1. Studies on the effect of supplementing copper and cobalt were conducted in 4- to 10-month-old dairy calves during successive indoor and outdoor feeding periods on conserved forges and fresh pastures respectively. 2. No significant differences in live-weight gains or serum Cu were recorded during the indoor period of 40 d. 3. Both live-weight gains and serum Cu were significantly elevated (P < 0.05) by Cu supplementation during the following grazing period of 70 d. 4. Supplementation with Co… 

Effects of Short-Term Over-supplementation of Copper in Milk on Hematology, Serum Proteins, Weight Gain, and Health in Dairy Calves

Age (sampling time) had significant effects on the values of most measured parameters (p < 0.05) except WBC, lymphocyte, total protein, and fibrinogen, which were significantly lower in test 1 group than other trial groups.

Effects of cobalt and copper supplementation on vitamin B 12 status and blood parameters in lambs

Vitamin B12 production by rumen microorganism was accounted for by cobalt intake with no collaborate effects of Co plus Cu supplied in the diet and Haeme-depending blood parameters were enhanced by Co or Cu supplementation.

Trace mineral contents of grass and browses in Tanzania and its implication to ruminant feeding and reproduction

Se, Zn and Cu contained in pastures were below ruminants’ requirements for reproduction, thus, supplementation of such trace minerals is inevitable if optimal reproduction is desired.

Feeding Sheep Cobalt and Oregano Essential Oil Alone or in Combination on Ruminal Nutrient Digestibility, Fermentation, and Fiber Digestion Combined With Scanning Electron Microscopy

Results demonstrated that feeding Co, EO, or EOC at 4 or 7 g/day enhanced ruminal nutrient digestion and fermentation parameters, which was visually confirmed via SEM and SM.

Mineral concentrations in leaves of nine browse species collected from Mvomero, Morogoro, Tanzania

Mineral contents in browse leaves and concentrations of nutrients available in soil at the end of rain season were determined in Mvomero District, Morogoro, Tanzania. Nine species, namely Accacia

It is difficult to determine precise dietary copper requirements and to predict potentially toxic levels of copper for ruminants under different feeding programs because of the many factors influencing copper metabolism.

An investigation into copper deficiency in cattle in the Southern Pennines. II. Response to copper supplementation

SUMMARY Copper supplementation within the molybdenum-rich areas, on an exploratory basis in 1967 and in controlled trials in 1968, showed mean live-weight responses of 10–70% in dairy followers

It is suggested that variations in dietary S and Mo within the normal range for herbage affect the Cu and Mo metabolism of the grazing animal, and that total S rather than inorganic S is the more useful measurement in the context of the Cu-Mo-S interrelationship.

The Occurrence of Conditioned and Simple Copper Deficiency in Cattle and Sheep in Setesdalen, a Valley in the Southern Part of Norway II

It was found that the content of both molybdenum and copper increased during the summer and reached its highest values in the first part of August, and the results of the analyses give no support for sulphur as a conditioning factor in Setesdalen.

Changes in adipose tissue of the rat due to early undernutrition followed by rehabilitation

There were no significant differences in apparent or total fat cell numbers between ad lib.-fed animals and undernourished-rehabilitated animals at any of the four sites studied at 32 weeks of age.

Deposition of fat in the body of the rat during rehabilitation after early undernutrition

The previously undernourished rats deposited significantly more fat in their bodies during rehabilitation than the control animals in the same number of days and over the same gain in body-weight.

Changes in adipose tissue of the rat due to early undernutrition followed by rehabilitation

Animals reared in litters of sixteen and further undernourished from 3 to 12 weeks (group L16/U) had significantly fewer fat cells at all sites studied than animals rearing in Litters of three and ad lib.-fed.
