IJLR promotes the sound development of the livestock sector by publishing original, peer-reviewed research and review articles covering all aspects of this broad field. The journal welcomes submissions on the avant-garde areas of genetic resources, tropical livestock farming, welfare, ethics and behavior, in addition to those on genetics, breeding, growth, reproduction, nutrition, management, health, production, systems, and so on. The high-quality content of this journal reflects the truly international nature of this broad area of research.</p> Pashupati Foundation India en-US International Journal of Livestock Research 2277-1964 <h2>Attribution 4.0 International</h2> Molecular Detection of Certain Virulence Genes of Avian Pathogenic Escherichia coli (APEC) in Chicken https://ijlr.org/ojs_journal/index.php/ijlr/article/view/84 <p><em>In the present study, 86 avian pathogenic E. coli isolates from chicken were subjected to multiplex PCR to detect the presence of virulence genes stx1, stx2, eaeA, and hlyA. Forty-seven isolates harbored one or more virulence genes, stx1, stx2, and eaeA while gene hlyA was not detected in any of the samples. Of these, 15 (17.44%) isolates harbored stx1gene, 11 (12.79%) isolates carried stx2 gene, 18 (20.93%) isolates were positive for both stx1 and stx2 genes and 3 (3.49%) isolates carried eaeA gene.</em></p> Tarakeswara Rao M Rama Devi V Sreedevi C Srinivasa Rao T Sudha Rani Chowdary CH Annapurna P Copyright (c) 2022 M.

Egg production parameters and egg quality were studied in 240 layers in a completely randomized design in 5 treatments with 6 replications of 8 birds in each. ICAR 2013 specifications for improved native chicken breeds were followed for formulating the control diet (T1) which was based on corn soya bean meal with 16% CP and 2700 kcal ME. The diets T2 to T5 were made isocaloric to control and composed with 15.5,15,14.5 and 14% CP respectively, ensuring the levels of limiting amino acids namely methionine lysine, threonine as that of control by adding synthetic preparation. The data on egg production parameters are presented on the basis of hen day egg number, feed efficiency on a dozen egg basis, and period-wise egg weight (EW) during 29- 40 weeks remained statistically non-significant among various dietary groups. The values for eggshell thickness recorded in CP reduced groups (T3, T4, and T5) were comparable with control (T1) except T2 and also comparable among themselves. The mean shape index, albumen index, yolk index, and Haugh Unit score did not show any significant difference among various dietary treatments. In summary, the crude protein content of the Swarnadhara layer diet can be reduced to 14% by limiting AA fortification without any adverse effect on egg production and egg quality during 29-40 weeks of age.</em></p> Beena C Joseph Erinjery Jaya Naik Binoj Chacko C.

Data were collected from 7 bucks, 35 does, and 58 of their progenies and analyzed using the SAS computer program (2000). The result indicated that the survivability and growth performance of kids were significantly (p&lt;0.05) affected by the milk yield, body condition score, and parity of does as well as buck. Moreover, the results also revealed that the litter size and milk yield of the does were significantly (p&lt;0.05) affected by the body condition score and parity. The highest survivability of the kids was noticed in the case of dams with milk yield &gt; 600 ml per day, body condition score 2, and parity 3. The highest birth weight (1.38</em><em>±</em><em>0.16 kg) and body weight at the different stages were found by using buck ID No. 01. On the other hand, in respect of milk yield and body condition score, the highest birth weight and growth performance were observed in dams with milk yield &gt;600 ml per day and a body condition score of 3. However, the highest litter size (2.00</em><em>±</em><em>0.39) was observed in dams with a body condition score of 2. Similarly, in the case of parity, the highest litter size (1.60</em><em>±</em><em>0.5) was found in dams with parity 2. Besides these, the maximum milk yield was found in dams with a body condition score of 4 in parity 2, and the lowest in dams with a body condition score of 2 in parity 1. Therefore, the study revealed that the milk yield, body condition score, and parity of does play a significant role in the survivability and growth performance of the kids. So, it can be concluded that these factors must be considered for improving the growth performance and survivability of the kids.</em></p> M. S. Begum S. A. M. Hoque Md. Younus Ali M. A. M. Y.

Palpation of the cervical part of oesophagus revealed a pliable mass. Based on the history, clinical signs, clinical findings and inability to pass the stomach tube beyond the palpable mass, the case was diagnosed as intraluminal obstruction of the cervical oesophagus. Cervical oesophagotomy revealed that the obstruction was caused by the lodging of carrot and radish into the oesophagus.</em></p> P.Sankar S. Dharmaceelan P. Vidya Sagar V. Venkatesh S.
