Abstract The aim of this study was to determine the effect of increasing total solids (TS) in the liquid diet during the preweaning phase on mammary gland development in dairy heifers. The increase in TS was obtained with the addition of milk replacer powder to whole milk. Crossbreed Holstein-Gyr heifers (n = 60) were distributed in 4 treatments with different TS concentrations: 13.5% (n = 15), 16.1% (n = 15), 18.2% (n = 15), and 20.4% (n = 15). The liquid diets were provided from 5 to 55 d of age. From 56 to 59 d of age, the total amount of liquid feed was reduced by half. Heifers were weaned at 60 d and monitored until 90 d of age. Ultrasound mammary gland evaluations were performed weekly between 5 to 11 wk of age, using a B-mode ultrasound equipped with microconvex transducer at a frequency of 6 MHz. In those same weeks, the manual palpation of mammary parenchyma (PAR) was performed. Increased TS concentration of liquid diet during the preweaning period increased body weight of heifers, but did not alter PAR growth and the deposition of adipose tissue in the mammary gland evaluated by ultrasonography. The oval-shaped structure of PAR was altered after 2 mo of age. In the evaluated period, PAR growth was isometric with respect to the body growth rate. Palpation scoring of PAR had a strong correlation with the ultrasound evaluation of the PAR. |

ABSTRACT - The objective of this work was to identify, by molecular analysis, the species of the genus Helicoverpa in corn, soybean, and lucerne Bt and non-Bt crops, in central Argentina. A total of 1,343 carterpillars were analyzed by PCR-RFLP. Helicoverpa zea was the only species detected on non-Bt and on most Bt corn hybrids. The species H. gelotopoeon predominated on non‑Bt soybean and on lucerne, and H. zea larvae occurred in low proportion. Bt soybean did not show Helicoverpa spp. infestations. The exotic H. armigera was not found, though adult moths of this species were light-trapped in a complementary sampling. RESUMO - O objetivo deste trabalho foi identificar, por análise molecular, as espécies do gênero Helicoverpa nas lavouras - Bt e não Bt - de milho, soja e alfafa, no centro da Argentina. Um total de 1.343 lagartas foram analisadas por PCR-RFLP. A espécie H. zea foi a única detectada no milho não Bt e na maioria do Bt. A espécie H. gelotopoeon predominou na soja não Bt e na alfafa, mas H. zea ocorreu em baixa proporção. A soja Bt não apresentou infestações por Helicoverpa spp. A exótica H. armigera não foi encontrada, porém, mariposas adultas dessa espécie foram capturadas com armadilha luminosa em uma amostragem complementar. |
