Online resources: Abstract: Herman R. Valero, University of the Philippines at Los Banos, May 1980. The Effects of Two Dietary Levels of Protein and Two Systems of Housing Management on the Growth Twenty-four crossbred (Holstein x Red Sindhi) yearling calves were used in a 2 x 2 factorial in a randomized complete block design (RCBD), to determine the effects of two protein levels (14 percent and 16 percent crude protein (CP)) and two systems of housing management (indoor and outdoor) an the growth and performance of dairy calves. The results showed that calves fed the ration with 16 percent CP consumed significantly more protein (P/.01) and dry matter (P/.05) than those fed with 14 percent CP. Likewise, the sane group of calves consumed more calf ration. However, the protein levels and systems of housing management did not show significant (P<05) effects on calves roughage intake, daily liveweight gain, height at wither, heart girth, body length and physiological responses. No significant (P<05) differences were observed an total cost and daily cost of feeding. Similarly, the cost of feeding to produce a liveweight gain as affected by two protein levels and two systems of housing management is not significant. Furthermore; adoption of feeding salves ration with 16 percent CP coupled with outdoor system of housing management is profitable as compared to the rest of the treatment combination studied, because it involved the least cost to produce a kilo of liveweight gain and higher weight gain

Twenty-four crossbred (Holstein x Red Sindhi) yearling calves were used in a 2 x 2 factorial in a randomized complete block design (RCBD), to determine the effects of two protein levels (14 percent and 16 percent crude protein (CP)) and two systems of housing management (indoor and outdoor) an the growth and performance of dairy calves.
The results showed that calves fed the ration with 16 percent CP consumed significantly more protein (P/.01) and dry matter (P/.05) than those fed with 14 percent CP. Likewise, the sane group of calves consumed more calf ration. However, the protein levels and systems of housing management did not show significant (P<05) effects on calves roughage intake, daily liveweight gain, height at wither, heart girth, body length and physiological responses. No significant (P<05) differences were observed an total cost and daily cost of feeding. Similarly, the cost of feeding to produce a liveweight gain as affected by two protein levels and two systems of housing management is not significant.
Furthermore; adoption of feeding salves ration with 16 percent CP coupled with outdoor system of housing management is profitable as compared to the rest of the treatment combination studied, because it involved the least cost to produce a kilo of liveweight gain and higher weight gain
