The aim of this study was to assess the performance and meat quality of meat-type guinea fowl fed commercial diets under two different feeding programs similar to those for turkeys and broilers. Findings of the study suggest that these diets can be used in meat-type guinea fowl rearing without affecting the productive traits and meat quality. However, due to the lower price of chicken feed (due to lower protein content), its use seems to be more justified from an economic point of view.

As part of the development of a breeding programme for dairy goats to support sustainable production, we aimed to identify selection traits measured in regular milk recording. In summary, the length of the animal's productive life, lifetime efficiency, and the milk yield efficiency with respect the total number of lactating days are suitable traits to indicate lifetime productivity in dairy goats. Breeding associations must now decide which traits to implement in the breeding programme.

Tibetan pigs are well adapted to high-altitude environments with a set of physiological features for more efficient blood flow for oxygen delivery under hypobaric hypoxia. We established the anatomy, physiology and molecular characteristics of the lung adaptive intelligence. Our finding suggest that the lung genetic mechanism of hypoxic adaptation in Tibetan pigs is valuable to understand.

The regulation of glycolysis and heat shock proteins (HSPs) in Gannan yaks at different altitudes were determined. We found that HIF1A and PDK4 expression and glycolysis-related enzyme level were significantly increased, but CA level was significantly decreased with altitude. HSP27 and HSP60 were highly expressed with altitude. These results are useful to better understand the unique adaptability of Gannan yaks, allowing them to survive in hypoxia conditions.

In this study, the meat quality traits and fatty acid composition of Hair Goat and Saanen × Hair Goat (G₁) crossbred kids fattened under intensive, semi-intensive and extensive conditions were determined. The conjugate linoleic acid contents of Hair Goat kids were respectively measured as 0.48 %, 0.55 % and 0.65 %. The conjugate linoleic acid contents of Saanen × Hair Goat (G₁) kids were respectively measured as 0.52 %, 0.58 % and 0.73 %.

Stocking broilers at a high density has been a strategy to optimize the area of the cage. If the environment and rearing management are not properly managed, stocking broilers at a high density may, however, result in stressful conditions that are harmful for the production and health of broilers. To ameliorate these unfavourable effects of overcrowding stress, dietary interventions using probiotics, prebiotics, synbiotics, herbs, vitamins, etc. have been conducted.

In this work, we analyzed the effects of trehalose on sheep EEC proliferation and possible mechanisms affecting its role. Our study suggested that exogenous trehalose exhibits antioxidant activity through increasing the activities of CAT, GSH-Px, and the expression level of GPX5. The cell line cultured provides a strong resource for elucidating the transcriptional networks that coordinate functions of sheep epididymis epithelium and have greatly enhanced our understanding of epididymis biology.

Insulin-like growth factor 1 (IGF1) is one of the important endocrine hormones that plays a role in regulating growth and development of animals. In this study, we found two single nucleotide polymorphisms (SNPs) in the exon3 region of IGF1 in the Shitou goose. IGF1 mRNA was extensively expressed in various tissues, with high abundant expression in the liver, breast muscle and leg muscle at three growth stages. This provides a foundation for regulatory mechanisms of IGF1 in geese.

This study aimed to detect a potential association between GHR/AluI polymorphism and milk yield and milk composition traits in dairy cows raised in commercial herds using the PCR-RFLP assay. In conclusion, the GHR gene should be regarded as potential candidate genes in marker-assisted selection programs to improve the performance of milk and related traits in Turkey dairy cattle populations.

DGAT1 and Lep genes are closely related to reproduction, growth, milk yield in water buffalo breeds. This study aimed to identify genetic variation in the DGAT1 and Lep gene regions in 150 water buffalo individuals in Turkey. A total of 38 nucleotide variations and indels have identified the Lep gene, and two mutations were defined in the point of 155 and 275 nucleotide that is three genotypes for S allele and Y allele of DGAT1 gene in intron 7 in Anatolian water buffalo populations.

Packaging methods (vacuum packaging and modified atmosphere packaging) allow for maintaining high-quality meat during a long period of storage (30 d) under refrigeration conditions. An interaction between the storage time, packaging method, and mesophilic aerobic bacteria and coliform counts was observed. Storage time affected the number of aerobic psychrotrophic bacteria, redness, pH, shear force value, and desirability of the meat's aroma and taste.

Goats are produced in extensive systems with low productive yields. Therefore, intensive systems improve productivity; however, in this system, diet is the most costly parameter. The cottonseed cake has the necessary nutritional characteristics to be able to substitute traditional ingredients (such as soybean meal) and to reduce the diet cost. Thus, it is necessary to determine the best level of inclusion of cottonseed cake in feedlot goats' diets to improve meat production and quality.

After performing in-depth research on miRNA localization, distribution, and function-related metabolism, we found that these exosome-concentrated miRNA target genes were interrelated with development and basic cell functions, such as metabolism and immunity. It is speculated that miRNAs in milk can influence offspring via milk exosomes.

Here we clarify the specific expression and mechanism of the EPH receptor and Ephrin during the development of hair follicles, as well as their upstream and downstream signaling pathways and activation pathways. This study verified the effect of EPHA4 and Ephrin A3 genes on fine-hair follicles through RT-qPCR and immunohistochemistry testing. It is of great significance as it could speed up the promotion of breeding sheep for wool.

The study aimed to highlight the general trend of indigenous Lao pig utilization and the altered reproductive performance with special reference to location and rearing systems. Indigenous pigs are not only important for household consumption, but they also serve as household savings that the households use anytime, i.e. to support their children's education and traditional activity performance. Proper management is needed to improve reproductive performance of indigenous pigs in Laos.

The interaction between genotype and environment changes depending on the interaction of the sub-environments. The environments have a hierarchically structured impact. With regard to the growth of the chicks, nutrition seems to have a higher value than red mite infestation. While a clear interaction between genotypes and poultry red mite infestation was observed in ad libitum feeding, the genotypes reacted similarly to infestation under feed restrictions.

The use of cull ewes has been an adopted practice to increase the profitability of the activity. The production of the ewes can be maximized with the adoption of feedlotting. However, feed is known to be the costliest factor in animal production. In this context, by-products such as cottonseed emerged as an alternative to replace the most commonly used ingredients without affecting animal productivity. Calcium lignosulfonate is a by-product that can be used to improve ruminal digestion.

This study investigated the interactive effects of weather conditions, transportation time and loading density on carcass damages and meat quality traits of pigs. Pigs exposed to short transportation at low space allocation during hot weather conditions produced the lowest pork quality. Pigs exposed to short transportation at high loading density during cold weather conditions produced the highest pork quality. Hence, weather and transport conditions are of great importance for the pork quality.

In this study, we found that 21 mutation loci and 3 haplotypes were significantly associated with litter size in Nubian goat. This would allow breeders to take more precise selection decisions, leading to significantly higher productivity and profitability within the Nubian goat.

The objective of this study was to evaluate the intake, digestibility, nitrogen balance, and performance of feedlot lambs fed diets containing crude glycerin. Although it did not affect the intake and digestibility of most nutrients, the inclusion of 100 and 200 g kg^-1 DM of crude glycerin in lambs' diets tended to worsen performance, indicating that the ideal level of inclusion should be below 100 g kg^-1 DM of crude glycerin.

Our results suggest that estrous cycles may be associated with clock gene expression in the Small-tailed Han sheep (STH sheep). This is the first study to systematically analyze the expression patterns of clock genes of different estrous cycles in ewes, which could form a basis for further studies to develop the relationship between clock genes and the estrous cycle.

The AS-PCR analyzes genotypes using two pairs of primer in basic equipment: a thermal cycler and an electrophoresis system. This research team analyzed three SNPs in 10 Korean cattle using the AS-PCR method. The result can be easily confirmed visually through the appearance of different amplification sizes depending on allele. Therefore, the use of the AS-PCR method will enable researchers to carry out genotyping analysis for SNPs without the use of sophisticated instrumentation and at low cost.

This research was conducted to valorize crude olive cake, extracted olive cake, and olive leaves using an exogenous fibrolytic enzyme in ruminal nutrition. This additive improved only the nutritional value of crude olive cake and olive leaves. These results can encourage breeders to use this waste as feed at a low cost in animal nutrition. This valorization of waste is a good solution to reduce pollution.

Cashmere is a natural fiber from cashmere goats. The textile has been favored by consumers due to typical features like lightness, softness, and comfort. In this study, we show that circRNA-0100 promotes the differentiation of secondary hair follicle stem cells into hair lineage via sequestering miR-153-3p to heighten the KLF5 expression. Our results provide significant information for artificially regulating the secondary hair follicle regeneration and cashmere growth in cashmere goats.

The aim of the study was to evaluate Virginia fanpetals silage based on an apparent digestibility and palatability test using sheep. Alfalfa silage was used as standard forage. Virginia fanpetals silage has a chemical composition similar to that of alfalfa, but it was characterized by a more desirable fermentation pattern and higher digestibility and was more willingly consumed by sheep.

Dystocia in swine is a risky condition that causes stress and pain to sows and piglets. This study investigated factors affecting dystocia in induced farrowings, thereby providing more knowledge into this underestimated issue. Results showed that dystocia is common in swine; relative birth order, birth weight, and stillbirth were the most significant risk factors for dystocia. These data suggested that last one-third of farrowing process is most important stage to be supervised.

In this study, we first studied the expression of ZNF33B in bovine ovaries and early embryos, and we determined the expression position and quantity of ZNF33B in ovaries and the temporal and spatial specificity of ZNF33B expression in early embryos. Secondly, the G-61G>T mutation of 5' UTR in ZNF33B gene was studied. The frequency of the G genotype was 0.3489 and that of the T genotype was 0.6511. This mutation was significantly correlated with the superovulation traits in cattle.

Oak acorn diets fed to lambs during the pre-weaning period did not negatively affect their future growth performance. Replacing barley grain with oak acorn in concentrate during the post-weaning period had no effects on a lamb’s growth performance, health and viability. Oak acorn can replace up to 40 % of barley grain in finishing feedlot lamb diets. The substitution of oak acorn for barley has no effects on carcass traits.

Tissue inhibitor of metalloproteinase 1 (TIMP1) plays a crucial role in follicle growth and embryonic development. Ovarian granulosa cells also play an essential role in these processes. However, the effect of TIMP1 on the biological function of goat ovarian granulosa cells remains unknown. The objective of this study was to explore the impact of TIMP1 on granulosa cell proliferation and reproductive characteristics in goats.

This study was conducted to estimate the (co)variance components for birth and weaning weight (BW and WW) in Awassi sheep. Estimates were calculated from single-trait analysis by AI-REML method, by fitting six different univariate animal models. LogL, AIC, BIC, and the goodness of fit between the two models were compared with the LRT. Model 3 for BW and Model 2 for WW were the best models by LogL; Models 2–4 for BW and Models 2–6 for WW were significant by the LRT ratio test.

This study evaluated the impact of a feed additive containing Scutellaria baicalensis extract on beef cattle health status and performance. A total of 143 male Charolaise cattle were assigned to a control or supplemented group, and health status and growth performance was monitored over 4 months. Our results revealed that long-term dietary inclusion of S. baicalensis did not impair animals’ health status and performance, indicating no detrimental effect of the feed additive.

This study's aim is to investigate the polymorphism of Simmental cattle raised on a private farm in terms of the CSN3 gene locus from milk proteins by using the PCR-RFLP method and to reveal the distribution of genotype and allele frequencies of animals in terms of related gene locations. In addition, the relationship between genotypes and some performance characteristics is investigated.

Our research tried new ideas and measured the milk production performance of cashmere goats and found that the nutritional indicators of milk of Liaoning cashmere goats were excellent, laying a theoretical foundation for the future development of breeding to cashmere goats. At the same time, it also provides theoretical support for producers and can screen individual genotypes based on the experimental results during seed selection, thereby improving production performance to a certain extent.

Phytogenics emerged as a substitute of in-feed antibiotics following the ban on their use at subtherapeutic levels in poultry diets. However, the effects of phytogenics have been uncertain in studies conducted so far. Combined use of phytogenics and probiotics may be effective in this regard. In a nutshell, this study shows that combined use of phytogenics and Bacillus licheniformis possess the potential to improve oxidative stability of breast meat and immune response of broiler chickens.

This study aimed to determine the changes in the performance, welfare, and productivity level of broiler chickens reared at various group sizes under intensive field conditions. Rearing in groups of 6000 broilers had better performance and higher overall productivity than others, but they tended to show more serious body defects, while a group size of 3000 broilers was more favorable in terms of welfare.

Our findings provide valuable genetic markers for litter size in sheep.

Circulating 17-β-estradiol (E₂), progesterone (P₄), and cortisol concentrations of 30 non-pregnant, pregnant, and lactating Nicastrese goats carrying single or twin fetuses were evaluated. E₂ and P₄ were higher during pregnancy and lower in non-pregnancy. In mothers with twins, P₄ was higher in mid-gestation and E₂ lower at >50–70 d of lactation. Different physiological conditions induced a temporal relationship with the endocrine profile in Nicastrese goats.

How actual industrial stocking densities generally affect the slaughter performance and meat quality parameters of hybrid Pekin ducks reared under industrial conditions was examined in this experiment. With the findings of the research it can be concluded that, when actually applied stocking densities rearing hybrid Pekin ducks increase, some slaughter parameters and few meat quality parameters are negatively affected.

We studied the impact of the COVID-19 restrictive measures on the extensive farming system of small ruminants. We found that the breeders’ daily work routine was negatively affected in holdings with a high number of sheep. The majority of breeders did not change the movements of the animals in pastures, the amount of the given feedstuffs, the hygienic conditions on the farms, or the employed workers. A decrease in demand for animal products and a decrease in their prices were observed.

Important advances have been found in genetic improvement of local goats around the world; however, important limitations are still observed in basic aspects of nutrition, health, and genetics, among others.

The need to reduce the environmental impact from zootechnic productions and to avoid the exploitation of land resources is a current issue. For this reason, the study investigated the replacement of corn silage with triticale silage in the diet of mid-lactation dairy cows by evaluating blood and productive parameters. Diet did not affect blood and milk parameters, suggesting the feasibility of the replacement of corn silage by triticale silage in the diet of mid-lactation dairy cows.
