The objectives for good gilt management and nutrition should be to optimize reproductive productivity and longevity. Gilts should be from large litters, not be splay legged, and have at least 6 functional teats on each side. In the nursery, feed intake should be stimulated by way of gruel feed (often and little) or pellets. The diet should be palatable, highly digestible and should be a little bit higher quality than for the other pigs. Do not crowd and run it as all-in-all-out. Use quality floor to avoid leg injuries. In the finisher phase, gilts should be fed gilt diets high in amino acids, calcium, and available phosphorus. There is no correlation between rate of growth and age at puberty, but excessive nutrients is not economically efficient. Strict selection criteria should be followed. Leg structure is very important because poor legs can lead to sows with poor movement and early culling. It is a waste to have a perfectly good reproductive sow that cannot walk. Body weight should be equally distributed on 8 toes. Gilts that take short steps and walk on their toes should not be selected. Each foot should have 2 even sized toes for balance. Large bones are desirable, but should have a normal structure to them. Gilts should be 135 kg with 16 mm of back fat at the time of first breeding. Stress, relocation, and mixing should be avoided to avoid a reduction in feed intake. 10 to 12 hours of light per day at 270 to 500 lux intensity should be provided. Non-genetic factors such as feed intake, lean tissue growth rate, nutrition, stocking density, and air quality have the largest effect on the onset of puberty. By far the most effective factor is good boar stimulation. This can reduce age to puberty by 3 to 4 weeks. Boar must be at least 10 months old and have nose-to-nose contact with the gilts for 20 minutes per day. The boar should not be overworked. Breeding on the second estrus can give an additional 0.83 pigs and is important to prevent premature culling. Gilts should be \u00e2\u20ac\u0153flushed\u00e2\u20ac\u009d (fed ad lib) for 2 weeks prior to first breeding to increase ovulation rate.<\/p>\n","protected":false},"excerpt":{"rendered":"
