The marginal and landless farmers in India regard goat as “poor man’s crop” and “mobile bank”. Goat occupies a special place in the rural economy of Tamil Nadu. Tamil Nadu is endowed with three meat type breeds of goats viz., Kanni Adu [12], Kodi Adu [5] and Salem Black [9]. Salem Black goats, the recently recognized native goat breed of Tamil Nadu are distributed in Salem, Dharmapuri, Krishnagiri, Erode and Namakkal districts and are reared for meat, skin and manure [1]. The Salem Black goats have good production potential in terms of early sexual maturity and prolificacy. Salem Black goats were reported to produce 48.6 per cent of multiple births (twins 40 per cent, triplets 8.2 per cent and quadruplets 0.4 per cent) under farmer's field conditions [9]. Birth weight is the first observed trait in the life of animal on which growth, production and reproduction traits are dependant. So, the present study was undertaken to investigate the various non-genetic factors affecting birth weight of the kids born under farm conditions.
This study is based on the assessment of the state of the Toumiet-Sud forest, located in the Sidi Bel Abbès province, which was devastated by a major fire in 2012. It highlights the importance of using remote sensing tools and integrating aerospace and cartographic data into a geographic information system (GIS). The analysis of the vegetation index derived from the three processed images from 2010, 2012, and 2020 showed a variation in the radiometry of the fire-affected areas. The results, verified through field investigations, revealed heterogeneous regeneration throughout the entire study area, with a notable recovery of the Algerian fir (Tetraclinis articulata).
Phytoremediation is a sustainable and eco-friendly approach that uses plants to remove water contaminants. It shows great promise in addressing water pollution. The aim of this study is to evaluate the effectiveness of phytoremediation in treating water contaminated with various pollutants. The study specifically investigates the impact of ethylenediaminetetraacetic acid (EDTA) on the growth and physiology of Arundo donax, a plant used in lead (Pb) phytoremediation. Response surface methodology is used to optimize experimental conditions to maximize Pb removal by Arundo donax. The results demonstrate that the use of EDTA enhances the solubility of Pb in water, making it easier for the plant's roots to absorb it. There are significant correlations between the concentrations of Pb, the time of sampling, the use of EDTA, and the amount of Pb eliminated. The validity of our model and the significance of the studied factors were confirmed through analysis of variance (ANOVA). The results highlight the potential of using EDTA-assisted Arundo donax for Pb phytoremediation. This research contributes to the development of sustainable and efficient methods for mitigating Pb-induced water contamination, which is crucial for protecting human health and the environment.
Ghee residue is a by-product of dairy-industry involving in manufacture of ghee. Ghee residue was analyzed for its proximate composition, gross and metabolizable energy content, complete amino acid, fatty acid and mineral profiles. It was also assessed for apparent digestibility of crude protein, amino acids and retention of minerals in poultry. The dry matter, crude protein, ether extract and total ash contents (per cent) in ghee residue were 90.19, 25.71, 51.35 and 4.83 respectively, with no crude fibre. The gross energy of ghee residue was 7279 kcal/kg. The lysine, methionine, threonine and arginine contents in ghee residue were 0.98, 0.51, 1.28 and 0.79 per cent, respectively. The linoleic and linolenic acid contents of ghee residue were 2.22 and 0.33 per cent of fat, respectively. The calcium, phosphorus and magnesium content were 0.78, 0.72 and 0.73 per cent, respectively. The content of copper, iron, manganese and zinc in ghee residue were 18.18, 138.26, 9.47 and 28.97 mg/ kg, respectively. The apparent and true metabolizable energy content of ghee residue were 5570 and 5839 kcal/kg ghee residue, respectively. The apparent digestibility of crude protein was 67.96 per cent and the digestibility of lysine was found to be the lowest (66.86 per cent) among amino acids. The mineral retention study revealed that the retention of calcium, phosphorus and magnesium were found to be 57.40, 44.55 and 88.80 per cent, respectively. Similarly, the retention coefficient of copper, iron, manganese and zinc were 55.10, 57.99, 36.58 and 35.06 per cent, respectively. The finding revealed the potential of ghee residue as an energy as well as protein source and suggested that ghee residue may conveniently be considered as an alternative source of high energy poultry feed ingredient and simultaneously as a good protein source when supplemented with limiting amino acids.
Two hundred and fifty six broiler chicks were randomly grouped into eight treatments and were fed diet without (T1) or with supplementation of antibiotic growth promoter (T2), or with supplementations of lemongrass oil at 100 mg/kg diet (T3), 200 mg/kg diet (T4), 300 mg/kg diet (T5) or thyme oil at 100 mg/kg diet (T6), 200 mg/kg diet (T7) and 300 mg/kg diet (T8). The experiment revealed that T1 had significantly lowest body weight and weight gain among all treatment groups. The groups T3, T4, T6 and T8 did not differ significantly with T2, whereas, T7 and T5 had significantly higher body weight gain than T2 and control. No significant difference was observed among treatments groups in cumulative feed intake. At the end of experimental period, the feed conversion ratio of broilers was significantly better in T7 followed by T5 and T8, than T6, T4, T3 and T2, whereas the control (T1) recorded poorest feed conversion ratio. There was no significant difference in livability among treatment groups. The group T8 had significantly higher villi length followed by the groups T7 and T6 than other treatment groups, whereas it was lowest in T2. All the groups fed with the essential oils recorded significantly higher apparent digestibility of protein and retention of calcium and phosphorus than T1 and T2. The groups T5, T4, T3 had significantly lower total cholesterol in serum, breast and thigh muscle than control (T1) and antibiotic supplemented group (T2). Return over feed cost was highest in T7 and it was lowest in control group. The supplementation of antibiotic (T2) increased the return-over-feed cost (ROFC) than control. The groups T3 and T6 produced comparable ROFC with T2, but T4, T5 and T8 produced higher ROFC than T1, but lesser ROFC than T2. Hence, it may be concluded that lemongrass oil up to 100 mg/kg or thyme oil up to 200 mg/kg broiler diet could be supplemented as an alternate to antibiotic growth promoter, without compromising the economics of broiler farm.
