[Use of partly hydrolyzed and untreated straw meal in the feeding of breeding sows. 4. Influence on embryonic mortality and fertility].
The influence of a supplement of variously treated straw materials to a ration to dry concentrate (= 1), (untreated = 2, steamed = 3, HCl-treated = 4 and partly hydrolysed = 5) during gestation on fertility and rearing performance, the embryonic survival quota of fertilized ova as well as on some selected metabolites in the blood serum was studied in 3 experiments. The integration of untreated straw meal resulted in significantly diminished performances in comparison to test groups 1 and 5 in all tested parameters of fertility and rearing performance (weight of litter). The best results were achieved in all experiments with rations of concentrate and partly hydrolysed straw meal. The individual test groups the following performance values (number of piglets born alive, weight of litter in kg) were achieved: 1 = 9.3, 12.3; 2 = 6.5, 8.2; 3 = 7.5, 9.6; 4 = 8.6, 12,4; 5 = 10.6, 14.4). Ration specific reactions could only be proved for the parameters glucose and urea out of the metabolites (insulin, glucose, cholesterol, urea tri-iodine thyronine and thyroxine).
