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> https://ijlr.org/ojs_journal/index.php/ijlr/article/view/154 Role of Prelay Nutrition in Modern Layer Management 2022-11-21T15:26:03+00:00 Vijaysingh Lonkar vijulvet1982@gmail.com <p><em>Genetic, nutritional, and management efforts were adopted to extend the laying cycle with efficient production in layers. The poultry industry targets layers to get 500 eggs in a 100-week laying cycle positively impacted by manipulating the pullet nutrition because the layer's performance depends on her pullet stage performance. If the feeding programs for pullets are well designed and implemented, egg producers can take advantage of today's modern layer's tremendous genetic potential. The prelay period typically begins two to three weeks before the ovulation of the first ovum. Substantial body reserves before egg production (prelay period) are indispensable to achieve satisfactory hen performance. At the onset of egg production, calcium reserve are crucial in maintaining egg production and eggshell quality. A prelay diet with moderate calcium (2.0-2.5%) allows for the build-up of the medullary bone calcium reserves and maintains eggshell qualities. Dietary energy and protein are the critical nutrients in maturing pullets. The egg production performances improved by feeding pullets with high-energy and high-protein diets during the prelay period. Feeding a prelay diet containing 2700 kcal ME/kg diet and 18% CP with 2.0-2.5% calcium is the best combination for pullets 2-3 weeks before the start of egg production.</em></p> 2022-12-31T00:00:00+00:00 Copyright (c) 2023 Vijaysingh Lonkar https://ijlr.org/ojs_journal/index.php/ijlr/article/view/146 Influence of Different Types of Mutton Substrates on The Breeding Preferences of Necrophagous Flies 2022-12-21T22:41:31+00:00 P.

On day one of the experiment, the adult flies were recorded in group M1 and no flies were attracted to the remaining groups (M2 </em><em>–</em><em> M4). Fly eggs and first larval instars started to appear in the M1 group from the 2nd day onwards. By the 4th day onwards, adult flies, eggs as well larval instars were noticed in all the groups (M1 </em><em>–</em><em> M4). On the final day of the experiment, L3 stages were recorded with a varying number of all types of meat samples of mutton. In the present study, flies were attracted more immediately to fresh mutton meat than to remaining formulations. Other forms of mutton viz., cooked, salt, and turmeric treated and frozen samples were observed in the flies only after a day of its placement. The larvae obtained from fresh mutton (M1) samples were of Calliphora spp. (60%) and Lucilia spp. (40%). The majority of the dipteran larvae in cooked mutton (M2) were of Chrysomya spp. (73.3%) and the remaining (26.7%) were of Musca spp. In the third group of salt and turmeric powder treated mutton sample (M3), the obtained larvae were identified as Sarcophaga spp. (n=16) and the rest of the larvae were of Chrysomya spp. (n=14). The findings revealed that different Physico-chemical characteristics and also the proximate composition of mutton had significantly (P&lt;0.05) influenced the breeding preferences of flies.</em></p> <p> </p> 2022-12-31T00:00:00+00:00 Copyright (c) 2023 P.

Chicken Infectious Anemia (CIA) caused by a Circovirus is one of the very important viral diseases. During the present study, mortality of 15 to 25% due to Chicken infectious anemia in eleven, 6-11weeks old commercial layer flocks located at Durg, Rajnandgaon, and Raipur districts of Chhattisgarh was noticed which were not vaccinated against CIA. Characteristic clinical signs of anemia indicated by pale comb and wattle, yellowish changes in the bone marrow, and thymic atrophy were suggestive of CIA. Generalized lymphoid atrophy was the most constant and characteristic lesion found in CIA-affected birds. Clinical samples of thymus collected from eleven commercial layer flocks were confirmed as CIA by PCR amplification of 419bp of the VP2 gene of the virus. The clinical signs, gross and histopathological findings along with PCR amplification of the VP2 gene confirmed the outbreak of CIA in the commercial layer.</em></p> 2022-12-31T00:00:00+00:00 Copyright (c) 2023 Prashant M.
