The starter is fed for the first ten days, the grower from day eleven to day twenty-four, and the finisher until slaughter. Management wants to lower feed cost and there is a proposal on the table: split the finisher period in two. The question looks simple, but the answer depends on many things, from the number of bins at the mill to how feed is ordered on the farm.",{"h2":7},"The logic of phase feeding",{"p":9},"As a broiler grows, its daily feed intake rises but the amount of amino acids it needs per kilogram of feed falls. In the first weeks it needs a dense feed for fast muscle growth. Later, a larger share of growth goes into fat and maintenance. Feeding one diet for the whole cycle means either too little at the start or too much at the end. Too much is expensive and too little costs performance.",{"p":11},"With more phases, each feed is made closer to the needs of its period. In theory the best programme is a different feed every day. Nobody does that in practice, because every new feed means a separate formula, a separate production batch and a separate bin at the mill, and a separate delivery on the farm. The right number of phases is a balance between the nutrient saving and the operating cost.",{"h2":13},"Running the numbers on a fourth phase",{"p":15},"Take an example, with illustrative numbers. A broiler slaughtered at day forty-two eats about 4.2 kg of feed over the whole cycle. About 2.6 kg of that is eaten in the finisher period after day twenty-five. Split the finisher into days twenty-five to thirty-four and thirty-five to forty-two, and assume each part accounts for about 1.3 kg per bird.",{"p":17},"The second finisher is solved for a lower level of digestible lysine and the other amino acids. In our example digestible lysine drops by about 0.08 points and the formula is about 250 TRY a tonne cheaper. The saving per bird is 1.3 kg × 0.25 TRY, about 0.33 TRY. In a house of forty thousand birds that is about 13,000 TRY per flock. For a company with ten houses growing six flocks a year, the figure becomes a serious amount.",{"p":19},"There is another side to the calculation, though. The mill needs one more bin, the production plan needs one more feed and the farm needs one more feed change. If the farm's feed bin is too small to take a fourth feed, the two feeds can mix during the change, or the wrong feed can end up on the wrong day. These risks and costs have to be weighed honestly against the saving above.",{"p":21},"There is one more small but important detail on the farm side: emptying the feed bin. You need to know how much of the old feed is left at the bottom of the bin before the new feed arrives. Otherwise the two finishers are fed mixed for days and the phase programme on paper is never applied in the house. Planning deliveries around bin capacity and daily intake is a precondition for keeping the saving from a fourth phase.",{"h2":23},"Feed amount instead of days",{"p":25},"Phase programmes are usually defined in days, but broilers grow by what they eat, not by the calendar. A hot summer flock and a cool autumn flock do not reach the same weight on the same day. That is why many nutritionists prefer to tie feed changes to the amount of feed eaten per bird. For example, the starter is fed for 250 to 300 grams per bird and the grower for the next 1.2 to 1.5 kg.",{"p":27},"This approach has two benefits. First, every flock gets the right amount of dense feed for its needs. A flock that grows more slowly eats the starter for a few days longer. Second, feed orders are easier to plan. A planner who knows the bird count in a house and the feed budget of each phase can work out directly how much of each feed to order.",{"h2":29},"Feed form and temperature",{"p":31},"Phase feeding is not only about nutrient levels. The starter is usually fed as crumbles or fine granules. In later feeds, pellet quality has a direct effect on intake. A flock fed broken, dusty pellets eats less than a flock fed good pellets. So when changing a formula, keep an eye on the ingredients that affect pellet quality, such as the share of wheat and the fat level.",{"p":33},"Feed intake drops in summer. Some companies try to offset this by raising the energy and amino acid density of the finisher feeds slightly in hot periods. That means running the phase programme with different formulas by season. What matters is that every change is recorded and judged together with flock performance.",{"h2":35},"Thinking about the whole mill",{"p":37},"Adding a phase affects the other feeds at the mill as well. The two finishers share ingredients and draw from the same bins. So when you change the phase programme, it is more accurate to solve the feeds together with every other feed at the mill, against shared stock and capacity limits, than one by one. OptiFormula Premium solves the formulas of a mill together, so you see from the start how much of, say, a limited wheat stock the new phase will pull away from the other feeds.",{"p":39},"There is no answer on the number of phases that fits everyone. A fourth phase brings a worthwhile saving for some companies and needlessly complicates operations for others. The way to the right answer is to work out the saving with your own prices and your own flock data, then sit down with the mill and farm teams and ask whether that saving can be kept in practice.",1794234580189]
