Surviving the Heat: Genetic Diversity and Adaptation in Sudanese Butana Cattle

Guilherme B. Neumann, Paula Korkuć, Siham A. Rahmatalla, Monika Reißmann et autres

Background: Butana are native Sudanese Bos indicus cattle that are well adapted to arid environments and valued for their relatively high milk performance and resilience under harsh conditions. Despite their adaptive advantages, Butana cattle face the risk of genetic erosion due to …

Are SNPs Linked to Somatic Cell Score Suitable Markers for the Susceptibility to Specific Mastitis Pathogens in Holstein Cows?

Uwe Müller, Eva M. Strucken, Jian Gao, Siham A. Rahmatalla et autres

Mastitis in cattle is often caused by microorganism infections in the udder. The three most common pathogens are esculin-positive streptococci (SC+), coagulase-negative staphylococci (CNS), and Escherichia coli (E. coli). In a previous study, 10 SNPs were associated with somatic cell score and …

Whole‐genome SNP genotyping unveils ancestral and recent introgression in wild and domestic goats

Neža Pogorevc, Arsen Vladimirovich Dotsev, Maulik R. Upadhyay, Edson Sandoval‐Castellanos et autres

After the domestication of goats around 10,000 years before the present (BP), humans transported goats far beyond the range of their wild ancestor, the bezoar goat. This brought domestic goats into contact with many wild goat species such as ibex and markhor, …

Effect of Grazing Management and Watering Regimen on Sudan Desert Lambs’ Body Weights

H. A. Salih, Faisal M. El-Hag, Claudia Kijora, A. M. Abu-Nikhaila et autres

This study utilized mature Sudan Desert ewes (Ovis aries) at a village in Sheikan locality, North Kordofan State, within the semi-desert ecological zone of Sudan. Sixty ewes were randomly assigned to grazing and watering regimen combinations in a factorial arrangement of treatment …

Adaptation of Desert Goats to Solar Heat Load and Water Restriction as Indicators of Climate Change Under Semi – Arid Condition

Hind Abdelrahman Salih, I. Bushara, Siham A. Rahmatalla

This experiment was conducted at Elobeid ARC Farm, North Kordofan State, Sudan, and covered hot summer, rainy, winter, and warm summer seasons for 310 days. Thirty-six non-pregnant Desert goats were used in this experiment. One group was randomly allocated to a shaded …

Whole-Genome Sequencing Data Reveal New Loci Affecting Milk Production in German Black Pied Cattle (DSN)

Paula Korkuć, Guilherme B. Neumann, Deike Hesse, Danny Arends et autres

German Black Pied (DSN) is considered an ancestral population of the Holstein breed. The goal of the current study was to fine-map genomic loci for milk production traits and to provide sequence variants for selection. We studied genome-wide associations for milk-production traits …

Genetic analysis of growth curve in Moghani Sheep using Bayesian and restricted maximum likelihood

Azar Rashedi Dehsahraei, Mostafa Ghaderi‐Zefrehei, Farjad Rafeie, Sonia Zakizadeh et autres

This study was conducted to predict the genetic (co)variance components of growth curve parameters of Moghani sheep breed using the following information: birth weight (N = 7278), 3-mo-old weight (N = 5881), 6-mo-old weight (N = 5013), 9-mo-old weigh (N = 2819], …

731. Pairwise principal component analysis of African goat breeds identifies loci involved in meat and/or milk production

Siham A. Rahmatalla, Danny Arends, Getinet Mekuriaw Tarekegn, R. Onzima et autres

The selection process in Africa, both environmentally and human-driven, is expected to have led to distinctive variations on the genome between milk and meat goat breeds. We used genotypic data from the caprine 50k Illumina BeadChip to assess the genetic differentiation between …
