Abstract:

Introduction
Many plant species have developed a wide array of defense mechanisms . A very pronounced one is the production of tannins that sharply decrease palatability ,feed intake ,various enzyme activities ,nutrient availability ,and animal performance ( Makhar 2003) . On a yearly basis ,free‐ranging adult Damascus goats consume more than twice as much tannin‐rich P .lentiscus ( 22% ) than do Mamber goats ( Glasser et al . 2006) .Are Damascus kids born with this ability ,or is this learned from the kids' mother ? The aim of this study was to quantify the behavioral effects of the educating " mothers摧 breed vs .breed of kid in domestic goats of two breeds ,as related to intake of tannin‐rich browse .

Materials and methods
Goats used for this research were of Damascus and Mamber breeds ,which are commonly raised in the Eastern Mediterranean region . Experiments took place at the Ramat‐Hanadiv Nature Park" , located at the south of Israel摧s Carmel mountain ridge ,an area dominated by dense Mediterranean shrubland . Treatments consisted of three groups : kids reared by their biological mothers ,cross‐fostered kids of the reciprocal breed ,and kids fed by a milk‐powder dispensing machine ( artificial mother") from birth .Treatments were applied to three groups of three kids of each breed ,except for Damascus kids fostered by Mamber does ,which consisted of two groups ( total of 17 groups) . Experiments were conducted at two different developmental stages of kids' growth : Na甭ve"‐before weaning ,when kids had only started to eat dry food without grazing ,and Experienced"‐after kids from each group had grazed separately with biological ,fostering ,or no mothers . Two experiments were conducted . During Experiment 1 ,kids were exposed for five minutes daily to P .lentiscus or P .lati f olia containing 22 and 3% PEG‐binding tannins ,respectively ,for 2 periods of 6 days each .In Experiment 2 ,kids were exposed to both browse species simultaneously for 2 periods of 3 days each . Figure 1 Intake o f P .lentiscus in kids摧 diets during Ex periment 2 .

Results
In both experiments ,experienced kids consumed more browse than did na甭ve kids ,when calculated per metabolic BW ( F1 ,50 = 90 .3 ,P < 0 .0001) . Kids did not exhibit higher propensity to ingest P .lentiscus or P .lati f olia when given alone during Experiment 1 .During Experiment 2 ,na甭ve kids consumed the same proportions of P .lentiscus and P .lati f olia as well . However ,diets consumed by experienced kids raised by Damascus does ,milk‐dispenser or Mamber does consisted of 45 .8 ,48 .1 and 24 .3 g / kg ‐0 .75 of P .lentiscus ,respectively ( F2 ,20 = 5 .0 ,P = 0 .01 ,Figure 1) .

Conclusions
These results suggest a strong maternal educative" effect on kids' dietary selection for tannin‐rich browse ,as opposed to the kids' breed ,which did not exhibit any effect on intake of P .lentiscus at the na ?ve stage .The findings regarding the Mamber‐mother group lead to the conclusion that dietary selection regarding tannins is passed from mother to kid by avoidance ( or the absence of it ,i .e . artificial mother" group) rather than learning to prefer a specific plant species .
