Human Metapneumovirus in Turkey Poults

متن کاملSegregation of two alleles for color of down in parthenogenetic and normal turkey embryos and poults.
Data were collected on the down color of 1,386 parthenogenetic embryos and poults from eggs of 306 young virgin and older nonmated bronze turkey hens. Each hen involved was heterozygous (Cc) for alleles which affect feather pigmentation. Six hundred and sixty nine white and 717 colored parthenogenetic embryos and poults were observed, a 1:1 ratio. Subsequently, 89 of these 306 heterozygous bron...

Histological changes in the intestine have been described (Adams, Ball and Hofstad, 1970), including shortened microvilli, slight oedema, a decrease in argentafhn cells and an increase followed by a decrea...
متن کاملEnergy utilization in newly hatched chicks.
The changes in body weight and composition were examined in broilers that either had immediate access to feed and water or had not been fed for 48 h posthatch. Chicks without access to feed decreased in BW by 7.8% in the 48 h posthatch, which was equivalent to 5.3 kcal/45 g chick/d. However, during this period the small intestines increased in weight and protein content by 80% or more. The decr...
