چکیده

ANNA W. I. VAN DAM-BAKKER AND OTHERS '958 3. The growth rate of young rats, given the high-protein and the low-protein moieties of the diet on alternate days was less than that of pair-fed, litter-mate control animals consuming both moieties together. 4. Intermittent protein feeding likewise impaired lactational capacity of the mothers and retarded recovery of the haemoglobin content of the blood after experimentally induced anaemia. 5 . Fertility was not noticeably affected by intermittent feeding of protein. 6. The less satisfactory condition of the young of the mothers given protein intermittently remained clearly manifest after weaning, when young of both groups were raised on a normal stock diet.

Effect of Different Amounts of Protein and Varying Proportions of Corn Silage and Alfalfa Hay on Milk Production and Nitrogen Excretion of Dairy Holstein Cows

Four treatments were assigned to determine the effects of dietary potential digestible fiber (pdF) and crude protein (CP) levels in mid lactating Holstein cows on milk production and nitrogen efficiency. Sixteen primiparous (n=8) and multiparous (n=8) Holstein cows (body weight (BW)=546±72 kg; days in milk (DIM)=118±50 day) were allocated to one of four diets in balanced randomized complete des...

Blood gases and metabolite content and ruminal fermentation in response to diets with different fermentability in Holstein dairy cows

The objective of this study was to determine the effects of diets having different fermentability on blood gases, blood metabolites and ruminal fermentation parameters in Holstein dairy cows. Four multiparous Holstein dairy cows (665 ± 25 kg BW, 170 ± 7.0 DIM and 15±1.5 kg of milk yield), fitted with rumen cannulae, were used in a 4×4 Latin Square design with 28-d periods. Corn starch and sucro...

Exretion of chromic oxide administered in paper to steers fed prairie hay.

T H E value of chromic oxide (chromium sesquioxide) as an indicator for estimating fecal output of sheep and cattle is dependent upon its concentration at a given sampling time providing the basis for estimating a standard recovery. However, chromic oxide excretion rate exhibits a diurnal variation (Hardison et al., 1959; Kane, Jacobson and Moore, 1952) which apparently precludes choosing a des...
