ABSTRACT
A study of the efficacy of iron dextran to compensate the shortage
of iron in blood by injection in newly-born cattle calves suckling dams
milk. The experiment was carried out on a commercial flock belonged to
a private farm in Sharkia governorate during October-December 2003.
Animals used (60 calves) were divided into 2 equal groups (control and
treated one), the treated calves were allocated according to age into equal
six subgroups each of 5 calves [1, 7, 14, 21, 30 , 40 days age]. Each
treated subgroup received one injectable dose of 500 mg iron dextran
intramuscular per calf. Blood and serum samples were collected before
injection, then after 2 & 4 weeks post injection as well as after weaning
at 3 months old from each animal in all tested groups. Hematological and
biochemical investigations showed significant changes. No anaemic
cases were recorded during the first two months of age. However, iron
supplementation improved the hematological values (RBCs, Hb, PCV
and MCV) in injected calves more than their control. The significant
decrease of serum iron and increase of total iron binding capacity and
unsaturated iron binding capacity in control animals were improved in
animals treated with iron dextran till 21th day old. On contrary, the older
ages at 30 and 40 days were not corrected by one dose. After weaning (at
3 months old) no significant changes were recorded.
On conclusion, administration of 500 mg iron dextran to suckling
calves under 21 days old may be a helpful tool to prevent iron deficiency
anaemia in newly born calves.

INTRODUCTION
Whole cow milk as the sole diet is inadequate to fulfill in
supplying the requirement of the calf’s need for iron and the high growth
rate of neonatal animals (15). Iron nutritional interest was focused on
hemoglobin formation and oxygen transport -cytochrome enzymes and
animal immunity. Iron deficiency leads to microcytic hypochromic
anaemia which is manifested as retarded growth (10).
During first weeks of life, a transient mild to sever anaemia can develop
in the young naturally reared pre-ruminant calves, underdeveloped
ruminal digestive capacity acted synergestically to cause iron deficiency
(4). These animals showed pica, depraved appetite and consequently
weakness and morbidity were frequently (13 ,18). This varies with age,
species and with individual animal (10). Bunger et al. (4) recorded a
moderate iron deficiency anaemia in 32% of young calves at one week
old which increased to 73% at nine weeks, then decreased to 15% at 1226 weeks. At 28 days old, Mollerberg (17) revealed iron deficiency
anaemia in 13 -35 % of calves fed on milk. However, Saror (22) and Elgi
and Blum (9) found a decrease in serum iron concentration in calves
from birth to 4 weeks of old.
The aetiology of anaemia incidence indicated a general problem of the
rearing calves without iron supplementation (2) so iron treatment was
significant to prevent anaemia during the suckling period (3) .The
parenteral injection of iron dextran induced rapid recovery of animals
with iron deficiency anaemia (21).
Aim of study: The present study aims to provide more detailed
information about the changes in the values of hemoglobin (Hb), red
blood cells (RBCs), packed cell volume (PCV) and iron levels of the
newly born calves throughout the first days of suckling period. In
addition the evaluation of the efficacy of organic iron administration in
preventing anaemia during this period which is suitable time to handle
them.
MATERIAL AND METHODS
In this study, the experiment was carried out between October and
December 2003 on newly born apparently healthy cattle calves of native
breed and suckled dams milk naturally .
Groups: The tested animals were divided into 2 equal groups (control and
treated), each group subdivided according to age into six subgroups (1,7,
14, 21, 30, 40 days).
Feed: Composed of natural dam’s milk as the sole diet till 2 months age
(weaning time).
Treatment: Iron dextran (500 mg III hydroxide dextran complex*). It
was injected as 5 ml intramuscular single injection/calf in the thickest
portion of skeletal muscles on the posterior side of the hind leg.
Samples: Blood and serum were collected before injection and after 2 &
4 weeks of treatments and after weaning at 3 months age.
I-Hematological Studies: jugular whole blood samples were collected by
vacationer tubes containing potassium EDTA for hematological studies (8).
II-Biochemical Studies: jugular blood samples were collected by
vacationer plain tubes, for serum collection and determination of iron (7),
and Total Iron Binding Capacity (TIBC) (16). Unsaturated Iron Binding
Capacity (UIBC) was calculated according to the following equation:
UIBC = TIBC - serum iron µg/100 ml
Statistical analysis : Assessed by using student’s t - test (23)
RESULTS AND DISCUSSION
Nutritional diseases are considered as important cause of
economic losses of calves. Suboptimal performance due to inadequate
iron nutritional supply of calves from birth to weaning was recorded
(19).PCV of calves injected with iron dextran at birth remained within
the normal level as shown in table 1, indicating that erythrocyte
producing mechanism was functional and iron was needed to alleviate
pre-weaning anaemia in calves (5).
A marked reduction in RBCs, Hb and PCV, was recorded in samples
obtained from untreated calves at 2nd and 3rd weeks old compared with
treated calves. This finding was consistent with proposal of Rajkhowa et.al.
(20) concerning lack of available adequate iron dose. Keeping with this
line, the present study revealed that iron dextran administration rapidly
*
(Veterinary iron injection from Barneveld/Holland.)
improved PCV and MCV after 7 days post injection. Similar results were
obtained by Ceppi and Blum (6) and Elgi and Blum, (9) ,however, Hibbs
et. al. (14) detected no significant variation.
Insignificant elevation of hematological values (Table 2) at 30
and 40 days of age was recorded in treated groups compared with
untreated calves, so another dose of iron may be required to fulfill future
calf need.
Tables 1 and 2 revealed after weaning that most of the
hematological parameter showed non significant changes which may be
due to the ingested food supply. In contrary Bomba et. al.(1) recorded
20% of cases suffered from anaemia at weaning time. In the same
respect, Ceppi and Blum (6) revealed decreases in RBCs, Hb and PCV
in weaning calves.
In table 3 parameters of iron analysis revealed that iron dextran
injection at birth and at 7th day old maintained a high level of serum iron
during the first 2 months of age. Rajkhowa et al. (20) supported the afore
mentioned result. At 14th day old (Table 3), the control calves had
minimum level of serum iron, a result which agreement with Saror (22)
while in treated calves, a significant improvement of serum iron was
recorded. Table 3 shows significant reduction in the raised values of both
total iron binding capacity and the unsaturated iron binding capacity of
21 days old treated calves in comparison with untreated ones. The
obtained data were similar to that recorded by many others (6,9,12,24)
Furthermore, Ghergarui et. al.(11) recommended administration of two
doses of organic iron, each of 500 mg/3-6 weeks old calf with one week
interval to maintain iron serum level.
On the other hand, the present data regarding serum iron level
after weaning was high as those mentioned by Bomba et. al. (1).
In conclusion, treatment of newly born suckling cattle calves (up
to 21 days old) with a single dose of iron dextran (500 mg/head) resulted
in prevention of preweaning nutritional anaemia.
