This experiment was conducted to investigate the effects of coated γ-aminobutyric acid (GABA) on the growth performance, rumen fermentation parameters, and serum hormone levels of lamb. A total of 60 healthy weaned lamb were randomly divided into four groups with three replicates per group and five lambs per replicate. Lambs in each group were fed 0 (control group), 100 (GABA1 group), 150 (GABA2 group) and 200 mg/kg (GABA3 group) coated GABA of diet, respectively. The pre-feeding period was one week and the formal experiment period was four weeks. The results showed that compared with the control group, the final weight and average daily gain of lambs in GABA2 group were significantly increased (P<0.05), and the ratio of feed to gain was significantly decreased (P<0.05). The levels of cholecystokinin in all coated GABA were significantly decreased (P<0.01). The level of neuropeptide Y in GABA2 group and GABA3 group was significantly increased (P<0.05), and the level of norepinephrine was significantly decreased (P<0.05). The level of serotonin in GABA2 group was significantly increased (P<0.05), and the level of dopamine was significantly decreased (P<0.05). The activity of alkaline phosphatase in serum of lambs in GABA2 group was significantly increased (P<0.05), and the activity of glutamic oxalacetic transaminase was significantly decreased (P<0.05). Rumen mycoprotein content in GABA2 group was significantly increased (P<0.05). The study indicates that coated GABA can promote the growth performance of lambs, improve rumen mycoprotein synthesis, improve serum hormone to relieve weaning stress, and the optimal supplemental level is 150 mg/kg.

A class of high-order nonlinear integral-differential singular perturbation systems' steady state Robin problem was discussed. Firstly, the theory of differential inequality for the high-order nonlinear nonlocal differential system was built. Then, the outer solution to the problem was structured and the boundary layer corrective term was obtained by means of the local coordinate system. Thus the formal asymptotic expansion of the solution was got. Finally, the uniform validity of the asymptotic expansion of the solution was proved with the theory of differential inequality.

A class of nonlinear fractional-order perturbed higher-order differential models was considered. Firstly, under suitable conditions, the outer solution to the original problem was obtained with the perturbation method. Then by means of the stretched variable, the composite expansion method and the theory of power series, the first and second boundary layer correction terms were constructed and the formal asymptotic expansion was obtained. Finally, with the theory of differential inequalities the asymptotic behavior of the solution to the problem was studied and the uniform validity of the asymptotic estimate expression was proved.

A class of Robin problems of nonlinear catalytic reaction differential equations were studied. Firstly, under the suitable conditions, the outer solution to the original Robin problem was obtained with the perturbation method. Then by means of the stretched variable and the power series, the 1st and 2nd boundary layer corrective terms were constructed respectively, and the formal asymptotic expansion was structured. Finally, based on the theory of differential inequalities the formal asymptotic expression of the solution to the Robin problem was given. Finally, the uniform validity of the asymptotic expression of the solution to problem was proved. [ABSTRACT FROM AUTHOR]
