- 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 ...

- Abstract:
- ... The check-all-that-apply (CATA) technique was used to determine lamb management practices and some constraints faced by resource-limited communal sheep farmers in the Sour veld and Sweet veld regions. 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:
- ... The aim of this research was to study the myostatin gene (MSTN) in Russian Stavropol Merino sheep and compare them with Merino sheep from New Zealand (NZ). Thirty rams of the Stavropol Merino breed and ten NZ Merinos were investigated. In order to detect sequence variation in MSTN, enrichment and sequencing of targeted DNA fragments was undertaken using NimbleGen technology. Nucleotide sequence va ...

- 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 ...

Genetic characterization and diversity of local goat breeds (Naine de Kabylie, Arbia, Mekatia, and M’zabite) raised in Algeria (n = 224) were investigated by eighteen microsatellite markers recommended by FAO (2011). A total of 450 alleles were detected in this study. The mean values of polymorphic information content, observed heterozygosity and expected heterozygosity were 0.93, 0.84, 0.94, resp ...

They revealed bilateral occlusion of the eyelids and were unresponsive to external visual stimuli and were disoriented when walking. A post-mortem examination revealed bilateral occlusion of the eyelids and, microscopically, total or partial absence of the lens was observed. Blood samples fro ...

Forty Pelibuey × Katahdin intact male lambs (23.0 ± 1.8 kg initial shrunk weight) were used in an 84-day feeding trial (5 pens per treatment, randomized complete block design) to evaluate crude protein level (110, 140, 170, and 200 g/kg diet DM) in isocaloric diets (2.03 Mcal NEm/kg) on finishing-phase growth performance, dietary energetics and carcass traits. Increases in protein levels were acco ...

Modeling of its annual dynamics, which is lacking, can contribute to delineate integrated management strategies. We sampled ked density along a one-year period in two sheep farms of Northwest Patagonia, Argentina. In one farm with semi-i ...
