The experimental materials comprised 400 Ross 308 chickens (200 ♂ and 200 ♀), divided randomly into four groups kept in 16 pens, as follows: a negative control group (I) – a diet without additives, a positive control group (II) – a diet supplemented with a combination of the antibiotic growth promoter flavomycin (10 mg kg⁻¹ feed) and the coccidiostat robenidine (500 mg kg⁻¹ starter and grower feed), and two experimental groups – diets supplemented with chemically standardized propolis – 10 mg kg⁻¹ feed in group 3 and 50 mg kg⁻¹ feed in group IV. The body weights of chickens were determined once a week. Feed intake, mortality and culling rates were monitored regularly. At the end of the experiment, on day 42, 12 chickens (6 ♂ and 6 ♀) were selected from each group for slaughter and carcass quality analysis. The final body weights of chickens, feed intake (kg) per kg body weight and carcass weight during the rearing period did not differ significantly between groups. The lowest feed intake per kg lean meat was noted in chickens fed a diet with 50 mg propolis/kg feed (3.457 kg), and the highest – in broilers fed a diet with 10 mg propolis/kg feed (3.611 kg). The weight of carcass and selected carcass parts (neck, breast, legs) tended to increase in chickens that received propolis, although the noted differences were statistically non-significant. The percentage content of legs in the carcass was significantly lower in chickens fed a diet with an antibiotic growth promoter (AGP). The legs of chickens fed 50 mg propolis had a significantly higher muscle content and a lower fat content, compared with the legs of birds fed a diet with AGP.

An experiment was conducted to evaluate the growth performance of Nile tilapia fed with supplemental feed (25% crude protein) at 50% satiation. Juvenile Nile tilapia (average weight 6.4 g) were stocked in an earthen pond at 2.4 fish m⁻² . The pond was fertilized twice weekly with a mixture of superphosphate and urea fertilizer (68 kg ha 1⁻¹). The annual fish yield was 6880 kg ha⁻¹. The mean weight of harvested fish ranged from 110 to 250 g. The food conversion ratio (FCR) was 0.82, the average daily weight gain (ADG) was 0.9 g d⁻¹ and the specific growth rate was 1.55 % d⁻¹. This study demonstrated that 50% satiation feeding is an effective feeding rate for improving the production of Nile tilapia cultured in a fertilized, freshwater earthen pond.

Lipid oxidation is the primary cause of deterioration in the quality of frozen meat and meat products. Oxidative deterioration of meat lipids during frozen storage can directly affect the colour, flavour, texture, nutritive value, and safety of food. Natural antioxidants reduce lipid oxidation and as a consequence may improve meat quality. In the present study we investigate the effect of three levels of dietary vitamin E on animal growth performance and on meat oxidation. HPLC analyses were performed in order to assess a-tocopherol levels in blood serum and its deposition in muscles. The oxidative stability of muscle was examined over 7 days of refrigeration storage by means of thiobarbituric acid reactive substances (TBARS). We concluded that supplementation with vitamin E augmented a-tocopherol levels in blood serum and muscles from pig samples receiving 300 mg/kg feed. Moreover lipid oxidation in chilled meat was successfully reduced.

Growth performance parameters and selected quality traits of meat and femoral bone of broiler chickens fed diet supplemented with amorphous diatomaceous earth. This study was aimed at analyzing the effect of the addition of amorphous diatomaceous earth to feed on growth performance parameters and selected quality traits of meat and femoral bone of broiler chickens. The study was conducted with 60 fast-growing Ross 308 broiler chickens, reared until 42 days of age and divided into a control group (C) and two experimental groups (D2 and D4) (20 birds each). The diatomaceous earth (diatomite) was administered to the birds’ feed from the groups D2 - 2%, D4 - 4%. Individual body weight, feed intake and mortality of chickens were controlled. On day 42 of rearing, 6 males were selected from each group for slaughter followed by dissection. Dressing percentage, content of muscles and giblets (gizzard, liver and heart), were calculated, and in samples of breast and leg muscles the chemical and physicochemical properties were analyzed. Resistance of the femoral bone to fractures was determined. The addition of diatomite did not affect the health status of chickens. Significantly higher body weight at 42 days of rearing was noted in the group C vs D4 (P ≤0.05). Significantly higher (P ≤0.01) content of pectoral muscles and lower (P ≤0.05) fat in the carcass of D2 vs C were noted. The addition of diatomaceous earth did not affect the chemical composition of the breast muscles. The fat content in leg muscles was significantly reduced (P ≤0.05) and water content was increased (P ≤0.05) in D2 vs C. Femoral bones of D4 birds were significantly more resistant (P ≤0.05) to breaking than in C. Direct relationship between the amount of diatomite and the strength of the femur was found. The most optimal supplementation was considered as 2%.

The aim of this study was to evaluate the effects of dietary supplementation of bamboo leaf extract (BLE) on the growth performance, antioxidant traits, immune function, and lipid metabolism of weaning piglets. After weaning at 21 days, two hundred and forty healthy piglets (Large White × Landrance) were randomly assigned to 4 treatments with 6 pens and 10 piglets per pen. The control group (Ctr) received a maize-soyabean based diet, and the test groups received the control diet plus 0.5%, 1%, or 2% (w/w) BLE, respectively. The experiment was carried out for 5 weeks. At the end of it, average daily feed intake in the 1% BLE group was decreased (p < 0.05). Plasma concentrations of malondialdehyde were decreased with supplementation of 1% and 2% BLE. Immunoglobulin G concentrations and lysozyme activity in plasma were significantly increased in piglets supplemented with BLE. Diets with 1% and 2% BLE increased (p < 0.05) plasma concentrations of low density lipoprotein-cholesterol and reduced (P < 0.01) high density lipoprotein-cholesterol levels. Higher triglyceride concentrations were observed in the 0.5% (P < 0.01) and 2% (p < 0.05) BLE groups. In conclusion, these novel findings demonstrate that supplementation of BLE to the diet improved the antioxidant activity, immune function, and lipid metabolism of weaning piglets.

This study was conducted to investigate the effects of crude Aloe vera polysaccharide (AVP) on the growth performance and immune function of weaned piglets. A total of 200 (Landrace Yorkshire × Duroc) weaned pigs at 21 d with initial 8.88 ± 0.49 kg body weight (BW) were allotted to one of four dietary treatments in a randomized complete block design according to their sex and BW (5 replicates with 10 pigs per pen, 5 gilts and 5 barrows). Dietary treatments included one basal diet, and three diets with AVP supplementation (0.05%, 0.1%, or 0.2%). Average daily gain (ADG), average daily feed intake (ADFI), and feed:gain (F:G) ratios were calculated at the end of the experiment. Separated serum samples from each treatment were assayed at the end of the experiment for the concentrations of cytokines and the blocking rate of antibodies against classical swine fever virus (CSFV). Supplementation of AVP at 0.1% improved (P < 0.05) ADG compared with the control group. No significant differences in ADFI or F:G were observed between AVP-treated and untreated control piglets. All AVP-treated pigs had a significantly lower incidence of diarrhoea (P < 0.05) when compared with control pigs. Feeding AVP resulted in increasing (P < 0.01) IL-2 and IFN-γ (at 0.1% and 0.2%) and IL-4 (at 0.05%, 0.1% and 0.2%), and in no significant changing of IL-10 (P > 0.05). Supplementation of AVP at 0.05%, 0.1% and 0.2% increased (P < 0.01) the blocking rate of antibodies against CSFV. These results indicate that dietary supplementation with dietary AVP enhanced growth performance in weaned piglets by improving immune function, decreasing the incidence of diarrhoea

Two complete diets for weaned piglets were analyzed. Control diet I was composed of soybean meal, ground barley, ground wheat, premix and acids. Experimental diet II was supplemented with 0.1% Vilocym, a blend of herbal extracts (Azadirachta indica, Curcuma longa, Allium sativum, Andrographis paniculata, Solanum nigrum) and sodium-calcium aluminosilicates. Nutrient digestibility was determined by a simple balance method, on 16 young barrows [(Polish Large White x Polish Landrace) x Duroc] with average initial body weight of 25 kg, assigned to two dietary treatments. A five-day experimental period proper was preceded by a seven-day adjustment period. A production trial was carried out on a pig farm, and it involved 240 weaners with average initial body weight of 20.5 kg, divided into two groups. Each group comprised four pens, with 30 animals per pen. The experiment lasted 30 days. Dietary supplementation with herbal extracts and aluminosilicates improved the digestibility of crude fat, total protein and organic matter. Weaned piglets fed Vilocym were characterized by higher daily gains than control group animals (725 g vs. 665 g, P ≤ 0.05). Feed consumption per kg body weight gain was significantly lower in group II (2.14 g/kg vs. 2.33 g/kg, P ≤ 0.05).

Possibility of reduction of protein level in feed mixtures of similar content of amino acids digestible in the small intestine and its influence on fattener’s performance and nitrogen retention were determined. Thirty pigs (35 kg) were divided into 3 groups. The control animals were fed with diets with crude protein level suggested by polish pig feeding standards (Normy żywienia... 1993) – 17% in grower and 15% in finisher diet. In the experimental groups (I and II) the protein level was reduced about 10 or 20% respectively. No significant effect on feed intake, weight gains and feed utilization was found. The animals from the both experimental group utilized less crude protein (P=0.001) than in Control group. The significant (P=0.001) reduction in nitrogen excreted in urine and total N-excretion in both group with reduced protein level in feed mixtures, were observed. Nitrogen retention in g/day was higher for group I compared to other groups and N-retention : N intake were significantly higher (P<0.05) in both experimental groups. The reduction of crude protein level in the experimental diets did not affect slaughter performance but in group II the tendency to increase (P=0.064) in back fat thickness and decrease meat content in carcass, were observed. The results suggest that lowering the protein level in diets for high-meat crossbred pigs (Polish Large White × Polish Landrace) × (Hampshire × Pietrain) from 170 and 150 g kg⁻¹ to 136 g and 115 g kg⁻¹ in grower and finisher diets, respectively, but supplemented with synthetic amino acids, did not impact negatively production results of fatteners, but decreased nitrogen emission to the environment and cost of feed.

Background. The viviparous sailfin molly, Poecilia latipinna (Lesueur, 1821), is a popular ornamental fish that thrives in a wide range of salinities. It is well known that salt water of intermediate salinity (25‰) is suitable for mollies, especially for healthy breeding. Nutrition has been recognized to have a profound effect upon gonadal development and fry production in fish. Hence, the present work was carried out to evaluate the suitability of different practical diets, such as oyster meat, live tubificid worms, and formulated feed, on fry production, gestation period, and growth performance of P. latipinna in salt water. Materials and Methods. Materials and Methods. A trial was conducted on P. latipinna in salt water (25‰ salinity) to evaluate the suitability of oyster meat, live tubificid worms, formulated feed, and a mixture of these three diets, on breeding and growth. Results. Irrespective of diet, the gestation period was consistently 28 days. Maximum fry yield (460 fry) and better growth performance was obtained in brooders and juveniles respectively fed mixed diet. A positive correlation existed between the loss of weight due to spawning in the brooders and fry production in all dietary treatments. Among the dietary treatments there was a significant difference (P < 0.005) in growth performance parameters, such as weight gain [g], food conversion ratio (FCR), and specific growth rate (SGR). Conclusion. Among the four dietary treatments, the mixed diet performed well in both breeding and rearing experiments. Hence in commercial breeding units, mixed feeding regimen could be adopted with mollies in salt water.
