Abstract:
This research was conducted in order to investigate
the effects of supplemental fat and monensin on the level of Dry Matter
Intake (DMI), Average Daily Gain (ADG), final weight, Feed Conversion
Ratio (FCR), blood glucose level, Blood Urea Nitrogen (BUN), calcium,
phosphor, triglyceride, cholesterol and crude protein of the Zel lambs;
as well as commercial effects of monensin and supplemental fat on the
lambs fattening. Most of the time, ordinary food does not suffice the
animals needs. Thus, using high-energy materials like fats are important
in programming the diets. Moreover, adding some materials to the animal
diets could increase the animal efficiency and the products quality. Hormones,
antibiotics, ionophores are amongst the most important additives affecting
income in the lamb fattening industry. Monensin is the first ionophore
component proven to be effective in increasing efficiency of ruminant
animals. Twenty-four male Zel lambs were used with an age average of 3-4
months and an initial live weight of 21.94 ± 0.642 kg. A period
of eleven days was considered as the adaptation time and the experiment
was carried on during three 21-day phases (totally 63 days). The variables
for this study were supplemental fat on two levels of 0 and 4% and monensin
on tree levels of 0, 20 and 40 mg kg-1 on adrymatterbasis.
There were four repetitions for each treatment. The results of this research
reveal that different levels of fat and monensin do not have significant
effect on DMI, ADG, FCR and level of glucose. The food treatment had significant
effect on final weight, calcium level, BUN, phosphor, triglyceride, cholesterol
and CP (p<0.05). Also, they affect commercial productivity.
