Adult mortality rates in Leghorn X Red reciprocal crosses at three North Central stations [Chickens, United States]

Adult mortality rates in Leghorn X Red reciprocal crosses at three North Central stations [Chickens, United States]

Adult mortality rates among progeny of Leghorn X Red reciprocal crosses were observed concurrently at three North Central Region experiment stations. Female mortality rates were significantly (P less than or equal to .05) higher at all locations among progeny of the Leghorn male parent. Male mortali...

Zusammenfassung:Adult mortality rates among progeny of Leghorn X Red reciprocal crosses were observed concurrently at three North Central Region experiment stations. Female mortality rates were significantly (P less than or equal to .05) higher at all locations among progeny of the Leghorn male parent. Male mortality rates (observed at two locations) between crosses were not different and thus suggested a sex chromosome involvement with mortality rates in these crosses.
