 The objectives for the sow herd are to maximize profitable production of healthy pigs and to prolong the efficient productive lifetime of the sow. Maternal lines have been developed with very high rates of reproductive potential. These lean genotypes have body compositions with a large amount of muscle mass and low fat reserves. Because of larger litter sizes in today’s prolific gilts and sows, these females are vulnerable to weight loss in lactation and potentially high replacement rates if not fed and managed properly. Greater outputs from the sow require greater nutrient input if the genetic potential is to be realized for any length of time. Feeding strategies for today’s top-performing sows must match nutrient requirements and sustain sows under intensive production systems.
To achieve the full reproductive potential of any sow, it is necessary to consider the whole breeding cycle beginning with the young prepubertal gilt. All phases of the sow’s reproductive cycle are interrelated. Nutritional status of the gestating sow has a profound effect on lactation performance and post-weaned breeding performance. Akey’s gilt and sow feeding programs are formulated to support high milk production in modern genotypes and promote efficient rebreeding and longevity of the sow. |
