Abstract
Sloan, D.R., Harms, R.H., Abdullah, A.G. and Kuchinski,
K.K. 2000. Variation in egg content density makes egg specific gravity a
poor indicator of shell weight. J. Appl. Anim. Res., 18: 121-128.
A study was conducted to measure the variability in egg
content specific gravity (ECSG) among breeds and strains, and ages of
laying hens. Also information is presented concerning how the specific
gravity of egg content (EC) affects the specific gravity of egg (ESG). The
observed ECSG ranged from a low of 1.0298 to a high of 1.0352. Based on
the formula of Harms et al. (1990) a change of ECSG from 1.029 to 1.035
would change the ESG from 1.0823 to 1.0883 and the eggshell weight from
5.64 to 6.18 g. ECSG on a commercial farm ranged from 1.0323 to 1.0352.
This resulted in calculated ESG from 1.0856 to 1.0885 and calculated SW
from 5.84 to 6.21g. Researchers and industrymen must be very careful in
using ESG data in making decisions relating to eggshell quality.

cholecystokinin in the regulation of food intake in the neonatal chick. J.
Appl. Anim. Res., 18: 129-136.
The effects of intracerebroventricular (ICV) injection of
chicken gastrin and cholecystokinin (CCK) on food intake were compared in
the neonatal chick. In Experiment 1, the effect of 131 pmol of chicken
gastrin (36 amino acid residues) on food intake was compared with 66 and 131
pmol of CCK-8S over 2h. Chicken gastrin strongly inhibited food intake, but
both levels of CCK-8S did not. The similar effect of 131 pmol chicken
gastrin was obtained by 262 pmol CCK-8S at 1h after ICV injection in
Experiment 2. This suppressive effect of chicken gastrin continued over 2h
after ICV injection, though the effect of CCK-8S had disappeared by 2h. In
Experiment 3, the effects of 131 pmol of CCK-8S, CCK-33S and chicken gastrin
were compared. The effect of CCK-8S was weak, but CCK-33S and chicken
gastrin similarly and strongly inhibited food intake of chicks. These
results suggested that the suppressive effect of food intake of gastrin/CCK
family may be dependent upon the length of amino acid sequence.

performance and reproductive development. J. Appl. Anim. Res., 18 : 137-147.
The effects of laidlomycin propionate (LP) on beef bull
growth performance and sexual development were determined in an 84 day
study. Forty embryo transfer Angus bulls were fed three complete diets
containing LP levels of either 0, 10 or 20 g/t. Bulls were fed daily using
electronic feeders to obtain individual feed intake. Full weight and scrotal
circumference (SC) were evaluated at 28 day intervals. Breeding soundness
examinations were conducted to characterize semen. Muscle mass and body fat
were estimated using real-time ultrasonography. Laidlomycin propionate did
not influence daily gain, dry matter intake, feed efficiency, subcutaneous
or intramuscular fat deposition, but Longissimmus muscle deposition
was enhanced. Among treatments, bulls had similar (P>0.05) SC measurements
and no detrimental effects on semen quality or sperm morphology were
observed. Supplementing growing bulls with laidlomycin propionate for
improved performance did not detrimentally affect sexual development.

Two cases of Rhodococcus equi infection in Spanish
goats have been described. Clinical signs were chronic weight loss,
agalactia, fever, prone position and apparent abdominal pain in one of them.
Multifocal well encapsulated scattered abscess were observed in liver.
Stress, sanitary deficiencies and moderate cold environment few months ago
could have caused the establishment of infection. |

histology of the sinu-atrial node of goats (Capra hircus). J. Appl.
Anim. Res., 18 : 153-158.
Anatomy of the sinu-atrial node was studied in 5 female
goats. The sinu-atrial node(12.75mm × 1.5mm × 1.7mm) lied 0.18mm-0.25mm
beneath the epicardium, at terminal sulcus, near the junction between the
cranial vena cava, lateral wall of the right atrium and the right auricle.
Its shape was elongated and relatively cone shaped. Its cranial end was near
the myocardium of atrial wall. Histologically, it normally contained a dense
collagen frame and the cells with clear perinuclear zone (P) and
transitional cells (T) were the principal cells of parenchyma. The "P" cells
were bigger than "T" cells and smaller than the ordinary myocardial cells.
At the junction between "T" cells and "P" cells intercalated discs were not
seen. Near the central section and toward the cranial margin there is a
distinct arteriole that supplies the node.

growing-finishing pigs. J. Appl. Anim. Res., 18: 159-164.
The field pea (Pisum sativum) cultivar Glenroy
(187 g/kg CP) was evaluated as an alternative protein source in diets of
grower-finisher pigs. Four diets were formulated on iso-nutrient basis
(»14.4 MJ/kg DE, 160 g/kg CP, 9.3 g/kg lysine, 5.3 g/kg methionine and
cystine, 2.1 g/kg tryptophan) so that soybean oilcake meal and maize meal
were substituted by increasing levels of fieldpeas (16%, 32%, 48% and 64%).
Forty castrated pigs (78 d, 21.7±2.6 kg) were individually housed and 10
pigs were fed on each diet ad libitum for 84 days. DM intake, average
daily gain and feed conversion efficiency, all depressed on the highest peas
level in the diet. The DE content and N-retention of the 64% peas diet were
significantly (P<0.05) lower than those of the 16% and 32% pea diets. Though
dressing percentage was not affected by dietary treatment, P2
back fat thickness was significantly decreased in the 64% peas inclusion
group resulting in leaner carcasses. This was mainly due to lower slaughter
weights. It was concluded that up to 32% of the field pea cultivar Glenroy
in the diets of growing pigs can be recommended.

Appl. Anim. Res., 18: 165-169.
The monthly records of various livestock species (cattle,
sheep, goat, pig, horse, donkey and dog) slaughtered for meat in Enugu state
for a period of 8 years (1988-1995) were used to determine the contribution
of small ruminants to meat supply in the State. The contribution made by the
small ruminants was lowest (16.13%) in 1991 and highest (24.62%) in 1993
with an average contribution of 20.40±4.02% during the 8 years period of
survey. Most small ruminants were slaughtered in the Enugu zone of the
state. This study confirms the usefulness of sheep and goats in animal
protein supply in the state. |

Isoflupredone acetate (Predef. 2X) on ovulation and oestrous cycle in mare.
J. Appl. Anim. Res., 18: 171-175.
To evaluate the effect of Isoflupredone acetate (Predef.
2x) on ovulation and the length of the oestrus cycle in the mare, six
non-pregnant reproductively sound mix-breed mares were used in this study.
The first oestrus cycles of the mares were monitored and considered as
control oestrus cycles. Oestrus cycles of the mares were synchronized using
a dose of prostaglandin F2a (Lutalyse, 10 mg/mare) and hCG (3000 I.U./mare).
Each mare was injected intramuscularly 20 mg of Isoflupredone acetate from
day 10 of the oestrous cycle up to the day of ovulation. Ovulation occured
in all mares 24 to 48h after hCG treatment. There was no significant
difference in the length of the oestrus cycle, the duration of the
follicular and luteal phases between the control and Isoflupredone acetate
treated oestrus cycles. It is concluded that there was no detrimental effect
of Isoflupredone acetate on the length of oestrus cycle and ovulation in the
mare.

phase lactation characteristics of red sokoto goats. J. Appl. Anim. Res.,
18: 177-184.
The ascending phase milk yield characteristics were
evaluated in Red Sokoto goats using 120 days milk yield records obtained
from a total of 92 lactating does in 6 herds, collected over a two year
period. The ascending phase characteristics were highly variable
(47.6-74.5%) and were significantly (P<0.01-0.05) influenced by herd, season
and parity, but not by litter size and litter composition (P>0.05). Highly
positive and significant (P<0.01) correlations (r=0.62) exist between total
yield and ascending phase total and average day yield, respectively.
Negative and significant (P<0.05) correlation (r=-0.30) was observed for
peak week and days in the ascending phase. The significant herd and seasonal
effects may have practical implications in determining optimal feeding
management and season of breeding to maximize total lactation yield. The
effect of parity point to the fact that it is not necessary to cull
lactating does before parity 5.

To evaluate the effect of feeding Salicornia bigelovii,
a halophylte, eleven Najdi camels (202 kg) were divided into two groups and
fed on diets containing either 25% Rhodes grass or Salicornia hay for 120
days. Carcass characteristics were generally not affected by Salicornia hay.
Similarly proximate composition, minerals, essential amino acids and fatty
acids of M. longissimus were generally not affected by dietary treatments.
However, Na, linoleic acid, Polyunsaturated fatty acids and methionine were
higher in Salicornia hay fed camels, whereas, essential amino acid valine,
histidine and phenyl alanine were lower in these camels. It is concluded
that Salicornia hay can be included at 25% level in the diet of adult Najdi
camels.

Abstract
Aredo, T.A. 2000. Effect of roughage type and duration of
nutrient restriction on compensatory growth of crossbred bulls. J. Appl.
Anim. Res., 18: 193-198.
The effect of nutrient restriction imposed by feeding
poor quality roughage (hay for 6 months and maize stover for 6 or 3 months)
and subsequent replenishment through concentrate feeding (3 kg/h/d for 120
days) on compensatory growth was studied using 18 crossbred (5/8 Friesian,
3/8 Zebu) bulls ranging in age from 1 to 2.5 years. During the restriction
period, animals on hay gained 1.3 kg live weight per head, whereas those on
maize stover for 6 months lost 22.8 kg per head. The difference in weight
gains of animals restrictedly fed on maize stover for 3 and 6 months was not
significant (P>0.05). At the end of the experimental period, body weight
gain of the animals was not affected (P>0.05) both by the feed types and the
duration of nutrients restriction. Feed cost per kg of weight gained was
significantly (P<0.05) lower for animals fed on maize stover for 6 months
compared to those fed on hay for the same duration. It is concluded that in
areas where maize stover is available and livestock feed is scarce,
especially during the dry season, animals may be fed on maize stover for 6
months followed by a realimentation period of about 4 months.

Comparative assays on the concentration and types of
sialoglycoproteins (glycophorins; GP) on the erythrocyte membrane of three
different cattle breeds and buffalo were carried out. Twenty-eight cattle
consisting of ten N'Dama (Bos taurus), fourteen White Fulani, (West
African Zebu; WAZ), four Boran (East African Zebu; EAZ) and two buffaloes
were used. The erythrocytes of WAZ and EAZ cattle contained significantly
lower (P<0.05) concentrations of sialoglycoproteins (9.85±0.61 and 9.46±1.35
mg/109 erythrocytes, respectively) than those of N'Dama cattle (Ibadan-based,
12.54±0.37; Nairobi-based, 12.28±0.85 mg/109 erythrocytes) and
buffalo (10.43±1.25 mg/109 erythrocytes). Electrophoretic
separation of the erythrocyte GPs revealed that both N'Dama cattle, its 75%
crosses and buffalo expressed three bands corresponding to human erythrocyte
GPA, GPC and GPB, with 39, 30 and 25 kDa apparent molecular masses,
respectively. On the other hand, WAZ cattle expressed GPA and GPC while EAZ
cattle erythrocytes expressed only the GPA band. These findings indicate
that the N'Dama cattle and buffalo, both of which are known to be
trypanotolerant, have qualitatively and quantitatively higher levels and
types of erythrocyte membrane glycophorins than the trypanosusceptible WAZ
and EAZ cattle. It is concluded that these erythrocyte membrane attributes
of N'Dama and buffalo may be heritable characteristics and possible markers
for trypanotolerance.

observations on bufallo parotid gland. J. Appl. Anim. Res., 18: 215-220.
The fine structure of the parotid gland of buffalo was
studied by electron microscopy. The parenchyma of the gland consisted of
compound tubulo-alveolo-acinar serous secretory units, intercalated ducts,
nonstriated intralobular ducts and excretory ducts. The secretory units were
mostly tortuous and lined with cells of variable heights, giving a scalloped
appearance to secretory lumina. Secretory cells contained rough endoplasmic
reticulum, Golgi apparatus and numerous mitochondria with dark granules. A
few electron-dense secretory granules of different sizes were also found in
the apical cytoplasm of secretory cells. Unlike other ruminants, the luminal
surface of the secretory units and intercellular canaliculi were devoid of
any microvilli. Secretory granules were not found in the cytoplasm of
intercalated and nonstriated intralobular duct cells.

A study was conducted on hundred-one heifers aging 1.5 to
2.5 years to determine the effect of infection with different
gastro-intestinal parasites namely, fasciola, paramphistomum, schistosome,
strongyle and coccidia on the immune response to tuberculin test. De-wormed
heifers reacted to tuberculin injection significantly differently (P<0.05)
than non de-wormed ones. Significantly (P<0.05) higher immune response to
tuberculin injection was observed when animal was negative than when it was
positive for fasciola or strongyle only. This preliminary work warrants
further investigation on the importance of de-worming animals before
conducting tuberculin test for the diagnosis of bovine tuberculosis.
