Abstract In the present study, an herbal feed additive was tested for partial-to-complete replacement of synthetic methionine in poultry diets, along with its effects on performance, breast and thigh meat chemical composition, oxidative stability during refrigerated storage and the expression of five target genes in liver. In a 35 days trial, 600 one-day-old male chicks were randomly allocated to 4 groups with 10 replicates. Birds in the control group were fed a regular maize–soybean-based diet that covered DL-methionine needs while the second group (Meth40) was similar to control but contained only DL – Methionine at 40% of control diet. Diet in third group contained DLMethionine at 40% of control and the herbal feed additive Methiorep TMMeth40+Mrep) with extracts of Boerhavia diffusa, Azadirachta indica, Vigna mungo and Trigonella foenum-graecum. Diet of fourth group was formulated to totally replace DL Methionine by Methiorep TM (Mrep). Body weight gain and feed consumption were weekly recorded. At the end of the trial, all birds were slaughtered and 2 chickens per pen were selected for meat and liver sampling. The liver was tested for the expression of five target genes, namely Methionine synthase (MTR), Tyrosine aminotransferase (TAT), Spermidine synthase (SMS), Methionine sulfoxide reductase (MSRB1) and Betaine homocysteine S-methyltransferase (BHMT). The results showed that the Meth40 group had reduced body weight compared to the Meth40+Mrep group while the Control and Mrep groups had comparable weights. Feed intake and feed conversion ratio did not differ among the experimental groups. Carcass, breast and thigh meat yield were higher in the Mrep and the Control compared to Meth40 and Meth40+Mrep groups. Also, meat oxidation was significantly lower in herbal groups compared to the control group. After normalization to β-actin expression, quantitative real-time PCR analysis revealed an induction in the expression of MTR and SMS genes in the liver of both herbal treated groups. No changes were observed for the TAT, MSRB1and BHMT genes in the herbal treated groups compared to the control or the Meth40 group. In conclusion, herbal feed additives with specific plant extracts may be able to improve both growth performance and antioxidant activity of broiler chickens, phenolic content; yet, they may also support in amino acid efficient use of broiler.

Abstract This study was conducted to test the hypothesis that a new rye hybrid produced in Romania (Suceveana variety) could not impair the performance and meat quality of broiler chickens. A total of 360-day-old male Ross 308 broiler chicks (40.1±2.3 g) were randomly assigned to 3 dietary treatments replicated 6 times having 20 birds per replicate. Experimental diets were formulated to replace 25 and 50% of corn with rye (RYE 25 and RYE 50, respectively) as energy-yielding sources, whereas the control diet (CON) was 100% corn-based. All diets were formulated to be isocaloric and isonitrogenous, with similar total lysine and total sulfur amino acids. The results indicated similar outcomes of the local rye hybrid to commonly used corn-containing diets in terms of performance and carcasses. There were no differences in fundamental physicochemical (i.e., pH, protein, fat, moisture) or textural attributes of breast muscles due to dietary treatment, as well. However, the substitution of corn with rye reduced (P = 0.008) abdominal fat associated with an increase in CIE color (P< 0.001). Thus, the Suceveana rye hybrid can be included in broiler diets, from hatching to day 42, without any adverse effects on the bird’s performance.

Abstract Agro-industrial by-products can play an important role in the animal feeding, being an alternative to conventional raw materials. These two wastes can be considered as important sources of bioactive compounds that can be used in animal feed with multiple benefits for animal health. This study has investigated the anti-inflammatory and anti-oxidant in vitro capacity of grape seed and sea buckthorn meals, as waste resulted from the oil industry in order to be used in swine nutrition. The in vitro study was realised on swine peripheral blood mononuclear cells challenged with LPS and treated or not with grape seed meal and sea buckthorn meal extracts. Our results show that both extracts have the capacity to attenuate the inflammation and oxidative stress induced by LPS. The effect induced by the grape seed meal extract was in majority of cases more important than of the sea buckthorn, this effect might be due to a different composition in bioactive compounds (polyphenols, PUFA etc) of the two extracts.

Abstract Semen quality and fertility in crossbreeding between white plumage and black plumage indigenous turkey hens using artificial insemination were investigated. Eighty-two healthy indigenous turkeys, comprising 72 hens (Thirty-two black and forty white) and 10 toms (five black and five white) were used. The turkeys were grouped into four treatments based on the breeding plans: T1 (White toms X White hens), T2 (Black toms X Black hens), T3 (White toms X black hens) and T4 (Black toms X White hens). Semen was harvested from white toms, pooled, and inseminated at 0.02ml into hens in T1 and T3. Semen harvested from black toms were also pooled and inseminated at same dose into hens in T2 and T4. White tom semen quality parameters were 97%, 91%, 96%, and 532×106 cells/mL for mass activity, motility, livability, and sperm concentration, respectively. Black tom semen quality parameters were 91%, 93%, 95%, and 293×106 cells/mL for mass activity, motility, livability, and sperm concentration, respectively. Egg fertility were 99.63% in T1, 99.81% (T2), 99.84%(T3), and 99.27% (T4). Hatchability in T1, T2, T3, and T4 were 57.67%, 72.54%, 67.65%, and 64.82%, respectively. Besides sperm concentration, semen quality parameters and fertility in indigenous turkey were not affected by plumage colour

Abstract This study aimed to evaluate the effects of natural tannins in laying hens’ diets on production parameters and the alterations of eggs’ physical properties during storage time and temperature. A six weeks experiment was carried out on 168 Lohmann Brown laying hens, 51 weeks of age, accommodated within digestibility cages, structured on 3 levels. The dietary basic structure was the same for all 3 tested groups. The difference between the experimental and control groups was established by the type of plant additive added E1 (0.5% chestnut flour) vs. E2 (0.5% bark oak). At the end of the experiment, 36 eggs/group were collected to evaluate internal and external quality parameters of eggs during storage. These eggs were divided into two parts: 18 eggs/group were kept at room temperature (22°C) and 18 eggs/group were kept in the refrigerator (4°C) for 42 days and analysed to determine shelf time. The results obtained showed that the physical parameters of eggs laid by hens fed with diets supplemented with natural source of tannins (chestnut powder and oak bark) were improved in terms of Haugh Units, yolk colour and eggshell thickness, but only in refrigeration storage conditions.

Abstract The aim of the study was to develop a dual-purpose cross suitable for rearing in alternative systems and to examine its growth performance and carcass composition in comparison to the parent lines. The experiment was carried out in the experimental poultry farm in the Institute of Animal Science - Kostinbrod. The cross was developed using females of a layer type line L and cocks from line BB. The latter was based on Bresse Gauloise that is also dual purpose but mainly used for meat. The chickens from the lines and the cross were reared in mixed-sex groups on deep litter, at stocking density of 25 birds/m2, and fed with standard broiler feed until the age of 9 weeks. Then the males were separated and sent to slaughter while the females were left for layers. Crossing hens from layer type line L with BB cocks resulted in dual-purpose chickens with a live weight and feed efficiency that were better in comparison to L line, but lower when compared to the BB line. These parameters were however, lower than the typically observed in this type of poultry. Nevertheless, the chickens displayed good carcass composition and deposited low content of abdominal fat, thus revealing good potential to be successfully realized in market.

Abstract The study evaluated the effect of Vernonia amygdalina leaf meal on semen indices, serum testosterone and sperm reserve of male rabbits. Forty rabbit bucks were randomly assigned into four groups and fed the experimental diets containing Vernonia amygdalina (VLM) at 0, 5, 10 and 15 % levels for 84days. Reproductive indices were evaluated using standard procedures. Data obtained were subjected to analysis of variance at p<0.05. All semen in rabbits fed 0, 5 and 10 % VLM had milky colour while 14.8% light green and 85.2% milky semen colour was observed in bucks fed 15%VLM. Libido score reduced in rabbits fed VLM diets. Bucks fed 15%VLM had significantly higher semen volume (0.47ml). VLM had no significant effect on spermatozoa mass motility, progressive motility and sperm concentration. Live sperm cells significantly increased in bucks fed 5 and 10% VLM diets. VLM had significant (p<0.05) effect on spermatozoa morphology. Vernonia amygdalina leaf meal had no significant (p<0.05) impact on testosterone, testicular and epididymal indices. In conclusion, up to 10%VLM can be adopted as feed ingredient for male rabbit breeder stock without deleterious effect on reproductive indices.

Abstract The article focuses on the chemical composition, nutritional value and the effects of four minor oilseeds’ cakes when used in ruminants’ nutrition. Although less abundant than the well-known major oilseeds, mechanical extraction of oils from the minor oilseeds retrieves important quantities of cakes which, beside a high content of crude protein have variable, yet important proportions of residual fat, upon the efficiency of the extraction processes and retains some nutritional properties of the seeds, including the content in bioactive substances. The browse of the literature on minor oilseeds cakes retrieved scattered and contradictory data, implying a need for systematic comparison, among them and against a reference feed. Although specific literature is scarce, a number of articles reported the chemical composition of the four cakes, allowing their hierarchization and their comparison with the rapeseed cake, considered as reference feed. On the other hand, the review identified numerous knowledge gaps, concerning the effects of the four cakes on rumen metabolism and their effects on animals’ productive performances. However, the literature review confirmed that the four cakes can be good substitutes of rapeseed cakes or similar feeds in ruminants’ nutrition, as long as the potential effects of bioactive substances taken into consideration.

Abstract Haemo-thermoregulatory response of twenty-six adult geese comprising of 12 males and 14 females randomly allotted to four groups (Wallowed males, non-wallowed males, wallowed females and non-wallowed females) in a completely randomized design for seven weeks was evaluated. Wallowing was done every alternate day. Respiratory rate (RR), rectal temperature (RT) and pulse rate (PUR) were recorded. On days 1 and 49, blood samples (3mL/geese) were collected from geese in each group and analysed for haematological parameters using standard procedures. There was no sex effect on the RR and PUR but significantly (p<0.05) higher RT was observed in males (40.69°C) compared to females (40.53°C). The RR, RT and PUR were not significantly affected by wallowing. Interactions effect between sex and wallowing on RR, RT and PUR was not significant. Only platelet counts were significantly higher in females (17.70) than males (14.68). Wallowed Geese had significantly lower packed cell volume (37.46±5.13%), haemoglobin (11.85±1.69g/dl) and monocytes (2.81±0.63%) than other treatments. Wallowed Female geese had significantly lower haemoglobin (10.93g/dL) and monocytes (2.86%) compared to those without wallow treatment. Therefore, wallowing has mild influence on the thermoregulatory and haematological indices of geese reared under low temperature-humidity index during non-breeding season.

Abstract The focus of this research was to investigate how tannin extract from black tea influenced the hematological and histopathological evaluations of male rabbits fed a mycotoxin-contaminated feed, including 17 ppb aflatoxin, 5 ppb ochratoxin and 2 ppb fumonisin. A total of 28 local male rabbits were allocated into four groups, the first of which was a control group. The second was fed a Mycotoxin-contaminated meal. The third was given a Mycotoxin feeding with tannin extracts (125mg/mL per head) administered orally, while the fourth was fed a Mycotoxin contaminated diet with tannin extracts (250 mg/mL per head) given orally. The findings revealed that tannin extracts seemed to have a significant positive impact on haematological results, particularly RBCs and WBCs, throughout the period; however, the 250 mg/mL dose showed no significant differences in Hb levels. Nonetheless, as compared to the Mycotoxin group, the histopathological sections of tannin extract demonstrated a reduction in the toxicity of the Mycotoxin diet on the liver and kidney tissues; conversely, the tissue sections of the control animals showed no abnormalities. In male rabbits fed contaminated Mycotoxin diets, tannin extract from black tea was found to have a favourable impact on hematological activities and vital organs such as the liver and kidney.
