“…In cattle, dystocia has been found to be related to several negative outcomes, such as survival of newborn calves (Eriksson et al, 2004;Bicalho et al, 2008;Barrier et al, 2013). This is so because dystocial calves normally experience higher physiological stress, acidosis and hypoxic state which result in lower vigor (Barrier et al, 2012;Kovács et al, 2016) and consequently in reduction in the transfer of passive immunity, as well as important metabolic changes (Barrier et al, 2013;Vannucchi et al, 2015). Stillborn calves from dystocic parturition not necessarily exhibit specific types of trauma, but do exhibit larger lesions than their eutocic counterparts, indicating that they experienced greater trauma during delivery (Barrier et al, 2013).…”

Risk factors for stillbirth were studied in a dairy operation in northern Mexico (25°N). Data set consisted of 29406 full term calving records. Factors affecting stillbirths were analyzed using a step-wise multivariable logistic regression models. The predictive indicators of stillbirth risk were: temperature-humidity index (THI) during pregnancy and at calving, season of calving, calf birth weight, gestation length, semen characteristics (conventional or sexed), gender of calves, hour of calving and type of parturition (normal or dystocic). Throughout the study period, 7.3 (95%, confidence interval= 7.0-7.6) of every 100 calving events had a stillborn calf. Stillborns were higher with severe dystocia compared with non-assisted births (29.0% vs. 6.2%, p<0.0001) and calves with birth weights <35 kg compared with heavier calves at calving (19.3% vs. 2.3%, p<0.0001), and was lower in calves whose gestation length was >278 d compared with calves with shorter gestation periods (2.8% vs. 30.0%, p<0.0001). Cows in a severe state of heat stress prenatally and at birth (THI >83 units) had 1.3 higher risk of stillbirths than cows suffering reduced heat stress (p<0.0001). Evidence for a greater (p<0.001) stillbirth rates in cows with parturitions between 18:00 and 19:00 h compared with cows calving during other hours of the day was found (9.1% vs. 7.1%). Together, these results demonstrate that ameliorating heat stress during the peripartum period is an important management practice to reduce stillbirths in Holstein cows in this warm climate. Additionally, a greater attention of parturition around sunset can lower the current stillbirth rates.Additional keywords: heat stress; sexed semen; birth weight; dystocia; gestation length

“…It has been suggested that calves born from a difficult birth may suffer from reduced vigor [10]. Reduced vigor may result in short and long-term consequences for the health and productivity of the calf, and economic losses for the producer.…”

“…Reduced newborn calf vigor from dystocia can result from injury, inflammation, inability to maintain homeostasis, as well as from hypoxia and acidosis [1,[7][8][9]. These physiological effects can have behavioral repercussions, such as having reduced motivation to perform natural behaviors for survival, including standing up and suckling colostrum after birth [10]. Attempts have been made to assess the vigor of newborns through scoring systems.…”

“…Dystocia in cattle results in many adverse consequences for the dam and its off spring (Azizzadeh et al, 2012;Barrier et al, 2012). These include increased calf morbidity and mortality, decreased fertility and milk production, low cow survival and reduced welfare (Mee et al, 2011).…”

Comparison between data mining methods to assess calving diffi culty in cattle ¤ Comparación entre métodos de minería de datos para evaluar la difi cultad al parto en ganado AbstractBackground: Dystocia in cattle results in adverse consequences (increased calf morbidity and mortality, decreased fertility, and milk production, lower cow survival and reduced welfare) leading to considerable economic losses. Objective: To classify calvings in dairy cattle according to their diffi culty using selected data mining methods [classifi cation and regression trees (CART), chi-square automatic interaction detection trees (CHAID) and quick, unbiased, effi cient, statistical trees (QUEST)], and to identify the most signifi cant factors aff ecting calving diffi culty. The results of data mining methods were compared with those of a more traditional generalized linear model (GLM). Methods: A total of 1,342 calving records of Polish HolsteinFriesian black-and-white heifers from four farms were used. Calving diffi culty was divided into three categories (easy, moderate and diffi cult). Results: The percentages of calvings correctly classifi ed by CART, CHAID, QUEST, and GLM were as follows: 35.14, 18.92, 19.82, and 43.24% (easy), 68.70, 73.91, 81.74, and 41.74% (moderate), and 77.27, 85.45, 73.64, and 81.82% (diffi cult), respectively. The most important factors aff ecting calving diffi culty were bull's rank (based on the mean calving diffi culty score of its daughters), calving age, farm category (based on its mean milk yield) and calving season. Conclusion: All classifi cation models were satisfactory and could predict the class of calving diffi culty.
