Heavier nursery pigs generally means heavier market pigs 出保育欄體重大通常預(yù)示出欄是體重也大 ? 1 kg nursery weight ≈ 34 kg market weight. 1公斤保育欄體重大約等于 3到 4公斤上市體重 . ? 295 gram heavier weight at the end of the nursery period may translate to – kg heavier pig at market or fewer days to market. 額外 295克保育欄體重相當(dāng)于 到 市體重或者節(jié)省幾天飼喂時(shí)間 .
