Change in Properties of Bitumen Used for Road Construction in Bitumineral Mixtures

Premature destruction of asphalt concrete can be caused by the aging of bitumen, which is associated with a change in the physical and chemical properties of bitumen. The article shows that in most cases, the improvement of the characteristics of asphalt concrete is achieved through the introduction of additives that affect the basic properties of the bituminous binder, such as penetration, softening temperature, viscosity. The influence of the chemical composition of the mineral filler on the rate of bitumen aging has been experimentally proved. The obtained research data show that the increase in the rate of aging of bitumen is influenced by the compounds of silicon and aluminum. On the other hand, metals such as iron and titanium contribute to the preservation of the initial plasticity of bitumen, and the accumulation of asphaltenes in the structure of the bitumen-mineral mixture slows down.

Effect of Dietary Supplementation of Organic Minerals on Growth Performance of Broilers

A study was conducted to assess the effects of replacing inorganic ‘zinc’ and ‘manganese’ with different levels of their organic complexes on growth performance and nutrient metabolizability of broilers. Experiment was conducted with 300 broiler chicks randomly divided into six groups, each consisting of 50 broiler chicks. All groups were further subdivided into five replications each containing 10 broiler chicks. The basal ration was formulated as per BIS (2007) specifications to meet energy and protein requirements of birds. In experimental groups, first group was kept as negative control (T1) containing mineral mixture without ‘zinc’ and ‘manganese’ and T2 (positive control containing mineral mixture with inorganic salts of ‘zinc’ and ‘manganese’) while experimental groups T3, T4, T5 and T6 were supplemented with mineral mixture incorporated with organic ‘zinc’ and organic ‘manganese’ @ 50 and 100% in substitution of their inorganic sources. The highest body weight gain (2334.4g) and improved FCR (1.76) in broilers was observed in T6 group which was significantly (P<0.05) better than negative and positive control groups.

​Induction of Postpartum Oestrus in Lakhimi Cows through Hormonal and Nutritional Interventions

Background: Postpartum anoestrus is the most devastating cause of the dairy farming which causes more economic losses to the farmers. The present study was conducted to record the incidence of postpartum anoestrus and to evolve a suitable therapeutic regime for addressing postpartum anoestrus in Lakhimi cows. Methods: A total of 1000 Lakhimi cows maintained in different villages of Assam were selected and the incidence rate was recorded on the basis of breeding records provided by the farmers, per-rectal examination and ultrasonography screening of genital organ. To study the effect of hormonal and nutritional interventions in post partum anoestrus cows, the cows were divided randomly into seven groups comprising twelve animals in each group. The different treatment regimes were Hydroxyprogesterone caproate + eCG, Clomiphene citrate alone, Clomiphene citrate + Mineral mixture, GnRH analogue alone, GnRH analogue + Mineral mixture, Mineral mixture alone and control. The response to different treatment regimes was based on oestrus response, mean interval from the end of treatment to onset of oestrus and conception rate. Result: The incidence of postpartum anoestrus was found to be 20.60%. Clomiphene citrate + Mineral mixture administration regime brought about the highest oestrus induction response (100.00%) and conception rate (66.67%).

Challenges to Overcome by the Members of the NARMUL Dairy Cooperative

Dairy cooperatives have played an important role in improving the economy of small milk producers’ households in different regions of India. Telangana is one amongst them, which is predominantly an agricultural state with an excellent potential for milk production. The study was conducted to analyze the constraints faced by dairy farmers of Yadadri- Bhongir district of Telangana. The study data was collected during March-April 2021 from 90 milk producers of NARMUL co-operative in Yadadri-Bhuvangiri district of the state. Low procurement price of milk, Lack of disease control programs, No Bonus, Lack of milk testing & animal screening facilities, Irregular visits of Veterinary staff were considered as the most serious constraints where as, Unavailability of first aid services and lack of sufficient supply of vaccines to the animals, Non availability of loan facilities, Lack of artificial insemination (A.I.) facilities in/around the village, Inadequate supply of feed and mineral mixture were considered as the least serious constraints.

Effect of Energy Supplementation On Intake, Digestibility of Diets and Performance of Grazing Lambs During The Rainy Season

This study aimed to evaluate different energy sources in multiple supplements on performance, intake and digestibility of Santa Ines sheep grazing urochloa grass (Urochloa mosambicensis) during the rainy season. The experimental area was divided into seven paddocks of four-ha each, with an average of dry matter (DM) availability of 3213.45 kg/ha. A completely randomized design was carried out, in which there were four treatments, and each treatment was repeated six times. Twenty-four intact lambs (average: 32 kg of body weight) were supplemented with a mineral mixture, the control group (MM), mesquite pod meal (MPM), wheat bran (WB) or sorghum grain (SG) as energy sources. The digestibility of DM and crude protein (CP) in MPM, and WB is higher than in MM and SG groups. The DM digestibility was higher in the WB group; however, there was no difference between the other treatments. Neutral Detergent Fiber (NDF) digestibility was similar between supplemented lambs, and it was higher than the MM. The supplementation promoted higher weight gain than in the control group (0.125 vs. 0.61 g/day, respectively; P < 0.001). The supplementation increased the DM, and CP intake. The NDF intake only increased in the WB group. The CP digestibility was higher for the MPM and WB groups than for MM and SG ones (P < 0.001). Sheep supplementation in the rainy season increased the average daily gain (ADG). Any supplement tested in the present study can be used during the rainy season. The choice for the supplement will depend on the availability and costs of the supplement.

Environmental impact assessment of preventive emulsion based on heavy oil residue on organic pollution of water

Introduction. Dusty surfaces insulation with preventive emulsions based on heavy oil residue (HOR) is a promising environmental technology in open-pit mining. To assess the environmental safety of these emulsions, it is required to assess the possible scale of organic pollutants emission into the technogenic leakage fluxes occurring due to the interaction of HOR insulation with precipitation. Research aim is to assess the scale of organic pollutants leaching occurring due to the interaction of HOR insulation with precipitation. Research methods. Laboratory modeling of HOR samples and water interaction and assessment of the scale of organic compounds (bitumen and oil products) discharge into the water environment. Results. Studies have shown that the addition of an insulating emulsion based on heavy oil residue leads to the creation of an organo-mineral mixture with hydrophobic properties, determining low solubility of hydrocarbons in water and posing no threat of excess organic pollution to the hydrosphere.
