Venezuela Develops Livestock Food
Alternative
CARACAS - Venezuelan scientists announced on
Friday they developed an alternative
proposal to increase food production of meat
and milk at low cost and improve
reproduction of pregnant cattle from 75 to
80 percent.
The project is entitled Strategic use of
local energy resources and its impact on the
intermediary metabolism that regulates
productive and reproductive responses in
dual purpose cattle in the tropic.
The research was funded by the National
Endowment for Science, Technology and
Innovation under the Ministry of Science,
Technology and Intermediate Industries.
The proposal was successfully applied to 200
meat-and-milk producer cattle, project
leader Anne Ryiz, of the Veterinary Science
School of the Central University of
Venezuela, explained in a press release.
The nutritional alternatives for cattle
reduce the supply of concentrated food based
on corn and sorghum and incorporate other
nutrients that reduce concentrates and lower
the cost of a pound of meat per animal.
They carried out experiments with different
food rations of local energy resources as
the bean plant, mulberry leaf, rain tree
seed, cottonseed, molasses and others in
animals with Holstein and some Brahman
genes.
Ruiz said there was an effect of feeding
level on cholesterol levels, stimulating
steroid hormones, one of those involved in
reproduction among other effects.
Currently, they are asessing the final
phase, in which body condition and
insulin-like growth factors are correlated.
Those factors have a bearing on the ovaries,
managing the ovarian and follicular
maturation so that the cow can breed
efficiently. |
