The 39.25% of the calvings occured from December to February and only the 14.38% from August to October. The heifers and cows of seventh, eighth, tenth and eleventh and following calving showed an IBC higher than the cows of third, fourth, fitth and sixth calving. The variable “cow” had significant effect on the IBC, but the factors “gender of suckled calf”, “year”, “bull”, “calving month”, “fence” and, “body condition score at calving” had not significant influence on IBC. The age at first calving had not significant effect on IBC of heifer and average IBC of cows. Age at weaning of born calves from November to March was significantly lower than those born calves from May to July. The calf’s mortality seems affected by the genetic type of calf and the birth time. The use of Charolais bulls leads to a calves mortality at birth higher regarding Limousine bulls.

The degree of deformation of the neck, neck diameter, neck length, horse weight, athletic activity, place, feeding, handling and facilities were characterized. A descriptive statistical analysis was performed and the correlation coefficient between the degree of deformity and the environmental factors was estimated. A total of 4651 horses were studied. The deformation of the dorsal border of the neck was observed in 409 horses (8,79%). A greater number of horses with dorsal cervical deformity was observed in Andalucia (73%), than in Extremadura (27%). 54% of the horses were stabulated in a traditional system, while 46% were managed by a technified system. The alimentation protocol based exclusively on concentrated feed was observed in 19% of the farms, based on forage only 42%, and the combined concentrated feed and forage was found in 39% of the farms. The degree of deformity in relation to the exclusive feeding with feed showed a correlation level of 0,058. These results indicate that feed based on feed, feeders with an alturae of 100-160 cm, and the low activity may not have an association with the development of the deformation of the dorsal border of the neck. In conclusion the results show that the environment can directly influence the deformation of the dorsal border of the neck. A. Morales Briceño J.L. Méndez Angulo A. Méndez Sánchez J.

Daily life used to take place in a crowded environment, where malnutrition and poverty thrived. Direct or indirect fecal contamination from humans and animals of water and food was highly probable. Spills and pollution of watercourses and reservoirs with filth and carrion occurred often, this favoring pathogens and vectors. The lack of appropriate cleansing of streets and sewers, and the regular presence of animals –insects included– in streets and households guaranteed some more health challenges. These, and some other risk factors, supported both the appearance of large epidemics and the maintenance of endemic transmissible diseases including zoonoses.
