各階段豬只的正常采食量表和肥育豬生產(chǎn)成本計算：按豬的體重計算喂量=實際體重×系數(shù)，系數(shù)為小豬0.05，中豬0.04，大豬0.03，這套系數(shù)也要牢記住，即豬的采食量系數(shù)。 或按下表參考進行喂量的選擇：表：豬在不同生長階段的采食量(體重：千克;日喂量：克;日齡：天)
從上表可知道：⑴ 乳豬從開食到改用小豬飼料的7～50日齡期間：共消耗教槽料5.8千克，乳豬飼料15.28千克。⑵ 小豬從50日齡到87日齡(15～35公斤重階段)共消耗小豬飼料：35.65千克。⑶ 中豬從87日齡到125日齡(35～65公斤體重階段)共消耗中豬飼料：80.8千克。⑷ 大豬從125日齡到168日齡(65～108公斤體重階段)共消耗大豬飼料：118.8千克。⑸ 中小型豬場以一頭母豬年產(chǎn)20頭仔豬的保守估計來計算成本，一頭母豬年消耗飼料1100千克，母豬飼料成本主要為妊娠母豬飼料和哺乳母豬飼料，平均一下價格為：2.56元/千克，所以，一頭母豬年飼料成本：1100×2.56=2816元，加上藥物免疫和人工成本484元，則一共為3300元。 另外，購置母豬時的成本一般為1800元，至于購置成本，則淘汰母豬可以出售，也大約就是1800元，母豬目前可以按國家有關規(guī)定進行銷售，所以，購置成本可以用這項收入來抵消。剛引進的后備母豬約4月齡，需要繼續(xù)飼養(yǎng)3個月才能配種，這中間消耗后備母豬飼料240千克，成本為：240×2.49=598元，加上期間的藥費42元，運輸和人工200元，共840元，以后進入生產(chǎn)期成本計算期，生產(chǎn)期大約為5年(中小型豬場護理得好，可以達到五年使用期限)，則每年攤?cè)牒髠淠肛i飼養(yǎng)成本840÷5=168元。所以，母豬一年的成本為3300+168=3468元。 由此可以計算出每頭初生仔豬(含喂養(yǎng)它的奶水)的成本為3468÷20=173元。每頭肥育豬到出欄時的總成本計算表：千克、元/千克、元/頭。
注：其中飼料價格見文章最后的飼料配方表，即：小豬料2600元/噸，中豬料2490元/噸，大豬料2400元/噸，妊娠母豬料2420元/噸，哺乳母豬2690元/噸，后備母豬料2490元/噸，① 由上表可知：養(yǎng)出一頭30斤以上的仔豬的成本為173+46.4+91.68=311元。② 由表可知：一頭肥育豬總生產(chǎn)成本為：80+890=970元/頭。③ 純利潤計算： 按現(xiàn)在的行情：生豬價格15元/公斤，則養(yǎng)到108公斤生豬出售收入為：1620元。 純利潤為：1620-970=650元/頭。 如果采用微生態(tài)技術(shù)，發(fā)酵技術(shù)，增強豬只抗病力，中小型豬場的精細化管理，和照顧豬只福利的新技術(shù)(如活動場、發(fā)酵床技術(shù)、夏天降溫得力措施，冬天保暖措施等)，則降低豬只死亡率和得病率，可以減少這方面的成本約40元，同時，母豬年產(chǎn)仔可以增加到24頭，可減少每頭的成本約30元，另外，飼養(yǎng)到120公斤出欄，每頭可以再增加利潤約90元，所以，加強管理和養(yǎng)到120公斤重可以再產(chǎn)加總利潤：160元，這樣每頭總利潤可達到810元，這里指的是純利潤。④ 料肉比計算：由表可知： 從15公斤到108公斤階段的育肥階段的料肉比為(35.65+80.8+118.8)÷(108-15)=2.53， 如果是從斷奶(28日齡開始)到108公斤階段，則料肉比為：(15.28+35.65+80.8+118.8)÷(108-8)=2.50。 從8到15公斤料肉比為1.42。
The English version
Pigs in each stage of the normal intake of tables and fattening pig production cost calculation: calculated based on weight of pig feed quantity x = actual weight coefficient, coefficient is 0.05 the pig, middle pig 0.04, 0.03, big pig this coefficient also remember to live, the pig feed intake coefficient. Or the choice of feeding amount according to the table below the reference: table: pigs in different growth stages of feed intake (weight: kg; daily feeding amount: g; day age:)
From the table above can know: (1) Suckling pig feed from the open to the use of pig feed during 7 ~ 50 days of age: total consumption teach slot is 5.8 kg, Suckling pig feed 15.28 kg. 2 pigs from 50 to 87 days of age day age phase (15 ~ 35 kilograms), a total of pig feed consumption: 35.65 kg. (3) middle pig day age from 87 to 125 days of age (35 to 65 kg) were middle pig feed consumption: 80.8 kg. (4) big pig day age from 125 to 168 days of age phase (65 ~ 108 kilogram of body weight), a total of consumption big pig feed: 118.8 kg. 5] small and medium-sized pig farms with one sows a conservative estimate of the annual output of 20 head piglets to calculate the cost of a head of the sow feed consumption 1100 kilograms, the sow feed costs mainly sow feed for pregnancy and lactation sow feed, the average price for: 2.56 yuan/kg, so, a head of the sow feed costs: 1100 * 2.56 = 2816 yuan, plus drugs immune and artificial cost 484 yuan, a total of 3300 yuan. In addition, when purchasing sows typically cost is 1800 yuan, as for the acquisition cost, has eliminated the sow can sell, is about 1800 yuan, also can sow now according to the relevant provisions of the state, so the cost can be used to offset the income. Introduced the gilt about 4 months of age, the need to continue to raise 3 months before breeding, the consumption among the gilt feed 240 kilograms, cost is: 240 * 2.49 = 598 yuan, plus the drug during the 42 yuan, transportation and artificial 200 yuan, a total of 840 yuan, after going into production period cost calculation, production period is about 5 years (small and medium-sized pig care good, can achieve five years life), would stand a year in the gilt breeding cost present 5 = $840 to $168. So, sow a year cost is RMB 3300 + 168 = 168. Thus can calculate each newborn piglets (including feed it milk) cost is RMB 3468 present 20 = 173. Every fattening pig are: in the total cost of the calculation table, yuan/grams, yuan/head.
Note: the table feed prices see article last the feed formulation, namely: the pig is expected to 2600 yuan/ton, middle pig is expected to 2490 yuan/ton, big pig is expected to 2400 yuan/ton, the pregnancy sow is expected to 2420 yuan/ton, 2690 yuan/ton, lactation sows the gilt is expected to 2490 yuan/ton, (1) by above knowable, raise the cost of a head of 30 kilograms of piglets is 173 + 46.4 + 46.4 = 311 yuan. (2) the table shows: a fattening pig total production cost is: 80 + 890 = 80 yuan per head. (3) net profit calculation: according to the current market: pig price 15 yuan/kg, is to raise pig sale income to 108 kg for: 1620 yuan. Net profit is: 1620-970 = 650 yuan/head. If using micro ecological technology, fermentation technology, enhance pig disease resistance, small and medium-sized pig farms of fine management, new technology and the welfare of the pigs (field, such as fermentation bed technology, summer cooling effective measures, winter heat preservation measures, etc.), the pig mortality and disease rate, can reduce the cost of about 40 yuan, at the same time, the sow in litter can be increased to 24, may help reduce costs about $30 per head, in addition, feeding to 120 kg market, every head can increase the profit of about 90 dollars, so, to strengthen management and raise to 120 kg can produce aggregated profits: 160 yuan, so that each may reach 810 yuan, total profits here refers to the net profit. (4) feed conversion ratio calculation: the table shows: the fattening phase, the phase from 15 kg to 108 kg of feed conversion ratio of (35.65 + 80.8 + 118.8) present (108-15) = 2.53, if from weaning stage (28 days of age) to 108 kg, the feed conversion ratio is: (15.28 + 35.65 + 80.8 + 15.28) present (108-8) = 2.50. From 8 to 15 kg feed conversion ratio of 1.42.
