Macromineral requirements for maintenance and growth in male and female hair sheep.

A better understanding of the nutritional requirements of sheep, especially in terms of minerals, is crucial for improving production. We estimated the net requirements for Ca, P, K, Mg, and Na for gain (NCa, NP, NK, NMg, and NNa) and maintenance (NCa, NP, NK, NMg, and NNa) in male and female hair sheep. Six datasets with 248 individual records of hair sheep (139 non-castrated males, 75 castrated males and 34 females) were used to estimate the net macromineral requirements for gain.

Maintenance and Growth Requirements in Male Dorper × Santa Ines Lambs.

The aim of this study was to estimate the energy and protein requirements for maintenance and growth of lambs. A total of 35 crossbreed Dorper × Santa Ines lambs [31 ± 1.28 kg of initial body weight (BW) and 4 months old] were distributed in a completely randomized design with three treatments groups (, 30 and 60% of feed restriction).

Legal aspects of public health: difficulties in controlling vector-borne and zoonotic diseases in Brazil.

In recent years, vector-borne and zoonotic diseases have become a major challenge for public health. Dengue fever and leptospirosis are the most important communicable diseases in Brazil based on their prevalence and the healthy life years lost from disability. The primary strategy for preventing human exposure to these diseases is effective insect and rodent control in and around the home.
