家禽产值的计算方法有两种,一种是一般可按各种家禽的年末只数乘以成年家禽单价计算”。另一种是“某些地区如条件许可,也可按更准确的公式计算”,该公式为:某种家食年末年初本年屠本年调(卖)本年调(买)×单价饲养产值=只数只数+宰数+出只数入只数现在,还有人主张“按年内平均饲养头数乘单价的办法来计算家禽产值”。用年末饲养只数或年平均饲养只数来计算家禽饲养产值,方法简便,但计算结果却不很准确。用上文所述公式来计算家禽饲养产值,则有可能出现年净增饲养只数为负的情况,而这一负数又正好是家禽的死亡只数．下面以我场第一养鸡场lop年的实际数字为例,看一看用公式确定的计算产值的家禽只数。第一养鸡场 1990年年初存栏 129470只,购入 66 154只,转入 186647只,卖出 72 467只,转出 186 647只,年末存栏89 098只,死亡34 059只。按公式计算的家禽饲养只数为:
There are two ways to calculate the value of poultry production, one is the general calculation of the number of poultry at the year-end multiplied by the unit price of adult poultry. “The other is that” in some areas, if the conditions permit, it can also be calculated according to a more accurate formula This formula is: Some kind of food The year-end and New Year this year Tu Tuenian year (Sell) The current transfer (Buy) × unit price Feeding output = the number of only + the number of + the number of only counted into the number Now, there are people who advocate “ According to the average number of rearing units by year to calculate the unit price of poultry production value. ”Use the end of the year feeding only or the average number of rearing to calculate the value of poultry production, the method is simple, but the calculation results are not very accurate. Using the formula To calculate the output value of poultry farming, there may be a year net increase in the number of negative cases, and this negative number is exactly the number of poultry deaths below the actual number of our first farm lop years as an example , Take a look at the number of poultry that is calculated by the formula and calculate the output value of the first chicken farm in early 1990, 129,470, purchased 66 154, transferred to 186,647, sold 72,467, 186,647, At the end of the year, 89,098 were kept and 34,059 dead, according to the formula for poultry Keep only number:
