There is a surplus of Atriplex nummularia Lindl. grazing that can be used as animal feed. This material was harvested to assess the effects on intake, growth, and carcass characteristics of kids. Atriplex replaced alfalfa hay (Medicago sativa L.) in a proportion of 0%, 10%, 20%, 30%, and 40% for 60 creole kids weighing 13 kg and was assigned to the diets in a completely randomized design. The process was conducted from March to May. Two males and two females were used from each group to evaluate individual nutrient intake. Height at withers, thoracic diameter, and weight change were evaluated in all the animals. The carcasses of four females per group were evaluated. Offered and rejected hay diet samples were chemically analyzed. Atriplex hay crude protein (CP), metabolizable energy (ME), chlorine (Cl), and sodium (Na) contents were 20.20%, 1.99 Mcal kg -1 , 4.78%, and 6.47% respectively. Hemicellulose (Hc), ash intake, height at withers, thoracic diameter, and carcass component, except for the kidney, were not different (P > 0.05) among treatments. Over 20% of A. nummularia hay content in the diet caused an increase in mineral consumption (P < 0.05). Total body weight gain decreased (P < 0.05) by adding 20% or more A. nummularia hay content in the diet. However, adding up to 20% of A. nummularia hay in the diet did not produce a negative effect and higher percentages decreased weight gains attributable to the high Na and Cl content.

The effect of long-term administration of acetaminophen to rats on the dietary protein utilization was investigated using protein-sufficient and protein-deficient diets. Fat digestibility, food efficiency and some hepatic parameters were also determined. Results showed that there was a significant decrease in the nitrogen metabolic utilization in the protein-sufficient treated animals compared to the untreated group (0.59 ± 0.03 vs. 0.75 ± 0.03, p < 0.001). The protein-deficient diet and the administration of the drug resulted in lower nitrogen metabolic utilization in either of the two metabolic balances (days 4–11 and 36–42). These changes were not accompanied by variations in the nitrogen digestibility coefficient.
