White Leghorn hens with low productivity inoculated parenterally with a plant biostimulator (Eichornia crassipea). II. Egg Quality
Abstract
In order to determine whether a plant biostimulator parentally inoculated proved to be useful in regaining previous laying per- formance levels after their decrease due to unfavorable feeding conditions, 432 White Leghorn layers with a nine-month produc- tive lifespan were sampled. Treatments applied were: I 0 mL biostimulator; II 1 mL leaf biostimulator; III 2 mL leaf biostimula- tor; IV 1 mL petiole biostimulator; V 2 mL petiole biostimulator. The principal results for morphological indexes yolk and egg white (%) and Haugh units, per each treatment, respectively were: 73,9a; 74,1a; 64,9b; 73,1a y 72,7a (p<0.05); 42,8; 45,3; 44,9; 43,8 y 41,7 (NS); 7,7; 8,1; 9,0; 9,1 y 8,9 (NS); 82,1b; 83,8b; 90,8a; 87,1ab y 86,7ab (p<0,05). Apparently biostimulator paren- tally inoculated does not alter eggs quality.
