The Influence of Growth Hormone Gene Polymorphism on Growth Rate of Young Cattle
Beef production is an important development area in animal breeding with meat quality being determined by both paratypic and genetic factors. In this regard evaluating genetic material for the presence of desirable allele combinations of genes associated with growth and development indicators, as well as meat qualities of animals have a certain scientific and practical significance. The aim of ...
متن کاملAltered feathering of chicks caused by T-2 toxin.
Dietary T-2 toxin (0, 1, 2, 4, 8, and 16 mug./g.) was fed to 4 groups of 10 chickens at each treatment level from hatching until 3 weeks of age. Growth inhibitory levels (4, 8, and 16 mug./g.) caused abnormal feathering which appeared dose related. The chickens were sparsely covered with short feathers protruding at odd angles in comparison to controls. There were few feathers on the base of th...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Does growth rate determine the rate of metabolism in shorebird chicks living in the Arctic?
We measured resting and peak metabolic rates (RMR and PMR, respectively) during development of chicks of seven species of shorebirds: least sandpiper (Calidris minutilla; adult mass 20-22 g), dunlin (Calidris alpina; 56-62 g), lesser yellowlegs (Tringa flavipes; 88-92 g), short-billed dowitcher (Limnodromus griseus; 85-112 g), lesser golden plover (Pluvialis dominicana; 150-156 g), Hudsonian go...
متن کاملThe Influence of Oxygen Tension upon Metabolic Rate in Invertebrates
It is shown that in several of the higher invertebrate animals, oxygen consumption is directly proportional to the oxygen tension in the sea water, over a wide range.
