##### Abstract

The present research was conducted to evaluate inclusion of
sesame seed by-products in diets for finishing rams and goats.
A total of 16 non-castrated rams were used in the study. They were
divided into four groups of 4 animals each. Each animal was put in a pen
and individually fed. Their average initial liveweights were 25.25, 25.25,
25.13 and 25.25 kg per head, respectively. Their ages ranged between
6 – 7 months.
Animals were kept for a period of nine weeks plus two weeks
adaptation period and fed on the experimental diets.
Four rations were formulated from sesame seed hull, sesame seed
husk, and wheat bran. Ration A consisted of 50% sesame seed hull and
50% sesame seed husk (a byproduct of processing sesame seed- from
tahnea sweet factories). Ration B, consisted of 45% sesame seed hull,
45% sesame seed husk and 10% wheat bran. Ration C consisted of 40%
sesame seed hull, 40% sesame seed husk and 20% wheat bran. Ration D
consisted of 35% sesame seed hull, 35% sesame seed husk and 30%
wheat bran.
Salt lick blocks were available all the time. In addition, green
fodder was given at a rate of one kg/head weekly as vitamin A source.
Average daily liveweight gain for rams fed ration A, B, C, and D
was 44.92, 83.33, 90.00 and 58.25 grams, respectively.
Average dry matter intake for ration A, B, C and D were 664.70,
1178.80, 1056.70 and 1068.70 grams, respectively.A total of 16 non-castrated Nubian kids were involved in the study.
They were divided into four groups of 4 animals each. Each animal was
put in a pen and fed individually. Their average initial liveweight was
10.88, 10.75, 10.88 and 10.75 kg/head, respectively. Ages ranged
between 3 – 4 months. Kid groups were randomly divided among the
experimental diet A, B, C and D.
Animal were kept for a period of nine weeks plus two weeks
adaptation period. They were fed on ad-libitum basis and on the same
rations that were fed to rams earlier.
Salt lick blocks were available all the times. In addition, green
fodder was given at a rate of one kg/head weekly as vitamin A source.
Average daily liveweight gain for ration A, B, C, and D were
−7.94, 4.92, 6.03 and 10.95 grams, respectively.
Average daily dry matter intake per kid from the ration A, B, C
and D were 158.33, 208.00, 274.67 and 338.50 grams, respectively.
A digestibility trial was carried out in rams using total collection
method. Two animals from each treatment were randomly selected and
given the same ration that have been fed to them. Feed intake and faeces
output were recorded daily for 8 days on an individual basis.
The apparent digestibility values for ration A were 39.29, 48.01,
73.75, 45.35, 29.56 and 74.45 for dry matter (DM), organic matter (OM),
neutral detergent fibre (NDF), crude protein (CP), crude fibre (CF) and
ether extract (EE), respectively. As for ration B digestibility values were
43.75, 51.01, 73.54, 58.23, 50.09 and 64.04 for DM, OM, NDF, CP, CF,
EE respectively; for ration C digestibility values were 48.10, 55.83,
18
76.51, 58.80, 56.48, and 77.72 for DM, OM, NDF, CP, CF and EE,
respectively; for ration D digestibility values were 48.82, 56.99, 78.26,
59.84, 49.34 and 85.51 for DM, OM, NDF, CP, CF and EE, respectively.
The dry matter degradability for ration A, B, C and D was
determined using nylon bag technique in a fistulated steer. The periods of
incubation were 0, 4, 8, 16, 24, 48 and 72 hours. Samples of zero hour
represented water soluble fraction.
Dry matter degradability for the easily degradable fraction (a) and
the slowly degradable fraction (b) were 14.65 and 65.08 for ration A;
20.57 and 62.84 for ration B; 27.49 and 58.90 for ration C; 24.84 and
57.30 for ration D.
Degradation rate (c) of slowly degradable fraction (b) was 0.10,
0.08, 0.07 and 0.10 for the ration A, B, C and D, respectively.
Effective degradability (ED) at rumen outflow rate of 2%, 5% and
8% were 68.33, 57.53 and 50.63 for ration A; 70.47, 58.77 and 51.63 for
ration B; 72.70, 61.07 and 54.20 for ration C; 72.77, 63.37 and 57.03 for
ration D.
Lag time (LT) were 2.13, 0.93, 0.00 and 0.23 for ration A, B, C
and D, respectively.
Potential degradability (PD) were 79.33, 83.43, 86.40 and 82.13
for ration A, B, C and D, respectively.
Carcasses of rams and kids were evaluated for meat quantity and
quality.
Average dressing percentage was 39.45, 39.23, 44.35 and 43.94 for
the rams fed on ration A, B, C and D, respectively.

Regarding meat quality attributes water holding capacity (WHC)
values were 1.31, 1.45, 1.14 and 1.22 for ration A, B, C and D,
respectively. In sensory evaluation meat colour of rams lightness, redness
and yellowness was 38.90, 13.55 and 7.80 for ration A; 37.25, 12.60 and
7.15 for ration B; 35.30, 12.10 and 3.65 for ration C; 37.60, 13.45 and
5.10 for ration D.
Average dressing percentage was 45.90, 45.52, 42.14 and 45.74 for
kids fed ration A, B, C and D, respectively.
For meat quality attributes water holding capacity (WHC) values
were 1.29, 1.68, 1.35 and 1.75 for ration A, B, C and D, respectively. In
sensory evaluation meat colour of kids lightness, redness and yellowness
was 35.30, 12.45 and 5.70 for ration A; 35.40, 13.80 and 6.95 for ration
B; 33.35, 12.80 and 5.10 for ration C; 32.40, 11.75 and 5.85 for ration D.
