Abstract

Introduction: Environmental factors affect on foodstuff quality. Because pigs and humans eat same foodstuffs (cereals, potatoes and dairy products) we could expect that time-related changes in them could show simultaneous health changes in both of them. In this study are assayed female (F) and male (M) mortality changes in coronary heart disease (CHD) and their associations with pig autopsy parameters. Data are presented from period 1951-2000, but statistically analyzed from period 1954-86 including autopsy density per 100,000 pigs [A.1/100,000], autopsy percents of microangiopathy [MAP.a-%] and cardiovascular diagnoses total [CVD.tot.a-%], visually myocardial degeneration [MyCD.a-%], hepatosis diaetetica [HeD.a-%] and skeletal muscle degeneration [SMuD.a-%].

Results: During 1954-86 [A.1/100,000], [MAP.a-%], [CVD.tot.a-%] and combined regressions with [MAP.a-%;A.1/100,000] and [CVD.a- %;A.1/100,000] explained stronger F.CHD than M.CHD. All the female associations were significant (weakest by MAP.a-%: p = 0.001, not below 0.001). Autopsy density associated stronger than the other given single parameters with F.CHD and M.CHD. [MyCD.a-%] was associated with changes in Hepatopathia diaetetica [HeD.a-%]. It decreased deeply in 1963 and discontinued since 1970.

Discussion: Similar variation in F.CHD and cardiac mortality of pig is suggestive on common, obviously dietary factors. In this article is discussed on exogenous grain fat peroxides, which are known in the etiology of livestock diseases, their associations with climatic factors, farming procedures and food processing. These changes have been counteracted by changes in feed supplementation, fertilization, agricultural procedures and grain farming shift southwestwards. F.CHD and Pig MAP decline below their 1957 levels until 1972, before respective male CHD decline, can be explained by lesser tobacco consumption.

Conclusions: Pig cardiac mortality associated significantly with female CHD, less significantly with male CHD. These associations seem possible to be explained by variation inside the foodstuffs and different smoking habits. Food peroxides are discussed. Different opinions and the great database of veterinary surgeons need co-working by veterinary and medical universities.
