The rhea (Rhea americana) is an important wild species that has been highlighted in national and international livestock. This research aims to analyse embryo-foetal development in different phases of the respiratory system of rheas. Twenty-three embryos and foetuses were euthanized, fixed and dissected. Fragments of the respiratory system, including the nasal cavity, larynx, trachea, syrinx, bronchi and lungs, were collected and processed for studies using light and scanning electron microscopy. The nasal cavity presented cubic epithelium in the early stages of development. The larynx exhibited typical respiratory epithelium between 27 and 31 days. The trachea showed early formation of hyaline cartilage after 15 days. Syrinx in the mucous membrane of 18-day foetuses consisted of ciliated epithelium in the bronchial region. The main bronchi had ciliated epithelium with goblet cells in the syringeal region. In the lung, the parabronchial stage presented numerous parabronchi between 15 and 21 days. This study allowed the identification of normal events that occur during the development of the rhea respiratory system, an important model that has not previously been described. The information generated here will be useful for the diagnosis of pathologies that affect this organic system, aimed at improving captive production systems. |

This study aimed to evaluate the intake and nutrient digestibility, water, and nitrogen balance of Santa In?es crossbred ewes under confinement receiving reductions in the water supply. Thirty-two Santa In?es crossbred ewes, at an average body weight of 32.2 ± 7.4 kg and age of 2.3 ± 0.99 years, were distributed in a completely randomized design, with four treatments, and eight animals per treatment, the treatments were 100%, 80%, 60%, and 40% of ad libitum water. Nutrient intake and digestibility, water and nitrogen balance, and perfor- mance were evaluated. The reductions in the water supply did not promote significant alterations, in the nutrient intake, or apparent digestibility of the animals (P > 0.05). A linear decreasing effect was observed for free water intake (P < 0.001), total water intake (P < 0.001), total urine output (P = 0.008), water excreted via urine (P = 0.006), water excreted via feces (P = 0.006), total water losses (P < 0.001), water absorbed (P < 0.001), and nitrogen excreted via feces (P = 0.002). The water and nitrogen balance and performance were not influenced by water offers (P > 0.05). It was concluded that water offers of up to 40% of ad libitum intake, do not promote negative effects on intake and apparent nutrient digestibility, mineral intake, nitrogen balance, and water balance in Santa In?es ewes. |
