Abstract:
... The present study was carried out to assess the capacity of Morada Nova (MON) and Santa Inês (SIN) hair sheep breeds to maintain homeothermy and its relation with semen quality in a tropical climate. Sixteen rams (MON = 7 and SIN = 9) were assessed for 12 months. During summer and spring, the Temperature-Humidity Index values surpassed the level indicative of thermal stress, and sweating, respirat ...

A total of 107 respondents were involved in the study. Data generated from CATA was analysed using the XLSTAT 2016 software. Results showed that the majority of the households were headed by men (75. ...

Abstract:
... Parent-of-origin effects are often excluded from models used for estimating of additive and non-additive genetic variances. Omission of parentally-linked genetic factors, such as imprinting, from statistical models has potential to induce profound bias during the estimation. In this study, parent of origin variance for productive and reproductive traits in Lori-Bakhtiari sheep was estimated using ...

Abstract:
... Deprivation of social contact through solitary confinement has the potential to induce stress in farm animals. Current evidence that housing-induced stress contributes to suboptimal welfare, growth performance and meat quality in sheep is neither ubiquitous nor convincing. This study, therefore, investigated the effect of social stress, as induced by single-pen (isolated) and paired-pen (socially ...
