Resumo: | The objective of this study was to evaluate the influence of phenotype on the reproductive efficiency of sheep and the performance of lambs from birth to weaning. were used of 111 adult Corriedale ewes (54 natural colored and 57 white), kept in natural pasture, supplemented in the final third of gestation and grazed in improved natural pasture after birth. The matings were performed by artificial insemination and controlled mount. After birth, the lambs were weighed at mean intervals of 28 days and weaned at a mean age of 146 days. The experimental design was the entirely randomized, where each sheep represented an experimental unit. The continuous response variables were submitted to analysis of variance and the discrete ones to the Chi-square test. The weight and body condition before mating the sheep, the percentages of pregnancy, calving, gemiparity and losses during gestation, the weight of lambs at birth and the mortality rate until weaning did not differ between groups (P>0.05). White Corriedale ewes presented higher weaning rate of lambs (P<0.05). The phenotype (maternal and filial) influenced the average daily weight gain and weight at weaning (P<0.05). The naturally colored phenotype of sheep or lambs determines greater weaning weights, regardless of the coloring of the mother. |

Se utilizaron 111 ovejas Corriedale adultas (54 naturalmente coloreadas y 57 blancas), mantenidas en pastos naturales, suplementadas en el último tercio de la gestación y pastoreadas en pastos naturales mejorados después del parto. El emparejamiento se realizó mediante inseminación artificial y apareamiento controlado. Tras el nacimiento, los corderos fueron pesados con intervalos medios de 28 días y destetados a una edad media de 146 días. El diseño experimental fue totalmente aleatorio, donde cada oveja representaba una unidad experimental. Las variables de respuesta continuas se sometieron al análisis de la varianza y las variables de respuesta discretas a la prueba de Chi-cuadrado. El peso y la condición corporal previa a la cubrición de las ovejas, los porcentajes de gestación, parto, gemelación, pérdidas durante la gestación, el peso de los corderos al nacimiento y la tasa de mortalidad hasta el destete no difirieron entre los grupos (P>0,05). Las ovejas Corriedale blancas mostraron una mayor tasa de destete de corderos (P<0,05). El fenotipo (materno y filial) influyó en el aumento de peso medio diario y en el peso al destete de los corderos (P<0,05). El fenotipo de color natural de las ovejas o de los corderos determina un mayor peso al destete de estos últimos, independientemente de la coloración de la madre.O objetivo deste trabalho foi avaliar a influência do fenótipo na eficiência reprodutiva de ovelhas e o desempenho dos cordeiros do nascimento ao desmame. Foram utilizadas 111 ovelhas adultas da raça Corriedale (54 naturalmente coloridas e 57 brancas), mantidas em pastagem natural, suplementadas no terço final da gestação e pastoreadas em pastagem natural melhorada após o parto. Os acasalamentos foram realizados por inseminação artificial e monta controlada. Após o nascimento, os cordeiros foram pesados em intervalos médios de 28 dias e desmamados a idade média de 146 dias. O delineamento experimental foi o inteiramente casualizado, onde cada ovelha representou uma unidade experimental. As variáveis resposta contínuas foram submetidas à análise de variância e as discretas ao teste Qui-quadrado. O peso e a condição corporal pré-acasalamento das ovelhas, os percentuais de prenhez, parição, gemiparidade, perdas durante a gestação, peso dos cordeiros ao nascimento e a taxa de mortalidade até o desmame não diferiram entre os grupos (P>0,05). Ovelhas Corriedale brancas apresentaram maior taxa de desmame de cordeiros (P<0,05). O fenótipo (materno e filial) influenciou o ganho médio diário de peso e o peso ao desmame dos cordeiros (P<0,05). O fenótipo naturalmente colorido das ovelhas ou dos cordeiros determina maiores pesos ao desmame destes últimos, independente da coloração da progenitora.Research, Society and Development2022-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2676310.33448/rsd-v11i5.26763Research, Society and Development; Vol. 11 No. 5; e11911526763Research, Society and Development; Vol. 11 Núm. 5; e11911526763Research, Society and Development; v. 11 n. 5; e119115267632525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/26763/24387Copyright (c) 2022 Pablo Tavares Costa; Gilson de Mendonça; Ricardo Zambarda Vaz; Larissa Picada Brum; Maurício Prestes Bragagnollo; Thiago Pereira Vieirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCosta, Pablo Tavares Mendonça, Gilson de Vaz, Ricardo Zambarda Brum, Larissa Picada Bragagnollo, Maurício Prestes Vieira, Thiago Pereira 2022-04-17T18:18:56Zoai:ojs.pkp.sfu.ca:article/26763Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:43.341779Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
