Research Institute during (2004) to study the effect of total or partial substitution of
soybean meal (SBM) by canola meal (CM) as protein supplementation in rations of
growing buffalo calves. Three isonitrogenous concentrate feed mixtures (CFMs) were
formulated by using 100% SBM, 50% SBM+ 50% CM and 100% CM as main protein
sources. These CFMs were fed to three similar groups of growing buffalo calves of an
average body weight of 116.38 a 0.28 kg and of 3-4 months of age, Calves were fed a
daily ration as 2.25% of the body weight CFM + 1% brseem hay (BH). Rice straw (R3)
was offered act (it). The experiment lasted for 140 days.
Digestibility trials using acrd insoluble ash (AlA) method were conducted at the
middle of the experimental period to evaluate the consumed rations, using three
calves for each group. Animals were biweekly weighed and the average daily gain
(ADO) was calculated.
The results showed that CM was lower in CF and higher in CF and EE than
SBM, being 38.2% vs 42.2%, 13 07 vs 3.4% and 8.24% vs 2.4%, respectively. The
ration which contained 50% SBM plus 50% CM as protein supplements (R2) showed
better OM, OM and CF digestibility coefficients than the other two rations containing
either 100% SBM (Rt) or 100% CM (R3). This ration also resulted in better ADG

rations (R1 and R2) which showed 0 980. 0.978 kg A06 and 5 912, 5,762 kg feed

significantly [P<0.05) showed better NHa-N and VFA's in the rumen fluid than the
other two rations. These results might be due to a complementary effect between
SBM and CM. Blood serum and rumen fluid parameters showed that feeding CM was

chicks subjected to feed restriction by feeding diets deficient in energy and protein
levels of 90% , 80% or 70% of starter recommended requirements during the second
week (8-14 days) of age as compared to those fed 100% of starter recommended
requirements. Then, birds were switched during 14-21 days of age to the control
starter diet. Seventy two day-old broiler chicks were allocated to 4 treatment groups of
18 chicks each in individual cages where every chick represents one replicate. All
treatment groups were fed the same grower and finisher diets from 22 to 37 days and
33 to 49 days of age. respectively.
The body weight gain was depressed significantly by feed restriction at the end
of the restriction period (14 days of age). However. at the age of 21 days, accelerated
growth eliminated any gap in body weight. There are significant differences in feed
conversion ratio among all treatments during the period of feed restriction. After 21
days of age, prior feed restriction had no negative effect on body weight gain neither
from 22-37 days nor from 38-49 days. Subjecting broiler chicks to early life mal
nutrition was more efficient in converting feed to gain compared to control diet. The
efficiency of energy utilization and protein utilization efficiency (PUE) improved when
the bird subjected to early energy-protien restriction and Subsequent refeeding.
Accordingly, the net profit improved compared to that of the control.
in conclusion, early feed restriction at levels of 90% . 80% or 70% of starter

Results obtained can be abstracted as follow:
1-Body weight, relative weight values of carcass, liver, gizzard. kidney and heart did

study.
2-Abdominal fat percentage was destined gradually and significantly (P<0.05) as feed
restriction levei increased.
3-Commercial carcass cuts {breast and thigh muscles) yielded a higher (P >005)
percentage distribution for breast portion and less (P>0.05) percentage distribution
for thighs than the control group.
4-Dry matter and ash content were nearly similar in all groups, while protein content
insignificantly increased with increasing energy-protein restriction levels. However,
ether extract of control group recorded the highest value compared to the others.
5-Serum total protein, albumin, globulin and uric acid content exhibited insignificant
values in treatment groups.
B-Total cholesterol, triglycerides, HDL and LDL levels in restricted feed broilers were
concomitant with those of body fat content and abdominal fat.
7-Semm glucose, T3 and T4 levels were insignificantly fluctuating in broilers fed

It could be suggested that the effect of feed restriction in broilers at an early
age is more evident in lipid metabolism rather than protein metabolism, to obtain a
better understanding of their nutritionai and physiological responses.https://jappmu.journals.ekb.eg/article_237999_7bcfb30baea84acb085f9c3f1c120d2b.pdfMansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-364230620050601EFFECT OF FENUGREEK SEEDS (Trigonella foenum- graecum L.)

compositions of lactating goats was targeted in this study. Twenty seven lactating

respectively) of nine animals each. Two groups randomly received either 10 or 30

for 7'0 days. Feed intake of ration ingredients and total dry matter intake (1685 4,
1600.4 and 1610.3 glhld for 1st, 2nd, and 3rd groups, respectively) did not differ
among the three groups. Milk production increased as a result of supplementing
rations With fenugreek Seeds. The lower level of seeds (10 glhld) showed the highest
level of milk production (684 mllhld) followed by the 30 gi'hld seeds level (5262
ml/hi‘d). EifiCiency of feed conversion into milk (Kg feed DlW Kg milk) was the highest
for the 10 glhid seeds leves. it appears that lenugreek seeds increased milk
production by improving feed efficiency. Milk composition was rtot affected by the
addition of lenugreek seeds.
It is concluded that fenugreek seeds as a potential feed additive may exert a
positive effect on milk production, yet further studies are warranted.https://jappmu.journals.ekb.eg/article_238001_9de5e673f0e7ee7a336e8ee04cf57f83.pdfMansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-364230620050601NUTRITIONAL EVALUATION OF RATIONS AND BLOOD PARAMETERS AS AFFECTED BY FENUGREEK SEEDS (Trigonefla foenum graecum L.)
