The relation between the quality of meat and feed in chick
Nihon Chikusan Gakkaiho, 1955 動物性又は植物性基礎飼料に,Penicillin, Vitamin B12又は肝臓粉を加えた飼料を用い90日間の試験に於て増体量は動物性飼料にPenicillin 1/10万量,V.B1220γ及び肝臓粉5%を加えたるものが最も大にして肉量も多く肉質も良好である。而して動物性飼料と植物性飼料を比較すれば魚粉10%配合した動物性飼料が植物性飼料よりも肉量多く肉質も良い事が認められた。(附記) この研究は文部省科学研究助成補助金によるものである。この実験を遂行するに当り東大教授佐々木林治郎先生の御指導と森本博士及び有吉技官の御助言のあったことを記し感謝の意を表する。

Nutritional Qualities of Stabilized and Raw Rice Bran for Chicks
Poultry Science, 1987 Rice bran either raw or processed in an extrusion cooker at 130 C was fed to meat strain chickens for 25 days after hatch. Either full fat or hexane-extracted rice bran was placed in the diet at the equivalent of 60% full fat bran. Raw full fat bran for one diet was stored at -23 C until fed, whereas rice bran for all other diets was stored at 32 C ...

Prospects for transgenesis in the chick [PDF]
, 2004 Research to develop a useful method for genetic modification of the chick has been on-going since the first demonstrations in the mouse in the 1980s that genetic modification is an invaluable tool for the study of gene function. Manipulation of the chick

Journal of Applied Poultry Research, 2004 SUMMARY Nutritional and environmental conditions influence broiler flock performance. Besides these factors, other less-well-understood factors, such as incubating egg characteristics, affect the embryonic life of chicks. This study demonstrated that egg storage depressed egg albumen Haugh units (HU) and chick quality; these effects of storage were ...

Comparative analysis of hatcheries contribution to poor development of day-old chicks based on biological and immunological performance [PDF]
Veterinary World, 2019 Background and Aim: The quality of day-old chicks is a cornerstone to successful poultry production. Chicks with a poor quality start slowly in the field and may have high feed intake, poor growth rate, and poor feed conversion ratio.

The chicken embryo and its micro environment during egg storage and early incubation [PDF]
, 2008 When egg storage periods are prolonged (>7 days), hatchability and chick quality declines. The reason for this decline has been investigated, but is still not completely understood.
