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
