Nutritional contribution of green hydroponic forage in the feeding of criollas x Nubian crossed goats
The objective of this work was to evaluate the incorporation of Hydroponic Green Forage (FVH) in diets for goats. Four crossed goats (criolla x Nubian) were used in an experimental cross design (croos over) with four repetitions. The FVH used was Avena sativa. The diets supplied were: 100% CN hay (D0) and CN hay + 1.2 Kg FVH / goat / day (D1). In all treatments, CN hay was delivered ad-libitum. Two experiments were carried out: I) determination of total dry matter consumption (CTMS), CN hay consumption (CMSHCN), FVH consumption and apparent total digestibility in vivo of the dry matter consumed. II) Determination of ruminal pH and in situ ruminal degradability of FVH and CN hay. The CTMS of D1 was higher (p <0.05) than D0 and there was a linear increase (p <0.05) in the consumption of NDF, PB and MS. The CMSHCN did not register differences (p> 0.05) between both treatments. The treatment that included FVH, increased linearly (p <0.05) the total digestibility of the diet consumed. The in situ ruminal degradability of the HF of the FVH for the 48 h of ruminal incubation did not verify differences (p> 0.05) between the aerial part and the radicular part. The in situ degradability of CN hay for 48 h of its rumen incubation was higher (p <0.05) in the D1 diet. The average ruminal pH of the day, the area under the pH 6 threshold curve and the hours with pH below the threshold, did not verify differences (p> 0.05) between the diets tested. In conclusion, the FVH is a valid alternative in the feeding of goats, acting as an improvement in consumption, ruminal degradability, total digestibility and nutritional value of forage reserves of low quality.
