Resumo: | The objective of this study was to evaluate the effects of crude glycerin (CG) supplementation of dairy ewes during pregnancy and early lactation on the body weight and measurements of offspring from birth to weaning. Twenty-four lambs from 24 Lacaune x East Friesian genotype ewes were evaluated. The sheep were distributed in four treatments that differed in crude glycerin supplementation of 0%, 1.5%, 3.0%, and 4.5%, as well as the concomitant adjustment of dry matter and water intake. Body measurements of lambs were recorded every two weeks from birth until weaning. Body weight was recorded daily. Multiple regression analysis revealed that supplementation with CG explained 5.2% of the variation in the weight of lambs at birth (LW), accompanied by the body condition score of the ewe (12.3%), sex of lamb (19.2%), and live weight of the ewes (26.5%); r2 was 63%. According to the predictions of the model adjusted for simulated scenarios, the leanest lambs were derived from ewes weighing between 40 and 50 kg, with body condition scores from 4 to 5, and that did not receive CG at intermediate levels. Heavier lambs, with LW above 5.5 kg, were derived from ewes that weighed between 80 to 90 kg with low body condition scores of 3, and that received 1.5% CG. Supplementation with CG between 2% and 4% improves the weight of the lambs at birth. Body measurements of lambs were not influenced by dietary supplementation of ewes with CG. |

Foram avaliados 24 cordeiros oriundos de 24 ovelhas do genótipo Lacaune x East Friesian distribuídas em quatro tratamentos que se diferenciaram quanto à suplementação de GB na dieta em (0; 1,5; 3,0 e 4,5% de MS) sendo esta adicionada à água. As medidas biométricas dos cordeiros oriundos das mães avaliadas ocorreram quinzenalmente do dia do nascimento até o período da desmama, já o peso corporal foi avaliado diariamente. O estudo de regressão múltipla realizado constatou que o teor de GB na dieta das mães explicou 5,2% da variação no peso dos cordeiros ao nascer (PN), seguidas pelo escore corporal das mães (12,3%), sexo do cordeiro (19,2%) e peso vivo das mães (26,5%), totalizando r2 de 63%. Segundo predições do modelo ajustado para cenários simulados, cordeiros mais leves foram oriundos de ovelhas com peso entre 40 a 50 kg, escore 4 a 5 e que não receberam GB em níveis intermediários. Cordeiros mais pesados, com PN superior a 5,5, provinham de ovelhas pesadas, entre 80 e 90 kg com escore baixo e que receberam níveis de 1,5 e 3% de GB. A suplementação com GB entre 2% e 4% melhora o peso ao nascer dos cordeiros. As medidas corporais dos cordeiros não são influenciadas pela suplementação com GB na dieta das mães.UEL2016-09-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2349210.5433/1679-0359.2016v37n4Supl1p2567Semina: Ciências Agrárias; Vol. 37 No. 4Supl1 (2016); 2567-2576Semina: Ciências Agrárias; v. 37 n. 4Supl1 (2016); 2567-25761679-03591676-546Xreponame:Semina.
