Description:
Sixteen hours of light daily (114 to 207 lux) increased weight gains and milk yield 10 to 15% in Holstein cattle in comparison with cattle exposed to natural-length photoperiods (39 to 93 lux) of 9 to 12 hours. The weight gain was accomplished without increased consumption of feed. Manipulation of supplemental light may thus cause dramatic increases in food supplies from animals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peters, R R -- Chapin, L T -- Leining, K B -- Tucker, H A -- New York, N.Y. -- Science. 1978 Feb 24;199(4331):911-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/622576" target="_blank"〉PubMed〈/a〉
