Abstract
Selenium supplementation on goat kids performance and their incorporation into their tissues were studied in a feeding experiment. The experiment lasted 98 days on 15 goat kids and comprised 3 treatments (trials) each on 5 animals: group I, Kids were fed unsupplemented, basal diet served as control, group II, was fed the basal diet supplemented with 2mg/sodium selenitel/head/day, and group III was supplemented with 0.7 mg selenium/head /day added to basal diet.
Results obtained can be summarized as follows:
There was a positive growth response to Se supplementation compared with sodium selenite. No significant differences were observed with the total dry matter intake among the three groups. Selenium supplemented group had the highest values of digestibility coefficients of all nutrients. The nutritive values as TDN and DCP were highest with the Se supplemented group followed by the control group, while the sodium selenite group (SS) recorded the lowest values. Also, Se group (S) had the higher positive nitrogen balance followed by the control and the sodium selenite group. Kids received SS or supplemented rations retained Se in their body more than in the control group.
It was noticed that kids that received Se and control ration had higher protein and lower fat percentage in their carcass cuts than the SS group.
