“…Myosin-1a (MYO1A) gene is known as a candidate gene associated with skin pigmentation in cattle [69]. As reported previously, skin pigmentation is highly related to the regulation of body temperature regulation [101,102]. In the enterocyte microvillus, the MYO1A was considered the most abundant actin-based motor protein that interactsinteracting with the apical membrane via a highly basic C-terminal tail domain [103].…”

Thermal stress due to extreme changes in the thermal environment is a critical issue in cattle production. Many previous findings have shown Many evidences showed a decrease in feed intake, milk yield, growth rate, and reproductive efficiency of the cattle when subjected to thermal stress. Therefore, sSelecting thermo-tolerant animals are is therefore the main primary goal of the efficiency of breeding programs to reduce those adverse impacts. The recent advances in molecular genetics have provided significant breeding advantages that allow the identification of molecular markers in both beef and dairy cattle breeding, including the use of marker-assisted selection (MAS) as a tool in selecting superior thermo-tolerant animals.Single-nucleotide polymorphisms (SNPs), which can be detected by DNA sequencing, are desirable DNA markers for MAS due to their abundance in the genome's both coding and noncoding regions of the genomes. MTill date, many SNPs in some genes (e.g., HSP70, HSP90, HSF1, EIF2AK4, HSBP1, HSPB8, HSPB7, MYO1A, and ATP1A1) in various breeds of cattle have been analyzed to play have key roles in many cellular activities during thermal stress and protecting cells against stress, thereby beingmaking them potential candidate genes for molecular markers of thermotolerance. TIn this review , we highlighted the associations of SNPs within these genes with thermotolerance traits (e.g., blood biochemistry and physiological responses), which could imply suggesting their potential use as MAS in thermotolerant cattle breeding.

“…As an important trait, coat color has a certain selective effect on the production traits of cattle. It has been reported that the weight of cattle with a deep coat color is significantly higher than that of cattle with a light coat color in high-temperature environments [55]. In white pigs, the birth weight of piglets with KIT dominant genotype II was significantly higher than that of piglets with the recessive i allele.…”

Coat color and birth weight, as easily selected traits in cattle, play important roles in cattle breeding. Therefore, we carried out a genome-wide association study on birth weight and coat color to identify loci or potential linkage regions in 233 Simmental × Holstein crossbred beef cattle. The results revealed that nine SNPs were significantly associated with coat color (rs137169378, rs110022687, rs136002689, Hypotrichosis_PMel17, PMEL_1, rs134930689, rs383170073, rs109924971, and rs109146332), and these were in RNF41, ZC3H10, ERBB3, PMEL, and OR10A7 on BTA5. Interestingly, rs137169378, rs110022687, rs136002689, Hypotrichosis_PMel17, and PMEL_1 showed strong linkage disequilibrium (r2 > 0.8) and were significantly associated with coat color. Notably, Hypotrichosis_PMel17 and PMEL_1 were located in the gene PMEL (p = 2.22 × 10−18). Among the five significant SNPs associated with coat color, the birth weight of heterozygous individuals (AB) was greater than that of homozygous individuals (AA). Notably, the birth weight of heterozygous individuals with Hypotrichosis_PMel17 and PMEL_1 genotypes was significantly greater than that of homozygous individuals (0.01 < p < 0.05). Interestingly, the two loci were homozygous in black/white individuals and heterozygous in gray/white individuals, and the birth weight of heterozygous brown/white individuals (43.82 ± 5.25 kg) was greater than that of homozygous individuals (42.58 ± 3.09 kg). The birth weight of calves with the parental color (41.95 ± 3.53 kg) was significantly lower than that of calves with a non-parental color (43.54 ± 4.78 kg) (p < 0.05), and the birth weight of gray/white individuals (49.40 ± 7.11 kg) was the highest. Overall, PMEL appears to be a candidate gene affecting coat color in cattle, and coat color may have a selective effect on birth weight. This study provides a foundation for the breeding of beef cattle through GWAS for coat color and birth weight.

“…As illustrated in the above applications, the physical and spectral properties of hair and haircoats are inputs to thermodynamic models that predict energy exchange between the animal and the environment [31][32][33][34]. For example, haircoat density acts as a resistance to wind penetration into the haircoat, and thus affects the boundary condition.…”

The physical properties (hair diameter, hair length, haircoat depth and haircoat density) and spectral properties (absorptivity, reflectivity, transmissivity) of the hair and haircoat of cattle are inputs to heat and moisture exchange between the skin surface and the surrounding environment, and thus play a critical role in body temperature regulation. Physical and spectral properties of haircoats also play an important role in protecting the skin against penetration of ultraviolet radiation. The focus of this review is to identify accurate and consistent measurement procedures of these properties. Additionally, the paper shows the utilization of the properties on heat exchange models and their implications on voluntary thermoregulation of cattle. To highlight the effects and benefits of haircoat color vis-à-vis solar radiation and its implication on ecological habitation, a brief explanation is provided using polar bears (white haircoat in a cold environment) and black goats in a hot desert environment.
