Efficacy and Safety of Neem Oil for the Topical Treatment of Bloodsucking Lice Linognathus stenopsis in Goats under Field Conditions. Animals (Basel) 2023; 13:2541. [PMID: 37570349 PMCID: PMC10417451 DOI: 10.3390/ani13152541] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 08/03/2023] [Accepted: 08/05/2023] [Indexed: 08/13/2023] Open
Abstract
The aim of the present study was to evaluate the efficacy and safety of neem oil on caprine pediculosis and on kids' growth performances. The neem (Azadirachta indica) belongs to the Meliaceae family, and in Eastern countries it is mainly considered for the insecticidal activities of the kernel oil. The neem seeds contain bioactive principles, such as azadirachtin A, salannin, nimbin, and nimbolide. The trial was carried out on 24 kids, 120 days old, maintained in open yards. Animals were divided in 4 homogeneous groups (n = 6 animals/group) based on age, louse count, body condition score (BCS) and live body weight: Control Group (C, saline NaCl, 0.9%), Neem Group 1 (NO-100, 100 mL of neem oil per 10 kg), Neem Group 2 (NO-200, 200 mL/10 kg), Neem Group 3 (NO-300, 300 mL/10 kg). The treatments were performed by spraying the insecticide on the goat's body. The study lasted 56 days, and weekly, the kids underwent louse count, BCS and body weight determination, and FAMACHA score. Data were analyzed by ANOVA for repeated measures. The species of lice identified was Linognathus stenopsis. Kids belonging to NO-200 and NO-300 showed a stronger reduction of louse count throughout the study (>95%). The daily weight gain recorded was significantly higher (p < 0.05) in NO-300 than C. No differences were found for BCS and FAMACHA scores. The results of this trial showed that the administration of neem oil to control caprine pediculosis caused by sucking lice represents an alternative to synthetic compounds.

Ajith Y, Dimri U, Gopalakrishnan A, Devi G. A study on prevalence and factors associated with ectoparasitism in goats of two agro-climatic regions in India. J Parasit Dis 2017; 41:739-746. [PMID: 28848271 DOI: 10.1007/s12639-017-0881-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2016] [Accepted: 01/11/2017] [Indexed: 10/20/2022] Open
Abstract
The present study was aimed to evaluate the factors associated with prevalence of various ectoparasites among goats during winter season in two different agro-climatic regions of India. A total of 320 goats (Uttarakhand-208; Uttar Pradesh-112) were screened and evaluated for ectoparasitism and associated factors. The occurrence of ectoparasitism in goats was studied in relation with age, sex, breed, housing, agro-climatic region and system of rearing. Prevalence of ectoparasitism among goats of lower Shivalik region (Dehradun and Tehri Garhwal districts) of Uttarakhand and Bareilly district of Uttar Pradesh was 90.38 and 39.29%, respectively. The common ectoparasites observed were chewing lice (Bovicola caprae), sucking lice (Linognathus africanus), fleas (Ctenocephalides felis) and ticks (Haemaphysalis spp.). Among all the ectoparasitic infestation, pediculosis was the most common affection during the study period in both agro-climatic region; chewing lice in Uttarakhand and sucking lice in Uttar Pradesh. Agro-climatic region, breed, immune status, system of rearing and hygiene were highly affecting the prevalence and distribution of ectoparasites among goats. High prevalence of ectoparasitism in the study area warrants the need for formulating appropriate intervention strategies to improve control of ectoparasites and awareness among goat farmers.
