Abstract

This study was conducted to determine the efficacy of anthelmintics against gastrointestinal parasite in periparturient dairy cows and its effect on milk yield and quality. Sixty mixed breed pregnant cows were selected divided into four groups, A (n=18), B (n=14), C (n=16) and D (n=12) and group D kept as control. Cows of group A were treated with Nitroxynilat the rate of 10 mg/kg bwt. s/c, 30 days before parturition and average feacal egg per gram(EPG) was reduced from 506.1 ± 172.3 to 157.8 ± 24.9 within 14 days. Group B were treated with combined triclabendazole and levamisoleat the rate of19.5 mg/kg bwt. orally at calving. The average EPG was reduced from 967.7 ± 237.1 to 172.0 ± 25.9. Group C were treated with same as group B at calving and 42 days after. The mean EPG fall from 794.6 ± 310.5 to 166.7 ± 26.2.In group D average EPG increased from 791.7 ± 268.5 to 864.2 ± 290.7. The mean change in EPG 14 days after treatment was significantly higher (p<0.05) in treated (79.1%) cows than control (-9.2%). The average milk yield in all treated cows was significantly (p<0.01) higher in treated lactation (2.5 ± 0.7) than previous lactation (2.2 ± 0.7) and control cows (2.2 ± 0.8). Although, milk yields were higher in second parity (2.5 ± 0.7) than the first (2.4 ± 0.7), there was no significant difference (p>0.05). The percentage of milk fat, protein, lactose, SNF was significantly higher (P<0.05) in treated group than the control group.Asian J. Med. Biol. Res. September 2016, 2(3): 409-413

Highlights

Milk has long been recognized as an valuable food of pastoralist diets in all the world, it is a nutrient food and is recognized to contribute a high proportion of the nutrients, such as micronutrients, include calcium, phosphorus, vitamins like B and D, high quality protein such as casein protein, fatty acid composition of milk fat has relation to its potential health benefit and impact on the human health (Frelich et al, 2012)
Cows of group A were treated with Nitroxynilat the rate of 10 mg/kg bwt. s/c, 30 days before parturition, Group B were treated with combined triclabendazole and levamisoleat the rate of 19.5 mg/kg bwt. orally at calving, Group C were treated with same as group B at calving and 42 days after and samples were collected from over a period of one year fromJuly 2014 to June 2015
The efficacy of anthelmintic treatment at different stages of periparturient periods have been presented in Table

Summary

Introduction

Milk has long been recognized as an valuable food of pastoralist diets in all the world, it is a nutrient food and is recognized to contribute a high proportion of the nutrients, such as micronutrients, include calcium, phosphorus, vitamins like B and D, high quality protein such as casein protein, fatty acid composition of milk fat has relation to its potential health benefit and impact on the human health (Frelich et al, 2012). Fresh cow milk contains approximately 3.5% protein, 80% casein, 15% whey protein, as well as vitamins, and lipids, all of which provide necessary ingredients for growth (Heck et al, 2008).Different factors, such as race of cows, genetic variants, stage of lactation and environmental factors which can significantly affect on milk component and properties of milk (Bernabucci et al, 2002).
