Probiotic effects on growth performance, carcass traits, blood parameters, cecal microbiota, and immune response of broilers were studied. Two hundred one-day-old male chickens were allocated to one of five treatments (four replicates of 10 birds per treatment): control, and the same control diet supplemented with 0.005%, 0.01%, 0.015% and 0.02% probiotics. Probiotics in feed at 0.01% or higher levels of supplementation improved body weight gain (+12%) and feed conversion rate (-5%) compared with the control. There were no effects on carcass traits, but the relative weights of drumsticks and wings showed increasing and decreasing linear responses, respectively, to probiotic supplementation level. Blood plasma glucose and albumin contents linearly increased (from 167.1 to 200.5 mg dl-1, and from 1.70 to 3.25 g dl-1) with increasing probiotic supplementation. Triglycerides and cholesterol contents were lower in probiotic supplemented treatments (average contents 71.3 and 125.3 mg dl-1 vs. 92.6 and 149.9 mg dl-1 in the control). Probiotics decreased cecal Escherichia coli counts, but had no effects on immunity related organs or immune response. The linear trends, either positive or negative, observed in many of the parameters studied, suggest that more studies are needed to establish the optimal concentration of probiotics in broiler feed.

Sixty 7-week-old New Zealand White rabbits were randomly distributed into 5 equal experimental groups. The experimental rabbits were fed the tested diets till 14 weeks of age during summer season. The basal diet without feed additives (control; T1) and the other experimental diets were supplemented with enzymes at 0.5 g/kg (T2), organic acids at 1.0 g/kg (T3), Beta-pro at 0.2 g/kg (T4) or their combination (T5). The criteria of response were body weight, weight gain, feed consumption, feed conversion ratio, some blood constituents, carcass traits and economic efficiency. The obtained results can be summarized as follows: Positive effects of feed additives were observed on live body weight, daily weight gain and feed conversion of growing rabbits. There were no significant effects on blood parameters or carcass traits due to feed additives. It can be concluded that dietary Beta-pro (enzymes+probiotics) or a combination of enzymes, organic acids and Beta-pro at the tested levels can be used to improve the rabbit performance, with no adverse effects on carcass characteristics or blood parameters.

It was aimed to evaluate anti-GnRH vaccine efficiency on productive characteristics, seminal performance, size, and histology of testicles of lambs submitted to immunocastration. Twenty contemporary Texel lambs were evaluated, being 10 animals received two doses of 1 mL of anti-GnRH vaccine and 10 received two doses of 1 mL of saline, with an interval of 30 days. Seminal characteristics, weight and histological cut for the testicles, productive performance, and blood parameters were analyzed. Andrological monitoring was carried out every 30 days. All animals were kept on pasture of Urochloa spp. receiving daily supplementation protein-energetic by 90 days. There was effect of immunocastration on slaughter weight (44.3 vs. 48.3 kg), total gain (9.9 vs. 10.3 kg), daily gain (104.5 vs. 108.9 g/day), and feed conversion (5.83 vs. 5.97) respectively to immunocastrated and intact lambs. There was immunocastration effect on testicle weight (0.09 vs. 0.35 g), motility (4.5 vs. 61.0%), vigor (0.40 vs. 3.00), volume (0.09 vs. 0.74 mL) and swirling (0.20 vs. 2.70) in the third semen collection. Immunocastration through two doses of 1 mL of anti-GnRH vaccine with a 30-day interval between doses, causes infertility in sheep and can be adopted for lambs.

Abstract The aim of this study was to compare the effects of three feed mixtures based on various feed components, including extruded rice, and differing in the source and level of animal protein on rearing performance and biochemical and haematological blood parameters of piglets in the peri-weaning period. The experiments covered 96 piglets, crosses of PIC hybrid sows with a P76 boar that were divided into three experimental groups. The piglets from group I received a prestarter diet based on extruded wheat and protein of both plant and animal origin, whilst those from groups II and III were fed prestarter diets containing: group II - extruded rice (protein as in group I), and group III - extruded rice with protein components of exclusively animal origin. The addition of extruded rice and the increased content of animal protein in feed mixture improved the rearing performance of piglets (higher body weight gains and more efficient feed conversion ratio). The feeding of piglets with the diets containing extruded rice and increased animal protein components (III group) was also observed to stimulate lipid metabolism, which resulted in reduced plasma levels of LDL-cholesterol and in increased percentage of HDL-cholesterol, which contributed to increased blood levels of urea compared to the other experimental groups.

The objective of this study was to determine the crude protein requirements for juvenile jundiara fish, a hybrid of Pseudoplatystoma fasciatum X Leiarius marmoratus. A total of 240 juveniles of the hybrid, with an initial mean weight of 8.4 ± 1.41 g, were distributed in 15 fiberglass tanks (170 L) in a closed water recirculation and constant aeration system, with a density of 16 fish/tank. The experimental design was completely randomized with five treatments and three replications. The treatments consisted of diets with 32, 34, 36, 38 and 40% crude protein. Seventy days into the experiment the final fish weight and feed intake were measured. Two specimens from each experimental unit were collected for evaluation of carcass chemical composition, nutritional efficiency and blood parameters. The increase in crude protein content promoted the significant, increasing linear effect for mean weight gain, mean feed intake and specific growth rate, and decreasing effect for feed conversion. Significant differences were also observed in carcass chemical composition, nutritional efficiency, total plasma protein, glucose, cholesterol, triglycerides and lipase enzymatic activity. Thus, the increase in crude protein levels of up to 40% in jundiara diets promotes improvement in the productive performance of juvenile jundiara.

Abstract Background: This study aims to identify the effects of dietary Polygonatum sibiricum polysaccharide (PP) on growth performance and blood parameters in immunosuppressed chickens induced by cyclophosphamide (CY). Results: The results showed that PP enhanced the growth performance and immune response in chickens treated with cyclophosphamide characterized by increasing relative weight of thymus, total antioxidant capacity (T-AOC), superoxidase dismutase (SOD), albumin (ALB), immunoglobulin M (IgM), and antibody titers of Newcastle disease (ND) and avian influenza (H9), and decreasing feed conversion ratio (FCR) and malondialdehyde (MDA) level. Conclusions: PP enhanced chickens’ growth performance via improving antioxidant ability and alleviating CY-induced immunological stress.

The influence of subcutaneous injections of silver nanoparticles (AgNPs) on rabbit performance, hematological and biochemical parameters of blood, antioxidant status, and the residues of silver in meat and blood in two breeds (New Zealand White (NZW) and Jabali) of rabbits growing under high ambient temperature was evaluated. A total of 90 six-week-old rabbits (45 NZW and 45 Jabali) were randomly distributed into three equal treatment groups (control, 0.5 mg, and 1.0 mg AgNPs/kg body weight). The treated rabbits were injected twice a week for four consecutive weeks. The results revealed that AgNPs administration had no significant effect on average daily gain (ADG), feed intake, and feed conversion ratio (FCR). The NZW breed surpassed the Jabali breed in growth performance traits, carcass weight, dressing percentage, and cuts of mid parts and hind cuts. Administration of AgNPs had a significant effect on hematocrit (HCT) and platelet (PLT) values. Rabbits injected with AgNPs at a dose of 0.5 mg showed a lower plasma concentration of total cholesterol and triglycerides than that of control rabbits. The NZW breed had significantly low platelet, total cholesterol, and triglyceride values. Rabbits injected with 0.5 mg/kg BW had the lowest total antioxidant capacity and highest malondialdehyde (MDA) and glutathione peroxidase. The Ag residues were higher in blood than those in meat in treated rabbits. The local breed (Jabali) had significantly lower residues than the imported one (NZW) either in meat or in blood. However, the amount of accumulated silver in blood plasma and meat increased with increasing dose.

Haemolytic effects of different extracts of five indigenous plant seeds viz. Datura innoxia (Mill) (Shada Dhutra), Clerodendrum viscosum (Vent.) (Vat), Amoora rohituka (Roxb.) Wt. ct. Arnott (Pitraj), Acacia auriculiformis A. Cunn. Ex. Benth. (Akashmoni) and Pongamia pinnata (L.) Pierre (Karinja) were studied upon a predatory fish, Singhi, Heteropneustes fossilis (Bloch) under laboratory conditions. Toxicants inducing effects on the blood parameters included decreased RBC and WBC counts, low haemoglobin percentage and decreased PCV (packed cell volume), MCV (mean corpuscular volume) and MCH (mean corpuscular haemoglobin). Haemolysis action included shrunken or swollen RBCs, granulated nuclei of RBCs and pyknotic nuclei of WBCs, clumping of RBCs and syncitium of RBC matrix. Damage of blood cells with absolute ethyl alcohol extract was most pronounced with all of the seed extracts. The order of toxicity of the five seed extracts on the blood parameters of Singhi was: D. innoxia < A. auriculaerformis < P. pinnata < C. viscosum < A. rohituka seed extracts. On the basis of haemolysis the toxicity was: A. rohituka > C. viscosum > P. pinnata > D. innoxia > A. auriculiformis seed extracts.
