The objective of this work was to evaluate the effect of adding 8.4, 18.8, 31.2, and 48.3% of saltbush hay, in diets fed to 1/2 Boer goats, on nutrient intake and digestibility, body weight gain, and feed conversion

Thirty two male goats,  with average body weight  (BW) of  20.82 ± 1.46 kg were used in a randomized  complete block design that lasted for 80 days. Diets were fed at 9:30 and 15:30 h. The animals were housed  in individual stalls and their weights were recorded every 15 days after 18 hours of fasting. At day 61, 24  animals  were housed in  metabolic  cages and plastic  bags  were used  for  feces collection  to  estimated  ingredient  digestibility.  The addition of  saltbush hay in the diets  promoted a quadratic response on DM intake. The minimum and maximum intakes of DM (53.11 and 104.27 g.kg-0, 75) were observed in the diets  with 8.4 and 48.3% of saltbush hay, respectively. The total and daily BW gain had a linear behavior, with the highest  values  of  207.5  kg  and  12.42  g.day-1,  respectively,  for  diets  with  31.2%  of  saltbush  hay.  No significant difference (P>0.05) was observed for feed conversion, averaging 5.77. There was a linear effect  on digestibility of DM and CP, where the lowest digestibility was found with 8.4% saltbush hay and 74.9% of  spineless cactus for both variables. There was no significant difference in the digestibility of OM, TC, NFC, and NDF, averaging 74.72, 75.45, 93.74, and 50.66%, respectively. Saltbush hay proves to be a very viable alternative to feed goats, especially in semi-arid regions, since its use up to 48.3% increases the digestibility  and nutrient intake and promotes BW gain of 140 g.day-1 in ½ Boer goats.
