NuFeed (Zeolite) Reduced Ammonia Losses from Manure

Research has shown that NuFeed Clinoptilolite zeolite used in feedlot diets reduces nitrogen
(N) loss from manure, compost and lagoons This study was designed to compare the N loss
from manure of cattle fed a control or experimental diet containing 1.2% NuFeed added in
place of steam flaked corn. The manure was collected fresh, sampled for initial N content and
then stacked and sampled again at days 3, 7, 14, 21 and 28. There were 8 Reps per
treatment and the data is shown in table below.

Effect of Feeding NuFeed/ Zeolite on Manure N Loss
Day Control diet Zeolite Diet
Day3 2.6% 4.6%
Day7 22.0% 6.7%
Day 14 25.3% 6.4%
Day21 28.2% 9.1%
Day28 34.9% 12.8%
At the end of 28-days, the N loss was 34.9% compared to 12.8% N loss from the NuFeed/Zeolite Treatment.

Zeolite manure was higher in Nitrogen and had a greater N: P ratio compared to the control
manure in the plant fertilizer study.

Other Zeolite Performance Trials for Ruminants

According to Quarles (1985), research involving over fifty (50) trials has indicated that adding
clinoptilolite zeolite (NuFeed) to cattle rations and other farm animal’s diets gives a small, but
reproducible, improvement in feed conversion efficiency shown by increased weight gains.
The mode of action may be due to the ion exchange properties or the binding of nitrogenous
compounds with the Zeolite (NuFeed) structure.

Tsitsishvili et al (1983) conducted three replicate experiments feeding rations containing 3, 5,
8 and 10% zeolite (NuFeed) to pigs, sheep and cattle. Cattle fed rations with zeolite
(NuFeed) had average weight gains 5-9% higher than the control animals. The animals also
required 3-5% less feed per unit of weight gain. Zeolite (NuFeed) inclusion did not seem to
influence animal health, digestion or blood composition.

Bagishvi/i (1978) cited by Tsitsishvi/i (1983) found that cattle fed rations containing 5, 8 and
10% Zeolite (NuFeed) had average daily weight gains of 5-8% more than the control animals.
Calves fed a ration containing 3% Zeolite (NuFeed) showed a 6-7% improvement in average
daily weight gain (Garbovenski et al. 1981 cited by Dyer n. d)

Nestorov (1983) described the use of Zeolites (NuFeed) in cattle rations. Thirty steers fed
Carbazin (R), a feed additive containing urea, zeolite (NuFeed) and other minerals, showed
an increase of 131g/day over the control group. In a second trial conducted on 6000 steers,
weight gains were 143 g/day more than the control group. This represented 40kgs extra
weight gained over a 280-day feeding period.

Nestorov (1983) using 22 steers, compared the Zeolite (NuFeed) containing Carbazin
product with a patented urea preparation, “Golden-Pro”, (containing 20% urea and 5%
bentonite). The steers were fed for 127 days on diets equalised for fodder units. The
Carbazin group gained an additional 84 g/day live weight and with a lower feed consumption,
higher nitrogen retention and a better utilisation of fibers, in comparison to the control.
Petunkin et al (1993) report three experiments adding Clinoptilolites (NuFeed) to cattle
rations:

  • Feeding Zeolites (NuFeed) at 6% of the ration to young bull caves resulted in additional
    weight gains of 7.5% to 18% and feed conversion was improved by 3.9%-7%.
  • A trial using a different Natural Zeolite (NuFeed) increased live weight gain by 2.4-3.7%
    when fed to bull calves.
  • A third Zeolite (NuFeed) deposit when fed at 6% of the ration yielded live weight gains of
    7% over the controls. When Zeolite was fed with urea, gains of 10% over the controls
    were recorded.

Garcia – Lopez et al (1988) feed lactating cows on pasture and concentrate with 2% Clinoptilolite (NuFeed). The fat production was significantly higher (P<05) than in the control group. The net acid base of the animals improved with the Zeolite (NuFeed) treatment, which appeared to buffer the electrolyte status of the cows.

Kondo et al (1969) cited by Mumpton and Fishman (1977) fed rations to young calves that included 5% by volume supplements of zeolite (clinoptilolite) (NuFeed). The zeolite (NuFeed) fed animals gained 20% more weight compared with control and consumed more feed.
However, the feed costs per kg of weight gain were significantly less than the control. The
incidence of diarrhea and soft-feces among the zeolite (NuFeed) feed calves was significantly reduced. (Refer table.)

Bartko et al (1993) report the use of Zeolite in the feed (at the preventative rate of 1g/kg of bodyweight twice daily) on five “calf-rearing farms” (4282 calves in total). There was a reduction in the incidence of diarrhea from 68.7% in the controls to 18.0% for the Zeolite treated calves. The mortality of calves was receded from 4.7% (98 calves) in the controls to 1.3% (29 calves) for the Zeolite treatment.
