This study aimed to characterize the ovarian follicular dynamics in locally adapted Curraleiro Pé-Duro cows and heifers. Cyclic heifers (n =12) and non-lactating, multiparous cows (n = 11) were examined daily by ultrasonography for two consecutive ovulations (an estrous cycle). Follicles >...

O principal desafio da suinocultura brasileira é adequar a ambiência dos edifícios de alojamento às variações climáticas nas regiões produtoras, uma vez que estas influenciam tanto os indicadores zootécnicos de desempenho dos animais como as emissões de gases.

An initial model was developed to predict the volume and composition of sow manure in the gestation and maternity phases, based on studies. The model was validated using data from a project (14 months) on farms in southern Brazil. Water and feed flows were used as in...

Mealworm control has been a challenge for the broiler production´s system. The technical, economic, environmental and public health impacts are difficult to quantify, but economic losses are certain, considering that the adult insect and larvae, causes damage to the structure of th...

Mealworms control using chemical insecticides have been faces challenges, as a developed resistance and concerns about the sustainability of the poultry production system. The experiment objective was to evaluate the insecticidal potential of plants extracts, as an alternative to chemical compoun...

The composition of soybean meal varies according to the supplier, and some production processes remove lecithin, which has a significant impact on the production of pelleted diets and may result in losses in production capacity. This is all aggravated by the tendency to reduce ...

There is a discrepancy regarding the nutritional requirements of laying hens, making it difficult to prepare and establish adequate nutritional programs. The objective of this study was to compare two tables of nutritional requirements for laying hens and two sources of limestone on...
