Productive Response of Pelibuey Sheep to Supplementation in the Stretching Season in the Dry Tropic ()
ABSTRACT
Sheep meat production in the dry tropics of Mexico
is low in the dry season, due to lack of
forage, therefore, strategic supplementation is important to avoid
weight loss in animals; The research was carried out from August 15 to December 15, 2020 in order to evaluate the
productive response of pelibuey sheep in confinement, fed with pangola
grass hay (GH), plains grass silage (PGS) and supplemented with commercial feed
(CF) in the dry season. 16 sheep of the same weight and age were used, four
treatments were evaluated in them, in a completely random design; the
treatments were four levels of supplement 0, 0.1, 0.2 and 0.3 kg of AC fed with
HP and PGS. Sheep were dewormed at the beginning of the experiment and housed
in individual cages. The variables were: dry matter intake, daily weight gain
(DWG) and DM digestibility. DM consumption was different (P < 0.01),
the lowest consumption was 0.364 kg in treatment 1 (T1), with a maximum of
0.684 kg in T4; WDG was different (P < 0.01),
with a lower value of 0.044 kg·day-1 in T1 and a higher value of
0.112 kg in T4. The apparent digestibility of the dry matter showed a
difference (P < 0.01) which varied from 45.52 to 59.15% for T1 and T4, respectively.
DM intake, WL gain, and DM digestibility increased with increasing supplement
level at the levels studied.
