ABSTRACT
In search of new and better nutritional alternatives for the livestock exploitation of the region, with the use of
available raw material at your fingertips. The rationing of feed rations was applied to beef cattle fed with
supplementation of clone 51 (Paspalum dilatatum), forage shrubs ( Tithonia diversifolia ) and additives (mineral
salt, molasses). The research was exploratory, descriptive and field; the monitoring through the observation and
weighing of the increase of live weight per animal unit (U.A) in the bovine production system. For this
investigation, a population number of 20 animal units (U.A) was divided into two lots of 10 animals each for the
application of the evaluation; For the first case we have a feeding time of 6 hours per day in canoes and the rest we
obtain in the paddocks. Consequently, in the second batch they feed only on the pasture of the paddocks. To do this,
a statistical analysis of mean correlation and ANOVA was performed to observe the degree of association between
the studied variables, as follows: Initial weight, Mean weight and final weight, of each UA per lot (Supplemented
(S) and Not supplemented (NS). A Tukey test was also used to obtain the gain of live weight with significant
differences a (p> 0.05). In the experimental sample (S) a total weight gain of 454.5 kg was obtained at 61 days of
observation per batch; Compared to the control sample (NS) was a total of 216 kg. Likewise, the weight gain per
U.A is obtained in the two months of observation; For the S in the first month a weight gain of 0.73 g d-1 was
obtained. . Therefore, for month two a weight gain of 0.93 g d -1 was obtained. The weight-dependent table of the
second month (kg) explains that if there was weight difference (α = 0.0001 (Pr = F ) Between treatment one and
treatment 2. This means that in the second month (kg) for each of the lots it is related to the average weight (61
days), given by time, within which a Weight gain 24.8 kg.mes -1 based on supplemented and 10.6 kg.mes -1
corresponding to un supplemented.
