manufacture, roughage production, electricity utilization,
transportation and organic waste handling were included in the
system boundaries. Two scenarios, the system with biogas
production and the one in which manure was applied to plant
directly were compared. Global warming impact was offset in the
scenario that produced biogas. Although direct application of
manure as fertilizer could avoid the impact from chemical fertilizer
production, offset was not be able to achieve. Organic waste
treatment by an anaerobic digestion and recovery of energy in the
form of biogas were proved to be useful for global warming
mitigation from beef meat production in the country.

Abstract
A mail lamb was born in mixed sheep and goat (with 650 head) flock in
the suburb of Tabriz (Hervy) on January 11, 2007. The breed of this
lamb was Gezel and showed brachygnathia and Cleft palate. Lambing
was associated with dystocia. At physical examination, lamb was 2
days old. The dam had not anomalies in previous lambing (according to
client speech). Macroscopic examination presents the case had not
palate (hard and soft) and its length from nostril to commissure of the
lip measured 11 cm. In maxilla there was an opening with 1.5 cm in
width and 8 cm in length. The mandible bone had not any connection
with temporal bones joint in both sides. Analysis of urine and blood
samples did not present any significant variation expect a slight
lymphopenia (2580/µl). Feeding of this flock was on pasture and
occasionally some wheat silage, bread and bran. It is suspected that

1197 The Effect of Subclinical Experimental Infection with
Haemonchus Contortus on Carcass Quality of Karadi
Lambs

production,, Dohuk, Iraq
The current study was conducted to investigate the effect of sub
clinical infection with Haemonchus contortus on physical properties
of karadi lambs carcasses. Atotal of 14 karadi lambs 5-7 months old
were used in this study. The lambs were divided into two groups.
The first group (7 lambs) was considered as a control and remained
uninfected .The second group (7 lambs) were infected with 500
infective larvae (L3) of Haemonchus contortus Kg -1 body weight.
This study continued until 1 th weeks post-infection & at the end of
the study all lambs were slaughtered worm burden carcass quality
were estimated. Data were statistically analyzed by spss program
using T-test to determine the differences between control and
infected group. The result revealed that there was differences in
mean live weight at slaughter, empty live weight, hot carcass
weight, chilled carcass weight and dressing proportion were
(52.71),(48.64); (47.99),(43.78); (27.65),(24.62) ; (26.99),(24.03)
and (51.16%), (49.08%) between control and infected group
respectively but these differences statistically was not significant
However there was slight differences in rib-eye muscle area
(Longissimus dorsi) and fat thickness (mm) between control &
infected group (13.94),(13.41) and (7.15),(5.32) mm respectively but
these differences statistically not significant. No significant
difference were found in physical composition of carcasses in leg,
fore shank and three ribs (9,10,11) area between control & infected
multiple genes cause congenital anomaly in skeletal system and to
distinguish a single gene is very difficult especially when the clinical
case is very few for the study. Teratogenic factor such as toxic plant is
one of major etiologies in congenital anomalies that always should be
considered.

Coxiella burnetii causes Q fever in humans and animals (Coxiellosis)
worldwide. The prevalence of Coxiella burnetii antibodies in cattle has
been investigated. 322 blood samples were collected from cattle. The
serum was separated 24 h after sampling and stored at –20°C until
tested. The presence of IgG antibodies to Coxiella burnetii was
measured by indirect immunofluorescent antibody technique (IFA).
IFAT was performed according to the instructions of the manufacturer.
Serial twofold dilutions of positive sera were tested to determine end
titres. Cattle with 1:32 phase II antibodies were considered as positive.
40 out of 322 bovine serum samples (12,4%) were seropositive in the
IFA test.
Key words: cattle, IFA test, Q fever
groups. Generally the results indicate that there was slight effect of
subclinical infection with H. contortus on the productive
Performance of Karadi lambs. The study also revealed that there was
variation in resistance and resilience of lambs or there susceptibility
to parasitic infection.

Airborne dust and endotoxins in animal houses are significant
pollutants with a potential health risk for animals and humans
working in these facilities. Study assessing the level of airborne
contamination in dairy cows stable. The content of airborne dust and
endotoxin was determined. The study was conducted in a dairy
stable, dimensions 17.00x14.00x2.5 m. During the study, there were
25 Simmental lactating cows and 5 calves in the
stable. Measurements were done in the morning (before feeding and
milking) and in the evening, once a week, during two winter months.
Measurements were performed in the stable, in the area of animal
stay along the feedlot. Air temperature (°C), relative humidity (%)
and airflow rate (m/s) were determined by use of a TESTO device
(Testo Inc., Germany). Dust was sampled onto filters (Whatman
International Ltd., Maidstone, UK) by use of an SKC pump (SKC
