Physiological and bioclimatic aspects of goats in semi-arid regions

Abstract

A caprinocultura apresenta importante papel econômico-social para a região Nordeste, por suprir as populações de baixa renda de proteína de valor biológico. A região possui o maior rebanho caprino do Brasil, resultante da adaptação destes animais às condições climáticas locais. As diferentes respostas do animal às peculiaridades de cada região são determinantes no sucesso da atividade pela adequação do sistema produtivo às características do ambiente e ao potencial produtivo dos animais. Nesta revisão serão abordados alguns aspectos fisiológicos e bioclimáticos da caprinocultura nas condições semiáridas.Palavras chave: bioclimatologia, equilibro térmico, ruminantes Physiological and bioclimatic aspects of goats in semi-arid regionsABSTRACT. The goat provides important economic and social role in the Northeast, by supplying the low-income populations of protein biological value. The region has the largest goat herd in Brazil, resulting from the adaptation of these animals to local climatic conditions. The different responses of the animal to the peculiarities of each region are key to the success of the activity by adapting the production system to the characteristics of the environment and the productive potential of animals. In this review we discuss some aspects of the physiological and bioclimatic the goat farming in semi-arid conditions.

On-farm welfare assessment in dairy goats in the Brazilian Northeast

“…In the first and second level welfare assessments, welfare levels, lactating goats (L) showed signs of thermal stress as panting as a likely attempt to maintenance of homeothermia probably due to higher physiological demands (Speakman, 2008). However, if this behavior is performed for a longer period it may interfere with food intake and rumination (Vieira et al, 2016), causing weight loss and reduced milk yield in dairy goats (Brasil et al, 2000). Thermal stress in these animals occurs when goats are submitted to temperatures above thermal comfort zone (20-30°C) or critical zone (> 34°C) (Baêta and Souza, 2010) and to relative humidity below 40% or above 80% in tropical climates (Farm, 1998).…”

Analysis of the potential geographical indication for ovine and caprine from the semiarid piauiense

“…The productive potential and adequacy of the productive system to the climatic conditions of semi-arid regions were highlighted in the work of Vieira et al (2016) when discussing bioclimatic and physiological factors for ovine and caprine production in semi-arid regions. Neto (2022), also addressing the adaptive perspective of herds in these regions, sought to analyze the adaptive physiological response of exotic ovine and caprines herds in experiments carried out in Brazil over 10 years (2010 to 2020).…”

Parâmetros produtivos e comportamentais de cabritos alimentados com enzimas exógenas na dieta

“…Uma forma de criar condições mais favoráveis para digestibilidade e a degradabilidade ruminal das fibras, proteínas e amidos é a utilização de enzimas exógenas (Vieira et al, 2016). Além de melhorar o desempenho, visa também reduzir os custos da produção, através da redução da quantidade de insumos obtidos pela otimização do aproveitamento dos nutrientes presentes na dieta (Marcondes et al, 2009).…”
