The effect of exogenous melatonin (EM) on growth, physiological and haematological parameters of West African dwarf (WAD) bucks was evaluated in the experiment. Intact selected sixteen WAD bucks were distributed into 4 treatment groups of 0, 3, 6 and 9 mg EM. Bucks were orally dozed with EM 3 times per week for 16 weeks. Blood samples were collected at 0th week, 8th week and 16th week of experiment for evaluation of haematological parameters. Analysis of Variance was carried out and significant means were separated using SAS. Results showed bucks given 6 mg EM had higher average daily weight gain of 31.3 g compared with others. Feed and water intake were similar across treatments, but feed conversion ratio was significantly lower in bucks given 6 mg EM. Values recorded in the morning of data collection days showed pulse and respiratory rates to be significantly different, with bucks given 6 mg of EM having lowest values. 6 mg group was also different for packed cell volume (32.57%), haemoglobin (10.72g/dl), red blood cell (11.38 1012 /L), neutrophil (35.50%) and lymphocyte (64.30%). Therefore, dose of 6 mg/animal EM influences growth performance, physiological and haematological parameters of WAD bucks positively and is therefore recommended for WAD bucks for optimal performance.

Lactoferrin is a member of the high affinity to glycoprotein family of transferrin for iron and plays a role in natural immunity as well as antibacterial, antifungal, antiviral, antiparasitic, antioxidant, anticancer, antiinflammatory, bone health and immunomodulation. The aim this study was to investigate of the acute effect of lactoferrin on paraoxonase activity, oxidant/antioxidant system and total protein, albumin and globulin. This study was carried out on 6-month Sprague Dawley rats in a total number of 20 subjects. Paraoxonase activity, total antioxidant capacity (TAC), total oxidant capacity (TOC), total protein, albumin and globulin levels were measured through the spectrophotometer. When the lactoferrin group was compared with the control group, it was found that TAC levels were statistically higher (P<0.05), TOC levels were statistically lower (P<0.01) and paraoxonase activity was statistically higher (P<0.05). There was no difference in total protein and globulin levels in the lactoferrin group compared to the control group. As a result, acute lactoferrin administration may play an important role in the regulation of antioxidant balance by increasing paraoxonase activity and decreasing the level of reactive oxygen species.

Haemoparasite constitute a major challenge in native chicken production in Africa. This study determines the genetic diversity and the effect of TLR2B gene polymorphism on haemoparasite and haematology of the chickens based on genotype and sex. 600 chickens of 25 weeks old consisting of Naked neck (NN), Normal feather (NF), and the Frizzle feather (FF) reared in battery cage-system were sampled for blood and analyzed for haematology, parasite occurrence and load, polymerase chain reaction, and gene sequencing. Polymorphisms were detected and their effect on haematology was determined. Results showed the occurrence of Plasmodium gallinacieum, Trypanosoma brucei, and Leucocytozoon schoutedeni with NF having the highest occurrence followed by NN and FF chicken genotype. There was a significant (P <0.05) effect of genotype and sex on haematology. Seven of the eight polymorphism detected were singleton and found only in NF while parsimonious 656GA was detected in all the chicken genotypes with no relationship with haematology and haemoparasite. NF had the highest nucleotide (0.00114) and haplotype diversity (0.584). The study revealed the occurrence of genetic variation in TLR2B gene, haematology, and haemoparasite in FUNAAB Alpha chickens which could provide baseline information in future breeding programmes of the chicken for the tropical environment.

Extracts of seaweeds are promising candidates for eco-friendly, safe, and biodegradable larvicides and as alternatives to chemical larvicides used in mosquito control strategies. This study evaluated the larvicidal effects of Dictyota ciliolata on the mosquito larvae of Aedes aegypti, Anopheles gambiae, and Culex quinquefasciatus. The seaweed was extracted using ethanol and methanol. The larvicidal assays were conducted per WHO standards by exposing twenty 4th instar larvae to 100, 200, 300, 400, 500, and 600 mg/L of the derived extracts. The LC50 and LC95 values were obtained by calculating the probit values of the observed mortalities. LC50 of the ethanolic and methanolic extracts of Dictyota ciliolata against Anopheles gambiae larvae were 238.45 mg/L and 497.28 mg/L respectively; 179.02 mg/L and 224.96 mg/L respectively against Aedes aegypti, and 167.49 mg/L and 226.69 mg/L respectively for Culex quinquefasciatus. The results established that ethanolic and methanolic seaweed extracts were most influential on Culex quinquefasciatus followed by Aedes aegypti and Anopheles gambiae. Although mortalities were recorded for Poecilia reticulata, such may not be enough to de-emphasize the observed larvicidal potentials of Dictyota ciliolata as some other factors could have been responsible for the said mortalities in the non-target species.

The Romanian Carcass Classification Commission (RCCC) was established in 2004 and it became the official partner for delivering carcass quality information to the European Commission in 2007. RCCC is the NGO serving the interests of the private stakeholders in the meat chain (farmers, slaughterhouses, processors, and traders), which guarantees the neutrality and objectivity of carcass quality assessment according to SEUROP grading system’s legally binding rules. Considering the importance of an independent assessment of the slaughter pig quality for the entire food chain, the analysis of the carcass quality evolution in Romania is important for future benchmarking and trend assessments as well. The current review is based on the public data developed in time by the RCCC. It demonstrates the importance of a professional organization measuring the quality of carcass in slaughtered pigs and its impact on the meat chain as a whole, both for its stakeholders and consumers. It also highlights the evolution of the pig carcasses produced in Romania, underlining the main factors involved and expected trends under the current circumstances of the presence and spread of the African Swine Fever virus (ASF) within Romania in the last four years. The main conclusion is that while the carcass quality improved over time, the graded carcass number decreased after 2017, primarily due to ASF outbreaks in commercial farms and the overall reduction of the farmed pig inventory, and increasing dependence of Romanian consumers on imports.

This study aims to characterize the sheep population phenotypically in three zones in northeastern Algeria: Aures, Hodna and Ziban. A total of 160 female animals of 2 to 4 years of age were subject to 4 quantitative linear body measurements (body length BL, withers height WH, tail length TL and wool weight WW) and 9 qualitative physical traits (head length HL, ear orientation EO, horn presence H, neck length NL, wool extent WE, tail texture TT, eyes shape ES, head color HC and wool color WC). The results indicate that the sheep population in these areas belonged to the Ouled Djellel sheep breed with some abnormal phenotypes, which refers to uncontrolled crossbreeding. Body measurements show moderate variation coefficient values, with the highest value reported for WW (7.37%). However, despite the weak correlations found in this study, clear ones were revealed between WH and TL (0.30) and BL and WW (0.26). The Hierarchical Agglomerative Clustering analysis sub-divided the sheep population into three classes, in which an overlap, according to body measurements, was remarked between Hodna and Ziban and between Aures and Ziban but not between Aures and Hodna.

The research was carried out in broiler houses coming from a commercial broiler farm. Two consecutive series of broiler were followed for each of the specific housing conditions in terms of bedding quality: straw: series 1 and 2 in shelter H4 and bedding mixture: ¼ straw and the rest sawdust for series 1 and 2 housed in shelter H10. The microclimate parameters were monitored daily in three different areas, the value of the three readings representing the average. To reduce the pH of the bedding and inclusive of the removal of ammonia resulting from the degradation of organic matter in the bedding, it is returned 2-3 times a week. The results reveal that: there are no exceedances of the values in terms of physical parameters of microclimate, between them there are extremely significant correlations (positive or negative). The correlation between the temperature of the straw bedding and the carbon dioxide in the shelter air is extremely significant and insignificant at the level of the mixed bedding. The pH of the bedding has lower values in the case of the straw ¼+ sawdust mixture by turning the bedding 2-3 times a week. The temperature value at the bedding level is lower in the case of straw compared to the mixture of straw ¼+ sawdust (29.69±2.38 0C - 26.35±2.64 0C), which entails significant differences (*P<0.05). Between the quality of the bedding in terms of pH and the amount of ammonia monitored at the level of the houses, there is an extremely close negative relationship: (-0.83*** ppm NH3), straw bedding and (-0.96*** ppm NH3) straw ¼+ sawdust mixture bedding. Conclusion: keeping the microclimate parameters under control by ensuring the necessary air volume, monitoring the pollutants but also the physical microclimate parameters, regular return of bedding have as a result low mortality rate and low percentage of ammonia burns which denotes ensuring good welfare conditions.

Farm profitability is heavily influenced by reproductive capacity. Fertility, prolificacy, and fecundity are all indicators of reproductive efficiency. In sheep with high economic value, prolificacy is a key reproduction parameter (Notter, 2008). Because most sheep breeds are monotocous, similar to Mouflon wild sheep (Garel et al., 2005), improving fecundity is a serious concern (Tang et al., 2019). This review aims to study genes and the genetic means of improving sheep reproduction parameters. Numerous mutations in the transforming growth factor (TGF) superfamily have been reported to influence sheep reproductive parameters. As a result, molecular genetics and marker-assisted selection (MAS) are essential in improving reproduction efficiency. If these mutations are not present in the population, introgression of the beneficial mutations to indigenous breeds is possible. Because within-breed selection has been considered relatively inefficient, due to the low heritability of the trait, crossbreeding of native breeds with prolific breeds has been the major means of genetically improving prolificacy. Studying fecundity genes is important in order to increase production efficiency and stabilizing optimal litter sizes. Different studies based on whole-genome sequencing (WGS), which are called genome-wide association studies (GWAS), and also proteomic studies, transcriptome analysis, and mitochondrial DNA analysis have revealed further genetic variation with medium or minor effects on reproduction.

Different studies based on whole-genome sequencing (WGS), which are called genome-wide association studies (GWAS), and also proteomic studies, transcriptome analysis, and mitochondrial DNA analysis have revealed further genetic variation with medium or minor effects on reproduction.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

The constant and accelerated increase of world fish production through the expansion of fisheries and the development of aquaculture has also generated a higher interest in animal welfare. In the present, is proven that the fish welfare is a factor that influences the quality of the product and the practices of capture and slaughter, which can compromise these attributes. The harvesting and suppressing life methods give to the biochemical processes of fish meat some particularities, as a result of the stressor to which it is subjected by tracking, agglomeration, space restriction and asphyxiation. In the view of all, it is important to correctly identify procedures that improve both the welfare of the fish and the quality of the product. In this review, there are highlighted some of the stunning and slaughter methods of fish used in the aquaculture or capture fisheries, focusing on the human agreed standards and international organizations. There are recommendations in this sense for operations prior to slaughter and the possibility of developing and implementing new methods, by country and species of fish. In this sense, the brain puncture stands out as a more humane method of slaughtering fish, which also improves the quality of the product.

Contamination of aquatic systems with pesticides occurs frequently. This study aimed to detect the levels of some pesticides: organochlorines, organophosphorus, pyrethroids, and carbamates groups in imported frozen and local fresh fish in Jordan. A total of 218 samples were randomly collected (194 imported frozen fish). Samples were analyzed using Liquid Chromatography with Tandem Mass Spectrometry (LC/Ms/Ms). Results showed that 23 different pesticides were found in this study. All 218 fish samples were contaminated with at least 4 compounds and maximally 12 pesticides. In terms of contamination rate, no significant differences between local and imported types were observed. Up to 65.2% of pesticides were detected at concentration higher than the maximum residue limit set by the WHO (10 ppb) in 215 samples (98.6%). These samples concluded heavy contaminations with different pesticides for either imported or locally raised products. Therefore, routine monitoring of pesticides in fish and their environment are officially required.
