High potency growth promoter implants (HGPs) are widely used under feedlot conditions but there are few reports under grazing conditions. The study’s goal was to assess the effect of HGPs on the average daily gain of steers fattened in pastures. A total of 57 crossbreed steers (Hereford × Angus)—initial body weight = 356.65 kg ± 5.04 (SEM)—were randomly allocated to one of three groups: Control without HGP (n = 19), Synovex group (n = 17), and Revalor group (n = 21). The fattening period was 67 days using paddocks of Lolium perenne L. and Trifolium repens L. Body weight was recorded three times in the period. The data were analyzed using an analysis of covariance with a level of significance of 5%. The average daily gain (ADG) (1.55 ± 0.07 and 1.48 ± 0.09 kg/d) and the total weight gain (103.4 ± 4.9 and 99.2 ± 5.8 kg) were similar for Revalor and Synovex, respectively (p > 0.05). Moreover, HGP groups showed higher ADG and total weight gain (p < 0.01) than the control group (ADG = 0.93 ± 0.08 kg/d and a total weight gain of 62.2 ± 5.2 kg). Final body weights were 527.8 ± 8.5 kg and 512.2 ± 9.9 kg for Revalor and Synovex, respectively; and 479.9 ± 10.1 kg for Control. In conclusion, grazing-finished steers showed better performance when high potency HGPs were used, improving the ADG and final live body weight, generating a marginal income that justifies the use of the technology under grazing conditions

For correcting, the nutritional imbalance of rice straw feed diet by supplementing energy and protein rich concentrate (rice bran) an experiment was carried out in growing male goats at Agriculture Research Station (Goat), Bandipur, Tanahun from November 2009 to Januwary 2010. Twelve goats of 6-7 months of age and similar body weight were divided into four treatment groups having three animals in each group by using complete randomized design. Four types of diet were formulated for these experimental animals. The animals of control group (treatment 1) were provided UTRS, Raikhanayo and concentrate mixture at the rate of 65, 25 and 10% of dry matter requirement, respectively. Dry matter requirement of treatment 2 was fulfilled by providing urea treated rice straw (UTRS), Raikhanayo and rice bran @ 65, 25 and 10%, respectively. Treatment 3 received dry matter requirement by UTRS, Raikhanayo and rice bran @ 55, 25 and 20%, respectively whereas treatment 4 got @ 45, 25 and 30 percent UTRS, Raikhanayo and rice bran, respectively. The study revealed that there was no significant effect in fodder and UTRS intake between diet groups except rice bran (P<0.001). Likewise, there was highly significant (P<0.001) effect in total dry matter intake between diet groups. The highest body weight gain was observed in treatment 4 (17.5 ± 1.8 kg) followed by treatment 3 and 2 (15.66 ± 1.15 kg and 15.5 ± 3.27 kg, respectively). The lowest body weight gain was noted for treatment 1 (14.5 ± 1.80 kg); however, it was also found non-significant between diet groups. Average daily gain was recorded highest in treatment 4 (50 g /day) followed by treatment 2 (31.44 g /day) whereas average daily gain for treatment 1 and 2 were recorded similar (27.77 g /day).DOI: http://dx.doi.org/10.3126/njst.v12i0.6480 Nepal Journal of Science and Technology 12 (2011) 55-60

The combined effect of homobiotics, probiotics based on recombinant strains of g. Bacillus, & enrofloxacin on the dynamics of body weight gain in geese was studied. According to the principle of steam-analogs, one control and five experimental groups of 10 goslings in each group were formed. Gosyatam experimental groups used homobiotics vetom 15.1; vetom 13.1 incombination with enrofloxacin followed by replacement with a probiotic preparation Vetom 1.2. The absolute body weight and average daily gain in geese under the influence of the studied drugs increases. The severity of the effect depended on the pharmacological composition of the drugs used. The maximum absolute weight gain was observed when using the drugs according to the scheme: vetom 13.1 at doses of 25–50 mg/kg for 16 days, with further use of a 10% enrofloxacin solution at a dose of 0.5 ml/kg for 5 days and in The experiment period was 1.2 at a dose of 50 mg/kg for 16 days. After the cessation of the use of drugs, the growth rate increased for 30 days when prescribing the drugs according to the scheme: veto 13.1 at a dose of 50 mg/kg for 16 days and with further introduction of homobiotic veto 1.2 into the bird in a dose of 50 mg/kg for 16 days. The maximum average daily gain in live weight of geese was observed in the period from the 16th to the 32nd day with the administration scheme: homobiotic vetom 13.1 at a dose of 25 mg/kg of body weight 1 time per day for 5 consecutive days, then every other day for 16 days, then daily 10 % solution of enrofloxacin at a dose of 0.5 ml/kg of body weight for 5 days, then vetom 1.2 at a dose of 25 mg/kg once a day for 16 days in a row. And the maximum average daily gain in the post using period of the drug was observed on the 32nd day of the study according to the scheme: homobiotic veto 15.1 at a dose of 50 mg/kg of body weight 1 time per day for 16 days, then daily with vetom 1.2 at the same dose 1 once a day for 16 days. The studied drugs in the applied doses did not have a toxic effect on the physiological state of geese.

Stimulation Of

Phytogene feed additives (phytobiotics) are plant origin compounds used in animal nutrition in order to improve their productivity by improving the production performance of animals, feed properties and the quality of food of animal origin. These additives stimulate animal growth by using their natural and physiological potentials and mechanisms providing conditions for the realization of the genetically projected production volumes. Data on the use of phytobiotics as growth stimulators are incomplete and often very contradictory, especially those related to their impact on the health and performance of weaned pigs. Given the relevance and importance of these issues the feeding trial was organized by the group-control system. The experiment lasted for 40 days and it was divided into two phases of 20 days each. Trial was conducted on 24 piglets, F1 generation of Swedish Landrace and Pietrain, weaned from sows at the age of 35 days. Tests were carried out on piglets, with an average body weight of 8.61?1.59 kg, which were subjected to one of the two feeding treatments immediately after weaning. The control group was fed with a mixture without growth promoters, while the experimental group received a diet containing preparation of phytobiotic (Enviva EO 101, Danisco Animal Nutrition) in the amount recommended by the manufacturer (0.1 kg/t). The mixtures for piglets nutrition were formulated in accordance with the recommendations of the NRC (1998), and AEC (1993) and they met the nutritional requirements completely. During the experiment, there was no disturbance of health and/or the manifestation of clinical signs of disease. The control group, fed with the diet without added growth stimulators, achieved body weight (25.32?6.31 kg), average daily gain (0.42?0.12 kg), consumption (0.89 kg) and feed conversion (2.119 ) normal for a given race, age and housing conditions. The use of preparation of phytobiotics as growth promoters, led to better production results in regard to the control group, which was based on higher body weight (27.19?4.77 kg), higher average daily gain (0.46?0.09 kg) and better feed conversion (2.043). The use of phytobiotic, as an alternative option in growth stimulation of weaned pigs, has its nutritive, medical and economic justification.

Abstract The aim of this study was to evaluate the non-carcass components (NCC) of Berganês ecotype lambs of different sexual classes and genotypes using univariate and multivariate statistics, carrying out two experimental trials. In order to evaluate the effects of the sexual class, non-castrated males (BNC), castrated males (BC) and females (BF) of Berganês ecotype lambs were used, with mean initial body weight of 27 ± 3.1 kg. To evaluate crossbreeding, non-castrated male lambs of the genotypes Berganês (BG), Berganês × Santa Inês (BSI) and Berganês × Dorper (BD) were used, as well as the control Dorper × Santa Inês (DSI), all with mean initial body weight of 28 ± 3.8 kg. The weight and yield of the total by-products was higher for BNC. Regarding the genotype, BSI showed higher weight and yield of internal fat, but the weight and yield of the total by-products was higher for BG and BD. In factorial analysis (FA), the NCC, more correlated with empty body weight (EBW) and total weight gain (TWG), showed higher eigenvectors for factor 1. For factor 2, the weights and yields of internal fat and total viscera obtained higher eigenvectors. The discriminant analysis (DA) classified 100% of individuals in their respective sexes and genotypes. Therefore, the FA indicated that, among the NCC evaluated, the weights of liver, kidneys, GIT, skin and feets are determinant for obtaining EBW and TWG. The classification achieved by the DA indicates that the sexual classes and genotypes are heterogeneous.

The efficacy of tulsi (Ocimum sactum) and neem (Azadirachta indica) leaves extract as a growth promoter were studied in broiler. A total of 40 day-old broiler chicks were purchased from Kazi hatchery and after three days of acclimatization the chicks were randomly divided into four groups (n=10). No vaccination schedule was practiced and no antibiotic was added in ration of group A, B, C, and D respectively. Group A served control without any supplements while group B, C and D were supplemented with combination of tulsi and neem extract @ 1 ml, 2ml and 3 ml/liter of drinking water. Live body weight gain was recorded weekly up to 6th weeks and hematological studies were performed at 21st and 42nd day of experiments. At the end of 42nd day of experiment final body weight of group A, B, C and D were 1561± 12.10 g, 1698± 12.87 g, 1608± 12.04 g and 1763± 13.28 g, respectively. The birds of group D utilized their feed more efficiently among the treatment groups (p<0.05). The net body weight gain were, 1533± 11.98 g, 1443± 11.32 g and 1588± 12.10 g in treated groups compared to control group (1393± 11.07 g ) and total net profit per broiler was 19.08, 40.10, 20.68 and 45.07 Taka , respectively. Hematological parameterss (TEC, PCV, Hb and ESR) were not significantly changed among the treated and control group suggesting no side effects of herbal extracts in broiler. It can be concluded that tulsi and neem extract is economic and safe in broiler production.DOI: http://dx.doi.org/10.3329/bjvm.v11i1.17728 Bangl. J. Vet. Med. (2013). 11 (1): 1- 5

The purpose of the research is increasing the average daily gain of animals due to the use of the Bisolbi drug. The effect of Bisolbi preparation based on Bacillus subtilis H-13 1.5×108 (LLC «Bisolbi-Inter») on the biochemical and productive life of calves was studied. The scientific and production experiment was carried out on the basis of a dairy farm of the State «Kupinskoe» Unitary Enterprise of the Samara region involving 30 Holstein-Friesian calves. The biological effect of the drug is provided due to its adsorption properties, the ability to enhance the activity of a number of enzyme systems and increase the digestive and systemic immunity of the body. The drug use increases the integration intensity of animals: the amount of total protein in the blood serum of calves of the experimental group at 120 days of age was higher by 8.9% (p<0.05), albumin – by 9.2% (p<0.01), compared with the animal data of con-trolled group. The Bisolbi indication contributed to an increase in the intensity of carbohydrate-lipoid metabolism: the cholesterol amount was higher by 23% (p<0.01), the glucose content – by 0.4 mmol/l (p<0.05) in the blood of 120 day old calves of the experimental group, compared with the data of controlled animals. It was found that the body weight of calves in the control group of 100 days age was 105.23±2.11 kg, in the experimental group – 108.6±2.19 kg, which is 3.37 kg higher. The average daily weight gain of animals in experimental group was signif-icantly higher by 0.075 kg (p<0.01). At 120 days of age, the body weight of the experimental calves was higher by 4.19 kg (p<0.05), the average daily weight gain by 0.080 kg (p<0.05), compared with the data of the controlled ani-mals. The indication of Bisolbi 5-10 ml (LLC «Bisolbi-Inter») to calves daily for 2 months resulted in an additional profit constructively of 137 rubles from each head.

This study was carried out to evaluate the feeding effect of high yielding fodders (HYF) on feed intake and growth performance of growing Hilly Brown Bengal (HBB) goat. For this purpose, a feeding trail was conducted with 16 growing HBB kids (4 to 5 months) by dividing equally in four groups having four replicates for a period of 75 days. The goats in group T0 (control) received natural grass along with 101.30g concentrates and adlibitum cowpea hay, whereas in group T1, T2 and T3, only natural grass was replaced by BLRI Napier 3, BLRI Napier 4 and Ruzi fodder, respectively. Total dry matter intake (DMI), roughages DMI, crude protein intake (CP), body weight gain (kg), average daily gain (g) and forth night body weight gain (g/day) were studied. Results revealed that, DMI (288.39, 285.71, 293.48 and 301.35 g/day in group T0, T1, T2 and T3, respectively), body weight gain (3.60, 3.74, 3.73 and 3.77 kg in group T0, T1, T2 and T3, respectively), average daily gain (47.32, 49.16, 49.12 and 48.92 g in group T0, T1, T2 and T3, respectively) and feed conversion ratio (6.2, 5.9, 6.0 and 6.1 in group T0, T1, T2 and T3, respectively) of HBB kids were not differed significantly (P>0.05) for all the treatment groups. The DMI from roughages (196.2, 193.5, 201.3 and 209.2 g/day in group T0, T1, T2 and T3, respectively) and CP intake (38.7, 42.1, 48.3 and 38.8 g/day in group T0, T1, T2 and T3, respectively) were significantly varied (P<0.05), while highest CP intake was found in the treatment group T2. Forthnight body weight (g/day) was not significantly (P>0.05) gained with feeding of HYF for all the treatment groups. From this study, it can be concluded that, growing HBB kids could equally be supplied with either BLRI Napier 3 or BLRI Napier 4 or Ruzi fodder in addition to ad libitum cowpea hay for better voluntary feed intake and growth.

The effect of Bisolbi drug based on Bacillus subtilis on the physiological, biochemical and productive parameters of calves was studied. The research and production experiment was carried out in a dairy farm “Kupinskoe” of Samara Region on 30 calves of the Holstein-Frisian breed. The drug increases the intensity of the anabolic processes in animals: the amount of total protein in blood serum of calves of the experimental group at 120 days of age was higher by 8.9% (p≤0.05), albumin 9.2% (p≤0.01), compared with control animals. The purpose of Bisolbi contributed to the increase in the intensity of carbohydrate-lipid metabolism: cholesterol was higher by 23% (p≤0.01), glucose 0.4 mmol/l (p≤0.05) in blood 120-day calves of the experimental group, relative to the data of the control group. It was found that the body weight of calves in the control group at 100 days of age was 105.23±2.11 kg, in the experimental group -108.6±2.19 kg. The average daily gain in the experimental group was significantly higher by 0.075 kg (p≤0.01). At 120 days of age, the body weight of the experimental calves was higher by 4.19 kg (p≤0.05), the average daily increase by 0.080 kg (p≤0.05), relative to the control animals.

This study was conducted to evaluate the effects of a toy on the behaviour and body weight of weaned pigs after mixing. Two groups (192 pigs in total, control: without toy; treatment: with toy placed on the floor) of weaned pigs housed in pens (1.8 m × 1.4 m, 4 pigs/pen) were This study was conducted to evaluate the effects of a toy on the behaviour and body weight of weaned pigs after mixing. Two were observed with the aid of video technology for nine consecutive hours in the early (days 1 and 2) and late (days 38 and 39) period after mixing. Bodyweight of pigs at the end of the study (Mann-Whitney U-test, Z = –2.46, P = 0.01) and the average daily gain (Z = –2.75, P &lt; 0.01) were 10% higher in the treatment group than in the control group. The presence of the toy in the pen influenced the pig behaviours. In pens enriched with toys, there was an increase in feeding behaviour and a decrease in agonistic and belly nosing behaviours. Toy supply reduced negative social behaviours and thereby improved the bodyweight of weaned pigs. The results of this study suggest that toys used as environmental enrichment are useful for enhancing pig welfare and effective for farmers.
