The present study aims to examine the effect of goats on abnormal behaviors of horses. Therefore, horses and goats were monitored for 45 d. As a result, the abnormal behaviors of horses such as front feet playing, crib-biting object, and box walking behaviors were affected positively by the goats, while there was no effect on other abnormal behaviors.

This study was aimed at determining the effects of different doses of thyme essential oil (TEO) and rosemary essential oil (REO) incorporated into broiler rations on performance parameters, including body weight gain, feed intake and feed conversion rate, as well as on the quality criteria of breast and drumstick meat. As a result, dietary supplementation with TEO and REO was determined to have a limited effect on performance parameters but to improve the microbial quality of meat.

Genes enriched in sensory perception were positively selected via selection signature analysis between wild Asiatic mouflon and domesticated Hu sheep. Among them, RDH5 is one of the key enzymes in the synthesis of retinoic acid (RA), which is related to human retinopathy. The c.722T>C/p.M241T mutation of RDH5 affects retinol dehydrogenase activity in the domestication process of sheep.

The fatty acid (FA) composition of cattle is correlated with cardiovascular diseases in humans. These FAs come from ruminal biohydrogenation; however, this process also produces FAs that can provide benefits to human health. Sex and diet can affect the FA profile of the meat. The meat FAs of cattle in feedlot systems are different due to diet differences. This study aimed to evaluate the effect of sex on the FA profile and meat quality of feedlot cattle fed a whole shelled corn diet.

Globally, water buffalo livestock farming accounts for approximately 200 million animals; the use of precision livestock farming (PLF) technologies, which are becoming widespread in dairy cattle livestock farming, is explored for water buffalo livestock farming by adapting the system for the use of water buffalo enterprises. In this study, the possibilities of using PLF technologies in water buffaloes are presented by surveying the breeders and by SWOT analysis according to the survey results.

The present study addressed the interactive effects of concentrate levels (low (40 %) and high (60 %)) and plant (pomegranate, garlic, or sunflower) oils on in vitro rumen fermentation kinetics. Results indicated that the interaction of diet and oils had no significant effect on in vitro gas production parameters. Data suggested no effect for unconventional oil on in vitro rumen fermentation in either high or low concentrate diets.

This publication aims to describe the physiology of the mammary gland and its immune mechanisms and to approximate their connection with potential mastitis resistance genes. It describes various options for mastitis elimination and focuses on genetic selection and a closer specification of resistance genes to mastitis.

This study confirmed that mtDNA could make a significant contribution to cattle farming in both theory and practice. In theory, even if they were domesticated in different geographical areas, the patterns of crossbreeding between taurine and indicine were detected in Anatolian cattle at a low frequency. In practice, pedigree records could be revised in terms of admixture level and species-specific haplotypes of taurine and indicine by the farmers via molecular studies such as mtDNA.

This study aimed to understand the effects of adding low-dose oxytocin hormone into ram semen on the pregnancy rate and reproductive efficiency of sheep. A total of 53 out of 122 Chios ewes were inseminated with oxytocin hormone content, and successful pregnancy was achieved 90.56 % of them. In examination of the pregnancy rate, one of the indicators of reproductive performance, the difference between the groups is statistically significant (p = 0.046; p ≤ 0.05).

The application of antibiotics is being regulated continuously. Therefore, natural agents are being investigated that aim to strengthen the defense system of poultry. In our study, capsanthin was applied to investigate its effect on immune response under lipopolysaccharide immunization. Based on our results, capsanthin decreased the levels of pro-inflammatory cytokines at both mRNA and protein levels, which suggest the positive effects of capsanthin during inflammation in broiler chickens.

The results of this study found that a mutation site of the MLPH gene was associated with the white-feather phenotype of quail, which provided a theoretical basis for the study of quail feather color change and quail reproduction.

The aim of this paper was to evaluate semen parameters from Czech Fleckvieh bulls used in artificial insemination (AI) in the Fleckvieh population. We analyzed 1029 samples from 46 Fleckvieh bulls from one AI station. Semen from the bulls was collected once a week, which is not usual in other AI stations. We also assessed sperm quality parameters of ejaculate before freezing and after thawing. The ejaculate parameters were evaluated in relation to the collection season and the age of the bulls.

We present a novel study of the effect of bta-miR-33a on lipid metabolism in bovine mammary epithelial cells (BMECs). The correlation between bta-miR-33a and target gene ELOVL6 is also verified by a luciferase reporter assay. We show that bta-miR-33a directly inhibits the expression of ELOVL6 in BMECs, altering the mRNA expression of relative genes. This suggest that bta-miR-33a regulates lipid metabolism by targeting ELOVL6, which might be a potential molecular marker of milk fat composition.

This study aimed to determine the effect of fenugreek seed supplementation on milk yield and milk quality characteristics in dairy goats. The goats' milk yield was not affected by fenugreek seed supplementation, whereas an increased milk fat content and decreased serum cholesterol and triglyceride level were observed. Fenugreek seed supplementation increased the oleic acid, elaidic acid, and arachidonic acid concentrations and changed the volatile compounds found in milk.

Ewes' reproductive performance could be predicted using the data available early in their life. Ewe birth rank, dam birth rank, first litter size, and first lambing interval are significantly associated with ewe reproductive performance up to the fourth year of life. Precise prediction of ewe reproductive performance using the early predictors is impossible due to the low R² predicted. The value of the lower threshold of the 95 % prediction interval might be useful in making selection decisions.

This study aimed to evaluate the effect of concentrate-based feeding (CF) and artificial pasture-based grazing (APG) management systems on milk yield, fatty acid, nutritional indices, and milk physicochemical characteristics of Awassi ewes.

In this study, we found that miR-369-3p inhibits the proliferation and differentiation of Aohan fine-wool sheep (AFWS) preadipocytes. This study provides a theoretical basis for further exploration of the molecular mechanism of fat deposition in sheep and other livestock.

The demand for mutton is increasing yearly. Sheep were raised to 180 d of age, and production performance was measured and recorded at 20-d intervals from 80 to 180 d. The sheep were then slaughtered at 180 d of age. Blood, tissues, and other samples were collected for follow-up experimental research. Finally, we detected a mutation site in a specific segment of the ovine MAP3K5 gene, and this site can be used as a molecular genetic marker to improve sheep body size traits.

The addition of 1 mL kg⁻¹ pomegranate seed oil (PSO) to feeds improved performance. The addition of PSO had a positive effect on shelf life, and it increased punicic acid and conjugated linoleic acid (CLA) levels without reducing egg quality.

The team that prepared this article developed and patented electrical teat dipping (ETD) to prevent cow mastitis. ETD was developed by combining teat dipping application and an electrical field stimulation technique on teats. In this study, it was aimed to determine the effects of ETD on clinical mastitis incidence and bulk tank milk somatic cell counts on dairy farms. Based on our findings, we conclude that the effects of ETD on mastitis rates reduction are very positive.

The effect of STEAP4 (six-transmembrane epithelial antigen of the prostate 4) on goat adipocyte differentiation is unclear. We cloned the goat STEAP4 gene based on the Jianzhou Da’er goat and analyzed its properties and its expression in tissues and adipocytes; further, the positive effect on the expression of subcutaneous adipocytes was obvious. This study will provide a basis for elucidating the biological function of the STEAP4 gene in goat and provide a reference for goat molecular breeding.

We show that Staphylococcus aureus isolates obtained from cow milk at the stage of subclinical mastitis were resistant to antibiotics used to treat mastitis. The ability to form biofilms increases the opportunity for the spread of multidrug-resistant strains. S. aureus isolates carried resistance genes, most encoding resistance to β-lactams and tetracyclines. S. aureus in raw milk poses a potential risk of developing foodborne infections and spread of antibiotic resistance between species.

Piglet losses in pig farming remain a concern and need to be addressed through the implementation of new sustainable breeding and management strategies. Indeed, piglets are particularly vulnerable in the first days of life. This review provides an overview of the current knowledge on piglet responses during adaptation to life outside the uterus, which is particularly important for improving the vitality of newborn piglets and animal welfare in pig production in various farming systems.

This study aimed to investigate the relationship between increases in luteinizing hormone (LH) profiles induced by gonadotropin-releasing hormone (GnRH) in the serum and vaginal mucus of Japanese Black beef cows. A peak serum LH concentration was identified at 2.5 h post-GnRH administration, with serum concentrations returning to near-pre-GnRH-administration values after 6.5 h, whereas the peak LH concentration of vaginal mucus was identified 4.5 h after GnRH administration.

IPB-D1 chickens are the result of a cross between Indonesian local chickens and broilers. They have the potential to produce new female lines with egg production ranging from 50–60 %. The results found that the single-nucleotide polymorphism association analysis of egg production showed that the point mutation g.8052T > C had a significant effect on the egg production of IPB-D1 chickens, with potential for marker-assisted selection for the characteristics of egg production in IPB-D1 chickens.

Three-way crossbreeding was performed with Australian White, Dorper, and Charollais as terminal male parents and elite F1 hybrids of Australian × Han, Dorper × Han, and Charollais × Han as female parents. Based on the growth of three-way crossbred and Small-tailed Han lambs as well as the effects of CLPG, the offspring of male Australian White and female Charollais × Han showed apparent heterosis, and the individuals with the T allele had improved body weight and body size.

The morphometric and physical aspects of eight cattle breeds in Indonesia were examined. The morphometric differences might be attributable to environmental and breed factors. Physical characteristics are critical for cattle identification and body measurements. There were two distinct clusters of cattle breeds with a common ancestor. The most important factor in estimating body weight was the heart girth circumference. Ongole Grade cattle are determined to be potential beef cattle in Indonesia.

During pregnancy, iron requirements increase for optimal placental and fetal growth, the expansion of maternal red-cell mass, and to prevent complications related to maternal iron deficiency anemia. Red-cell parameters and iron status provide consistent additional information for the diagnosis of iron deficiency conditions. The aim of this work was to evaluate the serum iron status and its relation to hematological indexes in pregnant mares. Blood samples were taken from 31 Spanish Purebreds.

According to the discovered results, high diversity was recorded in the south. In addition, the results noticed a high degree of geographical distribution (east, west, middle, and south). Generally, the current study records a high internal-breeding factor, although the samples were collected randomly.

This paper reports on the genetic diversity parameters of 12 Beninese indigenous guinea fowl phenotypes distributed in three climatic zones. More information has been provided through the results on genetic conservation and adaptability of the phenotypes to the local environment under climate change's continuous impact.

There are few studies investigating the RNA-binding protein Lin28B and ovine puberty. This study focuses on understanding how its overexpression changes microRNA levels, cell proliferation, and estrogen secretion. To assess these changes, we used quantitative real-time (qRT) PCR, overexpression vectors, and ELISA. We found that Lin28B overexpression decreases let-7b and let-7g levels and increases granulosa cell proliferation and their estrogen secretion.

Phenotypic and genetic trends, genetic parameters, and breeding values of the fattening and slaughter traits of 1162 Hungarian Simmental bulls were evaluated for the progeny test database. Based on our results, it seems that the simultaneous selection, in which, in addition to milk production, meat production is included in the dual-production index at a proportion of one-third, causes neither a substantial improvement nor a deterioration in the meat production of the Hungarian Simmental breed.

The effect of adding propolis to high-energy feed for laying hens on performance values and ratio of liver fat was investigated. High-energy feed adversely affected egg production and liver fat ratio, but the addition of 100 or 200 mg kg^-1 of propolis improved egg production and decreased liver fat ratio.

This study is focused on the development of the inbreeding coefficients in Zwartbles sheep in the Czech Republic. The effect of inbreeding on meat yield was investigated. There was a statistically significant increase in inbreeding coefficient between 1997–2021. A statistically significant effect of the inbreeding coefficient on weight at 100 d, musculus longissimus dorsi (MLD) thickness, and back fat thickness was found. A negative relationship between inbreeding and meat yield was found.

The aims of this study were to estimate the genetic parameters of test day milk yield in the population of the White Maritza sheep breed and to choose the most appropriate linear models for genetic-parameter estimation of test day milk yield. Nine test day models were formulated and tested for the estimation of genetic parameters of milk yield. To compare the linear models described above, Akaike information criterion, Bayesian information criterion and log-likelihood were calculated.

The concentrations of the trace minerals iron, zinc, copper, and manganese in the empty-body and body tissue fractions of growing Fleckvieh (German Simmental) bulls slaughtered at 120–780 kg live weight were determined. Results were used to calculate trace mineral accretion rates in bulls from 100 to 800 kg live weight. Accretion rates changed during growth and were not affected by high-concentrate feeding. Provided data may be used to calculate net trace mineral requirements of growing bulls.
