The nitrogen requirement of the weanling kitten.
The nitrogen requirement of the weanling kitten was determined in a series of three experiments. In each experiment, diets were formulated to provide the growing kitten with the essential amino acids at or above the level of requirement. Expt 1 utilized a 4 x 4 balanced Latin square design with two groups of kittens (four male and four female). The crystalline L-amino acid diets were presented ...
متن کاملQuantitative study of cortical orientation selectivity in visually inexperienced kitten.
1. Extracellular recordings were made from single units in the visual cortices of six kittens deprived of experience with pattern vision by binocular lid suture. 2. Selectivity for stimulus orientation was quantitatively assessed in 98 units; 90 responded selectively to the orientation of a moving bar stimulus, the remainder responding nonselectively or too poorly to classify. Cells in these vi...
متن کاملThe tryptophan requirement of the kitten.
To estimate the tryptophan requirement of the kitten, six male and six female kittens were presented diets containing 0.7, 0.9, 1.1, 1.3, 1.5 and 3.0 g tryptophan/kg diet for six experimental periods lasting 10 d in accordance with a 6 X 6 balanced Latin-square design. Mean daily weight gain and nitrogen retention (N intake minus urinary and faecal N) plateaued at 1.1 g tryptophan/kg diet indic...
متن کاملLeucine and isoleucine requirements of the kitten.
In separate experiments the isoleucine and leucine requirements of the kitten were determined on the basis of growth and nitrogen retention. The dietary concentrations of isoleucine tested were (g/kg diet) 1.4, 2.2, 3.0, 3.8, 4.6 and 9.0 with adequate (12.0 g/kg diet) leucine. The levels of leucine tested were (g/kg diet) 5.0, 7.5, 9.0, 10.5, 12.0 and 20.0 in diets containing adequate (9.0 g/kg...
متن کاملPostnatal neurogenesis in the kitten retina.
Postnatal neurogenesis in the kitten retina was studied using 3H-thymidine radioautography. Kittens were injected with 3H-thymidine at 1 day, 10 days, 3 weeks or 4 weeks after birth and allowed to survive until 14 weeks of age. Labeled neuronal nuclei were not found in the ganglion cell layer in any of the retinas, but they were seen in the other nuclear layers of the same retinas. In retinas f...
