Abstract

In the minor species program of the “Guaslán” Farm in Riobamba city, were used three different levels of garlic extract (4, 6 and 8%) in guinea pigs drinking water in the growing-fattening stage to compare with a control treatment. They were used eighty guinea pigs (40 females and 40 males) of the improved line of 15 days of age. It was applied a completely randomized design (CRD), with a combinatorial arrangement of 2 factors, 5 repetitions and the experimental unit size (EUS) was 2 guinea pigs. The experimental results about the productive aspect for the final weight did not record significant differences. For weight gain, feed conversion, carcass weight and carcass yield, the best results favored guinea pigs treated with 8% of garlic extract with 706.65 g, 5.70, 835.25 g and 74.76% in their order. Concerning the sex factor, for the variables: final weight, weight gain, carcass weight, and yield to the carcass were significant differences being more efficient the males compared to the females, however in the feed conversion did not register significant differences. As for the interaction, for the variables weight gain and yield were reported the best results in guinea pigs treated with 8% of garlic extract. In the sanitary status of the guinea pigs was not registered the presence of salmonella, the bacterial population (E. coli), as well as the parasite load (Protozoans and Nematodes) were significantly reduced with the use of garlic extract. The highest yield was obtained with the inclusion of 8% of garlic extract reaching a benefit / cost of 1.22. The use of garlic extract influenced the productive performance of these animals. Therefore, it is recommended to use 8% of garlic extract in guinea pigs during the growth-fattening stage because the lowest cost of production and the best benefit / cost have been recorded.
