[The effect of different biotechnical measures on live and stillborn piglets of sows of different body condition and parity].
In a single large pig production unit of 6000 breeding sows, seven groups of 100 sows each were formed at random on the 110th day of pregnancy. Each group was evaluated and divided according to body condition in three subgroups. The average parity in each subgroup was recorded. The groups were treated as follows: Group 1 received on the 113th day of pregnancy a 3 mg single intramuscular dose of alfaprostol. Group 2 received on the 113th day of pregnancy a 3 mg single intramuscular dose of alfaprostol, 24 hours later a single intramuscular dose of 10 IU of oxytocin. Group 3 received a single intramuscular dose of 10 IU of oxytocin after the birth of the first piglet. Group 4 received on the 113th day of pregnancy a 100 mg single intramuscular dose of prednisolone. Group 5 received on the 113th day of pregnancy a 0.2 mg single intramuscular dose of carbamylcholine. Group 6 received from the 110th day of pregnancy food consisting of 12% fiber, 3 kg per sow per day. Group 7 (control) received a 3 ml physiologic NaCl solution on the 114th day of pregnancy. The following parameter were evaluated: A: Number of live born piglets B: Number of intrapartum stillborn piglets As regard number of live born piglets no significant difference was seen between the experimental groups (1-6) and the control group (7). On the other hand showed the experimental group 1, 2, 5 and 6 significant lower incidence of intrapartum stillbirth when compared to the control (group 7). Within the groups the tendency was seen, that the sows with higher parity and body condition produced less numbers of live born and higher numbers of intrapartum stillborn piglets.
