The Impact

Abstract The aim of this study was to determine the influence of the different proportion of perennial ryegrass (Lolium perenne L.) in the meadow sward on its fodder value and daily weight gain of Highland cattle. The research was carried out on meadow sward with natural undergrowth that was cultivated by sowing perennial ryegrass. When preparing the sward for sowing, around 40% of it was damaged with a rotary tiller. The sowing rate for perennial ryegrass seeds was varied and amounted to 5, 10 and 15 kg ha−1. As a result, the following treatments of meadow sward were obtained and distinguished: semi-natural sward without sowing as the control, and three experimental treatments with approximately 18, 36 and 55% share of perennial ryegrass in the meadow sward. The animals were kept in a cowshed. In the nutritional part, the impact of feeding the obtained sward on the daily weight gain of Highland bulls and heifers was assessed. The obtained results showed higher gains in both bulls and heifers fed with sward from grasslands with a greater proportion of perennial ryegrass. The weight gain of the animals resulted from the nutrition, i.e. the quality of the feed obtained from the experimental objects. During the control fattening period, the bulls’ average daily weight gain ranged from 649 g to 714 g, while for heifers 556 g to 598 g. Statistical significance (P ≤ 0.05) in body weight gains in both bulls and heifers was shown already at 36% of perennial ryegrass in the meadow sward.

The majority of lamb losses occur within the first two weeks of life, with cold stress being a major cause of lamb morbidity and mortality. This study investigated the effect of insulating lamb jackets on newborn lambs. One hundred and four newborn lambs were randomly allocated by birth date to two treatment groups, (a) non-jacketed (n = 52) or (b) jacketed (n = 52), for fourteen days after birth. The live weights of lambs were recorded regularly up to 21 days, and average daily weight gains were calculated from these data. For the first two days after recruitment to the study, surface and body temperatures of lambs were also recorded. The jackets significantly increased the lambs’ surface temperatures, providing a warmer microclimate and reduced cold stress for jacketed lambs. There was no significant effect of the insulating jackets on estimated body temperatures, live weights or average daily weight gain of the lambs in this study. There were no detrimental effects of the jackets, and no rejection of lambs occurred.

A study was conducted to determine the efficacy of three most commonly used growth promoters from different pharmaceutical companies on growth performance of hybrid walking catfish (Clarias batrachus × Clarias gariepinus). The experiment was done in the wet laboratory of the Department of Aquaculture, BAU, Mymensingh, with a total of 10 aquaria and 160 fish having mean initial weight of 6.3 ± 0.48 g. The three growth promoters, “Charger gel” from Fishtech (BD) Ltd., “Growth gel” from Advance Agrotech (BD) Ltd. and “Hepaprotect-aqua” from Renata Animal health Ltd., were used in separate nine (9) aquaria at recommended, lower dose and higher dose respectively. One aquarium was used as control (diet without any growth promoter). The fish were fed with paragon nursery floating feed at 20% of body weight in each aquarium for 28 days. Doses of Charger gel were given as 80, 60 and 100 mg/20 g feed/day, that of Growth gel, 0.14, 0.12 and 0.16 ml/20 g feed/day and of Hepaprotect-aqua, 30, 15 and 50 mg/20 g feed/day. Re-circulatory system was used throughout the experimental period. By applying recommended, lower and higher dose of “Charger gel”, mean final weights were found as 23.0, 21.9 and 35.9 g; average daily weight gain as 0.60, 0.56 and 1.06 g and specific growth rate (SGR) as 2.01, 1.93 and 2.70% respectively. For “Growth gel”, mean final weights were found as 22.8, 17.3 and 31.1 g; average daily weight gain as 0.59, 0.39 and 0.88 g and SGR as 1.99, 1.57 and 2.48 % respectively. For “Hepaprotect-aqua”, mean final weights were found as 24.2, 17.5 and 28.2 g; average daily weight gain as 0.64, 0.40 and 0.78 g and SGR as 2.09, 1.58 and 2.32% respectively. In all the cases survival rates were 100%. All the three growth promoters showed better results at their higher doses in comparison to their results in lower and recommended doses. However, in average Charger gel showed the best result than the other two growth promoters. This information on the efficacy study of growth promoters needs to be disseminated to the farmers for improved fish production.Asian J. Med. Biol. Res. March 2017, 3(1): 103-108

The experiment was conducted to optimize the dose of 17?-methyl testosterone (MT) during masculinization of tilapia (Oreochromis niloticus) fry. Five treatments were designed with various doses of hormone to find out the most effective one. The treatments were designated as T1 (0 mg MT/kg), T2 (40 mg MT/kg), T3 (50 mg MT/kg), T4 (60 mg MT/kg) and T5 (70 mg MT/kg). MT was administered orally by using nursery feed and Ethanol (as hormone carrier solvents) diet to tilapia fry for 28 days in hapa. After completion of the trial period of 28 days nursing of the experimental fry was continued for further 2 months with commercial feed. At the end of experiment the sex ratio was      determined by examining gonad after dissecting the fish. Growth performance was monitored by recording the morphometric characteristics i.e. weight gain (g), average daily weight gain (g). The analysis of growth data showed significant variation in weight, % weight gain, SGR (% /day) of fish among the different treatments. SGR increases with the increase of hormone dose. The present study demonstrated that all MT receiving treatments showed a significantly (p<0.01) higher male proportion (94.28%) than control (48.57%). The dose of 60 mg MT/kg of feed resulted in maximum male population (94.28%). The result indicated that the optimum dose of MT hormone was 60 mg /kg with a feeding period of 28 days after hatching.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.11052   J. Bangladesh Agril.

ABSTRACT The aim of this study was to determine the influence of gender on pre-weaning growth, yield and weight of primal cuts of the carcass of Blackbelly x Pelibuey lambs. 16 twin lambs were used. The lamb gender was the fixed factor. The variables evaluated were: body weight at birth and at weaning, average daily weight gain, weight and yield of carcass and primal cuts: neck, arm, thorax, abdomen and leg. Gender did not affect (P>0.05) body weight at birth. However, the pre-weaning average daily weight gain and body weight at weaning were affected (P<0.05) by the gender. Hot carcass yield and weight and primal cuts were not affected (P>0.05) by the gender of the lamb. Nevertheless, the area of the Longissimus dorsi muscle and cavity fat were different between males and females (P<0.05) 11.5±0.73cm2 and 198±0.05 g vs 9.3±0.73cm2 and 282±0.05g, respectively. In conclusion, in twin lambs Blackbelly x Pelibuey males had greater average daily weight gain and body weight at weaning than females. Carcass yield and weight and primal cuts were not affected by the gender of the lamb. However, males had greater area of the L. dorsi muscle than females and these in turn had a greater amount of cavity fat than males.

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.

Young Cattle

The protein, vitamin and mineral supplements have been developed and it was studied the efficiency of feeding with them the young cattle in the composition of the grain production. The scientific and farm experiment has been carried out during 62 days. The study was conducted in four groups of bulls with 12 heads in each. The initial live weight at the beginning of the study was about 300–310 kg. Differences in feeding were in the fact that the grain forage for young animals of group I included PVMS No. 1, II – PVMS No. 2, III –PVMS No.3, IV – PVMS No 4. The grain feed is represented mainly by barley. The protein, vitamin and mineral supplement replenished 20 % of the deficient protein. It was discovered that concentration of hydrogen ions was practically at the same level in the rumen contents of steers of different groups. As for level of ammonia, VFA, total nitrogen, ciliates in the young cattle of I, II and III groups, the differences were insignificant. The concentration of ammonia of group IVcompared to I, II and III group was higher by 15.58, 23.61 and 21.9 %, VFA – by 6.7, 19.4 and 11.1 %, total nitrogen – by 3.32, 31.44 and 24.03 %, ciliates – by 4.35, 14.29 and 9.09 %, respectively. The research results showed that digestibility of protein, fiber and BEV was higher in the fourth group by 1–7 % compared with the rest groups (P>0.05). A slight increase in nitrogen deposition was found in IV group of young animals (by 4.7–11.9 %) receiving PVMS with AFA as a source of protein. The use of calcium and phosphorus by animals was almost at the same level. The research helped to determine that the average daily weight gain of animals of all the groups was within the range 629–710 g. The highest was in the fourth group consuming PVMS No. 4 with AFA as a protein component; the second place in terms is occupied by group I – 660 g, consuming PVMS No. 2, which included lupine, AFA and standard DKMK No. 1; PVMS No. 3 with depleted phosphate used as a source of phosphorus, took the last place in terms of this indicator – 629 g. Feed cost per 1 kg of weight gain was the lowest in IV group – 8.77 feed units, in I, II and III groups, it was higher by 8.32 %; 13.68 and 10.83 %, respectively. The cost of sold products from one animal during experiment turned out to be higher for steers that received PVMS No. 4 as compared to I, II and III groups by 6.82, 11.36 and 9.1 %, respectively.

The effect of the probiotic preparation Vetom 1.2 on the basis of Bacillus subtilis VKPM B-10641, Bacillus amyloliquefaciens VKPM B-10642 and Bacillus amyloliquefaciens VKPM B-10643 in different doses on the correlation interactions between the parameters of turkey hemoglobin exchange, blood erythrocytes and blood red blood cells direct and total bilirubin, total protein and serum albumin was studies. Correlations were calculated using Spearman formula, the reliability of correlations was checked by Student. The formulation was used for turkeys once a day for 30 days in doses of 12.5; 25; fifty; 75 and 100 mg / kg body weight. It was found that Vetom 1.2 in minimal doses leads to an inverse correlation between iron and total bilirubin, direct bilirubin, total protein and albumin, an increase in the concentration of the formulation leads to the disappearance of this effect with a gradual subsequent decrease in this indicator. Vetom 1.2 in doses up to 50 mg / kg leads to an inverse correlation between the concentrations of hemoglobin and direct bilirubin, total protein and serum albumin, at a dose of 75 mg / kg there is a direct correlation between these indicators, and at a dose of 100 mg / kg returns a negative correlation. The probiotic preparation Vetom 1.2 leads to a direct dependence of the concentration of bilirubins (total and direct) in serum on the concentrations of hemoglobin and red blood cells when used in most doses, except 75 mg / kg, which reduces the correlation.
