Effect of Rocket Oil Addition on Preductive and Reproductive Performance and Some Blood Parameters of Zaraibi Goats

Abstract

Thirty-six Zaraibi doe goats of 3-5 years old and average live body weight (LBW) of 28.14±0.93kg were randomly distributed into three groups (12 doe goats in each) according to their LBW and reproductive status. The experimental period of does lasted for 12 months and buck treatment started two months before breeding season in September. Mating was carried out using twelve sexually mature fertile and tested bucks of 41.25±2.1 kg LBW and aged 24 months were divided into three groups receiving the same treatments of doe goats.Rocket oil (watercress oil) was received daily oral does at levels of 0, 1 and 2 mg/kg LBW for G1, G2 and G3, respectively. The results showed that the bucks in G3 showed the highest (P<0.05) scrotal circumferences (30.25 cm), followed by G2 (29.25 cm) and G1 (27.75 cm) at the end of experiment. Bucks in G3 showed the lowest (P<0.05) reaction time and abnormal sperm percentage and the highest (P<0.05) ejaculate volume, and percentages of sperm motility, and live sperm, as well as sperm concentration and total sperm output compared with G2 and G1. Fertility rate was 90, 100 and 100% for mated does and 75, 91.66 and 91.66% for all treated does in G1, G2 and G3, respectively (P<0.05). Litter size and sex ratio were the highest (P<0.05) in G3 and G2 compared with G1, while mortality rate was the lowest (P<0.05) in G3 (6.26%), followed by G2 (11.11%) and G1 (15.38%). Weaning weight, total gain and average daily gain of born kids were higher (P<0.05) in G3 than in G2 and G1. Average daily milk yield was higher (P<0.05) in G2 and G3 than in G1, being 1318 and 1426 vs. 1162 g, respectively. Percentage and yield of milk constituents were higher (P<0.05) in G2 and G3 than in G1. Only, concentration of serum albumin increased (P<0.05) with rocket oil additive as compared to G1, while the other blood parameters were insignificantly different among the experimental groups. Does in G3 showed the highest economic feed efficiency for milk production as compared to those in G2 and G1.

“…In addition, Hussein, 2013, Salem and Moustafa (2001) said that E. sativa improves healthy sperm characteristics and fertility. Ejaculate volume, percentages of motility and sperm concentration was significant (P<0.05) increase in the group of buck goat fed a diet containing 2 mg/Kg rocket seed oil as compared with control group (Hafez et al, 2016). El-Nattat and El-Kady (2007) found that the total function sperm fraction, total sperm per ejaculate, and total mobile sperm of buck rabbits was augmented by supplementary black cumin, radish, and rocket meal (at a level of 50%, respectively) and a mix of these meals at a level of about 17% each as a substitute for soybean meal.…”

“…on the other hand, NS or ES seed supplementation significantly decreased values of ALT, AST (Yavari et al, 2021 ; Abou El-Maaty et al, 2021 ) and urea-N (Mohammed and Al-Suwaiegh, 2023 ). In the same trend, dietary supplementation with ES oil had no significant effect on blood ALT, AST, urea, and creatinine (Hanafi et al, 2010 ; Hafez et al, 2016 and El-Badawy et al, 2018 ).…”

“…These observations agree with results obtained by Zanouny et al ( 2013 ), Fayed and Azoz ( 2018 ), and El-Gindy et al ( 2020 ) when either NS or ES seeds were added to the diets of rabbits or lambs. Similarly, the addition of ES oil significantly reduced both levels of cholesterol and triglycerides (Hafez et al, 2016 ; El-Badawy et al, 2018 and El-Giziry et al, 2021 ). Contrarily, Mustafa et al ( 2022 ) reported no significant effect on blood cholesterol and triglycerides with NS oil addition to the diets of Karadi lambs.…”

“…However, concentrations of TP, albumin, and globulin were not significantly altered by the addition of NS seeds in lambs’ and buffaloes’ diets (Odhaib et al 2018a ; Abo El-Nor et al 2007 , respectively). Also, blood TP and globulin were significantly unchanged with ES addition either in the form of seeds (Fayed and Azoz, 2018 ) or oil (Hanafi et al, 2010 ; Hafez et al, 2016 ). In contrast, Khalil et al ( 2015 ) and El-Badawy et al ( 2018 ) showed significant increases in TP and albumin with the addition of ES seeds or oil to fish or lambs’ diets, in the same order.…”
