The livestock sector must urgently seek for more efficient and sustainable productivity and meet higher standards of animal welfare. The negative effects of climate change on animal health and welfare are the consequence of the combined changes in atmospheric temperature, rainfall, and frequency and magnitude of extreme weather events that can be both direct and indirect.

In addition, the potential that Mexican native strains can have for their use in the control of the grasshopper Sphenarium purpurascens (an edible insect but that behaves as a pest in several crops). In the present investigation, the mortality of two instars (or stages) of S. purpurascens in vitro plus the adult phase, was evaluated by applying bio-preparations of the MA-Bb1 strain in porous materials as support. The highest corrected mortality CM% and the highest specific speed of death K(d–1) of the orthopter for the different instants, as well as for the adult of S. purpurascens was presented in the bio-preparation (Zeolite + Diatomite + B. bassiana) at a concentration of 1 × 108 conidia mL–1, presenting a viability of 89,1%.

Fivehundred ten heifers (Zebu, European and its crosses) were randomly assigned to six pens divided in two shade areas: T1) three pens with 100 heifers per pen (shade area: 2.7 m2/animal), and T2) three pens with 70 heifers per pen (shade area: 3.7 m2/animal). Fifteen blood samples of each genotype per pen were collected three times (days 1, 28 and 66) during the study. To analyze metabolites, electrolytes and thyroid hormones, serum samples were used, while for hematological components fresh blood. Data was analyzed under a 2×2 factorial arrangement in a completely randomized design with repeated measurements. The temperature-humidity index averaged 81.7 units. In T1, both genotypes showed similar glucose concentration (P < 0.05), but in T2 glucose concentrations was higher in Zebu (P < 0.05). The urea level were lower (P < 0.05) in T2 than in T1. The Na+ level in T1 was higher (P < 0.05) than in T2. The Cl– in T1 was lower (P < 0.05) than in T2. The hormone T3 showed lower concentration (P < 0.05) in T1 compared to T2. No differences were detected for Htc and Hb between genotypes within T1 (P < 0.05), but they were higher in T2 for Zebu heifers (P < 0.05) than Europeans.
