Infrared thermometry for detecting estrus and pregnancy in Holstein cows.

Efficient reproductive management is paramount in enhancing the productivity and welfare of dairy cows. This study investigates the effects of pregnancy status, seasonal variations, and diurnal shifts on the body temperature of different body parts in dairy cows. Using a structured approach, cows were categorized based on pregnancy status (pregnant vs.

Genomic characterization, phylogenetic and expression analysis of foraging gene in Apis mellifera.

The genomic characterization of the foraging gene and its expression analysis are required to better understand the behavior of honey bees (Apis mellifera). The present study performed a genome-wide characterization of the foraging gene, analyzing its physicochemical properties, phylogenetic features, and expression. An in silico analysis was carried out to characterize the foraging gene and the motifs and conserved domains of the encoded protein to predict its physicochemical properties.

Cysteamine administration in lambs grazing on mountain pastures: Effects on the body weight, antioxidant capacity, thyroid hormones and growth hormone secretion.

This study aimed to evaluate the effects of intravenous injection of cysteamine (CS) on body weight (BW), growth hormone (GH), thyroid hormones (TH) secretion, and antioxidant status of growing lambs grazing on mountain pastures. Fifteen lambs (3-4 months of age) were randomly allocated into three experimental groups which received different dosages of CS: 0, 20, and 50 mg/kg BW . The CS was injected on the 1st, 10th and 20th days of the experiment to the lambs through the jugular vein.

The pattern of HSP70 gene expression, flight activity and temperature in Apis mellifera meda colonies.

Honey bees produce heat shock proteins (HSPs) following biotic and abiotic stressors to protect cells from damage. In the current study, the pattern of HSP70 gene transcription, foraging, and temperature inside and outside the hive and their association in Apis mellifera meda colonies during Ziziphus blooming period were investigated. Therefore, the number of bees entering the hive, temperature inside and outside the hive were recorded in six colonies at different times of the day.

No polymorphism of melatonin receptor 1A (MTNR1A) gene was found in Markhoz goat.

Melatonin is the main hormone of seasonal breeding in sheep and goat which has an effect on reproductive organs via its receptors. Studies have shown that mutations in melatonin receptor 1A (MTNR1A) gene are related to litter size as well as the ovulation rate in sheep and goats. In this study, polymorphism of two loci in MTNR1A melatonin receptor gene was studied in order to survey their relationship with litter size in Markhoz goats.

Differential Expression of the Alpha S1 Casein and Beta-Lactoglobulin Genes in Different Physiological Stages of the Adani Goats Mammary Glands.

Background: Milk proteins genes have been the focus of the researches as the candidate target genes that play a decisive role when animal breeding is desired.

Objectives: In the present study, the transcriptional levels of Beta-lactoglobulin () and Alpha S1 casein () genes were investigated during prenatal, milking and drying times in mammary glands of the Adani goats which showed high and low breeding values.

Materials And Methods: The breeding values of the animals were estimated first by applying multi-trait random regression model.
