| description | One of the productive practices in laying hens that causes controversy in the animal welfare area is the nutritional stress produced during the forced molt phase. The current research relates the experiment implemented to evaluate the effect of the Humic Substances (HS) on stress indicators during the post molting phase. 120 HyLine Brown laying hens were observed within the 60 first days of the post molting, which were divided in four groups: the first and second were supplemented with 0,1 and 0,2% of HS respectively, the third group was supplemented with 0,25 mg/kg of hydrochloride of levamisole, and the fourth was not supplemented at all; blood samples were taken the days 8, 30 and 60 to evaluate hematocrit and Heterophils/Lymphocytes relationship (H/L) and the tonic immobility was recorded from the days 30"‘ and 60"”. It was evidenced that the groups supplemented with HS improved the hematocrit by the day 30*, decreased the H/L relationship and the tonic immobility time days 30‘“ and 60‘“ (p<0,05).The results obtained in this research indicate that the HS from the cachaza, leaves and vinasse from the sugar production, perform as stress reliever agents in the early and middle phase of the post molting in Hy Line Brown laying hens. |

Una de las prácticas productivas en gallinas ponedoras que causa polémica es la muda forzada, debido al estrés nutricional al que son sometidas durante este período. Esta investigación evaluó el efecto de las sustancias húmicas (SH) en los indicadores de estrés durante la fase de posmuda. Se utilizaron 120 gallinas ponedoras Hy Line Brown, en los primeros 60 días de la posmuda, las cuales se dividieron en cuatro grupos: El primero y segundo grupo se suplementaron con 0,1 y 0,2% de SH, respectivamente, el tercer grupo se suplementó con 0,25 mg/kg de clorhidrato de levamisol, y el cuarto grupo no recibió suplementación.Se tomaron muestras sanguíneas los días 8,30 y 60, para evaluar hematocritos y relación heterófilos/linfocitos (H/L), y se registró la inmovilidad tónica (IT) los días 30 y 60.Se evidenció que los días 30 y 60, los grupos suplementados con SH incrementaron la concentración de hematocrito y disminuyeron la relación H/L y el tiempo de IT (p&lt,0,05). Los resultados obtenidos indican que las SH provenientes de la biotransformación de cachaza, hojas y vinaza de la producción de azúcar se comportan como agentes mitigadores de estrés en la fase temprana y media de la posmuda en gallinas ponedoras Hy Line Brown.
