Hello there from Warsaw today. I enjoyed reading this paper so much, many thanks Prf. Hurley. I did part of my practical period at Wageningen University and later on in my previous company with sows, pregnant and lactating animals. The raising of a whole litter by a sow is a miracle of biology; how amazing is that an animal can produce >10 liters of milk per day to grow its litter?. Well much of the explanation is expressed in this great paper and together with this the skills of nutritionists and stockmen to formulate feeds which will provide the nutrients enough allowing the sow to maintain body condition - not an easy one! - and look after these great females. Greetings and thanks again, Rafa.
