    Gilts are young females that have not yet farrowed, that is to say given birth, to their first litter of piglets. The first litter is always a learning experience for a new mother and first litters tend to be smaller than subsequent litters. Thus gilts are less expensive than Effect of Feed Intake During the Weaning to Remaining Interval on the Reproductive Performance of Gilts and Sows Nutrient Requirements of Developing Boars ( kg) Energy Requirements of Working Boars

    Value in this application was found on a farm employing a program for estrus synchronization and ovulation with fixed time insemination. When assessing ovarian structures, approximately 4% of the sows were being bred while having a functional CL present. These sows, subsequently, developed a Late Spring Farrow. The management of mature sows in the pro- duction of late spring pigs was definitely less efficient on the farms in this study than the management of gilts, when measured by the net cost of the pigs produced. The cost of maintaining mature sows was markedly higher than the cost of maintaining

The results are reported of an extensive experiment to determine the value of mature sows, gilts from mature sows, and gilts from gilts for producing market hogs.

It was found that pigs could be more economically reared to market weight of about lb. if they were farrowed by gilts, the progeny of either mature sows or of gilts. Gilts required less feeding during the gestation period and Additional Physical Format: Online version: Russell, E.

(Ellsworth Zouave), Comparative value of mature sows and gilts for producing market :// These need to be evaluated to minimize the post weaning growth check. Approximately, 75% of feed is fed in the grower-finisher phase of production which constitutes roughly 65%–75% of the total cost of producing market hogs.

3 Feed wastage could be a challenge at this period. Feeder design and adjustments are therefore critical at this :// Sows. See also what's at Wikipedia, your library, or elsewhere. Broader terms: Swine; Female livestock; Used for: Gilts; Filed under: Sows.

Gilts Selection. Gilts of the appropriate genotype that have 12 to 14 teats should be selected from the sows with the best reproductive performance. In addition, research has demonstrated that gilts reared in smaller litters (≤ 7) have greater reproductive performance than gilts reared in large litters (≥ 10).

The NRC () recommendations are considerably lower than the voluntary daily intakes of to 18 Mcal of DE observed by Friend () for bred gilts and sows. Vol- untary intake of energy declined from mating to farrow- ing at a rate of kcal/day for gilts and a rate of kcal/day for sows Bred Gilts and Sows.

Mature bred sows require little more than a maintenance diet during the first 90 days of gestation. During the last days of gestation, rapid growth of the developing litter demands extra nutrients.

One of the most valued of assets on the farm today is the brood sow and the expectancy of her litter. It is therefore necessary that due attention be given this and every other sow in order that she will produce the greatest number of pigs of the best Over a 3-year period,the breed- ing herd, consisting of gilts, sows and boars, averaged (SDrange ) in this group and clean-up was achieved in an average of months (SDrange ).

Introduction. Porcine proliferative enteropathy (PPE) is an important enteric disease in swine herds throughout the world. Disease is caused by the intracellular bacterium Lawsonia intracellularis, which infects enterocytes mainly in the distal part of the ileum ().Porcine proliferative enteropathy is known to occur in acute and chronic forms (1,2).
