Grain Storage Facilities [This Month in Ag Connection] [Ag Connection - Other Issues Online] Nutrition And Reproductive Management For Replacement Gilts Modern sows are larger in mature body size, leaner, have increased milk production and continue to increase lean mass through their second or third parity (litters). These increased nutrient requirements for maintenance, lean growth and milk production requires specialized nutrition and management program for replacement gilts. In addition to feeding regimes, gilt development programs must manage the health and maturation of replacement gilts to allow for optimum growth, development, reproductive performance, weaning weights, and sow longevity. Nutrition for Developing Gilts Proper nutrition allows developing gilts to express their genetic potential in traits mentioned above. Finishing diets are adequate in nutrition until replacement females reach 180-200 pounds. Vitamin and mineral levels for gilt development need to be increased to match sow gestation diets. These diets should be formulated to contain higher levels of calcium, phosphorous, biotin, folic acid, and choline, than generally contained in finishing diets. Rations containing adequate vitamin and mineral levels help ensure proper bone growth and structural development. Gilts should reach a body weight of 270 -
320 pounds at 210 - 240 days of age. From 180 to 280 pounds, they should
be full-fed a diet that will allow bodyweight gain of 1.5 –1.7 pounds
per day. Expected daily feed intake should be 5 to 7 pounds per head.
Manage the rate of gain by adjusting the feeding rate and/or energy
level of the diet. Gilts that are full-fed during development may over
consume feed, resulting in excess body condition and weight in breeding.
Adding high fiber, low energy ingredients to the diet, will reduce its
energy level. Wheat middlings, soy hulls, alfalfa meal, or beet pulp are
examples of acceptable ingredients. These diets should contain nutrient
levels within the ranges presented in Table 1.

If gilts are limit fed, they should be
returned to full feed three weeks prior to mating. Gilts on a high level
of nutrition should have an increased ovulation rate. Increasing energy intake during lactation will minimize weight and backfat loss, but has marginal effects on piglet growth and subsequent reproductive performance. Amino acid intake during the first lactation can have dramatic impacts on weaning weight, days to estrus, and on the subsequent reproductive performance. Replacement gilts will comprise 10 – 20% of a farrowing group when they are moved into the normal production cycle. Often, it is only feasible to use one lactation diet, in which case a top dress needs to be fed. Crating gilts in one area of the farrowing room makes topdressing more time efficient. The result of these efforts will be to reduce second parity performance dip. In the properly fed and developed first
parity female, milk production will reach near maximum levels the first
week after farrowing. Feeding in the farrowing house should be managed
to increase feed intake rapidly after parturition. An example-feeding
schedule is outlined below.
This feeding schedule allows for full feeding by day. If feed remains in the feeder, the gilt is not fed until the subsequent feeding. If feed remains the following morning the feeder should be emptied and fresh feed supplied. It is not recommended to feed more than 6 pounds at any one feeding. This method simplifies the feeding process and allows the feeding management to be easily tailored to fit the individual gilt. The goal of the gilt-feeding program is to maximize intake the first week after farrowing. If maximum intake is not achieved until day 14, the gilt will have already begun to catabolize body tissues and significant body muscle and fat breakdown will have occurred between the seventh and fourteenth day. Proper management of gilt nutrition through the first parity can have a dramatic effect on both short and long term productivity. Knowledge of the average daily feed consumption in lactation should be used to modify diets in order to assure adequate nutrient intake to support maintenance, growth and milk production of first parity females.

Many commercial first aid kits are available. At least a small, regularly maintained kit on should be kept on every major piece of farm equipment, truck, or auto. Display a larger kit in each farm building, shop, or home. A larger first aid kit should include:
Most commercial first aid kits do not address the farm needs for pesticide application. Make your own first aid kit using a sturdy box with a tight-fitting cover that can be securely latched. Tackle or toolboxes are a good choice. Store the kit where it will not become contaminated by pesticides. Label all containers clearly. Use a waterproof marker or nail polish to label plastic bottles. You should include the following items in your pesticide first aid kit:

The spreadsheet allows the producer to pick out specific breeding dates to print a “barn sheet”. These barn sheets are especially helpful when multiple people are involved in the operation.
