Impact of lameness on production, reproduction and health of dairy cows

In order to investigate the consequences of lameness on dairy cattle productive, reproductive efficiency, and health, records from the software of 6 dairy farms located in central Argentina were studied. Two randomly chosen cow groups were compared: lame group (LG; n= 510) and healthy control group...

description In order to investigate the consequences of lameness on dairy cattle productive, reproductive efficiency, and health, records from the software of 6 dairy farms located in central Argentina were studied. Two randomly chosen cow groups were compared: lame group (LG; n= 510) and healthy control group without lameness (CG; n= 510). Milk liters at 305 days (L/305), total milk liters (TL), days in milk (DIM), open days (OD) insemination number (IN), calving intervals (CI), health disorders and culled or death cows were recorded. Parameters were taken in the initial lactation (IL) in which the lame occurred in LG or not in the CG and in their corresponding subsequent later lactation (LL). For the analysis a generalized mixed linear model, the chi-square test and Odds Ratio (OR) were used. Differences were found respectively in IL (p<0.0018) and LL (p<0.0017) in L/305 production between the LG (10939.3 and 10479.6 l) and CG (11542.8 and 11110.9 l). Regarding TL, in IL there were no significant differences (p<0.16), but in LL the TL was higher (p<0.001) in CG cows than in LG. In the IL, the OD, IN and CI of the LG exceeded (p<0.0001) those of the CG, but no differences were found in LL. During the IL, infertility problems (p<0.0001) and genital tract infections (p<0.007) were higher in the LG. In the LL, the number of lame cows (45.4%) was higher (p<0.0001) in the LG group than those of CG (9.26%). In the IL and LL, a greater number of cows (p<0.0001) in the LG had a higher probability of being culled or dead than those in the CG, IL: OR= 7.51, CI 4.7-11.8 and LL: OR= 5.82; CI 3.28 -10.3. The present study shows the damage caused by lameness to productive, reproductive and health indices of central Argentina dairy farms.

El objetivo de este trabajo fue determinar el impacto de las afecciones podales (AP) sobre la eficiencia productiva, reproductiva, la salud en vacas lecheras. A partir de los registros de los softwares de 6 tambos ubicados en las provincias de Córdoba y Entre Ríos, se conformaron 2 grupos de 510 vacas cada uno: grupo con AP (GAP) y grupo control sano (GCS). Se registraron la lactancia inicial en la que ocurrió o no el problema podal (LI) y en la lactancia posterior (LP), los litros de leche en 305 días (L/305), la leche total (LT), días abiertos (DA), número de inseminaciones (NI), intervalos entre partos (IPP), número de eventos de salud (ES) y número de vacas que continuaban en el tambo, vacas descartadas y muertas o sacrificadas. Para el análisis de las variables se utilizó un modelo lineal generalizado mixto y la prueba de chi cuadrado y el Odds Ratio (OR). Se encontraron diferencias en LI (p<0,0018) y LP (p<0,0017) en la producción L/305 respectivamente entre los grupos GAP (10939,3 y 10479,6 l) y GCS (11542,8 y 11110,9 l). En cuanto a la LT, en la LI no hubo diferencias significativas (p<0,16) entre grupos, pero sí en la LP la PT fue mayor (p<0,001) en las vacas del GCS que en las del GAP. En la lactancia LI, los DA, el NI y el IPP del GAP superaron (p<0,0001) a los de GCS, pero no se hallaron diferencias en la LP. Durante la LI, los problemas de infertilidad (p<0,0001) e infecciones del tracto genital en el gap(p<0,007) fueron más elevados en el GAP que en el GCS, pero sin diferencias (p<0,16) en cuanto a las mastitis. En la LP, el número de vacas del GAP que presentaron afecciones podales (45,4%) fue superior (p<0,0001) al número de vacas del GCS (9,26%). En la LI y la LP, un mayor número de vacas (p<0,0001) del GAP tuvo una mayor probabilidad de ser descartadas o muertas que las del GCS, LI: OR= 7,51, IC 4,7 – 11,8 y LP: OR= 5,82; IC 3,28 – 10,3. Estos resultados evidencian los daños productivos y sanitarios que causan las afecciones podales en los tambos del centro de la Argentina. EEA Salta Fil: Suárez, Víctor Humberto.
