Silage, which is anaerobically fermented green fodder, is valued throughout the world as a source of animal feed during lean months. Several farms in India use carbohydrate sources like jaggery or molasses at 2% for preparation of silage, and this increases cost of production. The present study was undertaken to assess the effect of jaggery on quality and intake of maize silage, with an objective to find out whether additional carbohydrate source is essential in preparation of silage using green maize. Three silage types, one without jaggery (A), the second with 1% jaggery (B), and the third with 2% jaggery (C) were prepared in cylindrical bins under similar conditions. They were compared for colour, pH, lactic acid bacteria count, lactic acid content, proximate composition and silage intake by sheep. Silage type C with 2% jaggery was significantly different from the other two types with values of 3. 98 and 805. 66 g for pH and mean silage intake, respectively. Even though the values of pH and dry matter intake for all three silage types were within normal levels, silage type C was significantly superior in terms of fermentation and palatability. The method of preparation followed could be ideal for small holder farmers requiring less quantity of silage. © 2009 Springer Science+Business Media B.V.

Kleiber ratio (KR) is an indicator of growth efficiency irrespective of body size. The trait was recommended as an efficient indirect selection criterion. The present study was done to estimate genetic parameters for KR and explore the possibility of its use as a selection criterion in Nilagiri and Sandyno sheep. KR for the pre-weaning (birth to 3-months) and post-weaning (3- 6, 6-9, 9-12 and 3-12 months) periods was studied. Pre-weaning KR was much higher than post-weaning KR in both the breeds. The mean pre-weaning KR for Nilagiri and Sandyno sheep was 14.37 and 14.52, respectively. All the post-weaning KR values were less than six. Animal model including or ignoring maternal effects was used to obtain REML estimates of (co)variances. The best model was chosen based on log-likelihood ratio test. Maternal effects and inbreeding were not significant for KR at any of the age intervals. Moderate estimates of heritability were obtained for pre-weaning KR in both the breeds. Among the post-weaning KR, the age interval from 3-6 months and 3-12 months showed moderate values in Nilagiri sheep. Post-weaning KR for Sandyno sheep showed negligible to low heritability estimates. The maximum heritability of 0.143 was for KR 3-6 months in Nilagiri sheep. In Nilagiri sheep, genetic correlation between pre-weaning KR and body weight traits ranged from 0.634 to 0.875. Similarly, in Sandyno sheep, the values ranged from 0.883 to 0.959. Thus pre-weaning KR could be used as a criterion for indirect selection to improve important body weight traits. © 2016, Indian Council of Agricultural Research. All rights reserved.

The growth records of Nilagiri (1965) and Sandyno (1915) breeds of sheep for the period from 1993-2002 available at the Sheep Breeding Research Station (SBRS), Sandynallah - 643 237, The Nilgiris District were utilized for the study. The effects of breed, season of birth, litter size and sex of the lambs on birth weight, weaning weight, average daily gain (ADG) and mortality were analyzed. The lambs born during the second lambing season (SLS) (2.62 ± 0.06 and 11.9 ± 0.33 kg) were significantly (P<0.01) heavier at birth and weaning and the ADG (102.9 ± 3.24 g) was also significantly higher than lambs born during the main lambing season (MLS) (2.21 ± 0.05 and 9.02 ± 0.31 kg; 74.8 ± 3.24 g). Mortality was higher in lambs born during March (8.80%) than in those born during September (7.03%). Sex of the lamb had a highly significant influence on the birth weight, weaning weight and ADG. The males were heavier, weighing 2.46 ± 0.06 kg, 10.8 ± 0.32 kg and gaining 91.7 ± 3.32 g, than females (2.37 ± 0.06, 10.2 ± 0.32 kg and 86.1 ± 3.29 g). Single born lambs (3.07 ± 0.12 and 11.1 ± 0.06 kg) were heavier at birth and weaning than twins (2.25 ± 0.02 and 9.69 ± 0.12 kg) and triplets (1.93 ± 0.16 and 10.7 ± 0.19 kg). Sandyno lambs had a better birth weight, weaning weight and ADG (2.56 ± 0.06, 10.8 ± 0.32 kg and 90.3 ± 3.33 g) than Nilagiri lambs (2.27 ± 0.06, 10.2 ± 0.32 kg and 87.4 ± 3.28 g).

Conjoined twinning is a rarely existed gross malformation in natural conditions. The term refers to the two individuals united at any part of their bodies. The extraordinary incidences of conjoined twinning cases may reflect important problems on the marine environment. Therefore, the purposes of this study were to report the incidences of Trachurus mediterraneus conjoined twins in Bandırma Bay, Southern Marmara Sea and to discuss the possible causes of them to derive new research questions. Four polyembryonic individuals were collected from three stations of Bandırma Bay Ichthyoplankton Survey in June 2012. The anomalous individuals were observed at the stations, St-9, 10 and 13 (Critical Stations). St-9 was at about 20m depth contour between Karşıyaka town and Dalyan village in western coasts of bay. St-10 and 13 was off Yenice village at about 10 and 30m depth contoursrespectively in the eastern coasts of the bay. The surface temperature, salinity, dissolved oxygen and pH of critical stations were seemed to be normal. Therefore the pollution was considered as the most possible reason of these incidences. © Published by Central Fisheries Research Institute (CFRI) Trabzon
