Page No: 1-6
The study compared the profitability of catfish, tilapia
and carp production in South-East Nigeria. Three states, Anambra, Enugu and Ebonyi
were randomly selected from the five states that make up the south-east geo-political
zone. All the registered fish farmers in three states were selected for the study.
This gave a sample size of 192 respondents. Data for the study were collected from
both primary and secondary sources. Data collected were analyzed using both descriptive
and inferential statistics. Budgetary technique was used to determine gross margin.
Profitability ratios were calculated to determine economic performances of catfish,
tilapia and carp production. Results show that fish farming is dominated by males
(73.0%) with an average age of 47 years. Majority of the farmers (44.80%) have a
bachelor’s degree /HND. The gross margin analysis and profitability ratios revealed
that catfish farming is the most profitable in the area with a net income (profit)
of N326,450, and a BCR of 1.26. High cost of farm input and poor access to credit
facilities have greatly discouraged many people from venturing into fish farming
it was recommended that more fish hatcheries and feed mills be constructed to reduce
the problems fish farmers face in the zone.

This study was conducted to evaluate the benefit-risk
potentials of turmeric at different levels on performance, intestinal histomorphology
and microbiota of Nile Tilapia (Oreochromis niloticus). Two hundred forty juvenile
tilapia were allocated as following: T1 (control) received basal diet only, the
other treatments (T2, T3 and T4) received basal diet with turmeric at a rate of
2, 4 and 8 g/kg diet, respectively. There was a significant increase in T2 and significant
decreases in both T3 and T4 as compared to control in final weight, weight gain,
specific growth rate and feed efficiency ratio. In addition to significant improvement
of feed intake/weight gain in T2 and depression in T3 and T4 there were non-significant
changes between the treatments in final condition factor. Intestinal folds lengths
showed significant increase in T2. Histomorphology of the proximal portion of small
intestine showed decrease in enterocyte height in T3 and T4. The T4 group showed
hydropic degeneration in the villi with the goblet cells loss with mucus lakes.
Results of microbiota revealed a significant increase in both T3, T4 and a non-significant
increase in T2 in total bacterial count and total lactobacillus count in comparison
with control group. Fecal coliform count showed non-significant decrease in T2 and
T3. In conclusion, turmeric 2 g/kg supplementation showed beneficial effects on
performance and gut health,4 g/Kg showed a negative effect on the performance with
non-obvious effect on gut health, and 8 g/Kg showed adverse effects on intestinal
histomorphology including increased fecal coliform count and depressed growth performance.

Huthail Najib and Abdulaziz Al-Aqil
Page No: 26-30
This study was carried out to evaluate the physiological
responses, in terms of enzymes activity, of local Saudi and exotic layers to seasonal
variation in ambient temperatures. Three breeds of layers represented by Saudi Local
(SL), Naked Neck (NN) and White Leghorn (WL) were used in this study. Estimation
of alkaline phosphatase, creatine kinase, lactic acid dehydrogenase and aspartate
amino transferase enzymes was performed according to the procedure listed by AOAC
(2000). Result of the study indicated asignificant breed * period interaction was
found only in creatine kinase. However, alkaline phosphatase, lactic dehydrogenase
and aspartate amino transferase were affected by breed of the birds. Likewise, seasonal
variations in temperature (effect of period) had a significant effect on lactic
dehydrogenase and aspartate amino transferase enzymes. It was concluded based on
this study and the biological responses of the birds to the seasonal variation in
the temperature that naked neck birds can perform efficiently in areas where hot
climate prevailed such as in Saudi Arabia.

Page No: 31-43
The present research work was conducted with the aim
of characterization of four cultured tilapia species populations namely Oreochromis
niloticus, Oreochromis aureus, Oreochromis galilaeus, and Tilapia zilli using Random
Amplified Polymorphic DNA (RAPD) markers. To achieve such a purpose, a total number
of 40 apparently healthy fishes (10 from each of the four species) were obtained
from Fish Research Centre, Suez Canal University (Ismailia, Egypt) .Bulked samples
from each population were examined by RAPD-PCR technique using nine random10- mer
primers (OPA-12, OPA-13, OPA-14 OPA-15, OPA-17, OPA-18, OPA-19, OPA-20, OPO- 11).
The results of this experiment revealed that the 9 primers produced a total of 177
easily scorable RAPD bands ranged in molecular size from approximately 149 to 2787
bp. Dendrogram indicates that he genetic similarity between O. niloticus and T.zilli
was higher compared with that between O.niloticus and both S.galilaeus and O.aureus.
Also, between S.galilaeus and O.aureus the similarity was low compared with that
of T.zilli. In conclusion, population characterization of tilapia speciesin this
study had provided a baseline for future genetic improvement and monitoring ofthe
gene pools of cultured tilapia stocks.

Page No: 55-71
The present study was conducted to investigate the effect
of Yucca shidigera and/or exogenous enzyme on nitrogenous compound in Nile tilapiafishes
as well as apparent Digestibility Coefficient (%ADC) for crude protein. Apparently
healthy, 800 mixed-sex Nile tilapia with same average body weights were randomly
allocated into 4 groups with 2 replicates each as follow: the first group (G1) served
as a non-treated control; the second group (G2) received basal diet supplemented
with Yucca Shidigera Extract (YSE) 150 mg/kg; the third group (G3) received basal
diet supplemented with 0.5 g/kg Exogenous Enzyme (EE); the fourth group (G4) received
basal diet supplemented with a combination of YSE 150 mg/kg and 0.5 g/kg EE. Experimental
fishes were put in 1 cubic meter tanks with same amount of water and experiment
was terminated when ammonia level was stressful for control group. Result revealed
that using of YSE reduce ammonia rapidly as soon as 24 hours with significant reduction
in NH3 and NH4 + at 36 hours then become non-significant, at the same time YSE significantly
decrease %ADC. Combined yucca with enzyme showed significant decrease in NH3 and
NH4 + with increase in NO2 and NO3, also represented non-significant increase in
%ADC. From this results it was concluded that using combination of yucca and enzyme
revealed better effect on ammonia level in water and results recommended to monitor
nitrite level.

Page No: 72-77
Toxocariosis due to Toxocara vitullorum is a major parasitic
problem among suckling and freshly weaned cattle and buffalo calves. The parasite
is more pathogenic for buffaloes compared to cattle. Prenatal (in-utero) and postnatal
(transcolostral) transmission of the larvae to the foetus or the suckling calves
results in heavy worm burden that may be often fatal. A case of clinical toxocariosis
was observed among one month old buffalo calves of Pandharpuri breed. Quantitative
faecal examination revealed count of 2700 to 27,600 Toxocara eggs per gram of faeces.
Calves were treated with doramectin and fenbendazole and the results were compared
by recording faecal egg output (EPG) up to 21 days post treatment.

Adel S El Nabtiti
Page No: 91-102
One of the most important challenges facing turkey production
is high stocking density, therefore this study was conducted to evaluate the effects
of different stocking density of 2 different turkey breeds (The Egyptian Black Baladi
and The Commercial White Nicholas) on productive performance (live body weight,
weight gain, feed consumption and feed conversion ratio) and some stress indicators.
A total of 108 poults-8 weeks old were allocated into 3 different rearing systems:
G1; control (4 birds/m2); G2 and G3; reared at 6 and 8 birds/m2, respectively. A
negative significant (P<0.01) impacts were reported of both 6 and 8 birds/m2 groups
on productive performance parameters in both breeds; additionally, theses parameters
showed direct relationship with the age. Higher stocking density (8 birds/m2) had
been altered the differential leucocyte counts which associated with a significant
(P<0.01) increase in corticosterone and decrease in both thyroid hormones (T3 and
T4) as compared to control. There was a significant (P<0.01) high H/L ratio with
Black Baladi as compared to White Nicholas. White Nicholas breed reared in 8 birds/m2
as compared to the other 2 White Nicholas groups showed a significant (P<0.01) increase
in H/L ratio with corticosterone hormone level. On the other hand, Black Baladi
breed showed a significant increase in corticosterone hormone level at 8 birds/m2
followed by 6 birds/m2. White breed at 8 birds/m2 showed a significant decrease
in both T3 and T4 as compared to their control, on the other hand, Black Baladi
reared in 8 birds/m2 showed a significant decrease in T4.

Alshimaa A Hassanien and Nahed Mahmoud Abdel-Aziz
Page No: 107-113
This work was performed to detect the existence of Staphylococcus
aureus (S.aureus) and some of their enterotoxin genes as Sea, Seb and Sec among
food handlers and fast food samples like ready to eat meat prepared by them in different
fast food premises in Sohag city, Upper Egypt using bacteriological isolation of
S.aureus and multiplex PCR for enterotoxin genes detection. The results illustrated
that 14 (8%) out of 175 fast food samples and 23 (26.7%) out of 86 food handlers
harbored S.aureus pathogen. Age, gender and education status of food handlers not
correlated with S.aureus infection while their hygienic practice during food processing
is significantly correlated with infection. S.aureus enterotoxin genes was detected
in 19 (51.3%) out of 37 isolates and Seb is more prevalent. This study highlights
on the role of food handlers in dissemination of S.aureus food poisoning to consumers
through food especially heat treated meat.

EFFECT OF HEAT STRESS ON DIFFERENT REPRODUCTIVE PROCESS
IN ANIMALS AND ITS AMELIORATIVE MEASURES THROUGH NUTRITIONAL MANAGEMENT
Balamurugan B, N S Kharayat and Om Shankar
Page No: 114-126
In most mammalian species including cattle and buffalo
heat stress has deleterious effects on nutritional, physiological and reproductive
functions. Exposure of animals to a hot environment causes an increase in body temperature
in mammals, including domestic animals. High ambient temperature also causes a decrease
in the length and intensity of estrus by disturbing ovarian function as well as
decreasing pregnancy rate after artificial insemination. Therefore, it is important
to understand the effects of heat stress on reproductive function in order to improve
the production of domestic animals. Heat stress decreases appetite, weight gain,
and milk yield in dairy cattle. It also adversely affects the reproductive performance
of both sexes. In female animas it adversely impacts oogenesis, oocyte maturation,
fertilization development and implantation rate. There are several nutritional strategies
to consider during heat stress. A common strategy is to increase the energy and
nutrient densities (reduced fiber, increased concentrates, and supplemental fat)
of the diet, as feed intake is markedly decreased during heat stress. The concentration
of all nutrients will need to be increased in diets as dry matter intake decreases
during heat stress.

Page No: 127-138
This study was conducted to investigate the occurrence
of E. coli in raw milk of sheep and goat in Luxor Governorate, Egypt. A total of
150 samples of raw milk of sheep and goat (75 each) were collected. The results
showed that 9.3% of each raw sheep and goat’s milk samples were contaminated with
E. coli, while, E. coli O157 could not be detected. Out of 7 E. coli strains isolated
from raw sheep’s milk samples, 5 strains were serotyped as O28, O166, O 27, O 128,
O 26 and 2 did not give any agglutination with the used ‘O’ E. coli antiserum (ONT).
On the other hand, E. coli isolates of raw goat’s milk were serotyped as O27, O125,
O78, O152, ONT (one each) and 2 strains serotyped as O115. E. coli isolates were
molecularly characterized for the presence of some virulence genes (stx1, stx2 and
eaeA genes). PCR products analysis revealed that only one strain isolated from raw
sheep milk samples (E. coli O26) was positive for presence of stx2 only, while E.
coli strains obtained from goat milk lacked both stx1 and stx2. Also, eaeA gene
was located in 85.7 and 100% of the isolated E. coli strains obtained from raw sheep
and goat milk, respectively. Enterohemorrhagic E. coli (EHEC) and Enteropathogenic
E. coli (EPEC) were detected in 7.14 and 85.7% of the total E. coli isolates, respectively.
